7027d25c6b Also add a no-op stub for OPENSSL_config.
Apparently OpenSSL's API is made entirely of initialization functions.
Some external libraries like to initialize with OPENSSL_config instead.

e5aa791a1c Add a few more no-op stubs for cURL compatibility.
With these stubs, cURL should not need any BoringSSL #ifdefs at all,
except for their OCSP #ifdefs (which can switch to the more generally
useful OPENSSL_NO_OCSP) and the workaround for wincrypt.h macro
collisions. That we intentionally leave to the consumer rather than add
a partial hack that makes the build sensitive to include order.

(I'll send them a patch upstream once this cycles in.)

232127d245 Fold EC_GROUP_new_curve_GFp and EC_GROUP_set_generator into a EC_GROUP_new_arbitrary.
This is only for Conscrypt which always calls the pair in succession. (Indeed
it wouldn't make any sense to not call it.) Remove those two APIs and replace
with a single merged API. This way incomplete EC_GROUPs never escape outside
our API boundary and EC_GROUPs may *finally* be made immutable.

Also add a test for this to make sure I didn't mess it up.

Add a temporary BORINGSSL_201512 define to ease the transition for Conscrypt.

OpenSSL upstream did a bulk reformat. We still have some files that have
the old OpenSSL style and this makes applying patches to them more
manual, and thus more error-prone, than it should be.

This change is the result of running

in the enumerated directories. A few files were in BoringSSL style and
have not been touched.

This change should be formatting only; no semantic difference.

62882187c9 Update comments to better document in-place semantics.
(Comment-only change; no functional difference.)

Some code was broken by the |d2i_ECDSA_SIG| change in 87897a8c. It was
passing in a pointer to an existing |ECDSA_SIG| as the first argument
and then simply assuming that the structure would be updated in place.
The comments on the function suggested that this was reasonable.

This change updates the comments that use similar wording to either note
that the function will never update in-place, or else to note that
depending on that is a bad idea for the future.

I've also audited all the uses of these functions that I can find and,
in addition to the one case with |d2i_ECDSA_SIG|, there are several
users of |d2i_PrivateKey| that could become a problem in the future.
I'll try to fix them before it does become an issue.

2a0b391ac9 Rewrite ssl3_send_server_key_exchange to use CBB.
There is some messiness around saving and restoring the CBB, but this is
still significantly clearer.

Note that the BUF_MEM_grow line is gone in favor of a fixed CBB like the
other functions ported thus far. This line was never necessary as
init_buf is initialized to 16k and none of our key exchanges get that
large. (The largest one can get is DHE_RSA. Even so, it'd take a roughly
30k-bit DH group with a 30k-bit RSA key.)

Having such limits and tight assumptions on init_buf's initial size is
poor (but on par for the old code which usually just blindly assumed the
message would not get too large) and the size of the certificate chain
is much less obviously bounded, so those BUF_MEM_grows can't easily go.

My current plan is convert everything but those which legitimately need
BUF_MEM_grow to CBB, then atomically convert the rest, remove init_buf,
and switch everything to non-fixed CBBs. This will hopefully also
simplify async resumption. In the meantime, having a story for
resumption means the future atomic change is smaller and, more
importantly, relieves some complexity budget in the ServerKeyExchange
code for adding Curve25519.

b965c63acb Reject calls to X509_verify_cert that have not been reinitialised
The function X509_verify_cert checks the value of |ctx->chain| at the
beginning, and if it is NULL then it initialises it, along with the value
of |ctx->untrusted|. The normal way to use X509_verify_cert() is to first
call X509_STORE_CTX_init(); then set up various parameters etc; then call
X509_verify_cert(); then check the results; and finally call
X509_STORE_CTX_cleanup(). The initial call to X509_STORE_CTX_init() sets
|ctx->chain| to NULL. The only place in the OpenSSL codebase  where
|ctx->chain| is set to anything other than a non NULL value is in
X509_verify_cert itself. Therefore the only ways that |ctx->chain| could be
non NULL on entry to X509_verify_cert is if one of the following occurs:
1) An application calls X509_verify_cert() twice without re-initialising
in between.
2) An application reaches inside the X509_STORE_CTX structure and changes
the value of |ctx->chain| directly.

With regards to the second of these, we should discount this - it should
not be supported to allow this.

With regards to the first of these, the documentation is not exactly
crystal clear, but the implication is that you must call
X509_STORE_CTX_init() before each call to X509_verify_cert(). If you fail
to do this then, at best, the results would be undefined.

Calling X509_verify_cert() with |ctx->chain| set to a non NULL value is
likely to have unexpected results, and could be dangerous. This commit
changes the behaviour of X509_verify_cert() so that it causes an error if
|ctx->chain| is anything other than NULL (because this indicates that we
have not been initialised properly). It also clarifies the associated
documentation.

