      bnx2x: prevent GRO false checksum claims · 2c2d06d5
      Yuval Mintz authored 
      This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.

Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.

Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.
This patch remedies this by simply preventing the false claims.

====================
This series adds support for the SRIOV ndo_set_vf callbacks to the mlx4 driver.

Series done against the net-next tree as of commit 0c501345 "batman-adv: fix
global protection fault during soft_iface destruction".

We have successfully tested the series on net-next, except for getting
the VF link info issue I have reported earlier today on netdev, we
see the problem for both ixgbe and mlx4 VFs. Just to make sure get
VF config is working OK with patch #6 - we have run it over 3.8.8 too.

      net/mlx4_en: Add a service task · b6c39bfc
      Amir Vadai authored 
      Add a service task to run tasks that needed to be executed periodically.
Currently the only task is a watchdog to catch NIC clock overflow, to make
timestamping accurate.
Will move the statistics task into this framework in a later patch.

      net/mlx4_en: Support software timestamping · eb0cabbd
      Amir Vadai authored 
      Kernel software timestamping requires that the driver calls skb_tx_timestamp
just before passing the skb to the HW MAC layer. This patch adds this call.

      net/mlx4_en: Add HW timestamping (TS) support · ec693d47
      Amir Vadai authored 
      The patch allows to enable/disable HW timestamping for incoming and/or
outgoing packets. It adds and initializes all structs and callbacks
needed by kernel TS API.
To enable/disable HW timestamping appropriate ioctl should be used.
Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are
supported.
When enabling TS on receive flow - VLAN stripping will be disabled.
Also were made all relevant changes in RX/TX flows to consider TS request
and plant HW timestamps into relevant structures.
mlx4_ib was fixed to compile with new mlx4_cq_alloc() signature.

====================
Here is one last(?) big wireless bits pull request before the merge window...

Regarding the mac80211 bits, Johannes says:

"Here's another big pull request for the -next stream. This one has a ton
of driver updates, which hopefully addresses all drivers, but maybe you
have more new drivers than I have in my tree? Not entirely sure, let me
know if this is the case and then I can merge wireless-next.

I'm including a large number of small changes, see the shortlog. The two
bigger things are making VHT compatible with not using channel contexts
(from Karl) and the stop-while-suspended fixes I developed together with
Stanislaw."

...and...

"This time I have a relatively large number of fixes and small
improvements, the most important one being Bob's RCU fix. The two big
things are Felix's work on rate scaling tables (with a big thanks to
Karl too) and my own work on CSA handling to finally properly handle HT
(and some VHT.)"

As for the iwlwifi bits, Johannes says:

"The biggest work here is Bluetooth coexistence and power saving. Other
than that, I have a few small fixes that weren't really needed for 3.9
and a new PCI ID."

About the NFC bits, Samuel says:

"With this one we have:

- A major pn533 update. The pn533 framing support has been changed in order to
  easily support all pn533 derivatives. For example we now support the ACR122
  USB dongle.

- An NFC MEI physical layer code factorization through the mei_phy NFC API.
  Both the microread and the pn544 drivers now use it.

- LLCP aggregation support. This allows NFC p2p devices to send aggregated
  frames containing all sort of LLCP frames except SYMM and aggregation
  frames.

- More LLCP socket options for getting the remote device link parameters.

- Fixes for the LLCP socket option code added with the first pull request for
  3.10.

- Some support for LLCP corner cases like 0 length SDUs and general DISC
  (tagged with a 0,0 dsap ssap couple) handling.

- RFKILL support for NFC."

For the b43 bits, Rafał says:

"Let me remind the changes for b43:
> Changes include:
> 1) Minor improvements for HT-PHY code (BCM4331)
> 2) Code cleaning for HT-PHY and N-PHY"

Concerning the bluetooth bits, Gustavo says:

"A set of changes intended for 3.10. The biggest changes here are from David
Herrmann, he rewrote most of the HIDP layer making it more reliable. Marcel
added a driver setup stage for device that need special handling on their
early initialization. Other than that we have the usual clean ups, bugfixes
and small improvements."

Along with all that, there is the usual collection of random/various
updates to ath9k, mwifiex, brcmfmac, brcmsmac, rt2x00, and wil6210.

I also included a pull of the wireless tree to resolve a merge conflict.

Please let me know if there are problems!

      netlink: fix compilation after memory mapped patches · 1bf9310a
      Nicolas Dichtel authored 
      Depending of the kernel configuration (CONFIG_UIDGID_STRICT_TYPE_CHECKS), we can
get the following errors:

net/netlink/af_netlink.c: In function ‘netlink_queue_mmaped_skb’:
net/netlink/af_netlink.c:663:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kuid_t’
net/netlink/af_netlink.c:664:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kgid_t’

net/netlink/af_netlink.c:694:14: error: incompatible types when assigning to type ‘__u32’ from type ‘kgid_t’

We must use the helpers to get the uid and gid, and also take care of user_ns.

Fix suggested by Eric W. Biederman <ebiederm@xmission.com>.
