sctp: Push struct net down into all of the state machine functions (24cb81a6) · Commits · 戴 / test

There are a handle of state machine functions primarily those dealing with processing INIT packets where there is neither a valid endpoint nor a valid assoication from which to derive a struct net. Therefore add struct net * to the parameter list of sctp_state_fn_t and update all of the state machine functions. Signed-off-by:
