Update all existing Google copyright lines to 'The BoringSSL Authors'

All other existing copyright lines are left unmodified. Going forward,
our preference will be that new contributions to BoringSSL use 'The

cpu.h contains almost entirely private symbols, which aren't reliably
usable outside the library because they lack OPENSSL_EXPORT. (And can't
have OPENSSL_EXPORT. The linker wants references to exported symbols to
go through the GOT, and our assembly doesn't do that.) In preparation
for unexporting them, move the few public APIs to crypto.h. They seem
similar in spirit to functions like CRYPTO_has_asm.
Update-Note: As part of this, I conditioned cpu-arm-linux.c on
OPENSSL_LINUX, so that the header files can have accurate conditions.
This means unrecognized ARM platforms that do not set
OPENSSL_STATIC_ARMCAP will fail to build, where previously we defaulted
to the Linux mechanisms. This matches cpu-aarch64-linux.c, which is
already gated on OPENSSL_LINUX. (And the file is quite Linux-specific.
Even if a non-Linux ELF target used getauxval for ARM capabilities, it's
unlikely that our hardcoded constants and /proc behavior applies
anyway.)

This imports the changes to sha512-armv8.pl from
upstream's af0fcf7b4668218b24d9250b95e0b96939ccb4d1.
Tweaks needed:
- Add an explicit .text because we put .LK$BITS in .rodata for XOM
- .LK$bits and code are in separate sections, so use adrp/add instead of
plain adr
- Where glibc needs feature flags to *enable* pthread_rwlock, Apple
interprets _XOPEN_SOURCE as a request to *disable* Apple extensions.
Tighten the condition on the _XOPEN_SOURCE check.
Added support for macOS and Linux, tested manually on an ARM Mac and a
VM, respectively. Fuchsia and Windows do not currently have APIs to
expose this bit, so I've left in TODOs. Benchmarks from an Apple M1 Max:

In terms of build coverage, for now, we'll have build coverage
everywhere and test coverage on Chromium, which runs this code on macOS
CI. We should request a macOS ARM64 bot for our standalone CI. Longer
term, we need a QEMU-based builder to test various features. QEMU seems
to have pretty good coverage of all this, which will at least give us
Linux.
I haven't added an OPENSSL_STATIC_ARMCAP_SHA512 for now. Instead, we
just look at the standard __ARM_FEATURE_SHA512 define. Strangely, the
corresponding -march tag is not sha512. Neither GCC and nor Clang have
-march=armv8-a+sha512. Instead, -march=armv8-a+sha3 implies both
__ARM_FEATURE_SHA3 and __ARM_FEATURE_SHA512! Yet everything else seems
to describe the SHA512 extension as separate from SHA3.

Update-Note: Consumers with a different build setup may need to
limit -D_XOPEN_SOURCE=700 to Linux or non-Apple platforms. Otherwise,
<sys/types.h> won't define some typedef needed by <sys/sysctl.h>. If you
see a build error about u_char, etc., being undefined in some system

When a feature is enabled statically in the build config, the compiler
defines __ARM_NEON and also considers itself free to emit NEON code.
In this case, there is no need to check for NEON support at runtime
since the binary will not work without NEON anyway. Moving the check to
compile time lets us drop unused code.
Chrome has required NEON on Android for nearly five years now. However,
historically there was a bad CPU which broke on some NEON code, but not
others. See https://crbug.com/341598 and https://crbug.com/606629. We
worked around that CPU by parsing /proc/cpuinfo and intentionally
dropping the optimization. This is not a stable situation, however, as
we're hoping the compiler is not good enough at emitting NEON to trigger
this bug.
Since then, the number of affected devices has dropped, and Chrome has
raised the minimum Android requirement to L. The Net.HasBrokenNEON
metric from Chrome is now well in the noise.
This CL stops short of removing the workaround altogether because some
consumers of Cronet are unsure whether they needed this workaround.
Those consumers also build without __ARM_NEON, so gating on that works
out. We'll decide what to do with it pending metrics from them.
Update-Note: Builds with __ARM_NEON (-mfpu=neon) will now drop about
30KiB of dead code, but no longer work (if they even did before) on a
particular buggy CPU. Builds without __ARM_NEON are not affected.

UNIX, CMake does not pass NDEBUG to NASM. This is giving gRPC some
difficulties in updating BoringSSL, so switch it to an opt-in

Update-Note: If you were copying NDEBUG over to assembly files, that's

C and C++ handle inline functions differently. In C++, an inline function is
defined in just the header file, potentially emitted in multiple compilation
units (in cases the compiler did not inline), but each copy must be identical
to satsify ODR. In C, a non-static inline must be manually emitted in exactly
one compilation unit with a separate extern inline declaration.
In both languages, exported inline functions referencing file-local symbols are
problematic. C forbids this altogether (though GCC and Clang seem not to
enforce it). It works in C++, but ODR requires the definitions be identical,
including all names in the definitions resolving to the "same entity". In
practice, this is unlikely to be a problem, but an inline function that returns
a pointer to a file-local symbol could compile oddly.
Historically, we used static inline in headers. However, to satisfy ODR, use
plain inline in C++, to allow inline consumer functions to call our header
functions. Plain inline would also work better with C99 inline, but that is not
used much in practice, extern inline is tedious, and there are conflicts with
the old gnu89 model: https://stackoverflow.com/questions/216510/extern-inline
For dual C/C++ code, use a macro to dispatch between these. For C++-only
code, stop using static inline and just use plain inline.
Update-Note: If you see weird C++ compile or link failures in header
functions, this change is probably to blame. Though this change
doesn't affect C and non-static inline is extremely common in C++,
so I would expect this to be fine.

(Thanks to Sam Panzer for the patch.)
At least some linkers will drop constructor functions if no symbols from
that translation unit are used elsewhere in the program. On POWER, since
the cached capability value isn't a global in crypto.o (like other
platforms), the constructor function is getting discarded.
The C++11 spec says (3.6.2, paragraph 4):
It is implementation-defined whether the dynamic initialization of a
non-local variable with static storage duration is done before the
first statement of main. If the initialization is deferred to some
point in time after the first statement of main, it shall occur
before the first odr-use (3.2) of any function or variable defined
in the same translation unit as the variable to be initialized.
Compilers appear to interpret that to mean they are allowed to drop
(i.e. indefinitely defer) constructors that occur in translation units
that are never used, so they can avoid initializing some part of a
library if it's dropped on the floor.
This change makes the hardware capability value for POWER a global in
crypto.c, which should prevent the constructor function from being
ignored.

This removes the thread-unsafe SIGILL-based detection and the
multi-consumer-hostile CRYPTO_set_NEON_capable API. (Changing
OPENSSL_armcap_P after initialization is likely to cause problems.)
The right way to detect ARM features on Linux is getauxval. On aarch64,
we should be able to rely on this, so use it straight. Split this out
into its own file. The #ifdefs in the old cpu-arm.c meant it shared all
but no code with its arm counterpart anyway.
Unfortunately, various versions of Android have different missing APIs, so, on
arm, we need a series of workarounds. Previously, we used a SIGILL fallback
based on OpenSSL's logic, but this is inherently not thread-safe. (SIGILL also
does not tell us if the OS knows how to save and restore NEON state.) Instead,
base the behavior on Android NDK's cpu-features library, what Chromium
currently uses with CRYPTO_set_NEON_capable:
- Android before API level 20 does not provide getauxval. Where missing,
we can read from /proc/self/auxv.
- On some versions of Android, /proc/self/auxv is also not readable, so
use /proc/cpuinfo's Features line.
- Linux only advertises optional features in /proc/cpuinfo. ARMv8 makes NEON
mandatory, so /proc/cpuinfo can't be used without additional effort.
Finally, we must blacklist a particular chip because the NEON unit is broken
(https://crbug.com/341598).
Unfortunately, this means CRYPTO_library_init now depends on /proc being
available, which will require some care with Chromium's sandbox. The
simplest solution is to just call CRYPTO_library_init before entering
the sandbox.
It's worth noting that Chromium's current EnsureOpenSSLInit function already
depends on /proc/cpuinfo to detect the broken CPU, by way of base::CPU.
android_getCpuFeatures also interally depends on it. We were already relying on
both of those being stateful and primed prior to entering the sandbox.

Rather, take a leaf out of Chromium's book and use MSVC's __cpuid and
_xgetbv built-in, with an inline assembly emulated version for other
compilers.
This preserves the behavior of the original assembly with the following
differences:
- CPUs without cpuid aren't support. Chromium's base/cpu.cc doesn't
check, and SSE2 support is part of our baseline; the perlasm code
is always built with OPENSSL_IA32_SSE2.
- The clear_xmm block in cpu-x86-asm.pl is removed. This was used to
clear some XMM-using features if OSXSAVE was set but XCR0 reports the
OS doesn't use XSAVE to store SSE state. This wasn't present in the
x86_64 and seems wrong. Section 13.5.2 of the Intel manual, volume 1,
explicitly says SSE may still be used in this case; the OS may save
that state in FXSAVE instead. A side discussion on upstream's RT#2633
agrees.
- The old code ran some AMD CPUs through the "intel" codepath and some
went straight to "generic" after duplicating some, but not all, logic.
The AMD copy didn't clear some reserved bits and didn't query CPUID 7
for AVX2 support. This is moot since AMD CPUs today don't support
AVX2, but it seems they're expected to in the future?
- Setting bit 10 is dropped. This doesn't appear to be queried anywhere,
was 32-bit only, and seems a remnant of upstream's
14e21f863a3e3278bb8660ea9844e92e52e1f2f7.

RC4_CHAR is a bit in the x86(-64) CPUID information that switches the
RC4 asm code from using an array of 256 uint32_t's to 256 uint8_t's. It
was originally written for the P4, where the uint8_t style was faster.
(On modern chips, setting RC4_CHAR took RC4-MD5 from 458 to 304 MB/s.
Although I wonder whether, on a server with many connections, using less
cache wouldn't be better.)
However, I'm not too worried about a slowdown of RC4 on P4 systems these
days (the last new P4 chip was released nine years ago) and I want the
code to be simplier.
Also, RC4_CHAR was set when the CPUID family was 15, but Intel actually
lists 15 as a special code meaning "also check the extended family
bits", which the asm didn't do.
The RC4_CHAR support remains in the RC4 asm code to avoid drift with
upstream.

This is an initial cut at aarch64 support. I have only qemu to test it
however—hopefully hardware will be coming soon.
This also affects 32-bit ARM in that aarch64 chips can run 32-bit code
and we would like to be able to take advantage of the crypto operations
even in 32-bit mode. AES and GHASH should Just Work in this case: the
-armx.pl files can be built for either 32- or 64-bit mode based on the
flavour argument given to the Perl script.
SHA-1 and SHA-256 don't work like this however because they've never
support for multiple implementations, thus BoringSSL built for 32-bit
won't use the SHA instructions on an aarch64 chip.
No dedicated ChaCha20 or Poly1305 support yet.

Add some missing headers and ensure each header has a short description. doc.go
gets confused at declarations that break before the first (, so avoid doing
that. Also skip a/an/deprecated: in markupFirstWord and process pipe words in
the table of contents.

Otherwise, in C, it becomes a K&R function declaration which doesn't actually
type-check the number of arguments.

Some phones have a buggy NEON unit and the Poly1305 NEON code fails on
them, even though other NEON code appears to work fine.
This change:
1) Fixes a bug where NEON was assumed even when the code wasn't compiled
in NEON mode.
2) Adds a second NEON control bit that can be disabled in order to run
NEON code, but not the Poly1305 NEON code.

This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.
On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h
In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.
In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.
This doesn't work on Windows.
This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
