Linus Torvalds 155134fef2 Revert "proc: Point /proc/{mounts,net} at /proc/thread-self/{mounts,net} instead of /proc/self/{mounts,net}"
This reverts commits 344470cac4 and e813244072.

It turns out that the exact path in the symlink matters, if for somewhat
unfortunate reasons: some apparmor configurations don't allow dhclient
access to the per-thread /proc files.  As reported by Jörg Otte:

  audit: type=1400 audit(1407684227.003:28): apparmor="DENIED"
    operation="open" profile="/sbin/dhclient"
    name="/proc/1540/task/1540/net/dev" pid=1540 comm="dhclient"
    requested_mask="r" denied_mask="r" fsuid=0 ouid=0

so we had better revert this for now.  We might be able to work around
this in practice by only using the per-thread symlinks if the thread
isn't the thread group leader, and if the namespaces differ between
threads (which basically never happens).

We'll see. In the meantime, the revert was made to be intentionally easy.

Alex Estrin dd57c9308a IB/ipoib: Avoid multicast join attempts with invalid P_key
Currently, the parent interface keeps sending broadcast group join
requests even if p_key index 0 is invalid, which is possible/common in
virtualized environments where a VF has been probed to VM but the
actual P_key configuration has not yet been assigned by the management
software. This creates unnecessary noise on the fabric and in the
kernel logs:

    ib0: multicast join failed for ff12:401b:8000:0000:0000:0000:ffff:ffff, status -22

The original code run the multicast task regardless of the actual
P_key value, which can be avoided. The fix is to re-init resources and
bring interface up only if P_key index 0 is valid either when starting
up or on PKEY_CHANGE event.

Jeff Moyer 200612ec33 dm table: propagate QUEUE_FLAG_NO_SG_MERGE
Commit 05f1dd5 ("block: add queue flag for disabling SG merging")
introduced a new queue flag: QUEUE_FLAG_NO_SG_MERGE.  This gets set by
default in blk_mq_init_queue for mq-enabled devices.  The effect of
the flag is to bypass the SG segment merging.  Instead, the
bio->bi_vcnt is used as the number of hardware segments.

With a device mapper target on top of a device with
QUEUE_FLAG_NO_SG_MERGE set, we can end up sending down more segments
than a driver is prepared to handle.  I ran into this when backporting
the virtio_blk mq support.  It triggerred this BUG_ON, in
virtio_queue_rq:

        BUG_ON(req->nr_phys_segments + 2 > vblk->sg_elems);

The queue's max is set here:
        blk_queue_max_segments(q, vblk->sg_elems-2);

Basically, what happens is that a bio is built up for the dm device
(which does not have the QUEUE_FLAG_NO_SG_MERGE flag set) using
bio_add_page.  That path will call into __blk_recalc_rq_segments, so
what you end up with is bi_phys_segments being much smaller than bi_vcnt
(and bi_vcnt grows beyond the maximum sg elements).  Then, when the bio
is submitted, it gets cloned.  When the cloned bio is submitted, it will
end up in blk_recount_segments, here:

        if (test_bit(QUEUE_FLAG_NO_SG_MERGE, &q->queue_flags))
                bio->bi_phys_segments = bio->bi_vcnt;

and now we've set bio->bi_phys_segments to a number that is beyond what
was registered as queue_max_segments by the driver.

The right way to fix this is to propagate the queue flag up the stack.

The rules for propagating the flag are simple:
- if the flag is set for any underlying device, it must be set for the
  upper device
- consequently, if the flag is not set for any underlying device, it
  should not be set for the upper device.

Takashi Iwai e24aa0a4c5 ALSA: hda/ca0132 - Don't try loading firmware at resume when already failed
CA0132 driver tries to reload the firmware at resume.  Usually this
works since the firmware loader core caches the firmware contents by
itself.  However, if the driver failed to load the firmwares
(e.g. missing files), reloading the firmware at resume goes through
the actual file loading code path, and triggers a kernel WARNING like:

 WARNING: CPU: 10 PID:11371 at drivers/base/firmware_class.c:1105 _request_firmware+0x9ab/0x9d0()

For avoiding this situation, this patch makes CA0132 skipping the f/w
loading at resume when it failed at probe time.

