[PATCH net 0/5] mptcp: misc. fixes for v6.7

From: Matthieu Baerts
Date: Mon Nov 13 2023 - 18:16:50 EST


Here are a few fixes related to MPTCP:

- Patch 1 limits GSO max size to ~64K when MPTCP is being used due to a
spec limit. 'gso_max_size' can exceed the max value supported by MPTCP
since v5.19.

- Patch 2 fixes a possible NULL pointer dereference on close that can
happen since v6.7-rc1.

- Patch 3 avoids sending a RM_ADDR when the corresponding address is no
longer tracked locally. A regression for a fix backported to v5.19.

- Patch 4 adds a missing lock when changing the IP TOS with setsockopt().
A fix for v5.17.

- Patch 5 fixes an expectation when running MPTCP Join selftest with the
checksum option (-C). An issue present since v6.1.
