net caif: Register properly as a pernet subsystem.

2012-01-28T02:06:03Z

caif is a subsystem and as such it needs to register with register_pernet_subsys instead of register_pernet_device. Among other problems using register_pernet_device was resulting in net_generic being called before the caif_net structure was allocated. Which has been causing net_generic to fail with either BUG_ON's or by return NULL pointers. A more ugly problem that could be caused is packets in flight why the subsystem is shutting down. To remove confusion also remove the cruft cause by inappropriately trying to fix this bug. With the aid of the previous patch I have tested this patch and confirmed that using register_pernet_subsys makes the failure go away as it should. Signed-off-by: Eric W.

caif: add error handling for allocation

2011-10-03T17:45:49Z

The allocation of "phyinfo" wasn't checked, and also the allocation wasn't freed on error paths. Sjur Brændeland pointed out as well that "phy_driver" should be freed on the error path too. Signed-off-by: Dan Carpenter Acked-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Remove OOM messages, use kzalloc

2011-08-28T21:16:13Z

Remove per site OOM messages because they duplicate the generic mm subsystem OOM message. Use kzalloc instead of kmalloc/memset when next to the OOM message removals.

caif: Fixes freeze on Link layer removal.

2011-05-23T00:11:47Z

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.

caif: Handle dev_queue_xmit errors.

2011-05-15T21:45:56Z

Do proper handling of dev_queue_xmit errors in order to avoid double free of skb and leaks in error conditions. In cfctrl pending requests are removed when CAIF Link layer goes down. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: prepare support for namespaces

2011-05-15T21:45:55Z

Use struct net to reference CAIF configuration object instead of static variables. Refactor functions caif_connect_client, caif_disconnect_client and squach files cfcnfg.c and caif_config_utils. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Add ref-count to framing layer

2011-05-15T21:45:55Z

Introduce Per-cpu reference for lower part of CAIF Stack. Before freeing payload is disabled, synchronize_rcu() is called, and then ref-count verified to be zero. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Use RCU and lists in cfcnfg.c for managing caif link layers

2011-05-15T21:45:54Z

RCU lists are used for handling the link layers instead of array. When generating CAIF phy-id, ifindex is used as base. Legal range is 1-6. Introduced set_phy_state() for managing CAIF Link layer state. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller
