caif: Bugfix double kfree_skb upon xmit failure

2012-02-02T19:35:12Z

SKB is freed twice upon send error. The Network stack consumes SKB even when it returns error code. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Bugfix list_del_rcu race in cfmuxl_ctrlcmd.

2012-02-02T19:35:12Z

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. Reported-by: Dmitry Tarnyagin Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

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: Remove bad WARN_ON in caif_dev

2012-01-17T15:46:55Z

Remove WARN_ON and bad handling of SKB without destructor callback in caif_flow_cb. SKB without destructor cannot be handled as an error case. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Fix typo in Vendor/Product-ID for CAIF modems

2012-01-17T15:46:55Z

Fix typo for the Vendor/Product Id for ST-Ericsson CAIF modems. Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson), product-id 0x230f (NCM). Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

* 'for-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: Remove irqsafe_cpu_xxx variants Fix up conflict in arch/x86/include/asm/percpu.h due to clash with cebef5beed3d ("x86: Fix and improve percpu_cmpxchg{8,16}b_double()") which edited the (now removed) irqsafe_cpu_cmpxchg*_double code.

percpu: Remove irqsafe_cpu_xxx variants

2011-12-22T18:40:20Z

We simply say that regular this_cpu use must be safe regardless of preemption and interrupt state. That has no material change for x86 and s390 implementations of this_cpu operations. However, arches that do not provide their own implementation for this_cpu operations will now get code generated that disables interrupts instead of preemption. -tj: This is part of on-going percpu API cleanup.

net: fix assignment of 0/1 to bool variables.

caif: Replace BUG_ON with WARN_ON.

2011-12-06T22:21:47Z

BUG_ON is too strict in a number of circumstances, use WARN_ON instead. Protocol errors should not halt the system. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller
