This adds an additional queuing strategy, called pfifo_head_drop, to remove the oldest skb in the case of an overflow within the queue - the head element - instead of the last skb (tail). To remove the oldest skb in congested situations is useful for sensor network environments where newer packets reflect the superior information. Reviewed-by:

I'm not sure about rcu stuff near kmem cache destruction: * checks for non-empty hashes look bogus, they're done _before_ rcu_berrier() * unregistering netns ops is done before kmem_cache destoy (as it should), and unregistering involves rcu barriers by itself So it looks nothing should be done.

The convention for API functions in kernel is to return errno value; bond_open would return -1 if alb setup failed. The only reason that could happen is if kmalloc() failed. Signed-off-by:

Call ixgbe_copy_dcb_cfg() earlier in the ixgbe_dcbnl_set_all() so that we can learn if this is going to fail as early as possible. Previously, ixgbe_down or ixgbe_close were being called before this check and the IXGBE_RESETTING bit was being set and cleared. Worse if this failed the corresponding ixgbe_up/ndo_open would not called. Signed-off-by:

netdev_open() will return without cleaning up net device or hardware state if firmware loading fails. This results in a BUG() on a second attempt to bring the interface up, reported in <http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even worse effects if the driver is removed afterwards. Call netdev_close() to clean up on failure. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=15091Signed-off-by:

I got below kernel oops when I try to bring down the network interface if ftrace is enabled. The root cause is drv_ampdu_action() is passed with a NULL ssn pointer in the BA session tear down case. We need to check and avoid dereferencing it in trace entry assignment.

The commit 0b5ccb2e(title:ipv6: reassembly: use seperate reassembly queues for conntrack and local delivery) has broken the saddr&&daddr member of nf_ct_frag6_queue when creating new queue. And then hash value generated by nf_hashfn() was not equal with that generated by fq_find(). So, a new received fragment can't be inserted to right queue. The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure. Signed-off-by:
