syzbot reports a use-after-free in io_ring_file_ref_switch() when it
tries to switch back to percpu mode. When we put the final reference to
the table by calling percpu_ref_kill_and_confirm(), we don't want the
zero reference to queue async work for flushing the potentially queued
up items. We currently do a few flush_work(), but they merely paper
around the issue, since the work item may not have been queued yet
depending on the when the percpu-ref callback gets run.
Coming into the file unregister, we know we have the ring quiesced.
io_ring_file_ref_switch() can check for whether or not the ref is dying
or not, and not queue anything async at that point. Once the ref has
been confirmed killed, flush any potential items manually.

If we're using SQPOLL for kernel side submission and we shutdown the

doing the submission. This means we may miss cancelling some work, which
results in the io_uring shutdown hanging forever.

Currently, each time nfs4_do_fsinfo() is called it will do an implicit
NFS4 lease renewal, which is not compliant with the NFS4 specification.
This can result in a lease being expired by an NFS server.
Commit 83ca7f5ab3 ("NFS: Avoid PUTROOTFH when managing leases")
introduced implicit client lease renewal in nfs4_do_fsinfo(),
which can result in the NFSv4.0 lease to expire on a server side,
and servers returning NFS4ERR_EXPIRED or NFS4ERR_STALE_CLIENTID.
This can easily be reproduced by frequently unmounting a sub-mount,
then stat'ing it to get it mounted again, which will delay or even
completely prevent client from sending RENEW operations if no other
NFS operations are issued. Eventually nfs server will expire client's
lease and return an error on file access or next RENEW.
This can also happen when a sub-mount is automatically unmounted
due to inactivity (after nfs_mountpoint_expiry_timeout), then it is
mounted again via stat(). This can result in a short window during
which client's lease will expire on a server but not on a client.
This specific case was observed on production systems.
This patch removes the implicit lease renewal from nfs4_do_fsinfo().

All async events are enqueued via nvmet_add_async_event() which
updates the ctrl->async_event_cmds[] array and additionally an struct
nvmet_async_event is added to the ctrl->async_events list.
Under normal operations the nvmet_async_event_work() updates again
the ctrl->async_event_cmds and removes the corresponding struct
nvmet_async_event from the list again. Though nvmet_sq_destroy() could
be called which calls nvmet_async_events_free() which only updates the
ctrl->async_event_cmds[] array.
Add new functions nvmet_async_events_process() and
nvmet_async_events_free() to process async events, update an array and

When we destroy submission queue after clearing the aen present on

After nvmet_install_queue() sets sq->ctrl calling to nvmet_sq_destroy()
reduces the controller refcount. In case nvmet_install_queue() fails,
calling to nvmet_ctrl_put() is done twice (at nvmet_sq_destroy and
nvmet_execute_io_connect/nvmet_execute_admin_connect) instead of once for
the queue which leads to use after free of the controller. Fix this by set
NULL at sq->ctrl in case of a failure at nvmet_install_queue().

When the directory is large and it's being modified by one client
while another client is doing the 'ls -l' on the same directory then
the cache page invalidation from nfs_force_use_readdirplus causes
the reading client to keep restarting READDIRPLUS from cookie 0
which causes the 'ls -l' to take a very long time to complete,
possibly never completing.
Currently when nfs_force_use_readdirplus is called to switch from
READDIR to READDIRPLUS, it invalidates all the cached pages of the
directory. This cache page invalidation causes the next nfs_readdir
to re-read the directory content from cookie 0.
This patch is to optimise the cache invalidation in
nfs_force_use_readdirplus by only truncating the cached pages from
last page index accessed to the end the file. It also marks the
inode to delay invalidating all the cached page of the directory
until the next initial nfs_readdir of the next 'ls' instance.

[Why]
In current code we're essentially drawing the cursor on every pipe
that contains it. This only works when the planes have the same
scaling for src to dest rect, otherwise we'll get "double cursor" where
one cursor is incorrectly filtered and offset from the real position.
[How]
Without dedicated cursor planes on DCN we require at least one pipe
that matches the scaling of the current timing.
This is an optimization and workaround for the most common case where
the top-most plane is not scaled but the bottom-most plane is scaled.
Whenever a pipe has a parent pipe in the blending tree whose recout
fully contains the current pipe we can disable the pipe.
This only applies when the pipe is actually visible of course.

Merge tag 'powerpc-5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"A pretty small batch for us, and apologies for it being a bit late, I
wanted to sneak Christophe's user_access_begin() series in.
Summary:
- Implement user_access_begin() and friends for our platforms that
support controlling kernel access to userspace.
- Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx.
- Some tweaks to our pseries IOMMU code to allow SVMs ("secure"
virtual machines) to use the IOMMU.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit
VDSO, and some other improvements.
- A series to use the PCI hotplug framework to control opencapi
card's so that they can be reset and re-read after flashing a new
FPGA image.
As well as other minor fixes and improvements as usual.

Pull overlayfs update from Miklos Szeredi:
- Try to preserve holes in sparse files when copying up, thus saving
disk space and improving performance.
- Fix a performance regression introduced in v4.19 by preserving
asynchronicity of IO when fowarding to underlying layers. Add VFS
helpers to submit async iocbs.
- Fix a regression in lseek(2) introduced in v4.19 that breaks >2G
seeks on 32bit kernels.
- Fix a corner case where st_ino/st_dev was not preserved across copy
up.
- Miscellaneous fixes and cleanups.

In the past it was possible to create multiple L2TPv3 sessions with the
same session id as long as the sessions belonged to different tunnels.
The resulting sessions had issues when used with IP encapsulated tunnels,
but worked fine with UDP encapsulated ones. Some applications began to
rely on this behaviour to avoid having to negotiate unique session ids.
Some time ago a change was made to require session ids to be unique across
all tunnels, breaking the applications making use of this "feature".
This change relaxes the duplicate session id check to allow duplicates
if both of the colliding sessions belong to UDP encapsulated tunnels.

As Eric noticed, tcindex_alloc_perfect_hash() uses cp->hash
to compute the size of memory allocation, but cp->hash is
set again after the allocation, this caused an out-of-bound
access.
So we have to move all cp->hash initialization and computation
before the memory allocation. Move cp->mask and cp->shift together
as cp->hash may need them for computation too.
