From 7af033010214f2c7cff31147d8970484d46cc14c Mon Sep 17 00:00:00 2001 From: Xin Long Date: Wed, 3 Jul 2019 18:20:20 +0800 Subject: [PATCH] sctp: count data bundling sack chunk for outctrlchunks Now all ctrl chunks are counted for asoc stats.octrlchunks and net SCTP_MIB_OUTCTRLCHUNKS either after queuing up or bundling, other than the chunk maked and bundled in sctp_packet_bundle_sack, which caused 'outctrlchunks' not consistent with 'inctrlchunks' in peer. This issue exists since very beginning, here to fix it by increasing both net SCTP_MIB_OUTCTRLCHUNKS and asoc stats.octrlchunks when sack chunk is maked and bundled in sctp_packet_bundle_sack.
