Linus Torvalds 2ac9b9735b SCSI fixes on 20160625
Two straightforward fixes.  One is a concurrency issue only affecting
 SAS connected SATA drives, but which could hang the storage subsystem
 if it triggers (because the outstanding command count on error never
 goes back to zero) and the other is a NO_TAG fallout from the switch
 to hostwide tags which causes the system to crash on module insertion
 (we've checked carefully and only the 53c700 family of drivers is
 vulnerable to this issue).

Wei Fang 72d8c36ec3 scsi: fix race between simultaneous decrements of ->host_failed
sas_ata_strategy_handler() adds the works of the ata error handler to
system_unbound_wq. This workqueue asynchronously runs work items, so the
ata error handler will be performed concurrently on different CPUs. In
this case, ->host_failed will be decreased simultaneously in
scsi_eh_finish_cmd() on different CPUs, and become abnormal.

It will lead to permanently inequality between ->host_failed and
->host_busy, and scsi error handler thread won't start running. IO
errors after that won't be handled.

Since all scmds must have been handled in the strategy handler, just
remove the decrement in scsi_eh_finish_cmd() and zero ->host_busy after
the strategy handler to fix this race.

Tony Makkiel 7cfe749fad leds: core: Fix brightness setting upon hardware blinking enabled
Commit 76931edd54 ("leds: fix brightness changing when software blinking
is active") changed the semantics of led_set_brightness() which according
to the documentation should disable blinking upon any brightness setting.
Moreover it made it different for soft blink case, where it was possible
to change blink brightness, and for hardware blink case, where setting
any brightness greater than 0 was ignored.

While the change itself is against the documentation claims, it was driven
also by the fact that timer trigger remained active after turning blinking
off. Fixing that would have required major refactoring in the led-core,
led-class, and led-triggers because of cyclic dependencies.

Finally, it has been decided that allowing for brightness change during
blinking is beneficial as it can be accomplished without disturbing
blink rhythm.

The change in brightness setting semantics will not affect existing
LED class drivers that implement blink_set op thanks to the LED_BLINK_SW
flag introduced by this patch. The flag state will be from now on checked
in led_set_brightness() which will allow to distinguish between software
and hardware blink mode. In the latter case the control will be passed
directly to the drivers which apply their semantics on brightness set,
which is disable the blinking in case of most such drivers. New drivers
will apply new semantics and just change the brightness while hardware
blinking is on, if possible.

The issue was smuggled by subsequent LED core improvements, which modified
the code that originally introduced the problem.

Greg Kroah-Hartman 03cce00b4b First round of iio fixes for the 4.7 cycle.
A slightly bumper set due to travel delaying the pull request and a fair few
 issues with the recent merge window patches.  Patches all over the place.
 The st-sensors one is probably the most involved, but definitly solves the
 issues seen.  Note there are some other issues around that handler
 (and the fact that a lot of boards tie a level interrupt chip to an
 edge interrupt only irq chip).  These are not regressions however, so
 will turn up the slow route.
 
