Previously, the RAND_DRBG_uninstantiate() call was not exactly inverse to RAND_DRBG_instantiate(), because some important member values of the drbg->ctr member where cleared. Now these values are restored internally. Signed-off-by:

Every DRBG now supports automatic reseeding not only after a given number of generate requests, but also after a specified time interval. Signed-off-by:

Dr. Matthias St. Pierre authored
A third shared DRBG is added, the so called master DRBG. Its sole purpose is to reseed the two other shared DRBGs, the public and the private DRBG. The randomness for the master DRBG is either pulled from the os entropy sources, or added by the application using the RAND_add() call. The master DRBG reseeds itself automatically after a given number of generate requests, but can also be reseeded using RAND_seed() or RAND_add(). A reseeding of the master DRBG is automatically propagated to the public and private DRBG. This construction fixes the problem, that up to now the randomness provided by RAND_add() was added only to the public and not to the private DRBG. Signed-off-by:

Flush following the CCS after an HRR. Only flush the HRR if middlebox compat is turned off. Reviewed-by:

Matt Caswell authored
Normally we flush immediately after writing the ClientHello. However if we are going to write a CCS immediately because we've got early_data to come, then we should move the flush until after the CCS. Reviewed-by:

The CCS may be sent at different times based on whether or not we sent an HRR earlier. In order to make that decision this commit also updates things to make sure we remember whether an HRR was used or not. Reviewed-by:

The new ServerHello format is essentially now the same as the old TLSv1.2 one, but it must additionally include supported_versions. The version field is fixed at TLSv1.2, and the version negotiation happens solely via supported_versions. Reviewed-by:

If OPENSSL_init_crypto() hasn't been called yet when ERR_get_state() is called, it need to be called early, so the base initialization is done. On some platforms (those who support DSO functionality and don't define OPENSSL_USE_NODELETE), that includes a call of ERR_set_mark(), which calls this function again. Furthermore, we know that ossl_init_thread_start(), which is called later in ERR_get_state(), calls OPENSSL_init_crypto(0, NULL), except that's too late. Here's what happens without an early call of OPENSSL_init_crypto(): => ERR_get_state(): => CRYPTO_THREAD_get_local(): <= NULL; # no state is found, so it gets allocated. => ossl_init_thread_start(): => OPENSSL_init_crypto(): # Here, base_inited is set to 1 # before ERR_set_mark() call => ERR_set_mark(): => ERR_get_state(): => CRYPTO_THREAD_get_local(): <= NULL; # no state is found, so it gets allocated!!!!! => ossl_init_thread_start(): => OPENSSL_init_crypto(): # base_inited is 1, # so no more init to be done <= 1 <= => CRYPTO_thread_set_local(): <= <= <= <= 1 <= => CRYPTO_thread_set_local() # previous value removed! <= Result: double allocation, and we have a leak. By calling the base OPENSSL_init_crypto() early, we get this instead: => ERR_get_state(): => OPENSSL_init_crypto(): # Here, base_inited is set to 1 # before ERR_set_mark() call => ERR_set_mark(): => ERR_get_state(): => OPENSSL_init_crypto(): # base_inited is 1, # so no more init to be done <= 1 => CRYPTO_THREAD_get_local(): <= NULL; # no state is found, so it gets allocated # let's assume we got 0xDEADBEEF => ossl_init_thread_start(): => OPENSSL_init_crypto(): # base_inited is 1, # so no more init to be done <= 1 <= 1 => CRYPTO_thread_set_local(): <= <= <= <= 1 => CRYPTO_THREAD_get_local(): <= 0xDEADBEEF <= 0xDEADBEEF Result: no leak.
