ca00fa8d73 fbdev: savage: Handle err return when savagefb_check_var failed
commit 6ad959b6703e2c4c5d7af03b4cfd5ff608036339 upstream.

The commit 04e5eac8f3ab("fbdev: savage: Error out if pixclock equals zero")
checks the value of pixclock to avoid divide-by-zero error. However
the function savagefb_probe doesn't handle the error return of
savagefb_check_var. When pixclock is 0, it will cause divide-by-zero error.

bcd9c4ca7a mmc: sdhci-acpi: Disable write protect detection on Toshiba WT10-A
commit ef3eab75e17191e5665f52e64e85bc29d5705a7b upstream.

On the Toshiba WT10-A the microSD slot always reports the card being
write-protected, just like on the Toshiba WT8-B.

Add a DMI quirk to work around this.

83b588c2ae mmc: core: Add mmc_gpiod_set_cd_config() function
commit 63a7cd660246aa36af263b85c33ecc6601bf04be upstream.

Some mmc host drivers may need to fixup a card-detection GPIO's config
to e.g. enable the GPIO controllers builtin pull-up resistor on devices
where the firmware description of the GPIO is broken (e.g. GpioInt with
PullNone instead of PullUp in ACPI DSDT).

Since this is the exception rather then the rule adding a config
parameter to mmc_gpiod_request_cd() seems undesirable, so instead
add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper
to call gpiod_set_config() on the card-detect GPIO acquired through
mmc_gpiod_request_cd().

8d6e1c31a6 media: v4l2-core: hold videodev_lock until dev reg, finishes
commit 1ed4477f2ea4743e7c5e1f9f3722152d14e6eeb1 upstream.

After the new V4L2 device node was registered, some additional
initialization was done before the device node was marked as
'registered'. During the time between creating the device node
and marking it as 'registered' it was possible to open the
device node, which would return -ENODEV since the 'registered'
flag was not yet set.

Hold the videodev_lock mutex from just before the device node
is registered until the 'registered' flag is set. Since v4l2_open
will take the same lock, it will wait until this registration
process is finished. This resolves this race condition.

2b628da8bc media: mxl5xx: Move xpt structures off stack
commit 526f4527545b2d4ce0733733929fac7b6da09ac6 upstream.

When building for LoongArch with clang 18.0.0, the stack usage of
probe() is larger than the allowed 2048 bytes:

  drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than]
   1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg)
        |            ^
  1 warning generated.

This is the result of the linked LLVM commit, which changes how the
arrays of structures in config_ts() get handled with
CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the
above warning in combination with inlining, as config_ts() gets inlined
into probe().

This warning can be easily fixed by moving the array of structures off
of the stackvia 'static const', which is a better location for these
variables anyways because they are static data that is only ever read
from, never modified, so allocating the stack space is wasteful.

This drops the stack usage from 2368 bytes to 256 bytes with the same
compiler and configuration.

First the media device node was created, and if successful it was

an application can open the device node and get an error back

b636627e2b wifi: rtl8xxxu: Fix the TX power of RTL8192CU, RTL8723AU
commit 08b5d052d17a89bb8706b2888277d0b682dc1610 upstream.

Don't subtract 1 from the power index. This was added in commit
2fc0b8e5a17d ("rtl8xxxu: Add TX power base values for gen1 parts")
for unknown reasons. The vendor drivers don't do this.

Also correct the calculations of values written to
REG_OFDM0_X{C,D}_TX_IQ_IMBALANCE. According to the vendor driver,
these are used for TX power training.

With these changes rtl8xxxu sets the TX power of RTL8192CU the same
as the vendor driver.

None of this appears to have any effect on my RTL8192CU device.

88a48b9afd md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING
commit 151f66bb618d1fd0eeb84acb61b4a9fa5d8bb0fa upstream.

Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with
small possibility, the root cause is exactly the same as commit
bed9e27baf52 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"")

However, Dan reported another hang after that, and junxiao investigated
the problem and found out that this is caused by plugged bio can't issue
from raid5d().

Current implementation in raid5d() has a weird dependence:

1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear
   MD_SB_CHANGE_PENDING;
2) raid5d() handles IO in a deadloop, until all IO are issued;
3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared;

This behaviour is introduce before v2.6, and for consequence, if other
context hold 'reconfig_mutex', and md_check_recovery() can't update
super_block, then raid5d() will waste one cpu 100% by the deadloop, until
'reconfig_mutex' is released.

