LVDS phy, LVDS pixel, tx_escape, and rx_esacpe are all on the same MSLICE. They all share the same clock parent. So, setting the parent source or rate affects all of these clocks.

The driver relies on custom platform data (no DT support) and there never were any users of this driver in the mainline kernel. The commit adding the driver mentioned that the driver was tested on S3C6410 NCP board (with Samsung S3C6410 SoC) but the touchscreen device was never added to the board file. This board was removed in v6.3 in commit 743c8fbb90ca ("ARM: s3c: remove most s3c64xx board support"). Remove the driver since there are no users.

The driver relies on custom platform data (no DT support) and there never were any users of this driver in the mainline kernel. It is likely that the driver was (like mcs5000_ts driver) was tested on S3C6410 NCP board (with Samsung S3C6410 SoC), but the touchkey device was never added to the board file. This board was removed in v6.3 in commit 743c8fbb90ca ("ARM: s3c: remove most s3c64xx board support"). Remove the driver since there are no users.

This has been discussed before [1] [2] and an example test case is included at the end of this commit message. Controller drivers that create MSI IRQ domain with MSI_FLAG_USE_DEF_CHIP_OPS and do not override the .irq_set_affinity() irqchip callback get assigned the default msi_domain_set_affinity() callback. That is not desired on controllers where it is not possible to set affinity of each MSI IRQ line to a specific CPU core due to hardware limitation. Introduce flag MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity() unset if the controller driver did not assign it. This way, migrate_one_irq() can exit right away, without printing the warning. The .irq_set_affinity() implementations which only return -EINVAL can be removed from multiple controller drivers. $ grep 25 /proc/interrupts 25: 0 0 0 0 0 0 0 0 PCIe MSI 0 Edge PCIe PME $ echo core > /sys/power/pm_test ; echo mem > /sys/power/state ...

However, drivers (often in trigger handlers) need to access it to iterate over the enabled channels for example (there are other reasons). Hence, a couple of new accessors are being added: * iio_for_each_active_channel() - Iterates over the active channels; * iio_get_masklength() - Get length of the channels mask. The goal of these new accessors is to annotate 'masklength' as private as soon as all drivers accessing it are converted to use the new helpers.

Some paths do have 'num_channels' into account while others don't. As of now, the driver only supports devices with one channel so the above is not really a problem. That said, we'll add support for devices with more than one channel, hence let's properly make the calibration process to work with it.

On some architectures (powerpc), the root node isn't marked with OF_POPULATED_BUS. If an overlay tries to modify the root node on these platforms it will fail, while on other platforms, such as ARM, it will succeed. This is because the root node is marked with OF_POPULATED_BUS by of_platform_default_populate_init() calling of_platform_default_populate() with NULL as the first argument. Loosen the requirement here so that platform devices can be created for nodes created as children of the root node via DT overlays even if the platform bus wasn't populated for the root node.

This API is intended for use by KUnit tests that test code which relies on 'struct device_node's and of_*() APIs. KUnit tests will call of_overlay_apply_kunit() to load an overlay that's been built into the kernel image. When the test is complete, the overlay will be removed. This has a few benefits: 1) It keeps the tests hermetic because the overlay is removed when the test is complete. Tests won't even be aware that an overlay was loaded in another test. 2) The overlay code can live right next to the unit test that loads it. The overlay and the unit test can be compiled into one kernel module if desired. 3) We can test different device tree configurations by loading different overlays. The overlays can be written for a specific test, and there can be many of them loaded per-test without needing to jam all possible combinations into one DTB. 4) It also allows KUnit to test device tree dependent code on any architecture, not just UML. This allows KUnit tests to test architecture specific device tree code. There are some potential pitfalls though. Test authors need to be careful to not overwrite properties in the live tree. The easiest way to do this is to add and remove nodes with a 'kunit-' prefix, almost guaranteeing that the same node won't be present in the tree loaded at boot.

Add some test managed wrappers for the clk APIs so that clk unit tests can write more code in the actual test and less code in the harness. Only add APIs that are used for now. More wrappers can be added in the future as necessary.

The NoCs are turned on and set to a specific frequency at boot time and that is used for the lifetime of the system. Hence interconnect was not considered previously. The same approach was used for PCIe and at that point the consensus was to move to interconnect. Hence implemented the ICC driver and updating the existing USB driver to use the ICC driver. USB uses icc-clk framework to enable the NoC interface clock. Hence the 'iface' clock is removed from the list of clocks. Update the clock-names list accordingly.

This causes messages that wrap around in the circular buffer to be transmitted using 2 DMA transfers. Depending on baud rate and processor load this can cause an interchar gap in the middle of the message. On the receiving end the gap may cause a short receive timeout, possibly long enough to terminate a DMA transfer, but too short to restart a receive DMA transfer in time thus causing a receive buffer overrun. This is especially a problem for devices with high speed UARTs (HSU) where even deep 64 byte FIFO's are not sufficient to handle interrupt latency. The circular buffer has now been replaced by kfifo which requires a SG list with a single entry, which still causes 2 dma transfers when a wrap around occurs. Fix this by allowing up to 2 entries in the sgl.

The reason is: 1) subschemas (-if: ...), still have to match the top-level: pattern: '^clk_uart_baud[0-3]$' 2) there is one compatible that doesn't follow sequential numbering for the clock names (samsung,s3c6400-uart) 3) when limiting the number of clock-names, we also want to enforce sequential names Because of 1) and 2), the patterns can not simply be changed to constant strings, and later overridden in a different subschema (for samsung,s3c6400-uart only). Since we can't populate the top-level clock-names based on the compatible, and because when limiting the number of items we generally want sequential numbers and not a pattern, move the permitted strings into a subschema of its own and populate it based on the compatible: * 'uart clk_uart_baud2 clk_uart_baud3' for the one outlier * 'uart clk_uart_baud0..3' for everything else This way we can avoid having to duplicate the permitted names everywhere. While at it, add blank lines as per the universal style, which is to have blank lines between properties, except where they are booleans. Also add another example using a compatible that uses the default clock-names scheme, as opposed to the existing example that uses samsung,s3c6400-uart's non-default clock-names. This allows testing both versions of the clock-names property when running dt_binding_check.

The `range_ni_E_ao_ext` variable is tentatively defined in "ni_stc.h" (with internal linkage) and fully defined in "ni_mio_common.c". "ni_stc.h" and/or "ni_mio_common.c" are included by the "ni_atmio", "ni_pcimio", "ni_mio_cs", and "ni_routes_test" modules, which will each get their own local `range_ni_E_ao_ext` variable defined. However, it is not used by the "ni_mio_cs" or "ni_routes_test" modules. They should get optimized out, but there are compiler warnings about the unused variable when built with the `W=1` option. Move the full definition of the variable from "ni_mio_common.c" into the places where it is used, namely "ni_atmio.c" and "ni_pcimio.c", and remove the tentative definition of the variable from "ni_stc.h". This fixes the compiler warnings.

When a process is frozen, it cannot, by design, accept and/or respond to binder transactions. As a result, the sender needs to adjust its behavior, such as postponing transactions until the peer process unfreezes. However, there is currently no way to subscribe to these state change events, making it impossible to implement frozen-aware behaviors efficiently. Introduce a binder API for subscribing to frozen state change events. This allows programs to react to changes in peer process state, mitigating issues related to binder transactions sent to frozen processes. Implementation details: For a given binder_ref, the state of frozen notification can be one of the followings: 1. Userspace doesn't want a notification. binder_ref->freeze is null. 2. Userspace wants a notification but none is in flight. list_empty(&binder_ref->freeze->work.entry) = true 3. A notification is in flight and waiting to be read by userspace. binder_ref_freeze.sent is false. 4. A notification was read by userspace and kernel is waiting for an ack. binder_ref_freeze.sent is true. When a notification is in flight, new state change events are coalesced into the existing binder_ref_freeze struct. If userspace hasn't picked up the notification yet, the driver simply rewrites the state. Otherwise, the notification is flagged as requiring a resend, which will be performed once userspace acks the original notification that's inflight. See https://r.android.com/3070045 for how userspace is going to use this feature.

Resources allocated with __free are automatically released at the end of the scope. This enhancement aims to mitigate memory management issues associated with forgetting to release resources by utilizing __free instead of of_node_put(). To introduce this feature, some modifications to the code structure were necessary. The original pattern: ``` prev = np; while(...) { [...] np = of_find_next_cache_node(np); of_node_put(prev); prev = np; [...] } ``` has been updated to: ``` while(...) { [...] struct device_node __free(device_node) *prev = np; np = of_find_next_cache_node(np) [...] } ``` With this change, the previous node is automatically cleaned up at the end of each iteration, allowing the elimination of all of_node_put() calls and some goto statements.

This causes heavy locking contention when higher no. of WRs are to be handled inside timeout handler. This leads to softlockup with below trace in some use cases where rdma-cm path is used to establish connection between peer nodes Trace: ----- BUG: soft lockup - CPU#4 stuck for 26s!

The BlinkM LED is a programmable RGB LED. The driver currently supports only the regular LED sysfs class, resulting in the creation of three distinct classes, one for red, green, and blue. The user then has to input three values into the three seperate brightness files within those classes. The multicolor LED framework makes the device easier to control with the multi_intensity file: the user can input three values at once to form a color, while still controlling the lightness with the brightness file. The main struct blinkm_led has changed slightly. The struct led_classdev for the regular sysfs classes remain. The blinkm_probe function checks CONFIG_LEDS_BLINKM_MULTICOLOR to decide whether to load the seperate sysfs classes or the single multicolor one, but never both. The blinkm_set_mc_brightness() function had to be added to calculate the three color components and then set the fields of the blinkm_data structure accordingly.

Add the missing call to `fwnode_handle_get(child)`. The cleanup process where `child` is accessed is not right either because a single call to `fwnode_handle_put()` is carried out in case of an error, ignoring unasigned nodes at the point when the error happens. Keep `child` inside of the first loop, and use the helper pointer that receives references via `fwnode_handle_get()` to handle the child nodes within the second loop. Moreover, the iterated nodes are direct children of the device node, and the `device_for_each_child_node()` macro accounts for child node availability. By restricting `child` to live within that loop, the scoped version of it can be used to simplify the error handling. `fwnode_for_each_available_child_node()` is meant to access the child nodes of an fwnode, and therefore not direct child nodes of the device node. Use `device_for_each_child_node_scoped()` to indicate device's direct child nodes.

This is necessary because for any operation other than temperature, multiple reads need to take place from the device. Even though regmap has a locking by itself, it won't protect us from multiple applications trying to read at the same time temperature and pressure since the pressure reading includes an internal temperature reading and there is nothing to ensure that this temperature+pressure reading will happen sequentially without any other operation interfering in the meantime.

So the bme680_read_{press/humid}() functions of the above sensors are internally calling the equivalent bme680_read_temp() function in order to update the t_fine value. By just looking at the code this relation is a bit hidden and is not easy to understand why those channels are not independent. This commit tries to clear these thing a bit by splitting the bme680_{read/compensate}_{temp/press/humid}() to the following: i. bme680_read_{temp/press/humid}_adc(): read the raw value from the sensor. ii. bme680_calc_t_fine(): calculate the t_fine variable. iii. bme680_get_t_fine(): get the t_fine variable. iv. bme680_compensate_{temp/press/humid}(): compensate the adc values and return the calculated value. v. bme680_read_{temp/press/humid}(): combine calls of the aforementioned functions to return the requested value.

It was replaced by a new variant BU27034ANUC (note, added 'A'). The new variant gained a few significant changes, like removal of the 3.rd data channel and dropping some of the gain settings. This means that, from software point of view these ICs are incompatible. Lux calculation based on the data from the sensors needs to be done differently, and on the BU27034ANUC the channel 3 data is missing. Also, the gain setting differencies matter. Unfortunately, the identification register was not changed so there is no safe way for the software to distinguish the variants. According to the ROHM HQ engineers, the old BU27034NUC should not be encountered in the wild. Hence it makes sense to remove the support for the old BU27034NUC and add support for the new BU27034ANUC. Change the compatible in order to not load the incompatible old driver for new sensor (or, if someone had the old sensor, the new driver for it). Drop the compatible for old sensor which should not be in the wild and add a new compatible for the new model with accurate model suffix 'anuc'. Rename the file to match the new compatible.

The result from these channels is combined into Lux value while the raw channel values are reported via intensity channels. Both of the intensity channels have adjustable gain setting which impacts the scale of the raw channels. Eg, doubling the gain will double the values read from the raw channels, which halves the scale value. The integration time can also be set for the sensor. This does also have an impact to the scale of the intensity channels because increasing the integration time will also increase the values reported via the raw channels. Impact of integration time to the scale and the fact that the scale value does not start from '1', can make it hard for a human reader to compute the gain values based on the scale. Add read-only HARDWAREGAIN to help debugging.

Can be used for triggered buffers as well. Even though it is not a good design choice to have SCALE, RAW and PROCESSED together, the PROCESSED channel is kept for ABI compatibility. While at it, separate BMPxxx and BMExxx device channels since BME supports also humidity measurements.

The ADXL380 supports the +/-4 g, +/-8 g, and +/-16 g ranges, and the ADXL382 supports +/-15 g, +/-30 g and +/-60 g ranges. The ADXL380/ADXL382 offers industry leading noise, enabling precision applications with minimal calibration. The low noise, and low power ADXL380/ADXL382 enables accurate measurement in an environment with high vibration, heart sounds and audio. In addition to its low power consumption, the ADXL380/ADXL382 has many features to enable true system level performance. These include a built-in micropower temperature sensor, single / double / triple tap detection and a state machine to prevent a false triggering. In addition, the ADXL380/ADXL382 has provisions for external control of the sampling time and/or an external clock.

If ``refio-supply`` is present, +then the external reference is used, else the internal reference is used. + +Oversampling and resolution boost +--------------------------------- + +This family supports 2 types of oversampling: normal average and rolling +average. Only normal average is supported by the driver, as rolling average can +be achieved by processing a captured data buffer. The following ratios are +available: 1 (oversampling disabled)/2/4/8/16/32. + +When the on-chip oversampling function is enabled the performance of the ADC can +exceed the default resolution. To accommodate the performance boost achievable, +it is possible to enable an additional two bits of resolution. Because the +resolution boost feature can only be enabled when oversampling is enabled and +oversampling is not as useful without the resolution boost, the driver +automatically enables the resolution boost if and only if oversampling is +enabled. + +Since the resolution boost feature causes 16-bit chips to now have 18-bit data +which means the storagebits has to change from 16 to 32 bits, we use the new +ext_scan_type feature to allow changing the scan_type at runtime.

The device tree will look like this: + +.. code-block:: + + channel@0 { + reg = <0>; /* IN0 */ + }; + +If no other channel properties are needed (e.g. ``adi,no-high-z``), the channel +node can be omitted entirely. + +This will appear on the IIO bus as the ``voltage0`` channel. The processed value +(*raw × scale*) will be the voltage present on the ``IN0`` pin relative to +``REFGND``. (Offset is always 0 when pairing with ``REFGND``.) + +Pairing with COM +^^^^^^^^^^^^^^^^ + +Each ``INx`` pin can be used as a pseudo-differential input in conjunction with +the ``COM`` pin. The device tree will look like this: + +.. code-block:: + + com-supply = <&vref_div_2>; + + channel@1 { + reg = <1>; /* IN1 */ + common-mode-channel = ; + bipolar; + }; + +This will appear on the IIO bus as the ``voltage1`` channel.

The driver looks at the device tree to +determine which is being used. If ``ldo-supply`` is present, then the internal +LDO is used. If ``vcc-supply`` is present, then the external LDO is used and +the internal LDO is disabled. + +Reference voltage +----------------- + +The chip supports an external reference voltage via the ``REF`` input or an +internal buffered reference voltage via the ``REFIN`` input. The driver looks +at the device tree to determine which is being used. If ``ref-supply`` is +present, then the external reference voltage is used and the internal buffer is +disabled.

Either a crystal can be attached externally between MCLK1 and MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2 pin. The other 2 modes make use of the 4.92MHz internal clock. Undocumented properties adi,int-clock-output-enable and adi,clock-xtal still supported for backward compatibility, but their use is highly discouraged. Use cleaner alternative of configuring external clock by using clock names mclk and xtal. Functionality of AD7192_CLK_INT_CO will be implemented in complementary patch by adding clock provider.

The error message is slightly changed since there are fewer error return paths. Setting adc->vref_mv is consolidated into a single place to make the logic easier to follow. A use_internal_vref_attr local variable is added to make it more obvious what the difference between the two iio info structures is.

These parts have a 2:1 multiplexer in front of each ADC. They also include additional configuration registers that allow for either manual selection or automatic switching (sequencer mode), of the multiplexer inputs. This commit focus on integrating manual selection. Sequencer mode will be implemented later. >From an IIO point of view, all inputs are exported, i.e ad7386/7/8 export 4 channels and ad7386-4/7-4/8-4 export 8 channels. Inputs AinX0 of multiplexers correspond to the first half of IIO channels (i.e 0-1 or 0-3) and inputs AinX1 correspond to second half (i.e 2-3 or 4-7).

According to the datasheet, data is valid on the third CS low. We already have an extra toggle before each read (either direct reads or buffered reads) to sample correct data, so we just add a single CS toggle at the end of the register write.

First inputs of muxes correspond to the first half of IIO channels (i.e 0-1 or 0-3) and second inputs correspond to second half (i.e 2-3 or 4-7) Currently, the driver supports only sampling first half OR second half of the IIO channels. To enable sampling all channels simultaneously, these parts have an internal sequencer that automatically cycles through the mux entries. When enabled, the maximum throughput is divided by two. Moreover, the ADCs need additional settling time, so we add an extra CS toggle to correctly propagate setting, and an additional spi transfer to read the second half.

However because of incorrect annotations in device tree marking reset line as active high whereas in reality it is active low, the end result was that the chip was never reset on probe. With polarity of the reset line now corrected this became a problem. Fix this by calling tsc200x_reset() from tsc200x_probe() to properly complete the reset sequence and move requesting the reset GPIO and VIO supply closer to the point where we need to start talking to the hardware.

Also in ti_iodelay_pinconf_init_dev(), if an error occurs after the first regmap_update_bits() call, it is also likely that the deinit() function should be called.

Note that this assumes that the byte after the Vendor ID is a vendor-specific opcode. This flag makes it easier to wait for replies to vendor commands, using the same CEC framework support for waiting for regular replies. Support for this flag is indicated by setting the new CEC_CAP_REPLY_VENDOR_ID capability.

This only mandates that the device-tree sub-nodes used to represent the configuration should describe links with at-most two different protocols. The existing implementation however imposes an artificial constraint that allows only two links (device-tree sub-nodes). As long as at-most two protocols are chosen, using more than two links to describe them in an alternating configuration is still a valid configuration of the Torrent SERDES. A 3-Link 2-Protocol configuration of the 4-Lane SERDES can be: Lane 0 => Protocol 1 => Link 1 Lane 1 => Protocol 1 => Link 1 Lane 2 => Protocol 2 => Link 2 Lane 3 => Protocol 1 => Link 3 A 4-Link 2-Protocol configuration of the 4-Lane SERDES can be: Lane 0 => Protocol 1 => Link 1 Lane 1 => Protocol 2 => Link 2 Lane 2 => Protocol 1 => Link 3 Lane 3 => Protocol 2 => Link 4 Signed-off-by: Siddharth Vadapalli Reviewed-by: Roger Quadros Link: https://lore.kernel.org/r/20240805092607.143869-1-s-vadapalli@ti.com Signed-off-by: Vinod Koul --- drivers/phy/cadence/phy-cadence-torrent.c | 297 +++++++++++++--------- 1 file changed, 175 insertions(+), 122 deletions(-) diff --git a/drivers/phy/cadence/phy-cadence-torrent.c b/drivers/phy/cadence/phy-cadence-torrent.c index a2d32d5f6b07..8bbbbb87bb22 100644 --- a/drivers/phy/cadence/phy-cadence-torrent.c +++ b/drivers/phy/cadence/phy-cadence-torrent.c @@ -351,6 +351,7 @@ struct cdns_torrent_phy { void __iomem *sd_base; /* SD0801 registers base */ u32 max_bit_rate; /* Maximum link bit rate to use (in Mbps) */ u32 dp_pll; + u32 protocol_bitmask; struct reset_control *phy_rst; struct reset_control *apb_rst; struct device *dev; @@ -2473,156 +2474,206 @@ int cdns_torrent_phy_configure_multilink(struct cdns_torrent_phy *cdns_phy) enum cdns_torrent_phy_type phy_t1, phy_t2; const struct cdns_reg_pairs *reg_pairs; int i, j, node, mlane, num_lanes, ret; + struct device *dev = cdns_phy->dev; enum cdns_torrent_ssc_mode ssc; struct regmap *regmap; - u32 num_regs; + u32 num_regs, num_protocols, protocol; - /* Maximum 2 links (subnodes) are supported */ - if (cdns_phy->nsubnodes != 2) + num_protocols = hweight32(cdns_phy->protocol_bitmask); + /* Maximum 2 protocols are supported */ + if (num_protocols > 2) { + dev_err(dev, "at most 2 protocols are supported\n"); return -EINVAL; + } - phy_t1 = cdns_phy->phys[0].phy_type; - phy_t2 = cdns_phy->phys[1].phy_type; /** - * First configure the PHY for first link with phy_t1.

Move the call to devm_pm_runtime_enable() before devm_phy_create() to enable runtime PM at PHY core level. With this change the ->power_on() and ->power_off() callbacks do not require explicit runtime PM management anymore, since the PHY core handles that via phy_pm_runtime_{get,put}_sync() when phy_power_on() and phy_power_off() are invoked. Hence drop the now unnecessary calls to pm_runtime_resume_and_get() and pm_runtime_put() helpers.

However, there are some issues with this approach. There exists a significant performance difference between traditional UFS and zone UFS. Under normal usage, we prioritize writes to zone UFS. However, in critical conditions (such as when the entire UFS is almost full), we cannot determine whether data will be written to traditional UFS or zone UFS. This can lead to significant performance fluctuations, which is not conducive to development and testing. To address this, we have added an option zlu_io_enable under sys with the following three modes: 1) zlu_io_enable == 0:Normal mode, prioritize writing to zone UFS; 2) zlu_io_enable == 1:Zone UFS only mode, only allow writing to zone UFS; 3) zlu_io_enable == 2:Traditional UFS priority mode, prioritize writing to traditional UFS.

The MODULE_FIRMWARE declaration in the base xhci-pci module causes initramfs-tools to check for and warn about missing firmware for the Renesas xHCI controllers, when any xHCI PCI controller is present. And because of the previous oddity, simply moving this declaration to xhci-pci-renesas wouldn't help. To fix this, reverse the relationship between the modules: - Remove the quirk for the Renesas xHCIs, and the driver_data structure used only for them - In xhci-pci: - Rename xhci_pci_probe() to xhci_pci_common_probe() - Export xhci_pci_common_probe() and xhci_pci_remove() - Use a new probe function that rejects the Renesas xHCIs and then calls the common probe function - In xhci-pci-renesas: - Stop exporting renesas_xhci_check_request_fw() - Add a probe function that calls renesas_xhci_check_request_fw() followed by xhci_pci_common_probe() - Add and register a new pci_driver matching only the Renesas xHCIs and using its own probe function, but with other operations the same as in xhci-pci - Make CONFIG_USB_XHCI_PCI_RENESAS depend on CONFIG_USB_XHCI_PCI, not the other way around Finally, move the MODULE_FIRMWARE declaration to xhci-pci-renesas.

It added one to uart_shutdown(), so the commit assumes, uport can be NULL in there. But right after that protection, there is an unprotected "uart_port_dtr_rts(uport, false);" call. That is invoked only if HUPCL is set, so I assume that is the reason why we do not see lots of these reports. Or it cannot be NULL at this point at all for some reason :P. Until the above is investigated, stay on the safe side and move this dereference to the if too. I got this inconsistency from Coverity under CID 1585130. Thanks.

These MUXes can select between OSCCLK or the PLL's output, essentially making the PLL bypassable. These weren't modeled in the driver because the vendor provided drivers didn't model it properly, instead setting them when updating the PMS values. Not having them modeled didn't cause any problems in this case, since these MUXes were set to the PLL's output by default, but this is not the case everywhere in this SoC.

This is an invalid use of use_count though as use_count pertains to the number of times a video entity has been opened by user-space not the number of active streams. If use_count and stream-on count don't agree then stop_streaming() will break as is currently the case and has become apparent when using CAMSS with libcamera's released softisp 0.3. The use of use_count like this is a bit hacky and right now breaks regular usage of CAMSS for a single stream case.

Either way refusing to release video buffers based on use_count is erroneous and should be reverted. The silicon enabling code for selecting VCs is perfectly fine. Its a "known missing feature" that concurrent VCs won't work with CAMSS right now. Initial testing with this code didn't show an error but, SoftISP and "real" usage with Google Hangouts breaks the upstream code pretty quickly, we need to do a partial revert and take another pass at VCs.

The logic in pci_bus_restore_locked() does not take into account that after restoring a device on one level, there might be another Link Downstream that can only start to come up after restore has been performed for its Downstream Port device. That is, the Link may require additional wait until it becomes accessible. Similarly, pci_slot_restore_locked() lacks wait. Amend pci_bus_restore_locked() and pci_slot_restore_locked() to wait for the Secondary Bus before recursively performing the restore of that bus.

The channel phandles are provided in DT through io-channels property and channel indexes through st,adc-channels property. New binding: DFSDM is an IIO channel provider. The channel indexes are given by reg property in channel child node. This new binding is intended to be used with SD modulator IIO backends. It does not support SD modulator legacy IIO devices.

This implementation is not convenient when the SD modulator has to be cascaded with another IIO device. The scaling information is distributed across devices, which makes it difficult to report consistent scaling data on IIO devices. The solution is to expose these cascaded IIO devices as an aggregate device, which report global scaling information. Add IIO backend support to SD modulator to allow scaling information management.

