2014-02-14Merge tag 'edac_for_3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bpLinus Torvalds
Pull EDAC fixes from Borislav Petkov: "Fix polling timeout setting through sysfs. You're surely wondering why the patches are not based on an rc. Well, Andrew sent you 79040cad3f82 ("drivers/edac/edac_mc_sysfs.c: poll timeout cannot be zero sent you") already (it got in in -rc2) but it is not enough as a fix because for one, setting too low polling intervals (< 1sec) don't make any sense and cause unnecessary polling load on the system. Then, even if we set some interval, we explode with [ 4143.094342] WARNING: CPU: 1 PID: 0 at kernel/workqueue.c:1393 __queue_work+0x1d7/0x340() because the workqueue setup path is used also for the timeout period resetting and we're doing INIT_DELAYED_WORK() on an already active workqueue. Which is total bollocks. So this is taken care of by the second patch. I've CCed stable for those two" * tag 'edac_for_3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp: EDAC: Correct workqueue setup path EDAC: Poll timeout cannot be zero, p2

Tommi noticed a 'funny' lock class name: "%s#5" from a lock acquired in process_one_work(). Maybe #fmt plus #args could be used as the lock_name to give some more information for some fmt string like the above. __builtin_constant_p() check is removed (as there seems no good way to check all the variables in args list). However, by removing the check, it only adds two additional "s for those constants.

Part of the timestamping functionality of the dp83640 is set up in the probe and with that lost, enabling timestamping will cause a PHY lockup, requiring a hard reset / power cycle to recover.

2014-02-13vhost: fix a theoretical race in device cleanupMichael S. Tsirkin
vhost_zerocopy_callback accesses VQ right after it drops a ubuf reference. In theory, this could race with device removal which waits on the ubuf kref, and crash on use after free. Do all accesses within rcu read side critical section, and synchronize on release. Since callbacks are always invoked from bh, synchronize_rcu_bh seems enough and will help release complete a bit faster. Signed-off-by: Michael S.

2014-02-13vhost: fix ref cnt checking deadlockMichael S. Tsirkin
vhost checked the counter within the refcnt before decrementing. It really wanted to know that it is the one that has the last reference, as a way to batch freeing resources a bit more efficiently. Note: we only let refcount go to 0 on device release. This works well but we now access the ref counter twice so there's a race: all users might see a high count and decide to defer freeing resources. In the end no one initiates freeing resources until the last reference is gone (which is on VM shotdown so might happen after a looooong time). Let's do what we probably should have done straight away: switch from kref to plain atomic, documenting the semantics, return the refcount value atomically after decrement, then use that to avoid the deadlock.

Packets which have L2 address different from ours should be already filtered before entering into ip_forward(). Perform that check at the beginning to avoid processing such packets. Signed-off-by: Denis Kirjanov <kda@linux-powerpc.org> Signed-off-by: David S. Miller <davem@davemloft.net>
