[PATCH net 0/2] mptcp: fix duplicate data handling

Posted by Matthieu Baerts (NGI0) 3 months ago

In some cases, the subflow-level's copied_seq counter was incorrectly
increased, leading to an unexpected subflow reset.

Patch 1/2 fixes the RCVPRUNED MIB counter that was attached to the wrong
event since its introduction in v5.14, backported to v5.11.

Patch 2/2 fixes the copied_seq counter issues, is present since v5.10.
