896332581e Appease UBSan on pointer alignment.
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.

929f842810 Remove custom memcpy and memset from poly1305_vec.
This avoids upsetting the C compiler. UBSan is offended by the alignment
violations in those functions. The business with offset is also
undefined behavior (pointer arithmetic is supposed to stay within a
single object).

There is a small performance cost, however:

55761e6802 Use a higher iteration limit for RSA key generation at e = 3.
Generating a 2048-bit RSA key with e = 3 (don't do this), the failure
rate at 5*bits iterations appears to be around 7 failures in 1000 tries.
Bump the limit up to 32*bits. This should give a failure rate of around
2 failures in 10^14 tries.

(The FIPS 186-4 algorithm is meant for saner values of e, like 65537. e
= 3 implies a restrictive GCD requirement: the primes must both be 2 mod
3.)

431e767c23 curve25519: adhere to preconditions of fe_*.
Previously, the ed25519 and SPAKE implementations called field element
operations in ways that did not satisfy the preconditions about ranges
of limbs. Furthermore, replacing signed field arithmetic with unsigned field
arithmetic with similar specifications caused tests to fail.  This commit
addresses this in three steps:

(1) Split fe into fe and fe_loose, tracking the bounds
(2) Insert carry operations before uses of fe_add/fe_sub/fe_neg whose
input is already within only the loose bounds
(3) Assert that each field element is within the appropriate bounds at
the beginning and end of every field operation.

This bug does not affect BoringSSL as we do not enable the ADX code.
Note the test vector had to be tweaked to take things in and out of
Montgomery form. (There may be something to be said for test vectors for
just BN_mod_mul_montgomery, though we'd need separate 64-bit and 32-bit
ones because R can be different.)

696c13bd6a Clear bottom three bits of password scalar in SPAKE2.
Due to a copy-paste error, the call to |left_shift_3| is missing after
reducing the password scalar in SPAKE2. This means that three bits of
the password leak in Alice's message. (Two in Bob's message as the point
N happens to have order 4l, not 8l.)

The “correct” fix is to put in the missing call to |left_shift_3|, but
that would be a breaking change. In order to fix this in a unilateral
way, we add points of small order to the masking point to bring it into
prime-order subgroup.

65d414434aeecd5aa86a46adbfbcb59b4344503a.)

I do not believe this is actually reachable in BoringSSL, even in the
face of malloc errors. The only field which sets ASN1_TFLG_COMBINE is in
X509_ATTRIBUTE. That field's value is X509_ATTRIBUTE_SET which cannot
fail to initialize. (It is a CHOICE whose initialization consists of
setting the selector to -1 and calling the type's callback which is
unset for this type.)

cb16f17b36 Check EC_POINT/EC_GROUP compatibility more accurately.
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.

and primes just a hair larger than a u8 length prefix alows.

51073ce055 Refcount EC_GROUP.
I really need to resurrect the CL to make them entirely static
(https://crbug.com/boringssl/20), but, in the meantime, to make
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.

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.

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.

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.

246e27d807 Switch the buggy RSA parser off by default.
I'll fully remove this once Chrome 62 hits stable, in case any bug
reports come in for Chrome 61. Meanwhile switch the default to off so
that other consumers pick up the behavior. (Should have done this sooner
and forgot.)

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.

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.

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.

68a0b1b112 Remove RFC 5114 groups.
These groups are terrible, we got the function wrong (unused ENGINE
parameter does not match upstream), and the functions are unused. Unwind
them. This change doesn't unwind the X9.42 Diffie-Hellman machinery, so
the checks are still present and tested.

(We can probably get rid of the X9.42 machinery too, but it is reachable
from DSA_dup_DH.  That's only used by wpa_supplicant and, if that code
ever ran, it'd be ignored because we don't support DHE in TLS. I've left
it alone for the time being.)

488ca0eace Enable ADX in x86_64-mont*.pl.
This is a reland of https://boringssl-review.googlesource.com/18965
which was reverted due to Windows toolchain problems that have since
been fixed.

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. Also verified on the Windows version of Intel SDE.

Thanks to Alexey Ivanov for pointing out the discrepancy.

This reverts commit 83d1a3d3c8.

Reason for revert: Our Windows setup can't handle these instructions.
Will investigate tomorrow, possibly by turning ADX off on Windows.

2916430ddb Test that nullptr has the obvious memory representation.
Apparently C does not promise this, only that casting zero to a pointer
gives NULL. No compiler will be insane enough to violate this, but it's
an easy assumption to document.