Refer to the implementation from raid1 and raid10, fix this problem by
skipping issue IO if MD_SB_CHANGE_PENDING is still set after
md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex'
is released. Meanwhile, the hang problem will be fixed as well.

a8ed2395db vxlan: Fix regression when dropping packets due to invalid src addresses
commit 1cd4bc987abb2823836cbb8f887026011ccddc8a upstream.

Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address")
has recently been added to vxlan mainly in the context of source
address snooping/learning so that when it is enabled, an entry in the
FDB is not being created for an invalid address for the corresponding
tunnel endpoint.

Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in
that it passed through whichever macs were set in the L2 header. It
turns out that this change in behavior breaks setups, for example,
Cilium with netkit in L3 mode for Pods as well as tunnel mode has been
passing before the change in f58f45c1e5b9 for both vxlan and geneve.
After mentioned change it is only passing for geneve as in case of
vxlan packets are dropped due to vxlan_set_mac() returning false as
source and destination macs are zero which for E/W traffic via tunnel
is totally fine.

Fix it by only opting into the is_valid_ether_addr() check in
vxlan_set_mac() when in fact source address snooping/learning is
actually enabled in vxlan. This is done by moving the check into
vxlan_snoop(). With this change, the Cilium connectivity test suite
passes again for both tunnel flavors.

3df377132b mmc: core: Do not force a retune before RPMB switch
commit 67380251e8bbd3302c64fea07f95c31971b91c22 upstream.

Requesting a retune before switching to the RPMB partition has been
observed to cause CRC errors on the RPMB reads (-EILSEQ).

Since RPMB reads can not be retried, the clients would be directly
affected by the errors.

This commit disables the retune request prior to switching to the RPMB
partition: mmc_retune_pause() no longer triggers a retune before the
pause period begins.

This was verified with the sdhci-of-arasan driver (ZynqMP) configured
for HS200 using two separate eMMC cards (DG4064 and 064GB2). In both
cases, the error was easy to reproduce triggering every few tenths of
reads.

With this commit, systems that were utilizing OP-TEE to access RPMB
variables will experience an enhanced performance. Specifically, when
OP-TEE is configured to employ RPMB as a secure storage solution, it not
only writes the data but also the secure filesystem within the
partition. As a result, retrieving any variable involves multiple RPMB
reads, typically around five.

For context, on ZynqMP, each retune request consumed approximately
8ms. Consequently, reading any RPMB variable used to take at the very
minimum 40ms.

After droping the need to retune before switching to the RPMB partition,
this is no longer the case.

1f985268a4 spi: stm32: Don't warn about spurious interrupts
[ Upstream commit 95d7c452a26564ef0c427f2806761b857106d8c4 ]

The dev_warn to notify about a spurious interrupt was introduced with
the reasoning that these are unexpected. However spurious interrupts
tend to trigger continously and the error message on the serial console
prevents that the core's detection of spurious interrupts kicks in
(which disables the irq) and just floods the console.

811cbba13b net: usb: smsc95xx: fix changing LED_SEL bit value updated from EEPROM
[ Upstream commit 52a2f0608366a629d43dacd3191039c95fef74ba ]

LED Select (LED_SEL) bit in the LED General Purpose IO Configuration
register is used to determine the functionality of external LED pins
(Speed Indicator, Link and Activity Indicator, Full Duplex Link
Indicator). The default value for this bit is 0 when no EEPROM is
present. If a EEPROM is present, the default value is the value of the
LED Select bit in the Configuration Flags of the EEPROM. A USB Reset or
Lite Reset (LRST) will cause this bit to be restored to the image value
last loaded from EEPROM, or to be set to 0 if no EEPROM is present.

While configuring the dual purpose GPIO/LED pins to LED outputs in the
LED General Purpose IO Configuration register, the LED_SEL bit is changed
as 0 and resulting the configured value from the EEPROM is cleared. The
issue is fixed by using read-modify-write approach.

7589085c02 enic: Validate length of nl attributes in enic_set_vf_port
[ Upstream commit e8021b94b0412c37bcc79027c2e382086b6ce449 ]

enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE
is of length PORT_PROFILE_MAX and that the nl attributes
IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.
These attributes are validated (in the function do_setlink in rtnetlink.c)
using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE
as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and
IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation
using the policy is for the max size of the attributes and not on exact
size so the length of these attributes might be less than the sizes that
enic_set_vf_port expects. This might cause an out of bands
read access in the memcpys of the data of these
attributes in enic_set_vf_port.

dcac385c9b nvmet: fix ns enable/disable possible hang
[ Upstream commit f97914e35fd98b2b18fb8a092e0a0799f73afdfe ]

When disabling an nvmet namespace, there is a period where the
subsys->lock is released, as the ns disable waits for backend IO to
complete, and the ns percpu ref to be properly killed. The original
intent was to avoid taking the subsystem lock for a prolong period as
other processes may need to acquire it (for example new incoming
connections).