Additionally, remove all usage of nlmsg_parse_depricate(). Strict parsing validation fails when encountering unrecognized attributes in the Netlink message, while liberal parsing validation ignores them. In 57d7a8fd904c ("rdma: Add an option to display driver-specific QPs in the rdma tool") in iproute2, the attribute RDMA_NLDEV_ATTR_DRIVER_DETAILS was added. This cause backwards compatibility issues when using the rdma tool with the new attribute and an older kernel which does recognize this attribute. In this case, the command "rdma stat show mr" would fail, because the new rdma tool would fill the netlink message with the new attribute and the older kernel would fail as it used strict parsing and did not recognize the new attribute. In general, strict validation is appropriate for set commands as they modify the system, while liberal validation is suitable for get commands which only query system information. Replace all uses of nlmsg_parse_deprecated() with __nlmsg_parse(), using the NL_VALIDATE_LIBERAL flag. The nlmsg_parse_deprecated() function internally calls __nlmsg_parse() with the NL_VALIDATE_LIBERAL flag, but its name is confusing.

The 'data direct' driver functions as the affiliated DMA device for one or more capable mlx5_ib devices. This DMA device, as the name suggests, is used exclusively for DMA operations. It can be considered a DMA engine managed by a PF/VF, lacking network capabilities and having minimal overall capabilities. Consequently, the DMA NIC PF will not be exposed to or directly used by software applications. The driver will not have any direct interface or interaction with the firmware (no command interface, no capabilities, etc.). It will operate solely over PCI to enable its DMA functionality. Registration and un-registration of the driver are handled as part of the mlx5_ib initialization and exit processes, as the mlx5_ib devices will effectively be its clients. The driver will serve as the DMA device for accessing another PCI device to achieve optimal performance (both on the same NUMA node, P2P access, etc.). Upon probing, it will read its VUID over PCI to handle mlx5_ib device registrations with the same VUID. Upon removal, it will notify its clients to allow them to clean up the resources that were mmaped with its DMA device.

Upon userspace calling to register a DMABUF MR with the data direct bit set, the below algorithm will be followed. 1) Obtain a pinned DMABUF umem from the IB core using the user input parameters (FD, offset, length) and the DMA PF device. The DMA PF device is needed to allow the IOMMU to enable the DMA PF to access the user buffer over PCI. 2) Create a KSM MKEY by setting its entries according to the user buffer VA to IOVA mapping, with the MKEY being the data direct device-crossed MKEY. This KSM MKEY is umrable and will be used as part of the MR cache. The PD for creating it is the internal device 'data direct' kernel one. 3) Create a crossing MKEY that points to the KSM MKEY using the crossing access mode. 4) Manage the KSM MKEY by adding it to a list of 'data direct' MKEYs managed on the mlx5_ib device. 5) Return the crossing MKEY to the user, created with its supplied PD. Upon DMA PF unbind flow, the driver will revoke the KSM entries. The final deregistration will occur under the hood once the application deregisters its MKEY. Notes: - This version supports only the PINNED UMEM mode, so there is no dependency on ODP. - The IOVA supplied by the application must be system page aligned due to HW translations of KSM. - The crossing MKEY will not be umrable or part of the MR cache, as we cannot change its crossed (i.e. KSM) MKEY over UMR.

As of kernel v6.0, IDR has been superseded by XArray and deprecated. This commit replaces the usage of IDR with XArray to maintain the device instances. The instance of XArray is allocated statically, and initialized with XA_FLAGS_ALLOC so that the index of allocated entry starts with zero and available as the minor identifier of device node.

As the members of the structure are part of the userspace API, the structure layout is immutable and cannot be extended further. Introducing new parameters or modifying the existing ones would change the buffer layout and cause breakages in existing applications. The allow for future extensions to the ISP parameters, introduce a new extensible parameters format, with a new format 4CC. Document usage of the new format in the rkisp1 admin guide.

As the parameters buffer is mapped in the userspace process memory, applications have access to the buffer content after the buffer has been queued. To prevent userspace from modifying the contents of the parameters buffer after it has been queued to the video device, add to 'struct rkisp1_params_buffer' a scratch buffer where to copy the parameters. Allocate the scratch buffer in the vb2 buf_init() operation and copy the buffer content in the buf_prepare() operation.

The usage of the "fixed" format is assumed when allocating memory for the scratch buffers and when initializing the vb2 queue. In order to prepare to support the "extensible" format beside the existing "fixed" one, add support in the driver for both formats by caching a pointer to the active one in the driver structure and use it in the vb2 queue operations and subdev pad operations implementations. Do not yet allow userspace to select between the two formats as the support for the "extensible" format parsing will be introduced in a later patch in the series.

Additional change: - Add ref to /schemas/spi/spi-peripheral-props.yaml - Add #gpio-cell - Remove spi-cpol and spi-cpha in example, the place hold 'spi' can't correct detect spi-controler.yaml. So these two properties can't be recongnized.

This is useful for debugging both interaction with remote processors and client driver issues, as well as tracking latency through the communication stack. Channel events are traced with both local and remote channel ids, as well as the textual representation when possible. The channel ids are useful when matching traces with traces from the firmware side logs, while the textual representation is necessary to identify channels when we're starting to trace an already running system.

As of kernel v6.0, IDR has been superseded by XArray and deprecated. This commit replaces the usage of IDR with XArray to maintain the resource instances. The instance of XArray is allocated per client with XA_FLAGS_ALLOC1 so that the index of allocated entry is greater than zero and returns to user space client as handle of the resource.

For any changes of struct fd representation we need to turn existing accesses to fields into calls of wrappers. Accesses to struct fd::flags are very few (3 in linux/file.h, 1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in explicit initializers). Those can be dealt with in the commit converting to new layout; accesses to struct fd::file are too many for that. This commit converts (almost) all of f.file to fd_file(f). It's not entirely mechanical ('file' is used as a member name more than just in struct fd) and it does not even attempt to distinguish the uses in pointer context from those in boolean context; the latter will be eventually turned into a separate helper (fd_empty()). NOTE: mass conversion to fd_empty(), tempting as it might be, is a bad idea; better do that piecewise in commit that convert from fdget...() to CLASS(...).

The emptiness check is that file reference is NULL, while fdput() is "fput() if FDPUT_FPUT is present in flags". The reason why fdput() on empty instance is a no-op is something compiler can't see - it's that we never generate instances with NULL file reference combined with non-zero flags. It's not that hard to deal with - the real primitives behind fdget() et.al. are returning an unsigned long value, unpacked by (inlined) __to_fd() into the current struct file * + int. The lower bits are used to store flags, while the rest encodes the pointer. Linus suggested that keeping this unsigned long around with the extractions done by inlined accessors should generate a sane code and that turns out to be the case. Namely, turning struct fd into a struct-wrapped unsinged long, with fd_empty(f) => unlikely(f.word == 0) fd_file(f) => (struct file *)(f.word & ~3) fdput(f) => if (f.word & 1) fput(fd_file(f)) ends up with compiler doing the right thing. The cost is the patch footprint, of course - we need to switch f.file to fd_file(f) all over the tree, and it's not doable with simple search and replace; there are false positives, etc. Note that the sole member of that structure is an opaque unsigned long - all accesses should be done via wrappers and I don't want to use a name that would invite manual casts to file pointers, etc. The value of that member is equal either to (unsigned long)p | flags, p being an address of some struct file instance, or to 0 for an empty fd. For now the new predicate (fd_empty(f)) has no users; all the existing checks have form (!fd_file(f)). We will convert to fd_empty() use later; here we only define it (and tell the compiler that it's unlikely to return true). This commit only deals with representation change; there will be followups.

The reason is that the initial state of the port is 'toggling', which causes _max_tcpci_irq() to only drive the contamination part of the TCPM state machine (via tcpm_port_clean()). What should happen instead is that if no contamination was detected, the TCPM should be notified of the CC change in this case. To fix this, we update ...is_contaminant() to also allow its caller to determine if more CC processing is required and then call into the TCPM as required. While at it, add a kernel-doc for max_contaminant_is_contaminant(). Note: the code has an issue where I2C errors during contaminant detection also cause the TCPM state machine to not be updated. This commit doesn't change this behaviour and should be addressed by follow-up commit(s).

We need to rely on polling to detect USB attach events for the dual-role port. The otg state machine implementation is based on Texas Instruments DA8xx/OMAP-L1x glue layer. This has been tested on BeagleV-Fire with couple of devices in host mode and with the Ethernet gadget driver in peripheral mode, in a wide variety of plug orders.

[1] This patch allows implementation of DFU in userspace using the FFS gadget. The DFU protocol uses the control pipe (ep0) for all messaging so only the addition of the DFU functional descriptor is needed in the kernel driver. The DFU functional descriptor is written to the ep0 file along with any other descriptors during FFS setup. DFU requires an interface descriptor followed by the DFU functional descriptor. This patch includes documentation of the added descriptor for DFU and conversion of some existing documentation to kernel-doc format so that it can be included in the generated docs. An implementation of DFU 1.1 that implements just the runtime descriptor using the FunctionFS gadget (with rebooting into u-boot for DFU mode) has been tested on an i.MX8 Nano. An implementation of DFU 1.1 that implements both runtime and DFU mode using the FunctionFS gadget has been tested on Xilinx Zynq UltraScale+. Note that for the best performance of firmware update file transfers, the userspace program should respond as quick as possible to the setup packets.

Calling conventions for __bpf_map_get() would be more convenient if it left fpdut() on failure to callers. Makes for simpler logics in the callers. Among other things, the proof of memory safety no longer has to rely upon file->private_data never being ERR_PTR(...) for bpffs files. Original calling conventions made it impossible for the caller to tell whether __bpf_map_get() has returned ERR_PTR(-EINVAL) because it has found the file not be a bpf map one (in which case it would've done fdput()) or because it found that ERR_PTR(-EINVAL) in file->private_data of a bpf map file (in which case fdput() would _not_ have been done).

charset=UTF-8 Content-Transfer-Encoding: 8bit Recent mgb4 firmwares have support for setting a variable framerate independent of the signal framerate. Add/fix (the mgb4 driver already did promote V4L2_CAP_TIMEPERFRAME, but it didn't work) support for V4L2_CAP_TIMEPERFRAME to the driver to enable this feature. Additionally add support for the DV timings API (VIDIOC_G_DV_TIMINGS, VIDIOC_ENUM_DV_TIMINGS, ...) for the outputs that was missing. The timings info is required/used for implementing the V4L2_CAP_TIMEPERFRAME functionality.

STM32 RTC is now registered as a clock provider. It provides rtc_lsco clock, that means RTC_LSCO is output on either RTC_OUT1 or RTC_OUT2_RMP, depending on pinmux DT property. The clock is marked as CLK_IGNORE_UNUSED and CLK_IS_CRITICAL because RTC_LSCO can be early required by devices needed it to init. Add LSCO in pinmux functions. Add "stm32_rtc_clean_outs" to disable LSCO. As RTC is part of "backup" power domain, it is not reset during shutdown or reboot. So force LSCO disable at probe.

Create a list of handlers for each ISP block that wraps the existing configuration functions and handles the ISP block enablement. Parse the configuration parameters buffer in rkisp1_ext_params_config and filter the enable blocks by group, to allow setting the 'other' groups separately from the 'lsc' group to support the pre/post-configure operations. Implement parameter buffer validation for the extensible format at .buf_prepare() time.

Commit c550e25bca660ed2554cbb48d32b82d0bb98e4b1 ("f2fs: use flush command instead of FUA for zoned device") used additional flush command to keep write order. Since Commit dd291d77cc90eb6a86e9860ba8e6e38eebd57d12 ("block: Introduce zone write plugging") has enabled the block layer to handle this order issue, there is no need to use flush command.

As a final step to entirely enable the required clock tree for the lpass iommu and audio dsp, add the lpass core/adsp GDSCs. As a side note, it was found out that disabling the lpass core GDSC at any time would cause a system lockup (and reboot): disabling this GDSC will leave the lpass iommu completely unclocked, losing its state entirely - including the secure contexts that have been previously set-up from the bootloader/TrustZone. Losing this IOMMU configuration will trigger a hypervisor fault, which will reboot the system; the only workaround for this issue is to declare the lpass core gdsc as always-on. It should also not be forgotten that this is all about firmware and there may be a version of it that doesn't enable this GDSC at all before booting Linux, which is the reason why this specific declaration wasn't simply omitted.

The NoCs are turned on and set to a specific frequency at boot time and that is used for the lifetime of the system. Hence interconnect was not considered previously. The same approach was used for PCIe and at that point the consensus was to move to interconnect. Hence implemented the ICC driver and updating the existing USB driver to use the ICC driver. USB uses icc-clk framework to enable the NoC interface clock. Hence the 'iface' clock is removed from the list of clocks. Update the clock-names list accordingly.

Add the missing call to `fwnode_handle_get(child)`. The cleanup process where `child` is accessed is not right either because a single call to `fwnode_handle_put()` is carried out in case of an error, ignoring unasigned nodes at the point when the error happens. Keep `child` inside of the first loop, and use the helper pointer that receives references via `fwnode_handle_get()` to handle the child nodes within the second loop. Keeping `child` inside the first node has also the advantage that the scoped version of the loop can be used.

This patch adds a defensive programming check on the actual status reported in PING frames. If for some reason an interrupt was lost or delayed, the delayed work would detect a peripheral change of status after the bus starts. The 100ms defined for the delay is not completely arbitrary, if a Peripheral didn't join the bus within that delay then probably the hardware link is broken, and conversely if the detection didn't happen because of software issues the 100ms is still acceptable in terms of user experience. The overhead of the one-shot workqueue is minimal, and the mutual exclusion ensures that the interrupt and delayed work cannot update the status concurrently.

The problem with this sequence is that it might be pre-empted, giving SoundWire devices time to sync and report as ATTACHED before the interrupts are enabled. In that case, the Cadence IP will not detect a state change and will not throw an interrupt to proceed with the enumeration of a Device0. In our overnight stress tests, we observed that a slight sub-millisecond delay in enabling interrupts after the reset was correlated with detection failures. This problem is more prevalent on the LunarLake silicon, likely due to SOC integration changes, but it was observed on earlier generations as well. This patch reverts the sequence, with the interrupts enabled before performing the bus reset. This removes the race condition and makes sure the Cadence IP is able to detect the presence of a Device0 in all cases.

The main reason for that, was that the trait itself returned a `Pin`. The `Arc` implementation of the kernel is already implicitly pinned. To enable `Arc` to implement `InPlaceInit` and to have uniform access, for in-place and pinned in-place initialization, an associated type is introduced for `InPlaceInit`. The new implementation of `InPlaceInit` for `Arc` sets `Arc` as the associated type. Older implementations use an explicit `Pin` as the associated type. The implemented methods for `Arc` are mostly moved from a direct implementation on `Arc`. There should be no user impact. The implementation for `ListArc` is omitted, because it is not merged yet.

This was the combination that worked. We've been carrying this patch in the Asahi tree for a year now. And while Fedora does not currently have GCC plugins enabled because it caused issues with some third-party modules (I think it was the NVIDIA driver, but I'm not sure), it was around long enough for me to know with some confidence that it was fine this way. - Miguel ] Signed-off-by: Neal Gompa Link: https://lore.kernel.org/r/20240731125615.3368813-1-neal@gompa.dev Signed-off-by: Miguel Ojeda --- init/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/init/Kconfig b/init/Kconfig index 5783a0b87517..839c83034006 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -1900,7 +1900,7 @@ config RUST depends on RUST_IS_AVAILABLE depends on !CFI_CLANG depends on !MODVERSIONS - depends on !GCC_PLUGINS + depends on !GCC_PLUGIN_RANDSTRUCT depends on !RANDSTRUCT depends on !SHADOW_CALL_STACK depends on !DEBUG_INFO_BTF || PAHOLE_HAS_LANG_EXCLUDE From 876346536c1b59a5b1b5e44477b1b3ece77647fd Mon Sep 17 00:00:00 2001 From: Andreas Hindborg Date: Thu, 15 Aug 2024 10:30:26 +0000 Subject: [PATCH 0851/2648] rust: kbuild: split up helpers.c This patch splits up the rust helpers C file.

The existing target feature being enabled was a leftover from our old `rust` branch, and it is not enough: the target feature `retpoline-external-thunk` only implies `retpoline-indirect-calls`, but not `retpoline-indirect-branches` (see LLVM's `X86.td`), unlike Clang's flag of the same name `-mretpoline-external-thunk` which does imply both (see Clang's `lib/Driver/ToolChains/Arch/X86.cpp`). Without this, `objtool` would complain if enabled for Rust, e.g.: rust/core.o: warning: objtool: _R...escape_default+0x13: indirect jump found in RETPOLINE build In addition, change the comment to note that LLVM is the one disabling jump tables when retpoline is enabled, thus we do not need to use `-Zno-jump-tables` for Rust here -- see commit c58f2166ab39 ("Introduce the "retpoline" x86 mitigation technique ...") [1]: The goal is simple: avoid generating code which contains an indirect branch that could have its prediction poisoned by an attacker. In many cases, the compiler can simply use directed conditional branches and a small search tree. LLVM already has support for lowering switches in this way and the first step of this patch is to disable jump-table lowering of switches and introduce a pass to rewrite explicit indirectbr sequences into a switch over integers. As well as a live example at [2]. These should be eventually enabled via `-Ctarget-feature` when `rustc` starts recognizing them (or via a new dedicated flag) [3].

Without this, `objtool` would complain if enabled for Rust, e.g.: rust/core.o: warning: objtool: _R...9panic_fmt() falls through to next function _R...18panic_nounwind_fmt() rust/alloc.o: warning: objtool: .text: unexpected end of section In order to do so, we cannot match symbols' names exactly, for two reasons: - Rust mangling scheme [1] contains disambiguators [2] which we cannot predict (e.g. they may vary depending on the compiler version). One possibility to solve this would be to parse v0 and ignore/zero those before comparison. - Some of the diverging functions come from `core`, i.e. the Rust standard library, which may change with each compiler version since they are implementation details (e.g. `panic_internals`). Thus, to workaround both issues, only part of the symbols are matched, instead of using the `NORETURN` macro in `noreturns.h`. Ideally, just like for the C side, we should have a better solution. For instance, the compiler could give us the list via something like: $ rustc --emit=noreturns ... [ Kees agrees this should be automated and Peter says: So it would be fairly simple to make objtool consume a magic section emitted by the compiler.. I think we've asked the compiler folks for that at some point even, but I don't have clear recollections. We will ask upstream Rust about it. And if they agree, then perhaps we can get Clang/GCC to implement something similar too -- for this sort of thing we can take advantage of the shorter cycles of `rustc` as well as their unstable features concept to experiment. Gary proposed using DWARF (though it would need to be available), and wrote a proof of concept script using the `object` and `gimli` crates: https://gist.github.com/nbdd0121/449692570622c2f46a29ad9f47c3379a - Miguel ] Link: https://rust-lang.github.io/rfcs/2603-rust-symbol-name-mangling-v0.html [1] Link: https://doc.rust-lang.org/rustc/symbol-mangling/v0.html#disambiguator [2] Acked-by: Peter Zijlstra (Intel) Tested-by: Alice Ryhl Reviewed-by: Kees Cook Tested-by: Benno Lossin Link: https://lore.kernel.org/r/20240725183325.122827-6-ojeda@kernel.org [ Added `len_mismatch_fail` symbol for new `kernel` crate code merged since then as well as 3 more `core::panicking` symbols that appear in `RUST_DEBUG_ASSERTIONS=y` builds. - Miguel ] Signed-off-by: Miguel Ojeda --- tools/objtool/check.c | 52 ++++++++++++++++++++++++++++++++++++++- tools/objtool/noreturns.h | 2 ++ 2 files changed, 53 insertions(+), 1 deletion(-) diff --git a/tools/objtool/check.c b/tools/objtool/check.c index 01237d167223..d086f207a3d3 100644 --- a/tools/objtool/check.c +++ b/tools/objtool/check.c @@ -177,6 +177,52 @@ static bool is_sibling_call(struct instruction *insn) return (is_static_jump(insn) && insn_call_dest(insn)); } +/* + * Checks if a string ends with another. + */ +static bool str_ends_with(const char *s, const char *sub) +{ + const int slen = strlen(s); + const int sublen = strlen(sub); + + if (sublen > slen) + return 0; + + return !memcmp(s + slen - sublen, sub, sublen); +} + +/* + * Checks if a function is a Rust "noreturn" one. + */ +static bool is_rust_noreturn(const struct symbol *func) +{ + /* + * If it does not start with "_R", then it is not a Rust symbol. + */ + if (strncmp(func->name, "_R", 2)) + return false; + + /* + * These are just heuristics -- we do not control the precise symbol + * name, due to the crate disambiguators (which depend on the compiler) + * as well as changes to the source code itself between versions (since + * these come from the Rust standard library). + */ + return str_ends_with(func->name, "_4core5sliceSp15copy_from_slice17len_mismatch_fail") || + str_ends_with(func->name, "_4core6option13unwrap_failed") || + str_ends_with(func->name, "_4core6result13unwrap_failed") || + str_ends_with(func->name, "_4core9panicking5panic") || + str_ends_with(func->name, "_4core9panicking9panic_fmt") || + str_ends_with(func->name, "_4core9panicking14panic_explicit") || + str_ends_with(func->name, "_4core9panicking14panic_nounwind") || + str_ends_with(func->name, "_4core9panicking18panic_bounds_check") || + str_ends_with(func->name, "_4core9panicking19assert_failed_inner") || + str_ends_with(func->name, "_4core9panicking36panic_misaligned_pointer_dereference") || + strstr(func->name, "_4core9panicking11panic_const24panic_const_") || + (strstr(func->name, "_4core5slice5index24slice_") && + str_ends_with(func->name, "_fail")); +} + /* * This checks to see if the given function is a "noreturn" function. * @@ -202,10 +248,14 @@ static bool __dead_end_function(struct objtool_file *file, struct symbol *func, if (!func) return false; - if (func->bind == STB_GLOBAL || func->bind == STB_WEAK) + if (func->bind == STB_GLOBAL || func->bind == STB_WEAK) { + if (is_rust_noreturn(func)) + return true; + for (i = 0; i < ARRAY_SIZE(global_noreturns); i++) if (!strcmp(func->name, global_noreturns[i])) return true; + } if (func->bind == STB_WEAK) return false; diff --git a/tools/objtool/noreturns.h b/tools/objtool/noreturns.h index 1e8141ef1b15..e7da92489167 100644 --- a/tools/objtool/noreturns.h +++ b/tools/objtool/noreturns.h @@ -39,6 +39,8 @@ NORETURN(panic) NORETURN(panic_smp_self_stop) NORETURN(rest_init) NORETURN(rewind_stack_and_make_dead) +NORETURN(rust_begin_unwind) +NORETURN(rust_helper_BUG) NORETURN(sev_es_terminate) NORETURN(snp_abort) NORETURN(start_kernel) From c4d7f546dd9aa9780716cdb07416ca97264dce43 Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Thu, 25 Jul 2024 20:33:23 +0200 Subject: [PATCH 0857/2648] objtool/kbuild/rust: enable objtool for Rust Now that we should be `objtool`-warning free, enable `objtool` for Rust too.

Then, the tree of device is sought to find the previous data of fw_device corresponding to the node. If found, the previous data is updated and reused and the data of fw_device newly allocated is going to be released. The above procedure is done in the call of device_find_child(), however it is a bit abusing against the intention of the helper function, since it is preferable to find only without updating. This commit splits the update outside of the call.

Each sink owns its own trace ID map, and any Perf session connecting to that sink will allocate from it, even if the sink is currently in use by other users. This is similar to the existing behavior where the dynamic trace IDs are constant as long as there is any concurrent Perf session active. It's not completely optimal because slightly more IDs will be used than necessary, but the optimal solution involves tracking the PIDs of each session and allocating ID maps based on the session owner. This is difficult to do with the combination of per-thread and per-cpu modes and some scheduling issues. The complexity of this isn't likely to worth it because even with multiple users they'd just see a difference in the ordering of ID allocations rather than hitting any limits (unless the hardware does have too many ETMs connected to one sink).

Perf may have finished while sysfs hadn't, and Perf shouldn't release the IDs in use by sysfs and vice versa. Now that Perf uses its own exclusive ID maps, pending release doesn't result in any different behavior than just releasing all IDs when the last Perf session finishes. As part of the per-sink trace ID change, we would have still had to make the pending mechanism work on a per-sink basis, due to the overlapping ID allocations, so instead of making that more complicated, just remove it.

In particular, it is currently able to use `__must_check` in C (`#[must_use]` in Rust), which give us a bunch of annotations that are nice to have to prevent possible issues in Rust abstractions, e.g.: extern "C" { + #[must_use] pub fn kobject_add( kobj: *mut kobject, parent: *mut kobject, fmt: *const core::ffi::c_char, ... ) -> core::ffi::c_int; } Apparently, there are edge cases where this can make generation very slow, which is why it is behind a flag [1], but it does not seem to affect us in any major way at the moment.

There are scenarios where LSMs want to deny a process the ability to write particular files, even files that the FSUID of the process owns; but this can currently partially be bypassed using atomic write ioctls in two ways: - F2FS_IOC_START_ATOMIC_REPLACE + F2FS_IOC_COMMIT_ATOMIC_WRITE can truncate an inode to size 0 - F2FS_IOC_START_ATOMIC_WRITE + F2FS_IOC_ABORT_ATOMIC_WRITE can revert changes another process concurrently made to a file Fix it by requiring FMODE_WRITE for these operations, just like for F2FS_IOC_MOVE_RANGE. Since any legitimate caller should only be using these ioctls when intending to write into the file, that seems unlikely to break anything.

This check works well for most cases, but it does not work for conventional zones on zoned block devices. F2fs assumes that zoned block devices support discard, and calls __submit_discard_cmd(). When __submit_discard_cmd() is called for sequential write required zones, it works fine since __submit_discard_cmd() issues zone reset commands instead of discard commands. However, when __submit_discard_cmd() is called for conventional zones, __blkdev_issue_discard() is called even when the devices do not support discard. The inappropriate __blkdev_issue_discard() call was not a problem before the commit 30f1e7241422 ("block: move discard checks into the ioctl handler") because __blkdev_issue_discard() checked if the target devices support discard or not. If not, it returned EOPNOTSUPP. After the commit, __blkdev_issue_discard() no longer checks it. It always returns zero and sets NULL to the given bio pointer. This NULL pointer triggers f2fs_bug_on() in __submit_discard_cmd(). The BUG is recreated with the commands below at the umount step, where /dev/nullb0 is a zoned null_blk with 5GB total size, 128MB zone size and 10 conventional zones. $ mkfs.f2fs -f -m /dev/nullb0 $ mount /dev/nullb0 /mnt $ for ((i=0;i<5;i++)); do dd if=/dev/zero of=/mnt/test bs=65536 count=1600 conv=fsync; done $ umount /mnt To fix the BUG, avoid the inappropriate __blkdev_issue_discard() call. When discard is requested for conventional zones, check if the device supports discard or not. If not, return EOPNOTSUPP.

