2016-03-30bpf: make padding in bpf_tunnel_key explicitDaniel Borkmann
Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl and tunnel_label members explicit. No issue has been observed, and gcc/llvm does padding for the old struct already, where tunnel_label was not yet present, so the current code works, but since it's part of uapi, make sure we don't introduce holes in structs. Therefore, add tunnel_ext that we can use generically in future (f.e. to flag OAM messages for backends, etc). Also add the offset to the compat tests to be sure should some compilers not padd the tail of the old version of bpf_tunnel_key.

This patch should fix the issues seen with a recent fix to prevent tunnel-in-tunnel frames from being generated with GRO. The fix itself is correct for now as long as we do not add any devices that support NETIF_F_GSO_GRE_CSUM. When such a device is added it could have the potential to mess things up due to the fact that the outer transport header points to the outer UDP header and not the GRE header as would be expected.

This goes all the way back to the original KMS commit aeons ago commit f453ba0460742ad027ae0c4c7d61e62817b3e7ef Author: Dave Airlie <airlied@redhat.com> Date: Fri Nov 7 14:05:41 2008 -0800 DRM: add mode setting support But it seems to be completely unused. Only i915 and nouveau even register these properties, and the corresponding DDX don't even look at them. Also the sysfs files are read-only, so not useful to configure anything. I suspect that this was added with the goal to have read-only access to all properties in sysfs, but we never followed through on that. Also, that should be done in a more generic fashion. Since it would be real work to fix up the locking (with atomic we're now chasing pointers when reading properties) and it seems unused lets just nuke this all. It's easier. Of course we'll keep the properties themselves, those are still exposed through the KMS ioctls.

2016-03-30drm/i915: Fix races on fbdevLukas Wunner
The ->lastclose callback invokes intel_fbdev_restore_mode() and has been witnessed to run before intel_fbdev_initial_config_async() has finished. We might likewise receive hotplug events before we've had a chance to fully set up the fbdev. Fix by waiting for the asynchronous thread to finish. v2: An async_synchronize_full() was also added to intel_fbdev_set_suspend() in v1 which turned out to be entirely gratuitous. It caused a deadlock on suspend (discovered by CI, thanks to Damien Lespiau and Tomi Sarvela for CI support) and was unnecessary since a device is never suspended until its ->probe callback (and all asynchronous tasks it scheduled) have finished. See dpm_prepare(), which calls wait_for_device_probe(), which calls async_synchronize_full().

2016-03-29ixgbevf: call ndo_stop() instead of dev_close() when running offline selftestStefan Assmann
Calling dev_close() causes IFF_UP to be cleared which will remove the interfaces routes and some addresses. That's probably not what the user intended when running the offline selftest. Besides this does not happen if the interface is brought down before the test, so the current behaviour is inconsistent. Instead call the net_device_ops ndo_stop function directly and avoid touching IFF_UP at all.

2016-03-29ixgbe: Fix ATR so that it correctly handles IPv6 extension headersAlexander Duyck
The ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through. However this isn't the case as it is possible for a frame to arrive that is TCP but sent through something like a raw socket. As a result the driver was setting up bad filters in which tcp_hdr was really pointing to the network header so the data was all invalid. In order to correct this I have added a bit of parsing logic that will determine the TCP header location based off of the network header and either the offset in the case of the IPv4 header, or a walk through the IPv6 extension headers until it encounters the header that indicates IPPROTO_TCP. In addition I have added checks to verify that the lowest protocol provided is recognized as IPv4 or IPv6 to help mitigate raw sockets using ETH_P_ALL from having ATR applied to them.

2016-03-29ixgbe: Store VXLAN port number in network orderAlexander Duyck
The VXLAN port number should be stored in network order instead of in host order as it is accessed from the hot-path in ATR. This way we can avoid having to do any byte swaps in order to validate the port number. I moved the vxlan_port value into a hole in the read-mostly region of the adapter struct. This way it should be in a warm cache-line instead of in some isolated region in memory when it needs to be accessed. In addition I went through and stripped a bunch of unneeded ifdef flags since having an extra variable present doesn't really hurt anything and makes the code easier to read. I also went through and dropped the NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides no value as the flag is not evaluated in the Rx path.

2016-03-29ixgbe: Fix for RAR0 not being set to default MAC addrTushar Dave
commit c9f53e63c208 ("ixgbe: Refactor MAC address configuration code") introduced code that doesn't set HW register RAR0 to default mac address but FF:FF:FF:FF:FF:FF. Due to this, ixgbe HW discards all incoming packets that doesn't have destination mac address equals to FF:FF:FF:FF:FF:FF. This commit sets RAR0 correctly to default HW mac address.
