[SCTP]: Add RCU synchronization around sctp_localaddr_list
sctp_localaddr_list is modified dynamically via NETDEV_UP and NETDEV_DOWN events, but there is not synchronization between writer (even handler) and readers. As a result, the readers can access an entry that has been freed and crash the sytem. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Acked-by: Sridhar Samdurala <sri@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
