From 80df2704a375bb4b3c9c5cce9c00052361b16d61 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Mon, 28 Jan 2019 15:08:23 +0800 Subject: sctp: introduce SCTP_FUTURE/CURRENT/ALL_ASSOC This patch is to add 3 constants SCTP_FUTURE_ASSOC, SCTP_CURRENT_ASSOC and SCTP_ALL_ASSOC for reserved assoc_ids, as defined in rfc6458#section-7.2. And add the process for them when doing lookup and inserting in sctp_id2assoc and sctp_assoc_set_id. Signed-off-by: Xin Long Signed-off-by: David S.
