      ksmbd: add mnt_want_write to ksmbd vfs functions · 40b268d3
      Namjae Jeon authored 
      ksmbd is doing write access using vfs helpers. There are the cases that
mnt_want_write() is not called in vfs helper. This patch add missing
mnt_want_write() to ksmbd vfs functions.

      ksmbd: validate command payload size · 2b9b8f3b
      Namjae Jeon authored 
      ->StructureSize2 indicates command payload size. ksmbd should validate
this size with rfc1002 length before accessing it.
This patch remove unneeded check and add the validation for this.

      vhost: Fix worker hangs due to missed wake up calls · 4b13cbef
      Mike Christie authored 
      We can race where we have added work to the work_list, but
vhost_task_fn has passed that check but not yet set us into
TASK_INTERRUPTIBLE. wake_up_process will see us in TASK_RUNNING and
just return.

This bug was intoduced in commit f9010dbd ("fork, vhost: Use
CLONE_THREAD to fix freezer/ps regression") when I moved the setting
of TASK_INTERRUPTIBLE to simplfy the code and avoid get_signal from
logging warnings about being in the wrong state. This moves the setting
of TASK_INTERRUPTIBLE back to before we test if we need to stop the
task to avoid a possible race there as well. We then have vhost_worker
set TASK_RUNNING if it finds work similar to before.

Fixes: f9010dbd ("fork, vhost: Use CLONE_THREAD to fix freezer/ps regression")

      vhost: Fix crash during early vhost_transport_send_pkt calls · a284f09e
      Mike Christie authored 
      If userspace does VHOST_VSOCK_SET_GUEST_CID before VHOST_SET_OWNER we
can race where:
1. thread0 calls vhost_transport_send_pkt -> vhost_work_queue
2. thread1 does VHOST_SET_OWNER which calls vhost_worker_create.
3. vhost_worker_create will set the dev->worker pointer before setting
the worker->vtsk pointer.
4. thread0's vhost_work_queue will see the dev->worker pointer is
set and try to call vhost_task_wake using not yet set worker->vtsk
pointer.
5. We then crash since vtsk is NULL.

Before commit 6e890c5d ("vhost: use vhost_tasks for worker
threads"), we only had the worker pointer so we could just check it to
see if VHOST_SET_OWNER has been done. After that commit we have the
vhost_worker and vhost_task pointer, so we can now hit the bug above.

This patch embeds the vhost_worker in the vhost_dev and moves the work
list initialization back to vhost_dev_init, so we can just check the
worker.vtsk pointer to check if VHOST_SET_OWNER has been done like
before.

Fixes: 6e890c5d ("vhost: use vhost_tasks for worker threads")

In case of no-retriable error and zcopy do not revert upend_idx
to pass packet data (that is update used_idx in corresponding
vhost_zerocopy_signal_used()) as if packet data has been
transferred successfully.

      vdpa/mlx5: Fix hang when cvq commands are triggered during device unregister · 73790bdf
      Dragos Tatulea authored 
      Currently the vdpa device is unregistered after the workqueue that
processes vq commands is disabled. However, the device unregister
process can still send commands to the cvq (a vlan delete for example)
which leads to a hang because the handing workqueue has been disabled
and the command never finishes:

The fix is to disable and destroy the workqueue after the device
unregister. It is expected that vhost will not trigger kicks after
the unregister. But even if it would, the wq is disabled already by
setting the pointer to NULL (done so in the referenced commit).

Fixes: ad6dc1da ("vdpa/mlx5: Avoid processing works if workqueue was destroyed")

      tools/virtio: Fix arm64 ringtest compilation error · 57380fd1
      Rong Tao authored 
      Add cpu_relax() for arm64 instead of directly assert(), and add assert.h
header file. Also, add smp_wmb and smp_mb for arm64.

Compilation error as follows, avoid __always_inline undefined.
