| | | | | | | | | | Fixes builds gcc + Apple's assembler, working on reenabling builds with older OpenBSD releases. based on OpenSSL commit: https://git.openssl.org/?p=openssl.git;a=commitdiff;h=902b30df193afc3417a96ba72a81ed390bd50de3 ok miod@

* Provide tls_peer_cert_hash() which returns a hash of the raw certificatejsing2015-09-113-2/+92
| | | | | | | | | | | | | that was presented by the peer. The hash used is currently SHA256, however since we prefix the result with the hash name, we can change this in the future as the need arises. The same output can be generated by using: h=$(openssl x509 -outform der -in mycert.crt | sha256) printf "SHA256:${h}\n" ok beck@

| | | | | | | | so that we can provide asm labels for the memcpy/memset/__stack_smash_handler calls that it generates ab initio. Eliminate direct #includes of it. Make sure it's a dependency of all objects (unnecessary for asm, but close enough). ok deraadt@

Thanks for Georgi Guninski (guninski at guninski dot com) for mentioning the possibility of a weak (non prime) q value and providing a test case.

* Split tls_handshake() out from tls_accept/tls_connect. By doing this thejsing2015-09-105-59/+120
| | | | | | | | | | | | | | | tls_accept/tls_connect functions can be guaranteed to succeed or fail and will no longer return TLS_READ_AGAIN/TLS_WRITE_AGAIN. This also resolves the semantics of tls_accept_*. The tls_handshake() function now does I/O and can return TLS_READ_AGAIN/TLS_WRITE_AGAIN. Calls to tls_read() and tls_write() will trigger the handshake if it has not already completed, meaning that in many cases existing code will continue to work. Discussed over many coffees at l2k15. ok beck@ bluhm@
