* Compile fix on platforms with missing pthread_rwlock_t.Dmitry Kostjuchenko2017-02-031-0/+41
| | | | | | | | | | 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.

* CRYPTO_atomic_add(): use acquire release memory order rather than relaxedRichard Levitte2016-08-241-2/+2
| | | | | | | | For increments, the relaxed model is fine. For decrements, it's recommended to use the acquire release model. We therefore go for the latter. Reviewed-by: Andy Polyakov <appro@openssl.org>
