2017-01-13KVM: arm/arm64: Fix occasional warning from the timer work functionChristoffer Dall
When a VCPU blocks (WFI) and has programmed the vtimer, we program a soft timer to expire in the future to wake up the vcpu thread when appropriate. Because such as wake up involves a vcpu kick, and the timer expire function can get called from interrupt context, and the kick may sleep, we have to schedule the kick in the work function. The work function currently has a warning that gets raised if it turns out that the timer shouldn't fire when it's run, which was added because the idea was that in that case the work should never have been cancelled. However, it turns out that this whole thing is racy and we can get spurious warnings. The problem is that we clear the armed flag in the work function, which may run in parallel with the kvm_timer_unschedule->timer_disarm() call. This results in a possible situation where the timer_disarm() call does not call cancel_work_sync(), which effectively synchronizes the completion of the work function with running the VCPU. As a result, the VCPU thread proceeds before the work function completees, causing changes to the timer state such that kvm_timer_should_fire(vcpu) returns false in the work function. All we do in the work function is to kick the VCPU, and an occasional rare extra kick never harmed anyone. Since the race above is extremely rare, we don't bother checking if the race happens but simply remove the check and the clearing of the armed flag from the work function.

2017-01-13fuse: clear FR_PENDING flag when moving requests out of pending queueTahsin Erdogan
fuse_abort_conn() moves requests from pending list to a temporary list before canceling them. This operation races with request_wait_answer() which also tries to remove the request after it gets a fatal signal. It checks FR_PENDING flag to determine whether the request is still in the pending list. Make fuse_abort_conn() clear FR_PENDING flag so that request_wait_answer() does not remove the request from temporary list. This bug causes an Oops when trying to delete an already deleted list entry in end_requests().

2017-01-13mac80211: initialize SMPS field in HT capabilitiesFelix Fietkau
ibss and mesh modes copy the ht capabilites from the band without overriding the SMPS state. Unfortunately the default value 0 for the SMPS field means static SMPS instead of disabled. This results in HT ibss and mesh setups using only single-stream rates, even though SMPS is not supposed to be active.

2017-01-12pmem: return EIO on read_pmem() failureStefan Hajnoczi
The read_pmem() function uses memcpy_mcsafe() on x86 where an EFAULT error code indicates a failed read. Block I/O should use EIO to indicate failure. Other pmem code paths (like bad blocks) already use EIO so let's be consistent.

2017-01-12nfs: Don't take a reference on fl->fl_file for LOCK operationBenjamin Coddington
I have reports of a crash that look like __fput() was called twice for a NFSv4.0 file. It seems possible that the state manager could try to reclaim a lock and take a reference on the fl->fl_file at the same time the file is being released if, during the close(), a signal interrupts the wait for outstanding IO while removing locks which then skips the removal of that lock. Since 83bfff23e9ed ("nfs4: have do_vfs_lock take an inode pointer") has removed the need to traverse fl->fl_file->f_inode in nfs4_lock_done(), taking that reference is no longer necessary.

git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-linus Johan writes: USB-serial fixes for v4.10-rc4 These fixes address a number of issues in the ch341 driver and includes a partial revert of a change in how we set the line settings that went into 4.10-rc1 but which turned out to have undesired side effects. This included deasserting the modem-control lines when configuring the device, but also prevented a certain class of CH340 devices from working with the driver. Included are also two fixes for two minor information leaks in kl5kusb105 and ch341 due to failures to detect short control transfers. Signed-off-by: Johan Hovold <johan@kernel.org>

2017-01-12block: Rename blk_queue_zone_size and bdev_zone_sizeDamien Le Moal
All block device data fields and functions returning a number of 512B sectors are by convention named xxx_sectors while names in the form xxx_size are generally used for a number of bytes. The blk_queue_zone_size and bdev_zone_size functions were not following this convention so rename them. No functional change is introduced by this patch. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Collapsed the two patches, they were nonsensically split and broke bisection. Signed-off-by: Jens Axboe <axboe@fb.com>