3f5b43df07 Simplify RSA key exchange padding check.
This check was fixed a while ago, but it could have been much simpler.

In the RSA key exchange, the expected size of the output is known, making the
padding check much simpler. There isn't any use in exporting the more general
RSA_message_index_PKCS1_type_2. (Without knowing the expected size, any
integrity check or swap to randomness or other mitigation is basically doomed
to fail.)

Verified with the valgrind uninitialized memory trick that we're still
constant-time.

Also update rsa.h to recommend against using the PKCS#1 v1.5 schemes.

There is a non-trivial performance hit, but this cipher doesn't matter much and
the stitched mode code reaches into MD5_CTX and RC4_KEY in somewhat unfortunate
ways.

1741a9d143 Save some mallocs in computing the MAC for e_tls.c.
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).

a01deee96b Make CBB_len relative to its argument.
Rather than the length of the top-level CBB, which is kind of odd when ASN.1
length prefixes are not yet determined, return the number of bytes written to
the CBB so far. This can be computed without increasing the size of CBB at all.
Have offset and pending_*.

This means functions which take in a CBB as argument will not be sensitive to
whether the CBB is a top-level or child CBB. The extensions logic had to be
careful to only ever compare differences of lengths, which was awkward.

The reversal will also allow for the following pattern in the future, once
CBB_add_space is split into, say, CBB_reserve and CBB_did_write and we add a
CBB_data:

  uint8_t *signature;
  size_t signature_len = 0;
  if (!CBB_add_asn1(out, &cert, CBB_ASN1_SEQUENCE) ||
      /* Emit the TBSCertificate. */
      !CBB_add_asn1(&cert, &tbs_cert, CBS_ASN1_SEQUENCE) ||
      !CBB_add_tbs_cert_stuff(&tbs_cert, stuff) ||
      !CBB_flush(&cert) ||
      /* Feed it into md_ctx. */
      !EVP_DigestSignInit(&md_ctx, NULL, EVP_sha256(), NULL, pkey) ||
      !EVP_DigestSignUpdate(&md_ctx, CBB_data(&cert), CBB_len(&cert)) ||
      /* Emit the signature algorithm. */
      !CBB_add_asn1(&cert, &sig_alg, CBS_ASN1_SEQUENCE) ||
      !CBB_add_sigalg_stuff(&sig_alg, other_stuff) ||
      /* Emit the signature. */
      !EVP_DigestSignFinal(&md_ctx, NULL, &signature_len) ||
      !CBB_reserve(&cert, &signature, signature_len) ||
      !EVP_DigestSignFinal(&md_ctx, signature, &signature_len) ||
      !CBB_did_write(&cert, signature_len)) {
    goto err;
  }

(Were TBSCertificate not the first field, we'd still have to sample
CBB_len(&cert), but at least that's reasonable straight-forward. The
alternative would be if CBB_data and CBB_len somehow worked on
recently-invalidated CBBs, but that would go wrong once the invalidated CBB's
parent flushed and possibly shifts everything.)

And similar for signing ServerKeyExchange.

5a19d7dfa8 Use the straight-forward ROTATE macro.
I would hope any sensible compiler would recognize the rotation. (If
not, we should at least pull this into crypto/internal.h.) Confirmed
that clang at least produces the exact same instructions for
sha256_block_data_order for release + NO_ASM. This is also mostly moot
as SHA-1 and SHA-256 both have assembly versions on x86 that sidestep
most of this.

For the digests, take it out of md32_common.h since it doesn't use the
macro. md32_common.h isn't sure whether it's a multiply-included header
or not. It should be, but it has an #include guard (doesn't quite do
what you'd want) and will get HOST_c2l, etc., confused if one tries to
include it twice.

8a58933db0 Remove the CRYPTO_EX_new callback.
This callback is never used. The one caller I've ever seen is in Android
code which isn't built with BoringSSL and it was a no-op.

It also doesn't actually make much sense. A callback cannot reasonably
assume that it sees every, say, SSL_CTX created because the index may be
registered after the first SSL_CTX is created. Nor is there any point in
an EX_DATA consumer in one file knowing about an SSL_CTX created in
completely unrelated code.

Replace all the pointers with a typedef to int*. This will ensure code
which passes NULL or 0 continues to compile while breaking code which
passes an actual function.

This simplifies some object creation functions which now needn't worry
about CRYPTO_new_ex_data failing. (Also avoids bouncing on the lock, but
it's taking a read lock, so this doesn't really matter.)

Without |EC_POINTs_mul|, there's never more than one variable point
passed to a |EC_METHOD|'s |mul| method. This allows them to be
simplified considerably. In this commit, the p256-x86_64 implementation
has been simplified to eliminate the heap allocation and looping
related that was previously necessary to deal with the possibility of
there being multiple input points. The other implementations were left
mostly as-is; they should be similarly simplified in the future.

