[PATCH net 0/5] mptcp: misc fixes for v7.0-rc2

From: Matthieu Baerts (NGI0)

Date: Tue Mar 03 2026 - 05:56:42 EST


Here are various unrelated fixes:

- Patch 1: avoid bufferbloat in simult_flows selftest which can cause
instabilities. A fix for v5.10.

- Patches 2-3: reduce RM_ADDR lost by not sending it over the same
subflow as the one being removed, if possible. A fix for v5.13.

- Patches 4-5: avoid a WARN when using signal + subflow endpoints with a
subflow limit of 0, and removing such endpoints during an active
connection. A fix for v5.17.
