[PATCH AUTOSEL 6.2 02/60] drm: panel-orientation-quirks: Add quirk for DynaBook K50

[Sasha Levin]

From: Allen Ballway <ballway@chromium.org>

[ Upstream commit a3caf7ea0c3d5872ed0f2c51f5476aee0c47a73a ]

Like the ASUS T100HAN for which there is already a quirk,
the DynaBook K50 has a 800x1280 portrait screen mounted
in the tablet part of a landscape oriented 2-in-1.
Update the quirk to be more generic and apply to this device.

[PATCH AUTOSEL 6.2 05/60] drm/amd/display: Fix potential null-deref in dm_resume

[Sasha Levin]

From: Roman Li <roman.li@amd.com>

[ Upstream commit 7a7175a2cd84b7874bebbf8e59f134557a34161b ]

[Why]
Fixing smatch error:
dm_resume() error: we previously assumed 'aconnector->dc_link' could be null

[How]
Check if dc_link null at the beginning of the loop,
so further checks can be dropped.

dsi_dump_dsi_irqs(), a function used for debugfs prints, has a large

drivers/gpu/drm/omapdrm/dss/dsi.c:1126:1: warning: the frame size of 1060 bytes is larger than 1024 bytes [-Wframe-larger-than=]

As the performance of the function is of no concern, let's allocate the
struct with kmalloc instead.

HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.

Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.

[PATCH AUTOSEL 6.2 08/60] drm/tiny: ili9486: Do not assume 8-bit only SPI controllers

[Sasha Levin]

From: Carlo Caione <ccaione@baylibre.com>

[ Upstream commit 77772e607522daa61f3af74df018559db75c43d6 ]

The pixel data for the ILI9486 is always 16-bits wide and it must be
sent over the SPI bus. When the controller is only able to deal with
8-bit transfers, this 16-bits data needs to be swapped before the
sending to account for the big endian bus, this is on the contrary not
needed when the SPI controller already supports 16-bits transfers.

The decision about swapping the pixel data or not is taken in the MIPI
DBI code by probing the controller capabilities: if the controller only
suppors 8-bit transfers the data is swapped, otherwise it is not.

This swapping/non-swapping is relying on the assumption that when the
controller does support 16-bit transactions then the data is sent
unswapped in 16-bits-per-word over SPI.

The problem with the ILI9486 driver is that it is forcing 8-bit
transactions also for controllers supporting 16-bits, violating the
assumption and corrupting the pixel data.

Align the driver to what is done in the MIPI DBI code by adjusting the
transfer size to the maximum allowed by the SPI controller.

[PATCH AUTOSEL 6.2 09/60] drm/amd/display: Defer DIG FIFO disable after VID stream enable

[Sasha Levin]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[ Upstream commit 2d90a1c054831338d57b39aec4d273cf3e867590 ]

[Why]
On some monitors we see a brief flash of corruption during the
monitor disable sequence caused by FIFO being disabled in the middle
of an active DP stream.

[How]
Wait until DP vid stream is disabled before turning off the FIFO.

The FIFO reset on DP unblank should take care of clearing any FIFO
error, if any.

Use page aligned size to reserve memory usage because page aligned TTM
BO size is used to unreserve memory usage, otherwise no page aligned
size causes memory usage accounting unbalanced.

Change vram_used definition type to int64_t to be able to trigger
WARN_ONCE(adev && adev->kfd.vram_used < 0, "..."), to help debug the
accounting issue with warning and backtrace.

[PATCH AUTOSEL 6.2 13/60] scsi: lpfc: Fix use-after-free KFENCE violation during sysfs firmware write

[Sasha Levin]

From: Justin Tee <justin.tee@broadcom.com>

The driver accessed wr_object pointer data, which was initialized into
mailbox payload memory, after the mailbox object was released back to the
mailbox pool.

Fix by moving the mailbox free calls to the end of the routine ensuring
that we don't reference internal mailbox memory after release.

[PATCH AUTOSEL 6.2 14/60] Revert "fbcon: don't lose the console font across generic->chip driver switch"

[Sasha Levin]

From: Thomas Zimmermann <tzimmermann@suse.de>

[ Upstream commit 12d5796d55f9fd9e4b621003127c99e176665064 ]

This reverts commit ae1287865f5361fa138d4d3b1b6277908b54eac9.

