| | | | | | For backward compatibility, the flags are redefined as 0. ok jsing@
* Remove last vestige of SSL_OP_NO_SSLv3 support.doug2015-10-251-4/+1
| | | | | | No part of LibreSSL checks for this flag any longer. ok jsing@
* Simplify ssl23_get_client_hello error handling.doug2015-10-251-26/+26
| | | | | | | | | | ssl23_get_client_hello sets type=1 on error and continues processing. It should return an error immediately to simplify things. This also allows us to start removing the last of SSL_OP_NO_SSL*. Added extra paranoia for s->version to make sure it is set properly. ok jsing@

* SSL_new(): fix ref counting and memory leak in error path.doug2015-10-031-8/+3
| | | | | | | | | | Rather than a half-hearted attempt to free up resources and fix ref counting at the SSL_CTX level, let SSL_free() do its job. This diff got lost in the shuffle somewhere. It's from last year. Ref counting error reported by Parakleta in github ticket #51. Thanks! ok jsing@, beck@

* Stop generating private keys in a network buffer.jsing2015-09-131-29/+29
| | | | | | | | | | The current client key exchange code generates DH and ECDH keys into the same buffer that we use to send data to the network - stop doing this and malloc() a new buffer, which we explicit_bzero() and free() on return. This also benefits from ASLR and means that the keys are no longer generated in a well known location. ok beck@
* Use ECDH_size() instead of rolling our own.jsing2015-09-132-12/+11

* The *_accept() functions increment in_handshake at the start of the function,jsing2015-09-132-19/+30
| | | | | | | | then decrement it and call a callback on exit from the function. As such, these functions should not return in the middle, otherwise in_handshake is never decremented and the callback never called. ok beck@ "with many sighs" miod@
* If we have hardware acceleration for AES, prefer AES as a symmetric cipherjsing2015-09-131-7/+30
| | | | | | over CHACHA20. Otherwise, prefer CHACHA20 with AES second. ok beck@ miod@
* Split ssl3_send_client_key_exchange() (387 lines of code) into fivejsing2015-09-121-327/+351
| | | | | | | | | functions. The original was written as a huge if/else if chain - split out the handling for each key exchange type. This allows us to reduce two levels of indentation, make the code far more readable and have single return paths so that we can simplify clean up. ok beck@

| | | | | | | | ssl3_send_client_key_exchange() is effectively identical, in fact it has a number of bug fixes and improvements that never got merged into the DTLS copy of the code. Flenses another 264 lines of code. ok beck@
