[PATCH AUTOSEL 6.1 01/47] phy: qcom-snps-femto-v2: keep cfg_ahb_clk enabled during runtime suspend

[Sasha Levin]

From: Adrien Thierry <athierry@redhat.com>

[ Upstream commit 45d89a344eb46db9dce851c28e14f5e3c635c251 ]

In the dwc3 core, both system and runtime suspend end up calling
dwc3_suspend_common(). From there, what happens for the PHYs depends on
the USB mode and whether the controller is entering system or runtime
suspend.

HOST mode:
  (1) system suspend on a non-wakeup-capable controller

  The [1] if branch is taken. dwc3_core_exit() is called, which ends up
  calling phy_power_off() and phy_exit(). Those two functions decrease the
  PM runtime count at some point, so they will trigger the PHY runtime
  sleep (assuming the count is right).

  (2) runtime suspend / system suspend on a wakeup-capable controller

  The [1] branch is not taken. dwc3_suspend_common() calls
  phy_pm_runtime_put_sync(). Assuming the ref count is right, the PHY
  runtime suspend op is called.

DEVICE mode:
  dwc3_core_exit() is called on both runtime and system sleep
  unless the controller is already runtime suspended.

OTG mode:
  (1) system suspend : dwc3_core_exit() is called

  (2) runtime suspend : do nothing

In host mode, the code seems to make a distinction between 1) runtime
sleep / system sleep for wakeup-capable controller, and 2) system sleep
for non-wakeup-capable controller, where phy_power_off() and phy_exit()
are only called for the latter. This suggests the PHY is not supposed to
be in a fully powered-off state for runtime sleep and system sleep for
wakeup-capable controller.

Moreover, downstream, cfg_ahb_clk only gets disabled for system suspend.
The clocks are disabled by phy->set_suspend() [2] which is only called
in the system sleep path through dwc3_core_exit() [3].

With that in mind, don't disable the clocks during the femto PHY runtime
suspend callback. The clocks will only be disabled during system suspend
for non-wakeup-capable controllers, through dwc3_core_exit().

[PATCH AUTOSEL 6.1 06/47] platform/x86: serial-multi-instantiate: Auto detect IRQ resource for CSC3551

[Sasha Levin]

From: David Xu <xuwd1@hotmail.com>

[ Upstream commit 676b7c5ecab36274442887ceadd6dee8248a244f ]

The current code assumes that the CSC3551(multiple cs35l41) always have
its interrupt pin connected to GPIO thus the IRQ can be acquired with
acpi_dev_gpio_irq_get. However on some newer laptop models this is no
longer the case as they have the CSC3551's interrupt pin connected to
APIC. This causes smi_i2c_probe to fail on these machines.

To support these machines, a new macro IRQ_RESOURCE_AUTO was introduced
for cs35l41 smi_node, and smi_get_irq function was modified so it tries
to get GPIO irq resource first and if failed, tries to get
APIC irq resource for cs35l41.

This patch affects only the cs35l41's probing and brings no negative
influence on machines that indeed have the cs35l41's interrupt pin
connected to GPIO.

[PATCH AUTOSEL 6.1 07/47] 9p: virtio: fix unlikely null pointer deref in handle_rerror

[Sasha Levin]

From: Dominique Martinet <asmadeus@codewreck.org>

[ Upstream commit 13ade4ac5c28e8a014fa85278f5a4270b215f906 ]

handle_rerror can dereference the pages pointer, but it is not
necessarily set for small payloads.
In practice these should be filtered out by the size check, but
might as well double-check explicitly.

[PATCH AUTOSEL 6.1 08/47] 9p: virtio: make sure 'offs' is initialized in zc_request

[Sasha Levin]

From: Dominique Martinet <asmadeus@codewreck.org>

[ Upstream commit 4a73edab69d3a6623f03817fe950a2d9585f80e4 ]

Similarly to the previous patch: offs can be used in handle_rerrors
without initializing on small payloads; in this case handle_rerrors will
not use it because of the size check, but it doesn't hurt to make sure
it is zero to please scan-build.

This fixes the following warning:

[PATCH AUTOSEL 6.1 10/47] ksmbd: validate session id and tree id in compound request

[Sasha Levin]

From: Namjae Jeon <linkinjeon@kernel.org>

[ Upstream commit 3df0411e132ee74a87aa13142dfd2b190275332e ]

`smb2_get_msg()` in smb2_get_ksmbd_tcon() and smb2_check_user_session()
will always return the first request smb2 header in a compound request.
if `SMB2_TREE_CONNECT_HE` is the first command in compound request, will
return 0, i.e. The tree id check is skipped.
This patch use ksmbd_req_buf_next() to get current command in compound.

