2013-06-19sparc32, leon: Enable interrupts before going idle to avoid getting stuckAndreas Larsson
This enables interrupts for Leon before having the CPU enter power-down mode. Commit 87fa05aeb3a5e8e21b1a5510eef6983650eff092, "sparc: Use generic idle loop", gets the CPU stuck on idle for Leon systems. On Leon, disabling interrupts and powering down the processor will get the processor stuck waiting for an interrupt that will never be reacted to.

2013-06-19sparc32, leon: Remove separate "ticker" timer for SMPAndreas Larsson
This reduces the need from two timers to one timer. Moreover, without this patch, when the "ticker" timer triggers timer_cs_read via tick_periodic it reads the value of the usual timer it can get an wrapped timer value without timer_cs_internal_counter having been updated leading to the clock going backwards. This effectively hangs one cpu that gets stuck in update_wall_time with an offset slightly smaller than 0xffffffffffffffff.

Joshua reported: Commit cd7b304dfaf1 (x86, range: fix missing merge during add range) broke mtrr cleanup on his setup in 3.9.5. corresponding commit in upstream is fbe06b7bae7c. The reason is add_range_with_merge could generate blank spot. We could avoid that by searching new expanded start/end, that new range should include all connected ranges in range array. At last add the new expanded start/end to the range array. Also move up left array so do not add new blank slot in the range array. -v2: move left array to avoid enhance add_range() -v3: include fix from Joshua about memmove declaring when DYN_DEBUG is used.

2013-06-17vlan: restore ethtool ABI to control VLAN hardware accelerationFernando Luis Vazquez Cao
As part of the push to add 802.1ad server provider tagging support to the kernel the VLAN features flags were renamed. Unfortunately the kernel name for the VLAN hardware acceleration features that the kernel shows user space was included in the rename, which broke ethtool (txvlan and rxvlan options do not work). This patch restores the original names, i.e. the original ABI. If we wanted to make clear to users that we are refering to CTAGs we can always change ethtool's short_name and long_name for these features (for example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload -> tx-vlan-ctag-offload).

2013-06-18fuse: hold i_mutex in fuse_file_fallocate()Maxim Patlasov
Changing size of a file on server and local update (fuse_write_update_size) should be always protected by inode->i_mutex. Otherwise a race like this is possible: 1. Process 'A' calls fallocate(2) to extend file (~FALLOC_FL_KEEP_SIZE). fuse_file_fallocate() sends FUSE_FALLOCATE request to the server. 2. Process 'B' calls ftruncate(2) shrinking the file. fuse_do_setattr() sends shrinking FUSE_SETATTR request to the server and updates local i_size by i_size_write(inode, outarg.attr.size). 3. Process 'A' resumes execution of fuse_file_fallocate() and calls fuse_write_update_size(inode, offset + length). But 'offset + length' was obsoleted by ftruncate from previous step. Changed in v2 (thanks Brian and Anand for suggestions): - made relation between mutex_lock() and fuse_set_nowrite(inode) more explicit and clear. - updated patch description to use ftruncate(2) in example Signed-off-by: Maxim V.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless John W. Linville says: ==================== This will probably be the last batch of wireless fixes intended for 3.10. Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot. Daniel Drake fixes a race condition in btmrvl that causes hangs on suspend for OLPC hardware. Johan Hedberg adds a check to avoid sending a HCI_Delete_Stored_Link_Key command to devices that don't support them, avoiding some scary looking log spam. Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates higher than 1Mb/s on older wireless networks.

2013-06-17alx: add a simple AR816x/AR817x device driverJohannes Berg
This is a very simple driver, based on the original vendor driver that Qualcomm/Atheros published/submitted previously, but reworked to make the code saner. However, it also lost a number of features (TSO/GSO, VLAN acceleration and multi- queue support) in the process, as well as debugging support features I didn't have any use for. The only thing I left is checksum offload. More features can obviously be added, but this seemed like a good start for having a driver in mainline at all. Johannes Stezenbach has verified that the driver works on AR8161, I have a AR8171 myself. The E2200 device ID I found on github in somebody's repository.

We should call __vlan_hwaccel_put_tag() only if the packet comes from vlan, otherwise VLAN_TAG_PRESENT will always be added.

2013-06-17vxlan: only migrate dynamic FDB entriesstephen hemminger
Only migrate dynamic forwarding table entries, don't modify static entries. If packet received from incorrect source IP address assume it is an imposter and drop it. This patch applies only to -net, a different patch would be needed for earlier kernels since the NTF_SELF flag was introduced with 3.10.

It is possible for a packet to arrive during vxlan_stop(), and have a dynamic entry created. Close this by checking if device is up.

2013-06-17ARM: 7759/1: decouple CPU offlining from reboot/shutdownStephen Warren
Add comments to machine_shutdown()/halt()/power_off()/restart() that describe their purpose and/or requirements re: CPUs being active/not. In machine_shutdown(), replace the call to smp_send_stop() with a call to disable_nonboot_cpus(). This completely disables all but one CPU, thus satisfying the requirement that only a single CPU be active for kexec. Adjust Kconfig dependencies for this change. In machine_halt()/power_off()/restart(), call smp_send_stop() directly, rather than via machine_shutdown(); these functions don't need to completely de-activate all CPUs using hotplug, but rather just quiesce them. Remove smp_kill_cpus(), and its call from smp_send_stop(). smp_kill_cpus() was indirectly calling smp_ops.cpu_kill() without calling smp_ops.cpu_die() on the target CPUs first. At least some implementations of smp_ops had issues with this; it caused cpu_kill() to hang on Tegra, for example. Since smp_send_stop() is only used for shutdown, halt, and power-off, there is no need to attempt any kind of CPU hotplug here. Adjust Kconfig to reflect that machine_shutdown() (and hence kexec) relies upon disable_nonboot_cpus(). However, this alone doesn't guarantee that hotplug will work, or even that hotplug is implemented for a particular piece of HW that a multi-platform zImage runs on. Hence, add error-checking to machine_kexec() to determine whether it did work.

Commit 699390354da6c258b65bf8fa79cfd5feaede50b6 ('pty: Ignore slave pty close() if never successfully opened') introduced a bug with ptys whereby a write() in parallel with an open() on an existing pty could mistakenly indicate an I/O error. Only indicate an I/O error if the condition on open() actually exists.

Commit 421b40a6286e ("tty/vt: Fix vc_deallocate() lock order") changed the behavior when deallocating VT 1. Previously if trying to deallocate VT1 and it is busy, we would return EBUSY. The commit changed this to return 0 (success). This commit restores the old behavior.