For wrapped key HMAC algorithms, the key size is independent of the cryptographic key size. So there is no known size of the mac key in such cases. The desired key size can optionally be specified as argument when the dm-crypt device is configured via 'integrity_key_size:%u'. If no integrity_key_size argument is specified, the mac key size is still set to the digest size, as before. Increase version number to 1.28.0 so that support for the new argument can be detected by user space (i.e. cryptsetup).

This core is typically used for safety applications in a stand alone mode. However, some application (non safety related) may want to use the M4F core as a generic remote processor with IPC to the host processor. The M4F core has internal IRAM and DRAM memories and are exposed to the system bus for code and data loading. A remote processor driver is added to support this subsystem, including being able to load and boot the M4F core. Loading includes to M4F internal memories and predefined external code/data memories. The carve outs for external contiguous memory is defined in the M4F device node and should match with the external memory declarations in the M4F image binary. The M4F subsystem has two resets. One reset is for the entire subsystem i.e including the internal memories and the other, a local reset is only for the M4F processing core. When loading the image, the driver first releases the subsystem reset, loads the firmware image and then releases the local reset to let the M4F processing core run.

This was happening due to some scheduling between prepare and start callback. The probe function waits for event, which is getting triggered by prepare callback. To avoid above condition move event trigger to start instead of prepare callback.

Below is a minimalistic example how this can be used. Note these values are just examples. The exact values in practice depend on host specific capabilities and the type of measurement to be performed. # cd /sys/kernel/debug/thunderbolt/ROUTER/portX/margining/ # echo software > mode # echo 400 > dwell_time # echo 1 > run As usual the results attribute contains the results of a succesfull run.

However, some USB Hosts will request the contents of feature reports via the GET_REPORT request. In addition, some proprietary HID 'protocols' will expect different data, for the same report ID, to be to become available in the feature report by sending a preceding SET_REPORT to the USB Device that defines what data is to be presented when that feature report is subsequently retrieved via GET_REPORT (with a very fast < 5ms turn around between the SET_REPORT and the GET_REPORT). There are two other patch sets already submitted for adding GET_REPORT support. The first [1] allows for pre-priming a list of reports via IOCTLs which then allows the USB Host to perform the request, with no further userspace interaction possible during the GET_REPORT request. And another [2] which allows for a single report to be setup by userspace via IOCTL, which will be fetched and returned by the kernel for subsequent GET_REPORT requests by the USB Host, also with no further userspace interaction possible. This patch, while loosely based on both the patch sets, differs by allowing the option for userspace to respond to each GET_REPORT request by setting up a poll to notify userspace that a new GET_REPORT request has arrived. To support this, two extra IOCTLs are supplied. The first of which is used to retrieve the report ID of the GET_REPORT request (in the case of having non-zero report IDs in the HID descriptor). The second IOCTL allows for storing report responses in a list for responding to requests. The report responses are stored in a list (it will be either added if it does not exist or updated if it exists already). A flag (userspace_req) can be set to whether subsequent requests notify userspace or not. Basic operation when a GET_REPORT request arrives from USB Host: - If the report ID exists in the list and it is set for immediate return (i.e. userspace_req == false) then response is sent immediately, userspace is not notified - The report ID does not exist, or exists but is set to notify userspace (i.e. userspace_req == true) then notify userspace via poll: - If userspace responds, and either adds or update the response in the list and respond to the host with the contents - If userspace does not respond within the fixed timeout (2500ms) but the report has been set prevously, then send 'old' report contents - If userspace does not respond within the fixed timeout (2500ms) and the report does not exist in the list then send an empty report Note that userspace could 'prime' the report list at any other time. While this patch allows for flexibility in how the system responds to requests, and therefore the HID 'protocols' that could be supported, a drawback is the time it takes to service the requests and therefore the maximum throughput that would be achievable. The USB HID Specification v1.11 itself states that GET_REPORT is not intended for periodic data polling, so this limitation is not severe. Testing on an iMX8M Nano Ultra Lite with a heavy multi-core CPU loading showed that userspace can typically respond to the GET_REPORT request within 1200ms - which is well within the 5000ms most operating systems seem to allow, and within the 2500ms set by this patch.

Hardware IRQ numbers start at 0, and we register PCI_NUM_INTX IRQs. So to enable INTA (aka hwirq 0) we should set bit 0. Remove the subtraction of one. This bug would cause INTx interrupts not to be delivered, as enabling INTB would actually enable INTA, and enabling INTA wouldn't enable anything at all. It is likely that this got overlooked for so long since most PCIe hardware uses MSIs.

By ensuring that each object has only one `ListArc` reference, the owner of that reference is assured exclusive access to the `next`/`prev` pointers. When a `ListArc` is inserted into a `List`, the `List` takes ownership of the `ListArc` reference. There are various strategies for ensuring that a value has only one `ListArc` reference. The simplest is to convert a `UniqueArc` into a `ListArc`. However, the refcounted object could also keep track of whether a `ListArc` exists using a boolean, which could allow for the creation of new `ListArc` references from an `Arc` reference. Whatever strategy is used, the relevant tracking is referred to as "the tracking inside `T`", and the `ListArcSafe` trait (and its subtraits) are used to update the tracking when a `ListArc` is created or destroyed. Note that we allow the case where the tracking inside `T` thinks that a `ListArc` exists, but actually, there isn't a `ListArc`. However, we do not allow the opposite situation where a `ListArc` exists, but the tracking thinks it doesn't. This is because the former can at most result in us failing to create a `ListArc` when the operation could succeed, whereas the latter can result in the creation of two `ListArc` references. Only the latter situation can lead to memory safety issues. This patch introduces the `impl_list_arc_safe!` macro that allows you to implement `ListArcSafe` for types using the strategy where a `ListArc` can only be created from a `UniqueArc`. Other strategies are introduced in later patches. This is part of the linked list that Rust Binder will use for many different things. The strategy where a `ListArc` can only be created from a `UniqueArc` is actually sufficient for most of the objects that Rust Binder needs to insert into linked lists. Usually, these are todo items that are created and then immediately inserted into a queue. The const generic ID allows objects to have several prev/next pointer pairs so that the same object can be inserted into several different lists. You are able to have several `ListArc` references as long as they correspond to different pointer pairs. The ID itself is purely a compile-time concept and will not be present in the final binary. Both the `List` and the `ListArc` will need to agree on the ID for them to work together. Rust Binder uses this in a few places (e.g. death recipients) where the same object can be inserted into both generic todo lists and some other lists for tracking the status of the object. The ID is a const generic rather than a type parameter because the `pair_from_unique` method needs to be able to assert that the two ids are different. There's no easy way to assert that when using types instead of integers.

The `impl_list_arc_safe!` macro is extended with a `tracked_by` strategy that defers the tracking of ListArcs to a field of the struct. Additionally, the AtomicListArcTracker type is introduced, which can track whether a ListArc exists using an atomic. By deferring the tracking to a field of type AtomicListArcTracker, structs gain the ability to create ListArcs without going through a UniqueArc. Rust Binder uses this for some objects where we want to be able to insert them into a linked list at any time. Using the AtomicListArcTracker, we are able to check whether an item is already in the list, and if not, we can create a `ListArc` and push it. The macro has the ability to defer the tracking of ListArcs to a field, using whatever strategy that field has. Since we don't add any strategies other than AtomicListArcTracker, another similar option would be to hard-code that the field should be an AtomicListArcTracker. However, Rust Binder has a case where the AtomicListArcTracker is not stored directly in the struct, but in a sub-struct. Furthermore, the outer struct is generic: struct Wrapper { links: ListLinks, inner: T, } Here, the Wrapper struct implements ListArcSafe with `tracked_by inner`, and then the various types used with `inner` also uses the macro to implement ListArcSafe. Some of them use the untracked strategy, and some of them use tracked_by with an AtomicListArcTracker. This way, Wrapper just inherits whichever choice `inner` has made.

Also define the ListItem trait, which is implemented by structs that have a ListLinks field. The ListItem trait provides four different methods that are all essentially container_of or the reverse of container_of. Two of them are used before inserting/after removing an item from the list, and the two others are used when looking at a value without changing whether it is in a list. This distinction is introduced because it is needed for the patch that adds support for heterogeneous lists, which are implemented by adding a third pointer field with a fat pointer to the full struct. When inserting into the heterogeneous list, the pointer-to-self is updated to have the right vtable, and the container_of operation is implemented by just returning that pointer instead of using the real container_of operation.

The linked list uses the following design: The List type itself just has a single pointer to the first element of the list. And the actual list items then form a cycle. So the last item is `first->prev`. This is slightly different from the usual kernel linked list. Matching that exactly would amount to giving List two pointers, and having it be part of the cycle of items. This alternate design has the advantage that the cycle is never completely empty, which can reduce the number of branches in some cases. However, it also has the disadvantage that List must be pinned, which this design is trying to avoid. Having the list items form a cycle rather than having null pointers at the beginning/end is convenient for several reasons. For one, it lets us store only one pointer in List, and it simplifies the implementation of several functions. Unfortunately, the `remove` function that removes an arbitrary element from the list has to be unsafe. This is needed because there is no way to handle the case where you pass an element from the wrong list. For example, if it is the first element of some other list, then that other list's `first` pointer would not be updated. Similarly, it could be a data race if you try to remove it from two different lists in parallel. (There's no problem with passing `remove` an item that's not in any list. Additionally, other removal methods such as `pop_front` need not be unsafe, as they can't be used to remove items from another list.) A future patch in this series will introduce support for cursors that can be used to remove arbitrary items without unsafe code.

This feature cannot be added to the iterator because the references you get from the iterator are considered borrows of the original list, rather than borrows of the iterator. This means that there's no way to prevent code like this: let item = iter.next(); iter.remove(); use(item); If `iter` was a cursor instead of an iterator, then `item` will be considered a borrow of `iter`. Since `remove` destroys `iter`, this means that the borrow-checker will prevent uses of `item` after the call to `remove`. So there is a trade-off between supporting use in traditional for loops, and supporting removal of elements as you iterate. Iterators and cursors represents two different choices on that spectrum. Rust Binder needs cursors for the list of death notifications that a process is currently handling. When userspace tells Binder that it has finished processing the death notification, Binder will iterate the list to search for the relevant item and remove it.

This is generally done using trait objects. The main challenge is figuring what the struct is given only a pointer to the ListLinks. We do this by storing a pointer to the struct next to the ListLinks field. The container_of operation will then just read that pointer. When the type is a trait object, that pointer will be a fat pointer whose metadata is a vtable that tells you what kind of struct it is. Heterogeneous lists are heavily used by Rust Binder. There are a lot of so-called todo lists containing various events that need to be delivered to userspace next time userspace calls into the driver. And there are quite a few different todo item types: incoming transaction, changes to refcounts, death notifications, and more.

The feature of having a special reference to a refcounted object with exclusive access to specific fields is useful for other things, so provide a general utility for that. This is used by Rust Binder to keep track of which processes have a reference to a given node. This involves an object for each process/node pair, that is referenced by both the process and the node. For some fields in this object, only the process's reference needs to access them (and it needs mutable access), so Binder uses a ListArc to give the process's reference exclusive access.

Jul 2024 14:24:59 -0700 Subject: [PATCH 1011/2648] leds: gpio: Set num_leds after allocation With the new __counted_by annotation, the "num_leds" variable needs to valid for accesses to the "leds" array. This requirement is not met in gpio_leds_create(), since "num_leds" starts at "0", so "leds" index "0" will not be considered valid (num_leds would need to be "1" to access index "0"). Fix this by setting the allocation size after allocation, and then update the final count based on how many were actually added to the array.

The datasheets for the SoCs have small nuances around the Pre-Clip registers ELPrC and EPPrC in three use-cases, interlaced images, embedded data and RAW8 input. On V4H the values written to the registers are based on odd numbers while on V4M they are even numbers, values are based on the input image size. No board that uses these SoCs which also have the external peripherals to test these nuances exists. Most likely this is an issue in the datasheet. Before adding bindings for V4M add a family compatible fallback for Gen4. That way the driver only needs to be updated once for Gen4, and we still have the option to fix any problems in the driver if any testable differences between the SoCs are found. There are already DTS files using the V3U and V4H compatibles which need to be updated to not produce a warning for DTS checks. The driver also needs to keep the compatible values to be backward compatible , but for new Gen4 SoCs such as V4M we can avoid this.

The combined usage of pm_sleep_ptr() and LATE_SYSTEM_SLEEP_PM_OPS() allows the compiler to evaluate if the runtime suspend/resume() functions are used at build time or are simply dead code. This allows removing the __maybe_unused notation from the runtime suspend/resume() functions.

Currently, the driver is working on the assumption that an I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using MEDIA_BUS_FMT as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data() and simplifly probe() and mt9p031_init_state(). While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.

It is the inverse operation of `ARef::from_raw`, and allows you to convert the `ARef` back into a raw pointer while retaining ownership of the refcount. This new function will be used by [1] for converting the type in an `ARef` using `ARef::from_raw(ARef::into_raw(me).cast())`. Alice has also needed the same function for other use-cases in the past, but [1] is the first to go upstream. This was implemented independently by Kartik and Alice. The two versions were merged by Alice, so all mistakes are Alice's.

In addition, introduce the "Rust code documentation" term, which may be clearer than referring to a potentially unknown tool. Furthermore, for the HTML case, homogenize both `rustdoc` and non-`rustdoc` cases and use the term introduced above instead. Then, always generate the pregenerated version part, since now there is a section that is always generated and thus makes sense to do so. Finally, finish the new section with a link to more details about the Rust code documentation. The intention is that: - The non-HTML case mentions the code documentation too, making it more prominent for readers of non-HTML docs. - Both HTML cases read more naturally. - The pregenerated version is always mentioned, since it is likely useful for readers of non-HTML docs.

It adds links to the source view of the documentation. For instance, in the source view of `rust/kernel/sync.rs`, for this code: impl Default for LockClassKey { fn default() -> Self { Self::new() } } It will add three hyperlinks: - `Default` points to the rendered "Trait `core::default::Default`" page (not the source view, since it goes to another crate, though this may change). - `LockClassKey` points to the `pub struct LockClassKey(...);` line in the same page, highlighting the line number. - `Self::new()` points to the `pub const fn new() -> Self { ... }` associated function, highlighting its line numbers (i.e. for the full function). This makes the source view more useful and a bit closer to the experience in e.g. the Elixir Cross Referencer [3]. I have provisionally enabled it for rust.docs.kernel.org [4] -- one can take a look at the source view there for an example of how it looks like. Thus enable it.

Subject: [PATCH 1107/2648] pinctrl: sophgo: add support for CV1800B SoC Sophgo CV1800 series SoCs share common control logic but have different register mapping. For maintenance, split the driver and pin definition of the SoC. Add base driver for CV1800 series SoC and pin definition of CV1800B.

This can happen if driver supports auto-detection, but certain devices are also instantiated explicitly. The original change isn't actually wrong, it just revealed that I2C core isn't prepared yet to handle this scenario. Calls to i2c_new_client_device() can be nested, therefore we can't use a simple mutex here. Parallel instantiation of devices at different addresses is ok, so we just have to prevent parallel instantiation at the same address. We can use a bitmap with one bit per 7-bit I2C client address, and atomic bit operations to set/check/clear bits. Now a parallel attempt to instantiate a device at the same address will result in -EBUSY being returned, avoiding the "sysfs: cannot create duplicate filename" splash. Note: This patch version includes small cosmetic changes to the Tested-by version, only functional change is that address locking is supported for slave addresses too.

The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core USB serial code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register").

When called on a link whose sink is a video device, it only prints a warning and returns. As the microchip-isc driver implements manual validate of the subdev to video device link, we can just drop the v4l2_subdev_link_validate() to avoid the warning.

As links get validated in the context of their sink, a call to the helper when the link's sink is not a subdev indicates that the driver has set its .link_validate() handler to v4l2_subdev_link_validate() on a non-subdev entity, which is a clear driver bug. On the other hand, the link's source not being a subdev indicates that the helper is used for a subdev connected to a video output device, which is a lesser issue, if only because this is currently common practice. There are no drivers left in the kernel that use v4l2_subdev_link_validate() in a context where it may get called on a non-subdev sink. Replace the pr_warn_once() with a WARN_ON_ONCE() in this case to make sure that new offenders won't be introduced. A subsequent change will improve the v4l2_subdev_link_validate() helper to properly support validating video device to subdev links.

It supports subdev-to-subdev links only, and complains if one end of the link is not a subdev. This forces drivers that have video output devices connected to subdevs to implement a custom .link_validate() handler, calling v4l2_subdev_link_validate() for the subdev-to-subdev links, and performing manual link validation for the video-to-subdev links. Video devices embed a media entity, and therefore also have a .link_validate() operation. For video capture devices, the operation should be manually implemented by drivers for validate the subdev-to-video links. For video output devices, on the other hand, that operation is never called, as link validation is performed in the context of the sink entity. As a result, we end up forcing drivers to implement a custom .link_validate() handler for subdevs connected to video output devices, when the video devices provide an operation that could be used for that purpose. To improve that situation, make v4l2_subdev_link_validate() delegate link validation to the source's .link_validate() operation when the link source is a video device and the link sink is a subdev. This allows broader usage of v4l2_subdev_link_validate(), and simplifies drivers by making video device link validation easy to implement in the video device .link_validate(), regardless of whether the video device is an output device or a capture device.

Typically Linux needs to send a message to the remote core and requests for poweroff or reboot. By default the communication between Linux core and the remote core is is done via a blocking mailbox mechanism but Linux doesn't allow blocking operations in the system off (reboot, power off) handlers. So, we need to make sure the mailbox message send operations do not block for this specific operations. Fortunately, Linux allows us to register handlers that are called in preparation of the system off operations. Thus, before carrying the power off or reboot preparations, just destroy the existing mailboxes and create them as non-blocking. Note that power off and restart are totally different operations and are not complementary. We introduce a new flag in the imx remoteproc per device data which tells us when a device needs this special setup. For now, only imx7ulp needs it.

It turns out this breaks the Renesas R-Car VSP test suite, where a test that allocates a single buffer fails when two buffers are used. One may consider debatable whether test suite failures without failures in production use cases should be considered as a regression, but operation with a single buffer is a valid use case. While full frame rate can't be maintained, memory-to-memory devices can still be used with a decent efficiency, and requiring applications to allocate multiple buffers for single-shot use cases with capture devices would just waste memory. For those reasons, fix the regression by dropping the global minimum of buffers. Individual drivers can still set their own minimum.

In other words, if the device gets attached to an hwpt_nested directly, the parent hwpt_paging of the hwpt_nested's would not enforce those reserved IOVAs. This works for most of reserved region types, but not for IOMMU_RESV_SW_MSI, which is a unique software defined window, required by a nesting case too to setup an MSI doorbell on the parent stage-2 hwpt/domain. Kevin pointed out in 1 that: 1) there is no usage using up closely the entire IOVA space yet, 2) guest may change the viommu mode to switch between nested and paging then VMM has to take all devices' reserved regions into consideration anyway, when composing the GPA space. So it would be actually convenient for us to also enforce reserved IOVA onto the parent hwpt_paging, when attaching a device to an hwpt_nested. Repurpose the existing attach/replace_paging helpers to attach device's reserved IOVAs exclusively. Add a new find_hwpt_paging helper, which is only used by these reserved IOVA functions, to allow an IOMMUFD_OBJ_HWPT_NESTED hwpt to redirect to its parent hwpt_paging. Return a NULL in these two helpers for any new HWPT type in the future.

The impact of compressed frames is confirmed when using perf to monitor the number of memory accesses with or without the compression feature. The following command: perf stat -a -e \ imx8_ddr0/cycles/,imx8_ddr0/read-cycles/,imx8_ddr0/write-cycles/ \ gst-launch-1.0 filesrc \ location=Jockey_3840x2160_120fps_420_8bit_HEVC_RAW.hevc ! queue ! \ h265parse ! v4l2slh265dec ! video/x-raw,format=NV12 ! fakesink Gives us these results without the compression feature: Performance counter stats for 'system wide': 1711300345 imx8_ddr0/cycles/ 892207924 imx8_ddr0/read-cycles/ 1291785864 imx8_ddr0/write-cycles/ 13.760048353 seconds time elapsed With the compression feature: Performance counter stats for 'system wide': 274526799 imx8_ddr0/cycles/ 453120194 imx8_ddr0/read-cycles/ 833391434 imx8_ddr0/write-cycles/ 18.257831534 seconds time elapsed As expected the number of read/write cycles are really lower when compression is used. Since storing the compression data requires more memory a module parameter named 'hevc_use_compression' is used to enable/disable this feature and, by default, compression isn't used. Enabling the compression feature means that the output-frames of the decoder are stored with a specific compression pixel-format. Since this pixel format is unknown, this patch restrains the compression feature usage to the cases where post-processor pixel-formats (NV12 or NV15) are selected by the applications. The Fluster compliance HEVC test suite score is still 141/147 with this patch.

Previously, I/O configuration was limited by software to partial GPIO support only. When working in a pure gpio mode, the device does not require the certain properties and hence, the following are now made optional: - interrupts - keypad,num-rows - keypad,num-columns - linux,keymap However, note that the above are required to be specified when configuring the device as a keypad, for which dependencies have been added such that specifying either one requires the remaining as well. Also, note that interrupts are made optional, but required when the device has either been configured in keypad mode or as an interrupt controller. This has been done since they may not necessarily be used when leveraging the device purely for GPIO.

[PATCH 1204/2648] fuse: cleanup request queuing towards virtiofs Virtiofs has its own queuing mechanism, but still requests are first queued on fiq->pending to be immediately dequeued and queued onto the virtio queue. The queuing on fiq->pending is unnecessary and might even have some performance impact due to being a contention point. Forget requests are handled similarly. Move the queuing of requests and forgets into the fiq->ops->*. fuse_iqueue_ops are renamed to reflect the new semantics.

And there is no need to check fi->writepages with spin_lock, which may have an impact on performance due to lock contention.

As the register that need to be touched for this is in the address space of the USB PHY, and the UBS PHY need to be initialized before any other USB drivers handling data transfer, add support to initialize the USB BUS. As the USB PHY is probed before any other USB drivers that enables clocks and de-assert the reset signals and the BUS initialization is done in the probe phase, we need to add code to de-assert reset signal and runtime resume the device (which enables its clocks) before accessing the registers. As the reset signals are not required by the USB PHY driver for the other USB PHY hardware variants, the reset signals and runtime PM was handled only in the function that initialize the USB BUS. The PHY initialization was done right after runtime PM enable to have all in place when the PHYs are registered.

Right now we use a usleep_rage() that gives a sleep time of between about 430 and 860 microseconds. On the Lenovo X13s we have observed that in about 1/20 cases the current timing is too tight and we start transacting before the ov5675's reset cycle completes, leading to I2C bus transaction failures. The reset racing is sometimes triggered at initial chip probe but, more usually on a subsequent power-off/power-on cycle e.g. [ 71.451662] ov5675 24-0010: failed to write reg 0x0103. error = -5 [ 71.451686] ov5675 24-0010: failed to set plls The current quiescence period we have is too tight. Instead of expressing the post reset delay in terms of the current XVCLK this patch converts the power-on and power-off delays to the maximum theoretical delay @ 6 MHz with an additional buffer. 1.365 milliseconds on the power-on path is 1.5 milliseconds with grace. 85.3 microseconds on the power-off path is 90 microseconds with grace.

Set the reset-gpio to GPIO_OUT_HIGH at initialization time to make sure it starts off in reset. Also drop the "Set XCLR" comment which is not-so-informative. The existing usage of imx335 had reset-gpios polarity inverted (GPIO_ACTIVE_HIGH) in their device-tree sources. With this patch included, those DTS will not be able to stream imx335 anymore. The reset-gpio polarity will need to be rectified in the device-tree sources as shown in [1] example, in order to get imx335 functional again (as it remains in reset prior to this fix).

Add functions to obtain a cursor to the tree by key: - The node with the smallest key - The node with the largest key - The node matching the given key, or the one with the next larger key The cursor abstraction is needed by the binder driver to efficiently search for nodes and (conditionally) modify them, as well as their neighbors [1].

This API can be used to access the entry at a specific key and make modifications depending on whether the key is vacant or occupied. This API is useful because it can often be used to avoid traversing the tree multiple times. This is used by binder to look up and conditionally access or insert a value, depending on whether it is there or not [2].

But this domain number could be useful to the EPC drivers to uniquely identify each controller based on the hardware instance when there are multiple ones present in an SoC (even multiple RC/EP). So let's make use of the existing pci_bus_find_domain_nr() API to allocate domain numbers based on either devicetree (linux,pci-domain) property or dynamic domain number allocation scheme. It should be noted that the domain number allocated by this API will be based on both RC and EP controllers in a SoC. If the 'linux,pci-domain' DT property is present, then the domain number represents the actual hardware instance of the PCI endpoint controller. If not, then the domain number will be allocated based on the PCI EP/RC controller probe order. If the architecture doesn't support CONFIG_PCI_DOMAINS_GENERIC (rare), then currently a warning is thrown to indicate that the architecture specific implementation is needed.

So when an endpoint is attached to the SoC, users have to rescan the bus manually to enumerate the device. But this can be avoided by using the Link up event exposed by the Qcom specific 'global_irq' interrupt. Qcom PCIe RC controllers are capable of generating the 'global' SPI interrupt to the host CPUs. The device driver can use this interrupt to identify events such as PCIe link specific events, safety events etc... One such event is the PCIe Link up event generated when an endpoint is detected on the bus and the Link is 'up'. This event can be used to enumerate the PCIe endpoint devices without user intervention. So add support for capturing the PCIe Link up event using the 'global' interrupt in the driver. Once the Link up event is received, the bus underneath the host bridge is scanned to enumerate PCIe endpoint devices. All of the Qcom SoCs have only one Root Port per controller instance. So only a single 'Link up' event is generated for the PCIe controller.

