Summary
-------

When calling using TCP/TLS with an invalid CA certificate for the key in use and tlsdontverifyserver is set to no, Asterisk produces the error message:
ERROR[16872]: tcptls.c:199 handle_tcptls_connection: Certificate did not verify: certificate signature failure

This should cause the call to fail, but it does not. The call instead completes successfully.  This patch corrects that behavior as well as avoids a segfault if the remote end does not provide a certificate at all.


This addresses bug ASTERISK-20559.

Diffs

  trunk/main/tcptls.c 374904 

Diff: https://reviewboard.asterisk.org/r/2163/diff


Testing
-------

Ensured that the TCP/TLS call failed when expected and succeeded when expected.


Thanks,
