2013-09-03bonding: remove bond_vlan_used()Veaceslav Falico
We're using it currently to verify if we have vlans before getting the tag from the skb we're about to send. It's useless because the vlan_get_tag() verifies if the skb has the tag (and returns an error if not), and we can receive tagged skbs only if we *already* have vlans. Plus, the current RCUed implementation is kind of useless anyway - the we can remove the last vlan in the moment we return from the function. So remove the only usage of it and the whole function.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== Please accept this batch of updates intended for the 3.12 stream. For the mac80211 bits, Johannes says this: "This time I have various improvements all over the place: IBSS, mesh, testmode, AP client powersave handling, one of the rare rfkill patches and some code cleanup." Also for mac80211: "And I also have some more changes for -next, just a few small fixes and improvements, nothing really stands out." And for iwlwifi: "This time I have some powersave work (notably uAPSD support), CQM offloads, support for a new firmware API and various code cleanups." Regarding the Bluetooth bits, Gustavo says: "Patches to 3.12, here we have: * implementation of a proper tty_port for RFCOMM devices, this fixes some issues people were seeing lately in the kernel. * Add voice_setting option for SCO, it is used for SCO Codec selection * bugfixes, small improvements and clean ups" For the NFC bits, Samuel says: "With this one we have: - A few pn533 improvements and minor fixes. Testing our pn533 driver against Google's NCI stack triggered a few issues that we fixed now. We also added Tx fragmentation support to this driver. - More NFC secure element handling. We added a GET_SE netlink command for getting all the discovered secure elements, and we defined 2 additional secure element netlink event (transaction and connectivity). We also fixed a couple of typos and copy-paste bugs from the secure element handling code. - Firmware download support for the pn544 driver. This chipset can enter a special mode where it's waiting for firmware blobs to replace the already flashed one. We now support that mode." With repect to the ath tree, Kalle says: "New features in ath10k are rx/tx checsumming in hw and survey scan implemented by Michal. Also he made fixes to different areas of the driver, most notable being fixing the case when using two streams and reducing the number of interface combinations to avoid firmware crashes. Bartosz did a clean related to how we handle SoC power save in PCI layer. For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent crashes." I also pulled the wireless tree into wireless-next to support a request from Johannes. On top of all that, there are the usual sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k, and rt2x00 drivers all get some attention, as does the bcma bus and a few other random bits here and there. ==================== Signed-off-by: David S.

2013-09-03net: neighbour: Remove CONFIG_ARPDTim Gardner
This config option is superfluous in that it only guards a call to neigh_app_ns(). Enabling CONFIG_ARPD by default has no change in behavior. There will now be call to __neigh_notify() for each ARP resolution, which has no impact unless there is a user space daemon waiting to receive the notification, i.e., the case for which CONFIG_ARPD was designed anyways.

2013-09-03virtio-net: Set RXCSUM feature if GUEST_CSUM is availableThomas Huth
If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest does not have to calculate the checksums on all received packets. This is pretty much the same feature as RX checksum offloading on real network cards, so the virtio-net driver should report this by setting the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she can see whether the virtio-net interface has to calculate RX checksums or not.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: "A lot of activities on the cgroup front. Most changes aren't visible to userland at all at this point and are laying foundation for the planned unified hierarchy. - The biggest change is decoupling the lifetime management of css (cgroup_subsys_state) from that of cgroup's. Because controllers (cpu, memory, block and so on) will need to be dynamically enabled and disabled, css which is the association point between a cgroup and a controller may come and go dynamically across the lifetime of a cgroup. Till now, css's were created when the associated cgroup was created and stayed till the cgroup got destroyed. Assumptions around this tight coupling permeated through cgroup core and controllers. These assumptions are gradually removed, which consists bulk of patches, and css destruction path is completely decoupled from cgroup destruction path. Note that decoupling of creation path is relatively easy on top of these changes and the patchset is pending for the next window. - cgroup has its own event mechanism cgroup.event_control, which is only used by memcg. It is overly complex trying to achieve high flexibility whose benefits seem dubious at best.

