+Subject: [PATCH] yylex: Make lexer fatal errors actually be fatal
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When presented with a command that can't be tokenized to anything
+smaller than YYLMAX characters, the parser calls YY_FATAL_ERROR(errmsg),
+expecting that will stop further processing, as such:
+
+  #define YY_DO_BEFORE_ACTION \
+        yyg->yytext_ptr = yy_bp; \
+        yyleng = (int) (yy_cp - yy_bp); \
+        yyg->yy_hold_char = *yy_cp; \
+        *yy_cp = '\0'; \
+        if ( yyleng >= YYLMAX ) \
+                YY_FATAL_ERROR( "token too large, exceeds YYLMAX" ); \
+        yy_flex_strncpy( yytext, yyg->yytext_ptr, yyleng + 1 , yyscanner); \
+        yyg->yy_c_buf_p = yy_cp;
+
+The code flex generates expects that YY_FATAL_ERROR() will either return
+for it or do some form of longjmp(), or handle the error in some way at
+least, and so the strncpy() call isn't in an "else" clause, and thus if
+YY_FATAL_ERROR() is *not* actually fatal, it does the call with the
+questionable limit, and predictable results ensue.
+
+Unfortunately, our implementation of YY_FATAL_ERROR() is:
+
+   #define YY_FATAL_ERROR(msg)                     \
+     do {                                          \
+       grub_printf (_("fatal error: %s\n"), _(msg));     \
+     } while (0)
+
+The same pattern exists in yyless(), and similar problems exist in users
+of YY_INPUT(), several places in the main parsing loop,
+yy_get_next_buffer(), yy_load_buffer_state(), yyensure_buffer_stack,
+yy_scan_buffer(), etc.
+
+All of these callers expect YY_FATAL_ERROR() to actually be fatal, and
+the things they do if it returns after calling it are wildly unsafe.

+Subject: [PATCH] safemath: Add some arithmetic primitives that check for
+ overflow
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds a new header, include/grub/safemath.h, that includes easy to
+use wrappers for __builtin_{add,sub,mul}_overflow() declared like:
+
+  bool OP(a, b, res)
+
+where OP is grub_add, grub_sub or grub_mul. OP() returns true in the
+case where the operation would overflow and res is not modified.
+Otherwise, false is returned and the operation is executed.
+
+These arithmetic primitives require newer compiler versions. So, bump
+these requirements in the INSTALL file too.

+Content-Transfer-Encoding: 8bit
+
+The GRUB font file can have one NAME section only. Though if somebody
+crafts a broken font file with many NAME sections and loads it then the
+GRUB leaks memory. So, prevent against that by loading first NAME
+section and failing in controlled way on following one.

+Content-Transfer-Encoding: 8bit
+
+The two dimensional array p->posSlotEncoder[4][64] is being dereferenced
+using the GetLenToPosState() macro which checks if len is less than 5,
+and if so subtracts 2 from it. If len = 0, that is 0 - 2 = 4294967294.
+Obviously we don't want to dereference that far out so we check if the
+position found is greater or equal kNumLenToPosStates (4) and bail out.
+
+N.B.: Upstream LZMA 18.05 and later has this function completely rewritten
+without any history.

+Subject: [PATCH] term: Fix overflow on user inputs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This requires a very weird input from the serial interface but can cause
+an overflow in input_buf (keys) overwriting the next variable (npending)
+with the user choice:
+
+(pahole output)
+
+struct grub_terminfo_input_state {
+        int                        input_buf[6];         /*     0    24 */
+        int                        npending;             /*    24     4 */ <- CORRUPT
+        ...snip...
+
+The magic string requires causing this is "ESC,O,],0,1,2,q" and we overflow
+npending with "q" (aka increase npending to 161). The simplest fix is to
+just to disallow overwrites input_buf, which exactly what this patch does.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There is not need to reassemble the order of blocks. Per RFC 1350,
+server must wait for the ACK, before sending next block. Data packets
+can be served immediately without putting them to priority queue.
+
+Logic to handle incoming packet is this:
+  - if packet block id equal to expected block id, then
+    process the packet,
+  - if packet block id is less than expected - this is retransmit
+    of old packet, then ACK it and drop the packet,
+  - if packet block id is more than expected - that shouldn't
+    happen, just drop the packet.
+
+It makes the tftp receive path code simpler, smaller and faster.
+As a benefit, this change fixes CID# 73624 and CID# 96690, caused
+by following while loop:
+
+  while (cmp_block (grub_be_to_cpu16 (tftph->u.data.block), data->block + 1) == 0)
+
+where tftph pointer is not moving from one iteration to another, causing
+to serve same packet again. Luckily, double serving didn't happen due to
+data->block++ during the first iteration.
+
+Fixes: CID 73624, CID 96690

