Even without strict-aliasing, C does not allow casting pointers to types
that don't match their alignment. After this change, UBSan is happy with
our code at default settings but for the negative left shift language
bug.
Note: architectures without unaligned loads do not generate the same
code for memcpy and pointer casts. But even ARMv6 can perform unaligned
loads and stores (ARMv5 couldn't), so we should be okay here.

Currently we only check that the underlying EC_METHODs match, which
avoids the points being in different forms, but not that the points are
on the same curves. (We fixed the APIs early on so off-curve EC_POINTs
cannot be created.)
In particular, this comes up with folks implementating Java's crypto
APIs with ECDH_compute_key. These APIs are both unfortunate and should
not be mimicked, as they allow folks to mismatch the groups on the two
multiple EC_POINTs. Instead, ECDH APIs should take the public value as a
byte string.
Thanks also to Java's poor crypto APIs, we must support custom curves,
which makes this particularly gnarly. This CL makes EC_GROUP_cmp work
with custom curves and adds an additional subtle requirement to
EC_GROUP_set_generator.
Annoyingly, this change is additionally subtle because we now have a
reference cycle to hack around.

replacing the EC_METHOD pointer in EC_POINT with EC_GROUP not
*completely* insane, make them refcounted.
OpenSSL did not do this because their EC_GROUPs are mutable
(EC_GROUP_set_asn1_flag and EC_GROUP_set_point_conversion_form). Ours
are immutable but for the two-function dance around custom curves (more
of OpenSSL's habit of making their objects too complex), which is good
enough to refcount.

Our assembly does not use the GOT to reference symbols, which means
references to visible symbols will often require a TEXTREL. This is
undesirable, so all assembly-referenced symbols should be hidden. CPU
capabilities are the only such symbols defined in C.
These symbols may be hidden by doing at least one of:
1. Build with -fvisibility=hidden
2. __attribute__((visibility("hidden"))) in C.
3. .extern + .hidden in some assembly file referencing the symbol.
We have lots of consumers and can't always rely on (1) happening. We
were doing (3) by way of d216b71f90 and
16e38b2b8f, but missed 32-bit x86 because
it doesn't cause a linker error.
Those two patches are not in upstream. Upstream instead does (3) by way
of x86cpuid.pl and friends, but we have none of these files.
Standardize on doing (2). This avoids accidentally getting TEXTRELs on
some 32-bit x86 build configurations. This also undoes
d216b71f90 and
16e38b2b8f. They are no now longer needed
and reduce the upstream diff.

Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.
Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.
This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.
It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:
- SSL_CTX_sess_set_get_cb is now const-correct.
- X509_get0_signature is now const-correct.
For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.
The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.

Thanks to Lennart Beringer for pointing that that malloc failures could

general so that fallible operations are all performed before mutating
objects. Thus failures should leave objects in a valid state.
Also, |ctx_size| is never zero and a hash with no context is not
sensible, so stop handling that case and simply assert that it doesn't

We have an SDE bot now and can more easily test things. We also enabled
ADX in rsaz-avx2.pl which does not work without x86_64-mont*.pl enabled.
rsa-avx2.pl's ADX code only turns itself off so that the faster ADX code
can be used... but we disable it.
Verified, after reverting the fix, the test vectors we imported combined
with Intel SDE catches CVE-2016-7055, so we do indeed have test
coverage.

This isn't all of our pointer games by far, but for any code which

For code with does care about armv6 (do we care?), it'll need a bit more

Ironically, the one platform where C needs its alignment rules is the
one platform that makes it hard to honor C's alignment rules.

POWER8 has hardware transactional memory, which glibc uses to implement
locks. In some cases, taking a lock begins a transaction, wrapping
arbitrary user code (!) until the lock is released. If the transaction
is aborted, everything rewinds and glibc tries again with some other
implementation.
The kernel will abort the transaction in a variety of cases. Notably, on
a syscall, the transaction aborts and the syscall *does not happen*.
https://www.kernel.org/doc/Documentation/powerpc/transactional_memory.txt
Yet, for some reason, although the relevant change does appear to be in
the kernel, the transaction is being rewound with getrandom happening
anyway. This does not work very well.
Instead, only guard the DRBG access with the lock, not CRYPTO_sysrand.
This lock is only used to protect the DRBG from the destructor that
zeros everything.

It's less stringtastic than the old code, however the parser isn't as

consistent across platforms. At least for ppc64le, that does not appear

The only place it is used is EC_KEY_{dup,copy} and no one calls that
function on an EC_KEY with ex_data. This aligns with functions like
RSAPublicKey_dup which do not copy ex_data. The logic is also somewhat
subtle in the face of malloc errors (upstream's PR 3323).
In fact, we'd even changed the function pointer signature from upstream,
so BoringSSL-only code is needed to pass this pointer in anyway. (I
haven't switched it to CRYPTO_EX_unused because there are some callers
which pass in an implementation anyway.)
Note, in upstream, the dup hook is also used for SSL_SESSIONs when those
are duplicated (for TLS 1.2 ticket renewal or TLS 1.3 resumption). Our
interpretation is that callers should treat those SSL_SESSIONs
equivalently to newly-established ones. This avoids every consumer
providing a dup hook and simplifies the interface.
(I've gone ahead and removed the TODO(fork). I don't think we'll be able
to change this API. Maybe introduce a new one, but it may not be worth
it? Then again, this API is atrocious... I've never seen anyone use argl

comparing <= 0, but the EVP_AEAD API did not.
I've done the test in a separate file on the assumption that aead_test
will become GTest shortly, at which point it will be easy to stick extra
tests into the same file as the FileTest ones.
Thanks to Daniel Bleichenbacher and Thanh Bui of Project Wycheproof for
the report.

This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:
- It returns void and expects failures to use the GTest EXPECT_* and
ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
work to convert, but ultimately less work to add new tests. I think
it's also valuable for our FileTest and normal test patterns to align
as much as possible. The line number is emitted via SCOPED_TRACE.
- I've intentionally omitted the Error attribute handling, since that
doesn't work very well with the new callback. This means evp_test.cc
will take a little more work to convert, but this is again to keep our
two test patterns aligned.
- The callback takes a std::function rather than a C-style void pointer.
This means we can go nuts with lambdas. It also places the path first
so clang-format doesn't go nuts.

This change causes FIPS mode to use RDRAND in preference to the kernel's
entropy pool. This prevents issues where the ioctl that we have to do
when getrandom isn't supported transiently reports that the pool is
“empty” and causes us to block.
