So a major reason, as you explained, for having per-thread DRBG's is to reduce contention. When threadA creates an SSL object, the parent DRBG will be the threadA one. Therefore you have to introducing locking, since threadA might create two SSL objects and they could end up being used in threadB and threadC and each need to reseed from their parent. In order to do that safely, threadA also has to do the locking to avoid conflict. That defeats the major gain of per-thread.
I think having the SSL object parent be whatever the *current* thread DRBG is seems like the best, if not only, way to go. _______________________________________________ openssl-project mailing list openssl-project@openssl.org https://mta.openssl.org/mailman/listinfo/openssl-project
