commit 6c8880fcaa5c45355179b759c1d11737775e31fc upstream.
MPTCP selftests are using TCP SYN Cookies for quite a while now, since v5.9.
Some CIs don't have this config option enabled and this is causing issues in the tests:
# ns1 MPTCP -> ns1 (10.0.1.1:10000 ) MPTCP (duration 167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory # [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
There is no impact in the results but the test is not doing what it is supposed to do.
