From eeb148d20819b94d22990a162f751f4df12a660b Mon Sep 17 00:00:00 2001 From: Xin Long Date: Mon, 12 Aug 2019 20:49:12 +0800 Subject: [PATCH] sctp: fix the transport error_count check [ Upstream commit a1794de8b92ea6bc2037f445b296814ac826693e ] As the annotation says in sctp_do_8_2_transport_strike(): "If the transport error count is greater than the pf_retrans threshold, and less than pathmaxrtx ..." It should be transport->error_count checked with pathmaxrxt, instead of asoc->pf_retrans.