The fixes aren't exactly the same. In particular, the comments "This is

to |ecp_nistz256_mult_precompute| (which isn't in BoringSSL) were

cd24a39f1b Limit DHE groups to 4096-bit.
dh.c had a 10k-bit limit but it wasn't quite correctly enforced. However,
that's still 1.12s of jank on the IO thread, which is too long. Since the SSL
code consumes DHE groups from the network, it should be responsible for
enforcing what sanity it needs on them.

Costs of various bit lengths on 2013 Macbook Air:
1024 - 1.4ms
2048 - 14ms
3072 - 24ms
4096 - 55ms
5000 - 160ms
10000 - 1.12s

UMA says that DHE groups are 0.2% 4096-bit and otherwise are 5.5% 2048-bit and
94% 1024-bit and some noise. Set the limit to 4096-bit to be conservative,
although that's already quite a lot of jank.

5d5e39f5d2 Remove non-ASM version of |bn_mul_mont| in bn/generic.c.
When building in OPENSSL_NO_ASM mode, MSVC complains about unreachable
code. The redundant initialization of |i| is the main problem. The
skipping of the first test of the condition |i < num| with |goto| was
also confusing.

It turns out that |bn_mul_mont| is only called when assembly language
optimizations are available, but in that case the assmebly language
versions will always be used instead. Although this code will be
compiled in |OPENSSL_NO_ASM| builds, it is never called in
|OPENSSL_NO_ASM| builds. Thus, it can just be removed.

|SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| is also useful when the C

If support for ARM processors that don't support unaligned access is
important, then it might be better to condition the enabling of

This removes a sharp corner in the API where |ECDH_compute_key| assumed
that callers were either using ephemeral keys, or else had already
checked that the public key was on the curve.

A public key that's not on the curve can be in a small subgroup and thus
the result can leak information about the private key.

This change causes |EC_POINT_set_affine_coordinates_GFp| to require that
points are on the curve. |EC_POINT_oct2point| already does this.

ac9404c3a8 Improve crypto/digest/md32_common.h mechanism.
The documentation in md32_common.h is now (more) correct with respect
to the most important details of the layout of |HASH_CTX|. The
documentation explaining why sha512.c doesn't use md32_common.h is now
more accurate as well.

Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer
to the |HASH_CTX| and the assembly language implementations took a
pointer to the hash state |h| member of |HASH_CTX|. (This worked
because |h| is always the first member of |HASH_CTX|.) Now, the C
implementations take a pointer directly to |h| too.

The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to
be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash
state in an array. This will break source compatibility with any
external code that accesses the hash state directly, but will not
affect binary compatibility.

The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type
|const uint8_t *|; previously it was |void *| and all implementations
had a |uint8_t *data| variable to access it as an array of bytes.

This change paves the way for future refactorings such as automatically
generating the |*_Init| functions and/or sharing one I-U-F
implementation across all digest algorithms.

3fc138eccd Don't bother sampling __func__.

This shaves 100kb from a release build of the bssl tool.

In doing so, put an unused function code parameter back into ERR_put_error to

OpenSSL compatibility with anything which uses ERR_LIB_USER or

00461cf201 Improve crypto/digest/md32_common.h mechanism.
The documentation in md32_common.h is now (more) correct with respect
to the most important details of the layout of |HASH_CTX|. The
documentation explaining why sha512.c doesn't use md32_common.h is now
more accurate as well.

Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer
to the |HASH_CTX| and the assembly language implementations tool a
pointer to the hash state |h| member of |HASH_CTX|. (This worked
because |h| is always the first member of |HASH_CTX|.) Now, the C
implementations take a pointer directly to |h| too.

The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to
be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash
state in an array. This will break source compatibility with any
external code that accesses the hash state directly, but will not
affect binary compatibility.

The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type
|const uint8_t *|; previously it was |void *| and all implementations
had a |uint8_t *data| variable to access it as an array of bytes.

This change paves the way for future refactorings such as automatically
generating the |*_Init| functions and/or sharing one I-U-F
implementation across all digest algorithms.

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.

278d34234f Get rid of all compiler version checks in perlasm files.
Since we pre-generate our perlasm, having the output of these files be
sensitive to the environment the run in is unhelpful. It would be bad to
suddenly change what features we do or don't compile in whenever workstations'
toolchains change or if developers do or don't have CC variables set.

Previously, all compiler-version-gated features were turned on in
https://boringssl-review.googlesource.com/6260, but this broke the build. I
also wasn't thorough enough in gathering performance numbers. So, flip them all
to off instead. I'll enable them one-by-one as they're tested.

This should result in no change to generated assembly.
