The intention of the removed code was to check if the previous operation carried. However this does not work. The "mask" value always ends up being a constant and is all ones - thus it has no effect. This check is no longer required because of the previous commit. Reviewed-by:

In TLS mode of operation the padding value "pad" is obtained along with the maximum possible padding value "maxpad". If pad > maxpad then the data is invalid. However we must continue anyway because this is constant time code. We calculate the payload length like this: inp_len = len - (SHA_DIGEST_LENGTH + pad + 1); However if pad is invalid then inp_len ends up -ve (actually large +ve because it is a size_t). Later we do this: /* verify HMAC */ out += inp_len; len -= inp_len; This ends up with "out" pointing before the buffer which is undefined behaviour. Next we calculate "p" like this: unsigned char *p = out + len - 1 - maxpad - SHA256_DIGEST_LENGTH; Because of the "out + len" term the -ve inp_len value is cancelled out so "p" points to valid memory (although technically the pointer arithmetic is undefined behaviour again). We only ever then dereference "p" and never "out" directly so there is never an invalid read based on the bad pointer - so there is no security issue. This commit fixes the undefined behaviour by ensuring we use maxpad in place of pad, if the supplied pad is invalid. With thanks to Brian Carpenter for reporting this issue. Reviewed-by:

This is an inherent weakness of the padding mode. We can't make the implementation constant time (see the comments in rsa_pk1.c), so add a warning to the docs. Reviewed-by:

TAP::Parser::Aggregator::has_errors may return any number, not just 0 and 1. With Perl on VMS, any number from 2 and on is interpreted as a VMS status, the 3 lower bits are the encoded severity (1 = SUCCESS, for example), so depending on what has_errors returns, a test failure might be interpreted as a success. Therefore, it's better to make sure the exit code is 0 or 1, nothing else (they are special on VMS, and mean SUCCESS or FAILURE, to match Unix conventions). Reviewed-by:

The value of BIO_CTRL_DGRAM_SET_PEEK_MODE was clashing with the value for BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE. In an SCTP enabled build BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE was used unconditionally with the reasoning that it would be ignored if SCTP wasn't in use. Unfortunately due to this clash, this wasn't the case. The BIO ended up going into peek mode and was continually reading the same data over and over - throwing it away as a replay.

ECDHE is not properly defined for SSLv3. Commit fe55c4a2 prevented ECDHE from being selected in that protocol. However, historically, servers do still select ECDHE anyway so that commit causes interoperability problems. Clients that previously worked when talking to an SSLv3 server could now fail. This commit introduces an exception which enables a client to continue in SSLv3 if the server selected ECDHE. (cherry picked from commit 8af91fd9 ) Reviewed-by:

gcc's -Wextra pulls in -Wold-style-declaration, which triggers when a declaration has a storage-class specifier as a non-initial qualifier. The ISO C formal grammar requires the storage-class to be the first component of the declaration, if present. Seeint as the register storage-class specifier does not really have any effect anymore with modern compilers, remove it entirely while we're here, instead of fixing up the order. Interestingly, the gcc devteam warnings do not pull in -Wextra, though the clang ones do. [extended tests] Reviewed-by:

clang already has it; let's flip the switch and deal with the fallout. Exclude -Wunused-parameter, as we have many places where we keep unused parameters to conform to a uniform vtable-like interface. Also exclude -Wmissing-field-initializers; it's okay to rely on the standard-mandated behavior of filling out with 0/NULL. Reviewed-by:
