The i_version field in the kernel has had different semantics over
the decades, but NFSv4 has certain expectations. Update the comments
in iversion.h to describe when the i_version must change.

There has been a fix we have been delaying for v6.2 due to lack of
early testing on linux-next. The commit has been sitting on linux-next
since December and testing has also been now a bit extensive by a few
developers. Since this is a fix which definitely will go to v6.3 it
should also apply to v6.2 so if there are any issues we pick them up
earlier rather than later. The fix fixes a regression since v5.3, prior
to me helping with module maintenance, however, the issue is real in
that in the worst case now can prevent boot.
We've discussed all possible corner cases [0] and at last do feel this is
ready for v6.2-rc6.

During a system boot, it can happen that the kernel receives a burst of
requests to insert the same module but loading it eventually fails
during its init call. For instance, udev can make a request to insert
a frequency module for each individual CPU when another frequency module
is already loaded which causes the init function of the new module to
return an error.
Since commit 6e6de3dee5 ("kernel/module.c: Only return -EEXIST for
modules that have finished loading"), the kernel waits for modules in
MODULE_STATE_GOING state to finish unloading before making another
attempt to load the same module.
This creates unnecessary work in the described scenario and delays the
boot. In the worst case, it can prevent udev from loading drivers for
other devices and might cause timeouts of services waiting on them and
subsequently a failed boot.
This patch attempts a different solution for the problem 6e6de3dee5
was trying to solve. Rather than waiting for the unloading to complete,
it returns a different error code (-EBUSY) for modules in the GOING
state. This should avoid the error situation that was described in
6e6de3dee5 (user space attempting to load a dependent module because
the -EEXIST error code would suggest to user space that the first module
had been loaded successfully), while avoiding the delay situation too.
This has been tested on linux-next since December 2022 and passes
all kmod selftests except test 0009 with module compression enabled
but it has been confirmed that this issue has existed and has gone
unnoticed since prior to this commit and can also be reproduced without
module compression with a simple usleep(5000000) on tools/modprobe.c [0].
These failures are caused by hitting the kernel mod_concurrent_max and can
happen either due to a self inflicted kernel module auto-loead DoS somehow
or on a system with large CPU count and each CPU count incorrectly triggering
many module auto-loads. Both of those issues need to be fixed in-kernel.

Commit f3bbac3247 ("ext4: deal with legacy signed xattr name hash
values") added a hashing function for the legacy case of having the
xattr hash calculated using a signed 'char' type. It left the unsigned
case alone, since it's all implicitly handled by the '-funsigned-char'
compiler option.
However, there's been some noise about back-porting it all into stable
kernels that lack the '-funsigned-char', so let's just make that at
least possible by making the whole 'this uses unsigned char' very
explicit in the code itself. Whether such a back-port is really
warranted or not, I'll leave to others, but at least together with this
change it is technically sensible.
Also, add a 'pr_warn_once()' for reporting the "hey, signedness for this
hash calculation has changed" issue. Hopefully it never triggers except
for that xfstests generic/454 test-case, but even if it does it's just
good information to have.
If for no other reason than "we can remove the legacy signed hash code
entirely if nobody ever sees the message any more".

When serializing and deserializing kvm_sregs, attributes of the segment
descriptors are stored by user space. For unusable segments,
vmx_segment_access_rights skips all attributes and sets them to 0.
This means we zero out the DPL (Descriptor Privilege Level) for unusable
entries.
Unusable segments are - contrary to their name - usable in 64bit mode and
are used by guests to for example create a linear map through the
NULL selector.
VMENTER checks if SS.DPL is correct depending on the CS segment type.
For types 9 (Execute Only) and 11 (Execute Read), CS.DPL must be equal to
SS.DPL [1].
We have seen real world guests setting CS to a usable segment with DPL=3
and SS to an unusable segment with DPL=3. Once we go through an sregs
get/set cycle, SS.DPL turns to 0. This causes the virtual machine to crash
reproducibly.
This commit changes the attribute logic to always preserve attributes for
unusable segments. According to [2] SS.DPL is always saved on VM exits,
regardless of the unusable bit so user space applications should have saved
the information on serialization correctly.
[3] specifies that besides SS.DPL the rest of the attributes of the
descriptors are undefined after VM entry if unusable bit is set. So, there
should be no harm in setting them all to the previous state.

