- asus-wmi: Revert retaining battery charge threshold on boot due to
userspace regression. Userspace assumed (errorneously) a
non-zero return code from sysfs read implies feature is not
supported but the correct way would be to check file
visibility instead. This results in the kernel change
breaking the functionality completely. Thus, we are taking
timeout on the kernel side to allow userspace to sort their
problem first.

Merge tag 'kvm-riscv-fixes-7.2-1' of https://github.com/kvm-riscv/linux into HEAD
KVM/riscv fixes for 7.2, take #1
- Avoid redundant page-table allocations in ioremap pcache topup
- Apply SBI FWFT LOCK flag only on successful set
- Bound SBI PMU counter mask scan to BITS_PER_LONG
- Skip TLB flush when G-stage PTE becomes valid with Svvptc
- Zicbo[m|z|p] block sizes should be always present in ONE_REG
- Inject instruction access fault on unmapped guest fetch
- Serialize virtual interrupt pending state updates using raw spinlock
- Fix Spectre-v1 in vector register access via ONE_REG
On Intel platforms with a VMX preemption timer and APICv, if a VMM
calls KVM_GET_LAPIC before KVM_GET_MSRS to save the vCPU state, it is
possible to lose a pending timer interrupt.
If the thread running these ioctls is migrated to another core after
calling KVM_GET_LAPIC but before KVM_GET_MSRS and the guest is using
their LAPIC timer in TSC-deadline mode, not only does the save LAPIC
state not carry the pending interrupt, the TSCDEADLINE MSR will be
zeroed.
After migration across CPUs, KVM_GET_MSRS calls vcpu_load, posting the
interrupt and clearing the MSR:
vcpu_load() ->
kvm_arch_vcpu_load() ->
kvm_lapic_restart_hv_timer() ->
start_hv_timer() ->
apic_timer_expired() ->
kvm_apic_inject_pending_timer_irqs()
. post interrupt into the LAPIC state
. clear IA32_TSCDEADLINE
The saved LAPIC state will be missing the pending interrupt and the saved
MSR will be zero. Oops.
Fix by only posting an interrupt when we're attempting to enter the guest
(vcpu->wants_to_run == true), not for vcpu_load from other paths.

The test asserted that the X86_FEATURE_SEV CPUID bit exactly matches
whether KVM offers KVM_X86_SEV_VM. That is not an invariant: when all
SEV ASIDs are assigned to SEV-SNP, KVM does not offer the SEV VM type
even though CPUID reports SEV, so the test aborts on an SNP-only host.
Derive SEV availability from KVM_CAP_VM_TYPES (as already done for SEV-ES
and SNP), assert only the one-way implication that a type offered by KVM
is also reported in CPUID, and TEST_REQUIRE() the SEV VM type so the test
skips cleanly when it is unavailable.

sev_smoke_test ran the plain SEV subtest unconditionally, gated only on
the X86_FEATURE_SEV CPUID bit, while gating SEV-ES and SNP on the
KVM_CAP_VM_TYPES bits. CPUID reporting SEV does not mean KVM offers the
SEV VM type: when all SEV ASIDs are assigned to SEV-SNP, KVM_X86_SEV_VM
is unavailable even though X86_FEATURE_SEV is set. On such a host the
test aborts in KVM_CREATE_VM instead of exercising the available modes.
Gate the SEV subtest on KVM_CAP_VM_TYPES like the others, so the test
runs the VM types the host actually offers.