It uses PARF_SLV_ADDR_SPACE_SIZE register to get the size of the memory block to be mirrored and uses PARF_DBI_BASE_ADDR, PARF_ATU_BASE_ADDR registers to determine the base address of DBI and ATU space inside the memory block that is being mirrored. When a memory region which is located above the SLV_ADDR_SPACE_SIZE boundary is used for BAR region then there could be an overlap of DBI and ATU address space that is getting mirrored and the BAR region. This results in DBI and ATU address space contents getting updated when a PCIe function driver tries updating the BAR/MMIO memory region. Reference memory map of the PCIe memory region with DBI and ATU address space overlapping BAR region is as below. |---------------| | | | | ------- --------|---------------| | | |---------------| | | | DBI | | | |---------------|---->DBI_BASE_ADDR | | | | | | | | | PCIe | |---->2*SLV_ADDR_SPACE_SIZE | BAR/MMIO|---------------| | Region | ATU | | | |---------------|---->ATU_BASE_ADDR | | | | PCIe | |---------------| Memory | | DBI | Region | |---------------|---->DBI_BASE_ADDR | | | | | --------| | | | |---->SLV_ADDR_SPACE_SIZE | |---------------| | | ATU | | |---------------|---->ATU_BASE_ADDR | | | | |---------------| | | DBI | | |---------------|---->DBI_BASE_ADDR | | | | | | ----------------|---------------| | | | | | | |---------------| Currently memory region beyond the SLV_ADDR_SPACE_SIZE boundary is not used for BAR region which is why the above mentioned issue is not encountered. This issue is discovered as part of internal testing when we tried moving the BAR region beyond the SLV_ADDR_SPACE_SIZE boundary. Hence we are trying to fix this. As PARF hardware block mirrors DBI and ATU register space after every PARF_SLV_ADDR_SPACE_SIZE (default 0x1000000) boundary multiple, program maximum possible size to this register by writing 0x80000000 to it(it considers only powers of 2 as values) to avoid mirroring DBI and ATU to BAR/MMIO region. Write the physical base address of DBI and ATU register blocks to PARF_DBI_BASE_ADDR (default 0x0) and PARF_ATU_BASE_ADDR (default 0x1000) respectively to make sure DBI and ATU blocks are at expected memory locations. The register offsets PARF_DBI_BASE_ADDR_V2, PARF_SLV_ADDR_SPACE_SIZE_V2 and PARF_ATU_BASE_ADDR are applicable for platforms that use Qcom IP rev 1.9.0, 2.7.0 and 2.9.0. PARF_DBI_BASE_ADDR_V2 and PARF_SLV_ADDR_SPACE_SIZE_V2 are applicable for Qcom IP rev 2.3.3. PARF_DBI_BASE_ADDR and PARF_SLV_ADDR_SPACE_SIZE are applicable for Qcom IP rev 1.0.0, 2.3.2 and 2.4.0. Update init()/post_init() functions of the respective Qcom IP versions to program applicable PARF_DBI_BASE_ADDR, PARF_SLV_ADDR_SPACE_SIZE and PARF_ATU_BASE_ADDR register offsets. Update the SLV_ADDR_SPACE_SZ macro to 0x80000000 to set highest bit in PARF_SLV_ADDR_SPACE_SIZE register. Cache DBI and iATU physical addresses in 'struct dw_pcie' so that pcie_qcom.c driver can program these addresses in the PARF_DBI_BASE_ADDR and PARF_ATU_BASE_ADDR registers.

For example, you can cross-build Debian packages for arm64 by running the following command: $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg However, the generated linux-headers-*_arm64.deb is useless because the host programs in it were built for your build machine architecture (likely x86), not arm64. The Debian kernel maintains its own Makefiles to cross-compile host tools without relying on Kbuild. [1] Instead of adding such full custom Makefiles, this commit adds a small piece of code to cross-compile host programs located under the scripts/ directory. A straightforward solution is to pass HOSTCC=${CROSS_COMPILE}gcc, but it would also cross-compile scripts/basic/fixdep, which needs to be native to process the if_changed_dep macro. (This approach may work under some circumstances; you can execute foreign architecture programs with the help of binfmt_misc because Debian systems enable CONFIG_BINFMT_MISC, but it would require installing QEMU and libc for that architecture.) A trick is to use the external module build (KBUILD_EXTMOD=), which does not rebuild scripts/basic/fixdep. ${CC} needs to be able to link userspace programs (CONFIG_CC_CAN_LINK=y). There are known limitations: - GCC plugins It would possible to rebuild GCC plugins for the target architecture by passing HOSTCXX=${CROSS_COMPILE}g++ with necessary packages installed, but gcc on the installed system emits "cc1: error: incompatible gcc/plugin versions". - objtool and resolve_btfids These are built by the tools build system. They are not covered by the current solution. The resulting linux-headers package is broken if CONFIG_OBJTOOL or CONFIG_DEBUG_INFO_BTF is enabled. I only tested this with Debian, but it should work for other package systems as well.

The commit message didn't give a rationale. Later on, commit 1f5d3a6b6532 ("Remove *.rej pattern from .gitignore") removed the *.rej pattern in v2.6.26, on the rationale that *.rej files indicated something went really wrong and should not be ignored. The *.rej files are now shown by `git status`, which helps located conflicts when applying patches and lowers the probability that they will go unnoticed. It is however still easy to overlook the *.orig files which slowly polute the source tree. That's not as big of a deal as not noticing a conflict, but it's still not nice. Drop the *.orig pattern from .gitignore to avoid this and help keep the source tree clean. Signed-off-by: Laurent Pinchart [masahiroy@kernel.org: I do not have a strong opinion about this. Perhaps some people may have a different opinion. If you are someone who wants to ignore *.orig, it is likely you would want to do so across all projects. Then, $XDG_CONFIG_HOME/git/ignore would be more suitable for your needs. gitignore(5) suggests, "Patterns which a user wants Git to ignore in all situations generally go into a file specified by core.excludesFile in the user's ~/.gitconfig". Please note that you cannot do the opposite; if *.orig is ignored by the project's .gitignore, you cannot override the decision because $XDG_CONFIG_HOME/git/ignore has a lower priority. If *.orig is sitting on the fence, I'd leave it to the users. ] Signed-off-by: Masahiro Yamada --- .gitignore | 1 - 1 file changed, 1 deletion(-) diff --git a/.gitignore b/.gitignore index 7902adf4f7f1..58fdbb35e2f1 100644 --- a/.gitignore +++ b/.gitignore @@ -142,7 +142,6 @@ GTAGS # id-utils files ID -*.orig *~ \#*# From 0c4beffbfe3fcd711b5d9268e7c7d63d4c1cc964 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 4 Aug 2024 12:33:07 +0900 Subject: [PATCH 1364/2648] kbuild: modinst: remove the multithread option from zstd compression Parallel execution is supported by GNU Make: $ make -j modules_install It is questionable to enable multithreading within each zstd process by default.

This leads to its removal from the 'dispose' list! * Now nf->ref is 0, unhashed. nfsd_file_put() continues its execution and set nf->nf_ref to REFCOUNT_SATURATED. As shown in the above analysis, using nf_lru for both the LRU list and dispose list can cause the leaks. This patch adds a new list_head nf_gc in struct nfsd_file, and uses it for the dispose list.

However as sysctl_mount_point is an empty array and does not occupy and space it can end up sharing an address with another object in memory. If that other object itself is a "struct ctl_table" then registering that table will fail as it's incorrectly recognized as permanently empty. Avoid this issue by adding a dummy element to the array so that is not empty anymore. Explicitly register the table with zero elements as otherwise the dummy element would be recognized as a sentinel element which would lead to a runtime warning from the sysctl core. While the issue seems not being encountered at this time, this seems mostly to be due to luck. Also a future change, constifying sysctl_mount_point and root_table, can reliably trigger this issue on clang 18. Given that empty arrays are non-standard in the first place it seems prudent to avoid them if possible.

After entering the crash kernel,before the USB interrupt handler registration was completed while loading the DWC USB driver,an GINTSTS_SOF interrupt was received.This triggered the misroute_irq process within the GIC handling framework,ultimately leading to the misrouting of the interrupt,causing it to be handled by the wrong interrupt handler and resulting in the issue. Summary:In a scenario where the kernel triggers a panic and enters the crash kernel,it is necessary to ensure that the interrupt mask bit is not enabled before the interrupt registration is complete. If an interrupt reaches the CPU at this moment,it will certainly not be handled correctly,especially in cases where this interrupt is reported frequently. Please refer to the Crashkernel dmesg information as follows (the message on line 3 was added before devm_request_irq is called by the dwc2_driver_probe function): [ 5.866837][ T1] dwc2 JMIC0010:01: supply vusb_d not found, using dummy regulator [ 5.874588][ T1] dwc2 JMIC0010:01: supply vusb_a not found, using dummy regulator [ 5.882335][ T1] dwc2 JMIC0010:01: before devm_request_irq irq: [71], gintmsk[0xf300080e], gintsts[0x04200009] [ 5.892686][ C0] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.10.0-jmnd1.2_RC #18 [ 5.900327][ C0] Hardware name: CMSS HyperCard4-25G/HyperCard4-25G, BIOS 1.6.4 Jul 8 2024 [ 5.908836][ C0] Call trace: [ 5.911965][ C0] dump_backtrace+0x0/0x1f0 [ 5.916308][ C0] show_stack+0x20/0x30 [ 5.920304][ C0] dump_stack+0xd8/0x140 [ 5.924387][ C0] pcie_xxx_handler+0x3c/0x1d8 [ 5.930121][ C0] __handle_irq_event_percpu+0x64/0x1e0 [ 5.935506][ C0] handle_irq_event+0x80/0x1d0 [ 5.940109][ C0] try_one_irq+0x138/0x174 [ 5.944365][ C0] misrouted_irq+0x134/0x140 [ 5.948795][ C0] note_interrupt+0x1d0/0x30c [ 5.953311][ C0] handle_irq_event+0x13c/0x1d0 [ 5.958001][ C0] handle_fasteoi_irq+0xd4/0x260 [ 5.962779][ C0] __handle_domain_irq+0x88/0xf0 [ 5.967555][ C0] gic_handle_irq+0x9c/0x2f0 [ 5.971985][ C0] el1_irq+0xb8/0x140 [ 5.975807][ C0] __setup_irq+0x3dc/0x7cc [ 5.980064][ C0] request_threaded_irq+0xf4/0x1b4 [ 5.985015][ C0] devm_request_threaded_irq+0x80/0x100 [ 5.990400][ C0] dwc2_driver_probe+0x1b8/0x6b0 [ 5.995178][ C0] platform_drv_probe+0x5c/0xb0 [ 5.999868][ C0] really_probe+0xf8/0x51c [ 6.004125][ C0] driver_probe_device+0xfc/0x170 [ 6.008989][ C0] device_driver_attach+0xc8/0xd0 [ 6.013853][ C0] __driver_attach+0xe8/0x1b0 [ 6.018369][ C0] bus_for_each_dev+0x7c/0xdc [ 6.022886][ C0] driver_attach+0x2c/0x3c [ 6.027143][ C0] bus_add_driver+0xdc/0x240 [ 6.031573][ C0] driver_register+0x80/0x13c [ 6.036090][ C0] __platform_driver_register+0x50/0x5c [ 6.041476][ C0] dwc2_platform_driver_init+0x24/0x30 [ 6.046774][ C0] do_one_initcall+0x50/0x25c [ 6.051291][ C0] do_initcall_level+0xe4/0xfc [ 6.055894][ C0] do_initcalls+0x80/0xa4 [ 6.060064][ C0] kernel_init_freeable+0x198/0x240 [ 6.065102][ C0] kernel_init+0x1c/0x12c Signed-off-by: Shawn Shao Link: https://lore.kernel.org/r/20240830031709.134-1-shawn.shao@jaguarmicro.com Signed-off-by: Greg Kroah-Hartman --- drivers/usb/dwc2/platform.c | 26 ++++++++++++++------------ 1 file changed, 14 insertions(+), 12 deletions(-) diff --git a/drivers/usb/dwc2/platform.c b/drivers/usb/dwc2/platform.c index 7b84416dfc2b..c1b7209b9483 100644 --- a/drivers/usb/dwc2/platform.c +++ b/drivers/usb/dwc2/platform.c @@ -469,18 +469,6 @@ static int dwc2_driver_probe(struct platform_device *dev) spin_lock_init(&hsotg->lock); - hsotg->irq = platform_get_irq(dev, 0); - if (hsotg->irq < 0) - return hsotg->irq; - - dev_dbg(hsotg->dev, "registering common handler for irq%d\n", - hsotg->irq); - retval = devm_request_irq(hsotg->dev, hsotg->irq, - dwc2_handle_common_intr, IRQF_SHARED, - dev_name(hsotg->dev), hsotg); - if (retval) - return retval; - hsotg->vbus_supply = devm_regulator_get_optional(hsotg->dev, "vbus"); if (IS_ERR(hsotg->vbus_supply)) { retval = PTR_ERR(hsotg->vbus_supply); @@ -524,6 +512,20 @@ static int dwc2_driver_probe(struct platform_device *dev) if (retval) goto error; + hsotg->irq = platform_get_irq(dev, 0); + if (hsotg->irq < 0) { + retval = hsotg->irq; + goto error; + } + + dev_dbg(hsotg->dev, "registering common handler for irq%d\n", + hsotg->irq); + retval = devm_request_irq(hsotg->dev, hsotg->irq, + dwc2_handle_common_intr, IRQF_SHARED, + dev_name(hsotg->dev), hsotg); + if (retval) + goto error; + /* * For OTG cores, set the force mode bits to reflect the value * of dr_mode.

Make the bInterfaceProtocol configurable. For this, track the number of instances and only allow write to the property if there are no intances (yet).

Tunneling capable ports have an ACPI _DSD object pointing to the USB4 Host Interface that is used to establish USB3 3.x tunnels Set the link directly between tunneled USB3 devices and USB4 Host Interface to ensure that the USB4 host can runtime suspend if no tunneled USB 3.x devices exist. Current Thunderbolt code sets a link between USB4 Host Interface and USB3 xHCI host which prevents USB4 Host Interface from runtime suspending even if the USB3 host is only serving native USB devices. See commit b2be2b05cf3b ("thunderbolt: Create device links from ACPI description") for details. As the device link is only set for USB3 devices that are already tunneled we know that USB4 Host Interface exists and is bound to its driver.

Since currently all 9pfs servers lack support for the usb transport this tool is an useful helper to get started.

However, there are a couple codepaths in the kernel where firmware file names contain string components that are passed through from a device or semi-privileged userspace; the ones I could find (not counting interfaces that require root privileges) are: - lpfc_sli4_request_firmware_update() seems to construct the firmware filename from "ModelName", a string that was previously parsed out of some descriptor ("Vital Product Data") in lpfc_fill_vpd() - nfp_net_fw_find() seems to construct a firmware filename from a model name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I think parses some descriptor that was read from the device. (But this case likely isn't exploitable because the format string looks like "netronome/nic_%s", and there shouldn't be any *folders* starting with "netronome/nic_". The previous case was different because there, the "%s" is *at the start* of the format string.) - module_flash_fw_schedule() is reachable from the ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is enough to pass the privilege check), and takes a userspace-provided firmware name. (But I think to reach this case, you need to have CAP_NET_ADMIN over a network namespace that a special kind of ethernet device is mapped into, so I think this is not a viable attack path in practice.) Fix it by rejecting any firmware names containing ".." path components. For what it's worth, I went looking and haven't found any USB device drivers that use the firmware loader dangerously.

Only devices with drivers that have async_shutdown_enable enabled will be shut down asynchronously. This can dramatically reduce system shutdown/reboot time on systems that have multiple devices that take many seconds to shut down (like certain NVMe drives). On one system tested, the shutdown time went from 11 minutes without this patch to 55 seconds with the patch.

These registers are removed from the 8-bit regmap allowable ranges and AD4695_MAX_REG is dropped since it would be ambiguous now. debugfs register access is also updated to automatically use the correct regmap depending on the register address.

He has been active reviewing Rust code in the mailing list, and he already is a formal reviewer of the Rust PHY library and the two PHY drivers. In addition, he is also part of several upstream Rust teams: compiler-contributors team (contributors to the Rust compiler on a regular basis), libs-contributors (contributors to the Rust standard library on a regular basis), crate-maintainers (maintainers of official Rust crates), the binary size working group and the Rust for Linux ping group. His expertise with the language will be very useful to have around in the future if Rust keeps growing within the kernel, thus add him to the `RUST` entry as a reviewer.

With that change, __usb_hcd_giveback_urb now gets executed in the hardirq context, which causes problems for KCOV and KMSAN. One problem is that KCOV now is unable to collect coverage from the USB code that gets executed from the dummy_hcd's timer callback, as KCOV cannot collect coverage in the hardirq context. Another problem is that the dummy_hcd hrtimer might get triggered in the middle of a softirq with KCOV remote coverage collection enabled, and that causes a WARNING in KCOV, as reported by syzbot. (I sent a separate patch to shut down this WARNING, but that doesn't fix the other two issues.) Finally, KMSAN appears to ignore tracking memory copying operations that happen in the hardirq context, which causes false positive kernel-infoleaks, as reported by syzbot. Change the hrtimer in dummy_hcd to execute the callback in the softirq context.

The workqueue is allocated per instance of fw_card structure to satisfy the following characteristics descending from 1394 OHCI specification: In 1394 OHCI specification, memory pages are reserved to each isochronous context dedicated to DMA transmission. It allows to operate these per-context pages concurrently. Software can schedule hardware interrupt for several isochronous context to the same cycle, thus WQ_UNBOUND is specified. Additionally, it is sleepable to operate the content of pages, thus WQ_BH is not used. The isochronous context delivers the packets with time stamp, thus WQ_HIGHPRI is specified for semi real-time data such as IEC 61883-1/6 protocol implemented by ALSA firewire stack. The isochronous context is not used by the implementation of SCSI over IEEE1394 protocol (sbp2), thus WQ_MEM_RECLAIM is not specified. It is useful for users to adjust cpu affinity of the workqueue depending on their work loads, thus WQ_SYS is specified to expose the attributes to user space.

In the case, ALSA PCM device has a flag, nonatomic, to acquire mutex lock instead of spin lock for PCM substream group. This commit uses the flag. It has an advantage in the case that ALSA PCM application uses the large size of intermediate buffer, since it takes too long time even in tasklet softIRQ to process many of isochronous packets, then result in the delay of system event due to disabled IRQ so long. It is avertible to switch to nonatomic operation.

This "static" way works perfecly well for local filesystems like ext4, xfs, btrfs, etc. But for network-like filesystems like fuse, cephfs this approach is not ideal, because sometimes proper support of vfs idmaps requires some extensions for the on-wire protocol, which implies that changes have to be made not only in the Linux kernel code but also in the 3rd party components like libfuse, cephfs MDS server and so on. We have seen that issue during our work on cephfs idmapped mounts [1] with Christian, but right now I'm working on the idmapped mounts support for fuse/virtiofs and I think that it is a right time for this extension.

Difference between these two is that generic_fillattr() takes all the stat() data from the inode directly, while fuse_fillattr() codepath takes a fresh data just from the userspace reply on the FUSE_GETATTR request. In some cases we can just pass &nop_mnt_idmap, because idmapping won't be used in these codepaths. For example, when 3rd argument of fuse_do_getattr() is NULL then idmap argument is not used.

The devicetree for SC7280 now specifies eight interrupts, following the commit b8ba66b40da3 ("arm64: dts: qcom: sc7280: Add additional MSI interrupts"). Thus, update the bindings to reflect this.

ON Semiconductor has an "Advance Information" datasheet available (ENA2222-D.PDF), but no full datasheet. So there is no documentation available for the registers. This driver is based on the register info from the extcon-fsa9285.c driver, from the Lollipop Android sources for the Lenovo Yoga Tablet 2 (Pro) 830 / 1050 / 1380 models. Note despite the name this is actually a driver for the LC824206XA not the FSA9285. This has only been tested on a Lenovo Yoga Tablet 2 Pro 1380 and using the driver on other setups may require additional work. So far this driver is only used on x86/ACPI (non devicetree) devs. Therefor there is no devicetree bindings documentation for this driver's "onnn,enable-miclr-for-dcp" property since this is not used in actual devicetree files and the dt bindings maintainers have requested properties with no actual dt users to _not_ be added to the dt bindings.

NPEM is indication oriented and it does not give direct access to LEDs. Although each indication *could* represent an individual LED, multiple indications could also be represented as a single, multi-color LED or a single LED blinking in a specific interval. The specification leaves that open. Each enabled indication (capability register bit on) is represented as a ledclass_dev which can be controlled through sysfs. For every ledclass device only 2 brightness states are allowed: LED_ON (1) or LED_OFF (0). This corresponds to the NPEM control register (Indication bit on/off). Ledclass devices appear in sysfs as child devices (subdirectory) of PCI device which has an NPEM Extended Capability and indication is enabled in NPEM capability register. For example, these are LEDs created for pcieport "10000:02:05.0" on my setup: leds/ ├── 10000:02:05.0:enclosure:fail ├── 10000:02:05.0:enclosure:locate ├── 10000:02:05.0:enclosure:ok └── 10000:02:05.0:enclosure:rebuild They can be also found in "/sys/class/leds" directory. The parent PCIe device domain/bus/device/function address is used to guarantee uniqueness across leds subsystem. To enable/disable a "fail" indication, the "brightness" file can be edited: echo 1 > ./leds/10000:02:05.0:enclosure:fail/brightness echo 0 > ./leds/10000:02:05.0:enclosure:fail/brightness PCIe r6.1, sec 7.9.19.2 defines the possible indications. Multiple indications for same parent PCIe device can conflict and hardware may update them when processing new request. To avoid issues, driver refresh all indications by reading back control register. This driver expects to be the exclusive NPEM extended capability manager. It waits up to 1 second after imposing new request, it doesn't verify if controller is busy before write, and it assumes the mutex lock gives protection from concurrent updates. If _DSM LED management is available, we assume the platform may be using NPEM for its own purposes (see PCI Firmware Spec r3.3 sec 4.7), so the driver does not use NPEM. A future patch will add _DSM support; an info message notes whether NPEM or _DSM is being used. NPEM is a PCIe extended capability so it should be registered in pcie_init_capabilities() but it is not possible due to LED dependency. The parent pci_device must be added earlier for led_classdev_register() to be successful. NPEM does not require configuration on kernel side, so it is safe to register LED devices later.

An endpoint may halt and xHC DbC triggers a STALL error event if there's an issue with a bulk data transfer. The transfer should restart once xHC DbC receives a ClearFeature(ENDPOINT_HALT) request from the host. Once xHC DbC restarts it will start from the TRB pointed to by dequeue field in the endpoint context, which might be the same TRB we got the STALL event for. Turn the TRB to a no-op in this case to make sure xHC DbC doesn't reuse and tries to retransmit this same TRB after we already handled it, and gave its corresponding data request back. Other STALL events might be completely bogus. Lukasz Bartosik discovered that xHC DbC might issue spurious STALL events if hosts sends a ClearFeature(ENDPOINT_HALT) request to non-halted endpoints even without any active bulk transfers. Assume STALL event is spurious if it reports 0 bytes transferred, and the endpoint stopped on the STALLED TRB. Don't give back the data request corresponding to the TRB in this case. The halted status is per endpoint. Track it with a per endpoint flag instead of the driver invented DbC wide DS_STALLED state. DbC remains in DbC-Configured state even if endpoints halt.

There are not kernel wide rules for these, but for IIO the style that I prefer (and hence most common) is: - Space after { and before } - No comma after terminator { } This may cause merge conflicts but they should be trivial to resolve hence I have not broken this into per driver patches.

The approach taken resembles `pahole`'s -- see commit 613fe1692377 ("kbuild: Add CONFIG_PAHOLE_VERSION"), i.e. a simple version parsing without trying to identify several kinds of compilers, since so far there is only one (`rustc`). However, unlike `pahole`'s, we also print a zero if executing failed for any reason, rather than checking if the command is found and executable (which still leaves things like a file that exists and is executable, but e.g. is built for another platform [1]). An equivalent approach to the one here was also submitted for `pahole` [2].

This also applies to proc macros (which only work with the `rustc` that compiled them), via the already existing dependency on `core.o`. That is cleaned up in the next commit. However, this does not cover host programs written in Rust, which is the same case in the C side. This is accomplished by referencing directly the generated file, instead of using the `fixdep` header trick, since we cannot change the Rust standard library sources. This is not too much of a burden, since it only needs to be done for `core`.

This means that both the `core` and `macros` crates can be built in parallel, and that touching `core.o` does not trigger a rebuild of the proc macros. This could be accomplished using the same approach as for `core` (i.e. depending directly on `include/config/RUSTC_VERSION_TEXT`). However, that is considered an implementation detail [1], and thus it is best to avoid it. Instead, let fixdep find a string that we explicitly write down in the source code for this purpose (like it is done for `include/linux/compiler-version.h`), which we can easily do (unlike for `core`) since this is our own source code.

This mode uses devices with non-power-of-2 sector size. The extra metadata after each sector are used to hold the integrity hash. This commit enhances the inline mode, so that there is automatic recalculation of the integrity hashes when the 'reclaculate' parameter is used. It allows us to activate the device instantly, and the recalculation is done on background. If the device is deactivated while recalculation is in progress, it will remember the point where it stopped and it will continue from this point when activated again.

The design is similar to NPEM defined in PCIe Base Specification r6.1 sec 6.28: - Both standards are indication oriented, - _DSM supported bits correspond to NPEM capability register bits, - _DSM control bits correspond to NPEM control register bits. _DSM does not support enclosure-specific indications or the special NPEM commands NPEM_ENABLE and NPEM_RESET. _DSM is implemented as a second backend in NPEM driver. The backend used is logged with info priority. The same sysfs interface is used for both NPEM and _DSM. According to spec, _DSM has higher priority, and availability of _DSM in not limited to devices with NPEM support. The Dell implementation of DSM uses acpi ipmi, which may not be available immediately (in fact it may take up to 10s for this interface to be available). It can determine if DSM is supported (GET_SUPPORTED_STATES_DSM is working) but it cannot serve GET_STATE_DSM or SET_STATE_DSM commands in this time. From userspace application perspective (primarily configured by systemd service) it is better to have not working but configured interface rather than have it available after few seconds. For that reason, npem->active_indications cache is now loaded lazily, i.e. any GET or SET request want cache to be updated if it is not done yet.

