[PATCH OLK-6.6] mptcp: pm: only decrement add_addr_accepted for MPJ req
by Wang Liang 29 Sep '24

29 Sep '24

From: "Matthieu Baerts (NGI0)" <matttbe(a)kernel.org> stable inclusion from stable-v6.6.48 commit d20bf2c96d7ffd171299b32f562f70e5bf5dc608 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAQOJM CVE: CVE-2024-45009 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 1c1f721375989579e46741f59523e39ec9b2a9bd upstream. Adding the following warning ... WARN_ON_ONCE(msk->pm.add_addr_accepted == 0) ... before decrementing the add_addr_accepted counter helped to find a bug when running the "remove single subflow" subtest from the mptcp_join.sh selftest. Removing a 'subflow' endpoint will first trigger a RM_ADDR, then the subflow closure. Before this patch, and upon the reception of the RM_ADDR, the other peer will then try to decrement this add_addr_accepted. That's not correct because the attached subflows have not been created upon the reception of an ADD_ADDR. A way to solve that is to decrement the counter only if the attached subflow was an MP_JOIN to a remote id that was not 0, and initiated by the host receiving the RM_ADDR.
