-Subject: ARC: define ASM_NL and __ALIGN(_STR) outside #ifdef __ASSEMBLY__
- guard
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-[ Upstream commit 92e2921eeafdfca9acd9b83f07d2b7ca099bac24 ]
-
-ASM_NL is useful not only in *.S files but also in .c files for using
-inline assembler in C code.
-
-On ARC, however, ASM_NL is evaluated inconsistently. It is expanded to
-a backquote (`) in *.S files, but a semicolon (;) in *.c files because
-arch/arc/include/asm/linkage.h defines it inside #ifdef __ASSEMBLY__,
-so the definition for C code falls back to the default value defined in
-include/linux/linkage.h.
-
-If ASM_NL is used in inline assembler in .c files, it will result in
-wrong assembly code because a semicolon is not an instruction separator,
-but the start of a comment for ARC.
-
-Move ASM_NL (also __ALIGN and __ALIGN_STR) out of the #ifdef.
-
-Fixes: 9df62f054406 ("arch: use ASM_NL instead of ';' for assembler new line character in the macro")

-
-From: Marek Vasut <marex@denx.de>
-
-[ Upstream commit e3f2778b1b6ced649bffdc7cbb05b80bb92f2108 ]
-
-The audio routing flow is not correct, the flow should be from source
-(second element in the pair) to sink (first element in the pair). The
-flow now is from "HP_OUT" to "Playback", where "Playback" is source
-and "HP_OUT" is sink, i.e. the direction is swapped and there is no
-direct link between the two either.
-
-Fill in the correct routing, where "HP_OUT" supplies the "Headphone Jack",
-"Line In Jack" supplies "LINE_IN" input, "Microphone Jack" supplies "MIC_IN"
-input and "Mic Bias" supplies "Microphone Jack".

-
-From: Marek Vasut <marex@denx.de>
-
-[ Upstream commit 9660efc2af37f3c12dc6e6a5511ad99e0addc297 ]
-
-The ethernet MAC EEPROM is not populated on the SoM itself, it has to be
-populated on each carrier board. Move the EEPROM into the correct place
-in DTs, i.e. the carrier board DTs. Add label to the EEPROM too.

-Subject: ARM/gpio: Push OMAP2 quirk down into TWL4030 driver
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit d5f4fa60d63aa54ae33339895b88d8932b6037ed ]
-
-The TWL4030 GPIO driver has a custom platform data .set_up()
-callback to call back into the platform and do misc stuff such
-as hog and export a GPIO for WLAN PWR on a specific OMAP3 board.
-
-Avoid all the kludgery in the platform data and the boardfile
-and just put the quirks right into the driver. Make it
-conditional on OMAP3.
-
-I think the exported GPIO is used by some kind of userspace
-so ordinary DTS hogs will probably not work.

-Subject: ARM/mfd/gpio: Fixup TPS65010 regression on OMAP1 OSK1
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit c32c81f3dbdfd68f6ab20a29ad86f811aed36e4e ]
-
-Aaro reports problems on the OSK1 board after we altered
-the dynamic base for GPIO allocations.
-
-It appears this happens because the OMAP driver now
-allocates GPIO numbers dynamically, so all that is
-references by number is a bit up in the air.
-
-Let's bite the bullet and try to just move the gpio_chip
-in the tps65010 MFD driver over to using dynamic allocations.
-Alter everything in the OSK1 board file to use a GPIO
-descriptor table and lookups.
-
-Utilize the NULL device to define some board-specific
-GPIO lookups and use these to immediately look up the
-same GPIOs, convert to IRQ numbers and pass as resources
-to the devices. This is ugly but should work.
-
-The .setup() callback for tps65010 was used for some GPIO
-hogging, but since the OSK1 is the only user in the entire
-kernel we can alter the signatures to something that
-is helpful and make a clean transition.

-Subject: ARM/mmc: Convert old mmci-omap to GPIO descriptors
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit e519f0bb64efc2c9c8b67bb2d114dda458bdc34d ]
-
-A recent change to the OMAP driver making it use a dynamic GPIO
-base created problems with some old OMAP1 board files, among
-them Nokia 770, SX1 and also the OMAP2 Nokia n8x0.
-
-Fix up all instances of GPIOs being used for the MMC driver
-by pushing the handling of power, slot selection and MMC
-"cover" into the driver as optional GPIOs.
-
-This is maybe not the most perfect solution as the MMC
-framework have some central handlers for some of the
-stuff, but it at least makes the situtation better and
-solves the immediate issue.

-Subject: ARM/musb: omap2: Remove global GPIO numbers from TUSB6010
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit 8e0285ab95a9baf374f2c13eb152221c8ecb3f28 ]
-
-The TUSB6010 (MUSB) device is picking up some GPIO lines
-hardcoded by number and passing on to the TUSB6010 device
-when registering it.
-
-Instead of nasty workarounds, provide a GPIO descriptor
-table and then make the TUSB6010 MUSB glue driver pick up
-the GPIO lines directly, convert it to an IRQ and pass down
-to the MUSB driver. OMAP2 is the only system using the
-TUSB6010.
-
-Stash the GPIO descriptors in the glue layer and use
-then to power up and down the TUSB6010 on-demand, instead
-of using boardfile callbacks.
-
-Since the OMAP2 boards are the only boards using the
-.set_power() and .board_set_power() callbacks, we can
-just delete them as the power is now handled directly
-in the TUSB6010 glue code.

-Subject: ARM: omap1: Remove reliance on GPIO numbers from SX1
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit 480c82daa3e41873421dc2c9e2918ad7e21d7a0b ]
-
-It appears this happens because the OMAP driver now
-allocates GPIO numbers dynamically, so all that is
-references by number is a bit up in the air.
-
-Utilize the NULL device to define some board-specific
-GPIO lookups and use these to immediately look up the
-same GPIOs, convert to IRQ numbers and pass as resources
-to the devices. This is ugly but should work.

-
-omap2 contains a hack to define tick_broadcast() on non-SMP
-configurations in place of the normal SMP definition. This one
-causes a warning because of a missing prototype:

-
-[ Upstream commit 078dc5194c0ac1b8e2fc088be2168a1104e16f72 ]
-
-The OMAP2 platform data quirk is using the global GPIO numberspace
-to obtain two WLAN GPIOs to drive power and xcvr reset GPIO
-lines during start-up.
-
-Rewrite the quirk to use a GPIO descriptor table so we avoid using
-global GPIO numbers.
-
-This gets rid of the final dependency on the legacy <linux/gpio.h>
-header from the OMAP2/3 platforms.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-
-[ Upstream commit a4366b5695c984b8a3fc8b31de9e758c8f6d1aed ]
-
-The capacity-dmips-mhz parameter was miscalculated: this SoC runs
-the first (Cortex-A55) cluster at a maximum of 2000MHz and the
-second (Cortex-A76) cluster at a maximum of 2200MHz.
-
-In order to calculate the right capacity-dmips-mhz, the following
-test was performed:
-1. CPUFREQ governor was set to 'performance' on both clusters
-2. Ran dhrystone with 500000000 iterations for 10 times on each cluster
-3. Calculated the mean result for each cluster
-4. Calculated DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz
-5. Scaled results to 1024:
- result_c0 = dmips_mhz_c0 / dmips_mhz_c1 * 1024
-
-The mean results for this SoC are:
-Cluster 0 (LITTLE): 12016411 Dhry/s
-Cluster 1 (BIG): 31702034 Dhry/s
-
-The calculated scaled results are:
-Cluster 0: 426.953226899238 (rounded to 427)
-Cluster 1: 1024

-
-From: Robert Marko <robert.marko@sartura.hr>
-
-[ Upstream commit 70be83708c925b3f72c508e4756e48ad2330c830 ]
-
-PSCI is not implemented on SparX-5 at all, there is no ATF and U-boot that
-is shipped does not implement it as well.
-
-I have tried flashing the latest BSP 2022.12 U-boot which did not work.
-After contacting Microchip, they confirmed that there is no ATF for the
-SoC nor PSCI implementation which is unfortunate in 2023.
-
-So, disable PSCI as otherwise kernel crashes as soon as it tries probing
-PSCI with, and the crash is only visible if earlycon is used.
-
-Since PSCI is not implemented, switch core bringup to use spin-tables
-which are implemented in the vendor U-boot and actually work.
-
-Tested on PCB134 with eMMC (VSC5640EV).

-
-From: Stephan Gerhold <stephan@gerhold.net>
-
-[ Upstream commit 5500f823db38db073d30557af159b77fb1f2bf26 ]
-
-The 96Boards specification expects a 1.8V power rail on the low-speed
-expansion connector that is able to provide at least 0.18W / 100 mA.
-According to the DB410c hardware user manual this is done by connecting
-both L15 and L16 in parallel with up to 55mA each (for 110 mA total) [1].
-
-Unfortunately the current regulator setup in the DB410c device tree
-does not implement the specification correctly and only provides 5 mA:
-
- - Only L15 is marked always-on, so L16 is never enabled.
- - Without specifying a load the regulator is put into LPM where
- it can only provide 5 mA.
-
-Fix this by:
-
- - Adding proper voltage constraints for L16.
- - Making L16 always-on.
- - Adding regulator-system-load for both L15 and L16. 100 mA should be
- available in total, so specify 50 mA for each. (The regulator
- hardware can only be in normal (55 mA) or low-power mode (5 mA) so
- this will actually result in the expected 110 mA total...)

-
-From: Stephan Gerhold <stephan@gerhold.net>
-
-[ Upstream commit e27654df20d77ad7549a3cf6739ebaa3aa59a088 ]
-
-For some reason DB410c has completely bogus regulator constraints that
-actually just correspond to the programmable voltages which are already
-provided by the regulator driver. Some of them are not just outside the
-recommended operating conditions of the APQ8016E SoC but even exceed
-the absolute maximum ratings, potentially risking permanent device
-damage.
-
-In practice it's not quite as dangerous thanks to the RPM firmware:
-It turns out that it has its own voltage constraints and silently
-clamps all regulator requests. For example, requesting 3.3V for L5
-(allowed by the current regulator constraints!) still results in 1.8V
-being programmed in the actual regulator hardware.
-
-Experimentation with various voltages shows that the internal RPM
-voltage constraints roughly correspond to the safe "specified range"
-in the PM8916 Device Specification (rather than the "programmable
-range" used inside apq8016-sbc.dtsi right now).
-
-Combine those together with some fixed voltages used in the old
-msm-3.10 device tree from Qualcomm to give DB410c some actually valid
-voltage constraints.

-Subject: arm64: dts: qcom: sm8250-edo: Panel framebuffer is 2.5k instead of 4k
-
-From: Marijn Suijten <marijn.suijten@somainline.org>
-
-[ Upstream commit 223ce29c8b7e5b00f01a68387aabeefd77d97f06 ]
-
-The framebuffer configuration for edo pdx203, written in edo dtsi (which
-is overwritten in pdx206 dts for its smaller panel) has to use a
-1096x2560 configuration as this is what the panel (and framebuffer area)
-has been initialized to. Downstream userspace also has access to (and
-uses) this 2.5k mode by default, and only switches the panel to 4k when
-requested.
-
-This is similar to commit be8de06dc397 ("arm64: dts: qcom:
-sm8150-kumano: Panel framebuffer is 2.5k instead of 4k") which fixed the
-same for the previous generation Sony platform.

-Subject: arm64: dts: rockchip: Assign ES8316 MCLK rate on rk3588-rock-5b
-
-From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>
-
-[ Upstream commit 28ee08cef4f838c343013330a3cd12674c4dd113 ]
-
-The I2S0_8CH_MCLKOUT clock rate on Rock 5B board defaults to 12 MHz and
-it is used to provide the master clock (MCLK) for the ES8316 audio
-codec.
-
-On sound card initialization, this limits the allowed sample rates
-according to the MCLK/LRCK ratios supported by the codec, which results
-in the following non-standard rates: 15625, 30000, 31250, 46875.
-
-Hence, the very first access of the sound card fails:
-
- Broken configuration for playback: no configurations available: Invalid argument
- Setting of hwparams failed: Invalid argument
-
-However, all subsequent attempts will succeed, as the audio graph card
-will request a correct clock frequency, based on the stream sample rate
-and the multiplication factor.
-
-Assign MCLK to 12.288 MHz, which allows the codec to advertise most of
-the standard sample rates.

