Please next time join the test with the fix, otherwise this patch alone will not work. Also, if you use 'mptcp*' prefix in the subject, please don't Cc the netdev mailing list.

A more efficient way of validating that is to add a packetdrill test instead of increasing the complexity of the "sockopt" test to validate a connection issue. Can you add your new test in the MPTCP fork [1], and validate it with: # cd gtests/net # ./packetdrill/run_all.py -lv mptcp/fastopen/.pkt [1] https://github.com/multipath-tcp/packetdrill/ > Signed-off-by: T S Rameshkumar If LLM is used, you need to add the Assisted-by tag: https://docs.kernel.org/process/coding-assistants.html Cheers, Matt -- Sponsored by the NGI0 Core fund.
