2019-01-19Add handshake message type checking and special case certificate requests.jsing1-1/+30
Check that the handshake message type received matches that required by the state machine. However, thanks to poor state design in the TLSv1.3 RFC, there is no way to know if you're going to receive a certificate request message or not, hence we have to special case it and teach the receive handler how to handle this situation. Discussed at length with beck@ and tb@ during the hackathon. ok tb@
2019-01-19Tweak return value handling in the TLSv1.3 handshake code.jsing2-44/+47
The I/O paths are from the tls13_handshake_send_action() and tls13_handshake_recv_action() functions - both of these need to propagate I/O conditions (EOF, failure, want poll in, want poll out) up the stack, so we need to capture and return values <= 0. Use an I/O condition to indicate successful handshake completion. Also, the various send/recv functions are currently unimplemented, so return 0 (failure) rather than 1 (success). ok tb@

2019-01-19Provide a TLS record handling implementation.jsing3-2/+220
This is a self-contained struct and set of functions that knows how to decode and read a TLS record from data supplied via a read callback, and send itself via a write callback. This will soon be used to build the TLSv1.3 record layer handling code. ok beck@ tb@

2019-01-18Update regress following TLS extension renaming.jsing2-379/+378
2019-01-18Rename TLS extension handling to use less "hello".jsing4-220/+228
When the TLS extension code was rewritten, TLS extensions could only exist in ClientHello and ServerHello messages - as such, they were named in pairs of *_clienthello_{needs,build} which would be called by the client and *_clienthello_parse. Likewise for *_serverhello_{needs,build} which would be called by a server and *_serverhello_parse, which would be called by a client. Enter TLSv1.3 - TLS extensions can now exist in one of seven messages, with only certain types being allowed to appear in each, meaning the naming scheme no longer works. Instead, rename them to indicate the caller rather than the message type - this effectively means: clienthello_needs -> client_needs clienthello_build -> client_build clienthello_parse -> server_parse serverhello_needs -> server_needs serverhello_build -> server_build serverhello_parse -> client_parse ok beck@ tb@

ok jsing@ tb@
2019-01-17Provide an extensible buffer implementation that uses a read callback.jsing3-3/+148
The read callback returns a TLS13_IO_* value on EOF, failure, want pollin or want pollout, or a positive value indicating the number of bytes read. This will be used by upcoming TLSv1.3 handshake message and record processing code, both of which need the ability to read a fixed size header, before extending the buffer to the number of bytes specified in the header. ok beck@ tb@
2019-01-17Add support to enforce restrictions on where extensions can appearbeck2-12/+38
as per RFC8446 section 4.2. Recognized extensions that appear in an incorrect message must abort the handshake. ok jsing@
