Subject: [PATCH 13/17] drbd: don't retry connection if peers do not agree on "authentication" settings
Date: Thu, 20 Dec 2018 17:23:40 +0100	[thread overview]
Message-ID: <20181220162344.8430-14-lars.ellenberg@linbit.com> (raw)
In-Reply-To: <20181220162344.8430-1-lars.ellenberg@linbit.com>

emma: "Unexpected data packet AuthChallenge (0x0010)"
 ava: "expected AuthChallenge packet, received: ReportProtocol (0x000b)"
      "Authentication of peer failed, trying again."

Pattern repeats.

There is no point in retrying the handshake,
if we expect to receive an AuthChallenge,
but the peer is not even configured to expect or use a shared secret.
