James Wang has reproduced it stably on the latest 4.19 LTS.
After some debugging, we finally proved that it's due to ftrace

commit b220c049d519 ("tracing: Check length before giving out
the filter buffer") adds length check to protect trace data
overflow introduced in 0fc1b09ff1ff, seems that this fix can't prevent
overflow entirely, the length check should also take the sizeof
entry->array[0] into account, since this array[0] is filled the
length of trace data and occupy addtional space and risk overflow.

It was reported that a bug on arm64 caused a bad ip address to be used for
updating into a nop in ftrace_init(), but the error path (rightfully)
returned -EINVAL and not -EFAULT, as the bug caused more than one error to
occur. But because -EINVAL was returned, the ftrace_bug() tried to report
what was at the location of the ip address, and read it directly. This
caused the machine to panic, as the ip was not pointing to a valid memory
address.
Instead, read the ip address with copy_from_kernel_nofault() to safely
access the memory, and if it faults, report that the address faulted,
otherwise report what was in that location.

Allow creating FDB steering rules only when in switchdev mode.

FDB entries is when it manages the eswitch. This is only possible in

Update CP_PROTECT register programming based on downstream.
A6XX_PROTECT_RW is renamed to A6XX_PROTECT_NORDWR to make things aligned
and also be more clear about what it does.
Note that this required switching to use the CP_ALWAYS_ON_COUNTER as the
GMU counter is not accessible from the cmdstream. Which also means
using the CPU counter for the msm_gpu_submit_flush() tracepoint (as
catapult depends on being able to compare this to the start/end values
captured in cmdstream). This may need to be revisited when IFPC is
enabled.
Also, compared to downstream, this opens up CP_PERFCTR_CP_SEL as the
userspace performance tooling (fdperf and pps-producer) expect to be
able to configure the CP counters.

I met a gpu addr bug recently and the kernel log
tells me the pc is memcpy/memset and link register is
radeon_uvd_resume.
As we know, in some architectures, optimized memcpy/memset
may not work well on device memory. Trival memcpy_toio/memset_io
can fix this problem.
BTW, amdgpu has already done it in:
commit ba0b2275a678 ("drm/amdgpu: use memcpy_to/fromio for UVD fw upload"),
that's why it has no this issue on the same gpu and platform.

Use the __string() machinery provided by the tracing subystem to make a
copy of the string literals consumed by the "nested VM-Enter failed"
tracepoint. A complete copy is necessary to ensure that the tracepoint
can't outlive the data/memory it consumes and deference stale memory.
Because the tracepoint itself is defined by kvm, if kvm-intel and/or
kvm-amd are built as modules, the memory holding the string literals
defined by the vendor modules will be freed when the module is unloaded,
whereas the tracepoint and its data in the ring buffer will live until
kvm is unloaded (or "indefinitely" if kvm is built-in).
This bug has existed since the tracepoint was added, but was recently
exposed by a new check in tracing to detect exactly this type of bug.

Until commit 39fe2fc96694 ("selftests: kvm: make allocation of extra
memory take effect", 2021-05-27), parameter extra_mem_pages was used
only to calculate the page table size for all the memory chunks,
because real memory allocation happened with calls of
vm_userspace_mem_region_add() after vm_create_default().
Commit 39fe2fc96694 however changed the meaning of extra_mem_pages to
the size of memory slot 0. This makes the memory allocation more
flexible, but makes it harder to account for the number of
pages needed for the page tables. For example, memslot_perf_test
has a small amount of memory in slot 0 but a lot in other slots,
and adding that memory twice (both in slot 0 and with later
calls to vm_userspace_mem_region_add()) causes an error that
was fixed in commit 000ac4295339 ("selftests: kvm: fix overlapping
addresses in memslot_perf_test", 2021-05-29)
Since both uses are sensible, add a new parameter slot0_mem_pages
to vm_create_with_vcpus() and some comments to clarify the meaning of
slot0_mem_pages and extra_mem_pages. With this change,
memslot_perf_test can go back to passing the number of memory
pages as extra_mem_pages.

Commit bfb819ea20ce ("proc: Check /proc/$pid/attr/ writes against file opener")
tried to make sure that there could not be a confusion between the opener of
a /proc/$pid/attr/ file and the writer. It used struct cred to make sure
the privileges didn't change. However, there were existing cases where a more
privileged thread was passing the opened fd to a differently privileged thread
(during container setup). Instead, use mm_struct to track whether the opener
and writer are still the same process. (This is what several other proc files
already do, though for different reasons.)

