* Set callbacks on the right tls ctx on accept.bcook2016-09-141-2/+2

* Maintain consistency with function naming.jsing2016-09-041-4/+4

* Add callback-based interface to libtls.bcook2016-09-041-10/+50
| | | | | | | This allows working with buffers and callback functions instead of directly on sockets or file descriptors. Original patch from Tobias Pape <tobias_at_netshed.de>. ok beck@
* Create contexts for server side SNI - these include the additional SSL_CTXjsing2016-08-221-1/+133
| | | | | | | | | that is required for certificate switching with libssl and the certificate itself so that we can match against the subject and SANs. Hook up the servername callback and switch to the appropriate SSL_CTX if we find a matching certificate. ok beck@

* Explicitly pass in an SSL_CTX * to the functions that operate on one,jsing2016-08-151-4/+5
| | | | | | | | | | | instead of assuming that they should use the one associated with the TLS context. This allows these functions to be used with the additional SSL contexts that are needed to support server-side SNI. Also rename tls_configure_keypair() to tls_configure_ssl_keypair(), so that these functions have a common prefix. ok reyk@

* Split tls_handshake() out from tls_accept/tls_connect. By doing this thejsing2015-09-101-30/+46
| | | | | | | | | | | | | | | 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@

* Improve libtls error messages.jsing2015-08-271-9/+9
| | | | | | | | | | | | The tls_set_error() function previously stored the errno but did nothing with it. Change tls_set_error() to append the strerror(3) of the stored errno so that we include useful information regarding failures. Provide a tls_set_errorx() function that does not store the errno or include strerror(3) in the error message. Call this function instead of tls_set_error() for errors where the errno value has no useful meaning. With feedback from and ok doug@
