b61c56227b sound fixes for 5.5-rc2
A small collection of fixes.  The main changes are fixes for a couple
 of regressions in AMD HD-audio and FireWire that were introduced in
 5.5-rc1.  The rest are small fixes for echoaudio and FireWire, as well
 as a usual Dell HD-audio fixup.

Merge tag 'io_uring-5.5-20191212' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:

 - A tweak to IOSQE_IO_LINK (also marked for stable) to allow links that
   don't sever if the result is < 0.

   This is mostly for linked timeouts, where if we ask for a pure
   timeout we always get -ETIME. This makes links useless for that case,
   hence allow a case where it works.

 - Five minor optimizations to fix and improve cases that regressed
   since v5.4.

 - An SQTHREAD locking fix.

 - A sendmsg/recvmsg iov assignment fix.

 - Net fix where read_iter/write_iter don't honor IOCB_NOWAIT, and
   subsequently ensuring that works for io_uring.

 - Fix a case where for an invalid opcode we might return -EBADF instead
   of -EINVAL, if the ->fd of that sqe was set to an invalid fd value.

* tag 'io_uring-5.5-20191212' of git://git.kernel.dk/linux-block:
  io_uring: ensure we return -EINVAL on unknown opcode
  io_uring: add sockets to list of files that support non-blocking issue
  net: make socket read/write_iter() honor IOCB_NOWAIT
  io_uring: only hash regular files for async work execution
  io_uring: run next sqe inline if possible
  io_uring: don't dynamically allocate poll data
  io_uring: deferred send/recvmsg should assign iov
  io_uring: sqthread should grab ctx->uring_lock for submissions

Pull FIELD_SIZEOF conversion from Kees Cook:
 "A mostly mechanical treewide conversion from FIELD_SIZEOF() to
  sizeof_field(). This avoids the redundancy of having 2 macros
  (actually 3) doing the same thing, and consolidates on sizeof_field().
  While "field" is not an accurate name, it is the common name used in
  the kernel, and doesn't result in any unintended innuendo.

  As there are still users of FIELD_SIZEOF() in -next, I will clean up
  those during this coming development cycle and send the final old
  macro removal patch at that time"

ecb6186cf7 block: fix NULL pointer dereference in account statistics with IDE
The IDE driver creates some passthru requests which never get
submitted to the block layer in such a way that blk_account_io_start()
gets called. However, the driver still calls __blk_mq_end_request() in
ide_end_rq() which will call blk_account_io_completion() which tries
to dereferences req->part which is never set. See ide_prep_sense() for
an example of where these requests come from.

To fix this, blk_account_io_completion() and blk_account_io_done()
should do nothing if req->part is not set.

The back trace of this bug is:

Pull AFS fixes from David Howells:
 "Fixes for AFS plus one patch to make debugging easier:

   - Fix how addresses are matched to server records. This is currently
     incorrect which means cache invalidation callbacks from the server
     don't necessarily get delivered correctly. This causes stale data
     and metadata to be seen under some circumstances.

   - Make the dynamic root superblock R/W so that rpm/dnf can reapply
     the SELinux label to it when upgrading the Fedora filesystem-afs
     package. If the filesystem is R/O, this fails and the upgrade
     fails.

     It might be better in future to allow setxattr from an LSM to
     bypass the R/O protections, if only for pseudo-filesystems.

   - Fix the parsing of mountpoint strings. The mountpoint object has to
     have a terminal dot, whereas the source/device string passed to
     mount should not. This confuses type-forcing suffix detection
     leading to the wrong volume variant being mounted.

   - Make lookups in the dynamic root superblock for creation events
     (such as mkdir) fail with EOPNOTSUPP rather than something like
     EEXIST. The dynamic root only allows implicit creation by the
     ->lookup() method - and only if the target cell exists.

   - Fix the looking up of an AFS superblock to include the cell in the
     matching key - otherwise all volumes with the same ID number are
     treated as the same thing, irrespective of which cell they're in.

   - Show the volume name of each volume in the volume records displayed
     in /proc/net/afs/<cell>/volumes. This proved useful in debugging as
     it provides a way to map the volume IDs to names, where the names
     are what appear in /proc/mounts"

9e3aa61ae3 io_uring: ensure we return -EINVAL on unknown opcode
If we submit an unknown opcode and have fd == -1, io_op_needs_file()
will return true as we default to needing a file. Then when we go and
assign the file, we find the 'fd' invalid and return -EBADF. We really
should be returning -EINVAL for that case, as we normally do for
unsupported opcodes.

Change io_op_needs_file() to have the following return values:

0   - does not need a file
1   - does need a file
< 0 - error value

and use this to pass back the right value for this invalid case.

d1c6a2aa02 pipe: simplify signal handling in pipe_read() and add comments
There's no need to separately check for signals while inside the locked
region, since we're going to do "wait_event_interruptible()" right
afterwards anyway, and the error handling is much simpler there.

The check for whether we had already read anything was also redundant,
since we no longer do the odd merging of reads when there are pending
writers.

But perhaps more importantly, this adds commentary about why we still
need to wake up possible writers even though we didn't read any data,
and why we can skip all the finishing touches now if we get a signal (or
had a signal pending) while waiting for more data.

[ This is a split-out cleanup from my "make pipe IO use exclusive wait
  queues" thing, which I can't apply because it triggers a nasty bug in
  the GNU make jobserver   - Linus ]

Fix missing cell comparison in afs_test_super().  Without this, any pair
volumes that have the same volume ID will share a superblock, no matter the
cell, unless they're in different network namespaces.

Normally, most users will only deal with a single cell and so they won't
see this.  Even if they do look into a second cell, they won't see a
problem unless they happen to hit a volume with the same ID as one they've
already got mounted.

1da4bd9f9d afs: Fix creation calls in the dynamic root to fail with EOPNOTSUPP
Fix the lookup method on the dynamic root directory such that creation
calls, such as mkdir, open(O_CREAT), symlink, etc. fail with EOPNOTSUPP
rather than failing with some odd error (such as EEXIST).

lookup() itself tries to create automount directories when it is invoked.
These are cached locally in RAM and not committed to storage.

158d583353 afs: Fix mountpoint parsing
Each AFS mountpoint has strings that define the target to be mounted.  This
is required to end in a dot that is supposed to be stripped off.  The
string can include suffixes of ".readonly" or ".backup" - which are
supposed to come before the terminal dot.  To add to the confusion, the "fs
lsmount" afs utility does not show the terminal dot when displaying the
string.

The kernel mount source string parser, however, assumes that the terminal
dot marks the suffix and that the suffix is always "" and is thus ignored.
In most cases, there is no suffix and this is not a problem - but if there
is a suffix, it is lost and this affects the ability to mount the correct
volume.

The command line mount command, on the other hand, is expected not to
include a terminal dot - so the problem doesn't arise there.

Fix this by making sure that the dot exists and then stripping it when
passing the string to the mount configuration.

750bde2fd4 drm/i915: Serialise with remote retirement
Since retirement may be running in a worker on another CPU, it may be
skipped in the local intel_gt_wait_for_idle(). To ensure the state is
consistent for our sanity checks upon load, serialise with the remote
retirer by waiting on the timeline->mutex.

Outside of this use case, e.g. on suspend or module unload, we expect the
slack to be picked up by intel_gt_pm_wait_for_idle() and so prefer to
put the special case serialisation with retirement in its single user,
for now at least.

10d5934557 io_uring: add sockets to list of files that support non-blocking issue
In chasing a performance issue between using IORING_OP_RECVMSG and
IORING_OP_READV on sockets, tracing showed that we always punt the
socket reads to async offload. This is due to io_file_supports_async()
not checking for S_ISSOCK on the inode. Since sockets supports the
O_NONBLOCK (or MSG_DONTWAIT) flag just fine, add sockets to the list
of file types that we can do a non-blocking issue to.

the iocb IOCB_NOWAIT flag. This breaks users like preadv2/pwritev2
and io_uring that rely on not having the file itself marked nonblocking,

This essentially reverts commit e944475e69. For high poll ops
workloads, like TAO, the dynamic allocation of the wait_queue
entry for IORING_OP_POLL_ADD adds considerable extra overhead.
Go back to embedding the wait_queue_entry, but keep the usage of
wait->private for the pointer stashing.

4e88d6e779 io_uring: allow unbreakable links
Some commands will invariably end in a failure in the sense that the
completion result will be less than zero. One such example is timeouts
that don't have a completion count set, they will always complete with
-ETIME unless cancelled.

For linked commands, we sever links and fail the rest of the chain if
the result is less than zero. Since we have commands where we know that
will happen, add IOSQE_IO_HARDLINK as a stronger link that doesn't sever
regardless of the completion result. Note that the link will still sever
if we fail submitting the parent request, hard links are only resilient
in the presence of completion results for requests that did submit
correctly.
