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.