-wkup_pmx splits into multiple regions. Like
-
- wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12)
- wkup_pmx1 -> 2 pins (WKUP_PADCONFIG 14 - 15)
- wkup_pmx2 -> 59 pins (WKUP_PADCONFIG 26 - 84)
- wkup_pmx3 -> 8 pins (WKUP_PADCONFIG 93 - 100)
-
-With this split, pin offset needs to be adjusted to
-match with new pmx for all pins above wkup_pmx0.
-
-Example a pin under wkup_pmx1 should start from 0 instead of
-old offset(0x38 WKUP_PADCONFIG 14 offset)

-[ Upstream commit 155e7635ed1f3814d94d12556a3a0fed41d05b76 ]
-
-Mailbox nodes are now disabled by default. The BeagleBoard AI64 DT
-addition went in at around the same time and must have missed that
-change so the mailboxes are not re-enabled. Do that here.

-
-[ Upstream commit c10a9df30e3401bd5a5ee43f1afd6c2b2ca75ad7 ]
-
-main_i2c0 is aliased as i2c0 which creates a problem for u-boot R5
-SPL attempting to reuse the same definition in the common board
-detection logic as it looks for the first i2c instance as the bus on
-which to detect the eeprom to understand the board variant involved.
-Switch main_i2c0 to i2c3 alias allowing us to introduce wkup_i2c0
-and potentially space for mcu_i2c instances in the gap for follow on
-patches.

-Subject: arm64: sme: Use STR P to clear FFR context field in streaming SVE
- mode
-
-From: Will Deacon <will@kernel.org>
-
-[ Upstream commit 893b24181b4c4bf1fa2841b1ed192e5413a97cb1 ]
-
-The FFR is a predicate register which can vary between 16 and 256 bits
-in size depending upon the configured vector length. When saving the
-SVE state in streaming SVE mode, the FFR register is inaccessible and
-so commit 9f5848665788 ("arm64/sve: Make access to FFR optional") simply
-clears the FFR field of the in-memory context structure. Unfortunately,
-it achieves this using an unconditional 8-byte store and so if the SME
-vector length is anything other than 64 bytes in size we will either
-fail to clear the entire field or, worse, we will corrupt memory
-immediately following the structure. This has led to intermittent kfence
-splats in CI [1] and can trigger kmalloc Redzone corruption messages
-when running the 'fp-stress' kselftest:
-
- | =============================================================================
- | BUG kmalloc-1k (Not tainted): kmalloc Redzone overwritten
- | -----------------------------------------------------------------------------
- |
- | 0xffff000809bf1e22-0xffff000809bf1e27 @offset=7714. First byte 0x0 instead of 0xcc
- | Allocated in do_sme_acc+0x9c/0x220 age=2613 cpu=1 pid=531
- | __kmalloc+0x8c/0xcc
- | do_sme_acc+0x9c/0x220
- | ...
-
-Replace the 8-byte store with a store of a predicate register which has
-been zero-initialised with PFALSE, ensuring that the entire field is
-cleared in memory.

-Subject: ASoC: es8316: Do not set rate constraints for unsupported MCLKs
-
-From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>
-
-[ Upstream commit 60413129ee2b38a80347489270af7f6e1c1de4d0 ]
-
-When using the codec through the generic audio graph card, there are at
-least two calls of es8316_set_dai_sysclk(), with the effect of limiting
-the allowed sample rates according to the MCLK/LRCK ratios supported by
-the codec:
-
-1. During audio card setup, to set the initial MCLK - see
- asoc_simple_init_dai().
-
-2. Before opening a stream, to update MCLK, according to the stream
- sample rate and the multiplication factor - see
- asoc_simple_hw_params().
-
-In some cases the initial MCLK might be set to a frequency that doesn't
-match any of the supported ratios, e.g. 12287999 instead of 12288000,
-which is only 1 Hz below the supported clock, as that is what the
-hardware reports. This creates an empty list of rate constraints, which
-is further passed to snd_pcm_hw_constraint_list() via
-es8316_pcm_startup(), and causes the following error on the very first
-access of the sound card:
-
- $ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav
- Broken configuration for playback: no configurations available: Invalid argument
- Setting of hwparams failed: Invalid argument
-
-Note that all subsequent retries succeed thanks to the updated MCLK set
-at point 2 above, which uses a computed frequency value instead of a
-reading from the hardware registers. Normally this would have mitigated
-the issue, but es8316_pcm_startup() executes before the 2nd call to
-es8316_set_dai_sysclk(), hence it cannot make use of the updated
-constraints.
-
-Since es8316_pcm_hw_params() performs anyway a final validation of MCLK
-against the stream sample rate and the supported MCLK/LRCK ratios, fix
-the issue by ensuring that sysclk_constraints list is only set when at
-least one supported sample rate is autodetected by the codec.

-Subject: ASoC: es8316: Increment max value for ALC Capture Target Volume
- control
-
-From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>
-
-[ Upstream commit 6f073429037cd79d7311cd8236311c53f5ea8f01 ]
-
-The following error occurs when trying to restore a previously saved
-ALSA mixer state (tested on a Rock 5B board):
-
- $ alsactl --no-ucm -f /tmp/asound.state store hw:Analog
- $ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog
- alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument
-
-According to ES8316 datasheet, the register at address 0x2B, which is
-related to the above mixer control, contains by default the value 0xB0.
-Considering the corresponding ALC target bits (ALCLVL) are 7:4, the
-control is initialized with 11, which is one step above the maximum
-value allowed by the driver:
-
- ALCLVL | dB gain
- -------+--------
- 0000 | -16.5
- 0001 | -15.0
- 0010 | -13.5
- .... | .....
- 0111 | -6.0
- 1000 | -4.5
- 1001 | -3.0
- 1010 | -1.5
- .... | .....
- 1111 | -1.5
-
-The tests performed using the VU meter feature (--vumeter=TYPE) of
-arecord/aplay confirm the specs are correct and there is no measured
-gain if the 1011-1111 range would have been mapped to 0 dB:
-
- dB gain | VU meter %
- --------+-----------
- -6.0 | 30-31
- -4.5 | 35-36
- -3.0 | 42-43
- -1.5 | 50-51
- 0.0 | 50-51
-
-Increment the max value allowed for ALC Capture Target Volume control,
-so that it matches the hardware default. Additionally, update the
-related TLV to prevent an artificial extension of the dB gain range.

-Subject: blk-cgroup: Reinit blkg_iostat_set after clearing in
- blkcg_reset_stats()
-
-From: Waiman Long <longman@redhat.com>
-
-[ Upstream commit 3d2af77e31ade05ff7ccc3658c3635ec1bea0979 ]
-
-When blkg_alloc() is called to allocate a blkcg_gq structure
-with the associated blkg_iostat_set's, there are 2 fields within
-blkg_iostat_set that requires proper initialization - blkg & sync.
-The former field was introduced by commit 3b8cc6298724 ("blk-cgroup:
-Optimize blkcg_rstat_flush()") while the later one was introduced by
-commit f73316482977 ("blk-cgroup: reimplement basic IO stats using
-cgroup rstat").
-
-Unfortunately those fields in the blkg_iostat_set's are not properly
-re-initialized when they are cleared in v1's blkcg_reset_stats(). This
-can lead to a kernel panic due to NULL pointer access of the blkg
-pointer. The missing initialization of sync is less problematic and
-can be a problem in a debug kernel due to missing lockdep initialization.
-
-Fix these problems by re-initializing them after memory clearing.

-
-From: Ming Lei <ming.lei@redhat.com>
-
-[ Upstream commit 2293cae703cda162684ae966db6b1b4a11b5e88f ]
-
-In case of real io scheduler, q->elevator is set, so blk_mq_run_hw_queue()
-may just check if scheduler queue has request to dispatch, see
-__blk_mq_sched_dispatch_requests(). Then IO hang may be caused because
-all passthorugh requests may stay in sw queue.
-
-And any passthrough request should have been inserted to hctx->dispatch
-always.

-

-
-Passthrough requests should never be queued to the I/O scheduler,

-schedulers might require req->bio to be always valid.

-We never let passthrough requests insert into the scheduler before

-Subject: blk-mq: fix potential io hang by wrong 'wake_batch'
-
-From: Yu Kuai <yukuai3@huawei.com>
-
-[ Upstream commit 4f1731df60f9033669f024d06ae26a6301260b55 ]
-
-In __blk_mq_tag_busy/idle(), updating 'active_queues' and calculating
-'wake_batch' is not atomic:
-
-t1: t2:
-_blk_mq_tag_busy blk_mq_tag_busy
-inc active_queues
-// assume 1->2
- inc active_queues
- // 2 -> 3
- blk_mq_update_wake_batch
- // calculate based on 3
-blk_mq_update_wake_batch
-/* calculate based on 2, while active_queues is actually 3. */
-
-Fix this problem by protecting them wih 'tags->lock', this is not a hot
-path, so performance should not be concerned. And now that all writers
-are inside the lock, switch 'actives_queues' from atomic to unsigned
-int.

-
-Commit 99d055b4fd4b ("block: remove per-disk debugfs files in
-blk_unregister_queue") moves blk_trace_shutdown() from
-blk_release_queue() to blk_unregister_queue(), this is safe if blktrace
-is created through sysfs, however, there is a regression in corner
-case.
-
-blktrace can still be enabled after del_gendisk() through ioctl if
-the disk is opened before del_gendisk(), and if blktrace is not shutdown
-through ioctl before closing the disk, debugfs entries will be leaked.
-
-Fix this problem by shutdown blktrace in disk_release(), this is safe
-because blk_trace_remove() is reentrant.

-Subject: block/rq_qos: protect rq_qos apis with a new lock
-
-From: Yu Kuai <yukuai3@huawei.com>
-
-[ Upstream commit a13bd91be22318768d55470cbc0b0f4488ef9edf ]
-
-commit 50e34d78815e ("block: disable the elevator int del_gendisk")
-move rq_qos_exit() from disk_release() to del_gendisk(), this will
-introduce some problems:
-
-1) If rq_qos_add() is triggered by enabling iocost/iolatency through
- cgroupfs, then it can concurrent with del_gendisk(), it's not safe to
- write 'q->rq_qos' concurrently.
-
-2) Activate cgroup policy that is relied on rq_qos will call
- rq_qos_add() and blkcg_activate_policy(), and if rq_qos_exit() is
- called in the middle, null-ptr-dereference will be triggered in
- blkcg_activate_policy().
-
-3) blkg_conf_open_bdev() can call blkdev_get_no_open() first to find the
- disk, then if rq_qos_exit() from del_gendisk() is done before
- rq_qos_add(), then memory will be leaked.
-
-This patch add a new disk level mutex 'rq_qos_mutex':
-
-1) The lock will protect rq_qos_exit() directly.
-
-2) For wbt that doesn't relied on blk-cgroup, rq_qos_add() can only be
- called from disk initialization for now because wbt can't be
- destructed until rq_qos_exit(), so it's safe not to protect wbt for
- now. Hoever, in case that rq_qos dynamically destruction is supported
- in the furture, this patch also protect rq_qos_add() from wbt_init()
- directly, this is enough because blk-sysfs already synchronize
- writers with disk removal.
-
-3) For iocost and iolatency, in order to synchronize disk removal and
- cgroup configuration, the lock is held after blkdev_get_no_open()
- from blkg_conf_open_bdev(), and is released in blkg_conf_exit().
- In order to fix the above memory leak, disk_live() is checked after
- holding the new lock.

-Subject: bpf: Don't EFAULT for {g,s}setsockopt with wrong optlen
-
-From: Stanislav Fomichev <sdf@google.com>
-
-[ Upstream commit 29ebbba7d46136cba324264e513a1e964ca16c0a ]
-
-With the way the hooks implemented right now, we have a special
-condition: optval larger than PAGE_SIZE will expose only first 4k into
-BPF; any modifications to the optval are ignored. If the BPF program
-doesn't handle this condition by resetting optlen to 0,
-the userspace will get EFAULT.
-
-The intention of the EFAULT was to make it apparent to the
-developers that the program is doing something wrong.
-However, this inadvertently might affect production workloads
-with the BPF programs that are not too careful (i.e., returning EFAULT
-for perfectly valid setsockopt/getsockopt calls).
-
-Let's try to minimize the chance of BPF program screwing up userspace
-by ignoring the output of those BPF programs (instead of returning
-EFAULT to the userspace). pr_info_once those cases to
-the dmesg to help with figuring out what's going wrong.

