It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.
Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.
CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.
Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.

arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.
It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

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.

OpenSSL has traditionally done reference counting with |int|s and the
|CRYPTO_add| function. Unless a special callback is installed (rare),
this is implemented by doing the reference count operations under a
lock.
This change adds infrastructure for handling reference counts and uses
atomic operations when C11 support is available.

This adds a file-based test framework to crypto/test. It knows how to
parse formats similar to either upstream's evp_test and our aead_test.
hmac_test has been converted to that with tests from upstream's
evp_test. Upstream tests it against the deprecated EVP_PKEY_HMAC API,
which will be tested by running evp_test against the same input file, to
avoid having to duplicate the test vectors. hmac_test runs those same
inputs against the supported HMAC_CTX APIs.

The interface for this is very similar to upstream, but the code is
quite different.
Support for “resuming” (i.e. calling |CMAC_Final| and then computing the
CMAC for an extension of the message) has been dropped. Also, calling
|CMAC_Init| with magic argument to reset it has been replaced with
|CMAC_Reset|.
Lastly, a one-shot function has been added because it can save an
allocation and that's what most callers actually appear to want to do.

Previously I've been using the Linaro toolchains and just building
static binaries. However, the Linaro toolchains have a broken
pthread_rwlock_wrlock—it does nothing and then unlocking corrupts the
lock.
Building with the Android NDK avoids this.
These build instructions depend on
https://github.com/taka-no-me/android-cmake which people will need to
clone into util/ if they want to use the Android NDK.

This is as partial import of upstream's
9b05cbc33e7895ed033b1119e300782d9e0cf23c. It includes the perlasm changes, but
not the CPU feature detection bits as we do those differently. This is largely
so we don't diverge from upstream, but it'll help with iOS assembly in the
future.
sha512-armv8.pl is modified slightly from upstream to switch from conditioning
on the output file to conditioning on an extra argument. This makes our
previous change from upstream (removing the 'open STDOUT' line) more explicit.

Historically, OpenSSL has used callbacks for anything thread related,
but we don't actually have that many threading libraries to worry about:
just pthreads and Windows (I hope).
That suggests that it's quite reasonable to handle threading ourselves,
and eliminate the need for users to remember to install the thread
callbacks.
The first user of this would be ERR, which currently simulates
thread-local storage using a lock around a hash table keyed by the TID.
(Although I suspect that change will need some CMake work in order that
libpthread is automatically included with libcrypto when linking tests
etc, but not on Windows and without lots of ifs.)

Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

Android didn't have getauxval until Jelly Bean (4.1). This means that
BoringSSL running on older Androids won't be able to detect NEON
support. (This is moot for Chromium because Chromium calls
android_getCpuFeatures and sets the NEON flag itself, but other users of
BoringSSL on Android probably won't do that.)
This change mirrors a little of what upstream does and tries running a
NEON instruction with a handler for SIGILL installed.

This is an initial cut at aarch64 support. I have only qemu to test it

This also affects 32-bit ARM in that aarch64 chips can run 32-bit code

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

SHA-1 and SHA-256 don't work like this however because they've never

Compilers have a bad habit of removing "superfluous" memset calls that
are trying to zero memory. For example, when memset()ing a buffer and
then free()ing it, the compiler might decide that the memset is
unobservable and thus can be removed.
Previously we tried to stop this by a) implementing memset in assembly
on x86 and b) putting the function in its own file for other platforms.
This change removes those tricks in favour of using asm directives to
scare the compiler away. As best as our compiler folks can tell, this is
sufficient and will continue to be so.

Apart from the obvious little issues, this also works around a
(seeming) libtool/linker:
a.c defines a symbol:
int kFoo;
b.c uses it:
extern int kFoo;
int f() {
return kFoo;
}
compile them:
$ gcc -c a.c
$ gcc -c b.c
and create a dummy main in order to run it, main.c:
int f();
int main() {
return f();
}
this works as expected:
$ gcc main.c a.o b.o
but, if we make an archive:
$ ar q lib.a a.o b.o
and use that:
$ gcc main.c lib.a
Undefined symbols for architecture x86_64
"_kFoo", referenced from:
_f in lib.a(b.o)
(It doesn't matter what order the .o files are put into the .a)
Linux and Windows don't seem to have this problem.
nm on a.o shows that the symbol is of type "C", which is a "common symbol"[1].
Basically the linker will merge multiple common symbol definitions together.
If ones makes a.c read:
int kFoo = 0;
Then one gets a type "D" symbol - a "data section symbol" and everything works
just fine.
This might actually be a libtool bug instead of an ld bug: Looking at `xxd
lib.a | less`, the __.SYMDEF SORTED index at the beginning of the archive
doesn't contain an entry for kFoo unless initialised.
