BoringSSL depends on the platform's locking APIs to make internal global
state thread-safe, including the PRNG. On some single-threaded embedded
platforms, locking APIs may not exist, so this dependency may be disabled
with a build flag.
Doing so means the consumer promises the library will never be used in any
multi-threaded address space. It causes BoringSSL to be globally thread-unsafe.
Setting it inappropriately will subtly and unpredictably corrupt memory and
leak secret keys.
Unfortunately, folks sometimes misinterpreted OPENSSL_NO_THREADS as skipping an
internal thread pool or disabling an optionally extra-thread-safe mode. This is
not and has never been the case. Rename it to
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED to clarify what
this option does.
Update-Note: As a first step, this CL makes both OPENSSL_NO_THREADS and
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED work. A later CL
will remove the old name, so migrate callers after or at the same time as
picking up this CL.

Providing a size hint to the allocator is substantially faster,
especially as we already know/need the size for OPENSSL_cleanse.
We provide a weak symbol that falls back to free when a malloc with
sdallocx is not statically linked with BoringSSL.
Alternatives considered:
* Use dlsym(): This is prone to fail on statically linked binaries
without symbols. Additionally, the extra indirection adds call
overhead above and beyond the linker resolved technique we're using.
* Use CMake rules to identify whether sdallocx is available: Once the
library is built, we may link against a variety of malloc
implementations (not all of which may have sdallocx), so we need to
have a fallback when the symbol is unavailable.

MSan works by instrumenting memory accesses in the compiler. Accesses from
uninstrumented code, such as assembly, are invisible to it. MSan will
incorrectly report reads from assembly-initialized memory as uninitialized.
To avoid confusing downstream consumers with false positives, catch this at
compile-time with a more useful error.
Update-Note: BoringSSL with MSan and assembly doesn't work, but now rather than
crashing at runtime, it will fail to build altogether. It's possible someone
was building BoringSSL with MSan and either not running it at all or just not
exercising the codepaths that break.

The DSA code is deprecated and will, hopefully, be removed in the future.
Nonetheless, this is easy enough to fix. It's the analog of the work we'd
already done for ECDSA.
- Document more clearly that we don't care about the DSA code.
- Use the existing constant-time modular addition function rather than
the ad-hoc code.
- Reduce the digest to satisfy modular operations' invariants. (The
underlying algorithms could accept looser bounds, but we reduce for
simplicity.) There's no particular reason to do this in constant time,
but we have the code for it, so we may as well.
- This additionally adds a missing check that num_bits(q) is a multiple
of 8. We otherwise don't compute the right answer. Verification
already rejected all 160-, 224-, and 256-bit keys, and we only
generate DSA parameters where the length of q matches some hash
function's length, so this is unlikely to cause anyone trouble.
- Use Montgomery reduction to perform the modular multiplication. This
could be optimized to save a couple Montgomery reductions as in ECDSA,
but DSA is deprecated, so I haven't bothered optimizing this.
- The reduction from g^k (mod p) to r = g^k (mod p) (mod q) is left
in variable time, but reversing it would require a discrete log
anyway. (The corresponding ECDSA operation is much easier to make
constant-time due to Hasse's theorem, though that's actually still a
TODO. I need to finish lifting EC_FELEM up the stack.)
Thanks to Keegan Ryan from NCC Group for reporting the modular addition issue
(CVE-2018-0495). The remainder is stuff I noticed along the way.
Update-Note: See the num_bits(q) change.

on them behaving like *some* consistent concrete value. The C spec

(If I'm reading it wrong and the compiler must behave as if there were a
consistent value in there, it's probably fine, but there's no sense in
risking compiler bugs on a subtle corner of things.)

