"For two kernel releases now kernel/sysctl.c has been being cleaned up
slowly, since the tables were grossly long, sprinkled with tons of

This tree was put together to help try to avoid conflicts with these

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
"This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which is
the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of
the mach/*.h headers to allow the platform to be part of a generic
ARMv4/v5 multiplatform kernel.
The last bit that enables this support is still missing here while we
wait for some last dependencies to make it into the mainline kernel
through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets
completed here along with a few additional cleanup. At the same time,
the s3c24xx and s3c64xx are now deprecated and expected to get removed
in the future.
The PXA and OMAP1 bits are in a separate branch because of
dependencies. Once both branches are merged, only the three Intel
StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
need separate kernels, and there are no plans to include these"

- Renesas RZ/G2UL (R9A07G043) is the single-core version of the
RZ/G2L general-purpose MPU.
- Renesas RZ/V2M (R9A09G011) is a smart camera SoC
- Renesas R-Car V4H (R8A779G0) is an automotive chip with Cortex-A76
cores and deep learning accerlation.
- Broadcom BCM47622 is a new broadband SoC based on a quad Cortex-A7
and dual Wifi-6.
- Corstone1000 is a generic platform from Arm that is used for
designing custom SoCs, the support for now is for the Fixed Virtual
Platform emulation for it.
- Mediatek MT8195 (Kompanio 1200) is a high-end consumer chip used in
upcoming Chromebooks.
- NXP i.MXRT1050 is a Cortex-M7 based microcontroller, the first
MMU-less SoC to be added in a while
New machines based on already supported SoCs this time are mainly for
32-bit platforms and include:
- Two wireless routers based on Broadcom bcm4708
- 30 new boards based on NXP i.MX6, i.MX7 and i.MX8 families, mostly
for the industrial embedded market, and on NXP LS1021A based IOT
board.
- Two ethernet switches based on Microchip LAN966
- Eight Qualcomm Snapdragon based machines, including a smartwatch, a
Chromebook board and some phones
- Another phone based on the old ST-Ericsson Ux500 platform
- Seven STM32MP1 based boards
- Four single-board computers based on Rockchip RK3566/RK3568"

locking/lockref: Use try_cmpxchg64 in CMPXCHG_LOOP macro
Use try_cmpxchg64 instead of cmpxchg64 in CMPXCHG_LOOP macro.
x86 CMPXCHG instruction returns success in ZF flag, so this
change saves a compare after cmpxchg (and related move instruction
in front of cmpxchg). The main loop of lockref_get improves from:

Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Dave Chinner:
"This is a big update with lots of new code. The summary below them
all, so I'll just touch on teh higlights. The two main new features
are Large Extent Counts and Logged Attribute Replay - these are two
new foundational features that we are building more complex future
features on top of.
For upcoming functionality, we need to be able to store hundreds of
millions of xattrs per inode. The Large Extent Count feature removes
the limits that prevent this scale of xattr storage, and while we were
modifying the on disk extent count format we also increased the number
of data extents we support per inode from 2^32 to 2^47.
We also need to be able to modify xattrs as part of larger atomic
transactions rather than as standalone transactions. The Logged
Attribute Replay feature introduces the infrastructure that allows us
to use intents to record the attribute modifications in the journal
before we start them, hence allowing other atomic transactions to log
attribute modification intents and then defer the actual modification
to later. If we then crash, log recovery then guarantees that the
attribute is replayed in the context of the atomic transaction that
logged the intent.
A significant chunk of the commits in this merge are for the base
attribute replay functionality along with fixes, improvements and
cleanups related to this new functioanlity. Allison deserves a big
round of thanks for her ongoing work to get this functionality into
XFS.
There are also many other smaller changes and improvements, so overall
this is one of the bigger XFS merge requests in some time.
I will be following up next week with another smaller pull request -
we already have another round of fixes and improvements to the logged
attribute replay functionality just about ready to go. They'll soak
and test over the next week, and I'll send a pull request for them
near the end of the merge window.
Summary:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents
and 2^32 attribute extents, allowing us to scale beyond 4 billion
data extents to billions of xattrs per inode.
- conversion of various flags fields to be consistently declared as
unsigned bit fields.
- improvements to realtime extent accounting and converts them to
per-cpu counters to match all the other block and inode accounting.
- reworks core log formatting code to reduce iterations, have a
shorter, cleaner fast path and generally be easier to understand
and maintain.
- improvements to rmap btree searches that reduce overhead by up to
30% resulting in xfs_scrub runtime reductions of 15%.
- improvements to reflink that remove the size limitations in
remapping operations and greatly reduce the size of transaction
reservations.
- reworks the minimum log size calculations to allow us to change
transaction reservations without changing the minimum supported log
size.
- removal of quota warning support as it has never been used on
Linux.
- intent whiteouts to allow us to cancel intents that are completed
entirely in memory rather than having use CPU and disk bandwidth
formatting and writing them into the journal when it is not
necessary. This makes rmap, reflink and extent freeing slightly
more efficient, but provides massive improvements for....
- Logged Attribute Replay feature support. This is a fundamental
change to the way we modify attributes, laying the foundation for
future integration of attribute modifications as part of other
atomic transactional operations the filesystem performs.
- Lots of cleanups and fixes for the logged attribute replay
functionality"