[PATCH AUTOSEL 6.1 13/47] ASoC: da7219: Flush pending AAD IRQ when suspending

[Sasha Levin]

From: Dmytro Maluka <dmy@semihalf.com>

[ Upstream commit 91e292917dad64ab8d1d5ca2ab3069ad9dac6f72 ]

da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.

This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

[  355.876211] i2c_designware i2c_designware.3: Transfer while suspended
[  355.876245] WARNING: CPU: 2 PID: 3576 at drivers/i2c/busses/i2c-designware-master.c:570 i2c_dw_xfer+0x411/0x440

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.

[PATCH AUTOSEL 6.1 14/47] ASoC: da7219: Check for failure reading AAD IRQ events

[Sasha Levin]

From: Dmytro Maluka <dmy@semihalf.com>

[ Upstream commit f0691dc16206f21b13c464434366e2cd632b8ed7 ]

When handling an AAD interrupt, if IRQ events read failed (for example,
due to i2c "Transfer while suspended" failure, i.e. when attempting to
read it while DA7219 is suspended, which may happen due to a spurious
AAD interrupt), the events array contains garbage uninitialized values.
So instead of trying to interprete those values and doing any actions
based on them (potentially resulting in misbehavior, e.g. reporting
bogus events), refuse to handle the interrupt.

[PATCH AUTOSEL 6.1 15/47] ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect

[Sasha Levin]

From: Edson Juliano Drosdeck <edson.drosdeck@gmail.com>

[ Upstream commit 1bc40efdaf4a0ccfdb10a1c8e4b458f4764e8e5f ]

Add a quirk mechanism to allow specifying that active-high jack-detection
should be used on platforms where this info is not available in devicetree.

And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that
jack-detection will work properly on this laptop.

[PATCH AUTOSEL 6.1 16/47] thermal: core: constify params in thermal_zone_device_register

[Sasha Levin]

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

[ Upstream commit 80ddce5f2dbd0e83eadc9f9d373439180d599fe5 ]

Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal zone
parameters structure"), thermal_zone_device_register() allocates a copy
of the tzp argument and callers need not explicitly manage its lifetime.

This means the function no longer cares about the parameter being
mutable, so constify it.

No functional change.

[PATCH AUTOSEL 6.1 18/47] vxlan: generalize vxlan_parse_gpe_hdr and remove unused args

[Sasha Levin]

From: Jiri Benc <jbenc@redhat.com>

[ Upstream commit 17a0a64448b568442a101de09575f81ffdc45d15 ]

The vxlan_parse_gpe_hdr function extracts the next protocol value from
the GPE header and marks GPE bits as parsed.

In order to be used in the next patch, split the function into protocol
extraction and bit marking. The bit marking is meaningful only in
vxlan_rcv; move it directly there.

Rename the function to vxlan_parse_gpe_proto to reflect what it now
does. Remove unused arguments skb and vxflags. Move the function earlier
in the file to allow it to be called from more places in the next patch.

[PATCH AUTOSEL 6.1 19/47] m68k: Fix invalid .section syntax

[Sasha Levin]

From: Ben Hutchings <benh@debian.org>

[ Upstream commit 922a9bd138101e3e5718f0f4d40dba68ef89bb43 ]

gas supports several different forms for .section for ELF targets,
including:
    .section NAME [, "FLAGS"[, @TYPE[,FLAG_SPECIFIC_ARGUMENTS]]]
and:
    .section "NAME"[, #FLAGS...]

In several places we use a mix of these two forms:
    .section NAME, #FLAGS...

A current development snapshot of binutils (2.40.50.20230611) treats
this mixed syntax as an error.

Change to consistently use:
    .section NAME, "FLAGS"
as is used elsewhere in the kernel.

[PATCH AUTOSEL 6.1 20/47] btrfs: remove BUG_ON()'s in add_new_free_space()

[Sasha Levin]

From: Filipe Manana <fdmanana@suse.com>

[ Upstream commit d8ccbd21918fd7fa6ce3226cffc22c444228e8ad ]

At add_new_free_space() we have these BUG_ON()'s that are there to deal
with any failure to add free space to the in memory free space cache.
Such failures are mostly -ENOMEM that should be very rare. However there's
no need to have these BUG_ON()'s, we can just return any error to the
caller and all callers and their upper call chain are already dealing with
errors.

So just make add_new_free_space() return any errors, while removing the
BUG_ON()'s, and returning the total amount of added free space to an
optional u64 pointer argument.

