A fix for v5.7. - Patch 2: Avoid copying thmac which will not be used and could be uninitialised. A fix for v5.7. - Patch 3: Re-set the request backup flag when SYN cookies are used. A fix for v5.9. - Patch 4: Drop pending ADD_ADDR when removing ID0, and avoid a WARN. A fix for v5.13. - Patch 5: Handle invalid suboptions where the checksum is requested in the MP_CAPABLE 4th ACK with data, but not added in the option. A fix for v5.14. - Patch 6: Fix a use-after-free in the selftests that could lead to false positive. A fix for v5.17. - Patch 7: Limit new addresses with the userspace PM to avoid an address ID overflow. A fix for v5.19. - Patch 8: Reset the ADD_ADDR retransmission counter when the timer is reused. A fix for v5.19. - Patch 9: Remove unneeded and confusing READ_ONCE() annotations. A fix for v6.13. - Patches 10-11: Get nstat counters for the current test, not since the creation of the netns. A fix for v6.19. - Patch 12: Fix an uninit-value in mptcp_write_data_fin for a corner case now that only a part of the tcp_out_options struct is reset. A fix for v7.1. - Patches 13-14: Two follow-up patches addressing minor comments discovered after the human review. A fix for v7.3-rc0.
