sctp: use SCTP_FUTURE_ASSOC and add SCTP_CURRENT_ASSOC for SCTP_AUTH_DEACTIVATE_KEY sockopt
Check with SCTP_ALL_ASSOC instead in sctp_setsockopt_deactivate_key. SCTP_CURRENT_ASSOC is supported for SCTP_AUTH_DEACTIVATE_KEY in this patch. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
