Konrad Dybcio ea4eceef16 dt-bindings: clock: qcom,gcc-sc8280xp: Add missing GDSCs
[ Upstream commit 9eba4db02a ]

There are 10 more GDSCs that we've not been caring about, and by extension
(and perhaps even more importantly), not putting to sleep. Add them.

[ Upstream commit b8d72e32e1 ]

The adapter scan ssif_info_find() sets info->adapter_name if the adapter
info came from SMBIOS, as it's not set in that case.  However, this
function can be called more than once, and it will leak the adapter name
if it had already been set.  So check for NULL before setting it.

an error. When error happens, make sure *rac97 is NULL is safer.

For examble, in snd_vortex_mixer():
	err = snd_ac97_mixer(pbus, &ac97, &vortex->codec);
	vortex->isquad = ((vortex->codec == NULL) ?
		0 : (vortex->codec->ext_id&0x80));
If error happened but vortex->codec isn't NULL, this may cause some
problems.

Move the judgement order to be clearer and better.

The removal check in of_unittest_apply_revert_overlay_check()
always uses the platform device overlay type, while it should use the
actual overlay type, as passed as a parameter to the function.

This has no impact on any current test, as all tests calling
of_unittest_apply_revert_overlay_check() use the platform device overlay
type.

Geert Uytterhoeven be86241bf5 of: overlay: Call of_changeset_init() early
[ Upstream commit a9515ff4fb ]

When of_overlay_fdt_apply() fails, the changeset may be partially
applied, and the caller is still expected to call of_overlay_remove() to
clean up this partial state.

However, of_overlay_apply() calls of_resolve_phandles() before
init_overlay_changeset().  Hence if the overlay fails to apply due to an
unresolved symbol, the overlay_changeset.cset.entries list is still
uninitialized, and cleanup will crash with a NULL-pointer dereference in
overlay_removal_is_ok().

Fix this by moving the call to of_changeset_init() from
init_overlay_changeset() to of_overlay_fdt_apply(), where all other
early initialization is done.

David Jeffery 293c2dd9ed md: raid0: account for split bio in iostat accounting
[ Upstream commit cc22b5407e ]

When a bio is split by md raid0, the newly created bio will not be tracked
by md for I/O accounting. Only the portion of I/O still assigned to the
original bio which was reduced by the split will be accounted for. This
results in md iostat data sometimes showing I/O values far below the actual
amount of data being sent through md.

md_account_bio() needs to be called for all bio generated by the bio split.

A simple example of the issue was generated using a raid0 device on partitions
to the same device. Since all raid0 I/O then goes to one device, it makes it
easy to see a gap between the md device and its sd storage. Reading an lvm
device on top of the md device, the iostat output (some 0 columns and extra
devices removed to make the data more compact) was:

Device             tps    kB_read/s    kB_wrtn/s    kB_dscd/s    kB_read

I/O was generated doing large direct I/O reads (12M) with dd to a linear
lvm volume on top of the 4 leg raid0 device.

The md2 reads were showing as roughly 2/3 of the reads to the sde device
containing all of md2's raid partitions. The sum of reads to sde was
1826816 kB, which was the expected amount as it was the amount read by
dd. With the patch, the total reads from md will match the reads from
sde and be consistent with the amount of I/O generated.

Jan Kara f34142ab4e md/raid0: Fix performance regression for large sequential writes
[ Upstream commit 319ff40a54 ]

Commit f00d7c85be ("md/raid0: fix up bio splitting.") among other
things changed how bio that needs to be split is submitted. Before this
commit, we have split the bio, mapped and submitted each part. After
this commit, we map only the first part of the split bio and submit the
second part unmapped. Due to bio sorting in __submit_bio_noacct() this
results in the following request ordering:

  9,0   18     1181     0.525037895 15995  Q  WS 1479315464 + 63392

  Split off chunk-sized (1024 sectors) request:

  9,0   18     1182     0.629019647 15995  X  WS 1479315464 / 1479316488

  Request is unaligned to the chunk so it's split in
  raid0_make_request().  This is the first part mapped and punted to
  bio_list:

  8,0   18     7053     0.629020455 15995  A  WS 739921928 + 1016 <- (9,0) 1479315464

  Now raid0_make_request() returns, second part is postponed on
  bio_list. __submit_bio_noacct() resorts the bio_list, mapped request
  is submitted to the underlying device:

  8,0   18     7054     0.629022782 15995  G  WS 739921928 + 1016

  Now we take another request from the bio_list which is the remainder
  of the original huge request. Split off another chunk-sized bit from
  it and the situation repeats:

  9,0   18     1183     0.629024499 15995  X  WS 1479316488 / 1479317512
  8,16  18     6998     0.629025110 15995  A  WS 739921928 + 1016 <- (9,0) 1479316488
  8,16  18     6999     0.629026728 15995  G  WS 739921928 + 1016
  ...
  9,0   18     1184     0.629032940 15995  X  WS 1479317512 / 1479318536 [libnetacq-write]
  8,0   18     7059     0.629033294 15995  A  WS 739922952 + 1016 <- (9,0) 1479317512
  8,0   18     7060     0.629033902 15995  G  WS 739922952 + 1016
  ...

  This repeats until we consume the whole original huge request. Now we
  finally get to processing the second parts of the split off requests
  (in reverse order):

  8,16  18     7181     0.629161384 15995  A  WS 739952640 + 8 <- (9,0) 1479377920
  8,0   18     7239     0.629162140 15995  A  WS 739952640 + 8 <- (9,0) 1479376896
  8,16  18     7186     0.629163881 15995  A  WS 739951616 + 8 <- (9,0) 1479375872
  8,0   18     7242     0.629164421 15995  A  WS 739951616 + 8 <- (9,0) 1479374848
  ...

I guess it is obvious that this IO pattern is extremely inefficient way
to perform sequential IO. It also makes bio_list to grow to rather long
lengths.

Change raid0_make_request() to map both parts of the split bio. Since we
know we are provided with at most chunk-sized bios, we will always need
to split the incoming bio at most once.

This happens because iocg->ioc is NULL. The field is initialized by
ioc_pd_init() and never cleared. The NULL deref is caused by
blkcg_activate_policy() installing blkg_policy_data before initializing it.

blkcg_activate_policy() was doing the following:

1. Allocate pd's for all existing blkg's and install them in blkg->pd[].
2. Initialize all pd's.
3. Online all pd's.

blkcg_activate_policy() only grabs the queue_lock and may release and
re-acquire the lock as allocation may need to sleep. ioc_weight_write()
grabs blkcg->lock and iterates all its blkg's. The two can race and if
ioc_weight_write() runs during #1 or between #1 and #2, it can encounter a
pd which is not initialized yet, leading to crash.

The crash can be reproduced with the following script:

  #!/bin/bash

  echo +io > /sys/fs/cgroup/cgroup.subtree_control
  systemd-run --unit touch-sda --scope dd if=/dev/sda of=/dev/null bs=1M count=1 iflag=direct

I don't see a reason why all pd's should be allocated, initialized and
onlined together. The only ordering requirement is that parent blkgs to be
initialized and onlined before children, which is guaranteed from the
walking order. Let's fix the bug by allocating, initializing and onlining pd
for each blkg and holding blkcg->lock over initialization and onlining. This
ensures that an installed blkg is always fully initialized and onlined
removing the the race window.

Vlad Karpovich dc98c6c086 firmware: cs_dsp: Fix new control name check
[ Upstream commit 7ac1102b22 ]

Before adding a new FW control, its name is checked against
existing controls list. But the string length in strncmp used
to compare controls names is taken from the list, so if beginnings
of the controls are matching,  then the new control is not created.
For example, if CAL_R control already exists, CAL_R_SELECTED
is not created.
The fix is to compare string lengths as well.