-Subject: bpf: encapsulate precision backtracking bookkeeping
-
-From: Andrii Nakryiko <andrii@kernel.org>
-
-[ Upstream commit 407958a0e980b9e1842ab87b5a1040521e1e24e9 ]
-
-Add struct backtrack_state and straightforward API around it to keep
-track of register and stack masks used and maintained during precision
-backtracking process. Having this logic separately allow to keep
-high-level backtracking algorithm cleaner, but also it sets us up to
-cleanly keep track of register and stack masks per frame, allowing (with
-some further logic adjustments) to perform precision backpropagation
-across multiple frames (i.e., subprog calls).

-Subject: bpf: Factor out socket lookup functions for the TC hookpoint.
-
-From: Gilad Sever <gilad9366@gmail.com>
-
-[ Upstream commit 6e98730bc0b44acaf86eccc75f823128aa9c9e79 ]
-
-Change BPF helper socket lookup functions to use TC specific variants:
-bpf_tc_sk_lookup_tcp() / bpf_tc_sk_lookup_udp() / bpf_tc_skc_lookup_tcp()
-instead of sharing implementation with the cg / sk_skb hooking points.
-This allows introducing a separate logic for the TC flow.
-
-The tc functions are identical to the original code.

-Subject: bpf: Fix __bpf_{list,rbtree}_add's beginning-of-node calculation
-
-From: Dave Marchevsky <davemarchevsky@fb.com>
-
-[ Upstream commit cc0d76cafebbd3e1ffab9c4252d48ecc9e0737f6 ]
-
-Given the pointer to struct bpf_{rb,list}_node within a local kptr and
-the byte offset of that field within the kptr struct, the calculation changed
-by this patch is meant to find the beginning of the kptr so that it can
-be passed to bpf_obj_drop.
-
-Unfortunately instead of doing
-
- ptr_to_kptr = ptr_to_node_field - offset_bytes
-
-the calculation is erroneously doing
-
- ptr_to_ktpr = ptr_to_node_field - (offset_bytes * sizeof(struct bpf_rb_node))
-
-or the bpf_list_node equivalent.
-
-This patch fixes the calculation.

-Subject: bpf: Fix bpf socket lookup from tc/xdp to respect socket VRF bindings
-
-From: Gilad Sever <gilad9366@gmail.com>
-
-[ Upstream commit 9a5cb79762e0eda17ca15c2a6eaca4622383c21c ]
-
-When calling bpf_sk_lookup_tcp(), bpf_sk_lookup_udp() or
-bpf_skc_lookup_tcp() from tc/xdp ingress, VRF socket bindings aren't
-respoected, i.e. unbound sockets are returned, and bound sockets aren't
-found.
-
-VRF binding is determined by the sdif argument to sk_lookup(), however
-when called from tc the IP SKB control block isn't initialized and thus
-inet{,6}_sdif() always returns 0.
-
-Fix by calculating sdif for the tc/xdp flows by observing the device's
-l3 enslaved state.
-
-The cg/sk_skb hooking points which are expected to support
-inet{,6}_sdif() pass sdif=-1 which makes __bpf_skc_lookup() use the
-existing logic.

-Subject: bpf: Fix memleak due to fentry attach failure
-
-From: Yafang Shao <laoar.shao@gmail.com>
-
-[ Upstream commit 108598c39eefbedc9882273ac0df96127a629220 ]
-
-If it fails to attach fentry, the allocated bpf trampoline image will be
-left in the system. That can be verified by checking /proc/kallsyms.
-
-This meamleak can be verified by a simple bpf program as follows:
-
- SEC("fentry/trap_init")
- int fentry_run()
- {
- return 0;
- }
-
-It will fail to attach trap_init because this function is freed after
-kernel init, and then we can find the trampoline image is left in the
-system by checking /proc/kallsyms.
-
- $ tail /proc/kallsyms
- ffffffffc0613000 t bpf_trampoline_6442453466_1 [bpf]
- ffffffffc06c3000 t bpf_trampoline_6442453466_1 [bpf]
-
- $ bpftool btf dump file /sys/kernel/btf/vmlinux | grep "FUNC 'trap_init'"
- [2522] FUNC 'trap_init' type_id=119 linkage=static
-
- $ echo $((6442453466 & 0x7fffffff))
- 2522
-
-Note that there are two left bpf trampoline images, that is because the
-libbpf will fallback to raw tracepoint if -EINVAL is returned.

-Subject: bpf: fix propagate_precision() logic for inner frames
-
-From: Andrii Nakryiko <andrii@kernel.org>
-
-[ Upstream commit f655badf2a8fc028433d9583bf86a6b473721f09 ]
-
-Fix propagate_precision() logic to perform propagation of all necessary
-registers and stack slots across all active frames *in one batch step*.
-
-Doing this for each register/slot in each individual frame is wasteful,
-but the main problem is that backtracking of instruction in any frame
-except the deepest one just doesn't work. This is due to backtracking
-logic relying on jump history, and available jump history always starts
-(or ends, depending how you view it) in current frame. So, if
-prog A (frame #0) called subprog B (frame #1) and we need to propagate
-precision of, say, register R6 (callee-saved) within frame #0, we
-actually don't even know where jump history that corresponds to prog
-A even starts. We'd need to skip subprog part of jump history first to
-be able to do this.
-
-Luckily, with struct backtrack_state and __mark_chain_precision()
-handling bitmasks tracking/propagation across all active frames at the
-same time (added in previous patch), propagate_precision() can be both
-fixed and sped up by setting all the necessary bits across all frames
-and then performing one __mark_chain_precision() pass. This makes it
-unnecessary to skip subprog parts of jump history.
-
-We also improve logging along the way, to clearly specify which
-registers' and slots' precision markings are propagated within which
-frame. Each frame will have dedicated line and all registers and stack
-slots from that frame will be reported in format similar to precision
-backtrack regs/stack logging. E.g.:
-
-frame 1: propagating r1,r2,r3,fp-8,fp-16
-frame 0: propagating r3,r9,fp-120
-
-Fixes: 529409ea92d5 ("bpf: propagate precision across all frames, not just the last one")

-
-[ Upstream commit d9439c21a9e4769bfd83a03ab39056164d44ac31 ]
-
-Add helper to format register and stack masks in more human-readable
-format. Adjust logging a bit during backtrack propagation and especially
-during forcing precision fallback logic to make it clearer what's going
-on (with log_level=2, of course), and also start reporting affected
-frame depth. This is in preparation for having more than one active
-frame later when precision propagation between subprog calls is added.

-Subject: bpf: maintain bitmasks across all active frames in
- __mark_chain_precision
-
-From: Andrii Nakryiko <andrii@kernel.org>
-
-[ Upstream commit 1ef22b6865a73a8aed36d43375fe8c7b30869326 ]
-
-Teach __mark_chain_precision logic to maintain register/stack masks
-across all active frames when going from child state to parent state.
-Currently this should be mostly no-op, as precision backtracking usually
-bails out when encountering subprog entry/exit.
-
-It's not very apparent from the diff due to increased indentation, but
-the logic remains the same, except everything is done on specific `fr`
-frame index. Calls to bt_clear_reg() and bt_clear_slot() are replaced
-with frame-specific bt_clear_frame_reg() and bt_clear_frame_slot(),
-where frame index is passed explicitly, instead of using current frame
-number.
-
-We also adjust logging to emit affected frame number. And we also add
-better logging of human-readable register and stack slot masks, similar
-to previous patch.

-Subject: bpf: Make bpf_refcount_acquire fallible for non-owning refs
-
-From: Dave Marchevsky <davemarchevsky@fb.com>
-
-[ Upstream commit 7793fc3babe9fea908e57f7c187ea819f9fd7e95 ]
-
-This patch fixes an incorrect assumption made in the original
-bpf_refcount series [0], specifically that the BPF program calling
-bpf_refcount_acquire on some node can always guarantee that the node is
-alive. In that series, the patch adding failure behavior to rbtree_add
-and list_push_{front, back} breaks this assumption for non-owning
-references.
-
-Consider the following program:
-
- n = bpf_kptr_xchg(&mapval, NULL);
- /* skip error checking */
-
- bpf_spin_lock(&l);
- if(bpf_rbtree_add(&t, &n->rb, less)) {
- bpf_refcount_acquire(n);
- /* Failed to add, do something else with the node */
- }
- bpf_spin_unlock(&l);
-
-It's incorrect to assume that bpf_refcount_acquire will always succeed in this
-scenario. bpf_refcount_acquire is being called in a critical section
-here, but the lock being held is associated with rbtree t, which isn't
-necessarily the lock associated with the tree that the node is already
-in. So after bpf_rbtree_add fails to add the node and calls bpf_obj_drop
-in it, the program has no ownership of the node's lifetime. Therefore
-the node's refcount can be decr'd to 0 at any time after the failing
-rbtree_add. If this happens before the refcount_acquire above, the node
-might be free'd, and regardless refcount_acquire will be incrementing a
-0 refcount.
-
-Later patches in the series exercise this scenario, resulting in the
-expected complaint from the kernel (without this patch's changes):
-
- refcount_t: addition on 0; use-after-free.

- Call Trace:
- <TASK>
- bpf_refcount_acquire_impl+0xb5/0xc0
-
- (rest of output snipped)
-
-The patch addresses this by changing bpf_refcount_acquire_impl to use
-refcount_inc_not_zero instead of refcount_inc and marking
-bpf_refcount_acquire KF_RET_NULL.
-
-For owning references, though, we know the above scenario is not possible
-and thus that bpf_refcount_acquire will always succeed. Some verifier
-bookkeeping is added to track "is input owning ref?" for bpf_refcount_acquire
-calls and return false from is_kfunc_ret_null for bpf_refcount_acquire on
-owning refs despite it being marked KF_RET_NULL.
-
-Existing selftests using bpf_refcount_acquire are modified where
-necessary to NULL-check its return value.

-Subject: bpf: Remove anonymous union in bpf_kfunc_call_arg_meta
-
-From: Dave Marchevsky <davemarchevsky@fb.com>
-
-[ Upstream commit 4d585f48ee6b38c54c075b151c5efd2ff65f8ffd ]
-
-For kfuncs like bpf_obj_drop and bpf_refcount_acquire - which take
-user-defined types as input - the verifier needs to track the specific
-type passed in when checking a particular kfunc call. This requires
-tracking (btf, btf_id) tuple. In commit 7c50b1cb76ac
-("bpf: Add bpf_refcount_acquire kfunc") I added an anonymous union with
-inner structs named after the specific kfuncs tracking this information,
-with the goal of making it more obvious which kfunc this data was being
-tracked / expected to be tracked on behalf of.
-
-In a recent series adding a new user of this tuple, Alexei mentioned
-that he didn't like this union usage as it doesn't really help with
-readability or bug-proofing ([0]). In an offline convo we agreed to
-have the tuple be fields (arg_btf, arg_btf_id), with comments in
-bpf_kfunc_call_arg_meta definition enumerating the uses of the fields by
-kfunc-specific handling logic. Such a pattern is used by struct
-bpf_reg_state without trouble.
-
-Accordingly, this patch removes the anonymous union in favor of arg_btf
-and arg_btf_id fields and comment enumerating their current uses. The
-patch also removes struct btf_and_id, which was only being used by the
-removed union's inner structs.
-
-This is a mechanical change, existing linked_list and rbtree tests will
-validate that correct (btf, btf_id) are being passed.

-Subject: bpf: Remove bpf trampoline selector
-
-From: Yafang Shao <laoar.shao@gmail.com>
-
-[ Upstream commit 47e79cbeea4b3891ad476047f4c68543eb51c8e0 ]
-
-After commit e21aa341785c ("bpf: Fix fexit trampoline."), the selector is only
-used to indicate how many times the bpf trampoline image are updated and been
-displayed in the trampoline ksym name. After the trampoline is freed, the
-selector will start from 0 again. So the selector is a useless value to the
-user. We can remove it.
-
-If the user want to check whether the bpf trampoline image has been updated
-or not, the user can compare the address. Each time the trampoline image is
-updated, the address will change consequently. Jiri also pointed out another
-issue that perf is still using the old name "bpf_trampoline_%lu", so this
-change can fix the issue in perf.

-Subject: bpf: Set kptr_struct_meta for node param to list and rbtree insert
- funcs
-
-From: Dave Marchevsky <davemarchevsky@fb.com>
-
-[ Upstream commit 2140a6e3422de22e6ebe77d4d18b6c0c9c425426 ]
-
-In verifier.c, fixup_kfunc_call uses struct bpf_insn_aux_data's
-kptr_struct_meta field to pass information about local kptr types to
-various helpers and kfuncs at runtime. The recent bpf_refcount series
-added a few functions to the set that need this information:
-
- * bpf_refcount_acquire
- * Needs to know where the refcount field is in order to increment
- * Graph collection insert kfuncs: bpf_rbtree_add, bpf_list_push_{front,back}
- * Were migrated to possibly fail by the bpf_refcount series. If
- insert fails, the input node is bpf_obj_drop'd. bpf_obj_drop needs
- the kptr_struct_meta in order to decr refcount and properly free
- special fields.
-
-Unfortunately the verifier handling of collection insert kfuncs was not
-modified to actually populate kptr_struct_meta. Accordingly, when the
-node input to those kfuncs is passed to bpf_obj_drop, it is done so
-without the information necessary to decr refcount.
-
-This patch fixes the issue by populating kptr_struct_meta for those
-kfuncs.

-From: Eduard Zingerman <eddyz87@gmail.com>
-
-[ Upstream commit 904e6ddf4133c52fdb9654c2cd2ad90f320d48b9 ]
-
-Change mark_chain_precision() to track precision in situations
-like below:
-
- r2 = unknown value
- ...
- --- state #0 ---
- ...
- r1 = r2 // r1 and r2 now share the same ID
- ...
- --- state #1 {r1.id = A, r2.id = A} ---
- ...
- if (r2 > 10) goto exit; // find_equal_scalars() assigns range to r1
- ...
- --- state #2 {r1.id = A, r2.id = A} ---
- r3 = r10
- r3 += r1 // need to mark both r1 and r2
-
-At the beginning of the processing of each state, ensure that if a
-register with a scalar ID is marked as precise, all registers sharing
-this ID are also marked as precise.
-
-This property would be used by a follow-up change in regsafe().

-Subject: bpf: Verify scalar ids mapping in regsafe() using check_ids()
-
-From: Eduard Zingerman <eddyz87@gmail.com>
-
-[ Upstream commit 1ffc85d9298e0ca0137ba65c93a786143fe167b8 ]
-
-Make sure that the following unsafe example is rejected by verifier:
-
-1: r9 = ... some pointer with range X ...
-2: r6 = ... unbound scalar ID=a ...
-3: r7 = ... unbound scalar ID=b ...
-4: if (r6 > r7) goto +1
-5: r6 = r7
-6: if (r6 > X) goto ...
---- checkpoint ---
-7: r9 += r7
-8: *(u64 *)r9 = Y
-
-This example is unsafe because not all execution paths verify r7 range.
-Because of the jump at (4) the verifier would arrive at (6) in two states:
-I. r6{.id=b}, r7{.id=b} via path 1-6;
-II. r6{.id=a}, r7{.id=b} via path 1-4, 6.
-
-Currently regsafe() does not call check_ids() for scalar registers,
-thus from POV of regsafe() states (I) and (II) are identical. If the
-path 1-6 is taken by verifier first, and checkpoint is created at (6)
-the path [1-4, 6] would be considered safe.
-
-Changes in this commit:
-- check_ids() is modified to disallow mapping multiple old_id to the
- same cur_id.
-- check_scalar_ids() is added, unlike check_ids() it treats ID zero as
- a unique scalar ID.
-- check_scalar_ids() needs to generate temporary unique IDs, field
- 'tmp_id_gen' is added to bpf_verifier_env::idmap_scratch to
- facilitate this.
-- regsafe() is updated to:
- - use check_scalar_ids() for precise scalar registers.
- - compare scalar registers using memcmp only for explore_alu_limits
- branch. This simplifies control flow for scalar case, and has no
- measurable performance impact.
-- check_alu_op() is updated to avoid generating bpf_reg_state::id for
- constant scalar values when processing BPF_MOV. ID is needed to
- propagate range information for identical values, but there is
- nothing to propagate for constants.
-
-Fixes: 75748837b7e5 ("bpf: Propagate scalar ranges through register assignments.")

-
-From: Alan Maguire <alan.maguire@oracle.com>
-
-[ Upstream commit 04cb8453a91c7c22f60ddadb6cef0d19abb33bb5 ]
-
-On aarch64, "bpftool feature" reports an incorrect BPF JIT limit:
-
-$ sudo /sbin/bpftool feature
-Scanning system configuration...
-bpf() syscall restricted to privileged users
-JIT compiler is enabled
-JIT compiler hardening is disabled
-JIT compiler kallsyms exports are enabled for root
-skipping kernel config, can't open file: No such file or directory
-Global memory limit for JIT compiler for unprivileged users is -201326592 bytes
-
-This is because /proc/sys/net/core/bpf_jit_limit reports
-
-$ sudo cat /proc/sys/net/core/bpf_jit_limit
-68169519595520
-
-...and an int is assumed in read_procfs(). Change read_procfs()
-to return a long to avoid negative value reporting.

-Subject: btrfs: always read the entire extent_buffer
-
-From: Christoph Hellwig <hch@lst.de>
-
-[ Upstream commit e95382834cf885b478dbe14a66451b863eb35c94 ]
-
-Currently read_extent_buffer_pages skips pages that are already uptodate
-when reading in an extent_buffer. While this reduces the amount of data
-read, it increases the number of I/O operations as we now need to do
-multiple I/Os when reading an extent buffer with one or more uptodate
-pages in the middle of it. On any modern storage device, be that hard
-drives or SSDs this actually decreases I/O performance. Fortunately

-Subject: btrfs: don't fail writeback when allocating the compression context
- fails
-
-From: Christoph Hellwig <hch@lst.de>
-
-[ Upstream commit 973fb26e81a9f59dfe45b079a698c0e238f7bf69 ]
-
-If cow_file_range_async fails to allocate the asynchronous writeback
-context, it currently returns an error and entirely fails the writeback.
-This is not a good idea as a writeback failure is a non-temporary error
-condition that will make the file system unusable. Just fall back to
-synchronous uncompressed writeback instead. This requires us to delay
-setting the BTRFS_INODE_HAS_ASYNC_EXTENT flag until we've committed to
-the async writeback.
-
-The compression checks INODE_NOCOMPRESS and FORCE_COMPRESS are moved
-from cow_file_range_async to the preceding checks btrfs_run_delalloc_range().

-From: Christoph Hellwig <hch@lst.de>
-
-[ Upstream commit 7027f87108ce3d23ea542e1a9a79056530db4a87 ]
-
-When extent_write_locked_range was originally added, it was only used
-writing back compressed pages from an async helper thread. But it is
-now also used for writing back pages on zoned devices, where it is
-called directly from the ->writepage context. In this case we want to
-be able to pass on the writeback_control instead of creating a new one,
-and more importantly want to use all the normal cgroup interaction
-instead of potentially deferring writeback to another helper.

-[ Upstream commit b78b98e06fb7f9860da5a7c28e1edbaefc2f7be1 ]
-
-The btrfs_bio_ctrl machinery is overkill for reading extent_buffers
-as we always operate on PAGE_SIZE chunks (or one smaller one for the
-subpage case) that are contiguous and are guaranteed to fit into a
-single bio. Replace it with open coded btrfs_bio_alloc, __bio_add_page
-and btrfs_submit_bio calls in a helper function shared between
-the subpage and node size >= PAGE_SIZE cases.

-Subject: btrfs: fix file_offset for REQ_BTRFS_ONE_ORDERED bios that get split
-
-From: Christoph Hellwig <hch@lst.de>
-
-[ Upstream commit c731cd0b6d255e4855a7cac9f276864032ab2387 ]
-
-If a bio gets split, it needs to have a proper file_offset for checksum
-validation and repair to work properly.
-
-Based on feedback from Josef, commit 852eee62d31a ("btrfs: allow
-btrfs_submit_bio to split bios") skipped this adjustment for ONE_ORDERED
-bios. But if we actually ever need to split a ONE_ORDERED read bio, this
-will lead to a wrong file offset in the repair code. Right now the only
-user of the file_offset is logging of an error message so this is mostly
-harmless, but the wrong offset might be more problematic for additional
-users in the future.

-
-From: Christoph Hellwig <hch@lst.de>
-
-[ Upstream commit eb34dceace983e304e00d4bf711cec0a603959ac ]
-
-__extent_writepage does a lot of things that make no sense for
-extent_write_locked_range, given that extent_write_locked_range itself is
-called from __extent_writepage either directly or through a workqueue,
-and all this work has already been done in the first invocation and the
-pages haven't been unlocked since. Call __extent_writepage_io directly
-instead and open code the logic tracked in
-btrfs_bio_ctrl::extent_locked.

-Stop trying to cluster writes of multiple extent_buffers into a single
-bio. There is no need for that as the blk_plug mechanism used all the
-way up in writeback_inodes_wb gives us the same I/O pattern even with
-multiple bios. Removing the clustering simplifies

-Subject: can: length: fix bitstuffing count
-
-From: Vincent Mailhol <mailhol.vincent@wanadoo.fr>
-
-[ Upstream commit 9fde4c557f78ee2f3626e92b4089ce9d54a2573a ]
-
-The Stuff Bit Count is always coded on 4 bits [1]. Update the Stuff
-Bit Count size accordingly.
-
-In addition, the CRC fields of CAN FD Frames contain stuff bits at
-fixed positions called fixed stuff bits [2]. The CRC field starts with
-a fixed stuff bit and then has another fixed stuff bit after each
-fourth bit [2], which allows us to derive this formula:
-
- FSB count = 1 + round_down(len(CRC field)/4)
-
-The length of the CRC field is [1]:
-
- len(CRC field) = len(Stuff Bit Count) + len(CRC)
- = 4 + len(CRC)
-
-with len(CRC) either 17 or 21 bits depending of the payload length.
-
-In conclusion, for CRC17:
-
- FSB count = 1 + round_down((4 + 17)/4)
- = 6
-
-and for CRC 21:
-
- FSB count = 1 + round_down((4 + 21)/4)
- = 7
-
-Add a Fixed Stuff bits (FSB) field with above values and update
-CANFD_FRAME_OVERHEAD_SFF and CANFD_FRAME_OVERHEAD_EFF accordingly.
-
-[1] ISO 11898-1:2015 section 10.4.2.6 "CRC field":
-
- The CRC field shall contain the CRC sequence followed by a recessive
- CRC delimiter. For FD Frames, the CRC field shall also contain the
- stuff count.
-
- Stuff count
-
- If FD Frames, the stuff count shall be at the beginning of the CRC
- field. It shall consist of the stuff bit count modulo 8 in a 3-bit
- gray code followed by a parity bit [...]
-
-[2] ISO 11898-1:2015 paragraph 10.5 "Frame coding":
-
- In the CRC field of FD Frames, the stuff bits shall be inserted at
- fixed positions; they are called fixed stuff bits. There shall be a
- fixed stuff bit before the first bit of the stuff count, even if the
- last bits of the preceding field are a sequence of five consecutive
- bits of identical value, there shall be only the fixed stuff bit,
- there shall not be two consecutive stuff bits. A further fixed stuff
- bit shall be inserted after each fourth bit of the CRC field [...]

-Subject: cifs: do all necessary checks for credits within or before locking
-
-From: Shyam Prasad N <sprasad@microsoft.com>
-
-[ Upstream commit 326a8d04f147e2bf393f6f9cdb74126ee6900607 ]
-
-All the server credits and in-flight info is protected by req_lock.
-Once the req_lock is held, and we've determined that we have enough
-credits to continue, this lock cannot be dropped till we've made the
-changes to credits and in-flight count.
-
-However, we used to drop the lock in order to avoid deadlock with
-the recent srv_lock. This could cause the checks already made to be
-invalidated.
-
-Fixed it by moving the server status check to before locking req_lock.
-
-Fixes: d7d7a66aacd6 ("cifs: avoid use of global locks for high contention data")

-Subject: clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe()
-
-From: Yuxing Liu <lyx2022@hust.edu.cn>
-
-[ Upstream commit 878b02d5f3b56cb090dbe2c70c89273be144087f ]
-
-Replace of_iomap() and kzalloc() with devm_of_iomap() and devm_kzalloc()
-which can automatically release the related memory when the device
-or driver is removed or unloaded to avoid potential memory leak.
-
-In this case, iounmap(anatop_base) in line 427,433 are removed
-as manual release is not required.
-
-Besides, referring to clk-imx8mq.c, check the return code of
-of_clk_add_hw_provider, if it returns negtive, print error info
-and unregister hws, which makes the program more robust.

-Subject: clk: imx: composite-8m: Add imx8m_divider_determine_rate
-
-From: Adam Ford <aford173@gmail.com>
-
-[ Upstream commit 8208181fe536bba3b411508f81c4426fc9c71d9a ]
-
-Currently, certain clocks are derrived as a divider from their
-parent clock. For some clocks, even when CLK_SET_RATE_PARENT
-is set, the parent clock is not properly set which can lead
-to some relatively inaccurate clock values.
-
-Unlike imx/clk-composite-93 and imx/clk-divider-gate, it
-cannot rely on calling a standard determine_rate function,
-because the 8m composite clocks have a pre-divider and
-post-divider. Because of this, a custom determine_rate
-function is necessary to determine the maximum clock
-division which is equivalent to pre-divider * the
-post-divider.
-
-With this added, the system can attempt to adjust the parent rate
-when the proper flags are set which can lead to a more precise clock
-value.
-
-On the imx8mplus, no clock changes are present.
-On the Mini and Nano, this can help achieve more accurate
-lcdif clocks. When trying to get a pixel clock of 31.500MHz
-on an imx8m Nano, the clocks divided the 594MHz down, but
-left the parent rate untouched which caused a calulation error.
-
-Before:
-video_pll 594000000
- video_pll_bypass 594000000
- video_pll_out 594000000
- disp_pixel 31263158
- disp_pixel_clk 31263158
-
-Variance = -236842 Hz
-
-After this patch:
-video_pll 31500000
- video_pll_bypass 31500000
- video_pll_out 31500000
- disp_pixel 31500000
- disp_pixel_clk 31500000
-
-Variance = 0 Hz
-
-All other clocks rates and parent were the same.
-Similar results on imx8mm were found.

-Subject: clk: mediatek: clk-mtk: Grab iomem pointer for divider clocks
-
-From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
-
-[ Upstream commit 51821765e89906090753421580a61d25a4668186 ]
-
-In the rare case in which one of the clock drivers has divider clocks
-but not composite clocks, mtk_clk_simple_probe() would not io(re)map,
-hence passing a NULL pointer to mtk_clk_register_dividers().
-
-To fix this issue, extend the `if` conditional to also check if any
-divider clocks are present. While at it, also make sure the iomem
-pointer is NULL if no composite/divider clocks are declared, as we
-are checking for that when iounmapping it in the error path.
-
-This hasn't been seen on any MediaTek clock driver as the current ones
-always declare composite clocks along with divider clocks, but this is
-still an important fix for a future potential KP.

-This problem was also found in linux-next. In mtk_clk_simple_probe(),

-Subject: clk: si5341: return error if one synth clock registration fails
-
-From: Claudiu Beznea <claudiu.beznea@microchip.com>
-
-[ Upstream commit 2560114c06d7a752b3f4639f28cece58fed11267 ]
-
-In case devm_clk_hw_register() fails for one of synth clocks the probe
-continues. Later on, when registering output clocks which have as parents
-all the synth clocks, in case there is registration failure for at least
-one synth clock the information passed to clk core for registering output
-clock is not right: init.num_parents is fixed but init.parents may contain
-an array with less parents.

-Subject: cpufreq: intel_pstate: Fix energy_performance_preference for passive
-
-From: Tero Kristo <tero.kristo@linux.intel.com>
-
-[ Upstream commit 03f44ffb3d5be2fceda375d92c70ab6de4df7081 ]
-
-If the intel_pstate driver is set to passive mode, then writing the
-same value to the energy_performance_preference sysfs twice will fail.
-This is caused by the wrong return value used (index of the matched
-energy_perf_string), instead of the length of the passed in parameter.
-Fix by forcing the internal return value to zero when the same
-preference is passed in by user. This same issue is not present when
-active mode is used for the driver.

-Subject: crypto: jitter - correct health test during initialization
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Stephan Müller <smueller@chronox.de>
-
-[ Upstream commit d23659769ad1bf2cbafaa0efcbae20ef1a74f77e ]
-
-With the update of the permanent and intermittent health errors, the
-actual indicator for the health test indicates a potential error only
-for the one offending time stamp gathered in the current iteration
-round. The next iteration round will "overwrite" the health test result.
-
-Thus, the entropy collection loop in jent_gen_entropy checks for
-the health test failure upon each loop iteration. However, the
-initialization operation checked for the APT health test once for
-an APT window which implies it would not catch most errors.
-
-Thus, the check for all health errors is now invoked unconditionally
-during each loop iteration for the startup test.
-
-With the change, the error JENT_ERCT becomes unused as all health
-errors are only reported with the JENT_HEALTH return code. This
-allows the removal of the error indicator.
-
-Fixes: 3fde2fe99aa6 ("crypto: jitter - permanent and intermittent health errors"

-Subject: cxl/region: Flag partially torn down regions as unusable
-
-From: Dan Williams <dan.j.williams@intel.com>
-
-[ Upstream commit 2ab47045ac96a605e3037d479a7d5854570ee5bf ]
-
-cxl_region_decode_reset() walks all the decoders associated with a given
-region and disables them. Due to decoder ordering rules it is possible
-that a switch in the topology notices that a given decoder can not be
-shutdown before another region with a higher HPA is shutdown first. That
-can leave the region in a partially committed state.
-
-Capture that state in a new CXL_REGION_F_NEEDS_RESET flag and require
-that a successful cxl_region_decode_reset() attempt must be completed
-before cxl_region_probe() accepts the region.
-
-This is a corollary for the bug that Jonathan identified in "CXL/region
-: commit reset of out of order region appears to succeed." [1].

-Subject: cxl/region: Move cache invalidation before region teardown, and
- before setup
-
-From: Dan Williams <dan.j.williams@intel.com>
-
-[ Upstream commit d1257d098a5a38753a0736a50db0a26a62377ad7 ]
-
-Vikram raised a concern with the theoretical case of a CPU sending
-MemClnEvict to a device that is not prepared to receive. MemClnEvict is
-a message that is sent after a CPU has taken ownership of a cacheline
-from accelerator memory (HDM-DB). In the case of hotplug or HDM decoder
-reconfiguration it is possible that the CPU is holding old contents for
-a new device that has taken over the physical address range being cached
-by the CPU.
-
-To avoid this scenario, invalidate caches prior to tearing down an HDM
-decoder configuration.
-
-Now, this poses another problem that it is possible for something to
-speculate into that space while the decode configuration is still up, so
-to close that gap also invalidate prior to establish new contents behind
-a given physical address range.
-
-With this change the cache invalidation is now explicit and need not be
-checked in cxl_region_probe(), and that obviates the need for
-CXL_REGION_F_INCOHERENT.

-Subject: dax: Introduce alloc_dev_dax_id()
-
-From: Dan Williams <dan.j.williams@intel.com>
-
-[ Upstream commit 70aab281e18c68a1284bc387de127c2fc0bed3f8 ]
-
-The reference counting of dax_region objects is needlessly complicated,
-has lead to confusion [1], and has hidden a bug [2]. Towards cleaning up
-that mess introduce alloc_dev_dax_id() to minimize the holding of a
-dax_region reference to only what dev_dax_release() needs, the
-dax_region->ida.
-
-Part of the reason for the mess was the design to dereference a
-dax_region in all cases in free_dev_dax_id() even if the id was
-statically assigned by the upper level dax_region driver. Remove the
-need to call "is_static(dax_region)" by tracking whether the id is
-dynamic directly in the dev_dax instance itself.
-
-With that flag the dax_region pinning and release per dev_dax instance
-can move to alloc_dev_dax_id() and free_dev_dax_id() respectively.
-
-A follow-on cleanup address the unnecessary references in the dax_region
-setup and drivers.

-The hash_for_each_possible() loop dereferences "eve_data" to get the

-Subject: drivers/perf: apple_m1: Force 63bit counters for M2 CPUs
-
-From: Marc Zyngier <maz@kernel.org>
-
-[ Upstream commit 8be3593b9efa8903d2ee7bb9cdf57a8e56c66f36 ]
-
-Sidharth reports that on M2, the PMU never generates any interrupt
-when using 'perf record', which is a annoying as you get no sample.
-I'm temped to say "no sample, no problem", but others may have
-a different opinion.
-
-Upon investigation, it appears that the counters on M2 are
-significantly different from the ones on M1, as they count on
-64 bits instead of 48. Which of course, in the fine M1 tradition,
-means that we can only use 63 bits, as the top bit is used to signal
-the interrupt...
-
-This results in having to introduce yet another flag to indicate yet
-another odd counter width. Who knows what the next crazy implementation
-will do...
-
-With this, perf can work out the correct offset, and 'perf record'
-works as intended.
-
-Tested on M2 and M2-Pro CPUs.

-Subject: drm/amd/display: Explicitly specify update type per plane info change
-
-From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
-
-[ Upstream commit 710cc1e7cd461446a9325c9bd1e9a54daa462952 ]
-
-[Why]
-The bit for flip addr is being set causing the determination for
-FAST vs MEDIUM to always return MEDIUM when plane info is provided
-as a surface update. This causes extreme stuttering for the typical
-atomic update path on Linux.
-
-[How]
-Don't use update_flags->raw for determining FAST vs MEDIUM. It's too
-fragile to changes like this.
-
-Explicitly specify the update type per update flag instead. It's not
-as clever as checking the bits itself but at least it's correct.
-
-Fixes: aa5fdb1ab5b6 ("drm/amd/display: Explicitly specify update type per plane info change")

-Subject: drm/amd/display: Fix artifacting on eDP panels when engaging freesync
- video mode
-
-From: Aurabindo Pillai <aurabindo.pillai@amd.com>
-
-[ Upstream commit b18f05a0666aecd5cb19c26a8305bcfa4e9d6502 ]
-
-[Why]
-When freesync video mode is enabled, switching resolution from native
-mode to one of the freesync video compatible modes can trigger continous
-artifacts on some eDP panels when running under KDE. The articating can be seen in the
-attached bug report.
-
-[How]
-Fix this by restricting updates that require full commit by using the same checks
-for stream and scaling changes in the the enable pass of dm_update_crtc_state()
-along with the check for compatible timings for freesync vide mode.

-Subject: drm/amdgpu: Fix usage of UMC fill record in RAS
-
-From: Luben Tuikov <luben.tuikov@amd.com>
-
-[ Upstream commit 71344a718a9fda8c551cdc4381d354f9a9907f6f ]
-
-The fixed commit listed in the Fixes tag below, introduced a bug in
-amdgpu_ras.c::amdgpu_reserve_page_direct(), in that when introducing the new
-amdgpu_umc_fill_error_record() and internally in that new function the physical
-address (argument "uint64_t retired_page"--wrong name) is right-shifted by
-AMDGPU_GPU_PAGE_SHIFT. Thus, in amdgpu_reserve_page_direct() when we pass
-"address" to that new function, we should NOT right-shift it, since this
-results, erroneously, in the page address to be 0 for first
-2^(2*AMDGPU_GPU_PAGE_SHIFT) memory addresses.
-
-This commit fixes this bug.