Always free the console font when deinitializing the framebuffer
console. Subsequent framebuffer consoles will then use the default
font. Rely on userspace to load any user-configured font for these
consoles.

Commit ae1287865f53 ("fbcon: don't lose the console font across
generic->chip driver switch") was introduced to work around losing
the font during graphics-device handover. [1][2] It kept a dangling
pointer with the font data between loading the two consoles, which is
fairly adventurous hack. It also never covered cases when the other
consoles, such as VGA text mode, where involved.

The problem has meanwhile been solved in userspace. Systemd comes
with a udev rule that re-installs the configured font when a console
comes up. [3] So the kernel workaround can be removed.

This also removes one of the two special cases triggered by setting
FBINFO_MISC_FIRMWARE in an fbdev driver.

Tested during device handover from efifb and simpledrm to radeon. Udev
reloads the configured console font for the new driver's terminal.

[PATCH AUTOSEL 6.2 15/60] drm/amd: Avoid ASSERT for some message failures

[Sasha Levin]

From: Mario Limonciello <mario.limonciello@amd.com>

[ Upstream commit 3e5019ee67760cd61b2a5fd605e1289c2f92d983 ]

On DCN314 when resuming from s0i3 an ASSERT is shown indicating that
`VBIOSSMC_MSG_SetHardMinDcfclkByFreq` returned `VBIOSSMC_Result_Failed`.

This isn't a driver bug; it's a BIOS/configuration bug. To make this
easier to triage, add an explicit warning when this issue happens.

This matches the behavior utilized for failures with
`VBIOSSMC_MSG_TransferTableDram2Smu` configuration.

From: Brandon Syu <Brandon.Syu@amd.com>

[ Upstream commit 9190d4a263264eabf715f5fc1827da45e3fdc247 ]

[Why]
There is an issue mapping non-allocated location of memory.
It would allocate gpio registers from an array out of bounds.

[How]
Patch correct numbers of bounds for using.

[PATCH AUTOSEL 6.2 18/60] drm/msm/dp: Remove INIT_SETUP delay

[Sasha Levin]

From: Bjorn Andersson <quic_bjorande@quicinc.com>

[ Upstream commit e17af1c9d861dc177e5b56009bd4f71ace688d97 ]

During initalization of the DisplayPort controller an EV_HPD_INIT_SETUP
event is generated, but with a delay of 100 units. This delay existed to
circumvent bug in the QMP combo PHY driver, where if the DP part was
powered up before USB, the common properties would not be properly
initialized - and USB wouldn't work.

This issue was resolved in the recent refactoring of the QMP driver,
so it's now possible to remove this delay.

While there is still a timing dependency in the current implementation,
test indicates that it's now possible to boot with an external display
on USB Type-C and have the display power up, without disconnecting and
reconnecting the cable.

[PATCH AUTOSEL 6.2 19/60] HID: uclogic: Add frame type quirk

[Sasha Levin]

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit 14b71e6ad8ca59dd734c7fa9676f3d60bddee2a9 ]

The report descriptor used to get information about UGEE v2 devices is
incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame
is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of
type UCLOGIC_PARAMS_FRAME_MOUSE.

Here is the original report descriptor:

  0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00
                                     ^ This byte should be 2

Add a quirk to be able to fix the reported frame type.

[PATCH AUTOSEL 6.2 20/60] HID: uclogic: Add battery quirk

[Sasha Levin]

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit f60c377f52de37f8705c5fc6d57737fdaf309ff9 ]

Some UGEE v2 tablets have a wireless version with an internal battery
and their firmware is able to report their battery level.

However, there was not found a field on their descriptor indicating
whether the tablet has battery or not, making it mandatory to classify
such devices through the UCLOGIC_BATTERY_QUIRK quirk.

[PATCH AUTOSEL 6.2 21/60] HID: uclogic: Add support for XP-PEN Deco Pro SW

[Sasha Levin]

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit 7744ca571af55b794595cff2da9d51a26904998f ]

The XP-PEN Deco Pro SW is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse; however, the UCLOGIC_MOUSE_FRAME_QUIRK is
required because it reports an incorrect frame type. Its pen has 2
buttons, supports tilt and pressure.

It can be connected using a USB cable or, to use it in wireless mode,
using a USB Bluetooth dongle. When it is connected in wireless mode the
device battery is used to power it.

All the pieces to support it are already in place. Add its ID and
quirks in order to support the device.

[PATCH AUTOSEL 6.2 23/60] HID: multitouch: Add quirks for flipped axes

[Sasha Levin]

From: Allen Ballway <ballway@chromium.org>

[ Upstream commit a2f416bf062a38bb76cccd526d2d286b8e4db4d9 ]

Certain touchscreen devices, such as the ELAN9034, are oriented
incorrectly and report touches on opposite points on the X and Y axes.
For example, a 100x200 screen touched at (10,20) would report (90, 180)
and vice versa.

This is fixed by adding device quirks to transform the touch points
into the correct spaces, from X -> MAX(X) - X, and Y -> MAX(Y) - Y.

[PATCH AUTOSEL 6.2 25/60] drm: rcar-du: Add quirk for H3 ES1.x pclk workaround

[Sasha Levin]

From: Tomi Valkeinen <tomi.valkeinen+renesas@ideasonboard.com>

[ Upstream commit 4f548bc48a2b4c4e54eecfddb6f7d24aa1b98768 ]

rcar_du_crtc.c does a soc_device_match() in
rcar_du_crtc_set_display_timing() to find out if the SoC is H3 ES1.x, and
if so, apply a workaround.

We will need another H3 ES1.x check in the following patch, so rather than
adding more soc_device_match() calls, let's add a rcar_du_device_info
entry for the ES1, and a quirk flag,
RCAR_DU_QUIRK_H3_ES1_PCLK_STABILITY, for the workaround.

[PATCH AUTOSEL 6.2 26/60] drm: rcar-du: Fix setting a reserved bit in DPLLCR

[Sasha Levin]

From: Tomi Valkeinen <tomi.valkeinen+renesas@ideasonboard.com>

[ Upstream commit 5fbc2f3b91d27e12b614947048764099570cbb55 ]

On H3 ES1.x two bits in DPLLCR are used to select the DU input dot clock
source. These are bits 20 and 21 for DU2, and bits 22 and 23 for DU1. On
non-ES1.x, only the higher bits are used (bits 21 and 23), and the lower
bits are reserved and should be set to 0.

The current code always sets the lower bits, even on non-ES1.x.

For both DU1 and DU2, on all SoC versions, when writing zeroes to those
bits the input clock is DCLKIN, and thus there's no difference between
ES1.x and non-ES1.x.

For DU1, writing 0b10 to the bits (or only writing the higher bit)
results in using PLL0 as the input clock, so in this case there's also
no difference between ES1.x and non-ES1.x.

However, for DU2, writing 0b10 to the bits results in using PLL0 as the
input clock on ES1.x, whereas on non-ES1.x it results in using PLL1. On
ES1.x you need to write 0b11 to select PLL1.

The current code always writes 0b11 to PLCS0 field to select PLL1 on all
SoC versions, which works but causes an illegal (in the sense of not
allowed by the documentation) write to a reserved bit field.

To remove the illegal bit write on PLSC0 we need to handle the input dot
clock selection differently for ES1.x and non-ES1.x.

Add a new quirk, RCAR_DU_QUIRK_H3_ES1_PLL, for this. This way we can
always set the bit 21 on PLSC0 when choosing the PLL as the source
clock, and additionally set the bit 20 when on ES1.x.

[PATCH AUTOSEL 6.2 31/60] habanalabs: fix bug in timestamps registration code

[Sasha Levin]

From: farah kassabri <fkassabri@habana.ai>

[ Upstream commit ac5af9900f82b7034de7c9eb1d70d030ba325607 ]

Protect re-using the same timestamp buffer record before actually
adding it to the to interrupt wait list.
Mark ts buff offset as in use in the spinlock protection area of the
interrupt wait list to avoid getting in the re-use section in
ts_buff_get_kernel_ts_record before adding the node to the list.
this scenario might happen when multiple threads are racing on
same offset and one thread could set data in the ts buff in
ts_buff_get_kernel_ts_record then the other thread takes over
and get to ts_buff_get_kernel_ts_record and we will try
to re-use the same ts buff offset then we will try to
delete a non existing node from the list.