selftests: vm: check numa_available() before operating "merge_across_nodes" in ksm_tests
Patch series "selftests: vm: a few fixup patches".
This series contains three fixup patches for vm selftests. They are
independent. Please see the patches.
This patch (of 3):
Currently, ksm_tests operates "merge_across_nodes" with NUMA either
enabled or disabled. In a system with NUMA disabled, these operations
will fail and output a misleading report given "merge_across_nodes" does
not exist in sysfs:
----------------------------
running ./ksm_tests -M -p 10
----------------------------
f /sys/kernel/mm/ksm/merge_across_nodes
fopen: No such file or directory
Cannot save default tunables
[FAIL]
----------------------
So check numa_available() before those operations to skip them if NUMA is
disabled.
Introduce process_mrelease syscall sanity tests which include tests
which expect to fail:
- process_mrelease with invalid pidfd and flags inputs
- process_mrelease on a live process with no pending signals
and valid process_mrelease usage which is expected to succeed. Because
process_mrelease has to be used against a process with a pending SIGKILL,
it's possible that the process exits before process_mrelease gets called.
In such cases we retry the test with a victim that allocates twice more
memory up to 1GB. This would require the victim process to spend more
time during exit and process_mrelease has a better chance of catching the
process before it exits and succeeding.
On success the test reports the amount of memory the child had to allocate
for reaping to succeed. Sample output:
$ mrelease_test
Success reaping a child with 1MB of memory allocations
On failure the test reports the failure. Sample outputs:
$ mrelease_test
All process_mrelease attempts failed!
Its premise was that cgroup reclaim cares about freeing memory inside the
cgroup, and demotion just moves them around within the cgroup limit.
Hence, pages from toptier nodes should be reclaimed directly.
However, with NUMA balancing now doing tier promotions, demotion is part
of the page aging process. Global reclaim demotes the coldest toptier
pages to secondary memory, where their life continues and from which they
have a chance to get promoted back. Essentially, tiered memory systems
have an LRU order that spans multiple nodes.
When cgroup reclaims pages coming off the toptier directly, there can be
colder pages on lower tier nodes that were demoted by global reclaim.
This is an aging inversion, not unlike if cgroups were to reclaim directly
from the active lists while there are inactive pages.
Proactive reclaim is another factor. The goal of that it is to offload
colder pages from expensive RAM to cheaper storage. When lower tier
memory is available as an intermediate layer, we want offloading to take
advantage of it instead of bypassing to storage.
Revert the patch so that cgroups respect the LRU order spanning the memory
hierarchy.
Of note is a specific undercommit scenario, where all cgroup limits in the
system add up to <= available toptier memory. In that case, shuffling
pages out to lower tiers first to reclaim them from there is inefficient.
This is something could be optimized/short-circuited later on (although
care must be taken not to accidentally recreate the aging inversion).
Let's ensure correctness first.

mm: fix a potential infinite loop in start_isolate_page_range()
In isolate_single_pageblock() called by start_isolate_page_range(), there
are some pageblock isolation issues causing a potential infinite loop when
isolating a page range. This is reported by Qian Cai.
1. the pageblock was isolated by just changing pageblock migratetype
without checking unmovable pages. Calling set_migratetype_isolate() to
isolate pageblock properly.
2. an off-by-one error caused migrating pages unnecessarily, since the page
is not crossing pageblock boundary.
3. migrating a compound page across pageblock boundary then splitting the
free page later has a small race window that the free page might be
allocated again, so that the code will try again, causing an potential
infinite loop. Temporarily set the to-be-migrated page's pageblock to
MIGRATE_ISOLATE to prevent that and bail out early if no free page is
found after page migration.
An additional fix to split_free_page() aims to avoid crashing in
__free_one_page(). When the free page is split at the specified
split_pfn_offset, free_page_order should check both the first bit of
free_page_pfn and the last bit of split_pfn_offset and use the smaller
one. For example, if free_page_pfn=0x10000, split_pfn_offset=0xc000,
free_page_order should first be 0x8000 then 0x4000, instead of 0x4000 then
0x8000, which the original algorithm did.

