From Eric Dumazet. 7) Fix non-root process spoofing in netlink, from Pablo Neira Ayuso. 8) CWND reduction in TCP is done incorrectly during non-SACK recovery, fix from Yuchung Cheng. 9) Revert netpoll change, and fix what was actually a driver specific problem. From Amerigo Wang. This should cure bootup hangs with netconsole some people reported. 10) Fix xen-netfront invoking __skb_fill_page_desc() with a NULL page pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A usbnet device can share a multifunction device with a storage device. If the storage device is autoresumed the usbnet devices also needs to be autoresumed. Allocating memory with GFP_KERNEL can deadlock in this case.

| * e1000e: DoS while TSO enabled caused by link partner with small MSSBruce Allan2012-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a low enough MSS on the link partner and TSO enabled locally, the networking stack can periodically send a very large (e.g. 64KB) TCP message for which the driver will attempt to use more Tx descriptors than are available by default in the Tx ring. This is due to a workaround in the code that imposes a limit of only 4 MSS-sized segments per descriptor which appears to be a carry-over from the older e1000 driver and may be applicable only to some older PCI or PCIx parts which are not supported in e1000e. When the driver gets a message that is too large to fit across the configured number of Tx descriptors, it stops the upper stack from queueing any more and gets stuck in this state. After a timeout, the upper stack assumes the adapter is hung and calls the driver to reset it. Remove the unnecessary limitation of using up to only 4 MSS-sized segments per Tx descriptor, and put in a hard failure test to catch when attempting to check for message sizes larger than would fit in the whole Tx ring. Refactor the remaining logic that limits the size of data per Tx descriptor from a seemingly arbitrary 8KB to a limit based on the dynamic size of the Tx packet buffer as described in the hardware specification. Also, fix the logic in the check for space in the Tx ring for the next largest possible packet after the current one has been successfully queued for transmit, and use the appropriate defines for default ring sizes in e1000_probe instead of magic values. This issue goes back to the introduction of e1000e in 2.6.24 when it was split off from e1000.

| * xen-netfront: use __pskb_pull_tail to ensure linear area is big enough on RXIan Campbell2012-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm slightly concerned by the "only in exceptional circumstances" comment on __pskb_pull_tail but the structure of an skb just created by netfront shouldn't hit any of the especially slow cases. This approach still does slightly more work than the old way, since if we pull up the entire first frag we now have to shuffle everything down where before we just received into the right place in the first place.

The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.