In record_steal_time(), st->preempted is read twice, and

When computing the access permissions of a shadow page, use the effective
permissions of the walk up to that point, i.e. the logic AND of its parents'
permissions. Two guest PxE entries that point at the same table gfn need to
be shadowed with different shadow pages if their parents' permissions are
different. KVM currently uses the effective permissions of the last
non-leaf entry for all non-leaf entries. Because all non-leaf SPTEs have
full ("uwx") permissions, and the effective permissions are recorded only
in role.access and merged into the leaves, this can lead to incorrect
reuse of a shadow page and eventually to a missing guest protection page
fault.
For example, here is a shared pagetable:
pgd[] pud[] pmd[] virtual address pointers
/->pmd1(u--)->pte1(uw-)->page1 <- ptr1 (u--)
/->pud1(uw-)--->pmd2(uw-)->pte2(uw-)->page2 <- ptr2 (uw-)
pgd-| (shared pmd[] as above)
\->pud2(u--)--->pmd1(u--)->pte1(uw-)->page1 <- ptr3 (u--)
\->pmd2(uw-)->pte2(uw-)->page2 <- ptr4 (u--)
pud1 and pud2 point to the same pmd table, so:
- ptr1 and ptr3 points to the same page.
- ptr2 and ptr4 points to the same page.
(pud1 and pud2 here are pud entries, while pmd1 and pmd2 here are pmd entries)
- First, the guest reads from ptr1 first and KVM prepares a shadow
page table with role.access=u--, from ptr1's pud1 and ptr1's pmd1.
"u--" comes from the effective permissions of pgd, pud1 and
pmd1, which are stored in pt->access. "u--" is used also to get
the pagetable for pud1, instead of "uw-".
- Then the guest writes to ptr2 and KVM reuses pud1 which is present.
The hypervisor set up a shadow page for ptr2 with pt->access is "uw-"
even though the pud1 pmd (because of the incorrect argument to
kvm_mmu_get_page in the previous step) has role.access="u--".
- Then the guest reads from ptr3. The hypervisor reuses pud1's
shadow pmd for pud2, because both use "u--" for their permissions.
Thus, the shadow pmd already includes entries for both pmd1 and pmd2.
- At last, the guest writes to ptr4. This causes no vmexit or pagefault,
because pud1's shadow page structures included an "uw-" page even though
its role.access was "u--".
Any kind of shared pagetable might have the similar problem when in
virtual machine without TDP enabled if the permissions are different
from different ancestors.
In order to fix the problem, we change pt->access to be an array, and
any access in it will not include permissions ANDed from child ptes.
The test code is: https://lore.kernel.org/kvm/20210603050537.19605-1-jiangshanlai@gmail.com/
Remember to test it with TDP disabled.
The problem had existed long before the commit 41074d07c78b ("KVM: MMU:
Fix inherited permissions for emulated guest pte updates"), and it
is hard to find which is the culprit. So there is no fixes tag here.

According to the SDM 10.5.4.1:
A write of 0 to the initial-count register effectively stops the local
APIC timer, in both one-shot and periodic mode.
However, the lapic timer oneshot/periodic mode which is emulated by vmx-preemption
timer doesn't stop by writing 0 to TMICT since vmx->hv_deadline_tsc is still
programmed and the guest will receive the spurious timer interrupt later. This
patch fixes it by also cancelling the vmx-preemption timer when writing 0 to
the initial-count register.

after commit 238eca821cee
Commit 238eca821cee ("KVM: SVM: Allocate SEV command structures on local stack")
uses the local stack to allocate the structures used to communicate with the PSP,
which were earlier being kzalloced. This breaks SEV live migration for
computing the SEND_START session length and SEND_UPDATE_DATA query length as
session_len and trans_len and hdr_len fields are not zeroed respectively for
the above commands before issuing the SEV Firmware API call, hence the
firmware returns incorrect session length and update data header or trans length.
Also the SEV Firmware API returns SEV_RET_INVALID_LEN firmware error
for these length query API calls, and the return value and the
firmware error needs to be passed to the userspace as it is, so
need to remove the return check in the KVM code.

There is a time-of-check-to-time-of-use error in drm_getunique() due
to retrieving file_priv->master prior to locking the device's master
mutex.
An example can be seen in the crash report of the use-after-free error
found by Syzbot:
https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803
In the report, the master pointer was used after being freed. This is
because another process had acquired the device's master mutex in
drm_setmaster_ioctl(), then overwrote fpriv->master in
drm_new_set_master(). The old value of fpriv->master was subsequently
freed before the mutex was unlocked.
To fix this, we lock the device's master mutex before retrieving the
pointer from from fpriv->master. This patch passes the Syzbot
reproducer test.

In vc4_atomic_commit_tail() we iterate of the set of old CRTCs, and
attempt to wait on any channels which are still in use. When we iterate
over the CRTCs, we have:
* `i` - the index of the CRTC
* `channel` - the channel a CRTC is using
When we check the channel state, we consult:
old_hvs_state->fifo_state[channel].in_use
... but when we wait for the channel, we erroneously wait on:
old_hvs_state->fifo_state[i].pending_commit
... rather than:
old_hvs_state->fifo_state[channel].pending_commit
... and this bogus access has been observed to result in boot-time hangs
on some arm64 configurations, and can be detected using KASAN. FIx this
by using the correct index.
I've tested this on a Raspberry Pi 3 model B v1.2 with KASAN.