For that a dedicated .mod.c file is generated by modpost for each module and then linked into the module. However most of the information in the .mod.c is the same for all modules, internal and external. Split the shared information into a dedicated source file that is compiled once and then linked into all modules. This avoids frequent rebuilds for all .mod.c files when using CONFIG_LOCALVERSION_AUTO because the local version ends up in .mod.c through UTS_RELEASE and VERMAGIC_STRING. The modules are still relinked in this case. The code is also easier to maintain as it's now in a proper source file instead of an inline string literal.

In existing chips there are three inbound windows with fixed purposes: the first was for mapping SoC internal registers, the second was for memory, and the third was for memory but with the endian swapped. Typically, only one window was used. Complicating the inbound window usage was the fact that the PCIe HW would do a baroque internal mapping of system memory, and concatenate the regions of multiple memory controllers. Newer chips such as the 7712 and Cable Modem SoCs take a step forward and drop the internal mapping while providing for multiple inbound windows. This works in concert with the dma-ranges property, where each provided range becomes an inbound window.

The actual behaviour is different between isochronous receive (IR) and transmit (IT) contexts in respect to isochronous cycle in which the hardIRQ occurs. In IR context, the hardIRQ occurs when the buffer is filled actually by the content of received packet. If there are any isochronous cycles in which the packet transmission is skipped, it is postponed to generate the hardIRQ in respect to the isochronous cycle. In IT context, software can schedule the content of packet every isochronous cycle including skipping, therefore the hardIRQ occurs in the isochronous cycle to which the software scheduled. ALSA firewire stack uses the packet-per-buffer mode for both IR/IT contexts. To process time stamp per packet (or per sample in some cases) steadily for media clock recovery against unexpected transmission skips, it uses an IT context to operate all of isochronous contexts by calls of fw_iso_context_flush_completions() in the bottom-half of hardIRQ for the IT context. Although it looks well to handle all of isochronous contexts in a single bottom-half context, it relatively takes longer time. In the future code integration (not yet), it is possible to apply parallelism method to process these context. In the case, it is useful to allow unit drivers to schedule work items to process these isochronous contexts. As a preparation, this commit exposes fw_iso_context_schedule_flush_completions() as a kernel API available by unit drivers. It is renamed from fw_iso_context_queue_work() since it is a counter part of fw_iso_context_flush_completions().

Works with conventional RCU and SRCU, and possibly other RCU flavors in the future, meaning this can serve as a more generic replacement for SLAB_TYPESAFE_BY_RCU. Pending items are tracked in radix trees; if memory allocation fails, we fall back to linked lists. A rcu_pending is initialized with a callback, which is invoked when pending items's grace periods have expired. Two types of callback processing are handled specially: - RCU_PENDING_KVFREE_FN New backend for kvfree_rcu(). Slightly faster, and eliminates the synchronize_rcu() slowpath in kvfree_rcu_mightsleep() - instead, an rcu_head is allocated if we don't have one and can't use the radix tree TODO: - add a shrinker (as in the existing kvfree_rcu implementation) so that memory reclaim can free expired objects if callback processing isn't keeping up, and to expedite a grace period if we're under memory pressure and too much memory is stranded by RCU - add a counter for amount of memory pending - RCU_PENDING_CALL_RCU_FN Accelerated backend for call_rcu() - pending callbacks are tracked in a radix tree to eliminate linked list overhead. to serve as replacement backends for kvfree_rcu() and call_rcu(); these may be of interest to other uses (e.g. SLAB_TYPESAFE_BY_RCU users). Note: Internally, we're using a single rearming call_rcu() callback for notifications from the core RCU subsystem for notifications when objects are ready to be processed. Ideally we would be getting a callback every time a grace period completes for which we have objects, but that would require multiple rcu_heads in flight, and since the number of gp sequence numbers with uncompleted callbacks is not bounded, we can't do that yet.

It is never cleared by hardware other than by software writing 1 to the bit position in the Link Status register and we never do such a write. We currently have two places, namely apply_bad_link_workaround() and pcie_failed_link_retrain() in drivers/pci/controller/dwc/pcie-tegra194.c and drivers/pci/quirks.c respectively where we check the state of the LBMS bit and neither is interested in the state of the bit resulting from the completion of retraining, both check for a link fault. And in particular pcie_failed_link_retrain() causes issues consequently, by trying to retrain a link where there's no downstream device anymore and the state of 1 in the LBMS bit has been retained from when there was a device downstream that has since been removed. Clear the LBMS bit then at the conclusion of pcie_retrain_link(), so that we have a single place that controls it and that our code can track link speed or width changes resulting from unreliable link operation.

Consequently such a downstream device will suffer from an unnecessary communication throughput limitation and therefore performance loss. Remove the speed restriction then and revert the Link Control 2 register to its original state if link retraining with the speed restriction in place has failed. Retrain the link again afterwards so as to remove any residual state, waiting on LT rather than DLLLA to avoid an excessive delay and ignoring the result as this training is supposed to fail anyway.

This should ensure the usage of mkeys closer to the minimal required size and reduce memory waste. On driver init we create entries for mkeys with clear attributes and powers of 2 sizes from 4 to the max supported size. This solves the issue for anyone using mkeys that fit these requirements. In the use case where an MR is registered with different attributes, like an access flag we can't UMR, we'll create a new cache entry to store it upon dereg. Without this fix, any later registration with same attributes and smaller size will use the newly created cache entry and it's mkeys, disregarding the memory waste of using mkeys larger than required. For example, one worst-case scenario can be when registering and deregistering a 1GB mkey with ATS enabled which will cause the creation of a new cache entry to hold those type of mkeys. A user registering a 4k MR with ATS will end up using the new cache entry and an mkey that can support a 1GB MR, thus wasting x250k memory than actually needed in the HW. Additionally, allow all small registration to use the smallest size cache entry that is initialized on driver load even if size is larger than twice the required size.

The cleanup of the temp cache entries is currently scheduled only when a new entry is created. Since in the cleanup of the entries only the mkeys are destroyed and the cache entry stays in the cache, subsequent registrations might reuse the entry and it will eventually be filled with new mkeys without cleanup ever getting scheduled again. On workloads that register and deregister MRs with a wide range of properties we see the cache ends up holding many cache entries, each holding the max number of mkeys that were ever used through it. Additionally, as the cleanup work is scheduled to run over the whole cache, any mkey that is returned to the cache after the cleanup was scheduled will be held for less than the intended 30 seconds timeout. Solve both issues by dropping the existing remove_ent_work and reusing the existing per-entry work to also handle the temp entries cleanup. Schedule the work to run with a 30 seconds delay every time we push an mkey to a clean temp entry. This ensures the cleanup runs on each entry only 30 seconds after the first mkey was pushed to an empty entry. As we have already been distinguishing between persistent and temp entries when scheduling the cache_work_func, it is not being scheduled in any other flows for the temp entries.

This leads to a situation where BMC (Baseboard Management Controller) cannot retrieve the memory temperature via the i2c interface after i2c DW driver is loaded. Note that BMC can retrieve the memory temperature before booting into OS. [Debugging Detail] 1. dev->pclk and dev->clk are NULL when calling devm_clk_get_optional() in dw_i2c_plat_probe(). 2. The callings of i2c_dw_scl_hcnt() in i2c_dw_set_timings_master() return 65528 (-8 in integer format) or 65533 (-3 in integer format). The following log shows SS's HCNT/LCNT: i2c_designware AMDI0010:01: Standard Mode HCNT:LCNT = 65533:65535 3. The callings of i2c_dw_scl_lcnt() in i2c_dw_set_timings_master() return 65535 (-1 in integer format). The following log shows SS's HCNT/LCNT: i2c_designware AMDI0010:01: Fast Mode HCNT:LCNT = 65533:65535 4. i2c_dw_init_master() configures the register IC_SS_SCL_HCNT with the value 65533. However, the DW i2c databook mentioned the value cannot be higher than 65525. Quote from the DW i2c databook: NOTE: This register must not be programmed to a value higher than 65525, because DW_apb_i2c uses a 16-bit counter to flag an I2C bus idle condition when this counter reaches a value of IC_SS_SCL_HCNT + 10. 5. Since ss_hcnt, ss_lcnt, fs_hcnt, and fs_lcnt are the invalid values, we should not write the corresponding registers.

The exception is (according to HW manuals of the SoCs where this IP is available) the Renesas RZ/A1H. For this, patch introduces the struct riic_of_data::fast_mode_plus. Fast mode plus was tested on RZ/G3S, RZ/G2{L,UL,LC}, RZ/Five by instantiating the RIIC frequency to 1MHz and issuing i2c reads on the fast mode plus capable devices (and the i2c clock frequency was checked on RZ/G3S).

It times out in the driver, but unless transaction is explicitly killed in the controller, it won't be able to perform new transactions anymore. The issue is extremely difficult to reproduce and may take weeks of non- stop smbus traffic. Numerous hours with logic analyzer didn't yield any useful results, it looks like the controller stops toggling SCK line, i.e. the issue is likely in the controller, since device doesn't do clock stretching, so nothing is driving SCK except the host. Explicitly kill transaction on timeout to recover the controller from this state.

This results in calling i2c_new_client_device() from the bus notifier which happens near the device_add() call. If the i2c-core has not yet setup runtime-pm (specifically the no-callbacks and ignore-children flags) for the device embedded inside struct i2c_adapter and the driver for the i2c_client calls pm_runtime_set_active() this will trigger the following error inside __pm_runtime_set_status(): "runtime PM trying to activate child device %s but parent (%s) is not active\n" and the i2c_client's runtime-status will not be updated. Split the device_register() call for the adapter into device_initialize() and device_add() and move the pm-runtime init calls inbetween these 2 calls so that the runtime-status can be correctly set when a driver binds from the bus-notifier. Note the moved pm-runtime init calls just override the initial value of some flags in struct device set by device_initialize() and calling these before device_add() is safe.

This is because subarch.include invokes `uname -m` which on MacOS hosts evaluates to `arm64` but on Linux hosts evaluates to `aarch64`, This allows us to build ARCH=arm64 natively on macOS (as in ARCH need not be specified on an aarch64-based system). Avoid matching arm64 by excluding it from the arm.* sed expression.

Actually, we use the eventfd_ctx as the token so the life cycle of the token should be bound to the VHOST_SET_VRING_CALL instead of vhost_vdpa_setup_vq_irq() which could be called by set_status(). Fixing this by setting up irq bypass producer's token when handling VHOST_SET_VRING_CALL and un-registering the producer before calling vhost_vring_ioctl() to prevent a possible use after free as eventfd could have been released in vhost_vring_ioctl(). And such registering and unregistering will only be done if DRIVER_OK is set.

A guest monitor agent may scan 'oom_kill' from /proc/vmstat, and reports the OOM KILL event. However, the agent may be killed and we will loss this critical event(and the later events). For now we can also grep for magic words in guest kernel log from host side. Rather than this unstable way, virtio balloon reports OOM-KILL invocations instead.

To identify what code is compiled into modules during a kernel build, one can look for the presence of the -DKBUILD_MODFILE and -DKBUILD_MODNAME options in the compile command lines. A simple grep in .*.cmd files for those options is sufficient for this. Unfortunately, these options are only passed when compiling C source files. Various modules also include objects built from assembler source, and these options are not passed in that case. Adding $(modfile_flags) to modkern_aflags (similar to modkern_cflags), and adding $(modname_flags) to a_flags (similar to c_flags) makes it possible to identify which objects are compiled into modules for both C and assembler source files. While KBUILD_MODFILE is sufficient to generate the modules ranges data, KBUILD_MODNAME is passed as well for consistency with the C source code case.

If not, allocate a new one and splice it to the list. The time complexity is O(n^2) in worst cases. Currently the allocation for-loop uses 'unit' as the step size. This actually has taken into account the reuse of last-hop-level MTT bt pages by multiple buffer pages. Thus pages of last hop level will never have been allocated, so there is no need to iterate the hem list in last hop level. Removing this unnecessary iteration can reduce the time complexity to O(n).

PCIe r6.0, sec 6.6, specifies some delays required before software can perform config accesses. Devices that require more time after those delays may respond to config accesses with Configuration Request Retry Status (RRS) completions. Callers of pci_dev_wait() are responsible for delays until the device can respond to config accesses. pci_dev_wait() waits any additional time until the device can successfully complete config accesses. Reading config space of devices that are not present or not ready typically returns ~0 (PCI_ERROR_RESPONSE). Previously we polled the Command register until we got a value other than ~0. This is sometimes a problem because Root Complex handling of RRS completions may include several retries and implementation-specific behavior that is invisible to software (see sec 2.3.2), so the exponential backoff in pci_dev_wait() may not work as intended. Linux enables Configuration RRS Software Visibility on all Root Ports that support it. If it is enabled, read the Vendor ID instead of the Command register. RRS completions cause immediate return of the 0x0001 reserved Vendor ID value, so the pci_dev_wait() backoff works correctly. When a read of Vendor ID eventually completes successfully by returning a non-0x0001 value (the Vendor ID or 0xffff for VFs), the device should be initialized and ready to respond to config requests. For conventional PCI devices or devices below Root Ports that don't support Configuration RRS Software Visibility, poll the Command register as before. This was developed independently, but is very similar to Stanislav Spassov's previous work at https://lore.kernel.org/linux-pci/20200223122057.6504-1-stanspas@amazon.com Link: https://lore.kernel.org/r/20240827234848.4429-2-helgaas@kernel.org Signed-off-by: Bjorn Helgaas Tested-by: Duc Dang --- drivers/pci/pci.c | 41 ++++++++++++++++++++++++++++------------- drivers/pci/pci.h | 5 +++++ drivers/pci/probe.c | 9 +++------ include/linux/pci.h | 1 + 4 files changed, 37 insertions(+), 19 deletions(-) diff --git a/drivers/pci/pci.c b/drivers/pci/pci.c index e3a49f66982d..fc2ecb7fe081 100644 --- a/drivers/pci/pci.c +++ b/drivers/pci/pci.c @@ -1283,7 +1283,9 @@ static int pci_dev_wait(struct pci_dev *dev, char *reset_type, int timeout) { int delay = 1; bool retrain = false; - struct pci_dev *bridge; + struct pci_dev *root, *bridge; + + root = pcie_find_root_port(dev); if (pci_is_pcie(dev)) { bridge = pci_upstream_bridge(dev); @@ -1292,16 +1294,23 @@ static int pci_dev_wait(struct pci_dev *dev, char *reset_type, int timeout) } /* - * After reset, the device should not silently discard config - * requests, but it may still indicate that it needs more time by - * responding to them with CRS completions.

If a new section is allocated during block allocation, it will not be included in the map struct by map_is_mergeable() if the LBA of the allocated block is not contiguous. However, the block already allocated in this process will remain unused due to the LFS mode. This patch avoids the possibility of unused blocks by escaping f2fs_map_blocks() when allocating the last block in a section.

So, it is safe to not set SB_RDONLY flag, let's remove the logic and keep in line w/ ext4 [3].

The major shift in handling the page fault in this scheme is that the HW is taking responsibilty for parsing the faulted mkey instead of the previous approach where the driver would read and parse the wqes and query the mkeys to get to the direct mkey that we need to handle. Therefore, the event we get from FW in this scheme will contain the direct mkey and address we need to handle and require much less work from driver. Additionally, to optimize performance, the FW can generate the event on a memory area that is larger than the faulted memory operation is requiring, to 'prefetch' memory that is around it and will likely be used soon. Unlike previous types of page fault, the memory page scheme fault does not always require a resume command after handling the page fault as the FW can post multiple events on same mkey and will set the 'last' flag only on the page fault that requires the resume command.

Because the superblock is currently 64 bytes, this really verifies mac_size <= 448. This confuses smatch into thinking that mac_size may be as large as 448, which is inconsistent with the later code that assumes the MAC fits in a buffer of size HASH_MAX_DIGESTSIZE (64). In fact mac_size <= HASH_MAX_DIGESTSIZE is guaranteed by the crypto API, as that is the whole point of HASH_MAX_DIGESTSIZE. But, let's be defensive and explicitly check for this. This suppresses the false positive smatch warning. It does not fix an actual bug.

Move the interrupt configuration to the firmware which would allow to accommodate edge triggered interrupts for such SOCs. In order to support the edge interrupts, register irq line in advance and keep track of occurrence during port registering. When the edge interrupts are used, it is observed that some of the interrupts are missed when tcpci_irq() is serving the current interrupt.

To program it driver uses i2c-bus phandle (added in commit '02be19e914b8 dt-bindings: usb: Add support for Microchip usb5744 hub controller') to get i2c client device and then based on usb5744 compatible check calls usb5744 i2c default initialization sequence. Apart from the USB command attach, prevent the hub from suspend. when the USB Attach with SMBus (0xAA56) command is issued to the hub, the hub is getting enumerated and then it puts in a suspend mode. This causes the hub to NAK any SMBus access made by the SMBus Master during this period and not able to see the hub's slave address while running the "i2c probe" command. Prevent the MCU from putting the HUB in suspend mode through register write. The BYPASS_UDC_SUSPEND bit (Bit 3) of the RuntimeFlags2 register at address 0x411D controls this aspect of the hub. The BYPASS_UDC_SUSPEND bit in register 0x411Dh must be set to ensure that the MCU is always enabled and ready to respond to SMBus runtime commands. This register needs to be written before the USB attach command is issued. The byte sequence is as follows: Slave addr: 0x2d 00 00 05 00 01 41 1D 08 Slave addr: 0x2d 99 37 00 Slave addr: 0x2d AA 56 00 Also since usb5744 i2c initialization routine uses i2c SMBus APIs invoke these APIs only when i2c driver is enabled in the kernel configuration.

Cadence controllers may fail to start from the beginning of the dequeue TRB as it doesn't clear the Opaque 'RsvdO' field of the stream context during 'Set TR Dequeue' command. This stream context area is where xHC stores information about the last partially executed TD when a stream is stopped. xHC uses this information to resume the transfer where it left mid TD, when the stream is restarted.

As noted by Doug, the current implementation does not account for start, stop and parity bits when determining the timeout. The helper also does not currently account for the shift register and the two-word intermediate transfer register. A too short timeout can specifically lead to lost characters when waiting for a transfer to complete as the transfer is cancelled on timeout. Instead of determining the poll timeout on every call, store the fifo timeout when updating it in set_termios() and make sure to take the shift and intermediate registers into account. Note that serial core has already added a 20 ms margin to the fifo timeout. Also note that the current uart_fifo_timeout() interface does unnecessary calculations on every call and did not exist in earlier kernels so only store its result once. This facilitates backports too as earlier kernels can derive the timeout from uport->timeout, which has since been removed.

Specifically, the console code only waits for the current tx command to complete when all data has already been written to the fifo. When there are on-going longer transfers this often means that console output is lost when the console code inadvertently "hijacks" the current tx command instead of starting a new one. This can, for example, be observed during boot when console output that should have been interspersed with init output is truncated: [ 9.462317] qcom-snps-eusb2-hsphy fde000.phy: Registered Qcom-eUSB2 phy [ OK ] Found device KBG50ZNS256G KIOXIA Wi[ 9.471743ndows. [ 9.539915] xhci-hcd xhci-hcd.0.auto: xHCI Host Controller Add a new state variable to track how much data has been written to the fifo and use it to determine when the fifo and shift register are both empty. This is needed since there is currently no other known way to determine when the shift register is empty. This in turn allows the console code to interrupt long transfers without losing data. Note that the oops-in-progress case is similarly broken as it does not cancel any active command and also waits for the wrong status flag when attempting to drain the fifo (TX_FIFO_NOT_EMPTY_EN is only set when cancelling a command leaves data in the fifo).

As the polled code cannot take any locks, leave the state variables as they are and instead make sure that the interrupt handler always starts a new tx command when there is data in the write buffer. Since the debugger can interrupt the interrupt handler when it is writing data to the tx fifo, it is currently not possible to fully prevent losing up to 64 bytes of tty output on resume.

It is factored out to a separate function from vchiq_bulk_transfer() to bulk_xfer_waiting_interruptible(). This is a part of vchiq_bulk_transfer refactoring. Each bulk mode will have their dedicated functions to execute bulk transfers. Each mode will be handled separately in subsequent patches. bulk_xfer_waiting_interruptible() is suffixed with "_interruptible" to denote that it can be interrupted when a signal is received. -EAGAIN maybe returned in those cases, similar to what vchiq_bulk_transfer() does. Adjust the vchiq_irq_queue_bulk_tx_rx() in the vchiq-dev.c to call bulk_xfer_waiting_interruptible() for waiting mode. A temporary goto label has been introduced to jump the call execution over vchiq_bulk_transfer() for waiting mode only. When all dedicated bulk transfer calls are introduced, this label shall be dropped. No function changes intended in this patch.

This simplifies the existing vchiq_bulk_transfer() and makes it more readable since all the core logic is handled in vchiq_bulk_xfer_queue_msg_interruptible().

Actual data can be placed in various storage sources (MTD, UBI volume, EEPROM, NVRAM, etc.). Move all generic (NVMEM device independent) code from NVMEM device driver to an NVMEM layout driver. Then add a simple NVMEM layout code on top of it. This allows using NVMEM layout for parsing U-Boot env data stored in any kind of NVMEM device. The old NVMEM glue driver stays in place for handling bindings in the MTD context. To avoid code duplication it uses exported layout parsing function. Please note that handling MTD & NVMEM layout bindings may be refactored in the future.

Communication with the bootloader can be moved out of gb-beagleplay driver if required, but I am keeping it here since there are no immediate plans to use the on-board cc1352p7 for anything other than greybus (BeagleConnect Technology). Additionally, there do not seem to any other devices using cc1352p7 or it's cousins as a co-processor. Boot and Reset GPIOs are used to enable cc1352p7 bootloader backdoor for flashing. The delays while starting bootloader are taken from the userspace flasher since the technical specification does not provide sufficient information regarding it. Flashing is skipped in case we are trying to flash the same image as the one that is currently present. This is determined by CRC32 calculation of the supplied firmware and Flash data. We also do a CRC32 check after flashing to ensure that the firmware was flashed properly. Firmware size should be 704 KB.

This macro determines if the address needs to be fixed by checking if it is within the range starting from ROM address up to the size of (2 * XIP_OFFSET). This means if the kernel size is bigger than (2 * XIP_OFFSET), some addresses would not be fixed up. XIP kernel can still work if the above scenario does not happen. But this macro is obviously incorrect. Rewrite this macro to only fix up addresses within the data section.

For XIP kernel, there are 2 different offsets because the read-only part of the kernel resides in ROM while the rest is in RAM. The offset to ROM is in kernel_map.va_kernel_xip_pa_offset, while the offset to RAM is not stored anywhere: it is calculated on-the-fly. Remove this confusing "va_kernel_pa_offset" and add "va_kernel_xip_data_pa_offset" as its replacement. This new variable is the offset of virtual mapping of the kernel's data portion to the corresponding physical addresses. With the introduction of this new variable, also rename va_kernel_xip_pa_offset -> va_kernel_xip_text_pa_offset to make it clear that this one is about the .text section.

Also we had to split single ep93xx platform_device into multiple, one for each port, without this we can't do a full working transition from legacy platform code into device tree capable. All GPIO_LOOKUP were change to match new chip namings.

The -Zfixed-x18 flag is required to use SCS on arm64, and requires rustc version 1.80.0 or greater. This restriction is reflected in Kconfig. When CONFIG_DYNAMIC_SCS is enabled, the build will be configured to include unwind tables in the build artifacts. Dynamic SCS uses the unwind tables at boot to find all places that need to be patched. The -Cforce-unwind-tables=y flag ensures that unwind tables are available for Rust code. In non-dynamic mode, the -Zsanitizer=shadow-call-stack flag is what enables the SCS sanitizer. Using this flag requires rustc version 1.82.0 or greater on the targets used by Rust in the kernel. This restriction is reflected in Kconfig. It is possible to avoid the requirement of rustc 1.80.0 by using -Ctarget-feature=+reserve-x18 instead of -Zfixed-x18. However, this flag emits a warning during the build, so this patch does not add support for using it and instead requires 1.80.0 or greater. The dependency is placed on `select HAVE_RUST` to avoid a situation where enabling Rust silently turns off the sanitizer. Instead, turning on the sanitizer results in Rust being disabled. We generally do not want changes to CONFIG_RUST to result in any mitigations being changed or turned off. At the time of writing, rustc 1.82.0 only exists via the nightly release channel. There is a chance that the -Zsanitizer=shadow-call-stack flag will end up needing 1.83.0 instead, but I think it is small.

This ensures that integer types of the same size and signedness are considered compatible by the Control Flow Integrity sanitizer. The security impact of this flag is minimal. When Sami Tolvanen looked into it, he found that integer normalization reduced the number of unique type hashes in the kernel by ~1%, which is acceptable. This option exists for compatibility with Rust, as C and Rust do not have the same set of integer types. There are cases where C has two different integer types of the same size and signedness, but Rust only has one integer type of that size and signedness. When Rust calls into C functions using such types in their signature, this results in CFI failures. One example is 'unsigned long long' and 'unsigned long' which are both 64-bit on LP64 targets, so on those targets this flag will give both types the same CFI tag. This flag changes the ABI heavily. It is not applied automatically when CONFIG_RUST is turned on to make sure that the CONFIG_RUST option does not change the ABI of C code. For example, some build may need to make other changes atomically with toggling this flag. Having it be a separate option makes it possible to first turn on normalized integer tags, and then later turn on CONFIG_RUST. Similarly, when turning on CONFIG_RUST in a build, you may need a few attempts where the RUST=y commit gets reverted a few times. It is inconvenient if reverting RUST=y also requires reverting the changes you made to support normalized integer tags. To avoid having this flag impact builds that don't care about this, the next patch in this series will make CONFIG_RUST turn on this option using `select` rather than `depends on`.

