From 2cb2b3fb20a2a9448285628c6da97a283a5a73b4 Mon Sep 17 00:00:00 2001 From: Jamie Bainbridge Date: Mon, 4 Apr 2022 09:47:48 +1000 Subject: [PATCH] sctp: count singleton chunks in assoc user stats [ Upstream commit e3d37210df5c41c51147a2d5d465de1a4d77be7a ] Singleton chunks (INIT, HEARTBEAT PMTU probes, and SHUTDOWN- COMPLETE) are not counted in SCTP_GET_ASOC_STATS "sas_octrlchunks" counter available to the assoc owner. These are all control chunks so they should be counted as such. Add counting of singleton chunks so they are properly accounted for.