[PATCH AUTOSEL 6.2 32/60] docs/scripts/gdb: add necessary make scripts_gdb step

[Sasha Levin]

From: Jakob Koschel <jkl820.git@gmail.com>

[ Upstream commit 6b219431037bf98c9efd49716aea9b68440477a3 ]

In order to debug the kernel successfully with gdb you need to run
'make scripts_gdb' nowadays.

This was changed with the following commit:

Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb
constants.py")

In order to have a complete guide for beginners this remark
should be added to the offial documentation.

[PATCH AUTOSEL 6.2 34/60] ASoC: soc-compress: Reposition and add pcm_mutex

[Sasha Levin]

From: 강신형 <s47.kang@samsung.com>

[ Upstream commit aa9ff6a4955fdba02b54fbc4386db876603703b7 ]

If panic_on_warn is set and compress stream(DPCM) is started,
then kernel panic occurred because card->pcm_mutex isn't held appropriately.
In the following functions, warning were issued at this line
"snd_soc_dpcm_mutex_assert_held".

static int dpcm_be_connect(struct snd_soc_pcm_runtime *fe,
		struct snd_soc_pcm_runtime *be, int stream)
{
	...
	snd_soc_dpcm_mutex_assert_held(fe);
	...
}

void dpcm_be_disconnect(struct snd_soc_pcm_runtime *fe, int stream)
{
	...
	snd_soc_dpcm_mutex_assert_held(fe);
	...
}

void snd_soc_runtime_action(struct snd_soc_pcm_runtime *rtd,
			    int stream, int action)
{
	...
	snd_soc_dpcm_mutex_assert_held(rtd);
	...
}

int dpcm_dapm_stream_event(struct snd_soc_pcm_runtime *fe, int dir,
	int event)
{
	...
	snd_soc_dpcm_mutex_assert_held(fe);
	...
}

These functions are called by soc_compr_set_params_fe, soc_compr_open_fe
and soc_compr_free_fe
without pcm_mutex locking. And this is call stack.

[PATCH AUTOSEL 6.2 37/60] regulator: s5m8767: Bounds check id indexing into arrays

[Sasha Levin]

From: Kees Cook <keescook@chromium.org>

[ Upstream commit e314e15a0b58f9d051c00b25951073bcdae61953 ]

The compiler has no way to know if "id" is within the array bounds of
the regulators array. Add a check for this and a build-time check that
the regulators and reg_voltage_map arrays are sized the same. Seen with
GCC 13:

../drivers/regulator/s5m8767.c: In function 's5m8767_pmic_probe':
../drivers/regulator/s5m8767.c:936:35: warning: array subscript [0, 36] is outside array bounds of 'struct regulator_desc[37]' [-Warray-bounds=]

[PATCH AUTOSEL 6.2 38/60] Revert "drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled"

[Sasha Levin]

From: Vitaly Prosyak <vitaly.prosyak@amd.com>

[ Upstream commit 39934d3ed5725c5e3570ed1b67f612f1ea60ce03 ]

This reverts commit fac53471d0ea9693d314aa2df08d62b2e7e3a0f8.
The following change: move the drm_dev_unplug call after
amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is
the following: amdgpu_pci_remove calls drm_dev_unregister
and it should be called first to ensure userspace can't access the
device instance anymore. If we call drm_dev_unplug after
amdgpu_driver_unload_kms then we observe IGT PCI software unplug
test failure (kernel hung) for all ASICs. This is how this
regression was found.

After this revert, the following commands do work not, but it would
be fixed in the next commit:
 - sudo modprobe -r amdgpu
 - sudo modprobe amdgpu

[PATCH AUTOSEL 6.2 40/60] gfs2: Improve gfs2_make_fs_rw error handling

[Sasha Levin]

From: Andreas Gruenbacher <agruenba@redhat.com>

[ Upstream commit b66f723bb552ad59c2acb5d45ea45c890f84498b ]

In gfs2_make_fs_rw(), make sure to call gfs2_consist() to report an
inconsistency and mark the filesystem as withdrawn when
gfs2_find_jhead() fails.

At the end of gfs2_make_fs_rw(), when we discover that the filesystem
has been withdrawn, make sure we report an error.  This also replaces
the gfs2_withdrawn() check after gfs2_find_jhead().

[PATCH AUTOSEL 6.2 41/60] hwmon: (coretemp) Simplify platform device handling

[Sasha Levin]

From: Robin Murphy <robin.murphy@arm.com>

[ Upstream commit 6d03bbff456befeccdd4d663177c4d6c75d0c4ff ]

Coretemp's platform driver is unconventional. All the real work is done
globally by the initcall and CPU hotplug notifiers, while the "driver"
effectively just wraps an allocation and the registration of the hwmon
interface in a long-winded round-trip through the driver core.  The whole
logic of dynamically creating and destroying platform devices to bring
the interfaces up and down is error prone, since it assumes
platform_device_add() will synchronously bind the driver and set drvdata
before it returns, thus results in a NULL dereference if drivers_autoprobe
is turned off for the platform bus. Furthermore, the unusual approach of
doing that from within a CPU hotplug notifier, already commented in the
code that it deadlocks suspend, also causes lockdep issues for other
drivers or subsystems which may want to legitimately register a CPU
hotplug notifier from a platform bus notifier.

All of these issues can be solved by ripping this unusual behaviour out
completely, simply tying the platform devices to the lifetime of the
module itself, and directly managing the hwmon interfaces from the
hotplug notifiers. There is a slight user-visible change in that
/sys/bus/platform/drivers/coretemp will no longer appear, and
/sys/devices/platform/coretemp.n will remain present if package n is
hotplugged off, but hwmon users should really only be looking for the
presence of the hwmon interfaces, whose behaviour remains unchanged.

[PATCH AUTOSEL 6.2 42/60] hwmon: (nct6775) Directly call ASUS ACPI WMI method

[Sasha Levin]

From: Denis Pauk <pauk.denis@gmail.com>

[ Upstream commit c3b3747d02f571da2543e719066a50dd966989d8 ]

New ASUS B650/B660/X670 boards firmware have not exposed WMI monitoring
GUID  and entrypoint method WMBD could be implemented for different device
UID.

Implement the direct call to entrypoint method for monitoring the device
UID of B550/X570 boards.

This commit adds such boards to the monitoring list with new ACPI device
UID.

[PATCH AUTOSEL 6.2 44/60] pinctrl: at91: use devm_kasprintf() to avoid potential leaks

[Sasha Levin]

From: Claudiu Beznea <claudiu.beznea@microchip.com>

[ Upstream commit 1c4e5c470a56f7f7c649c0c70e603abc1eab15c4 ]

Use devm_kasprintf() instead of kasprintf() to avoid any potential
leaks. At the moment drivers have no remove functionality thus
there is no need for fixes tag.

From: Wesley Chalmers <Wesley.Chalmers@amd.com>

[ Upstream commit 4f1b5e739dfd1edde33329e3f376733a131fb1ff ]

[WHY]
Writing to DRR registers such as OTG_V_TOTAL_MIN on the same frame as a
pipe commit can cause underflow.

[HOW]
Defer all DPP adjustment requests till optimized_required is false.

[PATCH AUTOSEL 6.2 47/60] scsi: snic: Fix memory leak with using debugfs_lookup()

[Sasha Levin]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit ad0e4e2fab928477f74d742e6e77d79245d3d3e7 ]

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic at
once.

[PATCH AUTOSEL 6.2 48/60] scsi: ufs: core: Fix device management cmd timeout flow

[Sasha Levin]

From: Mason Zhang <Mason.Zhang@mediatek.com>

[ Upstream commit 36822124f9de200cedc2f42516301b50d386a6cd ]

In the UFS error handling flow, the host will send a device management cmd
(NOP OUT) to the device for link recovery. If this cmd times out and
clearing the doorbell fails, ufshcd_wait_for_dev_cmd() will do nothing and
return. hba->dev_cmd.complete struct is not set to NULL.