[PATCH AUTOSEL 6.1 21/47] s390/dasd: use correct number of retries for ERP requests

[Sasha Levin]

From: Stefan Haberland <sth@linux.ibm.com>

[ Upstream commit acea28a6b74f458defda7417d2217b051ba7d444 ]

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.

The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Correctly use the number of retries of the original request for ERP
requests.

[PATCH AUTOSEL 6.1 22/47] s390/dasd: fix hanging device after request requeue

[Sasha Levin]

From: Stefan Haberland <sth@linux.ibm.com>

[ Upstream commit 8a2278ce9c25048d999fe1a3561def75d963f471 ]

The DASD device driver has a function to requeue requests to the
blocklayer.
This function is used in various cases when basic settings for the device
have to be changed like High Performance Ficon related parameters or copy
pair settings.

The functions iterates over the device->ccw_queue and also removes the
requests from the block->ccw_queue.
In case the device is started on an alias device instead of the base
device it might be removed from the block->ccw_queue without having it
canceled properly before. This might lead to a hanging device since the
request is no longer on a queue and can not be handled properly.

Fix by iterating over the block->ccw_queue instead of the
device->ccw_queue. This will take care of all blocklayer related requests
and handle them on all associated DASD devices.

load_nls() take a char * parameter, use it to find nls module in list or
construct the module name to load it.

This change make load_nls() take a const parameter, so we don't need do
some cast like this:

        ses->local_nls = load_nls((char *)ctx->local_nls->charset);

[Sasha Levin]

From: Guiting Shen <aarongt.shen@gmail.com>

[ Upstream commit f85739c0b2b0d98a32f5ca4fcc5501d2b76df4f6 ]

The 8K sample parameter of 12.288Mhz main system bus clock doesn't work
because the I2SC_MR.IMCKDIV must not be 0 according to the sama5d2
series datasheet(I2SC Mode Register of Register Summary).

So use the 6.144Mhz instead of 12.288Mhz to support 8K sample.

[PATCH AUTOSEL 6.1 29/47] ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 3da435063777f8d861ba5a165344e3f75f839357 ]

Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
USB Link") has a playback and a capture mixer volume/switch, but they
are fairly broken.  The descriptor reports wrong dB ranges for
playback, and the capture volume/switch don't influence on the actual
recording at all.  Moreover, there seem instabilities in the
connection, and at best, we should disable the runtime PM.

So this ended up with a quirk entry for:
- Correct the playback dB range;
  I picked up some reasonable values but it's a guess work
- Disable the capture mixer;
  it's completely useless and confuses PA/PW
- Suppress get-sample-rate, apply the delay for message handling,
  and suppress the auto-suspend

The behavior of the wheel control on the headset is somehow flaky,
too, but it's an issue of HID.

APMF fn8 can notify EC about the OS slider position change. Add this
capability to the PMF driver so that it can call the APMF fn8 based on
the changes in the Platform profile events.

[PATCH AUTOSEL 6.1 32/47] platform/x86: intel: hid: Always call BTNL ACPI method

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit e3ab18de2b09361d6f0e4aafb9cfd6d002ce43a1 ]

On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE
are only send after the BTNL ACPI method has been called.

Likely more devices need this, so make the BTNL ACPI method unconditional
instead of only doing it on devices with a 5 button array.

Note this also makes the intel_button_array_enable() call in probe()
unconditional, that function does its own priv->array check. This makes
the intel_button_array_enable() call in probe() consistent with the calls
done on suspend/resume which also rely on the priv->array check inside
the function.

[PATCH AUTOSEL 6.1 33/47] platform/x86/intel/hid: Add HP Dragonfly G2 to VGBS DMI quirks

[Sasha Levin]

From: Maxim Mikityanskiy <maxtram95@gmail.com>

[ Upstream commit 7783e97f8558ad7a4d1748922461bc88483fbcdf ]

HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS
method. If VGBS is not called on boot, the firmware sends an initial
0xcd event shortly after calling the BTNL method, but only if the device
is booted in the laptop mode. However, if the device is booted in the
tablet mode and VGBS is not called, there is no initial 0xcc event, and
the input device for SW_TABLET_MODE is not registered up until the user
turns the device into the laptop mode.

Call VGBS on boot on this device to get the initial state of
SW_TABLET_MODE in a reliable way.

Tested with BIOS 1.13.1.

