From: Matthieu Baerts (NGI0)
Date: Tue Nov 18 2025 - 02:25:35 EST
Here are various unrelated fixes:
- Patch 1: Fix window space computation for fallback connections which
can affect ACK generation. A fix for v5.11.
- Patch 2: Avoid unneeded subflow-level drops due to unsynced received
window. A fix for v5.11.
- Patch 3: Avoid premature close for fallback connections with PREEMPT
kernels. A fix for v5.12.
- Patch 4: Reset instead of fallback in case of data in the MPTCP
out-of-order queue. A fix for v5.7.
- Patches 5-7: Avoid also sending "plain" TCP reset when closing with an
MP_FASTCLOSE. A fix for v6.1.
- Patches 8-9: Longer timeout for background connections in MPTCP Join
selftests. An additional fix for recent patches for v5.13/v6.1.
- Patches 10-11: Fix typo in a check introduce in a recent refactoring.
A fix for v6.15.