mmu_destroy_caches() destroys pte_list_desc_cache and
mmu_page_header_cache, but leaves both pointers unchanged. The pointers
live in kvm.ko, and therefore survive when a vendor module is unloaded
while kvm.ko remains loaded.
If creation of pte_list_desc_cache fails during a subsequent vendor
module load, its assignment sets pte_list_desc_cache to NULL and the
error path calls mmu_destroy_caches(). mmu_page_header_cache still
points to the cache destroyed during the preceding vendor module
unload. Passing that stale pointer to kmem_cache_destroy() causes a
slab use-after-free.
Reproduce the issue on a v7.1.3 kernel with CONFIG_KASAN=y,
CONFIG_KASAN_GENERIC=y, CONFIG_KVM=m, and CONFIG_KVM_INTEL=m. A
one-shot test hook forces pte_list_desc_cache to NULL on the second
invocation of kvm_mmu_vendor_module_init():
1. Load kvm.ko and kvm-intel.ko, creating both caches.
2. Unload only kvm_intel, leaving kvm.ko loaded.
3. Reload kvm_intel and force initialization through the -ENOMEM path.

kvm_mmu_zap_oldest_mmu_pages() excludes a shadow page whose root_count
is non-zero from top-level reclaim, because such a page cannot be
freed. The path in mmu_page_zap_pte() that recursively zaps a parentless
nested TDP child has no such check. As a result, a shadow page can
be zapped even if the page itself can't be freed; as the comment in
kvm_mmu_zap_oldest_mmu_pages() notes, zapping it will just force vCPUs
to rebuild the page.
As in top-level reclaim, do not recursively prepare zapping of a
nested TDP child whose root_count is non-zero.

Check for a "stale" page fault, i.e. for an invalid and/or obsolete root,
after making MMU pages available for the shadow MMU. If reclaiming shadow
pages zaps an in-use root, i.e. marks it invalid, then KVM will attempt to
map memory into an invalid root. On its own, populating an invalid root is
"fine", but because child shadow pages inherit their parent's role, any
children created during the map/fetch will be created as invalid pages,
thus violating KVM's invariant that invalid pages are never on the list of
active MMU pages.
Note, the underlying flaw has existed since KVM first started tracking
invalid roots in 2008 (commit 2e53d63acb, "KVM: MMU: ignore zapped root
pagetables"), but the true badness only came along in 2020 (Linux 5.9)
with the invariant that invalid shadow pages can't be on the list of
active pages.
Note #2, inheriting role.invalid when creating child shadow pages is also
far from ideal; that flaw will be addressed separately.

free_nested() frees the shadow VMCS while vmcs01 still points to it. But
because it is asynchronous with respect to loaded_vmcs_clear(), the vCPU
might migrate before the pointer is cleared and __loaded_vmcs_clear()
may then execute VMCLEAR.
The VMCS needs to stay attached until its explicit VMCLEAR completes, but
then it can be hidden and the page safely freed.

However, if ep->event_system is longer than len (e.g. "eprobes" vs

match.

userfaultfd: prevent registration of special VMAs
tas2563_save_calibration() assigns cali_data.total_sz before it reads the
per-device calibration data from EFI, but its error paths return without
clearing it again. cali_data.cali_reg_array is left all zero, because the
function returns before the register addresses are assigned.
On the first playback tasdev_load_calibrated_data() does
if (!data || !cali_data->total_sz)
return;
which passes, since total_sz is still non-zero. It then issues five
4-byte bulk writes to p->r0_reg, p->r0_low_reg, p->invr0_reg, p->pow_reg
and p->tlimit_reg, all of which are 0. Register 0 decodes to book 0 /
page 0 / register 0x00, so the auto-incrementing block write zeroes
registers 0x00 to 0x03. Register 0x03 is PB_CFG1, which holds AMP_LEVEL,
so the amplifier gain is set to its minimum and the speaker stays silent.
This is reproducible on a Lenovo Yoga 7 14ARB7 (two TAS2563 on I2C,
ACPI INT8866) whose factory calibration was never written to UEFI, so the
EFI read fails with EFI_NOT_FOUND. The two woofers driven by the
amplifiers are silent while the tweeters driven directly by the ALC287
play. Reading the amplifier registers over i2c shows PWR_CTL = 0x00
(active) and the TDM slots correctly programmed by the RCA profile, but
PB_CFG1 = 0x00. With this change PB_CFG1 keeps its power-on default of
0x20 and both woofers play.
tas2781_save_calibration() in tas2781_hda.c already clears total_sz on
failure; do the same for the TAS2563 variant.

