If the scrub process is sent a fatal signal while we're checking dquots,
the predicate for this will set the error code to -EINTR. Don't then
squash that into -ECANCELED, because the wrong errno turns up in the
trace output.

If the program calling online fsck is terminated with a fatal signal,
bail out to userspace by returning EINTR, not EAGAIN. EAGAIN is used by
scrubbers to indicate that we should try again with more resources
locked, and not to indicate that the operation was cancelled. The
miswiring is mostly harmless, but it shows up in the trace data.

Memory allocation usage is the same throughout online fsck -- we want
kernel memory, we have to be able to back out if we can't allocate
memory, and we don't want to spray dmesg with memory allocation failure
reports. Standardize the GFP flag usage and document these requirements.

Currently, the only way to lock an allocation group is to hold the AGI
and AGF buffers. If a repair needs to roll the transaction while
repairing some AG metadata, it maintains that lock by holding the two
buffers across the transaction roll and joins them afterwards.
However, repair is not like other parts of XFS that employ the bhold -
roll - bjoin sequence because it's possible that the AGI or AGF buffers
are not actually dirty before the roll. This presents two problems --
First, we need to redirty those buffers to keep them moving along in the
log to avoid pinning the log tail. Second, a clean buffer log item can
detach from the buffer. If this happens, the buffer type state is
discarded along with the bli and must be reattached before the next time
the buffer is logged. If it is not, the logging code will complain and
log recovery will not work properly.
An earlier version of this patch tried to fix the second problem by
re-setting the buffer type in the bli after joining the buffer to the
new transaction, but that looked weird and didn't solve the first
problem. Instead, solve both problems by logging the buffer before
rolling the transaction.

While scrubbing an allocation group, we don't need to hold the AGFL
buffer as part of the scrub context. All that is necessary to lock an
AG is to hold the AGI and AGF buffers, so fix all the existing users of
the AGFL buffer to grab them only when necessary.

While running the online fsck test suite, I noticed the following

This assertion triggers in xfs_dirattr_mark_sick when the caller passes
in a whichfork value that is neither of XFS_{DATA,ATTR}_FORK. The cause
of this is that xchk_directory_blocks only partially initializes the
xfs_da_args structure that is passed to xfs_dir2_isblock. If the data
fork is not correct, the XFS_IS_CORRUPT clause will trigger. My
development branch reports this failure to the health monitoring
subsystem, which accesses the uninitialized args->whichfork field,
leading the the assertion tripping. We really shouldn't be passing
random stack contents around, so the solution here is to force the
compiler to zero-initialize the struct.
Found by fuzzing u3.bmx[0].blockcount = middlebit on xfs/1554.

