From 8cee83dd29dea4e7d27fda3b170381059f628868 Mon Sep 17 00:00:00 2001 From: Parthasarathy Bhuvaragan Date: Thu, 21 Apr 2016 15:51:13 +0200 Subject: [PATCH] tipc: fix stale links after re-enabling bearer Commit 42b18f605fea ("tipc: refactor function tipc_link_timeout()"), introduced a bug which prevents sending of probe messages during link synchronization phase. This leads to hanging links, if the bearer is disabled/enabled after links are up. In this commit, we send the probe messages correctly.
