Tuong Lien 9798278260 tipc: fix NULL pointer dereference in tipc_disc_rcv() ... When a bearer is enabled, we create a 'tipc_discoverer' object to store the bearer related data along with a timer and a preformatted discovery message buffer for later probing... However, this is only carried after the bearer was set 'up', that left a race condition resulting in kernel panic. It occurs when a discovery message from a peer node is received and processed in bottom half (since the bearer is 'up' already) just before the discoverer object is created but is now accessed in order to update the preformatted buffer (with a new trial address, ...) so leads to the NULL pointer dereference. We solve the problem by simply moving the bearer 'up' setting to later, so make sure everything is ready prior to any message receiving.