When we reserve a delalloc region in xfs_buffered_write_iomap_begin,
we mark the iomap as IOMAP_F_NEW so that the the write context
understands that it allocated the delalloc region.
If we then fail that buffered write, xfs_buffered_write_iomap_end()
checks for the IOMAP_F_NEW flag and if it is set, it punches out
the unused delalloc region that was allocated for the write.
The assumption this code makes is that all buffered write operations
that can allocate space are run under an exclusive lock (i_rwsem).
This is an invalid assumption: page faults in mmap()d regions call
through this same function pair to map the file range being faulted
and this runs only holding the inode->i_mapping->invalidate_lock in
shared mode.
IOWs, we can have races between page faults and write() calls that
fail the nested page cache write operation that result in data loss.
That is, the failing iomap_end call will punch out the data that
the other racing iomap iteration brought into the page cache. This
can be reproduced with generic/34[46] if we arbitrarily fail page
cache copy-in operations from write() syscalls.
Code analysis tells us that the iomap_page_mkwrite() function holds
the already instantiated and uptodate folio locked across the iomap
mapping iterations. Hence the folio cannot be removed from memory
whilst we are mapping the range it covers, and as such we do not
care if the mapping changes state underneath the iomap iteration
loop:
1. if the folio is not already dirty, there is no writeback races
possible.
2. if we allocated the mapping (delalloc or unwritten), the folio
cannot already be dirty. See #1.
3. If the folio is already dirty, it must be up to date. As we hold
it locked, it cannot be reclaimed from memory. Hence we always
have valid data in the page cache while iterating the mapping.
4. Valid data in the page cache can exist when the underlying
mapping is DELALLOC, UNWRITTEN or WRITTEN. Having the mapping
change from DELALLOC->UNWRITTEN or UNWRITTEN->WRITTEN does not
change the data in the page - it only affects actions if we are
initialising a new page. Hence #3 applies and we don't care
about these extent map transitions racing with
iomap_page_mkwrite().
5. iomap_page_mkwrite() checks for page invalidation races
(truncate, hole punch, etc) after it locks the folio. We also
hold the mapping->invalidation_lock here, and hence the mapping
cannot change due to extent removal operations while we are
iterating the folio.
As such, filesystems that don't use bufferheads will never fail
the iomap_folio_mkwrite_iter() operation on the current mapping,
regardless of whether the iomap should be considered stale.
Further, the range we are asked to iterate is limited to the range
inside EOF that the folio spans. Hence, for XFS, we will only map
the exact range we are asked for, and we will only do speculative
preallocation with delalloc if we are mapping a hole at the EOF
page. The iterator will consume the entire range of the folio that
is within EOF, and anything beyond the EOF block cannot be accessed.
We never need to truncate this post-EOF speculative prealloc away in
the context of the iomap_page_mkwrite() iterator because if it
remains unused we'll remove it when the last reference to the inode
goes away.
Hence we don't actually need an .iomap_end() cleanup/error handling
path at all for iomap_page_mkwrite() for XFS. This means we can
separate the page fault processing from the complexity of the
.iomap_end() processing in the buffered write path. This also means
that the buffered write path will also be able to take the
mapping->invalidate_lock as necessary.

1:1 memory-device-to-region associations.
- Fix a memory leak for cxl_region objects when regions with active
targets are deleted
- Fix assignment of NUMA nodes to CXL regions by CFMWS (CXL Window)
emulated proximity domains.
- Fix region creation failure for switch attached devices downstream
of a single-port host-bridge

This reverts commit 54cc3dbfc10dc3db7cb1cf49aee4477a8398fbde.
Zev Weiss reports that the reverted patch may cause a regulator
undercount. Here is his report:
... having regulator-dummy set as a supply on my PMBus regulators
(instead of having them as their own top-level regulators without
an upstream supply) leads to enable-count underflow errors when
disabling them:
# echo 0 > /sys/bus/platform/devices/efuse01/state

[ 906.100563] Failed to disable vout: -EINVAL
[ 136.992676] reg-userspace-consumer efuse01: Failed to configure state: -22
Zev reports that reverting the patch fixes the problem. So let's do that
for now.

Available sensors are enumerated and reported by the SCMI platform server
using a 16bit identification number; not all such sensors are of a type
supported by hwmon subsystem and, among the supported ones, only a subset
could be temperature sensors that have to be registered with the Thermal
Framework.
Potential clashes between hwmon channels indexes and the underlying real
sensors IDs do not play well with the hwmon<-->thermal bridge automatic
registration routines and could need a sensible number of fake dummy
sensors to be made up in order to keep indexes and IDs in sync.
Avoid to use the hwmon<-->thermal bridge dropping the HWMON_C_REGISTER_TZ
attribute and instead explicit register temperature sensors directly with
the Thermal Framework.

At region creation time the next region-id is atomically cached so that
there is predictability of region device names. If that region is
destroyed and then a new one is created the region id increments. That
ends up looking like a memory leak, or is otherwise surprising that
identifiers roll forward even after destroying all previously created
regions.
Try to reuse rather than free old region ids at region release time.
While this fixes a cosmetic issue, the needlessly advancing memory
region-id gives the appearance of a memory leak, hence the "Fixes" tag,
but no "Cc: stable" tag.

