EVP_CIPH_FLAG_LENGTH_BITS flag for CFB1 has been broken with the introduction of the is_partially_overlapping() check that did not take it into the account (treating number of bits passed as bytes). This remedies that and allows this flag to work as intended. Reviewed-by:

While it's always safe to read |SSL_MAX_SSL_SESSION_ID_LENGTH| bytes from an |SSL_SESSION|'s |session_id| array, the hash function would do so with without considering if all those bytes had been written to. This change checks |session_id_length| before possibly reading uninitialised memory. Since the result of the hash function was already attacker controlled, and since a lookup of a short session ID will always fail, it doesn't appear that this is anything more than a clean up. In particular, |ssl_get_prev_session| uses a stack-allocated placeholder |SSL_SESSION| as a lookup key, so the |session_id| array may be uninitialised. This was originally found with libFuzzer and MSan in https://boringssl.googlesource.com/boringssl/+/e976e4349d693b4bbb97e1694f45be5a1b22c8c7 , then by Robert Swiecki with honggfuzz and MSan here. Thanks to both. Reviewed-by:

Fix compilation on platforms with missing pthread_rwlock_t implementation by replacing it with pthread_mutex_t. An example of such platform can be Android OS 2.0 - 2.1, API level 5 (Eclair), Android NDK platform - android-5 where pthread_rwlock_t is not implemented and is missing in pthread.h. In case of missing pthread_rwlock_t implementation CRYPTO_RWLOCK will work as exclusive lock in write-only mode of pthread_rwlock_t lock. The implementation based on pthread_mutex_t must be using PTHREAD_MUTEX_RECURSIVE mode to be compatible with recursive behavior of pthread_rwlock_rdlock. Reviewed-by:

The BIGNUM behaviour is supposed to be "consistent" when going into and out of APIs, where "consistent" means 'top' is set minimally and that 'neg' (negative) is not set if the BIGNUM is zero (which is iff 'top' is zero, due to the previous point). The BN_DEBUG testing (make test) caught the cases that this patch corrects. Note, bn_correct_top() could have been used instead, but that is intended for where 'top' is expected to (sometimes) require adjustment after direct word-array manipulation, and so is heavier-weight. Here, we are just catching the negative-zero case, so we test and correct for that explicitly, in-place. Change-Id: Iddefbd3c28a13d935648932beebcc765d5b85ae7 Signed-off-by:

On error, i2o_SCT_signature() and i2o_SCT() free a pointer that may have wandered off from the start of the allocated block (not currently true for i2o_SCT_signature(), but has that potential as the code may change. To avoid this, save away the start of the allocated block and free that instead. Thanks to Guido Vranken for reporting this issue. Reviewed-by:
