Thank you for having reported the issue and having added MPTCP ML in Cc!

Just to avoid confusions: the "WARNING" you shared when running
'mptcp_connect.sh' selftest appeared before creating the first MPTCP
connection. It looks like there is no reference to MPTCP in the
calltraces. Also, because you have the same issue with nft_fib.sh, I
would say that this issue is not linked to MPTCP but rather to a recent
modification in the IPv6 stack.

By chance, did you start a "git bisect" to identify the commit causing
this issue?

Cheers,
Matt