 * core
   - iio_trigger_attach_pollfunc had some really badly wrong error handling.
   Another nasty triggered whilst chasing down issues with the st sensors
   rework below.
 * ad5592r
   - fix an off by one error when allocating channels.
 * am2315
   - a stray mutex unlock before we ever take the lock.
 * apds9960
   - missing a parent in the driver model (which should be the i2c device).
   Result is it doesn't turn up under /sys/bus/i2c/devices which some
   userspace code uses for repeatable device identification.
 * as3935
   - ABI usage bug which meant a processed value was reported as raw. Now
     reporting scale as well to ensure userspace has the info it needs.
   - Don't return processed value via the buffer - it doesn't conform to
     the ABI and will overflow in some cases.
   - Fix a wrongly sized buffer which would overflow trashing part of the
     stack.  Also move it onto the heap as part of the fix.
 * bh1780
   - a missing return after write in debugfs lead to an incorrect read and
     a null pointer dereference.
   - dereferencing the wrong pointer in suspend and resume leading to
     unpredictable results.
   - assign a static name to avoid accidentally ending up with no name if
     loaded via device tree.
 * bmi160
   - output data rate for the accelerometer was incorrectly reported. Fix it.
   - writing the output data rate was also wrong due to reverse parameters.
 * bmp280
   - error message for wrong chip ID gave the wrong expected value.
 * hdc100x
   - mask for writing the integration time was wrong allowin g us to get
   'stuck' in a particular value with no way back.
   - temperature reported in celsius rather than millicelsius as per the
   ABI.
   - Get rid of some incorrect data shifting which lead to readings being
   rather incorrect.
 * max44000
   - drop scale attribute for proximity as it is an unscaled value (depends
     on what is in range rather than anything knowable at the detector).
 * st-pressure
   - ABI compliance fixes - units were wrong.
 * st-sensors
   - We introduced some nasty issues with the recent switch over to a
   a somewhat threaded handler in that we broke using a software trigger
   with these devices.  Now do it properly.  It's a larger patch than ideal
   for a fix, but the logic is straight forward.
   - Make sure the trigger is initialized before requesting the interrupt.
   This matters now the interrupt can be shared. Before it was ugly and wrong
   but short of flakey hardware could not be triggered.
   - Hammer down the dataready pin at boot - otherwise with really
   unlucky timing things could get interestingly wedged requiring a hard power
   down of the chip.

  with these devices.  Now do it properly.  It's a larger patch than ideal
  for a fix, but the logic is straight forward.
  - Make sure the trigger is initialized before requesting the interrupt.
  This matters now the interrupt can be shared. Before it was ugly and wrong
  but short of flakey hardware could not be triggered.
  - Hammer down the dataready pin at boot - otherwise with really
  unlucky timing things could get interestingly wedged requiring a hard power
  down of the chip.

  KEYS: Add placeholder for KDF usage with DH
2016-06-05 11:02:00 -07:00
Eric W. Biederman eedf265aa0 devpts: Make each mount of devpts an independent filesystem.
The /dev/ptmx device node is changed to lookup the directory entry "pts"
in the same directory as the /dev/ptmx device node was opened in.  If
there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx
uses that filesystem.  Otherwise the open of /dev/ptmx fails.

The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that
userspace can now safely depend on each mount of devpts creating a new
instance of the filesystem.

Each mount of devpts is now a separate and equal filesystem.

Reserved ttys are now available to all instances of devpts where the
mounter is in the initial mount namespace.

A new vfs helper path_pts is introduced that finds a directory entry
named "pts" in the directory of the passed in path, and changes the
passed in path to point to it.  The helper path_pts uses a function
path_parent_directory that was factored out of follow_dotdot.

In the implementation of devpts:
 - devpts_mnt is killed as it is no longer meaningful if all mounts of
   devpts are equal.
 - pts_sb_from_inode is replaced by just inode->i_sb as all cached
   inodes in the tty layer are now from the devpts filesystem.
 - devpts_add_ref is rolled into the new function devpts_ptmx.  And the
   unnecessary inode hold is removed.
 - devpts_del_ref is renamed devpts_release and reduced to just a
   deacrivate_super.
 - The newinstance mount option continues to be accepted but is now
   ignored.

In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as
they are never used.

Documentation/filesystems/devices.txt is updated to describe the current
situation.

This has been verified to work properly on openwrt-15.05, centos5,
centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3,
ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1,
slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01.  With the
caveat that on centos6 and on slackware-14.1 that there wind up being
two instances of the devpts filesystem mounted on /dev/pts, the lower
copy does not end up getting used.

Stephan Mueller 4693fc734d KEYS: Add placeholder for KDF usage with DH
The values computed during Diffie-Hellman key exchange are often used
in combination with key derivation functions to create cryptographic
keys.  Add a placeholder for a later implementation to configure a
key derivation function that will transform the Diffie-Hellman
result returned by the KEYCTL_DH_COMPUTE command.

