2020-01-23Pass a CBB to TLSv1.3 send handlers.jsing4-50/+44
This avoids the need for each send handler to call tls13_handshake_msg_start() and tls13_handshake_msg_finish(). ok beck@ tb@
2020-01-22The length of the IV of EVP_chacha20 is currently 64 bits, not 96.tb1-3/+3
ok beck
2020-01-22Wire up the TLSv1.3 server.jsing3-6/+182
This currently only has enough code to handle fallback to the legacy TLS stack for TLSv1.2 or earlier, however allows for further development and testing. ok beck@
2020-01-22Pass a handshake message content CBS to TLSv1.3 receive handlers.jsing5-85/+70
This avoids every receive handler from having to get the handshake message content itself. Additionally, pull the trailing data check up so that each receive handler does not have to implement it. This makes the code more readable and reduces duplication. ok beck@ tb@

2020-01-22Enable the TLSv1.3 client in libssl.jsing1-2/+3
This also makes it available to clients that use libtls, including ftp(1) and nc(1). Note that this does not expose additional defines via public headers, which means that any code conditioning on defines like TLS1_3_VERSION or SSL_OP_NO_TLSv1_3 will not enable or use TLSv1.3. This approach is necessary since too many pieces of software assume that if TLS1_3_VERSION is available, other OpenSSL 1.1 API will also be available, which is not necessarily the case. ok beck@ tb@

This will as yet not do anything, until we turn it on in the lower level libraries. ok jsing@

Finished message has been received, a change cipher spec may be received and must be ignored. Add a flag to the record layer struct and set it at the appropriate moments during the handshake so that we will ignore it. ok jsing

2020-01-22Correctly set the legacy version when TLSv1.3 is building a client hello.jsing1-4/+11
The legacy version field is capped at TLSv1.2, however it may be lower than this if we are only choosing to use TLSv1.0 or TLSv1.1. ok beck@ tb@

ok jsing@
2020-01-22The legacy_record_version must be set to TLS1_2_VERSION excepttb4-9/+30
in the ClientHello where it may be set to TLS1_VERSION. Use the minimal supported version to decide whether we choose to do so or not. Use a sent hook to set it back TLS1_2_VERSION right after the ClientHello message is on the wire. ok beck jsing
2020-01-22Hook up the TLSv1.3 legacy shutdown code.jsing1-2/+2
Missed in an earlier commit.

2020-01-21Correct legacy fallback for TLSv1.3 client.jsing3-9/+30
When falling back to the legacy TLS client, in the case where a server has sent a TLS record that contains more than one handshake message, we also need to stash the unprocessed record data for later processing. Otherwise we end up with missing handshake data. ok beck@ tb@

2020-01-21Provide SSL_R_UNKNOWN.jsing3-5/+7
This allows us to indicate that the cause of the failure is unknown, rather than implying that it was an internal error when it was not. ok beck@
2020-01-21Clear and free the tls13_ctx that hangs off an SSL *s fromtb2-2/+8
SSL_{clear,free}(3). Make sure the handshake context is cleaned up completely: the hs_tls13 reacharound is taken care of by ssl3_{clear,free}(3). Add a missing tls13_handshake_msg_free() call to tls13_ctx_free(). ok beck jsing

2020-01-20Provide an error framework for use with the TLSv1.3 code.jsing5-7/+151
This is based on the libtls error handling code, but adds machine readable codes and subcodes. We then map these codes back to libssl error codes. ok beck@ inoguchi@
2020-01-20Update libtls config regress to include TLSv1.3.jsing1-9/+16
2020-01-20Add support for TLSv1.3 as a protocol to libtls.jsing4-11/+20
This makes tls_config_parse_protocols() recognise and handle "tlsv1.3". If TLSv1.3 is enabled libtls will also request libssl to enable it. ok beck@ tb@

2020-01-07If the client provides a TLS certificate and the user specifies abluhm1-5/+6
hash value on the nc(1) server command line, the netcat server must use the TLS context of the accepted socket for verification. As the listening socket was used instead, the verification was always successful. If the peer provides a certificate, there must be a hash. Make the hash verification fail safe. OK tb@

the file system as it has to connect to the UNIX domain client socket. The path of the latter is determined dynamically. Instead add a restrictive pledge(2) after connect(2). OK tb@
