xfs: fix reloading the last iunlink item
It's not a good idea to be trying to send bug fixes to the mailing list
while also trying to take a vacation. Dave sent some review comments
about the iunlink reloading patches, I changed them in djwong-dev, and
forgot to backport those changes to my -fixes tree.
As a result, the patch is missing some important pieces. Perhaps
manually copying code diffs between email and two separate git trees
is archaic and stupid^W^W^W^Wisn't really a good idea?

The iommu_suspend() syscore suspend callback is invoked with IRQ disabled.
Allocating memory with the GFP_KERNEL flag may re-enable IRQs during

Nathan reported that he was seeing the new warning in
setattr_copy_mgtime pop when starting podman containers. Overlayfs is
trying to set the atime and mtime via notify_change without also
setting the ctime.
POSIX states that when the atime and mtime are updated via utimes() that
we must also update the ctime to the current time. The situation with
overlayfs copy-up is analogies, so add ATTR_CTIME to the bitmask.
notify_change will fill in the value.

acpi_video_bus_add_notify_handler() could free video->input and
set it to NULL on failure, but this failure would be missed in its
caller acpi_video_bus_add(). As a result, when an error happens in
acpi_dev_install_notify_handler(), acpi_video_bus_add() would call
acpi_video_bus_remove_notify_handler(), where a potential NULL pointer
video->input is dereferenced in input_unregister_device().
Fix this by adding a return value check and adjusting the following
error handling code.

overlayfs copies the kiocb flags when it sets up a new kiocb to handle
a write, but it doesn't properly support dealing with the deferred
caller completions of the kiocb. This means it doesn't get the final
write completion value, and hence will complete the write with '0' as
the result.
We could support the caller completions in overlayfs, but for now let's
just disable them in the generated write kiocb.

Commit a4fdd9762272 ("iommu: Use flush queue capability") hid the
IOMMU_DOMAIN_DMA_FQ domain type from domain allocation. A check was
introduced in iommu_dma_init_domain() to fall back if not supported, but
this check runs too late: by that point, devices have been attached to
the IOMMU, and apple-dart's attach_dev() callback does not expect
IOMMU_DOMAIN_DMA_FQ domains.
Change the logic so the IOMMU_DOMAIN_DMA codepath is the default,
instead of explicitly enumerating all types.
Fixes an apple-dart regression in v6.5.

In mt8192/mt8186, there is only one MM IOMMU that supports 16GB iova
space, which is shared by display, vcodec and camera. These two SoC use
one pgtable and have not the flag SHARE_PGTABLE, we should also keep
share pgtable for this case.
In mtk_iommu_domain_finalise, MM IOMMU always share pgtable, thus remove
the flag SHARE_PGTABLE checking. Infra IOMMU always uses independent
pgtable.

Zen 4 systems running buggy microcode can hit a WARN_ON() in the PMI
handler, as shown below, several times while perf runs. A simple
`perf top` run is enough to render the system unusable:
WARNING: CPU: 18 PID: 20608 at arch/x86/events/amd/core.c:944 amd_pmu_v2_handle_irq+0x1be/0x2b0
This happens because the Performance Counter Global Status Register
(PerfCntGlobalStatus) has one or more bits set which are considered
reserved according to the "AMD64 Architecture Programmer’s Manual,
Volume 2: System Programming, 24593":
https://www.amd.com/system/files/TechDocs/24593.pdf
To make this less intrusive, warn just once if any reserved bit is set
and prompt the user to update the microcode. Also sanitize the value to
what the code is handling, so that the overflow events continue to be
handled for the number of counters that are known to be sane.
Going forward, the following microcode patch levels are recommended
for Zen 4 processors in order to avoid such issues with reserved bits:
Family=0x19 Model=0x11 Stepping=0x01: Patch=0x0a10113e
Family=0x19 Model=0x11 Stepping=0x02: Patch=0x0a10123e
Family=0x19 Model=0xa0 Stepping=0x01: Patch=0x0aa00116
Family=0x19 Model=0xa0 Stepping=0x02: Patch=0x0aa00212
Commit f2eb058afc57 ("linux-firmware: Update AMD cpu microcode") from
the linux-firmware tree has binaries that meet the minimum required
patch levels.

some readers no longer force #CLKREQ to low

But some platform maybe not implement complete ASPM?
it causes some platforms can not boot

Move the judgment (L1ss) to probe,

Lower layer device driver stop/wake TX by calling ieee80211_stop_queue()/
ieee80211_wake_queue() while hw scan. Sometimes hw scan and PTK rekey are
running in parallel, when M4 sent from wpa_supplicant arrive while the TX
queue is stopped, then the M4 will pending send, and then new key install
from wpa_supplicant. After TX queue wake up by lower layer device driver,
the M4 will be dropped by below call stack.
When key install started, the current key flag is set KEY_FLAG_TAINTED in
ieee80211_pairwise_rekey(), and then mac80211 wait key install complete by
lower layer device driver. Meanwhile ieee80211_tx_h_select_key() will return
TX_DROP for the M4 in step 12 below, and then ieee80211_free_txskb() called
by ieee80211_tx_dequeue(), so the M4 will not send and free, then the rekey
process failed becaue AP not receive M4. Please see details in steps below.
There are a interval between KEY_FLAG_TAINTED set for current key flag and
install key complete by lower layer device driver, the KEY_FLAG_TAINTED is
set in this interval, all packet including M4 will be dropped in this
interval, the interval is step 8~13 as below.
issue steps:
TX thread install key thread
1. stop_queue -idle-
2. sending M4 -idle-
3. M4 pending -idle-
4. -idle- starting install key from wpa_supplicant
5. -idle- =>ieee80211_key_replace()
6. -idle- =>ieee80211_pairwise_rekey() and set
currently key->flags |= KEY_FLAG_TAINTED
7. -idle- =>ieee80211_key_enable_hw_accel()
8. -idle- =>drv_set_key() and waiting key install
complete from lower layer device driver
9. wake_queue -waiting state-
10. re-sending M4 -waiting state-
11. =>ieee80211_tx_h_select_key() -waiting state-
12. drop M4 by KEY_FLAG_TAINTED -waiting state-
13. -idle- install key complete with success/fail
success: clear flag KEY_FLAG_TAINTED
fail: start disconnect
Hence add check in step 11 above to allow the EAPOL send out in the
interval. If lower layer device driver use the old key/cipher to encrypt
the M4, then AP received/decrypt M4 correctly, after M4 send out, lower
layer device driver install the new key/cipher to hardware and return
success.
If lower layer device driver use new key/cipher to send the M4, then AP
will/should drop the M4, then it is same result with this issue, AP will/
should kick out station as well as this issue.

On certain SATA controllers, softreset fails after wakeup from S2RAM with
the message "softreset failed (1st FIS failed)", sometimes resulting in
drives not being detected again. With the increased timeout, this issue
is avoided. Instead, "softreset failed (device not ready)" is now
logged 1-2 times; this later failure seems to cause fewer problems
however, and the drives are detected reliably once they've spun up and
the probe is retried.
The issue was observed with the primary SATA controller of the QNAP
TS-453B, which is an "Intel Corporation Celeron/Pentium Silver Processor
SATA Controller [8086:31e3] (rev 06)" integrated in the Celeron J4125 CPU,
and the following drives:
- Seagate IronWolf ST12000VN0008
- Seagate IronWolf ST8000NE0004
The SATA controller seems to be more relevant to this issue than the
drives, as the same drives are always detected reliably on the secondary
SATA controller on the same board (an ASMedia 106x) without any "softreset
failed" errors even without the increased timeout.

When ieee80211_key_link() is called by ieee80211_gtk_rekey_add()
but returns 0 due to KRACK protection (identical key reinstall),
ieee80211_gtk_rekey_add() will still return a pointer into the
key, in a potential use-after-free. This normally doesn't happen
since it's only called by iwlwifi in case of WoWLAN rekey offload
which has its own KRACK protection, but still better to fix, do
that by returning an error code and converting that to success on

During review of the patcheset that provided reloading of the incore
iunlink list, Dave made a few suggestions, and I updated the copy in my
dev tree. Unfortunately, I then got distracted by ... who even knows
what ... and forgot to backport those changes from my dev tree to my
release candidate branch. I then sent multiple pull requests with stale
patches, and that's what was merged into -rc3.
So.
This patch re-adds the use of an unlocked iunlink list check to
determine if we want to allocate the resources to recreate the incore
list. Since lost iunlinked inodes are supposed to be rare, this change
helps us avoid paying the transaction and AGF locking costs every time
we open any inode.
This also re-adds the shutdowns on failure, and re-applies the
restructuring of the inner loop in xfs_inode_reload_unlinked_bucket, and
re-adds a requested comment about the quotachecking code.
Retain the original RVB tag from Dave since there's no code change from
the last submission.

The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the
accounting was not accurate. It is suppose to show how many used

empty it would still show there were bytes used.
- Fix a bug in eventfs where reading a dynamic event directory (open)
and then creating a dynamic event that goes into that diretory screws
up the accounting.
On close, the newly created event dentry will get a "dput" without
ever having a "dget" done for it. The fix is to allocate an array on

"A collection of regression fixes, bug fixes, and some small cleanups
to the Compute Express Link code.
The regressions arrived in the v6.5 dev cycle and missed the v6.6
merge window due to my personal absences this cycle. The most
important fixes are for scenarios where the CXL subsystem fails to
parse valid region configurations established by platform firmware.
This is important because agreement between OS and BIOS on the CXL
configuration is fundamental to implementing "OS native" error
handling, i.e. address translation and component failure
identification.
Other important fixes are a driver load error when the BIOS lets the
Linux PCI core handle AER events, but not CXL memory errors.
The other fixex might have end user impact, but for now are only known
to trigger in our test/emulation environment.
Summary:
- Fix multiple scenarios where platform firmware defined regions fail
to be assembled by the CXL core.
- Fix a spurious driver-load failure on platforms that enable OS
native AER, but not OS native CXL error handling.
- Fix a regression detecting "poison" commands when "security"

attempting to read from the associated registers.
This same kexec issue is present with the imx8m SoCs that use the
imx8mm_soc_uid function (e.g. imx8mp). This requires the imx8mm_soc_uid
function to configure the OCOTP clock before accessing the associated

Commit 16c984524862 ("arm64: dts: imx8mp: don't initialize audio clocks

the intent is to force people to setup the audio PLL clocks per board
instead of having a common set of rates since not all boards may use
the various audio PLL clocks for audio devices.
This resulted in an incorrect clock rate when attempting to playback
audio, since the AUDIO_PLL2 wasn't set any longer. Fix this by
setting the AUDIO_PLL2 rate inside the SAI3 node since it's the SAI3
that needs it.

from CCM node") removed the Audio clocks from the main clock node, because
the intent is to force people to setup the audio PLL clocks per board
instead of having a common set of rates, since not all boards may use
the various audio PLL clocks in the same way.
Unfortunately, with this parenting removed, the SDMA2 and SDMA3
clocks were slowed to 24MHz because the SDMA2/3 clocks are controlled
via the audio_blk_ctrl which is clocked from IMX8MP_CLK_AUDIO_ROOT,
and that clock is enabled by pgc_audio.
Per the TRM, "The SDMA2/3 target frequency is 400MHz IPG and 400MHz
AHB, always 1:1 mode, to make sure there is enough throughput for all
the audio use cases."
Instead of cluttering the clock node, place the clock rate and parent
information into the pgc_audio node.
With the parenting and clock rates restored for IMX8MP_CLK_AUDIO_AHB,
and IMX8MP_CLK_AUDIO_AXI_SRC, it appears the SDMA2 and SDMA3 run at
400MHz again.

When the TSC_AUX MSR is virtualized, the TSC_AUX value is swap type "B"
within the VMSA. This means that the guest value is loaded on VMRUN and
the host value is restored from the host save area on #VMEXIT.
Since the value is restored on #VMEXIT, the KVM user return MSR support
for TSC_AUX can be replaced by populating the host save area with the
current host value of TSC_AUX. And, since TSC_AUX is not changed by Linux
post-boot, the host save area can be set once in svm_hardware_enable().
This eliminates the two WRMSR instructions associated with the user return
MSR support.

The checks for virtualizing TSC_AUX occur during the vCPU reset processing
path. However, at the time of initial vCPU reset processing, when the vCPU
is first created, not all of the guest CPUID information has been set. In
this case the RDTSCP and RDPID feature support for the guest is not in
place and so TSC_AUX virtualization is not established.
This continues for each vCPU created for the guest. On the first boot of
an AP, vCPU reset processing is executed as a result of an APIC INIT
event, this time with all of the guest CPUID information set, resulting
in TSC_AUX virtualization being enabled, but only for the APs. The BSP
always sees a TSC_AUX value of 0 which probably went unnoticed because,
at least for Linux, the BSP TSC_AUX value is 0.
Move the TSC_AUX virtualization enablement out of the init_vmcb() path and
into the vcpu_after_set_cpuid() path to allow for proper initialization of
the support after the guest CPUID information has been set.
With the TSC_AUX virtualization support now in the vcpu_set_after_cpuid()
path, the intercepts must be either cleared or set based on the guest
CPUID input.

Stop zapping invalidate TDP MMU roots via work queue now that KVM
preserves TDP MMU roots until they are explicitly invalidated. Zapping
roots asynchronously was effectively a workaround to avoid stalling a vCPU
for an extended during if a vCPU unloaded a root, which at the time
happened whenever the guest toggled CR0.WP (a frequent operation for some
guest kernels).
While a clever hack, zapping roots via an unbound worker had subtle,
unintended consequences on host scheduling, especially when zapping
multiple roots, e.g. as part of a memslot. Because the work of zapping a
root is no longer bound to the task that initiated the zap, things like
the CPU affinity and priority of the original task get lost. Losing the
affinity and priority can be especially problematic if unbound workqueues
aren't affined to a small number of CPUs, as zapping multiple roots can
cause KVM to heavily utilize the majority of CPUs in the system, *beyond*
the CPUs KVM is already using to run vCPUs.
When deleting a memslot via KVM_SET_USER_MEMORY_REGION, the async root
zap can result in KVM occupying all logical CPUs for ~8ms, and result in
high priority tasks not being scheduled in in a timely manner. In v5.15,
which doesn't preserve unloaded roots, the issues were even more noticeable
as KVM would zap roots more frequently and could occupy all CPUs for 50ms+.
Consuming all CPUs for an extended duration can lead to significant jitter
throughout the system, e.g. on ChromeOS with virtio-gpu, deleting memslots
is a semi-frequent operation as memslots are deleted and recreated with
different host virtual addresses to react to host GPU drivers allocating
and freeing GPU blobs. On ChromeOS, the jitter manifests as audio blips
during games due to the audio server's tasks not getting scheduled in
promptly, despite the tasks having a high realtime priority.
Deleting memslots isn't exactly a fast path and should be avoided when
possible, and ChromeOS is working towards utilizing MAP_FIXED to avoid the
memslot shenanigans, but KVM is squarely in the wrong. Not to mention
that removing the async zapping eliminates a non-trivial amount of
complexity.
Note, one of the subtle behaviors hidden behind the async zapping is that
KVM would zap invalidated roots only once (ignoring partial zaps from
things like mmu_notifier events). Preserve this behavior by adding a flag
to identify roots that are scheduled to be zapped versus roots that have
already been zapped but not yet freed.
Add a comment calling out why kvm_tdp_mmu_invalidate_all_roots() can
encounter invalid roots, as it's not at all obvious why zapping
invalidated roots shouldn't simply zap all invalid roots.
