a315aca942 ALSA: hda: Disable power-save on KONTRON SinglePC
commit a337c355719c42a6c5b67e985ad753590ed844fb upstream.

It's been reported that the runtime PM on KONTRON SinglePC (PCI SSID
1734:1232) caused a stall of playback after a bunch of invocations.
(FWIW, this looks like an timing issue, and the stall happens rather
on the controller side.)

As a workaround, disable the default power-save on this platform.

3a60bb4510 mmc: block: Do not lose cache flush during CQE error recovery
commit 174925d340aac55296318e43fd96c0e1d196e105 upstream.

During CQE error recovery, error-free data commands get requeued if there
is any data left to transfer, but non-data commands are completed even
though they have not been processed.  Requeue them instead.

Note the only non-data command is cache flush, which would have resulted in
a cache flush being lost if it was queued at the time of CQE recovery.

77a01591cf firewire: core: fix possible memory leak in create_units()
commit 891e0eab32a57fca4d36c5162628eb0bcb1f0edf upstream.

If device_register() fails, the refcount of device is not 0, the name
allocated in dev_set_name() is leaked. To fix this by calling put_device(),
so that it will be freed in callback function kobject_cleanup().

unreferenced object 0xffff9d99035c7a90 (size 8):

fw_unit_release() will be called in the error path, move fw_device_get()

fw_unit_release().

730ac157c0 pinctrl: avoid reload of p state in list iteration
commit 4198a9b571065978632276264e01d71d68000ac5 upstream.

When in the list_for_each_entry iteration, reload of p->state->settings
with a local setting from old_state will turn the list iteration into an
infinite loop.

The typical symptom when the issue happens, will be a printk message like:

  "not freeing pin xx (xxx) as part of deactivating group xxx - it is
already used for some other setting".

This is a compiler-dependent problem, one instance occurred using Clang
version 10.0 on the arm64 architecture with linux version 4.19.

0d297dd010 USB: dwc3: qcom: fix wakeup after probe deferral
commit 41f5a0973259db9e4e3c9963d36505f80107d1a0 upstream.

The Qualcomm glue driver is overriding the interrupt trigger types
defined by firmware when requesting the wakeup interrupts during probe.

This can lead to a failure to map the DP/DM wakeup interrupts after a
probe deferral as the firmware defined trigger types do not match the
type used for the initial mapping:

	irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
	irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!

Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.

db850bcde2 bcache: prevent potential division by zero error
commit 2c7f497ac274a14330208b18f6f734000868ebf9 upstream.

In SHOW(), the variable 'n' is of type 'size_t.' While there is a
conditional check to verify that 'n' is not equal to zero before
executing the 'do_div' macro, concerns arise regarding potential
division by zero error in 64-bit environments.

The concern arises when 'n' is 64 bits in size, greater than zero, and
the lower 32 bits of it are zeros. In such cases, the conditional check
passes because 'n' is non-zero, but the 'do_div' macro casts 'n' to
'uint32_t,' effectively truncating it to its lower 32 bits.
Consequently, the 'n' value becomes zero.

To fix this potential division by zero error and ensure precise
division handling, this commit replaces the 'do_div' macro with
div64_u64(). div64_u64() is designed to work with 64-bit operands,
guaranteeing that division is performed correctly.

This change enhances the robustness of the code, ensuring that division
operations yield accurate results in all scenarios, eliminating the
possibility of division by zero, and improving compatibility across
different 64-bit environments.

In btree_gc_rewrite_node(), pointer 'n' is not checked after it returns
from btree_gc_rewrite_node(). There is potential possibility that 'n' is
a non NULL ERR_PTR(), referencing such error code is not permitted in
following code. Therefore a return value checking is necessary after 'n'

df1180184d dm-delay: fix a race between delay_presuspend and delay_bio
[ Upstream commit 6fc45b6ed921dc00dfb264dc08c7d67ee63d2656 ]

In delay_presuspend, we set the atomic variable may_delay and then stop
the timer and flush pending bios. The intention here is to prevent the
delay target from re-arming the timer again.