[PATCH AUTOSEL 6.1 36/47] platform/x86: huawei-wmi: Silence ambient light sensor

[Sasha Levin]

From: Konstantin Shelekhin <k.shelekhin@ftml.net>

[ Upstream commit c21733754cd6ecbca346f2adf9b17d4cfa50504f ]

Currently huawei-wmi causes a lot of spam in dmesg on my
Huawei MateBook X Pro 2022:

  ...
  [36409.328463] input input9: Unknown key pressed, code: 0x02c1
  [36411.335104] input input9: Unknown key pressed, code: 0x02c1
  [36412.338674] input input9: Unknown key pressed, code: 0x02c1

  [36416.858706] input input9: Unknown key pressed, code: 0x02c1
  ...

Fix that by ignoring events generated by ambient light sensor.

This issue was reported on GitHub and resolved with the following merge
request:

  https://github.com/aymanbagabas/Huawei-WMI/pull/70

I've contacted the mainter of this repo and he gave me the "go ahead" to
send this patch to the maling list.

[PATCH AUTOSEL 6.1 39/47] drm/amd/display: Exit idle optimizations before attempt to access PHY

[Sasha Levin]

From: Leo Chen <sancchen@amd.com>

[ Upstream commit de612738e9771bd66aeb20044486c457c512f684 ]

[Why & How]
DMUB may hang when powering down pixel clocks due to no dprefclk.

It is fixed by exiting idle optimization before the attempt to access PHY.

[PATCH AUTOSEL 6.1 40/47] ovl: Always reevaluate the file signature for IMA

[Sasha Levin]

From: Eric Snowberg <eric.snowberg@oracle.com>

[ Upstream commit 18b44bc5a67275641fb26f2c54ba7eef80ac5950 ]

Commit db1d1e8b9867 ("IMA: use vfs_getattr_nosec to get the i_version")
partially closed an IMA integrity issue when directly modifying a file
on the lower filesystem.  If the overlay file is first opened by a user
and later the lower backing file is modified by root, but the extended
attribute is NOT updated, the signature validation succeeds with the old
original signature.

Update the super_block s_iflags to SB_I_IMA_UNVERIFIABLE_SIGNATURE to
force signature reevaluation on every file access until a fine grained
solution can be found.

[PATCH AUTOSEL 6.1 41/47] ata: pata_arasan_cf: Use dev_err_probe() instead dev_err() in data_xfer()

From: Minjie Du <duminjie@vivo.com>

[ Upstream commit 4139f992c49356391fb086c0c8ce51f66c26d623 ]

It is possible for dma_request_chan() to return EPROBE_DEFER, which
means acdev->host->dev is not ready yet. At this point dev_err() will
have no output. Use dev_err_probe() instead.

[ Upstream commit f38cb9d9c2045dad16eead4a2e1aedfddd94603b ]

Make the "num_lockers can be only 0 or 1" assumption explicit and
simplify the API by getting rid of output parameters in preparation
for calling get_lock_owner_info() twice before blocklisting.

- we want the exclusive lock type, so test for it directly
- use sscanf() to actually parse the lock cookie and avoid admitting
  invalid handles
- bail if locker has a blank address

[PATCH AUTOSEL 6.1 45/47] staging: fbtft: ili9341: use macro FBTFT_REGISTER_SPI_DRIVER

[Sasha Levin]

From: Raphael Gallais-Pou <rgallaispou@gmail.com>

[ Upstream commit 4912649e1cf0317bf563f91655e04a303cacaf8d ]

Using FBTFT_REGISTER_DRIVER resolves to a NULL struct spi_device_id. This
ultimately causes a warning when the module probes. Fixes it.

[PATCH AUTOSEL 6.1 46/47] security: keys: perform capable check only on privileged operations

[Sasha Levin]

From: Christian Göttsche <cgzones@googlemail.com>

[ Upstream commit 2d7f105edbb3b2be5ffa4d833abbf9b6965e9ce7 ]

If the current task fails the check for the queried capability via
`capable(CAP_SYS_ADMIN)` LSMs like SELinux generate a denial message.
Issuing such denial messages unnecessarily can lead to a policy author
granting more privileges to a subject than needed to silence them.

Reorder CAP_SYS_ADMIN checks after the check whether the operation is
actually privileged.

[PATCH AUTOSEL 6.1 47/47] kprobes: Prohibit probing on CFI preamble symbol

[Sasha Levin]

From: "Masami Hiramatsu (Google)" <mhiramat@kernel.org>

[ Upstream commit de02f2ac5d8cfb311f44f2bf144cc20002f1fbbd ]

Do not allow to probe on "__cfi_" or "__pfx_" started symbol, because those
are used for CFI and not executed. Probing it will break the CFI.