When this happens, if cmd has been completed by device, then we will call
complete() in __ufshcd_transfer_req_compl(). Because the complete struct is
allocated on the stack, the following crash will occur:

[PATCH AUTOSEL 6.2 50/60] drm/amd/display: Move DCN314 DOMAIN power control to DMCUB

[Sasha Levin]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[ Upstream commit e383b12709e32d6494c948422070c2464b637e44 ]

[Why]
DOMAIN power gating control is now required to be done via firmware
due to interlock with other power features. This is to avoid
intermittent issues in the LB memories.

[How]
If the firmware supports the command then use the new firmware as
the sequence can avoid potential display corruption issues.

The command will be ignored on firmware that does not support DOMAIN
power control and the pipes will remain always on - frequent PG cycling
can cause the issue to occur on the old sequence, so we should avoid it.

[PATCH AUTOSEL 6.2 54/60] drm/amd/display: disable SubVP + DRR to prevent underflow

[Sasha Levin]

From: Aurabindo Pillai <aurabindo.pillai@amd.com>

[ Upstream commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0 ]

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.

Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.

If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:

amdgpu.dcfeaturemask=0x200

[PATCH AUTOSEL 6.2 57/60] nfsd: zero out pointers after putting nfsd_files on COPY setup error

From: Jeff Layton <jlayton@kernel.org>

[ Upstream commit 1f0001d43d0c0ac2a19a34a914f6595ad97cbc1d ]

At first, I thought this might be a source of nfsd_file overputs, but
the current callers seem to avoid an extra put when nfsd4_verify_copy
returns an error.

Still, it's "bad form" to leave the pointers filled out when we don't
have a reference to them anymore, and that might lead to bugs later.
Zero them out as a defensive coding measure.

[PATCH AUTOSEL 6.2 58/60] nfsd: clean up potential nfsd_file refcount leaks in COPY codepath

[Sasha Levin]

From: Jeff Layton <jlayton@kernel.org>

[ Upstream commit 6ba434cb1a8d403ea9aad1b667c3ea3ad8b3191f ]

There are two different flavors of the nfsd4_copy struct. One is
embedded in the compound and is used directly in synchronous copies. The
other is dynamically allocated, refcounted and tracked in the client
struture. For the embedded one, the cleanup just involves releasing any
nfsd_files held on its behalf. For the async one, the cleanup is a bit
more involved, and we need to dequeue it from lists, unhash it, etc.

There is at least one potential refcount leak in this code now. If the
kthread_create call fails, then both the src and dst nfsd_files in the
original nfsd4_copy object are leaked.

The cleanup in this codepath is also sort of weird. In the async copy
case, we'll have up to four nfsd_file references (src and dst for both
flavors of copy structure). They are both put at the end of
nfsd4_do_async_copy, even though the ones held on behalf of the embedded
one outlive that structure.

Change it so that we always clean up the nfsd_file refs held by the
embedded copy structure before nfsd4_copy returns. Rework
cleanup_async_copy to handle both inter and intra copies. Eliminate
nfsd4_cleanup_intra_ssc since it now becomes a no-op.

[PATCH AUTOSEL 6.2 59/60] nfsd: don't hand out delegation on setuid files being opened for write

[Sasha Levin]

From: Jeff Layton <jlayton@kernel.org>

[ Upstream commit 826b67e6376c2a788e3a62c4860dcd79500a27d5 ]

We had a bug report that xfstest generic/355 was failing on NFSv4.0.
This test sets various combinations of setuid/setgid modes and tests
whether DIO writes will cause them to be stripped.

What I found was that the server did properly strip those bits, but
the client didn't notice because it held a delegation that was not
recalled. The recall didn't occur because the client itself was the
one generating the activity and we avoid recalls in that case.

Clearing setuid bits is an "implicit" activity. The client didn't
specifically request that we do that, so we need the server to issue a
CB_RECALL, or avoid the situation entirely by not issuing a delegation.

The easiest fix here is to simply not give out a delegation if the file
is being opened for write, and the mode has the setuid and/or setgid bit
set. Note that there is a potential race between the mode and lease
being set, so we test for this condition both before and after setting
the lease.

This patch fixes generic/355, generic/683 and generic/684 for me. (Note
that 355 fails only on v4.0, and 683 and 684 require NFSv4.2 to run and
fail).
