The relevant code from iothread_run() is:

  while (!atomic_read(&iothread->stopping)) {
      aio_poll(iothread->ctx, true);

and iothread_stop():

  iothread->stopping = true;
  aio_notify(iothread->ctx);
  ...
  qemu_thread_join(&iothread->thread);

The following scenario can occur:

1. IOThread:
  while (!atomic_read(&iothread->stopping)) -> stopping=false

2. Main loop:
  iothread->stopping = true;
  aio_notify(iothread->ctx);

3. IOThread:
  aio_poll(iothread->ctx, true); -> hang

The bug is explained by the AioContext->notify_me doc comments:

  "If this field is 0, everything (file descriptors, bottom halves,
  timers) will be re-evaluated before the next blocking poll(), thus the
  event_notifier_set call can be skipped."

The problem is that "everything" does not include checking
iothread->stopping.  This means iothread_run() will block in aio_poll()
if aio_notify() was called just before aio_poll().

This patch fixes the hang by replacing aio_notify() with
aio_bh_schedule_oneshot().  This makes aio_poll() or g_main_loop_run()
to return.

Implementing this properly required a new bool running flag.  The new
flag prevents races that are tricky if we try to use iothread->stopping.
Now iothread->stopping is purely for iothread_stop() and
iothread->running is purely for the iothread_run() thread.

Stefan Hajnoczi 882e9b89af blockdev: add x-blockdev-set-iothread force boolean
When a node is already associated with a BlockBackend the
x-blockdev-set-iothread command refuses to set the IOThread.  This is to
prevent accidentally changing the IOThread when the nodes are in use.

When the nodes are created with -drive they automatically get a
BlockBackend.  In that case we know nothing is using them yet and it's
safe to set the IOThread.  Add a force boolean to override the check.

Paolo Bonzini bd6458e410 block: avoid recursive AioContext acquire in bdrv_inactivate_all()
BDRV_POLL_WHILE() does not support recursive AioContext locking.  It
only releases the AioContext lock once regardless of how many times the
caller has acquired it.  This results in a hang since the IOThread does
not make progress while the AioContext is still locked.

The following steps trigger the hang:

  $ qemu-system-x86_64 -M accel=kvm -m 1G -cpu host \
                       -object iothread,id=iothread0 \

Mark Kanda 0a75b60cdb virtio-blk: reject configs with logical block size > physical block size
virtio-blk logical block size should never be larger than physical block
size because it doesn't make sense to have such configurations. QEMU doesn't
have a way to effectively express this condition; the best it can do is
report the physical block exponent as 0 - indicating the logical block size
equals the physical block size.

This is identical to commit 3da023b582
but applied to virtio-blk (instead of virtio-scsi).

Stefan Hajnoczi ca00bbb153 blockdev: add x-blockdev-set-iothread testing command
Currently there is no easy way for iotests to ensure that a BDS is bound
to a particular IOThread.  Normally the virtio-blk device calls
blk_set_aio_context() when dataplane is enabled during guest driver
initialization.  This never happens in iotests since -machine
accel=qtest means there is no guest activity (including device driver
initialization).

This patch adds a QMP command to explicitly assign IOThreads in test
cases.  See qapi/block-core.json for a description of the command.

Stefan Hajnoczi 2d24b60b77 block: don't keep AioContext acquired after external_snapshot_prepare()
It is not necessary to hold AioContext across transactions anymore since
bdrv_drained_begin/end() is used to keep the nodes quiesced.  In fact,
using the AioContext lock for this purpose was always buggy.

This patch reduces the scope of AioContext locked regions.  This is not
just a cleanup but also fixes hangs that occur in BDRV_POLL_WHILE()
because it is unware of recursive locking and does not release the
AioContext the necessary number of times to allow progress to be made.

Stefan Hajnoczi b9464ba19f blockdev: hold AioContext for bdrv_unref() in external_snapshot_clean()
bdrv_unref() requires the AioContext lock because bdrv_flush() uses
BDRV_POLL_WHILE(), which assumes the AioContext is currently held.  If
BDRV_POLL_WHILE() runs without AioContext held the
pthread_mutex_unlock() call in aio_context_release() fails.

This patch moves bdrv_unref() into the AioContext locked region to solve
the following pthread_mutex_unlock() failure:

Stefan Hajnoczi 78f1d3d6a6 coroutine: simplify co_aio_sleep_ns() prototype
The AioContext pointer argument to co_aio_sleep_ns() is only used for
the sleep timer.  It does not affect where the caller coroutine is
resumed.

Due to changes to coroutine and AIO APIs it is now possible to drop the
AioContext pointer argument.  This is safe to do since no caller has
specific requirements for which AioContext the timer must run in.

This patch drops the AioContext pointer argument and renames the
function to simplify the API.
