The atl1c driver uses the legacy PCI power management, so it has to do some PCI-specific things in its ->suspend() and ->resume() callbacks and they are not done correctly. Convert atl1c to the new PCI power management framework and make it let the PCI subsystem handle all of the PCI-specific aspects of device handling during system power transitions.

This function has three bugs: 1) The offset should be valid most of the time, this is just a sanity check, therefore we should use "likely" not "unlikely" 2) This is the only place where we can check for arithmetic overflow of the pointer plus the length. 3) The existing range checks are off by one, the valid range is skb->head to skb_tail_pointer(), inclusive.

When deploying SFQ/IFB here at work, I found the allot management was pretty wrong in sfq, even changing allot from short to int... We should init allot for each new flow, not using a previous value found in slot. Before patch, I saw bursts of several packets per flow, apparently denying the default "quantum 1514" limit I had on my SFQ class. class sfq 11:1 parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 7p requeues 0 allot 11546 class sfq 11:46 parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 1p requeues 0 allot -23873 class sfq 11:78 parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 5p requeues 0 allot 11393 After patch, better fairness among each flow, allot limit being respected, allot is positive : class sfq 11:e parent 11: (dropped 0, overlimits 0 requeues 86) backlog 0b 3p requeues 86 allot 596 class sfq 11:94 parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 3p requeues 0 allot 1468 class sfq 11:a4 parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 4p requeues 0 allot 650 class sfq 11:bb parent 11: (dropped 0, overlimits 0 requeues 0) backlog 0b 3p requeues 0 allot 596 Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

bond_na_send() attempts to insert a VLAN tag in between building and sending packets of the respective formats. If the slave does not implement hardware VLAN tag insertion then vlan_put_tag() will mangle the network-layer header because the Ethernet header is not present at this point (unlike in bond_arp_send()). Fix this by adding the tag out-of-line and relying on dev_hard_start_xmit() to insert it inline if necessary.

A bond may have a mixture of slave devices with and without hardware VLAN tag insertion capability. Therefore it always claims this capability and performs software VLAN tag insertion if the slave does not. Since commit 7b9c6090, this has also been done by dev_hard_start_xmit(). The result is that VLAN- tagged skbs are now double-tagged when transmitted through slave devices without hardware VLAN tag insertion! Remove the now-redundant logic from bond_dev_queue_xmit().

The first big packets sent to a "low-MTU" client correctly triggers the creation of a temporary route containing the reduced MTU. But after the temporary route has expired, new ICMP6 "packet too big" will be sent, rt6_pmtu_discovery will find the previous EXPIRED route check that its mtu isn't bigger then in icmp packet and do nothing before the temporary route will not deleted by gc. I make the simple experiment: while :; do time ( dd if=/dev/zero bs=10K count=1 | ssh hostname dd of=/dev/null ) || break; done The "time" reports real 0m0.197s if a temporary route isn't expired, but it reports real 0m52.837s (!!!!) immediately after a temporare route has expired.

On suspend, there might be usb wireless drivers which wrongly trigger the warning in ieee80211_work_work. If an usb driver doesn't have a suspend hook, the usb stack will disconnect the device. On disconnect, a mac80211 driver calls ieee80211_unregister_hw, which calls dev_close, which calls ieee80211_stop, and in the end calls ieee80211_work_purge-> ieee80211_work_work. The problem is that this call to ieee80211_work_purge comes after mac80211 is suspended, triggering the warning even when we don't have work queued in work_list (the expected case when already suspended), because it always calls ieee80211_work_work. So, just call ieee80211_work_work in ieee80211_work_purge if we really have to abort work.
