aacb72c1b7 Move ec/ and ecdsa/ into fipsmodule/
The names in the P-224 code collided with the P-256 code and thus many
of the functions and constants in the P-224 code have been prefixed.

7784104dd8 Move much of rand/ into the FIPS module.
Support for platforms that we don't support FIPS on doesn't need to be
in the module. Also, functions for dealing with whether fork-unsafe
buffering is enabled are left out because they aren't implementing any
cryptography and they use global r/w state, making their inclusion
painful.

0648129566 Move modes/ into the FIPS module
The changes to delocate.go are needed because modes/ does things like
return the address of a module function. Both of these need to be
changed from referencing the GOT to using local symbols.

Rather than testing whether |ghash| is |gcm_ghash_avx|, we can just keep
that information in a flag.

The test for |aesni_ctr32_encrypt_blocks| is more problematic, but I
believe that it's superfluous and can be dropped: if you passed in a
stream function that was semantically different from
|aesni_ctr32_encrypt_blocks| you would already have a bug because
|CRYPTO_gcm128_[en|de]crypt_ctr32| will handle a block at the end
themselves, and assume a big-endian, 32-bit counter anyway.

A follow-up change will add a CRYPTO_BUFFER variant. This makes the
naming match the header and doesn't require including x509.h. (Though
like ssl.h and pkcs8.h, some of the functions are implemented with code
that depends on crypto/x509.)

aff72a3805 Add the start of standalone iOS build support.
The built-in CMake support seems to basically work, though it believes
you want to build a fat binary which doesn't work with how we build
perlasm. (We'd need to stop conditioning on CMAKE_SYSTEM_PROCESSOR at
all, wrap all the generated assembly files in ifdefs, and convince the
build to emit more than one. Probably not worth bothering for now.)

We still, of course, need to actually test the assembly on iOS before
this can be shipped anywhere.

966284337d Do a cursory conversion of a few tests to GTest.
For now, this is the laziest conversion possible. The intent is to just
get the build setup ready so that we can get everything working in our
consumers. The intended end state is:

- The standalone build produces three test targets, one per library:
  {crypto,ssl,decrepit}_tests.

- Each FOO_test is made up of:
    FOO/**/*_test.cc
    crypto/test/gtest_main.cc
    test_support

- generate_build_files.py emits variables crypto_test_sources and
  ssl_test_sources. These variables are populated with FindCFiles,
  looking for *_test.cc.

- The consuming file assembles those variables into the two test targets
  (plus decrepit) from there. This avoids having generate_build_files.py
  emit actual build rules.

- Our standalone builders, Chromium, and Android just run the top-level
  test targets using whatever GTest-based reporting story they have.

In transition, we start by converting one of two tests in each library
to populate the three test targets. Those are added to all_tests.json
and all_tests.go hacked to handle them transparently. This keeps our
standalone builder working.

generate_build_files.py, to start with, populates the new source lists
manually and subtracts them out of the old machinery. We emit both for
the time being. When this change rolls in, we'll write all the build
glue needed to build the GTest-based tests and add it to consumers'
continuous builders.

Next, we'll subsume a file-based test and get the consumers working with
that. (I.e. make sure the GTest targets can depend on a data file.)

Once that's all done, we'll be sure all this will work. At that point,
we start subsuming the remaining tests into the GTest targets and,
asynchronously, rewriting tests to use GTest properly rather than
cursory conversion here.

When all non-GTest tests are gone, the old generate_build_files.py hooks
will be removed, consumers updated to not depend on them, and standalone
builders converted to not rely on all_tests.go, which can then be
removed. (Unless bits end up being needed as a malloc test driver. I'm
thinking we'll want to do something with --gtest_filter.)

As part of this CL, I've bumped the CMake requirements (for
target_include_directories) and added a few suppressions for warnings
that GTest doesn't pass.

Upstream has now unified on the first form after making a number of

and update CMakeLists.txt and generate_build_files.py per the new
convention.

This imports various commits like this one:

There was only one function that required BoringSSL to know how to read
directories. Unfortunately, it does have some callers and it's not immediately
obvious whether the code is unreachable. Rather than worry about that, just
toss it all into decrepit.

In doing so, do away with the Windows and PNaCl codepaths. Only implement
OPENSSL_DIR_CTX on Linux.

However, it does not interoperate, due to the replacement of SHAKE-128
with AES-CTR (for polynomial generation) and the replacement of SHA-3

054e151b16 Rewrite ARM feature detection.
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.

301afaf223 Add a run_tests target to run all tests.
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

7315251d4e Replace cpuid assembly with C code.
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.

d7c5dfb233 Add native support for onces and thread-local storage.
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.)

29b186736c Precompute sorted array for error strings.
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.

507c1eec51 Honor the standard BUILD_SHARED_LIBS cmake variable.
The variable switches the default type for add_library from STATIC to SHARED.
We can condition additional stuff on that for convenience. (tabtest still
doesn't build.)

BoringSSL as any kind of stable system shared library is still very much
unsupported, but this is probably handy for making sure we don't forget all
those pesky OPENSSL_EXPORTs.

3e6526575a aarch64 support.
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.

bc786a9569 Build with yasm on Win64 as well.
Chromium's doesn't have built-in support for ml64.exe. Seems easier to
just build consistently with Yasm on both Win32 and Win64. (This will
require an equivalent change in Chromium's build, but keep upstream
and downstream builds consistent.)

Also don't set CMAKE_ASM_NASM_COMPILER explicitly; cmake's default
ASM_NASM behavior will search for both nasm or yasm in %PATH%. Leave
it unset so it can be overwritten on the command-line to point to
a particular yasm. Update BUILDING accordingly.

Verified the tests still pass.

03a739d8d2 Build Win32 with Yasm rather than MASM.
Although x86masm.pl exists, upstream's documentation suggest only x86nasm.pl is
supported. Yasm seems to handle it fine with a small change.

3e700bb3e8 Get MASM output working on Win32.
We were building the NASM flavor with MASM which is why it didn't work. Get the
MASM output working: cpuid and cmove are not available in MASM unless the file
declares .686. Also work around MASM rejecting a very long line in SHA-256.

The follow-up change will get the NASM flavor working. We should probably use
that one as it's documented as supported upstream. But let's make this one
functional too.

a70c75cfc0 Add a CRYPTO_library_init and static-initializer-less build option.
Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.

Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.

ad1907fe73 Use asm directives to protect OPENSSL_cleanse.
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.

30eda1d2b8 Include some build fixes for OS X.
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.
