fed560ff2a Clear no-op BN_MASK2 masks.
This is an OpenSSL thing to support platforms where BN_ULONG is not
actually the size it claims to be. We define BN_ULONG to uint32_t and
uint64_t which are guaranteed by C to implement arithemetic modulo 2^32
and 2^64, respectively. Thus there is no need for any of this.

cba7987978 Revert "Use uint128_t and __asm__ in clang-cl."
This reverts commit f6942f0d22.

Reason for revert: This doesn't actually work in clang-cl. I
forgot we didn't have the clang-cl try bots enabled! :-( I
believe __asm__ is still okay, but I'll try it by hand
tomorrow.

Original change's description:
> Use uint128_t and __asm__ in clang-cl.

> clang-cl does not define __GNUC__ but is still a functioning clang. We
> should be able to use our uint128_t and __asm__ code in it on Windows.

38636aba74 Hide CPU capability symbols in C.
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.

40e94701dc Always process handshake records in full.
This removes the last place where non-app-data hooks leave anything
uncomsumed in rrec. (There is still a place where non-app-data hooks see
a non-empty rrec an entrance. read_app_data calls into read_handshake.
That'll be fixed in a later patch in this series.)

This should not change behavior, though some error codes may change due
to some processing happening in a slightly different order.

Since we do this in a few places, this adds a BUF_MEM_append with tests.

63a0797ff2 Remove now unnecessary _POSIX_C_SOURCE bits to work around macOS bug.
crypto/bio/bio_test.cc - I'm not sure where this was added for, but none
   of the functions used there appear to have feature macros documented.
crypto/bio/printf.c - -std=c99 provides (v)snprintf.
crypto/lhash/lhash_test.cc - we no longer call rand_r.
crypto/mem.c - we no longer call strdup and -std=c99 provides (v)snprintf.

Apple messed up their headers and, if _POSIX_C_SOURCE is defined but
_DARWIN_C_SOURCE isn't, pthread.h no longer defines mach_port_t. They
then shipped a version of libc++ headers that is missing this fix, so
the build breaks:
bcc92d75df

If one uses XCode, they've hacked their pthread.h to provide mach_port_t
if defined(__cplusplus), but the standalone tools appear to be old and
missing this.

We can work around this by also defining _DARWIN_C_SOURCE in C++ files
that need _POSIX_C_SOURCE, but it appears none of these files actually
need it.

81f030b106 Switch OPENSSL_VERSION_NUMBER to 1.1.0.
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.

c03c218190 Fix some issues with name constraints test certs.
First, I spelled the wildcard name constraint in many_constraints.pem
wrong. It's .test, not *.test for name constraints. (This doesn't matter
for some_names*.pem, but it does to avoid a false negative in
many_names3.pem.)

Second, the CN of certs should be a host, not "Leaf". OpenSSL 1.1.0
checks "host-like" CNs against name constraints too and "Leaf" is
host-like.

I've also made the generator deterministic and checked it in, as PEM
blobs are not reviewable.

6b35262272 Maintain EVP_MD_CTX invariants.
Thanks to Lennart Beringer for pointing that that malloc failures could
lead to invalid EVP_MD_CTX states. This change cleans up the code in
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
occur.

82dfea8d9e Bound everything parsed by the legacy ASN.1 stack.
crypto/asn1 routinely switches between int and long without overflow
checks. Fortunately, it funnels everything into a common entrypoint, so
we can uniformly bound all inputs to something which comfortably fits in
an int.

a16e86ced5 Don't depend on 16-byte alignment from malloc.
Windows provides _aligned_malloc, so we could provide an
|OPENSSL_aligned_malloc| in the future. However, since we're still
trying to get the zeroisation change landed everywhere, a self-contained
change seems easier until that has settled down.

b86be3617d Guard against DoS in name constraints handling.
This guards against the name constraints check consuming large amounts
of CPU time when certificates in the presented chain contain an
excessive number of names (specifically subject email names or subject
alternative DNS names) and/or name constraints.

Name constraints checking compares the names presented in a certificate
against the name constraints included in a certificate higher up in the
chain using two nested for loops.

Move the name constraints check so that it happens after signature
verification so peers cannot exploit this using a chain with invalid
signatures. Also impose a hard limit on the number of name constraints
check loop iterations to further mitigate the issue.

Thanks to NCC for finding this issue.

3c995f30e7 Fix overflow in c2i_ASN1_BIT_STRING.
c2i_ASN1_BIT_STRING takes length as a long but uses it as an int. Check bounds
before doing so. Previously, excessively large inputs to the function could
write a single byte outside the target buffer. (This is unreachable as
asn1_ex_c2i already uses int for the length.)

Thanks to NCC for finding this issue.

c0e15d1d9d Zero memory in |OPENSSL_free|.
Allocations by |OPENSSL_malloc| are prefixed with their length.
|OPENSSL_free| zeros the allocation before calling free(), eliminating
the need for a separate call to |OPENSSL_cleanse| for sensitive data.

This change will be followed up by the cleanup in
https://boringssl-review.googlesource.com/c/boringssl/+/19824.

28d6979b7e Print errors better in FileTestGTest.
Rather than clear them, even on failure, detect if an individual test
failed and dump the error queue there. We already do this at the GTest
level in ErrorTestEventListener, but that is too coarse-grained for the
file tests.

24e36099ce Teach evp_test to verify by round-tripping.
We have no tests for encryption right now, and evp_tests.txt needs to
force RSA-PSS to have salt length 0, even though other salt values are
more common. This also lets us test the salt length -2 silliness.

8459d06599 Properly size_t EVP_PKEY_CTX_set0_rsa_oaep_label.
We do not expose EVP_PKEY_CTX_ctrl, so we can freely change the
semantics of EVP_PKEY_CTRL_RSA_OAEP_LABEL. That means we can pass in an
actual size_t rather than an int.

Not that anyone is actually going to exceed an INT_MAX-length RSA-OAEP
label.
