Eric Dumazet 70f5ab8e46 netlink: hold nlk->cb_mutex longer in __netlink_dump_start() ... [ Upstream commit b559027006 ] __netlink_dump_start() releases nlk->cb_mutex right before calling netlink_dump() which grabs it again. This seems dangerous, even if KASAN did not bother yet. Add a @lock_taken parameter to netlink_dump() to let it grab the mutex if called from netlink_recvmsg() only.