Yu Kuai 7a8b6d9399 md/raid5-cache: fix null-ptr-deref for r5l_flush_stripe_to_raid()
[ Upstream commit 0d0bd28c50 ]

r5l_flush_stripe_to_raid() will check if the list 'flushing_ios' is
empty, and then submit 'flush_bio', however, r5l_log_flush_endio()
is clearing the list first and then clear the bio, which will cause
null-ptr-deref:

T1: submit flush io
raid5d
 handle_active_stripes
  r5l_flush_stripe_to_raid
   // list is empty
   // add 'io_end_ios' to the list
   bio_init
   submit_bio
   // io1

T2: io1 is done
r5l_log_flush_endio
 list_splice_tail_init
 // clear the list
			T3: submit new flush io
			...
			r5l_flush_stripe_to_raid
			 // list is empty
			 // add 'io_end_ios' to the list
			 bio_init
 bio_uninit
 // clear bio->bi_blkg
			 submit_bio
			 // null-ptr-deref

Fix this problem by clearing bio before clearing the list in
r5l_log_flush_endio().

Yu Kuai 71cf23271f md/raid5-cache: fix a deadlock in r5l_exit_log()
[ Upstream commit a705b11b35 ]

Commit b13015af94 ("md/raid5-cache: Clear conf->log after finishing

// caller hold reconfig_mutex
r5l_exit_log
 flush_work(&log->disable_writeback_work)
			r5c_disable_writeback_async
			 wait_event
			  /*
			   * conf->log is not NULL, and mddev_trylock()
			   * will fail, wait_event() can never pass.
			   */
 conf->log = NULL

Fix this problem by setting 'config->log' to NULL before wake_up() as it
used to be, so that wait_event() from r5c_disable_writeback_async() can
exist. In the meantime, move forward md_unregister_thread() so that
null-ptr-deref this commit fixed can still be fixed.

Stephan Gerhold da20170162 arm64: dts: qcom: msm8916: Define regulator constraints next to usage
[ Upstream commit b0a8f16ae4 ]

Right now each MSM8916 device has a huge block of regulator constraints
with allowed voltages for each regulator. For lack of better
documentation these voltages are often copied as-is from the vendor
device tree, without much extra thought.

Unfortunately, the voltages in the vendor device trees are often
misleading or even wrong, e.g. because:

 - There is a large voltage range allowed and the actual voltage is
   only set somewhere hidden in some messy vendor driver. This is often
   the case for pm8916_{l14,l15,l16} because they have a broad range of
   1.8-3.3V by default.

 - The voltage is actually wrong but thanks to the voltage constraints
   in the RPM firmware it still ends up applying the correct voltage.

To have proper regulator constraints it is important to review them in
context of the usage. The current setup in the MSM8916 device trees
makes this quite hard because each device duplicates the standard
voltages for components of the SoC and mixes those with minor
device-specific additions and dummy voltages for completely unused
regulators.

The actual usage of the regulators for the SoC components is in
msm8916-pm8916.dtsi, so it can and should also define the related
voltage constraints. These are not board-specific but defined in the
APQ8016E/PM8916 Device Specification. The board DT can then focus on
describing the actual board-specific regulators, which makes it much
easier to review and spot potential mistakes there.

Note that this commit does not make any functional change. All used
regulators still have the same regulator constraints as before. Unused
regulators do not have regulator constraints anymore because most of
these were too broad or even entirely wrong. They should be added back
with proper voltage constraints when there is an actual usage.

Stephan Gerhold 8d62b20ab7 arm64: dts: qcom: msm8916: Fix regulator constraints
[ Upstream commit 355750828c ]

The regulator constraints for most MSM8916 devices (except DB410c) were
originally taken from Qualcomm's msm-3.10 vendor device tree (for lack
of better documentation). Unfortunately it turns out that Qualcomm's
voltages are slightly off as well and do not match the voltage
constraints applied by the RPM firmware.

This means that we sometimes request a specific voltage but the RPM
firmware actually applies a much lower or higher voltage. This is
particularly critical for pm8916_l11 which is used as SD card VMMC
regulator: The SD card can choose a voltage from the current range of
1.8 - 2.95V. If it chooses to run at 1.8V we pretend that this is fine
but the RPM firmware will still silently end up configuring 2.95V.
This can be easily reproduced with a multimeter or by checking the
SPMI hardware registers of the regulator.

