f7b32e7850 io_uring: fix mutex_unlock with unreferenced ctx
Callers of mutex_unlock() have to make sure that the mutex stays alive
for the whole duration of the function call. For io_uring that means
that the following pattern is not valid unless we ensure that the
context outlives the mutex_unlock() call.

mutex_lock(&ctx->uring_lock);
req_put(req); // typically via io_req_task_submit()
mutex_unlock(&ctx->uring_lock);

Most contexts are fine: io-wq pins requests, syscalls hold the file,
task works are taking ctx references and so on. However, the task work
fallback path doesn't follow the rule.

4b0768b655 r8169: fix rtl8125b PAUSE frames blasting when suspended
When FIFO reaches near full state, device will issue pause frame.
If pause slot is enabled(set to 1), in this time, device will issue
pause frame only once. But if pause slot is disabled(set to 0), device
will keep sending pause frames until FIFO reaches near empty state.

When pause slot is disabled, if there is no one to handle receive
packets, device FIFO will reach near full state and keep sending
pause frames. That will impact entire local area network.

This issue can be reproduced in Chromebox (not Chromebook) in
developer mode running a test image (and v5.10 kernel):
1) ping -f $CHROMEBOX (from workstation on same local network)
2) run "powerd_dbus_suspend" from command line on the $CHROMEBOX
3) ping $ROUTER (wait until ping fails from workstation)

Takes about ~20-30 seconds after step 2 for the local network to
stop working.

Fix this issue by enabling pause slot to only send pause frame once
when FIFO reaches near full state.

9f6acd2b4d arm64: dts: rockchip: Fix Turing RK1 interrupt pinctrls
The pinctrls for the hym8563 interrupt line and fan-tach input
were both mistakenly defined as `pcfg_pull_none`. As these are
active-low signals (level-triggered, in the hym8563 case) which
may not be driven at times, these should really be pull-up. The
lack of any bias results in spurious interrupts.

Fix this by modifying the `rockchip,pins` properties as necessary
to enable the pull-up resistors.

9b8493dc43 x86/CPU/AMD: Check vendor in the AMD microcode callback
Commit in Fixes added an AMD-specific microcode callback. However, it
didn't check the CPU vendor the kernel runs on explicitly.

The only reason the Zenbleed check in it didn't run on other x86 vendors
hardware was pure coincidental luck:

  if (!cpu_has_amd_erratum(c, amd_zenbleed))
	  return;

gives true on other vendors because they don't have those families and
models.

However, with the removal of the cpu_has_amd_erratum() in

  05f5f73936 ("x86/CPU/AMD: Drop now unused CPU erratum checking function")

that coincidental condition is gone, leading to the zenbleed check
getting executed on other vendors too.

Add the explicit vendor check for the whole callback as it should've
been done in the first place.

16b55b1f22 net/tg3: fix race condition in tg3_reset_task()
When an EEH error is encountered by a PCI adapter, the EEH driver
modifies the PCI channel's state as shown below:

   enum {
      /* I/O channel is in normal state */
      pci_channel_io_normal = (__force pci_channel_state_t) 1,

      /* I/O to channel is blocked */
      pci_channel_io_frozen = (__force pci_channel_state_t) 2,

      /* PCI card is dead */
      pci_channel_io_perm_failure = (__force pci_channel_state_t) 3,
   };

If the same EEH error then causes the tg3 driver's transmit timeout
logic to execute, the tg3_tx_timeout() function schedules a reset
task via tg3_reset_task_schedule(), which may cause a race condition
between the tg3 and EEH driver as both attempt to recover the HW via
a reset action.

EEH driver gets error event
--> eeh_set_channel_state()
    and set device to one of
    error state above           scheduler: tg3_reset_task() get
                                returned error from tg3_init_hw()
                             --> dev_close() shuts down the interface
tg3_io_slot_reset() and
tg3_io_resume() fail to
reset/resume the device

To resolve this issue, we avoid the race condition by checking the PCI
channel state in the tg3_reset_task() function and skip the tg3 driver
initiated reset when the PCI channel is not in the normal state.  (The
driver has no access to tg3 device registers at this point and cannot
even complete the reset task successfully without external assistance.)
We'll leave the reset procedure to be managed by the EEH driver which
calls the tg3_io_error_detected(), tg3_io_slot_reset() and
tg3_io_resume() functions as appropriate.

Adding the same checking in tg3_dump_state() to avoid dumping all
device registers when the PCI channel is not in the normal state.

815fb87b75 Power management fixes for 6.7-rc4
- Fix the AMD P-state driver's EPP sysfs interface in the cases when the
    performance governor is in use (Ayush Jain).
 
  - Make the ->fast_switch() callback in the AMD P-state driver return the
    target frequency as expected (Gautham R. Shenoy).
 
  - Allow user space to control the range of frequencies to use via
    scaling_min_freq and scaling_max_freq when AMD P-state driver is in
    use (Wyes Karny).
 
  - Prevent power domains needed for wakeup signaling from being turned
    off during system suspend on Qualcomm systems and prevent performance
    states votes from runtime-suspended devices from being lost across
    a system suspend-resume cycle in qcom-cpufreq-nvmem (Stephan Gerhold).
 
  - Fix disabling the 792 Mhz OPP in the imx6q cpufreq driver for the
    i.MX6ULL types that can run at that frequency (Christoph Niedermaier).
 
