From 0ac1077e3a549bf8d35971613e2be05bdbb41a00 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Tue, 16 Oct 2018 15:52:02 +0800 Subject: sctp: get pr_assoc and pr_stream all status with SCTP_PR_SCTP_ALL instead According to rfc7496 section 4.3 or 4.4: sprstat_policy: This parameter indicates for which PR-SCTP policy the user wants the information. It is an error to use SCTP_PR_SCTP_NONE in sprstat_policy. If SCTP_PR_SCTP_ALL is used, the counters provided are aggregated over all supported policies. We change to dump pr_assoc and pr_stream all status by SCTP_PR_SCTP_ALL instead, and return error for SCTP_PR_SCTP_NONE, as it also said "It is an error to use SCTP_PR_SCTP_NONE in sprstat_policy. " Fixes: 826d253d57b1 ("sctp: add SCTP_PR_ASSOC_STATUS on sctp sockopt") Fixes: d229d48d183f ("sctp: add SCTP_PR_STREAM_STATUS sockopt for prsctp") Reported-by: Ying Xu Signed-off-by: Xin Long Acked-by: Neil Horman Signed-off-by: David S.
