| | | | | | | | | | | | | | | | perform a proper shutdown by sending a "close notify" alert to the server. This allows s_time to benchmark a full TLS connection more accurately. Introduce a new flag called -no_shutdown to make s_time adopt the previous behavior (i.e. shut down the connection without notifying the server) so that comparisons can still be made with OpenSSL's version. The idea of using a flag (which replaces a #define) was suggested by bcook@. Thanks to millert@ and miod@ as well for their feedback on an earlier diff which resulted in this change. ok bcook@ 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@