However, this test is racy. Suppose that one thread goes to delay_bio,
sees that dc->may_delay is one and proceeds; now, another thread executes
delay_presuspend, it sets dc->may_delay to zero, deletes the timer and
flushes pending bios. Then, the first thread continues and adds the bio to
delayed->list despite the fact that dc->may_delay is false.

Fix this bug by changing may_delay's type from atomic_t to bool and
only access it while holding the delayed_bios_lock mutex. Note that we
don't have to grab the mutex in delay_resume because there are no bios
in flight at this point.

c115564ab0 hv_netvsc: Mark VF as slave before exposing it to user-mode
commit c807d6cd089d2f4951baa838081ec5ae3e2360f8 upstream.

When a VF is being exposed form the kernel, it should be marked as "slave"
before exposing to the user-mode. The VF is not usable without netvsc
running as master. The user-mode should never see a VF without the "slave"
flag.

This commit moves the code of setting the slave flag to the time before
VF is exposed to user-mode.

commit 85520856466ed6bc3b1ccb013cddac70ceb437db upstream.

If VF NIC is registered earlier, NETDEV_REGISTER event is replayed,

Move register_netdevice_notifier() earlier, so the call back

f75617cc8d s390/dasd: protect device queue against concurrent access
commit db46cd1e0426f52999d50fa72cfa97fa39952885 upstream.

In dasd_profile_start() the amount of requests on the device queue are
counted. The access to the device queue is unprotected against
concurrent access. With a lot of parallel I/O, especially with alias
devices enabled, the device queue can change while dasd_profile_start()
is accessing the queue. In the worst case this leads to a kernel panic
due to incorrect pointer accesses.

Fix this by taking the device lock before accessing the queue and
counting the requests. Additionally the check for a valid profile data
pointer can be done earlier to avoid unnecessary locking in a hot path.

7c591abd56 KVM: arm64: limit PMU version to PMUv3 for ARMv8.1
commit c854188ea01062f5a5fd7f05658feb1863774eaa upstream.

We currently expose the PMU version of the host to the guest via
emulation of the DFR0_EL1 and AA64DFR0_EL1 debug feature registers.
However many of the features offered beyond PMUv3 for 8.1 are not
supported in KVM. Examples of this include support for the PMMIR
registers (added in PMUv3 for ARMv8.4) and 64-bit event counters
added in (PMUv3 for ARMv8.5).

Let's trap the Debug Feature Registers in order to limit
PMUVer/PerfMon in the Debug Feature Registers to PMUv3 for ARMv8.1
to avoid unexpected behaviour.

Both ID_AA64DFR0.PMUVer and ID_DFR0.PerfMon follow the "Alternative ID
scheme used for the Performance Monitors Extension version" where 0xF
means an IMPLEMENTATION DEFINED PMU is implemented, and values 0x0-0xE
are treated as with an unsigned field (with 0x0 meaning no PMU is
present). As we don't expect to expose an IMPLEMENTATION DEFINED PMU,
and our cap is below 0xF, we can treat these fields as unsigned when
applying the cap.

6881f69ad3 arm64: cpufeature: Extract capped perfmon fields
commit 8e35aa642ee4dab01b16cc4b2df59d1936f3b3c2 upstream.

When emulating ID registers there is often a need to cap the version
bits of a feature such that the guest will not use features that the
host is not aware of. For example, when KVM mediates access to the PMU
by emulating register accesses.

Let's add a helper that extracts a performance monitors ID field and
caps the version to a given value.

Fields that identify the version of the Performance Monitors Extension
do not follow the standard ID scheme, and instead follow the scheme
described in ARM DDI 0487E.a page D13-2825 "Alternative ID scheme used
for the Performance Monitors Extension version". The value 0xF means an
IMPLEMENTATION DEFINED PMU is present, and values 0x0-OxE can be treated
the same as an unsigned field with 0x0 meaning no PMU is present.

[ Upstream commit 7121205d5330c6a3cb3379348886d47c77b78d06 ]

The existing implementation uses software logic to accumulate tx
completions until the specified time (1ms) is met and then poll them.
However, there exists a tiny gap which leads to a race between
resetting and checking the tx_activate flag. Due to this the tx
completions are not reported to upper layer and tx queue timeout
kicks-in restarting the device.