+ max_addr against integer underflow
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit introduces integer underflow mitigation in max_addr calculation
+in grub_relocator_alloc_chunk_align() invocation.
+
+It consists of 2 fixes:
+  1. Introduced grub_relocator_alloc_chunk_align_safe() wrapper function to perform
+     sanity check for min/max and size values, and to make safe invocation of
+     grub_relocator_alloc_chunk_align() with validated max_addr value. Replace all
+     invocations such as grub_relocator_alloc_chunk_align(..., min_addr, max_addr - size, size, ...)
+     by grub_relocator_alloc_chunk_align_safe(..., min_addr, max_addr, size, ...).
+  2. Introduced UP_TO_TOP32(s) macro for the cases where max_addr is 32-bit top
+     address (0xffffffff - size + 1) or similar.

+Subject: [PATCH] script: Avoid a use-after-free when redefining a
+ function during execution
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Defining a new function with the same name as a previously defined
+function causes the grub_script and associated resources for the
+previous function to be freed. If the previous function is currently
+executing when a function with the same name is defined, this results
+in use-after-frees when processing subsequent commands in the original
+function.
+
+Instead, reject a new function definition if it has the same name as
+a previously defined function, and that function is currently being
+executed. Although a behavioural change, this should be backwards
+compatible with existing configurations because they can't be
+dependent on the current behaviour without being broken.

+Subject: [PATCH] relocator: Fix grub_relocator_alloc_chunk_align() top
+ memory allocation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Current implementation of grub_relocator_alloc_chunk_align()
+does not allow allocation of the top byte.
+
+Assuming input args are:
+  max_addr = 0xfffff000;
+  size = 0x1000;
+
+And this is valid. But following overflow protection will
+unnecessarily move max_addr one byte down (to 0xffffefff):
+  if (max_addr > ~size)
+    max_addr = ~size;
+
+~size + 1 will fix the situation. In addition, check size
+for non zero to do not zero max_addr.

+Both node->size and node->namelen come from the supplied filesystem,
+which may be user-supplied. We can't trust them for the math unless we
+know they don't overflow. Making sure they go through grub_add() or
+grub_calloc() first will give us that.

+
+It appears to be possible to make a (possibly invalid) lvm PV with
+a metadata size field that overflows our type when adding it to the
+address we've allocated. Even if it doesn't, it may be possible to do so
+with the math using the outcome of that as an operand. Check them both.

+The grub_free() implementation in grub-core/kern/mm.c safely handles

+that the same is true on all host OSes, so we need to handle the same

+Subject: [PATCH] efi: Fix some malformed device path arithmetic errors
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Several places we take the length of a device path and subtract 4 from
+it, without ever checking that it's >= 4. There are also cases where
+this kind of malformation will result in unpredictable iteration,
+including treating the length from one dp node as the type in the next
+node. These are all errors, no matter where the data comes from.
+
+This patch adds a checking macro, GRUB_EFI_DEVICE_PATH_VALID(), which
+can be used in several places, and makes GRUB_EFI_NEXT_DEVICE_PATH()
+return NULL and GRUB_EFI_END_ENTIRE_DEVICE_PATH() evaluate as true when
+the length is too small. Additionally, it makes several places in the
+code check for and return errors in these cases.

+Subject: [PATCH] efi: Fix use-after-free in halt/reboot path
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 92bfc33db984 ("efi: Free malloc regions on exit")
+introduced memory freeing in grub_efi_fini(), which is
+used not only by exit path but by halt/reboot one as well.
+As result of memory freeing, code and data regions used by
+modules, such as halt, reboot, acpi (used by halt) also got
+freed. After return to module code, CPU executes, filled
+by UEFI firmware (tested with edk2), 0xAFAFAFAF pattern as
+a code. Which leads to #UD exception later.

+Proposal here is to continue to free allocated memory for

+==== Patches for maintenance branches
+
+When fixing bugs on a maintenance branch, bugs should be fixed on the
+master branch first. The commit log for such a patch may then contain a
+post-commit note specifying what branches are affected:
+
+----
+package/foo: fix stuff
+
+Signed-off-by: Your Real Name <your@email.address>
+---
+Backport to: 2020.02.x, 2020.05.x
+(2020.08.x not affected as the version was bumped)
+----
+
+Those changes will then be backported by a maintainer to the affected
+branches.
+
+However, some bugs may apply only to a specific release, for example
+because it is using an older version of a package. In that case, patches
+should be based off the maintenance branch, and the patch subject prefix
+must include the maintenance branch name (for example "[PATCH 2020.02.x]").
+This can be done with the +git format-patch+ flag +--subject-prefix+:
+
+---------------------
+$ git format-patch --subject-prefix "PATCH 2020.02.x" \