Commit b2b0a5e978 switched from generic_writepages() to
filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to
replacing ->writepage() with ->writepages() and eventually eliminating
the former. Function gfs2_ail1_start_one() is called from
gfs2_log_flush(), our main function for flushing the filesystem log.
Unfortunately, at least as implemented today, ->writepage() and
->writepages() are entirely different operations for journaled data
inodes: while the former creates and submits transactions covering the
data to be written, the latter flushes dirty buffers out to disk.
With gfs2_ail1_start_one() now calling ->writepages(), we end up
creating filesystem transactions while we are in the course of a log
flush, which immediately deadlocks on the sdp->sd_log_flush_lock
semaphore.
Work around that by going back to how things used to work before commit
b2b0a5e978 for now; figuring out a superior solution will take time we
don't have available right now. However ...
Since the removal of generic_writepages() is imminent, open-code it
here. We're already inside a blk_start_plug() ... blk_finish_plug()
section here, so skip that part of the original generic_writepages().
This reverts commit b2b0a5e978.

The issue is around the poll race fix, and how it mistakenly also got
applied to multishot polling. Those don't need the race fix, and we
should not be doing any reissues for that case. Exhaustive test cases
were written and committed to the liburing regression suite for the

We potentially have old hashes of the xattr names generated on systems
with signed 'char' types. Now that everybody uses '-funsigned-char',
those hashes will no longer match.
This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.
Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

do_prlimit() adds the user-controlled resource value to a pointer that
will subsequently be dereferenced. In order to help prevent this
codepath from being used as a spectre "gadget" a barrier needs to be
added after checking the range.

To save the vgic LPI pending state with GICv4.1, the VPEs must all be
unmapped from the ITSs so that the sGIC caches can be flushed.
The opposite is done once the state is saved.
This is all done by using the activate/deactivate irqdomain callbacks
directly from the vgic code. Crutially, this is done without holding
the irqdesc lock for the interrupts that represent the VPE. And these
callbacks are changing the state of the irqdesc. What could possibly
go wrong?
If a doorbell fires while we are messing with the irqdesc state,
it will acquire the lock and change the interrupt state concurrently.
Since we don't hole the lock, curruption occurs in on the interrupt
state. Oh well.
While acquiring the lock would fix this (and this was Shanker's
initial approach), this is still a layering violation we could do
without. A better approach is actually to free the VPE interrupt,
do what we have to do, and re-request it.
It is more work, but this usually happens only once in the lifetime
of the VM and we don't really care about this sort of overhead.

Commit d77e59a8fc ("arm64: mte: Lock a page for MTE tag
initialisation") added a call to mte_clear_page_tags() in case a
prior mte_copy_tags_from_user() failed in order to avoid stale tags in
the guest page (it should have really been a separate commit).
Unfortunately, the argument passed to this function was the address of
the struct page rather than the actual page address. Fix this function
call.

A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.
A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

MAINTAINERS: Update the ACPICA development list address
Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
including:
- A regression fix for SDHCI controllers on Inforce 6540, and
another SDHCI fix on SM8350
- Reenable cluster idle on sm8250 after the the code fix is upstream
- multiple fixes for the QMP PHY binding, needing an incompatible
dt change
- The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
6P, to avoid instabilities caused by use of protected memory regions
- Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
clock error
- A couple of verdin-imx8mm DT fixes for audio playback support
- Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
- Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
eMMC CMD8 CRC error in HS400ES/HS400 mode
The remaining ARM and RISC-V platforms only have very few
smaller dts bugfixes this time:
- A fix for the SiFive unmatched board's PCI memory space
- A revert to fix a regression with GPIO on Marvell Armada
- A fix for the UART address on Marvell AC5
- Missing chip-select phandles for stm32 boards
- Selecting the correct clock for the sam9x60 memory controller
- Amlogic based Odroid-HC4 needs a revert to restore USB
functionality.
And finally, there are some minor code fixes:
- Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
firmware
- memory controller driver fixes for an OMAP regression and older bugs
on tegra, atmel and mvebu
- reset controller fixes for ti-sci and uniphier platforms
- ARM SCMI firmware fixes for a couple of rare corner cases
- Qualcomm platform driver fixes for incorrect error handling and a
backwards compatibility fix for the apr driver using older dtb
- NXP i.MX SoC driver fixes for HDMI output, error handling in the imx8
soc-id and missing reference counting on older cpuid code

...
The memory for llcc_driv_data is allocated by the LLCC driver. But when
it is passed as the private driver info to the EDAC core, it will get freed
during the qcom_edac driver release. So when the qcom_edac driver gets probed
again, it will try to use the freed data leading to the use-after-free bug.
Hence, do not pass llcc_driv_data as pvt_info but rather reference it
using the platform_data pointer in the qcom_edac driver.