-Subject: drm/bridge: anx7625: Prevent endless probe loop
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Nícolas F. R. A. Prado <nfraprado@collabora.com>
-
-[ Upstream commit 1464e48d69ab7a50a377c9d39f5e5eb3cee2722e ]
-
-During probe, the driver registers i2c dummy devices and populates the
-aux bus, which registers a device for the panel. After doing that, the
-driver can still defer probe if needed. This ordering of operations is
-troublesome however, because the deferred probe work will retry probing
-all pending devices every time a new device is registered. Therefore, if
-modules need to be loaded in order to satisfy the dependencies for this
-driver to complete probe, the kernel will stall, since it'll keep trying
-to probe the anx7625 driver, but never succeed, given that modules would
-only be loaded after the deferred probe work completes.
-
-Two changes are required to avoid this issue:
-* Move of_find_mipi_dsi_host_by_node(), which can defer probe, to before
- anx7625_register_i2c_dummy_clients() and
- devm_of_dp_aux_populate_ep_devices(), which register devices.
-* Make use of the done_probing callback when populating the aux bus,
- so that the bridge registration is only done after the panel is
- probed. This is required because the panel might need to defer probe,
- but the aux bus population needs the i2c dummy devices working, so
- this call couldn't just be moved to an earlier point in probe.
- One caveat is that if the panel is described outside the aux bus, the
- probe loop issue can still happen, but we don't have a way to avoid
- it in that case since there's no callback available.
-
-With this patch applied, it's possible to boot on
-mt8192-asurada-spherion with
-
-CONFIG_DRM_ANALOGIX_ANX7625=y
-CONFIG_MTK_MMSYS=m

-Subject: drm: bridge: samsung-dsim: Fix PMS Calculator on imx8m[mnp]
-
-From: Adam Ford <aford173@gmail.com>
-
-[ Upstream commit 54f1a83c72250b182fa7722b0c5f6eb5e769598d ]
-
-According to Table 13-45 of the i.MX8M Mini Reference Manual, the min
-and max values for M and the frequency range for the VCO_out
-calculator were incorrect. This information was contradicted in other
-parts of the mini, nano and plus manuals. After reaching out to my
-NXP Rep, when confronting him about discrepencies in the Nano manual,
-he responded with:
- "Yes it is definitely wrong, the one that is part
- of the NOTE in MIPI_DPHY_M_PLLPMS register table against PMS_P,
- PMS_M and PMS_S is not correct. I will report this to Doc team,
- the one customer should be take into account is the Table 13-40
- DPHY PLL Parameters and the Note above."
-
-These updated values also match what is used in the NXP downstream
-kernel.
-
-To fix this, make new variables to hold the min and max values of m
-and the minimum value of VCO_out, and update the PMS calculator to
-use these new variables instead of using hard-coded values to keep
-the backwards compatibility with other parts using this driver.

-
-[ Upstream commit cec5ccef85bd0128cf895612de54a9d21d2015d0 ]
-
-Add atomic_get_input_bus_fmts() implementation, tc358768 has a parallel
-RGB input interface with the actual bus format depending on the amount
-of parallel input data lines.
-
-Without this change when the tc358768 is used with less than 24bit the
-color mapping is completely wrong.

-Subject: drm/bridge: tc358768: always enable HS video mode
-
-From: Francesco Dolcini <francesco.dolcini@toradex.com>
-
-[ Upstream commit 75a8aeac2573ab258c53676eba9b3796ea691988 ]
-
-Always enable HS video mode setting the TXMD bit, without this change no
-video output is present with DSI sinks that are setting
-MIPI_DSI_MODE_LPM flag (tested with LT8912B DSI-HDMI bridge).
-
-Previously the driver was enabling HS mode only when the DSI sink was
-not explicitly setting the MIPI_DSI_MODE_LPM, however this is not
-correct.
-
-The MIPI_DSI_MODE_LPM is supposed to indicate that the sink is willing
-to receive data in low power mode, however clearing the
-TC358768_DSI_CONTROL_TXMD bit will make the TC358768 send video in
-LP mode that is not the intended behavior.

-
-[ Upstream commit ee18698e212b1659dd0850d7e2ae0f22e16ed3d3 ]
-
-Correct computation of TCLK_TRAILCNT register.
-
-The driver does not implement non-continuous clock mode, so the actual
-value doesn't make a practical difference yet. However this change also
-ensures that the value does not write to reserved registers bits in case
-of under/overflow.
-
-This register must be set to a value that ensures that
-
-TCLK-TRAIL > 60ns
- and
-TEOT <= (105 ns + 12 x UI)
-
-with the actual value of TCLK-TRAIL being
-
-(TCLK_TRAILCNT + (1 to 2)) xHSByteClkCycle +
- (2 + (1 to 2)) * HSBYTECLKCycle - (PHY output delay)
-
-with PHY output delay being about
-
-(2 to 3) x MIPIBitClk cycle in the BitClk conversion.

-Subject: drm/bridge: ti-sn65dsi83: Fix enable/disable flow to meet spec
-
-From: Frieder Schrempf <frieder.schrempf@kontron.de>
-
-[ Upstream commit dd9e329af7236e34c566d3705ea32a63069b9b13 ]
-
-The datasheet describes the following initialization flow including
-minimum delay times between each step:
-
-1. DSI data lanes need to be in LP-11 and the clock lane in HS mode
-2. toggle EN signal
-3. initialize registers
-4. enable PLL
-5. soft reset
-6. enable DSI stream
-7. check error status register
-
-To meet this requirement we need to make sure the host bridge's
-pre_enable() is called first by using the pre_enable_prev_first
-flag.
-
-Furthermore we need to split enable() into pre_enable() which covers
-steps 2-5 from above and enable() which covers step 7 and is called
-after the host bridge's enable().

-info structure, just provide a pointer to the display-specific
-structure. This is in preparation for moving the display device info
-definitions into the display code itself and for eventually allowing the
-pointer to be assigned at runtime on platforms that use GMD_ID for
-device identification.
-
-In the future, this will also eventually allow the same display device
-info structures to be used outside the current i915 code (e.g., from the
-Xe driver).
-
-v2:
- - Move introduction of DISPLAY_INFO() to this patch. (Andrzej)
-v3:
- - Also use DISPLAY_INFO() in intel_display_reg_defs.h. (Andrzej)
- - Use "{}" instead of "{ 0 }" for empty struct init. (Jani)

-Subject: drm/i915/display: Make display responsible for probing its own IP
-
-From: Matt Roper <matthew.d.roper@intel.com>
-
-[ Upstream commit 69d439818fe501e8c9e50d963a53cb596e36f9f7 ]
-
-Rather than selecting the display IP and feature flags at the same time
-the general PCI probing happens, move this step into the display code
-itself so that it can be more easily re-used outside of i915 (i.e., by
-the Xe driver).
-
-v2:
- - Make intel_display_device_probe() always return a non-NULL pointer
- and simplify copying of runtime_defaults. (Andrzej)
-v3:
- - Redefine INTEL_VGA_DEVICE/INTEL_QUANTA_DEVICE to eliminate a cast and
- an include of linux/mod_devicetable.h. (Jani)
- - Keep explicit memcpy for runtime defaults. (Jani)

-
-Moving display-specific substructure definitions will help keep display
-more self-contained and make it easier to re-use in other drivers (i.e.,
-Xe) in the future.

-Subject: drm/i915/display: Move display runtime info to display structure
-
-From: Matt Roper <matthew.d.roper@intel.com>
-
-[ Upstream commit 18e0deeed8c80d8ec0adfff3312252028739ce52 ]
-
-Move the runtime info specific to display into display-specific
-structures as has already been done with the constant display info.
-
-v2:
- - Rename __runtime to __runtime_defaults for more clarity on the
- purpose. (Andrzej)
- - Move introduction of DISPLAY_INFO() to previous patch. (Andrzej)
- - Drop NO_DISPLAY macro. (Andrzej)
-v3:
- - Use "{}" instead of "{ 0 }" for empty struct init. (Jani)

-Subject: drm/i915: Fix limited range csc matrix
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Ville Syrjälä <ville.syrjala@linux.intel.com>
-
-[ Upstream commit 404c3acda4b65924c05bc63242e94f954f84c165 ]
-
-Our current limited range matrix is a bit off. I think it
-was originally calculated with rounding, as if we wanted
-the normal pixel replication type of behaviour.
-That is, since the 8bpc max value is 0xeb we assumed the
-16bpc max value should be 0xebeb, but what the HDMI spec
-actually says it should be is 0xeb00.
-
-So to get what we want we make the formula
- out = in * (235-16) << (12-8) / in_max + 16 << (12-8),
-with 12 being precision of the csc, 8 being the precision
-of the constants we used.
-
-The hardware takes its coefficients as floating point
-values, but the (235−16)/255 = ~.86, so exponent 0
-is what we want anyway, so it works out perfectly without
-having to hardcode it in hex or start playing with floats.
-
-In terms of raw numbers we are feeding the hardware the
-post offset changes from 0x101 to 0x100, and the coefficient
-changes from 0xdc0 to 0xdb0 (~.860->~.855). So this should
-make everything come out just a tad darker.
-
-I already used better constants in lut_limited_range() earlier
-so the output of the two paths should be closer now.

-Subject: drm/i915/guc/slpc: Provide sysfs for efficient freq
-
-From: Vinay Belgaumkar <vinay.belgaumkar@intel.com>
-
-[ Upstream commit 55f9720dbf23ed640a51ea5564c22305efa8a467 ]
-
-SLPC enables use of efficient freq at init by default. It is
-possible for GuC to request frequencies that are higher than
-the 'software' max if user has set it lower than the efficient
-level.
-
-Scenarios/tests that require strict fixing of freq below the efficient
-level will need to disable it through this interface.
-
-v2: Keep just one interface to toggle sysfs. With this, user will
-be completely responsible for toggling efficient frequency if need
-be. There will be no implicit disabling when user sets min < RP1 (Ashutosh)
-
-v3: Remove unused label, review comments (Ashutosh)
-
-v4: Toggle efficient freq usage in SLPC selftest and checkpatch fixes
-
-v5: Review comments (Andi) and add a separate patch for selftest updates
-
-Fixes: 95ccf312a1e4 ("drm/i915/guc/slpc: Allow SLPC to use efficient frequency")

-Subject: drm/i915: hide mkwrite_device_info() better
-
-From: Jani Nikula <jani.nikula@intel.com>
-
-[ Upstream commit 446a20c9ba622bb531f1705eab88b64d478ee434 ]
-
-The goal has been to just make device info a pointer to static const
-data, i.e. the static const structs in i915_pci.c. See [1]. However,
-there were issues with intel_device_info_runtime_init() clearing the
-display sub-struct of device info on the !HAS_DISPLAY() path, which
-consequently disables a lot of display functionality, like it
-should. Looks like we'd have to cover all those paths, and maybe
-sprinkle HAS_DISPLAY() checks in them, which we haven't gotten around
-to.
-
-In the mean time, hide mkwrite_device_info() better within
-intel_device_info.c by adding a intel_device_info_driver_create() for
-the very early initialization of the device info and initial runtime
-info. This also lets us declutter i915_drv.h a bit, and stops promoting
-mkwrite_device_info() as something that could be used.

-[ Upstream commit 19db2062094c75c64039d820c2547aad4dcfd905 ]
-
-Apparently desktop gen3 parts don't support the
-10bit gamma mode at all. Stop claiming otherwise.
-
-As is the case with pipe A on gen3 mobile parts, the
-PIPECONF gamma mode bit can be set but it has no
-effect on the output.
-
-PNV seems to be the only slight exception, but generally
-the desktop PNV variant looks more like a mobile part so
-this is not entirely surprising.

-The commit 010c8bbad2cb ("drm: msm: adreno: Disable preemption on Adreno
-510") added special handling for a510 (this SKU doesn't seem to support
-preemption, so the driver should clamp nr_rings to 1). However the

-Subject: drm/msm/dp: Drop aux devices together with DP controller
-
-From: Bjorn Andersson <quic_bjorande@quicinc.com>
-
-[ Upstream commit a7bfb2ad2184a1fba78be35209b6019aa8cc8d4d ]
-
-Using devres to depopulate the aux bus made sure that upon a probe
-deferral the EDP panel device would be destroyed and recreated upon next
-attempt.
-
-But the struct device which the devres is tied to is the DPUs
-(drm_dev->dev), which may be happen after the DP controller is torn
-down.
-
-Indications of this can be seen in the commonly seen EDID-hexdump full
-of zeros in the log, or the occasional/rare KASAN fault where the
-panel's attempt to read the EDID information causes a use after free on
-DP resources.
-
-It's tempting to move the devres to the DP controller's struct device,
-but the resources used by the device(s) on the aux bus are explicitly
-torn down in the error path. The KASAN-reported use-after-free also
-remains, as the DP aux "module" explicitly frees its devres-allocated
-memory in this code path.
-
-As such, explicitly depopulate the aux bus in the error path, and in the
-component unbind path, to avoid these issues.

