2014-05-07net: clean up snmp stats codeWANG Cong
commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%) reduced snmp array size to 1, so technically it doesn't have to be an array any more. What's more, after the following commit: commit 933393f58fef9963eac61db8093689544e29a600 Date: Thu Dec 22 11:58:51 2011 -0600 percpu: Remove irqsafe_cpu_xxx variants 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. probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after almost 3 years, no one complains. So, just convert the array to a single pointer and remove snmp_mib_init() and snmp_mib_free() as well.

2014-05-07net: ip: push gso skb forwarding handling down the stackFlorian Westphal
Doing the segmentation in the forward path has one major drawback: When using virtio, we may process gso udp packets coming from host network stack. In that case, netfilter POSTROUTING will see one packet with udp header followed by multiple ip fragments. Delay the segmentation and do it after POSTROUTING invocation to avoid this.

2014-05-07net: ipv6: send pkttoobig immediately if orig frag size > mtuFlorian Westphal
If conntrack defragments incoming ipv6 frags it stores largest original frag size in ip6cb and sets ->local_df. We must thus first test the largest original frag size vs. mtu, and not vice versa. Without this patch PKTTOOBIG is still generated in ip6_fragment() later in the stack, but 1) IPSTATS_MIB_INTOOBIGERRORS won't increment 2) packet did (needlessly) traverse netfilter postrouting hook.

2014-05-07net: ipv4: ip_forward: fix inverted local_df testFlorian Westphal
local_df means 'ignore DF bit if set', so if its set we're allowed to perform ip fragmentation. This wasn't noticed earlier because the output path also drops such skbs (and emits needed icmp error) and because netfilter ip defrag did not set local_df until couple of days ago. Only difference is that DF-packets-larger-than MTU now discarded earlier (f.e. we avoid pointless netfilter postrouting trip). While at it, drop the repeated test ip_exceeds_mtu, checking it once is enough...

2014-05-06mac80211: fix CSA tx queue stoppingMichal Kazior
It was possible for tx queues to be stuck stopped if AP CSA finalization failed. In that case neither stop_ap nor do_stop woke the queues up. This means it was impossible to perform tx at all until driver was reloaded or a successful CSA was performed later. It was possible to solve this in a simpler manner however this is more robust and future proof (having multi-vif CSA in mind). New sdata->csa_block_tx is introduced to keep track of which interfaces requested tx to be blocked for CSA. This is required because mac80211 stops all tx queues for that purpose. This means queues must be awoken only when last tx-blocking CSA interface is finished. It is still possible to have tx queues stopped after CSA failure but as soon as offending interfaces are stopped from userspace (stop_ap or ifdown) tx queues are woken up properly.

This patch fixes ordering of rtnl notifications during unregister_netdevice by moving RTM_DELLINK notification to until after ndo_uninit. The problem was seen with unregistering bond netdevices. bond ndo_uninit callback generates a few RTM_NEWLINK notifications for NETDEV_CHANGEADDR and NETDEV_FEAT_CHANGE. This is seen mostly when the bond is deleted with slaves still enslaved to the bond. During unregister netdevice (rollback_registered_many to be specific) bond ndo_uninit is called after RTM_DELLINK notification goes out. This results in userspace seeing RTM_DELLINK followed by a couple of RTM_NEWLINK's. In userspace problem was seen with libnl. libnl cache deletes the bond when it sees RTM_DELLINK and re-adds the bond with the following RTM_NEWLINK. Resulting in a stale bond entry in libnl cache when the kernel has already deleted the bond. This patch has been tested for bond, bridges and vlan devices.