Pull printk updates from Petr Mladek:
- Offload writing printk() messages on consoles to per-console
kthreads.
It prevents soft-lockups when an extensive amount of messages is
printed. It was observed, for example, during boot of large systems
with a lot of peripherals like disks or network interfaces.
It prevents live-lockups that were observed, for example, when
messages about allocation failures were reported and a CPU handled
consoles instead of reclaiming the memory. It was hard to solve even
with rate limiting because it would need to take into account the
amount of messages and the speed of all consoles.
It is a must to have for real time. Otherwise, any printk() might
break latency guarantees.
The per-console kthreads allow to handle each console on its own
speed. Slow consoles do not longer slow down faster ones. And
printk() does not longer unpredictably slows down various code paths.
There are situations when the kthreads are either not available or
not reliable, for example, early boot, suspend, or panic. In these
situations, printk() uses the legacy mode and tries to handle
consoles immediately.

KVM: x86: Fix the intel_pt PMI handling wrongly considered from guest
When kernel handles the vm-exit caused by external interrupts and NMI,
it always sets kvm_intr_type to tell if it's dealing an IRQ or NMI. For
the PMI scenario, it could be IRQ or NMI.
However, intel_pt PMIs are only generated for HARDWARE perf events, and
HARDWARE events are always configured to generate NMIs. Use
kvm_handling_nmi_from_guest() to precisely identify if the intel_pt PMI
came from the guest; this avoids false positives if an intel_pt PMI/NMI

KVM: x86: avoid calling x86 emulator without a decoded instruction
Whenever x86_decode_emulated_instruction() detects a breakpoint, it
returns the value that kvm_vcpu_check_breakpoint() writes into its
pass-by-reference second argument. Unfortunately this is completely
bogus because the expected outcome of x86_decode_emulated_instruction
is an EMULATION_* value.
Then, if kvm_vcpu_check_breakpoint() does "*r = 0" (corresponding to
a KVM_EXIT_DEBUG userspace exit), it is misunderstood as EMULATION_OK
and x86_emulate_instruction() is called without having decoded the
instruction. This causes various havoc from running with a stale
emulation context.
The fix is to move the call to kvm_vcpu_check_breakpoint() where it was
before commit b0e4289dad91 ("KVM: x86: Factor out x86 instruction
emulation with decoding") introduced x86_decode_emulated_instruction().
The other caller of the function does not need breakpoint checks,
because it is invoked as part of a vmexit and the processor has already
checked those before executing the instruction that #GP'd.
This fixes CVE-2022-1852.

x86/fpu: KVM: Set the base guest FPU uABI size to sizeof(struct kvm_xsave)
Set the starting uABI size of KVM's guest FPU to 'struct kvm_xsave',
i.e. to KVM's historical uABI size. When saving FPU state for usersapce,
KVM (well, now the FPU) sets the FP+SSE bits in the XSAVE header even if
the host doesn't support XSAVE. Setting the XSAVE header allows the VM
to be migrated to a host that does support XSAVE without the new host
having to handle FPU state that may or may not be compatible with XSAVE.
Setting the uABI size to the host's default size results in out-of-bounds
writes (setting the FP+SSE bits) and data corruption (that is thankfully
caught by KASAN) when running on hosts without XSAVE, e.g. on Core2 CPUs.
WARN if the default size is larger than KVM's historical uABI size; all
features that can push the FPU size beyond the historical size must be
opt-in.

"There's a couple of corrections sent in by Andreas for some accounting
errors.
The biggest change this time around is that writeback errors longer

This brings XFS (and gfs2/zonefs) behavior in line with every other
Linux filesystem driver, and fixes some UAF bugs that only cropped up
after willy turned on multipage folios for XFS in 5.18-rc1.
Regrettably, it took all the way to the end of the 5.18 cycle to find
the source of these bugs and reach a consensus that XFS' writeback
failure behavior from 20 years ago is no longer necessary.
Summary:
- Fix a couple of accounting errors in the buffered io code.
- Discontinue the practice of marking folios !uptodate and
invalidating them when writeback fails.