-
-There are two tiers of pending flush control, top level and
-individual hardware block. Currently only the top level of
-flush mask is reset to 0 but the individual pending flush masks
-of particular hardware blocks are left at their previous values,
-eventually accumulating all possible bit values and typically

-Reset all individual hardware block flush masks to 0 to avoid

-Subject: drm/msm/dpu: Disable pingpong TE on DPU 5.0.0 and above
-
-From: Marijn Suijten <marijn.suijten@somainline.org>
-
-[ Upstream commit fe9d66cf6e8d2f6651e55ae57026464a080c2f2a ]
-
-Since hardware revision 5.0.0 the TE configuration moved out of the
-PINGPONG block into the INTF block. Writing these registers has no
-effect, and is omitted downstream via the DPU/SDE_PINGPONG_TE feature
-flag. This flag is only added to PINGPONG blocks used by hardware prior
-to 5.0.0.
-
-The existing PP_BLK_TE macro has been removed in favour of directly
-passing this feature flag, which has thus far been the only difference
-with PP_BLK. PP_BLK_DITHER has been left in place as its embedded
-feature flag already excludes this DPU_PINGPONG_TE bit and differs by
-setting the block length to zero, as it only contains a DITHER subblock.
-
-The code that writes to these registers in the INTF block will follow in
-subsequent patches.

-Subject: drm/msm/dpu: Move autorefresh disable from CMD encoder to pingpong
-
-From: Marijn Suijten <marijn.suijten@somainline.org>
-
-[ Upstream commit 4a7c38ec7d8efe96c4d8b4d5fc0efb5b06db58e9 ]
-
-This autorefresh disable logic in the physical command-mode encoder
-consumes three callbacks to the pingpong block, and will explode in
-unnecessary complexity when the same callbacks need to be called on the
-interface block instead to accommodate INTF TE support. To clean this
-up, move the logic into the pingpong block under a disable_autorefresh
-callback, replacing the aforementioned three get_autorefresh,
-setup_autorefresh and get_vsync_info callbacks.
-
-The same logic will have to be replicated to the interface block when it
-receives INTF TE support, but it is less complex than constantly
-switching on a "has_intf_te" boolean to choose a callback.

-Subject: drm/msm/dpu: set DSC flush bit correctly at MDP CTL flush register
-
-From: Kuogee Hsieh <quic_khsieh@quicinc.com>
-
-[ Upstream commit 12cef323c903bd8b13d1f6ff24a9695c2cdc360b ]
-
-The CTL_FLUSH register should be programmed with the 22th bit
-(DSC_IDX) to flush the DSC hardware blocks, not the literal value of
-22 (which corresponds to flushing VIG1, VIG2 and RGB1 instead).
-
-Changes in V12:
--- split this patch out of "separate DSC flush update out of interface"
-
-Changes in V13:
--- rewording the commit text
-
-Changes in V14:
--- drop 'DSC" from "The DSC CTL_FLUSH register" at commit text

-
-From: Marijn Suijten <marijn.suijten@somainline.org>
-
-[ Upstream commit 853b292b92d50d1b30628c92229e93d670304e51 ]
-
-According to various downstream sources the PCC sub-block inside DSPP is
-version 4.0 since DPU 4.0 and higher, including SC7[12]80 at DPU version
-6.2 and 7.2 respectively. After correcting the version this struct
-becomes identical to sm8150_dspp_sblk which is used all across the
-catalog: replace uses of sc7180_dspp_sblk with that and remove
-the struct definition for sc7180_dspp_sblk entirely.

-Subject: drm/msm/dsi: don't allow enabling 14nm VCO with unprogrammed rate
-
-From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
-
-[ Upstream commit 1e0a97f84d73ea1182740f62069690c7f3271abb ]
-
-If the dispcc uses CLK_OPS_PARENT_ENABLE (e.g. on QCM2290), CCF can try
-enabling VCO before the rate has been programmed. This can cause clock
-lockups and/or other boot issues. Program the VCO to the minimal PLL
-rate if the read rate is 0 Hz.

-Subject: drm/msm/dsi: Remove incorrect references to slice_count
-
-From: Jessica Zhang <quic_jesszhan@quicinc.com>
-
-[ Upstream commit 155fa3a91d64221eb0885fd221cc8085dbef908f ]
-
-Currently, slice_count is being used to calculate word count and
-pkt_per_line. Instead, these values should be calculated using slice per
-packet, which is not the same as slice_count.
-
-Slice count represents the number of slices per interface, and its value
-will not always match that of slice per packet. For example, it is possible
-to have cases where there are multiple slices per interface but the panel
-specifies only one slice per packet.
-
-Thus, use the default value of one slice per packet and remove slice_count
-from the aforementioned calculations.
-
-Fixes: 08802f515c3c ("drm/msm/dsi: Add support for DSC configuration")
-Fixes: bc6b6ff8135c ("drm/msm/dsi: Use DSC slice(s) packet size to compute word count")

-
-[ Upstream commit 1becc57cd1a905e2aa0e1eca60d2a37744525c4a ]
-
-Function rv740_get_decoded_reference_divider() may return 0 due to
-unpredictable reference divider value calculated in
-radeon_atom_get_clock_dividers(). This will lead to
-division-by-zero error once that value is used as a divider
-in calculating 'clk_s'.
-While unlikely, this issue should nonetheless be prevented so add a
-sanity check for such cases by testing 'decoded_ref' value against 0.
-
-Found by Linux Verification Center (linuxtesting.org) with static
-analysis tool SVACE.

-v2: minor coding style fixes (Alex)
-In practice this should actually happen as the vbios should be
-properly populated.

-
-From: XuDong Liu <m202071377@hust.edu.cn>
-

-
-Smatch reports:
-drivers/gpu/drm/sun4i/sun4i_tcon.c:805 sun4i_tcon_init_clocks() warn:
-'tcon->clk' from clk_prepare_enable() not released on lines: 792,801.
-
-In the function sun4i_tcon_init_clocks(), tcon->clk and tcon->sclk0 are
-not disabled in the error handling, which affects the release of
-these variable. Although sun4i_tcon_bind(), which calls
-sun4i_tcon_init_clocks(), use sun4i_tcon_free_clocks to disable the
-variables mentioned, but the error handling branch of
-sun4i_tcon_init_clocks() ignores the required disable process.
-
-To fix this issue, use the devm_clk_get_enabled to automatically
-balance enable and disabled calls. As original implementation use
-sun4i_tcon_free_clocks() to disable clk explicitly, we delete the
-related calls and error handling that are no longer needed.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Maíra Canal <mcanal@igalia.com>
-
-[ Upstream commit ab87f558dcfb2562c3497e89600dec798a446665 ]
-
-Currently, the pixel conversion isn't rounding the fixed-point values
-before assigning it to the RGB coefficients, which is causing the IGT
-pixel-format tests to fail. So, use the drm_fixp2int_round() fixed-point
-helper to round the values when assigning it to the RGB coefficients.
-
-Tested with igt@kms_plane@pixel-format and igt@kms_plane@pixel-format-source-clamping.
-
-[v2]:
- * Use drm_fixp2int_round() to fix the pixel conversion instead of
- casting the values to s32 (Melissa Wen).

-Subject: efi/libstub: Disable PCI DMA before grabbing the EFI memory map
-
-From: Ard Biesheuvel <ardb@kernel.org>
-
-[ Upstream commit 2e28a798c3092ea42b968fa16ac835969d124898 ]
-
-Currently, the EFI stub will disable PCI DMA as the very last thing it
-does before calling ExitBootServices(), to avoid interfering with the
-firmware's normal operation as much as possible.
-
-However, the stub will invoke DisconnectController() on all endpoints
-downstream of the PCI bridges it disables, and this may affect the
-layout of the EFI memory map, making it substantially more likely that
-ExitBootServices() will fail the first time around, and that the EFI
-memory map needs to be reloaded.
-
-This, in turn, increases the likelihood that the slack space we
-allocated is insufficient (and we can no longer allocate memory via boot
-services after having called ExitBootServices() once), causing the
-second call to GetMemoryMap (and therefore the boot) to fail. This makes
-the PCI DMA disable feature a bit more fragile than it already is, so
-let's make it more robust, by allocating the space for the EFI memory
-map after disabling PCI DMA.
-
-Fixes: 4444f8541dad16fe ("efi: Allow disabling PCI busmastering on bridges during boot")

-Subject: erofs: fix compact 4B support for 16k block size
-
-From: Gao Xiang <hsiangkao@linux.alibaba.com>
-
-[ Upstream commit 001b8ccd0650727e54ec16ef72bf1b8eeab7168e ]
-
-In compact 4B, two adjacent lclusters are packed together as a unit to
-form on-disk indexes for effective random access, as below:
-
-(amortized = 4, vcnt = 2)
- _____________________________________________
- |___@_____ encoded bits __________|_ blkaddr _|
- 0 . amortized * vcnt = 8
- . .
- . . amortized * vcnt - 4 = 4
- . .
- .____________________________.
- |_type (2 bits)_|_clusterofs_|
-
-Therefore, encoded bits for each pack are 32 bits (4 bytes). IOWs,
-since each lcluster can get 16 bits for its type and clusterofs, the
-maximum supported lclustersize for compact 4B format is 16k (14 bits).
-
-Fix this to enable compact 4B format for 16k lclusters (blocks), which
-is tested on an arm64 server with 16k page size.

-Subject: erofs: kill hooked chains to avoid loops on deduplicated compressed
- images
-
-From: Gao Xiang <hsiangkao@linux.alibaba.com>
-
-[ Upstream commit 967c28b23f6c89bb8eef6a046ea88afe0d7c1029 ]
-
-After heavily stressing EROFS with several images which include a
-hand-crafted image of repeated patterns for more than 46 days, I found
-two chains could be linked with each other almost simultaneously and
-form a loop so that the entire loop won't be submitted. As a
-consequence, the corresponding file pages will remain locked forever.
-
-It can be _only_ observed on data-deduplicated compressed images.
-For example, consider two chains with five pclusters in total:
- Chain 1: 2->3->4->5 -- The tail pcluster is 5;
- Chain 2: 5->1->2 -- The tail pcluster is 2.
-
-Chain 2 could link to Chain 1 with pcluster 5; and Chain 1 could link
-to Chain 2 at the same time with pcluster 2.
-
-Since hooked chains are all linked locklessly now, I have no idea how
-to simply avoid the race. Instead, let's avoid hooked chains completely
-until I could work out a proper way to fix this and end users finally
-tell us that it's needed to add it back.
-
-Actually, this optimization can be found with multi-threaded workloads
-(especially even more often on deduplicated compressed images), yet I'm
-not sure about the overall system impacts of not having this compared
-with implementation complexity.

-From: Eric Biggers <ebiggers@google.com>
-
-[ Upstream commit d1f0c5ea04cd0a93309de0246278f0b22394692d ]
-
-bio_first_page_all(bio)->mapping->host is not compatible with large
-folios, since the first page of the bio is not necessarily the head page
-of the folio, and therefore it might not have the mapping pointer set.
-
-Therefore, move the dereference of ->mapping->host into
-verify_data_blocks(), which works with a folio.
-
-(Like the commit that this Fixes, this hasn't actually been tested with
-large folios yet, since the filesystems that use fs/verity/ don't
-support that yet. But based on code review, I think this is needed.)

