The old one was rather confusing. Switch to returning 1/0 for whether
the padding is publicly invalid and then add an output argument which

Add the following cases:
- Maximal padding
- Maximal padding with each possible byte position wrong.
- When the input is not publicly too short to find a MAC, but the
unpadded value is too short. (This tests that
EVP_tls_cbc_remove_padding and EVP_tls_cbc_copy_mac coordinate
correctly. EVP_tls_cbc_remove_padding promises to also consider it
invalid padding if there is no room for a MAC.)

We currently have the situation where the |tool| and |bssl_shim| code
includes scoped_types.h from crypto/test and ssl/test. That's weird and
shouldn't happen. Also, our C++ consumers might quite like to have
access to the scoped types.
Thus this change moves some of the template code to base.h and puts it
all in a |bssl| namespace to prepare for scattering these types into
their respective headers. In order that all the existing test code be
able to access these types, it's all moved into the same namespace.

There's a __pragma expression which allows this. Android builds us Windows with
MinGW for some reason, so we actually do have to tolerate non-MSVC-compatible
Windows compilers. (Clang for Windows is much more sensible than MinGW and
intentionally mimicks MSVC.)
MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a

An overflow can occur in the EVP_EncryptUpdate function. If an attacker is
able to supply very large amounts of input data after a previous call to
EVP_EncryptUpdate with a partial block then a length check can overflow
resulting in a heap corruption.
Following an analysis of all OpenSSL internal usage of the
EVP_EncryptUpdate function all usage is one of two forms.
The first form is like this:
EVP_EncryptInit()
EVP_EncryptUpdate()
i.e. where the EVP_EncryptUpdate() call is known to be the first called
function after an EVP_EncryptInit(), and therefore that specific call
must be safe.
The second form is where the length passed to EVP_EncryptUpdate() can be seen
from the code to be some small value and therefore there is no possibility of
an overflow. [BoringSSL: We also have code that calls EVP_CIPHER functions by
way of the TLS/SSL3 "AEADs". However, there we know the inputs are bounded by
2^16.]
Since all instances are one of these two forms, I believe that there can
be no overflows in internal code due to this problem.
It should be noted that EVP_DecryptUpdate() can call EVP_EncryptUpdate()
in certain code paths. Also EVP_CipherUpdate() is a synonym for
EVP_EncryptUpdate(). Therefore I have checked all instances of these
calls too, and came to the same conclusion, i.e. there are no instances
in internal usage where an overflow could occur.
This could still represent a security issue for end user code that calls
this function directly.

that suppressed warnings on a per-function basis no longer work in

Unfortunately, this requires an ugly hack to continue working in

Updated by davidben to give up on suppressing warnings in crypto/x509 and
crypto/x509v3 as those directories aren't changed much from upstream. In each
of these cases, upstream opted just blindly initialize the variable, so do the
same. Also switch C4265 to level 4, per Microsoft's recommendation and work
around a bug in limits.h that happens to get fixed by Google include order
style.
(limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some
other headers, is included before it. The reason it affected just one file is
we often put the file's header first, which means base.h is pulling in
stddef.h. Relying on this is ugly, but it's no worse than what everything else
is doing and this doesn't seem worth making something as tame as limits.h so
messy to use.)

We can reuse the HMAC_CTX that stores the key. The API is kind of unfortunate
as, in principle, it should be possible to do an allocation-averse HMAC with a
shared key on multiple threads at once (EVP_AEAD_CTX is normally logically
const). At some point it may be worth rethinking those APIs somewhat. But
these "stateful AEADs" are already stateful in their EVP_CIPHER_CTX, so this is
fine.
Each cipher was run individually to minimize the effect of other ciphers doing
their mallocs. (Although the cost of a malloc is presumably going to depend a
lot on the malloc implementation and what's happened before in the process, so
take these numbers with a bucket of salt. They vary widely even with the same
arguments.)
Taking malloc out of seal/open also helps with the malloc tests. DTLS currently
cannot distinguish a malloc failure (should be fatal) from a decryption failure
(not fatal), so the malloc tests get stuck. But this doesn't completely get us
there since tls_cbc.c mallocs. This also assumes EVP_CIPHER_CTX, EVP_MD_CTX,
and HMAC_CTX are all clever about reusing their allocations when reset (which
they are).

This reverts most of commit 271777f5ac. The old
ChaCha20-Poly1305, though being transitioned to the old name, should not change
in behavior. This also avoids adding a special-case to SSL_AEAD_CTX.
Also revert the name change to SSL_CIPHER_is_CHACHA20POLY1305. The one consumer
for that function doesn't need to distinguish the old and new variants, so
avoid unnecessary turbulence.

QUIC has a complex relationship with BoringSSL owing to it living both
in Chromium and the Google-internal repository. In order for it to
handle the ChaCha20-Poly1305 AEAD switch more easily this change gives
the unsuffixed name to the old AEAD, for now.
Once QUIC has moved to the “_old” version the unsuffixed name can be
given to the new version.

The tests in crypto/cipher/test/chacha20_poly1305_deprecated_tests.txt
were adapted to the RFC 7539 AEAD construction by recalculating the tags.
Also a few additional vectors were added. These vectors were verified
against nettle. See
feb7292bf1.

This change reduces unnecessary copying and makes the pre-RFC-7539
nonces 96 bits just like the AES-GCM, AES-CCM, and RFC 7539
ChaCha20-Poly1305 cipher suites. Also, all the symbols related to
the pre-RFC-7539 cipher suites now have "_OLD" appended, in
preparation for adding the RFC 7539 variants.

The new function |CRYPTO_chacha_96_bit_nonce_from_64_bit_nonce| can be
used to adapt code from that uses 64 bit nonces, in a way that is
compatible with the old semantics.

gcm_test.cc needs to access the internal GCM symbols. This is
unfortunate because it means that they have to be marked OPENSSL_EXPORT
just for this.
To compensate, modes.h is removed and its contents copied into
crypto/modes/internal.h.

This removes the confusion about whether |gcm128_context| copies the
key (it didn't) or whether the caller is responsible for keeping the
key alive for the lifetime of the |gcm128_context| (it was).

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.

Some ARM environments don't support |getauxval| or signals and need to
configure the capabilities of the chip at compile time. This change adds
defines that allow them to do so.

To avoid too much #if soup, e_aes.c uses a lot of dummy functions that
just call |abort|. This change makes them all static, which they should
have been all along.