Previously, mlx5_ib stored and managed the associated net devices internally. Replace internal net device management in mlx5_ib with ib_device_set_netdev() when attaching/detaching a net device and ib_device_get_netdev() when retrieving the net device. Export ib_device_get_netdev(). For mlx5 representors/PFs/VFs and lag creation we replace the netdev assignments with the IB set/get netdev functions. In active-backup mode lag the active slave net device is stored in the lag itself. To assure the net device stored in a lag bond IB device is the active slave we implement the following: - mlx5_core: when modifying the slave of a bond we send the internal driver event MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE. - mlx5_ib: when catching the event call ib_device_set_netdev() This patch also ensures the correct IB events are sent in switchdev lag. While at it, when in multiport eswitch mode, only a single IB device is created for all ports. The said IB device will receive all netdev events of its VFs once loaded, thus to avoid overwriting the mapping of PF IB device to PF netdev, ignore NETDEV_REGISTER events if the ib device has already been mapped to a netdev.

Currently driver doesn't re-initialize the device. Add support for re-initialize the RoCE device. RoCE device is removed and re-attached in the ulp_stop and ulp_start respectively. The recovery logic expects the RoCE driver to be registered with L2 driver while its being removed. So the driver avoids unregistering with L2 driver in the recovery path.

With CONFIG_PREEMPT_RT enabled, __mutex_init() is a macro. I assume this is why mutex_init() is defined twice as exactly the same macro. Prepare for introducing a new macro for mutex initialization by combining the two identical mutex_init() definitions into a single definition. This patch does not change any functionality because the C preprocessor expands macros when it encounters the macro name and not when a macro definition is encountered.

There is only one caller and because of the way that the types work out, returning negative error codes is not a problem. They will be treated as greater than USB_SPEED_HIGH and ignored as invalid.

However, some UCSI implementations do not follow this rule and report bogus data in CCI along with the busy indicator. Ignore the contents of CCI if the busy indicator is set. If a command timeout is hit it is possible that the EVENT_PENDING bit is cleared while connector work is still scheduled which can cause the EVENT_PENDING bit to go out of sync with scheduled connector work. Check and set the EVENT_PENDING bit on entry to ucsi_handle_connector_change() to fix this. Finally, check UCSI_CCI_BUSY before the return code of ->sync_control.

The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always treated as reserved by the E820 conversion logic.

On one of the new unreleased Qcom SoC, PHY enablement depends on the active refclk. And on all of the supported Qcom endpoint SoCs, refclk comes from the host (RC). So calling qcom_pcie_enable_resources() without refclk causes the NoC (Network On Chip) error in the endpoint SoC and in turn results in a whole SoC crash and rebooting into EDL (Emergency Download) mode which is an unrecoverable state. But qcom_pcie_enable_resources() is already called by qcom_pcie_perst_deassert() when PERST# is deasserted, and refclk is available at that time. Hence, remove the unnecessary call to qcom_pcie_enable_resources() from qcom_pcie_ep_probe() to prevent the above mentioned crash. It should be noted that this commit prevents the crash only under normal working condition (booting endpoint before host), but the crash may also occur if PERST# assert happens at the wrong time. For avoiding the crash completely, it is recommended to use SRIS mode which allows the endpoint SoC to generate its own refclk. The driver is not supporting SRIS mode currently, but will be added in the future.

charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, the dw_pcie::max_link_speed has a valid value only if the controller driver restricts the maximum link speed in the driver or if the platform does so in the devicetree using the 'max-link-speed' property. But having the maximum supported link speed of the platform would be helpful for the vendor drivers to configure any link specific settings. So in the case of non-valid value in dw_pcie::max_link_speed, just cache the hardware default value from Link Capability register. While at it, remove the 'max_link_speed' argument to the dw_pcie_link_set_max_speed() function since the value can be retrieved within the function.

This can impact receiver's ability to capture signals accurately. Hence, as signal compensation is achieved through appropriate lane equalization, apply lane equalization settings at both transmitter and receiver which results in an increase in the PCIe signal strength. While at it, modify the pcie-tegra194 driver to make use of the common GEN3_EQ_CONTROL_OFF definitions in pcie-designware.h.

R. Silva" Date: Wed, 7 Aug 2024 09:19:07 -0600 Subject: [PATCH 2173/2648] rpmsg: glink: Avoid -Wflex-array-member-not-at-end warnings -Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `__struct_group()` helper to create a new tagged `struct glink_msg_hdr`. This structure groups together all the members of the flexible `struct glink_msg` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct members currently causing trouble from `struct glink_msg` to `struct glink_msg_hdr`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct glink_msg_hdr` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. We also use `container_of()` whenever we need to retrieve a pointer to the flexible structure, through which we can access the flexible-array member, if necessary. Additionally, we use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of a flexible structure where the size for the flexible-array member is known at compile-time. So, with these changes, fix the following warnings: drivers/rpmsg/qcom_glink_native.c:51:26: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/rpmsg/qcom_glink_native.c:459:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/rpmsg/qcom_glink_native.c:846:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/rpmsg/qcom_glink_native.c:968:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/rpmsg/qcom_glink_native.c:1380:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

Most of the callers of pci_bus_find_domain_nr(), store the domain number in pci_bus::domain_nr. As such, the pci_bus_release_domain_nr() implicitly frees the domain number by dereferencing 'struct pci_bus'. However, one of the callers of this API, the PCI endpoint subsystem, doesn't have 'struct pci_bus', so it only passes NULL. Due to this, the API will end up dereferencing the NULL pointer. To fix this issue, pass the domain number to this API explicitly. Since 'struct pci_bus' is not used for anything else other than extracting the domain number, it makes sense to pass the domain number directly.

Then in order to make sure that new page table entries were seen by the page table walker, we had to preventively emit a sfence.vma on all harts [3] but this solution is very costly since it relies on IPI. And even there, we could end up in a loop of vmalloc faults if a vmalloc allocation is done in the IPI path (for example if it is traced, see [4]), which could result in a kernel stack overflow. Those preventive sfence.vma needed to be emitted because: - if the uarch caches invalid entries, the new mapping may not be observed by the page table walker and an invalidation may be needed. - if the uarch does not cache invalid entries, a reordered access could "miss" the new mapping and traps: in that case, we would actually only need to retry the access, no sfence.vma is required. So this patch removes those preventive sfence.vma and actually handles the possible (and unlikely) exceptions. And since the kernel stacks mappings lie in the vmalloc area, this handling must be done very early when the trap is taken, at the very beginning of handle_exception: this also rules out the vmalloc allocations in the fault path.

The following sequence of commands causes a livelock - there will be workqueue process looping and consuming 100% CPU: dmsetup create --notable test truncate -s 1MiB testdata losetup /dev/loop0 testdata dmsetup load test --table '0 2048 linear /dev/loop0 0' dd if=/dev/zero of=/dev/dm-0 bs=16k count=1 conv=fdatasync The livelock is caused by the commit fa247089de99. The commit claims that it fixes a race condition, however, it is unknown what the actual race condition is and what program is involved in the race condition. When the inactive table is loaded, the nodes /dev/dm-0 and /sys/block/dm-0 are created. /dev/dm-0 has zero size at this point. When the device is suspended and resumed, the nodes /dev/mapper/test and /dev/disk/* are created. If some program opens a block device before it is created by dmsetup or lvm, the program is buggy, so dm could just report an error as it used to do before.

However, init_cpu_topology() is only called from smpboot.c:smp_prepare_cpus() and thus only available when CONFIG_SMP is defined. To support non-SMP enabled kernels to still detect cache hierarchy, we add back the init_cache_level() function. The init_level_allocate_ci() function handles this gracefully on SMP-enabled kernels anyway where fetch_cache_info() is called from init_cpu_topology() earlier in the boot phase.

Enabling CFI with Rust requires that CFI is configured to normalize integer types so that all integer types of the same size and signedness are compatible under CFI. Rust and C use the same LLVM backend for code generation, so Rust KCFI is compatible with the KCFI used in the kernel for C. In the case of FineIBT, CFI also depends on -Zpatchable-function-entry for rewriting the function prologue, so we set that flag for Rust as well. The flag for FineIBT requires rustc 1.80.0 or later, so include a Kconfig requirement for that. Enabling Rust will select CFI_ICALL_NORMALIZE_INTEGERS because the flag is required to use Rust with CFI. Using select rather than `depends on` avoids the case where Rust is not visible in menuconfig due to CFI_ICALL_NORMALIZE_INTEGERS not being enabled. One disadvantage of select is that RUST must `depends on` all of the things that CFI_ICALL_NORMALIZE_INTEGERS depends on to avoid invalid configurations. Alice has been using KCFI on her phone for several months, so it is reasonably well tested on arm64.

The various_address_sockets tests ensure that UNIX sockets bound to a filesystem pathname and unnamed sockets created by socketpair can still connect to a socket outside of their scoped domain, meaning that even if the domain is scoped with LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET, the socket can connect to a socket outside the scoped domain.

The ability to send a signal for a sandboxed process should be scoped the same way abstract UNIX sockets are scoped. Therefore, we extend the "scoped" field in a ruleset with LANDLOCK_SCOPE_SIGNAL to specify that a ruleset will deny sending any signal from within a sandbox process to its parent (i.e. any parent sandbox or non-sandboxed processes). This patch adds file_set_fowner and file_free_security hooks to set and release a pointer to the file owner's domain. This pointer, fown_domain in landlock_file_security will be used in file_send_sigiotask to check if the process can send a signal. The ruleset_with_unknown_scope test is updated to support LANDLOCK_SCOPE_SIGNAL. This depends on two new changes: - commit 1934b212615d ("file: reclaim 24 bytes from f_owner"): replace container_of(fown, struct file, f_owner) with fown->file . - commit 26f204380a3c ("fs: Fix file_set_fowner LSM hook inconsistencies"): lock before calling the hook.

It is quite possible that a ring configured for inbound traffic with multishot be several hours without receiving new request submissions 2. NAPI busy poll does not perform any credential validation 3. If the thread is awaken by task work, processing the task work is prioritary over NAPI busy loop. This is why a second loop has been created after the io_sq_tw() call instead of doing the busy loop in __io_sq_thread() outside its credential acquisition block.

A custom one allows to debug CPUs that are stuck with interrupts disabled with NMI support in the future. And using an IPI is better than the generic one since it avoids the potential situation described in the generic kgdb_call_nmi_hook(). As Andrew pointed out, once there is NMI support, we can easily extend this and the CPU backtrace support to use NMIs.

At the beginning, the thought is tended to decode the secondary stack instruction "sub.d $sp, $sp, $t0" and set it as a label, then check this label for the two frame pointer instructions to change the cfa base and cfa offset during the period of secondary stack in update_cfi_state(). This is valid for GCC but invalid for Clang due to there are different secondary stack instructions for ClangBuiltLinux on LoongArch, something like this: 0000000000000000 : ... 88: 00119064 sub.d $a0, $sp, $a0 8c: 00150083 or $sp, $a0, $zero ... Actually, it equals to a single instruction "sub.d $sp, $sp, $a0", but there is no proper condition to check it as a label like GCC, and so the beginning thought is not a good way. Essentially, there are two special frame pointer instructions which are "addi.d $fp, $sp, imm" and "addi.d $sp, $fp, imm", the first one points fp to the original stack top and the second one restores the original stack bottom from fp. Based on the above analysis, in order to avoid adding an arch-specific update_cfi_state(), we just add a member "frame_pointer" in the "struct symbol" as a label to avoid affecting the current normal case, then set it as true only if there is "addi.d $sp, $fp, imm". The last is to check this label for the two frame pointer instructions to change the cfa base and cfa offset in update_cfi_state(). Tested with the following two configs: (1) CONFIG_RANDOMIZE_KSTACK_OFFSET=y && CONFIG_RANDOMIZE_KSTACK_OFFSET_DEFAULT=n (2) CONFIG_RANDOMIZE_KSTACK_OFFSET=y && CONFIG_RANDOMIZE_KSTACK_OFFSET_DEFAULT=y By the way, there is no effect for x86 with this patch, tested on the x86 machine with Fedora 40 system.

However, the "none" scheduler does not have a module and as a result, elv_iosched_load_module() always returns an error when trying to switch to this valid scheduler. Fix this by ignoring the return value of the request_module() call done by elv_iosched_load_module(). This restores the behavior before commit 734e1a860312, which was to ignore the request_module() result and instead rely on elevator_change() to handle the "none" scheduler case.

The race happens like this: 1) A program opens a file descriptor for a file and then spawns two threads (with the pthreads library for example), lets call them task A and task B; 2) Task A calls lseek with SEEK_DATA or SEEK_HOLE and ends up at file.c:find_desired_extent() while holding a read lock on the inode; 3) At the start of find_desired_extent(), it extracts the file's private_data pointer into a local variable named 'private', which has a value of NULL; 4) Task B also calls lseek with SEEK_DATA or SEEK_HOLE, locks the inode in shared mode and enters file.c:find_desired_extent(), where it also extracts file->private_data into its local variable 'private', which has a NULL value; 5) Because it saw a NULL file private, task A allocates a private structure and assigns to the file structure; 6) Task B also saw a NULL file private so it also allocates its own file private and then assigns it to the same file structure, since both tasks are using the same file descriptor. At this point we leak the private structure allocated by task A. Besides the memory leak, there's also the detail that both tasks end up using the same cached state record in the private structure (struct btrfs_file_private::llseek_cached_state), which can result in a use-after-free problem since one task can free it while the other is still using it (only one task took a reference count on it). Also, sharing the cached state is not a good idea since it could result in incorrect results in the future - right now it should not be a problem because it end ups being used only in extent-io-tree.c:count_range_bits() where we do range validation before using the cached state. Fix this by protecting the private assignment and check of a file while holding the inode's spinlock and keep track of the task that allocated the private, so that it's used only by that task in order to prevent user-after-free issues with the cached state record as well as potentially using it incorrectly in the future.

But in above case, the value is completely sane, not really showing the problem. [CAUSE] The root cause of the problem is the deprecated feature, inode cache. This feature results a special inode number, -12ULL, and it's no longer recognized by tree-checker, triggering the error. The direct problem here is the output of data ref objectid. The value shown is in fact the dref_root (subvolume id), not the dref_objectid (inode number). [FIX] Fix the output to use dref_objectid instead.

To easily reproduce this issue, you can follow the steps below: 1. format a device to exFAT and then mount (with a full disk erase) 2. dd if=/dev/zero of=/exfat_mount/test.img bs=1M count=8192 3. eject the device You may find that the dd process does not stop immediately and may continue for a long time. The root cause of this issue is that during buffer write process, exFAT does not need to access the disk to look up directory entries or the FAT table (whereas FAT would do) every time data is written. Instead, exFAT simply marks the buffer as dirty and returns, delegating the writeback operation to the writeback process. If the disk cannot be accessed at this time, the error will only be returned to the writeback process, and the original process will not receive the error, so it cannot be returned to the user side. When the disk cannot be accessed normally, an error should be returned to stop the writing process. Implement sops->shutdown and ioctl to shut down the file system when underlying block device is marked dead.

Consider a scenario where, while device->ldev->md.uuid[UI_BITMAP] passes the validity check when its value is not zero, the value of device->ldev->md.uuid[UI_BITMAP] is written to zero. In this case, the check in drbd_uuid_set_bm might refer to the old value of device->ldev->md.uuid[UI_BITMAP] (before locking), which allows an invalid value to pass the validity check, resulting in inconsistency. To address this issue, it is recommended to include the data validity check within the locked section of the function. This modification ensures that the value of device->ldev->md.uuid[UI_BITMAP] does not change during the validation process, thereby maintaining its integrity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

And if the process has called personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for RW pages, this will actually result in remapping the pages to RWX, bypassing a W^X policy enforced by SELinux. So we should check prot by security_mmap_file LSM hook in the remap_file_pages syscall handler before do_mmap() is called. Otherwise, it potentially permits an attacker to bypass a W^X policy enforced by SELinux. The bypass is similar to CVE-2016-10044, which bypass the same thing via AIO and can be found in [1].

Thus, the entire logic after the introduction of aqr_wait_reset_complete() is now completely side-stepped, because if aqr_wait_reset_complete() succeeds, MDIO_MMD_VEND1:VEND1_GLOBAL_FW_ID could have only been a non-zero value. The handling of the case where the register reads as 0 is dead code, due to the previous -ETIMEDOUT having stopped execution and returning a fatal error to the caller. We never attempt to load new firmware if no firmware is present. Based on static code analysis, I guess we should simply introduce a switch/case statement based on the return code from aqr_wait_reset_complete(), to determine whether to load firmware or not. I am not intending to change the procedure through which the driver determines whether to load firmware or not, as I am unaware of alternative possibilities. At the same time, Russell King suggests that if aqr_wait_reset_complete() is expected to return -ETIMEDOUT as part of normal operation and not just catastrophic failure, the use of phy_read_mmd_poll_timeout() is improper, since that has an embedded print inside. Just open-code a call to read_poll_timeout() to avoid printing -ETIMEDOUT, but continue printing actual read errors from the MDIO bus.

Budget does not affect the number of Tx completions we can process for NAPI, so we use the ring size as the limit instead of budget.

seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition In the ether3_probe function, a timer is initialized with a callback function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove.

Those two directly translate to TIF_NOTIFY_SIGNAL or TIF_NOTIFY_RESUME, and can be used for a variety of use case outside of task_work. However, io_cqring_wait_schedule() only tests explicitly for TIF_NOTIFY_SIGNAL. This means it can miss if task_work got added for the task, but used a different kind of signaling mechanism (or none at all). Normally this doesn't matter as any task_work will be run once the task exits to userspace, except if: 1) The ring is setup with DEFER_TASKRUN 2) The local work item may generate normal task_work For condition 2, this can happen when closing a file and it's the final put of that file, for example. This can cause stalls where a task is waiting to make progress inside io_cqring_wait(), but there's nothing else that will wake it up. Hence change the "should we schedule or loop around" check to check for the presence of task_work explicitly, rather than just TIF_NOTIFY_SIGNAL as the mechanism. While in there, also change the ordering of what type of task_work first in terms of ordering, to both make it consistent with other task_work runs in io_uring, but also to better handle the case of defer task_work generating normal task_work, like in the above example.

This will be useful for tracing tools to find what functions are for various built-in modules. The offset range data for builtin modules is generated using: - modules.builtin: associates object files with module names - vmlinux.map: provides load order of sections and offset of first member per section - vmlinux.o.map: provides offset of object file content per section - .*.cmd: build cmd file with KBUILD_MODFILE The generated data will look like: .text 00000000-00000000 = _text .text 0000baf0-0000cb10 amd_uncore .text 0009bd10-0009c8e0 iosf_mbi ... .text 00b9f080-00ba011a intel_skl_int3472_discrete .text 00ba0120-00ba03c0 intel_skl_int3472_discrete intel_skl_int3472_tps68470 .text 00ba03c0-00ba08d6 intel_skl_int3472_tps68470 ... .data 00000000-00000000 = _sdata .data 0000f020-0000f680 amd_uncore For each ELF section, it lists the offset of the first symbol. This can be used to determine the base address of the section at runtime. Next, it lists (in strict ascending order) offset ranges in that section that cover the symbols of one or more builtin modules. Multiple ranges can apply to a single module, and ranges can be shared between modules. The CONFIG_BUILTIN_MODULE_RANGES option controls whether offset range data is generated for kernel modules that are built into the kernel image. How it works: 1. The modules.builtin file is parsed to obtain a list of built-in module names and their associated object names (the .ko file that the module would be in if it were a loadable module, hereafter referred to as ). This object name can be used to identify objects in the kernel compile because any C or assembler code that ends up into a built-in module will have the option -DKBUILD_MODFILE= present in its build command, and those can be found in the ..cmd file in the kernel build tree. If an object is part of multiple modules, they will all be listed in the KBUILD_MODFILE option argument. This allows us to conclusively determine whether an object in the kernel build belong to any modules, and which. 2. The vmlinux.map is parsed next to determine the base address of each top level section so that all addresses into the section can be turned into offsets. This makes it possible to handle sections getting loaded at different addresses at system boot. We also determine an 'anchor' symbol at the beginning of each section to make it possible to calculate the true base address of a section at runtime (i.e. symbol address - symbol offset). We collect start addresses of sections that are included in the top level section. This is used when vmlinux is linked using vmlinux.o, because in that case, we need to look at the vmlinux.o linker map to know what object a symbol is found in. And finally, we process each symbol that is listed in vmlinux.map (or vmlinux.o.map) based on the following structure: vmlinux linked from vmlinux.a: vmlinux.map: -- might be same as top level section) -- built-in association known -- belongs to module(s) object belongs to ... vmlinux linked from vmlinux.o: vmlinux.map: -- might be same as top level section) vmlinux.o -- need to use vmlinux.o.map -- ignored ... vmlinux.o.map:
-- built-in association known -- belongs to module(s) object belongs to ... 3. As sections, objects, and symbols are processed, offset ranges are constructed in a straight-forward way: - If the symbol belongs to one or more built-in modules: - If we were working on the same module(s), extend the range to include this object - If we were working on another module(s), close that range, and start the new one - If the symbol does not belong to any built-in modules: - If we were working on a module(s) range, close that range Signed-off-by: Kris Van Hees Reviewed-by: Nick Alcock Reviewed-by: Alan Maguire Reviewed-by: Steven Rostedt (Google) Tested-by: Sam James Reviewed-by: Sami Tolvanen Tested-by: Sami Tolvanen Signed-off-by: Masahiro Yamada --- .gitignore | 1 + Documentation/dontdiff | 1 + Documentation/kbuild/kbuild.rst | 5 + Documentation/process/changes.rst | 7 + Makefile | 1 + lib/Kconfig.debug | 15 + scripts/Makefile.vmlinux | 18 + scripts/Makefile.vmlinux_o | 3 + scripts/generate_builtin_ranges.awk | 508 ++++++++++++++++++++++++++++ 9 files changed, 559 insertions(+) create mode 100755 scripts/generate_builtin_ranges.awk diff --git a/.gitignore b/.gitignore index c06a3ef6d6c6..625bf59ad845 100644 --- a/.gitignore +++ b/.gitignore @@ -69,6 +69,7 @@ modules.order /Module.markers /modules.builtin /modules.builtin.modinfo +/modules.builtin.ranges /modules.nsdeps # diff --git a/Documentation/dontdiff b/Documentation/dontdiff index 3c399f132e2d..a867aea95c40 100644 --- a/Documentation/dontdiff +++ b/Documentation/dontdiff @@ -180,6 +180,7 @@ modpost modules-only.symvers modules.builtin modules.builtin.modinfo +modules.builtin.ranges modules.nsdeps modules.order modversions.h* diff --git a/Documentation/kbuild/kbuild.rst b/Documentation/kbuild/kbuild.rst index 9c8d1d046ea5..a0f7726c46f8 100644 --- a/Documentation/kbuild/kbuild.rst +++ b/Documentation/kbuild/kbuild.rst @@ -22,6 +22,11 @@ modules.builtin.modinfo This file contains modinfo from all modules that are built into the kernel.

This data can be used to determine whether a symbol at a particular address belongs to module code that was configured to be compiled into the kernel proper as a built-in module (rather than as a standalone module). This patch adds a script that uses the generated modules.builtin.ranges data to annotate the symbols in the System.map with module names if their address falls within a range that belongs to one or more built-in modules. It then processes the vmlinux.map (and if needed, vmlinux.o.map) to verify the annotation: - For each top-level section: - For each object in the section: - Determine whether the object is part of a built-in module (using modules.builtin and the .*.cmd file used to compile the object as suggested in [0]) - For each symbol in that object, verify that the built-in module association (or lack thereof) matches the annotation given to the symbol.

Consider the following code: config FOO bool "FOO" depends on (A || B) && C config BAR bool "BAR" depends on (A || B) && C config BAZ bool "BAZ" depends on A || B The "depends on" lines are similar, but currently a separate AST is allocated for each one. The current data structure looks like this: FOO->dep ==> AND BAR->dep ==> AND BAZ->dep ==> OR / \ / \ / \ OR C OR C A B / \ / \ A B A B This is redundant; FOO->dep and BAR->dep have identical ASTs but different memory instances. We can optimize this; FOO->dep and BAR->dep can share the same AST, and BAZ->dep can reference its sub tree. The optimized data structure looks like this: FOO->dep, BAR->dep ==> AND / \ BAZ->dep ==> OR C / \ A B This commit introduces a hash table to keep track of allocated expressions. If an identical expression is found, it is reused. This does not necessarily result in memory savings, as menu_finalize() transforms expressions without freeing up stale ones. This will be addressed later. One optimization that can be easily implemented is caching the expression's value. Once FOO's dependency, (A || B) && C, is calculated, it can be cached, eliminating the need to recalculate it for BAR. This commit also reverts commit e983b7b17ad1 ("kconfig/menu.c: fix multiple references to expressions in menu_add_prop()").

Check for needing to reschedule while flushing, and drop our locks and do so if necessary. There's no state to maintain here as overflows always prune from head-of-list, hence it's fine to drop and reacquire the locks at the end of the loop.

Setting SCBR in atmel_qspi_setup() erases a possible DLYBS setting from atmel_qspi_set_cs_timing(). The DLYBS setting is applied by ORing over the current setting, without resetting the bits first.

However, the problem is not completely solved. If `CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX` on 64-bit architecture, for example, when system memory is equal to CRASH_ADDR_LOW_MAX on RISCV64, the following infinite loop will also occur: -> reserve_crashkernel_generic() and high is true -> alloc at [CRASH_ADDR_LOW_MAX, CRASH_ADDR_HIGH_MAX] fail -> alloc at [0, CRASH_ADDR_LOW_MAX] fail and repeatedly (because CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX). As Catalin suggested, do not remove the ",high" reservation fallback to ",low" logic which will change arm64's kdump behavior, but fix it by skipping the above situation similar to commit d2f32f23190b ("crash: fix x86_32 crash memory reserve dead loop").

