RAND_pseudo_bytes just calls RAND_bytes now and only returns 0 or 1. Switch all
callers within the library call the new one and use the simpler failure check.
This fixes a few error checks that no longer work (< 0) and some missing ones.

Turns out the EVP_CIPH_FLAG_CUSTOM_CIPHER ciphers (i.e. legacy EVP_CIPHER
AES-GCM) have a completely different return value setup than the normal ones
which are the standard one/zero. (Except that they never return zero; see
TODO.)
Fix checks in ssl/ and remove remnants of EVP_CIPH_FLAG_CUSTOM_CIPHER in ssl/
as we're using EVP_AEAD now.
See CHANGES entry added in upstream's 3da0ca796cae6625bd26418afe0a1dc47bf5a77f.

This makes SSLv23_method go through DTLS_ANY_VERSION's version negotiation
logic. This allows us to get rid of duplicate ClientHello logic. For
compatibility, SSL_METHOD is now split into SSL_PROTOCOL_METHOD and a version.
The legacy version-locked methods set min_version and max_version based this
version field to emulate the original semantics.
As a bonus, we can now handle fragmented ClientHello versions now.
Because SSLv23_method is a silly name, deprecate that too and introduce
TLS_method.

This commit fixes a number of crashes caused by malloc failures. They
were found using the -malloc-test=0 option to runner.go which runs tests
many times, causing a different allocation call to fail in each case.
(This test only works on Linux and only looks for crashes caused by
allocation failures, not memory leaks or other errors.)
This is not the complete set of crashes! More can be found by collecting
core dumps from running with -malloc-test=0.

This code isn't compiled in. It seems there was some half-baked logic for a
7-byte alert that includes more information about handshake messages
retransmit.
No such alert exists, and the code had a FIXME anyway. If it gets resurrected
in DTLS 1.3 or some extension, we can deal with it then.

Simplify all the cipher gathering logic. The set of supported ciphers is known,
so there is no need to determine if some cipher exists but doesn't work.

Update SSL_OP_ALL to account for SSL_OP_CRYPTOPRO_TLSEXT_BUG being gone,
and update ssl3_setup_write_buffer to account for SSL_MODE_CBC_RECORD_SPLITTING
rather than the now defunct SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.
Also remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is to allow for a buggy peer
which pads CBC with N bytes of value N rather than N+1 bytes of value N. This
quirk has been broken since CBC padding checks became constant-time, as
demonstrated by this attempt at a test. (Instead of just decrementing
padding_length, it needs to also keep track of a separate padding_value and not
decrement that one.)
https://boringssl-review.googlesource.com/#/c/1690/
(The quirk would also fall over anyway if the buggy client ever did a session
resumption; then the server speaks first rather than the client, and the quirk
triggered on reading the first encrypted record from the peer.)

09bd58d1f1c71ed7ea687d0295e23793ad3d98fa flipped a condition. Doing that
memset in the DTLS case breaks retransmits across a CCS and fails to memset in
the TLS case.
Strangely, it didn't break any tests, but I think that's a function of us
lacking renego tests. The sequence number doesn't seem to be used in the
initial handshake for TLS, so it stayed at zero. After a renego, that codepath
is relevant.

Since all AEAD ciphers now go through EVP_AEAD interface, the code which
uses EVP_Cipher interface no longer needs any of AEAD handling logic.
This also removes EVP_CTRL_AEAD_TLS1_AAD from GCM interface, which was
duplicating non-TLS-specific GCM logic and is not used anymore.

This patch adds server-side support for TLS_FALLBACK_SCSV (see
http://tools.ietf.org/html/draft-bmoeller-tls-downgrade-scsv-01).
|
|
This patch removes support for empty records (which is almost
universally disabled via SSL_OP_ALL) and adds optional support for 1/n-1
record splitting.
The latter is not enabled by default, since it's not typically used on
servers, but it should be enabled in web browsers since there are known
attacks in that case (see BEAST).

This change allows AEADs to be used in ssl/ to implement SSL/TLS
ciphersuites.
|
|
The previous version of the function made adding AEAD changes very
difficult. This change should be a semantic no-op - it should be purely
a cleanup.
|
|
Implement ChannelID as both a client and server.

Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