Fix this by making the voltages match the actual "specified range" in
the PM8916 Device Specification which is enforced by the RPM firmware.

The ov5640 has depended on these names since the driver was committed

regulator names since its own initial commit in 2020.

Perhaps the regulators were left on in previous 410c bootloaders. In any

The Display Data Channel (DDC) transactions between an HDMI transmitter

While the SIL9022A can transact with the core at 400KHz, it needs to
drop the frequency to 100KHz when communicating with the monitor,
otherwise, the i2c controller times out and shows warning like this.

[  985.773431] omap_i2c 20010000.i2c: controller timed out

That feature, however, has not been enabled in the SIL9022 driver.

Since, dropping the frequency doesn't affect any other devices on the

Pavel Begunkov ec2273b61a io_uring: fix drain stalls by invalid SQE
[ Upstream commit cfdbaa3a29 ]

cq_extra is protected by ->completion_lock, which io_get_sqe() misses.
The bug is harmless as it doesn't happen in real life, requires invalid
SQ index array and racing with submission, and only messes up the
userspace, i.e. stall requests execution but will be cleaned up on
ring destruction.

Zhiguo Niu 39215fc86d block/mq-deadline: use correct way to throttling write requests
[ Upstream commit d47f9717e5 ]

The original formula was inaccurate:
dd->async_depth = max(1UL, 3 * q->nr_requests / 4);

For write requests, when we assign a tags from sched_tags,
data->shallow_depth will be passed to sbitmap_find_bit,
see the following code:

nr = sbitmap_find_bit_in_word(&sb->map[index],
			min_t (unsigned int,
			__map_depth(sb, index),
			depth),
			alloc_hint, wrap);

The smaller of data->shallow_depth and __map_depth(sb, index)
will be used as the maximum range when allocating bits.

For a mmc device (one hw queue, deadline I/O scheduler):
q->nr_requests = sched_tags = 128, so according to the previous
calculation method, dd->async_depth = data->shallow_depth = 96,
and the platform is 64bits with 8 cpus, sched_tags.bitmap_tags.sb.shift=5,
sb.maps[]=32/32/32/32, 32 is smaller than 96, whether it is a read or
a write I/O, tags can be allocated to the maximum range each time,
which has not throttling effect.

In addition, refer to the methods of bfg/kyber I/O scheduler,
limit ratiois are calculated base on sched_tags.bitmap_tags.sb.shift.

This patch can throttle write requests really.

Gaosheng Cui 8a40b49137 audit: fix possible soft lockup in __audit_inode_child()
[ Upstream commit b59bc6e372 ]

Tracefs or debugfs maybe cause hundreds to thousands of PATH records,
too many PATH records maybe cause soft lockup.

For example:
  1. CONFIG_KASAN=y && CONFIG_PREEMPTION=n
  2. auditctl -a exit,always -S open -k key
  3. sysctl -w kernel.watchdog_thresh=5
  4. mkdir /sys/kernel/debug/tracing/instances/test

There may be a soft lockup as follows:

Fabio Estevam f0f805279d drm/msm/a2xx: Call adreno_gpu_init() earlier
[ Upstream commit db07ce5da8 ]

The adreno_is_a20x() and adreno_is_a225() functions rely on the
GPU revision, but such information is retrieved inside adreno_gpu_init(),
which is called afterwards.

Fix this problem by caling adreno_gpu_init() earlier, so that
the GPU information revision is available when adreno_is_a20x()
and adreno_is_a225() run.

Tested on a imx53-qsb board.

Dan Carpenter c325854ad8 smackfs: Prevent underflow in smk_set_cipso()
[ Upstream commit 3ad49d37cf ]

There is a upper bound to "catlen" but no lower bound to prevent
negatives.  I don't see that this necessarily causes a problem but we
may as well be safe.
