branch: master
commit d84d69dfbc5f64e9020ce38d2cbd60fe39cb27b9
Author: Robert Pluim <rpluim@gmail.com>
Commit: Robert Pluim <rpluim@gmail.com>
Don't crash if gnutls_handshake fails
In some situations involving Internet access not being fully
functional, gnutls_handshake returns a fatal error, which we were
ignoring, causing us to call gnutls_handshake again. Now we check for
the error and return it to the caller.
* src/gnutls.c (gnutls_try_handshake): Return immediately if
gnutls_handshake returns a fatal error (Bug#46709).
