Subject: [PATCH] mptcp: pm: avoid possible UaF when selecting endp
select_local_address() and select_signal_address() both select an
endpoint entry from the list inside an RCU protected section, but return
a reference to it, to be read later on. If the entry is dereferenced
after the RCU unlock, reading info could cause a Use-after-Free.
A simple solution is to copy the required info while inside the RCU
protected section to avoid any risk of UaF later. The address ID might
need to be modified later to handle the ID0 case later, so a copy seems
OK to deal with.

[ Conflicts in pm_netlink.c, because quite a bit of new code has been
added around since commit 86e39e04482b ("mptcp: keep track of local
endpoint still available for each msk"), and commit 2843ff6f36db
("mptcp: remote addresses fullmesh"). But the issue is still there.
The conflicts have been resolved using the same way: by adding a new
parameter to select_local_address() and select_signal_address(), and
use it instead of the pointer they were previously returning. The code
is simpler in this version, this conflict resolution looks safe. ]
