In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: only decrement add_addr_accepted for MPJ req
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.