The NTB rx buffer ring is a single chunk DMA buffer that is allocated against the NTB PCI device. If the receive side is using a DMA device, then the buffers are remapped against the DMA device before being submitted via the dmaengine API. This scheme becomes a problem when the physical memory is discontiguous. When dma_map_page() is called on the kernel virtual address from the dma_alloc_coherent() call, the new IOVA mapping no longer points to all the physical memory allocated due to being discontiguous. Change dma_alloc_coherent() to dma_alloc_attrs() in order to force DMA_ATTR_FORCE_CONTIGUOUS attribute. This is the best fix for the circumstance. A potential future solution may be having the DMA mapping API providing a way to alias an existing IOVA mapping to a new device perhaps. This fix is not to fix the patch pointed to by the fixes tag, but to fix the issue arised in the ntb_transport driver on x86 platforms after the said patch is applied.

Before the thread can exit it must call svc_exit_thread(), but that requires the service mutex to be held. The thread cannot simply take the mutex as that could deadlock if there is a concurrent attempt to shut down all threads (which is unlikely, but not impossible). nfsd currently call svc_exit_thread() unprotected in the unlikely event that unshare_fs_struct() fails. We can clean this up by introducing svc_thread_init_status() by which an svc thread can report whether initialisation has succeeded. If it has, it continues normally into the action loop. If it has not, svc_thread_init_status() immediately aborts the thread. svc_start_kthread() waits for either of these to happen, and calls svc_exit_thread() (under the mutex) if the thread aborted.

Also as i_am_nfsd() is only used in combination with kthread_data(), replace it with nfsd_current_rqst() which combines the two and returns a valid svc_rqst, or NULL.

There is code scattered around nfsd which chooses an error status based on the particular version of nfs being used. It is cleaner to have the version specific choices in version specific code. With this patch common code returns the most specific error code possible and the version specific code maps that if necessary. Both v2 (nfsproc.c) and v3 (nfs3proc.c) now have a "map_status()" function which is called to map the resp->status before each non-trivial nfsd_proc_* or nfsd3_proc_* function returns. NFS4ERR_SYMLINK and NFS4ERR_WRONG_TYPE introduce extra complications and are left for a later patch.

Rather than using ad hoc values for internal errors (30000, 11000, ...) use 'enum' to sequentially allocate numbers starting from the first known available number - now visible as NFS4ERR_FIRST_FREE. The goal is values that are distinct from all be32 error codes. To get those we must first select integers that are not already used, then convert them with cpu_to_be32().

If an NFS operation expects a particular sort of object (file, dir, link, etc) but gets a file handle for a different sort of object, it must return an error. The actual error varies among NFS versions in non-trivial ways. For v2 and v3 there are ISDIR and NOTDIR errors and, for NFSv4 only, INVAL is suitable. For v4.0 there is also NFS4ERR_SYMLINK which should be used if a SYMLINK was found when not expected. This take precedence over NOTDIR. For v4.1+ there is also NFS4ERR_WRONG_TYPE which should be used in preference to EINVAL when none of the specific error codes apply. When nfsd_mode_check() finds a symlink where it expected a directory it needs to return an error code that can be converted to NOTDIR for v2 or v3 but will be SYMLINK for v4. It must be different from the error code returns when it finds a symlink but expects a regular file - that must be converted to EINVAL or SYMLINK. So we introduce an internal error code nfserr_symlink_not_dir which each version converts as appropriate. nfsd_check_obj_isreg() is similar to nfsd_mode_check() except that it is only used by NFSv4 and only for OPEN. NFSERR_INVAL is never a suitable error if the object is the wrong time. For v4.0 we use nfserr_symlink for non-dirs even if not a symlink. For v4.1 we have nfserr_wrong_type. We handle this difference in-place in nfsd_check_obj_isreg() as there is nothing to be gained by delaying the choice to nfsd4_map_status(). As a result of these changes, nfsd_mode_check() doesn't need an rqstp arg any more. Note that NFSv4 operations are actually performed in the xdr code(!!!) so to the only place that we can map the status code successfully is in nfsd4_encode_operation().

However, if the CB_OFFLOAD never arrives at the client (for example, if a network partition occurs just as the server sends the CB_OFFLOAD operation), the client will never receive this verifier. Thus, if the client sends a follow-up COMMIT, there is no way for the client to assess the COMMIT result. The usual recovery for a missing CB_OFFLOAD is for the client to send an OFFLOAD_STATUS operation, but that operation does not carry a write verifier in its result. Neither does it carry a stable_how4 value, so the client /must/ send a COMMIT in this case -- which will always fail because currently there's still no write verifier in the COPY result. Thus the server needs to return a normal write verifier in its COPY result even if the COPY operation is to be performed asynchronously. If the server recognizes the callback stateid in subsequent OFFLOAD_STATUS operations, then obviously it has not restarted, and the write verifier the client received in the COPY result is still valid and can be used to assess a COMMIT of the copied data, if one is needed.

In addition, AFAICT each async COPY can copy an unlimited number of 4MB chunks, so can run for a long time. Thus IMO async COPY can become a DoS vector. Add a restriction mechanism that bounds the number of concurrent background COPY operations. Start simple and try to be fair -- this patch implements a per-namespace limit. An async COPY request that occurs while this limit is exceeded gets NFS4ERR_DELAY. The requesting client can choose to send the request again after a delay or fall back to a traditional read/write style copy.

A new filehandle would be recorded in the "new" bit set. That would then be switch to the "old" bit set between 0 and 30 seconds later, and it would remain as the "old" bit set for 30 seconds. Unfortunately the code intended to clear the old bit set once it reached 30 seconds old, preparing it to be the next new bit set, instead cleared the *new* bit set before switching it to be the old bit set. This means that the "old" bit set is always empty and delegations are blocked between 0 and 30 seconds. This patch updates bd->new before clearing the set with that index, instead of afterwards.

The generator attempts to match the usual C coding style of the Linux kernel's SunRPC consumers. This approach is similar to the netlink code generator in tools/net/ynl . The maintainability benefits of machine-generated XDR code include: - Stronger type checking - Reduces the number of bugs introduced by human error - Makes the XDR code easier to audit and analyze - Enables rapid prototyping of new RPC-based protocols - Hardens the layering between protocol logic and marshaling - Makes it easier to add observability on demand - Unit tests might be built for both the tool and (automatically) for the generated code In addition, converting the XDR layer to use memory-safe languages such as Rust will be easier if much of the code can be converted automatically.

are typically specified using a language defined by +RFC 4506. In fact, all IETF-published NFS specifications provide a +description of the specified protocol using this language. + +Since the 1990's, user space consumers of SunRPC have had access to +a tool that could read such XDR specifications and then generate C +code that implements the RPC portions of that protocol. This tool is +called rpcgen. + +This RPC-level code is code that handles input directly from the +network, and thus a high degree of memory safety and sanity checking +is needed to help ensure proper levels of security. Bugs in this +code can have significant impact on security and performance. + +However, it is code that is repetitive and tedious to write by hand. + +The C code generated by rpcgen makes extensive use of the facilities +of the user space TI-RPC library and libc. Furthermore, the dialect +of the generated code is very traditional K&R C. + +The Linux kernel's implementation of SunRPC-based protocols hand-roll +their XDR implementation. There are two main reasons for this: + +1. libtirpc (and its predecessors) operate only in user space. The + kernel's RPC implementation and its API are significantly + different than libtirpc. + +2. rpcgen-generated code is believed to be less efficient than code + that is hand-written. + +These days, gcc and its kin are capable of optimizing code better +than human authors. There are only a few instances where writing +XDR code by hand will make a measurable performance different. + +In addition, the current hand-written code in the Linux kernel is +difficult to audit and prove that it implements exactly what is in +the protocol specification. + +In order to accrue the benefits of machine-generated XDR code in the +kernel, a tool is needed that will output C code that works against +the kernel's SunRPC implementation rather than libtirpc. + +Enter xdrgen. + + +Dependencies +------------ + +These dependencies are typically packaged by Linux distributions: + +- python3 +- python3-lark +- python3-jinja2 + +These dependencies are available via PyPi: + +- pip install 'lark[interegular]' + + +XDR Specifications +------------------ + +When adding a new protocol implementation to the kernel, the XDR +specification can be derived by feeding a .txt copy of the RFC to +the script located in tools/net/sunrpc/extract.sh. + + $ extract.sh < rfc0001.txt > new2.x + + +Operation +--------- + +Once a .x file is available, use xdrgen to generate source and +header files containing an implementation of XDR encoding and +decoding functions for the specified protocol. + + $ ./xdrgen definitions new2.x > include/linux/sunrpc/xdrgen/new2.h + $ ./xdrgen declarations new2.x > new2xdr_gen.h + +and + + $ ./xdrgen source new2.x > new2xdr_gen.c + +The files are ready to use for a server-side protocol implementation, +or may be used as a guide for implementing these routines by hand. + +By default, the only comments added to this code are kdoc comments +that appear directly in front of the public per-procedure APIs. For +deeper introspection, specifying the "--annotate" flag will insert +additional comments in the generated code to help readers match the +generated code to specific parts of the XDR specification. + +Because the generated code is targeted for the Linux kernel, it +is tagged with a GPLv2-only license. + +The xdrgen tool can also provide lexical and syntax checking of +an XDR specification: + + $ ./xdrgen lint xdr/new.x + + +How It Works +------------ + +xdrgen does not use machine learning to generate source code. The +translation is entirely deterministic. + +RFC 4506 Section 6 contains a BNF grammar of the XDR specification +language. The grammar has been adapted for use by the Python Lark +module. + +The xdr.ebnf file in this directory contains the grammar used to +parse XDR specifications. xdrgen configures Lark using the grammar +in xdr.ebnf. Lark parses the target XDR specification using this +grammar, creating a parse tree. + +xdrgen then transforms the parse tree into an abstract syntax tree. +This tree is passed to a series of code generators. + +The generators are implemented as Python classes residing in the +generators/ directory. Each generator emits code created from Jinja2 +templates stored in the templates/ directory. + +The source code is generated in the same order in which they appear +in the specification to ensure the generated code compiles. This +conforms with the behavior of rpcgen. + +xdrgen assumes that the generated source code is further compiled by +a compiler that can optimize in a number of ways, including: + + - Unused functions are discarded (ie, not added to the executable) + + - Aggressive function inlining removes unnecessary stack frames + + - Single-arm switch statements are replaced by a single conditional + branch + +And so on. + + +Pragmas +------- + +Pragma directives specify exceptions to the normal generation of +encoding and decoding functions. Currently one directive is +implemented: "public". + +Pragma exclude +------ ------- + + pragma exclude ; + +In some cases, a procedure encoder or decoder function might need +special processing that cannot be automatically generated. The +automatically-generated functions might conflict or interfere with +the hand-rolled function. To avoid editing the generated source code +by hand, a pragma can specify that the procedure's encoder and +decoder functions are not included in the generated header and +source. + +For example: + + pragma exclude NFSPROC3_READDIRPLUS; + +Excludes the decoder function for the READDIRPLUS argument and the +encoder function for the READDIRPLUS result. + +Note that because data item encoder and decoder functions are +defined "static __maybe_unused", subsequent compilation +automatically excludes data item encoder and decoder functions that +are used only by excluded procedure. + +Pragma header +------ ------ + + pragma header ; + +Provide a name to use for the header file. For example: + + pragma header nlm4; + +Adds + + #include "nlm4xdr_gen.h" + +to the generated source file. + +Pragma public +------ ------ + + pragma public ; + +Normally XDR encoder and decoder functions are "static". In case an +implementer wants to call these functions from other source code, +s/he can add a public pragma in the input .x file to indicate a set +of functions that should get a prototype in the generated header, +and the function definitions will not be declared static. + +For example: + + pragma public nfsstat3; + +Adds these prototypes in the generated header: + + bool xdrgen_decode_nfsstat3(struct xdr_stream *xdr, enum nfsstat3 *ptr); + bool xdrgen_encode_nfsstat3(struct xdr_stream *xdr, enum nfsstat3 value); + +And, in the generated source code, both of these functions appear +without the "static __maybe_unused" modifiers. + + +Future Work +----------- + +Finish implementing XDR pointer and list types. + +Generate client-side procedure functions + +Expand the README into a user guide similar to rpcgen(1) + +Add more pragma directives: + + * @pages -- use xdr_read/write_pages() for the specified opaque + field + * @skip -- do not decode, but rather skip, the specified argument + field + +Enable something like a #include to dynamically insert the content +of other specification files + +Properly support line-by-line pass-through via the "%" decorator + +Build a unit test suite for verifying translation of XDR language +into compilable code + +Add a command-line option to insert trace_printk call sites in the +generated source code, for

I would prefer that the generated code be more deterministic: it enables a reader to better see exactly what has changed between runs of the tool. The problem is that Python sets are not ordered. I use a Python set to ensure that, when multiple procedures use a particular argument or result type, the encoder/decoder for that type is emitted only once. Sets aren't ordered, but I can use Python dictionaries for this purpose to ensure the procedure functions are always emitted in the same order if the .x file does not change.

Instead it declared an alias for the non-existent paes algorithm. The Crypto API will eventually try to load the paes algorithm, to construct the cbc(paes) instance. But because the module does not actually contain a "paes" algorithm, this will fail. Previously this failure was hidden and the the cbc(paes) lookup will be retried. This was fixed recently, thus exposing the buggy alias in paes_s390. Replace the bogus paes alias with aliases for the actual algorithms.

Previously, this was done with a simple check in the shrinker - "if btree node is in range being pinned, don't free it" - but this generated OOMs, as our shrinker wasn't well behaved if there was less memory available than expected. Instead, we now have two different shrinkers and lru lists; the second shrinker being for pinned nodes, with seeks set much higher than normal - so they can still be freed if necessary, but we'll prefer not to.

Convert all clk drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

A typical sequence do { seq = read_seqcount_begin(&s); } while (read_seqcount_retry(&s, seq); requires 13 cycles on an N1 Neoverse arm64 core (Ampere Altra, to be specific) for an empty loop. Two read memory barriers are needed. One for each of the seqcount_* functions. We can replace the first read barrier with a load acquire of the seqcount which saves us one barrier. On the Altra doing so reduces the cycle count from 13 to 8. According to ARM, this is a general improvement for the ARM64 architecture and not specific to a certain processor. See https://developer.arm.com/documentation/102336/0100/Load-Acquire-and-Store-Release-instructions "Weaker ordering requirements that are imposed by Load-Acquire and Store-Release instructions allow for micro-architectural optimizations, which could reduce some of the performance impacts that are otherwise imposed by an explicit memory barrier. If the ordering requirement is satisfied using either a Load-Acquire or Store-Release, then it would be preferable to use these instructions instead of a DMB" [ NOTE! This is my original minimal patch that unconditionally switches over to using smp_load_acquire(), instead of the much more involved and subtle patch that Christoph Lameter wrote that made it conditional. But Christoph gets authorship credit because I had initially thought that we needed the more complex model, and Christoph ran with it it and did the work. Only after looking at code generation for all the relevant architectures, did I come to the conclusion that nobody actually really needs the old "smp_rmb()" model. Even architectures without load-acquire support generally do as well or better with smp_load_acquire(). So credit to Christoph, but if this then causes issues on other architectures, put the blame solidly on me. Also note as part of the ruthless simplification, this gets rid of the overly subtle optimization where some code uses a non-barrier version of the sequence count (see the __read_seqcount_begin() users in fs/namei.c). They then play games with their own barriers and/or with nested sequence counts. Those optimizations are literally meaningless on x86, and questionable elsewhere. If somebody can show that they matter, we need to re-do them more cleanly than "use an internal helper". - Linus ] Signed-off-by: Christoph Lameter (Ampere) Link: https://lore.kernel.org/all/20240912-seq_optimize-v3-1-8ee25e04dffa@gentwo.org/ Signed-off-by: Linus Torvalds --- include/linux/seqlock.h | 25 +++++-------------------- 1 file changed, 5 insertions(+), 20 deletions(-) diff --git a/include/linux/seqlock.h b/include/linux/seqlock.h index d90d8ee29d81..fffeb754880f 100644 --- a/include/linux/seqlock.h +++ b/include/linux/seqlock.h @@ -157,7 +157,7 @@ __seqprop_##lockname##_const_ptr(const seqcount_##lockname##_t *s) \ static __always_inline unsigned \ __seqprop_##lockname##_sequence(const seqcount_##lockname##_t *s) \ { \ - unsigned seq = READ_ONCE(s->seqcount.sequence); \ + unsigned seq = smp_load_acquire(&s->seqcount.sequence); \ \ if (!IS_ENABLED(CONFIG_PREEMPT_RT)) \ return seq; \ @@ -170,7 +170,7 @@ __seqprop_##lockname##_sequence(const seqcount_##lockname##_t *s) \ * Re-read the sequence counter since the (possibly \ * preempted) writer made progress. \ */ \ - seq = READ_ONCE(s->seqcount.sequence); \ + seq = smp_load_acquire(&s->seqcount.sequence); \ } \ \ return seq; \ @@ -208,7 +208,7 @@ static inline const seqcount_t *__seqprop_const_ptr(const seqcount_t *s) static inline unsigned __seqprop_sequence(const seqcount_t *s) { - return READ_ONCE(s->sequence); + return smp_load_acquire(&s->sequence); } static inline bool __seqprop_preemptible(const seqcount_t *s) @@ -263,17 +263,9 @@ SEQCOUNT_LOCKNAME(mutex, struct mutex, true, mutex) #define seqprop_assert(s) __seqprop(s, assert)(s) /** - * __read_seqcount_begin() - begin a seqcount_t read section w/o barrier + * __read_seqcount_begin() - begin a seqcount_t read section * @s: Pointer to seqcount_t or any of the seqcount_LOCKNAME_t variants * - * __read_seqcount_begin is like read_seqcount_begin, but has no smp_rmb() - * barrier.

of the retransmit queue and then dereferencing that skb to get the skb_mstamp_ns value via tcp_skb_timestamp_us(skb). The crash is the same one that was reported a # of years ago here: https://lore.kernel.org/netdev/86c0f836-9a7c-438b-d81a-839be45f1f58@gmail.com/T/#t and the kernel we're running has the fix which was added to resolve this issue. Unfortunately we've been unsuccessful so far in reproducing this problem in the lab and do not have the luxury of pushing out a new kernel to try and test if newer kernels resolve this issue at the moment. I realize this is a report against both an Ubuntu kernel and also an older 5.4 kernel. I have reported this issue to Ubuntu here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077657 however I feel like since this issue has possibly cropped up again it makes sense to build in some protection in this path (even on the latest kernel versions) since the code in question just blindly assumes there's a valid skb without testing if it's NULL b/f it looks at the timestamp. Given we have seen crashes in this path before and now this case it seems like we should protect ourselves for when packets_out accounting is incorrect. While we should fix that root cause we should also just make sure the skb is not NULL before dereferencing it. Also add a warn once here to capture some information if/when the problem case is hit again.

Because after calling mmap, no data may be written, or only a small amount of data may be written to the head of the mmap area. This commit moves extending valid_size to exfat_page_mkwrite(). In exfat_page_mkwrite() only extend valid_size to the starting position of new data writing, which reduces unnecessary writing of zeros. If the block is not mapped and is marked as new after being mapped for writing, block_write_begin() will zero the page cache corresponding to the block, so there is no need to call zero_user_segment() in exfat_file_zeroed_range(). And after moving extending valid_size to exfat_page_mkwrite(), the data written by mmap will be copied to the page cache but the page cache may be not mapped to the disk. Calling zero_user_segment() will cause the data written by mmap to be cleared. So this commit removes calling zero_user_segment() from exfat_file_zeroed_range() and renames exfat_file_zeroed_range() to exfat_extend_valid_size().

Limiting 'PHYSMEM_END' to a 'phys_addr_t' (which is the same as 'resource_size_t') fixes the build, but Geert points out that it will then cause a silent overflow in mm/sparse.c: unsigned long max_sparsemem_pfn = (PHYSMEM_END + 1) >> PAGE_SHIFT; so we actually do want PHYSMEM_END to be defined a 64-bit type - just not all ones, and not larger than 'phys_addr_t'. The proper fix is probably to not have some kind of default fallback at all, but just make sure every architecture has a valid MAX_PHYSMEM_BITS. But in the meantime, this just applies the rule that PHYSMEM_END is the largest value that fits in a 'phys_addr_t', but does not have the high bit set in 64 bits. Ugly, ugly.

The only situation where it is defined but not exported is when the top-level Makefile is wrapped by another Makefile (e.g., GNUmakefile). I cannot think of any other use cases. I know some people use this tip to define custom variables. However, even in that case, you can export it directly in the wrapper Makefile.

When the kernel is built in the source tree, there is no ambiguity, as the output directory and the source directory are the same. If the kernel was built in a separate build directory, should be the kernel output directory. Otherwise, Kbuild cannot locate necessary build artifacts. This has been the method for building external modules against a pre-built kernel in a separate directory for over 20 years. [1] If you pass the kernel source directory to the -C option, you must also specify the kernel build directory using the O= option. This approach works as well, though it results in a slightly longer command: $ make -C O= M= Some people mistakenly believe that O= should specify a build directory for external modules when used together with M=.

I have evidence of an Linux NFS client getting NFS4ERR_BAD_SEQID to a v4.0 LOCK request to a Linux server (which had fixed the problem with RELEASE_LOCKOWNER bug fixed). The LOCK request presented a "new" lock owner so there are two seq ids in the request: that for the open file, and that for the new lock. Given the context I am confident that the new lock owner was reported to have the wrong seqid. As lock owner identifiers are reused, the server must still have a lock owner active which the client thinks is no longer active. I wasn't able to determine a root-cause but the simplest fix seems to be to ensure lock owners are always unique much as open owners are (thanks to a time stamp). The easiest way to ensure uniqueness is with a 64bit counter for each server. That will never cycle (if updated once a nanosecond the last 584 years. A single NFS server would not handle open/lock requests nearly that fast, and a Linux node is unlikely to have an uptime approaching that). This patch removes the 2 ida and instead uses a per-server atomic64_t to provide uniqueness. Note that the lock owner already encodes the id as 64 bits even though it is a 32bit value. So changing to a 64bit value does not change the encoding of the lock owner. The open owner encoding is now 4 bytes larger.

Thus, we should look that the server supports proxying of times via OPEN4_SHARE_ACCESS_WANT_DELEG_TIMESTAMPS. We want to be extra pedantic and continue to check that FATTR4_TIME_DELEG_ACCESS and FATTR4_TIME_DELEG_MODIFY are set. The server needs to expose both for the client to correctly detect "Proxying of Times" support.

However, if these applications want non-aligned offsets and sizes they need to either use locks or risk data corruption, as the NFS client defaults to extending writes to whole pages. This commit adds a new mount option `noalignwrite`, which allows to turn that off and avoid the need of locking, as long as these applications don't overlap on offsets.

The about-to-be-introduced LOCALIO use case sometimes has no svc_rqst context, so this logic won't work in that case. Instead, examine the passed-in file handle.

So it is safe to call __fh_verify() with a NULL rqstp, but the net, cred, and client args must not be NULL. __fh_verify() does not use SVC_NET(), nor does the functions it calls. Rather than using rqstp->rq_client pass the client and gssclient explicitly to __fh_verify and then to nfsd_set_fh_dentry(). Lastly, it should be noted that the previous commit prepared for 4 associated tracepoints to only be used if rqstp is not NULL (this is a stop-gap that should be properly fixed so localio also benefits from the utility these tracepoints provide when debugging fh_verify issues).

From c63f0e48febfaea8a3cd4146abda9cc7a329b0e3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 5 Sep 2024 15:09:43 -0400 Subject: [PATCH 2492/2648] nfsd: add nfsd_file_acquire_local() nfsd_file_acquire_local() can be used to look up a file by filehandle without having a struct svc_rqst. This can be used by NFS LOCALIO to allow the NFS client to bypass the NFS protocol to directly access a file provided by the NFS server which is running in the same kernel. In nfsd_file_do_acquire() care is taken to always use fh_verify() if rqstp is not NULL (as is the case for non-LOCALIO callers). Otherwise the non-LOCALIO callers will not supply the correct and required arguments to __fh_verify (e.g. gssclient isn't passed). Introduce fh_verify_local() wrapper around __fh_verify to make it clear that LOCALIO is intended caller. Also, use GC for nfsd_file returned by nfsd_file_acquire_local. GC offers performance improvements if/when a file is reopened before launderette cleans it from the filecache's LRU.

The former was needed for the first revision of the LOCALIO protocol which had an RPC that took a void arg: /* raw RFC 9562 UUID */ typedef u8 uuid_t; program NFS_LOCALIO_PROGRAM { version LOCALIO_V1 { void NULL(void) = 0; uuid_t GETUUID(void) = 1; } = 1; } = 400122; The latter is needed for the final revision of the LOCALIO protocol which has a UUID_IS_LOCAL RPC which returns a void: /* raw RFC 9562 UUID */ typedef u8 uuid_t; program NFS_LOCALIO_PROGRAM { version LOCALIO_V1 { void NULL(void) = 0; void UUID_IS_LOCAL(uuid_t) = 1; } = 1; } = 400122; There is really no value in triggering a BUG_ON in response to either of these previously unsupported conditions. NeilBrown would like the entire 'if (proc->p_proc != 0)' branch removed (not just the one BUG_ON that must be removed for LOCALIO's immediate needs of returning void).

This is needed by the localio code to map nfs client creds to nfs server credentials. Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that ->fsuid and ->fsgid must be used (rather than ->uid and ->gid). In addition, these uid and gid must be translated with from_kuid_munged() so local client uses correct uid and gid when acting as local server. Jeff Layton noted: This is where the magic happens. Since we're working in kuid_t/kgid_t, we don't need to worry about further idmapping.