To address this, introduce a tx cleanup mechanism as part of the
periodic maintenance process.

[ Upstream commit 0739af07d1d947af27c877f797cb82ceee702515 ]

Using generic ASIX Electronics Corp. AX88179 Gigabit Ethernet device,
the following test cycle has been implemented:
    - power on
    - check logs
    - shutdown
    - after detecting the system shutdown, disconnect power
    - after approximately 60 seconds of sleep, power is restored
Running some cycles, sometimes error logs like this appear:
    kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to write reg index 0x0001: -19
    kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to read reg index 0x0001: -19
    ...
These failed operation are happening during ax88179_reset execution, so
the initialization could not be correct.

In order to avoid this, we need to increase the delay after reset and
clock initial operations. By using these larger values, many cycles
have been run and no failed operations appear.

It would be better to check some status register to verify when the
operation has finished, but I do not have found any available information
(neither in the public datasheets nor in the manufacturer's driver). The
only available information for the necessary delays is the maufacturer's
driver (original values) but the proposed values are not enough for the
tested devices.

218e961e45 HID: core: store the unique system identifier in hid_device
[ Upstream commit 1e839143d674603b0bbbc4c513bca35404967dbc ]

This unique identifier is currently used only for ensuring uniqueness in
sysfs. However, this could be handful for userspace to refer to a specific
hid_device by this id.

2 use cases are in my mind: LEDs (and their naming convention), and
HID-BPF.

6523d0eda9 drm/rockchip: vop: Fix color for RGB888/BGR888 format on VOP full
[ Upstream commit bb0a05acd6121ff0e810b44fdc24dbdfaa46b642 ]

Use of DRM_FORMAT_RGB888 and DRM_FORMAT_BGR888 on e.g. RK3288, RK3328
and RK3399 result in wrong colors being displayed.

The issue can be observed using modetest:

  modetest -s <connector_id>@<crtc_id>:1920x1080-60@RG24
  modetest -s <connector_id>@<crtc_id>:1920x1080-60@BG24

Vendor 4.4 kernel apply an inverted rb swap for these formats on VOP
full framework (IP version 3.x) compared to VOP little framework (2.x).

Fix colors by applying different rb swap for VOP full framework (3.x)
and VOP little framework (2.x) similar to vendor 4.4 kernel.

c59f144e95 drm/panel: simple: Fix Innolux G101ICE-L01 timings
[ Upstream commit 3f9a91b6c00e655d27bd785dcda1742dbdc31bda ]

The Innolux G101ICE-L01 datasheet [1] page 17 table
6.1 INPUT SIGNAL TIMING SPECIFICATIONS
indicates that maximum vertical blanking time is 40 lines.
Currently the driver uses 29 lines.

Fix it, and since this panel is a DE panel, adjust the timings
to make them less hostile to controllers which cannot do 1 px
HSA/VSA, distribute the delays evenly between all three parts.

f3c2760510 RDMA/irdma: Prevent zero-length STAG registration
commit bb6d73d9add68ad270888db327514384dfa44958 upstream.

Currently irdma allows zero-length STAGs to be programmed in HW during
the kernel mode fast register flow. Zero-length MR or STAG registration
disable HW memory length checks.

Improve gaps in bounds checking in irdma by preventing zero-length STAG or
MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set.

This addresses the disclosure CVE-2023-25775.

f782929b90 net: sched: fix race condition in qdisc_graft()
commit ebda44da44f6f309d302522b049f43d6f829f7aa upstream.

We had one syzbot report [1] in syzbot queue for a while.
I was waiting for more occurrences and/or a repro but
Dmitry Vyukov spotted the issue right away.

<quoting Dmitry>
qdisc_graft() drops reference to qdisc in notify_and_destroy
while it's still assigned to dev->qdisc
</quoting>

Indeed, RCU rules are clear when replacing a data structure.
The visible pointer (dev->qdisc in this case) must be updated
to the new object _before_ RCU grace period is started
(qdisc_put(old) in this case).

0cf5544469 iomap: Set all uptodate bits for an Uptodate page
commit 4595a298d5563cf76c1d852970f162051fd1a7a6 upstream.

