* caif: Bugfix list_del_rcu race in cfmuxl_ctrlcmd.sjur.brandeland@stericsson.com2012-02-021-9/+3
| | | | | | | | | | | | | | | Always use cfmuxl_remove_uplayer when removing a up-layer. cfmuxl_ctrlcmd() can be called independently and in parallel with cfmuxl_remove_uplayer(). The race between them could cause list_del_rcu to be called on a node which has been already taken out from the list. That lead to a (rare) crash on accessing poisoned node->prev inside list_del_rcu. This fix ensures that deletion are done holding the same lock.

* rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTERStephen Hemminger2011-08-021-3/+3
| | | | | | | | | | | | | | | | | | | | When assigning a NULL value to an RCU protected pointer, no barrier is needed. The rcu_assign_pointer, used to handle that but will soon change to not handle the special case. Convert all rcu_assign_pointer of NULL value. //smpl @@ expression P; @@ - rcu_assign_pointer(P, NULL) + RCU_INIT_POINTER(P, NULL) // </smpl> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: Paul E.

* caif: Bugfix - XOFF removed channel from caif-muxsjur.brandeland@stericsson.com2011-06-161-1/+1
| | | | | | | | | XOFF was mixed up with DOWN indication, causing causing CAIF channel to be removed from mux and all incoming traffic to be lost after receiving flow-off. Fix this by replacing FLOW_OFF with DOWN notification. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S. Miller <davem@conan.davemloft.net>
* caif: Fixes freeze on Link layer removal.sjur.brandeland@stericsson.com2011-05-221-11/+38
| | | | | | | | | | | | | | | | | | | | CAIF Socket layer - caif_socket.c: - Plug mem-leak at reconnect. - Always call disconnect to cleanup CAIF stack. - Disconnect will always report success. CAIF configuration layer - cfcnfg.c - Disconnect must dismantle the caif stack correctly - Protect against faulty removals (check on id zero) CAIF mux layer - cfmuxl.c - When inserting new service layer in the MUX remove any old entries with the same ID. - When removing CAIF Link layer, remove the associated service layers before notifying service layers.

| | | | | | | | | Replace spin_lock with rcu_read_lock when accessing lists to layers and cache.
