Subject: [TIPC] BUG: unable to handle kernel NULL pointer dereference at
00000014
Greetings,
I got the below dmesg and the first bad commit is
commit 0fb0040ed697d2b0fbd484042cdebbe76d29a840
Author: Ying Xue <ying.xue@...driver.com>
Date: Mon May 6 23:57:18 2013 -0400
tipc: convert configuration server to use new server facility
As the new socket-based TIPC server infrastructure has been
introduced, we can now convert the configuration server to use
it. Then we can take future steps to simplify the configuration
server locking policy.
Some minor reordering of initialization is done, due to the
dependency on having tipc_socket_init completed.