[This patch was stripped down from a patch produced by Mat Martineau that
 had a bug in the compat code - so for the moment Stephan's patch simply
 requires that the placeholder argument must be NULL]

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull more rdma updates from Doug Ledford:
 "This is the second group of code for the 4.7 merge window.  It looks
  large, but only in one sense.  I'll get to that in a minute.  The list
  of changes here breaks down as follows:

   - Dynamic counter infrastructure in the IB drivers

     This is a sysfs based code to allow free form access to the
     hardware counters RDMA devices might support so drivers don't need
     to code this up repeatedly themselves

   - SendOnlyFullMember multicast support

   - IB router support

   - A couple misc fixes

   - The big item on the list: hfi1 driver updates, plus moving the hfi1
     driver out of staging

  There was a group of 15 patches in the hfi1 list that I thought I had
  in the first pull request but they weren't.  So that added to the
  length of the hfi1 section here.

  As far as these go, everything but the hfi1 is pretty straight
  forward.

  The hfi1 is, if you recall, the driver that Al had complaints about
  how it used the write/writev interfaces in an overloaded fashion.  The
  write portion of their interface behaved like the write handler in the
  IB stack proper and did bi-directional communications.  The writev
  interface, on the other hand, only accepts SDMA request structures.
  The completions for those structures are sent back via an entirely
  different event mechanism.

  With the security patch, we put security checks on the write
  interface, however, we also knew they would be going away soon.  Now,
  we've converted the write handler in the hfi1 driver to use ioctls
  from the IB reserved magic area for its bidirectional communications.
  With that change, Intel has addressed all of the items originally on
  their TODO when they went into staging (as well as many items added to
  the list later).

  As such, I moved them out, and since they were the last item in the
  staging/rdma directory, and I don't have immediate plans to use the
  staging area again, I removed the staging/rdma area.

  Because of the move out of staging, as well as a series of 5 patches
  in the hfi1 driver that removed code people thought should be done in
  a different way and was optional to begin with (a snoop debug
  interface, an eeprom driver for an eeprom connected directory to their
  hfi1 chip and not via an i2c bus, and a few other things like that),
  the line count, especially the removal count, is high"

Antony Pavlov 5214cae77c MIPS: devicetree: fix cpu interrupt controller node-names
Here is the quote from [1]:

    The unit-address must match the first address specified
    in the reg property of the node. If the node has no reg property,
    the @ and unit-address must be omitted and the node-name alone
    differentiates the node from other nodes at the same level

This patch adjusts MIPS dts-files and devicetree binding
documentation in accordance with [1].

   - Additionally, it turns out that I missed a prerequisite for

Al Viro 3767e255b3 switch ->setxattr() to passing dentry and inode separately
smack ->d_instantiate() uses ->setxattr(), so to be able to call it before
we'd hashed the new dentry and attached it to inode, we need ->setxattr()
instances getting the inode as an explicit argument rather than obtaining
it from dentry.

Similar change for ->getxattr() had been done in commit ce23e64.  Unlike
->getxattr() (which is used by both selinux and smack instances of
->d_instantiate()) ->setxattr() is used only by smack one and unfortunately
it got missed back then.

Really sorry about this late pull request.  It looks like at the time I
 sent my pull request for v4.7 there was some conflict or other issue
 which caused my script to stop merging the ASoC branches at some point
 after the HDMI changes.
 
 It's all specific driver updates, including:
 
  - New drivers for MAX98371 and TAS5720.
  - SPI support for TLV320AIC32x4.
  - TDM support for STI Uniperf IPs.
 
 This code should all have been in -next prior to the merge window apart
 from some fixes, it dropped out on the 18th.

ASoC: Updates for v4.7 part 2

Really sorry about this late pull request.  It looks like at the time I
sent my pull request for v4.7 there was some conflict or other issue
which caused my script to stop merging the ASoC branches at some point
after the HDMI changes.

It's all specific driver updates, including:

 - New drivers for MAX98371 and TAS5720.
 - SPI support for TLV320AIC32x4.
 - TDM support for STI Uniperf IPs.

This code should all have been in -next prior to the merge window apart
from some fixes, it dropped out on the 18th.