Pull erofs (and fscache) updates from Gao Xiang:
"After working on it on the mailing list for more than half a year, we
finally form 'erofs over fscache' feature into shape. Hopefully it
could bring more possibility to the communities.
The story mainly started from a new project what we called "RAFS v6" [1]
for Nydus image service almost a year ago, which enhances EROFS to be
a new form of one bootstrap (which includes metadata representing the
whole fs tree) + several data-deduplicated content addressable blobs
(actually treated as multiple devices). Each blob can represent one
container image layer but not quite exactly since all new data can be
fully existed in the previous blobs so no need to introduce another
new blob.
It is actually not a new idea (at least on my side it's much like a
simpilied casync [2] for now) and has many benefits over per-file
blobs or some other exist ways since typically each RAFS v6 image only
has dozens of device blobs instead of thousands of per-file blobs.
It's easy to be signed with user keys as a golden image, transfered
untouchedly with minimal overhead over the network, kept in some type
of storage conveniently, and run with (optional) runtime verification
but without involving too many irrelevant features crossing the system
beyond EROFS itself. At least it's our final goal and we're keeping
working on it. There was also a good summary of this approach from the
casync author [3].
Regardless further optimizations, this work is almost done in the
previous Linux release cycles. In this round, we'd like to introduce
on-demand load for EROFS with the fscache/cachefiles infrastructure,
considering the following advantages:
- Introduce new file-based backend to EROFS. Although each image only
contains dozens of blobs but in densely-deployed runC host for
example, there could still be massive blobs on a machine, which is
messy if each blob is treated as a device. In contrast, fscache and
cachefiles are really great interfaces for us to make them work.
- Introduce on-demand load to fscache and EROFS. Previously, fscache
is mainly used to caching network-likewise filesystems, now it can
support on-demand downloading for local fses too with the exact
localfs on-disk format. It has many advantages which we're been
described in the latest patchset cover letter [4]. In addition to
that, most importantly, the cached data is still stored in the
original local fs on-disk format so that it's still the one signed
with private keys but only could be partially available. Users can
fully trust it during running. Later, users can also back up
cachefiles easily to another machine.
- More reliable on-demand approach in principle. After data is all
available locally, user daemon can be no longer online in some use
cases, which helps daemon crash recovery (filesystems can still in
service) and hot-upgrade (user daemon can be upgraded more
frequently due to new features or protocols introduced.)
- Other format can also be converted to EROFS filesystem format over
the internet on the fly with the new on-demand load feature and
mounted. That is entirely possible with on-demand load feature as
long as such archive format metadata can be fetched in advance like
stargz.
In addition, although currently our target user is Nydus image service [5],
but laterly, it can be used for other use cases like on-demand system
booting, etc. As for the fscache on-demand load feature itself,
strictly it can be used for other local fses too. Laterly we could
promote most code to the iomap infrastructure and also enhance it in
the read-write way if other local fses are interested.
Thanks David Howells for taking so much time and patience on this
these months, many thanks with great respect here again! Thanks Jeffle
for working on this feature and Xin Yin from Bytedance for
asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
Yan Song for testing, much appeciated. We're also exploring more
possibly over fscache cache management over FSDAX for secure
containers and working on more improvements and useful features for
fscache, cachefiles, and on-demand load.
In addition to "erofs over fscache", NFS export and idmapped mount are
also completed in this cycle for container use cases as well.
Summary:
- Add erofs on-demand load support over fscache
- Support NFS export for erofs
- Support idmapped mounts for erofs
- Don't prompt for risk any more when using big pcluster
- Fix buffer copy overflow of ztailpacking feature

Pull fs idmapping updates from Christian Brauner:
"This contains two minor updates:
- An update to the idmapping documentation by Rodrigo making it
easier to understand that we first introduce several use-cases that
fail without idmapped mounts simply to explain how they can be
handled with idmapped mounts.
- When changing a mount's idmapping we now hold writers to make it
more robust.
This is similar to turning a mount ro with the difference that in
contrast to turning a mount ro changing the idmapping can only ever
be done once while a mount can transition between ro and rw as much
as it wants.
The vfs layer itself takes care to retrieve the idmapping of a
mount once ensuring that the idmapping used for vfs permission
checking is identical to the idmapping passed down to the
filesystem. All filesystems with FS_ALLOW_IDMAP raised take the
same precautions as the vfs in code-paths that are outside of
direct control of the vfs such as ioctl()s.
However, holding writers makes this more robust and predictable for
both the kernel and userspace.
This is a minor user-visible change. But it is extremely unlikely
to matter. The caller must've created a detached mount via
OPEN_TREE_CLONE and then handed that O_PATH fd to another process
or thread which then must've gotten a writable fd for that mount
and started creating files in there while the caller is still
changing mount properties. While not impossible it will be an
extremely rare corner-case and should in general be considered a
bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC
or MOUNT_ATTR_NODEV while allowing someone else to perform lookups
or exec'ing in parallel by handing them a copy of the
OPEN_TREE_CLONE fd or another fd beneath that mount.
I've pinged all major users of idmapped mounts pointing out this
change and none of them have active writers on a mount while still
changing mount properties. It would've been strange if they did.
The rest and majority of the work will be coming through the overlayfs
tree this cycle. In addition to overlayfs this cycle should also see
support for idmapped mounts on erofs as I've acked a patch to this
effect a little while ago"

move things along we are adding a pause when the knobs are used to
help make the deprecation more noticeable in case anyone is still
using these hacks in the shadows.

when anonymous inodes are involved. This should make writing policy
easier when anonymous inodes are involved.