Update-Note: This tweaks the SSL_shutdown behavior. OpenSSL's original
SSL_shutdown behavior was an incoherent mix of discarding the record and
rejecting it (it would return SSL_ERROR_SYSCALL but retrying the
operation would discard it). SSLeay appears to have intended to discard
it, so we previously "fixed" it actually discard.
However, this behavior is somewhat bizarre and means we skip over
unbounded data, which we typically try to avoid. If you are trying to
cleanly shutdown the TLS portion of your protocol, surely it is at a
point where additional data is a syntax error. I suspect I originally
did not realize that, because the discarded record did not properly
continue the loop, SSL_shutdown would appear as if it rejected the data,
and so it's unlikely anyone was relying on that behavior.
Discussion in https://github.com/openssl/openssl/pull/6340 suggests
(some of) upstream also prefers rejecting.

|alloca| is dangerous and poorly specified, according to any
description of |alloca|. It's also hard for some analysis tools to
reason about.
The code here assumed |alloca| is a macro, which isn't a valid
assumption. Depending on what which headers are included and what
toolchain is being used, |alloca| may or may not be defined as a macro,
and this might change over time if/when toolchains are updated. Or, we
might be doing static analysis and/or dynamic analysis with a different
configuration w.r.t. the availability of |alloca| than production
builds use.
Regardless, the |alloca| code path only kicked in when the inputs are
840 bits or smaller. Since the multi-prime RSA support was removed, for
interesting RSA key sizes the input will be at least 1024 bits and this
code path won't be triggered since powerbufLen will be larger than 3072
bytes in those cases. ECC inversion via Fermat's Little Theorem has its
own constant-time exponentiation so there are no cases where smaller
inputs need to be fast.
The RSAZ code avoids the |OPENSSL_malloc| for 2048-bit RSA keys.
Increasingly the RSAZ code won't be used though, since it will be
skipped over on Broadwell+ CPUs. Generalize the RSAZ stack allocation
to work for non-RSAZ code paths. In order to ensure this doesn't cause
too much stack usage on platforms where RSAZ wasn't already being used,
only do so on x86-64, which already has this large stack size
requirement due to RSAZ.
This change will make it easier to refactor |BN_mod_exp_mont_consttime|
to do that more safely and in a way that's more compatible with various
analysis tools.
This is also a step towards eliminating the |uintptr_t|-based alignment
hack.
Since this change increases the number of times |OPENSSL_free| is
skipped, I've added an explicit |OPENSSL_cleanse| to ensure the
zeroization is done. This should be done regardless of the other changes
here.

PKCS#12 encodes passwords as NUL-terminated UCS-2, so the empty password
is encoded as {0, 0}. Some implementations use the empty byte array for
"no password". OpenSSL considers a non-NULL password as {0, 0} and a
NULL password as {}. It then, in high-level PKCS#12 parsing code, tries
both options.
Match this behavior to appease pyOpenSSL's tests.

These are tied to OPENSSL_NO_OCSP in upstream but do not actually depend
on most of the OCSP machinery. The CRL invdate extension, in particular,
isn't associated with OCSP at all. cryptography.io gets upset if these
two extensions aren't parseable, and they're tiny.
I do not believe this actually affects anything beyond functions like
X509_get_ext_d2i. In particular, the list of NIDs for the criticality
check is elsewhere.

cryptography.io wants RSA_R_BLOCK_TYPE_IS_NOT_02, only used by the
ancient RSA_padding_check_SSLv23 function. Define it but never emit it.
Additionally, it's rather finicky about RSA_R_TOO_LARGE* errors. We
merged them in BoringSSL because having RSA_R_TOO_LARGE,
RSA_R_TOO_LARGE_FOR_MODULUS, and RSA_R_TOO_LARGE_FOR_KEY_SIZE is a
little silly. But since we don't expect well-behaved code to condition
on error codes anyway, perhaps that wasn't worth it. Split them back
up.
Looking through OpenSSL, there is a vague semantic difference:
RSA_R_DIGEST_TOO_BIG_FOR_RSA_KEY - Specifically emitted if a digest is
too big for PKCS#1 signing with this key.
RSA_R_DATA_TOO_LARGE_FOR_KEY_SIZE - You asked me to sign or encrypt a
digest/plaintext, but it's too big for this key.
RSA_R_DATA_TOO_LARGE_FOR_MODULUS - You gave me an RSA ciphertext or
signature and it is not fully reduced modulo N.
-OR-
The padding functions produced something that isn't reduced, but I
believe this is unreachable outside of RSA_NO_PADDING.
RSA_R_DATA_TOO_LARGE - Some low-level padding function was told to copy
a digest/plaintext into some buffer, but the buffer was too small. I
think this is basically unreachable.
-OR-
You asked me to verify a PSS signature, but I didn't need to bother
because the digest/salt parameters you picked were too big.
Update-Note: This depends on cl/196566462.