R-Car M3-W ES3.0 is marketed as R-Car M3-W+ (R8A77961), and has its own
compatible value "renesas,r8a77961".
Hence using soc_device_match() with soc_id = "r8a7796" and revision =
"ES3.*" does not actually match running on an R-Car M3-W+ SoC.
Fix this by matching with soc_id = "r8a77961" instead.

There are 2 issues on this machine, the 1st one is mic's plug/unplug
can't be detected, that is because the mic is set to manual detecting
mode, need to apply ALC255_FIXUP_XIAOMI_HEADSET_MIC to set it to auto
detecting mode. The other one is headphone's plug/unplug can't be
detected by pulseaudio, that is because the pulseaudio will use
ucm2/sof-hda-dsp on this machine, and the ucm2 only handle
'Headphone Jack', but on this machine the headphone's pincfg sets the
location to Front, then the alsa mixer name is "Front Headphone Jack"
instead of "Headphone Jack", so override the pincfg to change location
to Left.

scsi_host_dev_release() only frees dev_name when host state is
SHOST_CREATED. After host state has changed to SHOST_RUNNING,
scsi_host_dev_release() no longer cleans up.
Fix this by doing a put_device(&shost->shost_dev) in the failure path when
host state is SHOST_RUNNING. Move get_device(&shost->shost_gendev) before
device_add(&shost->shost_dev) so that scsi_host_cls_release() can do a put
on this reference.

When scsi_add_host_with_dma() returns failure, the caller will call
scsi_host_put(shost) to release everything allocated for this host
instance. Consequently we can't also free allocated stuff in
scsi_add_host_with_dma(), otherwise we will end up with a double free.
Strictly speaking, host resource allocations should have been done in
scsi_host_alloc(). However, the allocations may need information which is
not yet provided by the driver when that function is called. So leave the
allocations where they are but rely on host device's release handler to
free resources.

After device is initialized via device_initialize(), or its name is set via
dev_set_name(), the device has to be freed via put_device(). Otherwise
device name will be leaked because it is allocated dynamically in
dev_set_name().
Fix the leak by replacing kfree() with put_device(). Since
scsi_host_dev_release() properly handles IDA and kthread removal, remove
special-casing these from the error handling as well.

In commit e87b03f5830e ("afs: Prepare for use of THPs"), the return
value for afs_write_back_from_locked_page was changed from a number
of pages to a length in bytes. The loop in afs_writepages_region uses
the return value to compute the index that will be used to find dirty
pages in the next iteration, but treats it as a number of pages and
wrongly multiplies it by PAGE_SIZE. This gives a very large index value,
potentially skipping any dirty data that was not covered in the first
pass, which is limited to 256M.
This causes fsync(), and indirectly close(), to only do a partial
writeback of a large file's dirty data. The rest is eventually written
back by background threads after dirty_expire_centisecs.

kthread_stop done as part of the backend tear down. Not taking the

Commit 95722237cb2a ("ACPI: sleep: Put the FACS table after using it")
puts the FACS table during initialization.
But the hardware signature bits in the FACS table need to be accessed,
after every hibernation, to compare with the original hardware
signature.
So there is no reason to release the FACS table mapping after
initialization.
This reverts commit 95722237cb2ae4f7b73471058cdb19e8f4057c93.
An alternative solution is to use acpi_gbl_FACS variable instead, which
is mapped by the ACPICA core and never released.

On sunxi boards that use HDMI output, HDMI device probe keeps being
avoided indefinitely with these repeated messages in dmesg:
platform 1ee0000.hdmi: probe deferral - supplier 1ef0000.hdmi-phy
not ready
There's a fwnode_link being created with fw_devlink=on between hdmi
and hdmi-phy nodes, because both nodes have 'compatible' property set.
Fw_devlink code assumes that nodes that have compatible property
set will also have a device associated with them by some driver
eventually. This is not the case with the current sun8i-hdmi
driver.
This commit makes sun8i-hdmi-phy into a proper platform device
and fixes the display pipeline probe on sunxi boards that use HDMI.

In 'rt2880_pmx_group_enable' driver is printing an error and returning
-EBUSY if a pin has been already enabled. This begets anoying messages
in the caller when this happens like the following:
rt2880-pinmux pinctrl: pcie is already enabled
mt7621-pci 1e140000.pcie: Error applying setting, reverse things back
To avoid this just print the already enabled message in the pinctrl
driver and return 0 instead to not confuse the user with a real
bad problem.
