From 857898eb4b28daf3faca3ae334c78b2bb141475e Mon Sep 17 00:00:00 2001 From: Matthieu Baerts matthieu.baerts@tessares.net Date: Wed, 9 Feb 2022 17:25:07 -0800 Subject: [PATCH] selftests: mptcp: add missing join check
This function also writes the name of the test with its ID, making clear a new test has been executed.
Without that, the ADD_ADDR results from this test was appended at the end of the previous test causing confusions. Especially when the second test was failing, we had:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] add[fail] got 2 ADD_ADDR[s] expected 3
In fact, this 17th test was OK but not the 18th one.
Now we have:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] 18 signal addresses race test syn[fail] got 2 JOIN[s] syn expected 3 - synack[fail] got 2 JOIN[s] synack expected - ack[fail] got 2 JOIN[s] ack expected 3 add[fail] got 2 ADD_ADDR[s] expected 3
