From 999417549c16dd0e3a382aa9f6ae61688db03181 Mon Sep 17 00:00:00 2001 From: Jon Paul Maloy Date: Fri, 11 Jul 2014 08:45:27 -0400 Subject: [PATCH] tipc: clear 'next'-pointer of message fragments before reassembly If the 'next' pointer of the last fragment buffer in a message is not zeroed before reassembly, we risk ending up with a corrupt message, since the reassembly function itself isn't doing this. Currently, when a buffer is retrieved from the deferred queue of the broadcast link, the next pointer is not cleared, with the result as described above. This commit corrects this, and thereby fixes a bug that may occur when long broadcast messages are transmitted across dual interfaces. The bug has been present since 40ba3cdf542a469aaa9083fa041656e59b109b90 ("tipc: message reassembly using fragment chain") This commit should be applied to both net and net-next.