However, it opens up a window where another process may come in and
enable the ns, (re)intiailizing the ns percpu_ref, causing the disable
sequence to hang.

Solve this by taking the global nvmet_config_sem over the entire configfs
enable/disable sequence.

The assignment of pps_enable is protected by tmreg_lock, but the read
operation of pps_enable is not. So the Coverity tool reports a lock
evasion warning which may cause data race to occur when running in a
multithread environment. Although this issue is almost impossible to
occur, we'd better fix it, at least it seems more logically reasonable,
and it also prevents Coverity from continuing to issue warnings.

a5fff5d0ee regulator: bd71828: Don't overwrite runtime voltages
[ Upstream commit 0f9f7c63c415e287cd57b5c98be61eb320dedcfc ]

Some of the regulators on the BD71828 have common voltage setting for
RUN/SUSPEND/IDLE/LPSR states. The enable control can be set for each
state though.

The driver allows setting the voltage values for these states via
device-tree. As a side effect, setting the voltages for
SUSPEND/IDLE/LPSR will also change the RUN level voltage which is not
desired and can break the system.

The comment in code reflects this behaviour, but it is likely to not
make people any happier. The right thing to do is to allow setting the
enable/disable state at SUSPEND/IDLE/LPSR via device-tree, but to
disallow setting state specific voltages for those regulators.

BUCK1 is a bit different. It only shares the SUSPEND and LPSR state
voltages. The former behaviour of allowing to silently overwrite the
SUSPEND state voltage by LPSR state voltage is also changed here so that
the SUSPEND voltage is prioritized over LPSR voltage.

[ Upstream commit 37f1663c91934f664fb850306708094a324c227c ]

strlcpy() reads the entire source buffer first.  This read may exceed the

read overflows if a source string is not NUL-terminated [1].  In an effort
to remove strlcpy() completely [2], replace strlcpy() here with strscpy().

[ Upstream commit faa4364bef2ec0060de381ff028d1d836600a381 ]

The subtract in this condition is reversed.  The ->length is the length
of the buffer.  The ->bytesused is how many bytes we have copied thus
far.  When the condition is reversed that means the result of the
subtraction is always negative but since it's unsigned then the result
is a very high positive value.  That means the overflow check is never
true.

Additionally, the ->bytesused doesn't actually work for this purpose
because we're not writing to "buf->mem + buf->bytesused".  Instead, the
math to calculate the destination where we are writing is a bit
involved.  You calculate the number of full lines already written,
multiply by two, skip a line if necessary so that we start on an odd
numbered line, and add the offset into the line.

To fix this buffer overflow, just take the actual destination where we
are writing, if the offset is already out of bounds print an error and
return.  Otherwise, write up to buf->length bytes.

7d8a17729e drm/bridge: tc358775: fix support for jeida-18 and jeida-24
[ Upstream commit 30ea09a182cb37c4921b9d477ed18107befe6d78 ]

The bridge always uses 24bpp internally. Therefore, for jeida-18
mapping we need to discard the lowest two bits for each channel and thus
starting with LV_[RGB]2. jeida-24 has the same mapping but uses four
lanes instead of three, with the forth pair transmitting the lowest two
bits of each channel. Thus, the mapping between jeida-18 and jeida-24
is actually the same, except that one channel is turned off (by
selecting the RGB666 format in VPCTRL).

While at it, remove the bogus comment about the hardware default because
the default is overwritten in any case.

Tested with a jeida-18 display (Evervision VGG644804).

a4ea9838b0 drm/msm/dpu: Always flush the slave INTF on the CTL
[ Upstream commit 2b938c3ab0a69ec6ea587bbf6fc2aec3db4a8736 ]

As we can clearly see in a downstream kernel [1], flushing the slave INTF
is skipped /only if/ the PPSPLIT topology is active.

However, when DPU was originally submitted to mainline PPSPLIT was no
longer part of it (seems to have been ripped out before submission), but
this clause was incorrectly ported from the original SDE driver.  Given
that there is no support for PPSPLIT (currently), flushing the slave
INTF should /never/ be skipped (as the `if (ppsplit && !master) goto
skip;` clause downstream never becomes true).

[ Upstream commit 150e792dee9ca8416f3d375e48f2f4d7f701fc6b ]

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