For filesystems with block size < page size, we need to set all the
per-block uptodate bits if the page was already uptodate at the time
we create the per-block metadata.  This can happen if the page is
invalidated (eg by a write to drop_caches) but ultimately not removed
from the page cache.

This is a data corruption issue as page writeback skips blocks which
are marked !uptodate.

7907729cc5 scsi: virtio_scsi: limit number of hw queues by nr_cpu_ids
commit 1978f30a87732d4d9072a20abeded9fe17884f1b upstream.

When tag_set->nr_maps is 1, the block layer limits the number of hw queues
by nr_cpu_ids. No matter how many hw queues are used by virtio-scsi, as it
has (tag_set->nr_maps == 1), it can use at most nr_cpu_ids hw queues.

In addition, specifically for pci scenario, when the 'num_queues' specified
by qemu is more than maxcpus, virtio-scsi would not be able to allocate
more than maxcpus vectors in order to have a vector for each queue. As a
result, it falls back into MSI-X with one vector for config and one shared
for queues.

Considering above reasons, this patch limits the number of hw queues used
by virtio-scsi by nr_cpu_ids.

e9cafc688b ext4: remove gdb backup copy for meta bg in setup_new_flex_group_blocks
commit 40dd7953f4d606c280074f10d23046b6812708ce upstream.

Wrong check of gdb backup in meta bg as following:
first_group is the first group of meta_bg which contains target group, so
target group is always >= first_group. We check if target group has gdb
backup by comparing first_group with [group + 1] and [group +
EXT4_DESC_PER_BLOCK(sb) - 1]. As group >= first_group, then [group + N] is
> first_group. So no copy of gdb backup in meta bg is done in
setup_new_flex_group_blocks.

No need to do gdb backup copy in meta bg from setup_new_flex_group_blocks
as we always copy updated gdb block to backups at end of
ext4_flex_group_add as following:

ext4_flex_group_add
  /* no gdb backup copy for meta bg any more */
  setup_new_flex_group_blocks

  /* update current group number */
  ext4_update_super
    sbi->s_groups_count += flex_gd->count;

  /*
   * if group in meta bg contains backup is added, the primary gdb block
   * of the meta bg will be copy to backup in new added group here.
   */
  for (; gdb_num <= gdb_num_end; gdb_num++)
    update_backups(...)

In summary, we can remove wrong gdb backup copy code in
setup_new_flex_group_blocks.

8fceeaed22 ext4: correct offset of gdb backup in non meta_bg group to update_backups
commit 31f13421c004a420c0e9d288859c9ea9259ea0cc upstream.

Commit 0aeaa2559d6d5 ("ext4: fix corruption when online resizing a 1K
bigalloc fs") found that primary superblock's offset in its group is
not equal to offset of backup superblock in its group when block size
is 1K and bigalloc is enabled. As group descriptor blocks are right
after superblock, we can't pass block number of gdb to update_backups
for the same reason.

The root casue of the issue above is that leading 1K padding block is
count as data block offset for primary block while backup block has no
padding block offset in its group.

Remove padding data block count to fix the issue for gdb backups.

For meta_bg case, update_backups treat blk_off as block number, do no
conversion in this case.

80c85deccd ext4: apply umask if ACL support is disabled
commit 484fd6c1de13b336806a967908a927cc0356e312 upstream.

The function ext4_init_acl() calls posix_acl_create() which is
responsible for applying the umask.  But without
CONFIG_EXT4_FS_POSIX_ACL, ext4_init_acl() is an empty inline function,
and nobody applies the umask.

This fixes a bug which causes the umask to be ignored with O_TMPFILE
on ext4:

commit 6a26310273c323380da21eb23fcfd50e31140913 upstream.

This reverts commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df.

I couldn't reproduce the reported issue. What I did, based on a pcap
packet log provided by the reporter:
- Used same chip version (RTL8168h)
- Set MAC address to the one used on the reporters system
- Replayed the EAPOL unicast packet that, according to the reporter,
  was filtered out by the mc filter.
The packet was properly received.

Therefore the root cause of the reported issue seems to be somewhere
else. Disabling mc filtering completely for the most common chip
version is a quite big hammer. Therefore revert the change and wait
for further analysis results from the reporter.