2013-09-03Merge branch 'addr_assign_type'David S. Miller
Bjørn Mork says: ==================== net: set addr_assign_type when inheriting a dev_addr Copying the dev_addr from a parent device is an operation common to a number of drivers. The addr_assign_type should be updated accordingly, either by reusing the value from the source device or explicitly indicating that the address is stolen by setting addr_assign_type to NET_ADDR_STOLEN. This patch set adds a helper copying both the dev_addr and the addr_assign_type, and use this helper in drivers which don't currently set the addr_assign_type. Using NET_ADDR_STOLEN might be more appropriate in some of these cases. Please let me know, and I'll update the patch accordingly.

2013-09-03ftrace: Fix a slight race in modifying what function callback gets tracedSteven Rostedt (Red Hat)
There's a slight race when going from a list function to a non list function. That is, when only one callback is registered to the function tracer, it gets called directly by the mcount trampoline. But if this function has filters, it may be called by the wrong functions. As the list ops callback that handles multiple callbacks that are registered to ftrace, it also handles what functions they call. While the transaction is taking place, use the list function always, and after all the updates are finished (only the functions that should be traced are being traced), then we can update the trampoline to call the function directly.

2013-09-03NTB: Update Device IDsJon Mason
Add support for new Intel NTB devices on upcoming Xeon hardware. Since the Xeon hardware design is already in place in the driver, all that is needed are the new device ids. Remove the device IDs for NTB devs running in Transparent Bridge mode, as this driver is not being used for those devices. Rename the device IDs for NTB devs running in NTB-RP mode to better identify their usage model. "PS" to denote the Primary Side of NTB, and "SS" to denote the secondary side. The primary side is the interface exposed to the local system, and the secondary side is the interface exposed to the remote system. Signed-off-by: Jon Mason <jon.mason@intel.com>
2013-09-03NTB: BWD Link RecoveryJon Mason
The BWD NTB device will drop the link if an error is encountered on the point-to-point PCI bridge. The link will stay down until all errors are cleared and the link is re-established. On link down, check to see if the error is detected, if so do the necessary housekeeping to try and recover from the error and reestablish the link. There is a potential race between the 2 NTB devices recovering at the same time. If the times are synchronized, the link will not recover and the driver will be stuck in this loop forever. Add a random interval to the recovery time to prevent this race. Signed-off-by: Jon Mason <jon.mason@intel.com>

2013-09-03MIPS: ath79: Switch to the clkdev frameworkGabor Juhos
The ath79 code uses static clock devices and provides its own clk_{get,put} implementations. Change the code to use dynamically allocated clock devices and register the clocks within the clkdev framework. Additionally, remove the local clk_{get,put} implementation. The clkdev framework has a common implementation of those. Also move the call of ath79_clock_init() from plat_mem_init() to plat_time_init(). Otherwise it would not be possible to use memory allocation functions from ath79clock_init() becasuse the memory subsystem is not yet initialized when plat_mem_init() runs.

Instead of accessing the rate field of the static clock devices directly, use the recently introduced helper function to get the rate of the basic clocks. The static ath79_{ahb,cpu,ddr,ref}_clk variables will be removed by a subsequent patch. The actual change is in preparation of that. Also move the clock frequency printing code into the plat_time_init function. We are getting the cpu clock rate there already so we can save an extra call of the helper.

2013-09-03MIPS: ath79: Fix ar933x watchdog clockFelix Fietkau
The watchdog device on the AR933x is connected to the AHB clock, however the current code uses the reference clock. Due to the wrong rate, the watchdog driver can't calculate correct register values for a given timeout value and the watchdog unexpectedly restarts the system. The code uses the wrong value since the initial commit 04225e1d227c8e68d685936ecf42ac175fec0e54 (MIPS: ath79: add AR933X specific clock init) The patch fixes the code to use the correct clock rate to avoid the problem.