Linus Torvalds fc335c1b68 This contains a fix for two long standing bugs. Both of which are
rarely ever hit, and requires the user to do something that users rarely
 do. It took a few special test cases to even trigger this bug,
 and one of them was just one test in the process of finishing up as another
 one started.
 
 Both bugs have to do with the ring buffer iterator rb_iter_peek(), but one
 is more indirect than the other.
 
 The fist bug fix is simply an increase in the safety net loop counter.
 The counter makes sure that the rb_iter_peek() only iterates the number
 of times we expect it can, and no more. Well, there was one way it could
 iterate one more than we expected, and that caused the ring buffer
 to shutdown with a nasty warning. The fix was simply to up that counter by
 one.
 
 The other bug has to be with rb_iter_reset() (called by rb_iter_peek()).
 This happens when a user reads both the trace_pipe and trace files.
 The trace_pipe is a consuming read and does not use the ring buffer
 iterator, but the trace file is not a consuming read and does use the
 ring buffer iterator. When the trace file is being read, if it detects
 that a consuming read occurred, it resets the iterator and starts over.
 But the reset code that does this (rb_iter_reset()), checks if the
 reader_page is linked to the ring buffer or not, and will look into
 the ring buffer itself if it is not. This is wrong, as it should always
 try to read the reader page first. Not to mention, the code that looked
 into the ring buffer did it wrong, and used the header_page "read" offset
 to start reading on that page. That offset is bogus for pages in the
 writable ring buffer, and was corrupting the iterator, and it would start
 returning bogus events.

  and trace files.  The trace_pipe is a consuming read and does not use
  the ring buffer iterator, but the trace file is not a consuming read
  and does use the ring buffer iterator.  When the trace file is being
  read, if it detects that a consuming read occurred, it resets the
  iterator and starts over.  But the reset code that does this
  (rb_iter_reset()), checks if the reader_page is linked to the ring
  buffer or not, and will look into the ring buffer itself if it is not.
  This is wrong, as it should always try to read the reader page first.
  Not to mention, the code that looked into the ring buffer did it
  wrong, and used the header_page "read" offset to start reading on that
  page.  That offset is bogus for pages in the writable ring buffer, and
  was corrupting the iterator, and it would start returning bogus
  events"

Linus Torvalds 77e40aae76 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
 "This is a bunch of small changes built against 3.16-rc6.  The most
  significant change for users is the first patch which makes setns
  drmatically faster by removing unneded rcu handling.

  The next chunk of changes are so that "mount -o remount,.." will not
  allow the user namespace root to drop flags on a mount set by the
  system wide root.  Aks this forces read-only mounts to stay read-only,
  no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec
  mounts to stay no exec and it prevents unprivileged users from messing
  with a mounts atime settings.  I have included my test case as the
  last patch in this series so people performing backports can verify
  this change works correctly.

  The next change fixes a bug in NFS that was discovered while auditing
  nsproxy users for the first optimization.  Today you can oops the
  kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever
  with pid namespaces.  I rebased and fixed the build of the
  !CONFIG_NFS_FS case yesterday when a build bot caught my typo.  Given
  that no one to my knowledge bases anything on my tree fixing the typo
  in place seems more responsible that requiring a typo-fix to be
  backported as well.

  The last change is a small semantic cleanup introducing
  /proc/thread-self and pointing /proc/mounts and /proc/net at it.  This
  prevents several kinds of problemantic corner cases.  It is a
  user-visible change so it has a minute chance of causing regressions
  so the change to /proc/mounts and /proc/net are individual one line
  commits that can be trivially reverted.  Unfortunately I lost and
  could not find the email of the original reporter so he is not
  credited.  From at least one perspective this change to /proc/net is a
  refgression fix to allow pthread /proc/net uses that were broken by
  the introduction of the network namespace"

Pull SElinux fixes from Paul Moore:
 "Two small patches to fix a couple of build warnings in SELinux and

  Both patches were posted earlier this week to the SELinux list, and
  that is where they sat as I didn't think there were noteworthy enough
  to go upstream at this point in time, but DaveM would rather see them
  upstream now so who am I to argue.  As the patches are both very