The OCC poll response parser walks a counted list of sensor data blocks.
It used the static backing-array capacity as the parse boundary, but a
transport response makes only data_length bytes current and valid. A
truncated response can therefore make the parser consume a block header or
block extent outside the current response.
Use data_length as the parent boundary, prove the fixed poll header and
each current block header before reading them, and prove the complete block
before advancing. Keep parsed sensor metadata local until the complete
response has passed validation, then publish it. Propagate
malformed-response errors before publishing the OCC as active.

snd_timer_close_locked() drains the closing instance's own in-flight
callback (IFLG_CALLBACK) before freeing it, but not its slaves'. When a
master instance is closed, remove_slave_links() clears each slave's
->timer; the slave's own close then reads timer == NULL and takes the
branch that skips the drain entirely (snd_timer_stop_slave() also no-ops
on a NULL timer). So a slave whose callback is still running when the
master is closed is freed underneath the live callback, leading to
use-after-free.
Drain the slaves too before remove_slave_links() severs them.
snd_timer_stop() has already taken this instance off the active list, so
no new slave callback can be queued. Take the slaves off the ack list so
a pending one can't fire either, then wait for any that is already in
flight.

The userspace-driven timer (utimer) TRIGGER ioctl calls
snd_timer_interrupt() directly with no serialization, so two threads
triggering the same utimer can run snd_timer_interrupt() on one
snd_timer concurrently.
snd_timer_process_callbacks() drops timer->lock around each instance
callback and marks the in-flight callback with the single
SNDRV_TIMER_IFLG_CALLBACK bit; snd_timer_close_locked() waits on that
bit to drain an in-flight callback before freeing the instance. The bit
cannot represent two concurrent callbacks: when a second interrupt
re-queues an instance whose callback is still running, both run at once,
the first to finish clears the bit, and the close-path drain then frees
the instance (and its callback_data) while the other callback is still
live - a use-after-free reachable by any user able to open
/dev/snd/timer, both via a user timer instance and via a sequencer queue
timer bound to the utimer.
snd_timer_interrupt() sets IFLG_CALLBACK before dropping timer->lock, so
a concurrent interrupt already observes it under the lock. Skip
re-queuing an instance (and its slaves) to the ack/sack list while its
callback is in flight; the accumulated pticks are delivered on the next
tick, so no event is lost.

folios in bio_free_folios(), and don't warn on the larger-order folio
attempts in the greedy allocation path.
- Try a slab allocation in bio_alloc_bioset() before falling back to
the mempool, restoring the previous behavior for non-sleeping
allocations from a cache-enabled bioset.
- Serialize elevator changes for the same queue using the writer lock.
- Fix a race in blk_time_get_ns() where a task preempted between
setting PF_BLOCK_TS and the cached-timestamp reload could return 0.
- blk-cgroup fix for leaks and the online flag on a radix_tree_insert()
failure in blkg_create().
- Free the copied pages when blk_rq_map_kern() fails after
blk_rq_append_bio() rejects the bio.
- Remove manually added partitions on loop device detach, fixing dead
partition devices left behind and a subsequent LOOP_CONFIGURE -EBUSY
- Bound the AIX partition lvd scan to the sector that was actually
read.

HP Pavilion x360 sets a bogus PCI SSID (103c:0000), hence the driver
picks up a wrong quirk entry, resulting in an almost silent output.
And yet, the existing quirk for x390 doesn't seem sufficing, and we
need the extra setup for the amp.
This patch adds the quirk entry for the codec SSID (103c:8486) to
initialize the amp via COEF verbs and chains to the existing quirk for
another x360 model to address the silent output.