cryptography.io depends on this. Specifically, it assumes that any time

CMAC also requires an irreducible polynomial to represent GF(2^b).
However, one is indeed defined for 64-bit block ciphers such as 3DES.

Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a
complex OCSP mechanism and encourage the the unreliable server behavior
that hampers using OCSP stapling to fix revocation today. (OCSP
responses should not be fetched on-demand on a callback. They should be
managed like other server credentials and refreshed eagerly, so
temporary CA outage does not translate to loss of OCSP.)
But most of the APIs are byte-oriented anyway, so they're easy to
support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs.
The callback is benign on the client (an artifact of OpenSSL reading
OCSP and verifying certificates in the wrong order). On the server, it
encourages unreliability, but pyOpenSSL/cryptography.io depends on this.
Dcument that this is only for compatibility with legacy software.
Also tweak a few things for compatilibility. cryptography.io expects
SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's
signature was wrong, and cryptography.io tries to redefine
SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.

Update-Note: If anyone was using PKCS#12 passwords with non-ASCII

interpretting "correctly". If this breaks anything, we can add a
fallback to PKCS12_get_key_and_certs/PKCS12_parse, but OpenSSL 1.1.0
does not have such behavior. It only implements a fallback in the

This is slower, but constant-time. It intentionally omits the signed
digit optimization because we cannot be sure the doubling case will be
unreachable for all curves. This is a fallback generic implementation
for curves which we must support for compatibility but which are not
common or important enough to justify curve-specific work.
Before:
Did 814 ECDH P-384 operations in 1085384us (750.0 ops/sec)
Did 1430 ECDSA P-384 signing operations in 1081988us (1321.6 ops/sec)
Did 308 ECDH P-521 operations in 1057741us (291.2 ops/sec)
Did 539 ECDSA P-521 signing operations in 1049797us (513.4 ops/sec)
After:
Did 715 ECDH P-384 operations in 1080161us (661.9 ops/sec)
Did 1188 ECDSA P-384 verify operations in 1069567us (1110.7 ops/sec)
Did 275 ECDH P-521 operations in 1060503us (259.3 ops/sec)
Did 506 ECDSA P-521 signing operations in 1084739us (466.5 ops/sec)
But we're still faster than the old BIGNUM implementation. EC_FELEM
more than paid for both the loss of points_make_affine and this CL.

w=4 appears to be the correct answer for P-224 through P-521. There's
nominally some optimizations in here for 70- and 20-bit primes, but
that's absurd.

EC_POINT is split into the existing public EC_POINT (where the caller is
sanity-checked about group mismatches) and the low-level EC_RAW_POINT
(which, like EC_FELEM and EC_SCALAR, assume that is your problem and is
a plain old struct). Having both EC_POINT and EC_RAW_POINT is a little
silly, but we're going to want different type signatures for functions
which return void anyway (my plan is to lift a non-BIGNUM
get_affine_coordinates up through the ECDSA and ECDH code), so I think
it's fine.
This wasn't strictly necessary, but wnaf.c is a lot tidier now. Perf is
a wash; once we get up to this layer, it's only 8 entries in the table
so not particularly interesting.

Replace them with asserts and better justify why each of the internal
cases are not reachable. Also change the loop to count up to bits+1 so
it is obvious there is no memory error. (The previous loop shape made
more sense when ec_compute_wNAF would return a variable length
schedule.)

Along the way, add some utility functions for getting common things
(curves, hashes, etc.) in the names Wycheproof uses.
