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.
