[PATCH net 0/2] mptcp: sync the msk->sndbuf at accept() time

Posted by Matthieu Baerts (NGI0) 2 weeks ago

On passive MPTCP connections, the MPTCP socket send buffer doesn't have
the expected size at accept() time.

Patch 1 fixes the regression introduced in v6.7, while the following one
validates the fix in the selftests.