  - Eliminate unnecessary and harmful conversions to uW from the DTPM
    (dynamic thermal and power management) framework (Lukasz Luba).

dfce9cb314 bpf: Fix a verifier bug due to incorrect branch offset comparison with cpu=v4
Bpf cpu=v4 support is introduced in [1] and Commit 4cd58e9af8
("bpf: Support new 32bit offset jmp instruction") added support for new
32bit offset jmp instruction. Unfortunately, in function
bpf_adj_delta_to_off(), for new branch insn with 32bit offset, the offset
(plus/minor a small delta) compares to 16-bit offset bound
[S16_MIN, S16_MAX], which caused the following verification failure:
  $ ./test_progs-cpuv4 -t verif_scale_pyperf180
  ...
  insn 10 cannot be patched due to 16-bit range
  ...
  libbpf: failed to load object 'pyperf180.bpf.o'
  scale_test:FAIL:expect_success unexpected error: -12 (errno 12)
  #405     verif_scale_pyperf180:FAIL

Note that due to recent llvm18 development, the patch [2] (already applied
in bpf-next) needs to be applied to bpf tree for testing purpose.

The fix is rather simple. For 32bit offset branch insn, the adjusted
offset compares to [S32_MIN, S32_MAX] and then verification succeeded.

c467e97f07 md/raid6: use valid sector values to determine if an I/O should wait on the reshape
During a reshape or a RAID6 array such as expanding by adding an additional
disk, I/Os to the region of the array which have not yet been reshaped can
stall indefinitely. This is from errors in the stripe_ahead_of_reshape
function causing md to think the I/O is to a region in the actively
undergoing the reshape.

stripe_ahead_of_reshape fails to account for the q disk having a sector
value of 0. By not excluding the q disk from the for loop, raid6 will always
generate a min_sector value of 0, causing a return value which stalls.

The function's max_sector calculation also uses min() when it should use
max(), causing the max_sector value to always be 0. During a backwards
rebuild this can cause the opposite problem where it allows I/O to advance
when it should wait.

Fixing these errors will allow safe I/O to advance in a timely manner and
delay only I/O which is unsafe due to stripes in the middle of undergoing
the reshape.

ea61294bef Revert "KVM: Prevent module exit until all VMs are freed"
Revert KVM's misguided attempt to "fix" a use-after-module-unload bug that
was actually due to failure to flush a workqueue, not a lack of module
refcounting.  Pinning the KVM module until kvm_vm_destroy() doesn't
prevent use-after-free due to the module being unloaded, as userspace can
invoke delete_module() the instant the last reference to KVM is put, i.e.
can cause all KVM code to be unmapped while KVM is actively executing said
code.

Generally speaking, the many instances of module_put(THIS_MODULE)
notwithstanding, outside of a few special paths, a module can never safely
put the last reference to itself without creating deadlock, i.e. something
external to the module *must* put the last reference.  In other words,
having VMs grab a reference to the KVM module is futile, pointless, and as
evidenced by the now-reverted commit 70375c2d8f ("Revert "KVM: set owner
of cpu and vm file operations""), actively dangerous.

This reverts commit 405294f29f and commit
5f6de5cbeb.

087e15206d KVM: Set file_operations.owner appropriately for all such structures
Set .owner for all KVM-owned filed types so that the KVM module is pinned
until any files with callbacks back into KVM are completely freed.  Using
"struct kvm" as a proxy for the module, i.e. keeping KVM-the-module alive
while there are active VMs, doesn't provide full protection.

Userspace can invoke delete_module() the instant the last reference to KVM
is put.  If KVM itself puts the last reference, e.g. via kvm_destroy_vm(),
then it's possible for KVM to be preempted and deleted/unloaded before KVM
fully exits, e.g. when the task running kvm_destroy_vm() is scheduled back
in, it will jump to a code page that is no longer mapped.

Note, file types that can call into sub-module code, e.g. kvm-intel.ko or
kvm-amd.ko on x86, must use the module pointer passed to kvm_init(), not
THIS_MODULE (which points at kvm.ko).  KVM assumes that if /dev/kvm is
reachable, e.g. VMs are active, then the vendor module is loaded.

To reduce the probability of forgetting to set .owner entirely, use
THIS_MODULE for stats files where KVM does not call back into vendor code.

This reverts commit 70375c2d8f, and fixes
several other file types that have been buggy since their introduction.

Fixes: 70375c2d8f ("Revert "KVM: set owner of cpu and vm file operations"")
Fixes: 3bcd0662d6 ("KVM: X86: Introduce mmu_rmaps_stat per-vm debugfs file")

74fbc88e16 nvme-core: check for too small lba shift
The block layer doesn't support logical block sizes smaller than 512
bytes. The nvme spec doesn't support that small either, but the driver
isn't checking to make sure the device responded with usable data.
Failing to catch this will result in a kernel bug, either from a
division by zero when stacking, or a zero length bio.

0e4237ae8d blk-mq: don't count completed flush data request as inflight in case of quiesce
Request queue quiesce may interrupt flush sequence, and the original request
may have been marked as COMPLETE, but can't get finished because of
queue quiesce.

This way is fine from driver viewpoint, because flush sequence is block
layer concept, and it isn't related with driver.

However, driver(such as dm-rq) can call blk_mq_queue_inflight() to count &
drain inflight requests, then the wait & drain never gets done because
the completed & not-finished flush request is counted as inflight.

Fix this issue by not counting completed flush data request as inflight in
case of quiesce.

To avoid such issue, split the dai array into HDMI and non HDMI array and
register them conditionally:
for HDMI hdev only register the dais needed for HDMI
for non HDMI hdev do not  register the HDMI dais.