When programming port decode targets, the algorithm wants to ensure that
two devices are compatible to be programmed as peers beneath a given
port. A compatible peer is a target that shares the same dport, and
where that target's interleave position also routes it to the same
dport. Compatibility is determined by the device's interleave position
being >= to distance. For example, if a given dport can only map every
Nth position then positions less than N away from the last target
programmed are incompatible.
The @distance for the host-bridge's cxl_port in a simple dual-ported
host-bridge configuration with 2 direct-attached devices is 1, i.e. An
x2 region divided by 2 dports to reach 2 region targets.
An x4 region under an x2 host-bridge would need 2 intervening switches
where the @distance at the host bridge level is 2 (x4 region divided by
2 switches to reach 4 devices).
However, the distance between peers underneath a single ported
host-bridge is always zero because there is no limit to the number of
devices that can be mapped. In other words, there are no decoders to
program in a passthrough, all descendants are mapped and distance only
starts matters for the intervening descendant ports of the passthrough
port.
Add tracking for the number of dports mapped to a port, and use that to
detect the passthrough case for calculating @distance.

When a cxl_nvdimm object goes through a ->remove() event (device
physically removed, nvdimm-bridge disabled, or nvdimm device disabled),
then any associated regions must also be disabled. As highlighted by the
cxl-create-region.sh test [1], a single device may host multiple
regions, but the driver was only tracking one region at a time. This
leads to a situation where only the last enabled region per nvdimm
device is cleaned up properly. Other regions are leaked, and this also
causes cxl_memdev reference leaks.
Fix the tracking by allowing cxl_nvdimm objects to track multiple region
associations.

When a region is deleted any targets that have been previously assigned
to that region hold references to it. Trigger those references to
drop by detaching all targets at unregister_region() time.
Otherwise that region object will leak as userspace has lost the ability

Pull xfs fixes from Darrick Wong:
"Dave and I had thought that this would be a very quiet cycle, but we
thought wrong.
At first there were the usual trickle of minor bugfixes, but then
Zorro pulled -rc1 and noticed complaints about the stronger memcpy
checks w.r.t. flex arrays.
Analyzing how to fix that revealed a bunch of validation gaps in
validating ondisk log items during recovery, and then a customer hit
an infinite loop in the refcounting code on a corrupt filesystem.
So. This largeish batch of fixes addresses all those problems, I hope.
Summary:
- Fix a UAF bug during log recovery
- Fix memory leaks when mount fails
- Detect corrupt bestfree information in a directory block
- Fix incorrect return value type for the dax page fault handlers
- Fix fortify complaints about memcpy of xfs log item objects
- Strengthen inadequate validation of recovered log items
- Fix incorrectly declared flex array in EFI log item structs
- Log corrupt log items for debugging purposes
- Fix infinite loop problems in the refcount code if the refcount
btree node block keys are corrupt
- Fix infinite loop problems in the refcount code if the refcount
btree records suffer MSB bitflips
- Add more sanity checking to continued defer ops to prevent
overflows from one AG to the next or off EOFS"

Pull drm fixes from Dave Airlie:
"This is the weekly fixes for rc4. Misc fixes across rockchip, imx,
amdgpu and i915.
The biggest change is for amdkfd where the trap handler needs an
updated fw from a header which makes it a bit larger. I hadn't noticed
this particular file before so I'm going to figure out what the magic
is for, but the fix should be fine for now.
amdgpu:
- DCN 3.1.4 fixes
- DCN 3.2.x fixes
- GC 11.x fixes
- Virtual display fix
- Fail suspend if resources can't be evicted
- SR-IOV fix
- Display PSR fix
amdkfd:
- Fix possible NULL pointer deref
- GC 11.x trap handler fix
i915:
- Add locking around DKL PHY register accesses
- Stop abusing swiotlb_max_segment
- Filter out invalid outputs more sensibly
- Setup DDC fully before output init
- Simplify intel_panel_add_edid_alt_fixed_modes()
- Grab mode_config.mutex during LVDS init to avoid WARNs
rockchip:
- fix probing issues
- fix framebuffer without iommu
- fix vop selection
- fix NULL ptr access
imx:
- Fix Kconfig
- fix mode_valid function"
