This regression can be reproduced with ntfs-3g and overlayfs:
mkdir lower upper work overlay
dd if=/dev/zero of=ntfs.raw bs=1M count=2
mkntfs -F ntfs.raw
mount ntfs.raw lower
touch lower/file.txt
mount -t overlay -o lowerdir=lower,upperdir=upper,workdir=work - overlay
mv overlay/file.txt overlay/file2.txt
mv fails and (misleadingly) prints
mv: cannot move 'overlay/file.txt' to a subdirectory of itself, 'overlay/file2.txt'
The reason is that ovl_copy_fileattr() is triggered due to S_NOATIME being
set on all inodes (by fuse) regardless of fileattr.
ovl_copy_fileattr() tries to retrieve file attributes from lower file, but
that fails because filesystem does not support this ioctl (this should fail
with ENOTTY, but ntfs-3g return EINVAL instead). This failure is
propagated to origial operation (in this case rename) that triggered the
copy-up.
The fix is to ignore ENOTTY and EINVAL errors from fileattr_get() in copy
up. This also requires turning the internal ENOIOCTLCMD into ENOTTY.
As a further measure to prevent unnecessary failures, only try the
fileattr_get/set on upper if there are any flags to copy up.
Side note: a number of filesystems set S_NOATIME (and sometimes other inode
flags) irrespective of fileattr flags. This causes unnecessary calls
during copy up, which might lead to a performance issue, especially if
latency is high. To fix this, the kernel would need to differentiate
between the two cases. E.g. introduce SB_NOATIME_UPDATE, a per-sb variant
of S_NOATIME. SB_NOATIME doesn't work, because that's interpreted as
"filesystem doesn't store an atime attribute"

The postclose handler can run after the device has been removed (or the
driver has been unbound) since userspace clients are free to hold the
file open as long as they want. Because the device removal callback
frees the entire nouveau_drm structure, any reference to it in the
postclose handler will result in a use-after-free.
To reproduce this, one must simply open the device file, unbind the
driver (or physically remove the device), and then close the device
file. This was found and can be reproduced easily with the IGT
core_hotunplug tests.
To avoid this, all clients are cleaned up in the device finalization
rather than deferring it to the postclose handler, and the postclose
handler is protected by a critical section which ensures the
drm_dev_unplug() and the postclose handler won't race.
This is not an ideal fix, since as I understand the proposed plan for
the kernel<->userspace interface for hotplug support, destroying the
client before the file is closed will cause problems. However, I believe
to properly fix this issue, the lifetime of the nouveau_drm structure
needs to be extended to match the drm_device, and this proved to be a
rather invasive change. Thus, I've broken this out so the fix can be
easily backported.
This fixes with the two previous commits CVE-2020-27820 (Karol).

__register_blkdev() is used to register a probe callback, and
that callback is typically used to call add_disk(). Now that
we are able to capture errors for add_disk(), we need to fix
those probe calls where add_disk() fails and clean up resources.
We don't extend the probe call to return the error given:
1) we'd have to always special-case the case where the disk
was already present, as otherwise concurrent requests to
open an existing block device would fail, and this would be
a userspace visible change
2) the error from ilookup() on blkdev_get_no_open() is sufficient
3) The only thing the probe call is used for is to support
pre-devtmpfs, pre-udev semantics that want to create disks when
their pre-created device node is accessed, and so we don't care
for failures on probe there.
Expand documentation for the probe callback to ensure users cleanup
resources if add_disk() is used and to clarify this interface may be
removed in the future.

Commit bf9c0538e4 ("ataflop: use a separate gendisk for each media
format") introduced ataflop_probe_lock mutex, but forgot to unlock the
mutex when atari_floppy_init() (i.e. module loading) succeeded. This will
result in double lock deadlock if ataflop_probe() is called. Also,
unregister_blkdev() must not be called from atari_floppy_init() with
ataflop_probe_lock held when atari_floppy_init() failed, for
ataflop_probe() waits for ataflop_probe_lock with major_names_lock held
(i.e. AB-BA deadlock).
__register_blkdev() needs to be called last in order to avoid calling
ataflop_probe() when atari_floppy_init() is about to fail, for memory for
completing already-started ataflop_probe() safely will be released as soon
as atari_floppy_init() released ataflop_probe_lock mutex.
As with commit 8b52d8be86 ("loop: reorder loop_exit"),
unregister_blkdev() needs to be called first in order to avoid calling
ataflop_alloc_disk() from ataflop_probe() after del_gendisk() from
atari_floppy_exit().
By relocating __register_blkdev() / unregister_blkdev() as explained above,
we can remove ataflop_probe_lock mutex, for probe function and __exit
function are serialized by major_names_lock mutex.

Since nvdimm/blk uses devm we just need to move the devm

to also provide a fix given del_gendisk() should not be

Nouveau does not currently support hot-unplugging, but it still makes
sense to switch from drm_dev_unregister() to drm_dev_unplug().
drm_dev_unplug() calls drm_dev_unregister() after marking the device as
unplugged, but only after any device critical sections are finished.
Since nouveau isn't using drm_dev_enter() and drm_dev_exit(), there are
no critical sections so this is nearly functionally equivalent. However,
the DRM layer does check to see if the device is unplugged, and if it is
returns appropriate error codes.
In the future nouveau can add critical sections in order to truly
support hot-unplugging.

The spec recommends that for transfer length larger than the max-single-cmd
attribute (bMAX_DATA_SIZE_FOR_HPB_SINGLE_CMD) it is possible to couple
pre-requests with the HPB-READ command. Being a recommendation, using
pre-requests can be perceived merely as a means of optimization. A common
practice was to send pre-requests for chunks within some interval, and
leave the READ10 untouched if larger.
Now that the pre-request flows have been removed, all the commands are
single commands. Properly handle this attribute and do not send HPB-READ
for transfer lengths larger than max-single-cmd.

The changes to issue the abort from the scmd->abort_work instead of the EH
thread introduced a problem if eh_deadline is used. If aborting the
command(s) is successful, and there are never any scmds added to the
shost->eh_cmd_q, there is no code path which will reset the ->last_reset
value back to zero.
The effect of this is that after a successful abort with no EH thread
activity, a subsequent timeout, perhaps a long time later, might
immediately be considered past a user-set eh_deadline time, and the host
will be reset with no attempt at recovery.
Fix this by resetting ->last_reset back to zero in scmd_eh_abort_handler()
if it is determined that the EH thread will not run to do this.
Thanks to Gopinath Marappan for investigating this problem.

These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

OMAP2 platform, another step in the eternal cleanup of that platform.
There are two new SoCs getting added: STMicroelectronics stm32mp13 and
Microchip lan966. Both fit into existing platforms and require minimal
changes here.
A couple of MAINTAINER file updates relate to those changes, and
update some file paths.

The code which constructs the modules for each engine present on the GPU
passes -1 for 'instance' on non-instanced engines, which affects how the
name for a sub-device is generated. This is then stored as 'instance 0'
in nvkm_subdev.inst, so code can potentially be shared with earlier GPUs
that only had a single instance of an engine.
However, GF100's CE constructor uses this value to calculate the address
of its falcon before it's translated, resulting in CE0 getting the wrong
address.
This slightly modifies the approach, always passing a valid instance for
engines that *can* have multiple copies, and having the code for earlier
GPUs explicitly ask for non-instanced name generation.

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worse scenario, could lead to heap overflows.
