Subject: [PATCH net-next 3/4] selftests: mptcp: display warnings on one line
Date: Fri, 12 Feb 2021 15:20:29 -0800 [thread overview]
Message-ID: <20210212232030.377261-4-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20210212232030.377261-1-mathew.j.martineau@linux.intel.com>
From: Matthieu Baerts <matthieu.baerts@tessares.net>
Before we had this in case of SYN retransmissions:
(...)
# ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ]
# ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ]
# ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP ns2-60143c00-cDZWo4 SYNRX: MPTCP -> MPTCP: expect 11, got
# 13
# (duration 6221ms) [ OK ]
# ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ]
# ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ]
(...)
Now we have:
(...)
# ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ]
# ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ]
# ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP (duration 6221ms) [ OK ] WARN: SYNRX: expect 11, got 13
# ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ]
# ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ]
(...)
So we put everything on one line, keep the durations and "OK" aligned
and removed duplicated info to short the warning.
