Validate the IP address in the certificate for DNS-over-TLS in strict mode when GnuTLS is used. As this is not yet the case in contrast to the documentation.
Increase the required version to ensure TLS 1.3 is always supported when using GnuTLS for DNS-over-TLS and allow further changes to use recent API additions.
Instead of having a context and/or trusted CA list per server this is now moved to the server. Ensures future TLS configuration options are global instead of per server.
This reverts commit 18bddeaaf2.
Revert this because it does not take the OpenSSL internal read pointer
into considoration. Resulting in padding in packetdata and therefore
broken SSL connections.
The references to the dns_server are now setup after the tls connection is setup.
This ensures that the stream got fully stopped when the initial tls setup failed
instead of having the unref being blocked by the reference to the stream by the server.
Therefore on_stream_io would no longer be called with a half setup encrypted connection.
Fixes the issue reported in #9838.
To decreae latency this add support for TFO and TLS Session Tickets. As OpenSSL wouldn't let you easily set a different function all written data is temporarily cached and therefore needs to be flushed after each SSL function which can write data.
This provides basic OpenSSL support without optimizations like TCP Fast Open and TLS Session Tickets.
Notice only a single SSL library can be enabled at a time and therefore journald functions provided by GnuTLS will be disabled when using OpenSSL.
Fixes#9531
During handshake and TLS session closing, messages needs to be exchanged. Therefore this patch overrides the requested IO events for the TCP stream when the TLS is waiting for sending or receiving of messages during theses periods. This fixes issues with correctly closing the TLS stream and prevents the handshake from hanging in rare cases (not seen yet).
During the transition from system functions using errno to our own read and write functions with negative return codes some errors where introduced. This patch correctly convert errno to negative return codes for read and write and fix checks still using errno instead of the return code.
Closes#9283