This commit also provides the base nfs_uuid_t interfaces to allow proper net namespace refcounting for the LOCALIO use case. CONFIG_NFS_LOCALIO controls the nfs_common, NFS server and NFS client enablement for LOCALIO. If both NFS_FS=m and NFSD=m then NFS_COMMON_LOCALIO_SUPPORT=m and nfs_localio.ko is built (and provides nfs_common's LOCALIO support). # lsmod | grep nfs_localio nfs_localio 12288 2 nfsd,nfs sunrpc 745472 35 nfs_localio,nfsd,auth_rpcgss,lockd,nfsv3,nfs Signed-off-by: Mike Snitzer Co-developed-by: NeilBrown Signed-off-by: NeilBrown Reviewed-by: Jeff Layton Signed-off-by: Anna Schumaker --- fs/Kconfig | 23 ++++++++ fs/nfs_common/Makefile | 3 + fs/nfs_common/nfslocalio.c | 116 +++++++++++++++++++++++++++++++++++++ include/linux/nfslocalio.h | 36 ++++++++++++ 4 files changed, 178 insertions(+) create mode 100644 fs/nfs_common/nfslocalio.c create mode 100644 include/linux/nfslocalio.h diff --git a/fs/Kconfig b/fs/Kconfig index a46b0cbc4d8f..24d4e4b419d1 100644 --- a/fs/Kconfig +++ b/fs/Kconfig @@ -382,6 +382,29 @@ config NFS_COMMON depends on NFSD || NFS_FS || LOCKD default y +config NFS_COMMON_LOCALIO_SUPPORT + tristate + default n + default y if NFSD=y || NFS_FS=y + default m if NFSD=m && NFS_FS=m + select SUNRPC + +config NFS_LOCALIO + bool "NFS client and server support for LOCALIO auxiliary protocol" + depends on NFSD && NFS_FS + select NFS_COMMON_LOCALIO_SUPPORT + default n + help + Some NFS servers support an auxiliary NFS LOCALIO protocol + that is not an official part of the NFS protocol. + + This option enables support for the LOCALIO protocol in the + kernel's NFS server and client.

This commit exposes LOCALIO's required NFSD symbols to the NFS client: - Make nfsd_open_local_fh() symbol and other required NFSD symbols available to NFS in a global 'nfs_to' nfsd_localio_operations struct (global access suggested by Trond, nfsd_localio_operations suggested by NeilBrown). The next commit will also introduce nfsd_localio_ops_init() that init_nfsd() will call to initialize 'nfs_to'. - Introduce nfsd_file_file() that provides access to nfsd_file's backing file. Keeps nfsd_file structure opaque to NFS client (as suggested by Jeff Layton). - Introduce nfsd_file_put_local() that will put the reference to the nfsd_file's associated nn->nfsd_serv and then put the reference to the nfsd_file (as suggested by NeilBrown).

This is only useful when both the client and server are running on the same host. If nfsd_open_local_fh() fails then the NFS client will both retry and fallback to normal network-based read, write and commit operations if localio is no longer supported. Care is taken to ensure the same NFS security mechanisms are used (authentication, etc) regardless of whether localio or regular NFS access is used. The auth_domain established as part of the traditional NFS client access to the NFS server is also used for localio. Store auth_domain for localio in nfsd_uuid_t and transfer it to the client if it is local to the server. Relative to containers, localio gives the client access to the network namespace the server has. This is required to allow the client to access the server's per-namespace nfsd_net struct. This commit also introduces the use of NFSD's percpu_ref to interlock nfsd_destroy_serv and nfsd_open_local_fh, to ensure nn->nfsd_serv is not destroyed while in use by nfsd_open_local_fh and other LOCALIO client code. CONFIG_NFS_LOCALIO enables NFS server support for LOCALIO.

The server expects this protocol to use the same transport as NFS and NFSACL for its RPCs. This protocol isn't part of an IETF standard, nor does it need to be considering it is Linux-to-Linux auxiliary RPC protocol that amounts to an implementation detail. The UUID_IS_LOCAL method encodes the client generated uuid_t in terms of the fixed UUID_SIZE (16 bytes). The fixed size opaque encode and decode XDR methods are used instead of the less efficient variable sized methods.

This is only useful when the client and the server are running on the same host. nfs_local_probe() is stubbed out, later commits will enable client and server handshake via a Linux-only LOCALIO auxiliary RPC protocol. This has dynamic binding with the nfsd module (via nfs_localio module which is part of nfs_common). LOCALIO will only work if nfsd is already loaded. The "localio_enabled" nfs kernel module parameter can be used to disable and enable the ability to use LOCALIO support. CONFIG_NFS_LOCALIO enables NFS client support for LOCALIO. Lastly, LOCALIO uses an nfsd_file to initiate all IO. To make proper use of nfsd_file (and nfsd's filecache) its lifetime (duration before nfsd_file_put is called) must extend until after commit, read and write operations. So rather than immediately drop the nfsd_file reference in nfs_local_open_fh(), that doesn't happen until nfs_local_pgio_release() for read/write and not until nfs_local_release_commit_data() for commit. The same applies to the reference held on nfsd's nn->nfsd_serv. Both objects' lifetimes and associated references are managed through calls to nfs_to->nfsd_file_put_local().

Instead of risking running over due to the extra overhead from the NFS stack, we should just call these routines from a workqueue job. Since we need to do this to address 1) above we're able to avoid possibly blowing the stack "for free". Use of dedicated workqueues improves performance over using the system_unbound_wq. Also, the creds used to open the file are used to override_creds() in both nfs_local_call_read() and nfs_local_call_write() -- otherwise the workqueue could have elevated capabilities (which the caller may not). Lastly, care is taken to set PF_LOCAL_THROTTLE | PF_MEMALLOC_NOIO in nfs_do_local_write() to avoid writeback deadlocks. The PF_LOCAL_THROTTLE flag prevents deadlocks in balance_dirty_pages() by causing writes to only be throttled against other writes to the same bdi (it keeps the throttling local). Normally all writes to bdi(s) are throttled equally (after throughput factors are allowed for). The PF_MEMALLOC_NOIO flag prevents the lower filesystem IO from causing memory reclaim to re-enter filesystems or IO devices and so prevents deadlocks from occuring where IO that cleans pages is waiting on IO to complete.

If matched, the NFS server populates members in the nfs_uuid_t struct. The NFS client then transfers these nfs_uuid_t struct member pointers to the nfs_client struct and cleans up the nfs_uuid_t struct. See: fs/nfs/localio.c:nfs_local_probe() This protocol isn't part of an IETF standard, nor does it need to be considering it is Linux-to-Linux auxiliary RPC protocol that amounts to an implementation detail. Localio is only supported when UNIX-style authentication (AUTH_UNIX, aka AUTH_SYS) is used (enforced by fs/nfs/localio.c:nfs_local_probe()). The UUID_IS_LOCAL method encodes the client generated uuid_t in terms of the fixed UUID_SIZE (16 bytes). The fixed size opaque encode and decode XDR methods are used instead of the less efficient variable sized methods. Having a nonce (single-use uuid) is better than using the same uuid for the life of the server, and sending it proactively by client rather than reactively by the server is also safer.

The NFS client then uses nfs_common to +transfer the nfs_uuid_t from its nfs_uuids to the nn->nfsd_serv +clients_list from the nfs_common's uuids_list. See: +fs/nfs/localio.c:nfs_local_probe() + +nfs_common's nfs_uuids list is the basis for LOCALIO enablement, as such +it has members that point to nfsd memory for direct use by the client +(e.g. 'net' is the server's network namespace, through it the client can +access nn->nfsd_serv with proper rcu read access). It is this client +and server synchronization that enables advanced usage and lifetime of +objects to span from the host kernel's nfsd to per-container knfsd +instances that are connected to nfs client's running on the same local +host. + +NFS Client issues IO instead of Server +====================================== + +Because LOCALIO is focused on protocol bypass to achieve improved IO +performance, alternatives to the traditional NFS wire protocol (SUNRPC +with XDR) must be provided to access the backing filesystem. + +See fs/nfs/localio.c:nfs_local_open_fh() and +fs/nfsd/localio.c:nfsd_open_local_fh() for the interface that makes +focused use of select nfs server objects to allow a client local to a +server to open a file pointer without needing to go over the network. + +The client's fs/nfs/localio.c:nfs_local_open_fh() will call into the +server's fs/nfsd/localio.c:nfsd_open_local_fh() and carefully access +both the associated nfsd network namespace and nn->nfsd_serv in terms of +RCU. If nfsd_open_local_fh() finds that the client no longer sees valid +nfsd objects (be it struct net or nn->nfsd_serv) it returns -ENXIO +to nfs_local_open_fh() and the client will try to reestablish the +LOCALIO resources needed by calling nfs_local_probe() again. This +recovery is needed if/when an nfsd instance running in a container were +to reboot while a LOCALIO client is connected to it. + +Once the client has an open nfsd_file pointer it will issue reads, +writes and commits directly to the underlying local filesystem (normally +done by the nfs server). As such, for these operations, the NFS client +is issuing IO to the underlying local filesystem that it is sharing with +the NFS server. See: fs/nfs/localio.c:nfs_local_doio() and +fs/nfs/localio.c:nfs_local_commit(). + +Security +======== + +Localio is only supported when UNIX-style authentication (AUTH_UNIX, aka +AUTH_SYS) is used. + +Care is taken to ensure the same NFS security mechanisms are used +(authentication, etc) regardless of whether LOCALIO or regular NFS +access is used. The auth_domain established as part of the traditional +NFS client access to the NFS server is also used for LOCALIO. + +Relative to containers, LOCALIO gives the client access to the network +namespace the server has. This is required to allow the client to access +the server's per-namespace nfsd_net struct. With traditional NFS, the +client is afforded this same level of access (albeit in terms of the NFS +protocol via SUNRPC).

What are the use cases for LOCALIO? + + a. Workloads where the NFS client and server are on the same host + realize improved IO performance. In particular, it is common when + running containerised workloads for jobs to find themselves + running on the same host as the knfsd server being used for + storage. + +2. What are the requirements for LOCALIO? + + a. Bypass use of the network RPC protocol as much as possible. This + includes bypassing XDR and RPC for open, read, write and commit + operations. + b. Allow client and server to autonomously discover if they are + running local to each other without making any assumptions about + the local network topology. + c. Support the use of containers by being compatible with relevant + namespaces (e.g. network, user, mount). + d. Support all versions of NFS. NFSv3 is of particular importance + because it has wide enterprise usage and pNFS flexfiles makes use + of it for the data path. + +3. Why doesn’t LOCALIO just compare IP addresses or hostnames when + deciding if the NFS client and server are co-located on the same + host? + + Since one of the main use cases is containerised workloads, we cannot + assume that IP addresses will be shared between the client and + server. This sets up a requirement for a handshake protocol that + needs to go over the same connection as the NFS traffic in order to + identify that the client and the server really are running on the + same host. The handshake uses a secret that is sent over the wire, + and can be verified by both parties by comparing with a value stored + in shared kernel memory if they are truly co-located. + +4. Does LOCALIO improve pNFS flexfiles? + + Yes, LOCALIO complements pNFS flexfiles by allowing it to take + advantage of NFS client and server locality. Policy that initiates + client IO as closely to the server where the data is stored naturally + benefits from the data path optimization LOCALIO provides. + +5. Why not develop a new pNFS layout to enable LOCALIO? + + A new pNFS layout could be developed, but doing so would put the + onus on the server to somehow discover that the client is co-located + when deciding to hand out the layout. + There is value in a simpler approach (as provided by LOCALIO) that + allows the NFS client to negotiate and leverage locality without + requiring more elaborate modeling and discovery of such locality in a + more centralized manner. + +6. Why is having the client perform a server-side file OPEN, without + using RPC, beneficial? Is the benefit pNFS specific? + + Avoiding the use of XDR and RPC for file opens is beneficial to + performance regardless of whether pNFS is used. Especially when + dealing with small files its best to avoid going over the wire + whenever possible, otherwise it could reduce or even negate the + benefits of avoiding the wire for doing the small file I/O itself. + Given LOCALIO's requirements the current approach of having the + client perform a server-side file open, without using RPC, is ideal. + If in the future requirements change then we can adapt accordingly. + +7. Why is LOCALIO only supported with UNIX Authentication (AUTH_UNIX)? + + Strong authentication is usually tied to the connection itself. It + works by establishing a context that is cached by the server, and + that acts as the key for discovering the authorisation token, which + can then be passed to rpc.mountd to complete the authentication + process. On the other hand, in the case of AUTH_UNIX, the credential + that was passed over the wire is used directly as the key in the + upcall to rpc.mountd. This simplifies the authentication process, and + so makes AUTH_UNIX easier to support. + +8. How do export options that translate RPC user IDs behave for LOCALIO + operations (eg. root_squash, all_squash)? + + Export options that translate user IDs are managed by nfsd_setuser() + which is called by nfsd_setuser_and_check_port() which is called by + __fh_verify(). So they get handled exactly the same way for LOCALIO + as they do for non-LOCALIO. + RPC === From 736cd2c1ae7f911df9aae0e647899b49bdbccdb8 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 5 Sep 2024 15:10:00 -0400 Subject: [PATCH 2509/2648] nfs: add "NFS Client and Server Interlock" section to localio.rst This section answers a new FAQ entry: 9.

Without this patch, there are no user interfaces of vulnerabilities to check on LoongArch. The output of those files reflects the state of the CPUs in the system, the output value "Not affected" means "CPU is not affected by the vulnerability".

Theoretically, in order to completely avoid spurious page fault we need a "dbar + ibar" pair between the page table modifications and the subsequent memory accesses using the corresponding virtual address. But "ibar" is too heavy for performace, so we only use a "dbar 0b11000" in set_pte(). And let spurious_fault() filter the rest rare spurious page faults which should be avoided by "ibar". Besides, we replace the llsc loop with amo in set_pte() which has better performace, and refactor mmu_context.h to 1) avoid any load/store/branch instructions between the writing of CSR.ASID & CSR.PGDL, 2) ensure flush tlb operation is after updating ASID.

However, percpu infrastructure expects its leaf definitions to encode the size of their percpu variable, so the patch merges all the asm clauses from the static inline function into the corresponding leaf macros. The secondary effect of this change is to avoid explicit __percpu annotations for function arguments. Currently, __percpu macro is defined in include/linux/compiler_types.h, but with proposed patch [1], __percpu definition will need macros from include/asm-generic/percpu.h, creating forward dependency loop. The proposed solution is the same as x86 architecture uses.

However, both callers revert the advancement (although receive_encrypted_read() zeros beyond the iterator first). The problem is, though, that cifs_readv_receive() reverts by the original length, not the amount transmitted which can cause an oops in iov_iter_revert(). Fix this by: (1) Remove the iov_iter_advance() from cifs_read_iter_from_socket(). (2) Remove the iov_iter_revert() from both callers. This fixes the bug in cifs_readv_receive(). (3) In receive_encrypted_read(), if we didn't get back as much data as the buffer will hold, copy the iterator, advance the copy and use the copy to drive iov_iter_zero(). As a bonus, this gets rid of some unnecessary work. This was triggered by generic/074 with the "-o sign" mount option.

That's due to the fact that the throttle semaphore can sleep but the async API can't. This patch allows throttling in the async API by using the tentative variant of the semaphore and upon failure (semaphore at 0) returns EBUSY to signal to the caller that they need to wait for the completion of previously issued commands.

Building up on previous changes that converted vq operations to the async api, this patch parallelizes the device suspend: 1) Suspend all active vqs parallel. 2) Query suspended vqs in parallel. For 1 vDPA device x 32 VQs (16 VQPs) attached to a large VM (256 GB RAM, 32 CPUs x 2 threads per core), the device suspend time is reduced from ~37 ms to ~13 ms. A later patch will remove the link unregister operation which will make it even faster.

This change switches to parallel suspend/resume. When increasing the number of queues the flow has changed a bit for simplicity: the setup_vq() function will always be called before resume_vqs(). If the VQ is initialized, setup_vq() will exit early. If the VQ is not initialized, setup_vq() will create it and resume_vqs() will resume it.

This enhancement allows users to query information about these queues. Specifically, add two sysfs entries: 1. Queue name: Provides the name of each queue (e.g. hiprio/requests.8). 2. CPU list: Shows the list of CPUs that can process requests for each queue. The CPU list feature is inspired by similar functionality in the block MQ layer, which provides analogous sysfs entries for block devices. These new sysfs entries will improve observability and aid in debugging and performance tuning of Virtio FS devices.

MR deletion is about 30-40% the time of MR creation. As deleting the old MR is not important for the process of setting up the new MR, this operation can be postponed. This series adds a workqueue that does MR garbage collection at a later point. If the MR lock is taken, the handler will back off and reschedule. The exception during shutdown: then the handler must not postpone the work.

This increases the chance of batching, but also introduces a lot of latency into the communication. So we can optimize this path by adding a fast path to be taken when there is no element in the intermediate queue, there is space available in the virtqueue, and no other process that is sending packets (tx_lock held). The following benchmarks were run to check improvements in latency and throughput. The test bed is a host with Intel i7-10700KF CPU @ 3.80GHz and L1 guest running on QEMU/KVM with vhost process and all vCPUs pinned individually to pCPUs. - Latency Tool: Fio version 3.37-56 Mode: pingpong (h-g-h) Test runs: 50 Runtime-per-test: 50s Type: SOCK_STREAM In the following fio benchmark (pingpong mode) the host sends a payload to the guest and waits for the same payload back. fio process pinned both inside the host and the guest system.

The kernel is loaded at that physical address inside the VM by the VMM software (Xen/QEMU). When running a Xen PVH Dom0, the host reserved addresses are mapped 1-1 into the PVH container. There exist system firmwares (Coreboot/EDK2) with reserved memory at 16MB. This creates a conflict where the PVH kernel cannot be loaded at that address. Modify the PVH entrypoint to be position-indepedent to allow flexibility in load address. Only the 64bit entry path is converted. A 32bit kernel is not PIC, so calling into other parts of the kernel, like xen_prepare_pvh() and mk_pgtable_32(), don't work properly when relocated. This makes the code PIC, but the page tables need to be updated as well to handle running from the kernel high map. The UNWIND_HINT_END_OF_STACK is to silence: vmlinux.o: warning: objtool: pvh_start_xen+0x7f: unreachable instruction after the lret into 64bit code.

For a 64bit kernel, the entry point must switch to 64bit mode, which requires a set of page tables. In the past, PVH used init_top_pgt. This works fine when the kernel is loaded at LOAD_PHYSICAL_ADDR, as the page tables are prebuilt for this address. If the kernel is loaded at a different address, they need to be adjusted. __startup_64() adjusts the prebuilt page tables for the physical load address, but it is 64bit code. The 32bit PVH entry code can't call it to adjust the page tables, so it can't readily be re-used. 64bit PVH entry needs page tables set up for identity map, the kernel high map and the direct map. pvh_start_xen() enters identity mapped. Inside xen_prepare_pvh(), it jumps through a pv_ops function pointer into the highmap. The direct map is used for __va() on the initramfs and other guest physical addresses. Add a dedicated set of prebuild page tables for PVH entry. They are adjusted in assembly before loading. Add XEN_ELFNOTE_PHYS32_RELOC to indicate support for relocation along with the kernel's loading constraints. The maximum load address, KERNEL_IMAGE_SIZE - 1, is determined by a single pvh_level2_ident_pgt page. It could be larger with more pages.

But for small packets, a mismatched address without VIRTNET_RX_PAD and xdp_headroom is used for unmapping. That will result in unsynchronized buffers when SWIOTLB is enabled, for example, when running as a TDX guest. This patch unifies the address passed to the virtio core as the address of the virtnet header and fixes the mismatched buffer address. Changes from v2: unify the buf that passed to the virtio core in small and merge mode. Changes from v1: Use ctx to get xdp_headroom.

Example: INITIATOR -> NAT/PAT -> RESPONDER Initiator passes through NAT/PAT ("us") and SNAT is done (saddr rewrite). Then, later, NAT/PAT machine itself also wants to connect to RESPONDER. This will not work if the SNAT done earlier has same IP:PORT source pair. Conntrack table has: ORIGINAL: $IP_INITATOR:$SPORT -> $IP_RESPONDER:$DPORT REPLY: $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT and new locally originating connection wants: ORIGINAL: $IP_NAT:$SPORT -> $IP_RESPONDER:$DPORT REPLY: $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT This is handled by the NAT engine which will do a source port reallocation for the locally originating connection that is colliding with an existing tuple by attempting a source port rewrite. This is done even if this new connection attempt did not go through a masquerade/snat rule. There is a rare race condition with connection-less protocols like UDP, where we do the port reallocation even though its not needed. This happens when new packets from the same, pre-existing flow are received in both directions at the exact same time on different CPUs after the conntrack table was flushed (or conntrack becomes active for first time). With strict ordering/single cpu, the first packet creates new ct entry and second packet is resolved as established reply packet. With parallel processing, both packets are picked up as new and both get their own ct entry. In this case, the 'reply' packet (picked up as ORIGINAL) can be mangled by NAT engine because a port collision is detected. This change isn't enough to prevent a packet drop later during nf_conntrack_confirm(), the existing clash resolution strategy will not detect such reverse clash case.

Permit this by checking if the colliding entry matches the reply direction. Happens when both ends send packets at same time, both requests are picked up as NEW, rather than NEW for the 'first' and 'ESTABLISHED' for the second packet. This is an esoteric condition, as ruleset must permit NEW connections in either direction and both peers must already have a bidirectional traffic flow at the time conntrack gets enabled. Allow the 'reverse' skb to pass and assign the existing (clashing) entry. While at it, also drop the extra 'dying' check, this is already tested earlier by the calling function.

The selftests represent the most common scenarios and can also be used as selfdocumentation of the feature. UDP and TCP testcases are split in different files because of the different nature of the protocols, specially due to the challenges that present to reliable test UDP due to the connectionless nature of the protocol. UDP only covers the scenarios involving the prerouting hook. The UDP tests are signfinicantly slower than the TCP ones, hence they use a larger timeout, it takes 20 seconds to run the full UDP suite on a 48 vCPU Intel(R) Xeon(R) CPU @2.60GHz.

However, this is not necessary as each of these functions will always return 0 if CONFIG_NF_CONNTRACK_LABELS is not defined as each function starts with the equivalent of: struct nf_conn_labels *labels = nf_ct_labels_find(ct); if (!labels) return 0; And nf_ct_labels_find always returns NULL if CONFIG_NF_CONNTRACK_LABELS is not enabled.

See commit 368982cd7d1b ("netfilter: nfnetlink_queue: resolve clash for unconfirmed conntracks") for details. One problem is that nf_reroute() won't take an action if the queueing doesn't occur in the OUTPUT hook, i.e. when queueing in forward or postrouting, packet will be sent via the wrong path. Another problem is that the scenario addressed (2nd UDP packet sent with identical addresses while first packet is still being processed) can also occur without any nfqueue involvement due to threaded resolvers doing A and AAAA requests back-to-back. This lead us to add clash resolution logic to the conntrack core, see commit 6a757c07e51f ("netfilter: conntrack: allow insertion of clashing entries"). Instead of fixing the nfqueue based logic, lets remove it and let conntrack core handle this instead. Retain the ->update hook for sake of nfqueue based conntrack helpers. We could axe this hook completely but we'd have to split confirm and helper logic again, see commit ee04805ff54a ("netfilter: conntrack: make conntrack userspace helpers work again"). This SHOULD NOT be backported to kernels earlier than v5.6; they lack adequate clash resolution handling. Patch was originally written by Pablo Neira Ayuso.

In theory, this could be used to subvert security, because an attacker can create sectors that return error with the Write Uncorrectable command. Some programs may misbehave if they have to deal with EIO. This commit fixes dm-verity, so that if "panic_on_corruption" or "restart_on_corruption" was specified and an I/O error happens, the machine will panic or restart. This commit also changes kernel_restart to emergency_restart - kernel_restart calls reboot notifiers and these reboot notifiers may wait for the bio that failed. emergency_restart doesn't call the notifiers.

Unfortunately, that evaluates to true if there is no NR_CPUS configuration option. This results in CONFIG_SPLIT_PTE_PTLOCKS=y for mac_defconfig. This in turn causes the m68k "q800" and "virt" machines to crash in qemu if debugging options are enabled. Making CONFIG_SPLIT_PTE_PTLOCKS dependent on the existence of NR_CPUS does not work since a dependency on the existence of a numeric Kconfig entry always evaluates to false. Example: config HAVE_NO_NR_CPUS def_bool y depends on !NR_CPUS After adding this to a Kconfig file, "make defconfig" includes: $ grep NR_CPUS .config CONFIG_NR_CPUS=64 CONFIG_HAVE_NO_NR_CPUS=y Defining NR_CPUS for m68k does not help either since many architectures define NR_CPUS only for SMP configurations. Make SPLIT_PTE_PTLOCKS depend on SMP instead to solve the problem.

This patch (of 5): memfd_pin_folios on memory backed by THP panics if the requested start offset is not huge page aligned: BUG: kernel NULL pointer dereference, address: 0000000000000036 RIP: 0010:filemap_get_folios_contig+0xdf/0x290 RSP: 0018:ffffc9002092fbe8 EFLAGS: 00010202 RAX: 0000000000000002 RBX: 0000000000000002 RCX: 0000000000000002 The fault occurs here, because xas_load returns a folio with value 2: filemap_get_folios_contig() for (folio = xas_load(&xas); folio && xas.xa_index <= end; folio = xas_next(&xas)) { ... if (!folio_try_get(folio)) <-- BOOM "2" is an xarray sibling entry. We get it because memfd_pin_folios does not round the indices passed to filemap_get_folios_contig to huge page boundaries for THP, so we load from the middle of a huge page range see a sibling. (It does round for hugetlbfs, at the is_file_hugepages test). To fix, if the folio is a sibling, then return the next index as the starting point for the next call to filemap_get_folios_contig.

The issue was in the reflink workfow while reserving space for inline xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the time this function is called the reflink tree is already recreated at the destination inode from the source inode. At this point, this function reserves space for inline xattrs at the destination inode without even checking if there is space at the root metadata block. It simply reduces the l_count from 243 to 227 thereby making space of 256 bytes for inline xattr whereas the inode already has extents beyond this index (in this case up to 230), thereby causing corruption. The fix for this is to reserve space for inline metadata at the destination inode before the reflink tree gets recreated. The customer has verified the fix.

In order to silence the warning on LoongArch, specify the attribute like ".rodata..c_jump_table,\"a\",@progbits #" explicitly, then the section attribute of ".rodata..c_jump_table" must be readonly in the kernel/bpf/core.o file.

So the error log will trigger the above uninit-value access. The error log is out-of-date since get_blocks() was removed long time ago. And the error code will be logged in ocfs2_extent_map_get_blocks() once ocfs2_get_cluster() fails, so fix this by only logging inode and block.