-Subject: fsverity: use shash API instead of ahash API
-
-From: Eric Biggers <ebiggers@google.com>
-
-[ Upstream commit 8fcd94add6c5c93ed3b9314456e8420914401530 ]
-
-The "ahash" API, like the other scatterlist-based crypto APIs such as
-"skcipher", comes with some well-known limitations. First, it can't
-easily be used with vmalloc addresses. Second, the request struct can't
-be allocated on the stack. This adds complexity and a possible failure
-point that needs to be worked around, e.g. using a mempool.
-
-The only benefit of ahash over "shash" is that ahash is needed to access
-traditional memory-to-memory crypto accelerators, i.e. drivers/crypto/.
-However, this style of crypto acceleration has largely fallen out of
-favor and been superseded by CPU-based acceleration or inline crypto
-engines. Also, ahash needs to be used asynchronously to take full
-advantage of such hardware, but fs/verity/ has never done this.
-
-On all systems that aren't actually using one of these ahash-only crypto
-accelerators, ahash just adds unnecessary overhead as it sits between
-the user and the underlying shash algorithms.
-
-Also, XFS is planned to cache fsverity Merkle tree blocks in the
-existing XFS buffer cache. As a result, it will be possible for a
-single Merkle tree block to be split across discontiguous pages
-(https://lore.kernel.org/r/20230405233753.GU3223426@dread.disaster.area).
-This data will need to be hashed. It is easiest to work with a vmapped
-address in this case. However, ahash is incompatible with this.
-
-Therefore, let's convert fs/verity/ from ahash to shash. This
-simplifies the code, and it should also slightly improve performance for
-everyone who wasn't actually using one of these ahash-only crypto
-accelerators, i.e. almost everyone (or maybe even everyone)!

-Subject: gtp: Fix use-after-free in __gtp_encap_destroy().
-
-From: Kuniyuki Iwashima <kuniyu@amazon.com>
-
-[ Upstream commit ce3aee7114c575fab32a5e9e939d4bbb3dcca79f ]
-
-syzkaller reported use-after-free in __gtp_encap_destroy(). [0]
-
-It shows the same process freed sk and touched it illegally.
-
-Commit e198987e7dd7 ("gtp: fix suspicious RCU usage") added lock_sock()
-and release_sock() in __gtp_encap_destroy() to protect sk->sk_user_data,
-but release_sock() is called after sock_put() releases the last refcnt.

-Subject: hwmon: (f71882fg) prevent possible division by zero
-
-From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
-
-[ Upstream commit 0babf89c9cca7e074d6e59893e462e4886f481cc ]
-
-In the unlikely event that something goes wrong with the device and
-its registers, the fan_from_reg() function may return 0. This value
-will cause a division-by-zero error in the show_pwm() function.
-
-To prevent this, test the value of
-fan_from_reg(data->fan_full_speed[nr]) against 0 before performing
-the division. If the division-by-zero error is avoided, assign 0 to
-the val variable.

-Found by Linux Verification Center (linuxtesting.org) with static
-analysis tool SVACE.

-Subject: hwmon: (pmbus/adm1275) Fix problems with temperature monitoring on
- ADM1272
-
-From: Guenter Roeck <linux@roeck-us.net>
-
-[ Upstream commit b153a0bb4199566abd337119207f82b59a8cd1ca ]
-
-The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit
-value into it clears the upper 8 bits of the register, resulting in
-unexpected side effects. Fix by writing the 16 bit register value.
-
-Also, it has been reported that temperature readings are sometimes widely
-inaccurate, to the point where readings may result in device shutdown due
-to errant overtemperature faults. Improve by enabling temperature sampling.
-
-While at it, move the common code for ADM1272 and ADM1278 into a separate
-function, and clarify in the error message that an attempt was made to
-enable both VOUT and temperature monitoring.
-
-Last but not least, return the error code reported by the underlying I2C
-controller and not -ENODEV if updating the PMON_CONFIG register fails.
-After all, this does not indicate that the chip is not present, but an
-error in the communication with the chip.

-Subject: hwrng: st - keep clock enabled while hwrng is registered
-
-From: Martin Kaiser <martin@kaiser.cx>
-
-[ Upstream commit 501e197a02d4aef157f53ba3a0b9049c3e52fedc ]
-
-The st-rng driver uses devres to register itself with the hwrng core,
-the driver will be unregistered from hwrng when its device goes out of
-scope. This happens after the driver's remove function is called.
-
-However, st-rng's clock is disabled in the remove function. There's a
-short timeframe where st-rng is still registered with the hwrng core
-although its clock is disabled. I suppose the clock must be active to
-access the hardware and serve requests from the hwrng core.
-
-Switch to devm_clk_get_enabled and let devres disable the clock and
-unregister the hwrng. This avoids the race condition.

-Subject: hwrng: virtio - Fix race on data_avail and actual data
-
-From: Herbert Xu <herbert@gondor.apana.org.au>
-
-[ Upstream commit ac52578d6e8d300dd50f790f29a24169b1edd26c ]
-
-The virtio rng device kicks off a new entropy request whenever the
-data available reaches zero. When a new request occurs at the end
-of a read operation, that is, when the result of that request is
-only needed by the next reader, then there is a race between the
-writing of the new data and the next reader.
-
-This is because there is no synchronisation whatsoever between the
-writer and the reader.
-
-Fix this by writing data_avail with smp_store_release and reading
-it with smp_load_acquire when we first enter read. The subsequent
-reads are safe because they're either protected by the first load
-acquire, or by the completion mechanism.
-
-Also remove the redundant zeroing of data_idx in random_recv_done
-(data_idx must already be zero at this point) and data_avail in
-request_entropy (ditto).
-

-Subject: i2c: Convert to platform remove callback returning void
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
-
-[ Upstream commit e190a0c389e60178fba3d532abf936dcae223e7d ]
-
-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 (mostly) ignored
-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.

-Subject: i2c: ocores: use devm_ managed clks
-
-From: Wang Zhang <silver_code@hust.edu.cn>
-
-[ Upstream commit 9e1a1ee93f6b08aad5ee645073f7c7b115f71e15 ]
-
-Smatch complains that:
-drivers/i2c/busses/i2c-ocores.c:704 ocores_i2c_probe()
-warn: missing unwind goto?
-
-If any wrong occurs in ocores_i2c_of_probe, the i2c->clk needs to be
-released. But the function returns directly without freeing the clock.
-
-Fix this by updating the code to use devm_clk_get_optional_enabled()
-instead. Use dev_err_probe() where appropriate as well since we are
-changing those statements.
-
-Fixes: f5f35a92e44a ("i2c: ocores: Add irq support for sparc")

-Subject: IB/hfi1: Fix wrong mmu_node used for user SDMA packet after
- invalidate
-
-From: Brendan Cunningham <bcunningham@cornelisnetworks.com>
-
-[ Upstream commit c9358de193ecfb360c3ce75f27ce839ca0b0bc8c ]
-
-The hfi1 user SDMA pinned-page cache will leave a stale cache entry when
-the cache-entry's virtual address range is invalidated but that cache
-entry is in-use by an outstanding SDMA request.
-
-Subsequent user SDMA requests with buffers in or spanning the virtual
-address range of the stale cache entry will result in packets constructed
-from the wrong memory, the physical pages pointed to by the stale cache
-entry.
-
-To fix this, remove mmu_rb_node cache entries from the mmu_rb_handler
-cache independent of the cache entry's refcount. Add 'struct kref
-refcount' to struct mmu_rb_node and manage mmu_rb_node lifetime with
-kref_get() and kref_put().
-
-mmu_rb_node.refcount makes sdma_mmu_node.refcount redundant. Remove
-'atomic_t refcount' from struct sdma_mmu_node and change sdma_mmu_node
-code to use mmu_rb_node.refcount.
-
-Move the mmu_rb_handler destructor call after a
-wait-for-SDMA-request-completion call so mmu_rb_nodes that need
-mmu_rb_handler's workqueue to queue themselves up for destruction from an
-interrupt context may do so.
-
-Fixes: f48ad614c100 ("IB/hfi1: Move driver out of staging")
-Fixes: 00cbce5cbf88 ("IB/hfi1: Fix bugs with non-PAGE_SIZE-end multi-iovec user SDMA requests")

-Subject: ice: handle extts in the miscellaneous interrupt thread
-
-From: Karol Kolacinski <karol.kolacinski@intel.com>
-
-[ Upstream commit 6e8b2c88fc8cf95ed09de25946b20b7536c88cd5 ]
-
-The ice_ptp_extts_work() and ice_ptp_periodic_work() functions are both
-scheduled on the same kthread worker, pf.ptp.kworker. The
-ice_ptp_periodic_work() function sends to the firmware to interact with the
-PHY, and must block to wait for responses.
-
-This can cause delay in responding to the PFINT_OICR_TSYN_EVNT interrupt
-cause, ultimately resulting in disruption to processing an input signal of
-the frequency is high enough. In our testing, even 100 Hz signals get
-disrupted.
-
-Fix this by instead processing the signal inside the miscellaneous
-interrupt thread prior to handling Tx timestamps.
-
-Use atomic bits in a new pf->misc_thread bitmap in order to safely
-communicate which tasks require processing within the
-ice_misc_intr_thread_fn(). This ensures the communication of desired tasks
-from the ice_misc_intr() are correctly processed without racing even in the
-event that the interrupt triggers again before the thread function exits.
-
-Fixes: 172db5f91d5f ("ice: add support for auxiliary input/output pins")

-Subject: igc: Check if hardware TX timestamping is enabled earlier
-
-From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
-
-[ Upstream commit ce58c7cc8b9910f2bc1d038d7ba60c3f011b2cb2 ]
-
-Before requesting a packet transmission to be hardware timestamped,
-check if the user has TX timestamping enabled. Fixes an issue that if
-a packet was internally forwarded to the NIC, and it had the
-SKBTX_HW_TSTAMP flag set, the driver would mark that timestamp as
-skipped.
-
-In reality, that timestamp was "not for us", as TX timestamp could
-never be enabled in the NIC.
-
-Checking if the TX timestamping is enabled earlier has a secondary
-effect that when TX timestamping is disabled, there's no need to check
-for timestamp timeouts.
-
-We should only take care to free any pending timestamp when TX
-timestamping is disabled, as that skb would never be released
-otherwise.

-Subject: igc: Enable and fix RX hash usage by netstack
-
-From: Jesper Dangaard Brouer <brouer@redhat.com>
-
-[ Upstream commit 84214ab4689f962b4bfc47fc9a5838d25ac4274d ]
-
-When function igc_rx_hash() was introduced in v4.20 via commit 0507ef8a0372
-("igc: Add transmit and receive fastpath and interrupt handlers"), the
-hardware wasn't configured to provide RSS hash, thus it made sense to not
-enable net_device NETIF_F_RXHASH feature bit.
-
-The NIC hardware was configured to enable RSS hash info in v5.2 via commit
-2121c2712f82 ("igc: Add multiple receive queues control supporting"), but
-forgot to set the NETIF_F_RXHASH feature bit.
-
-The original implementation of igc_rx_hash() didn't extract the associated
-pkt_hash_type, but statically set PKT_HASH_TYPE_L3. The largest portions of
-this patch are about extracting the RSS Type from the hardware and mapping
-this to enum pkt_hash_types. This was based on Foxville i225 software user
-manual rev-1.3.1 and tested on Intel Ethernet Controller I225-LM (rev 03).
-
-For UDP it's worth noting that RSS (type) hashing have been disabled both for
-IPv4 and IPv6 (see IGC_MRQC_RSS_FIELD_IPV4_UDP + IGC_MRQC_RSS_FIELD_IPV6_UDP)
-because hardware RSS doesn't handle fragmented pkts well when enabled (can
-cause out-of-order). This results in PKT_HASH_TYPE_L3 for UDP packets, and
-hash value doesn't include UDP port numbers. Not being PKT_HASH_TYPE_L4, have
-the effect that netstack will do a software based hash calc calling into
-flow_dissect, but only when code calls skb_get_hash(), which doesn't
-necessary happen for local delivery.
-
-For QA verification testing I wrote a small bpftrace prog:

-Subject: igc: Fix race condition in PTP tx code
-
-From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
-
-[ Upstream commit 9c50e2b150c8ee0eee5f8154e2ad168cdd748877 ]
-
-Currently, the igc driver supports timestamping only one tx packet at a
-time. During the transmission flow, the skb that requires hardware
-timestamping is saved in adapter->ptp_tx_skb. Once hardware has the
-timestamp, an interrupt is delivered, and adapter->ptp_tx_work is
-scheduled. In igc_ptp_tx_work(), we read the timestamp register, update
-adapter->ptp_tx_skb, and notify the network stack.
-
-While the thread executing the transmission flow (the user process
-running in kernel mode) and the thread executing ptp_tx_work don't
-access adapter->ptp_tx_skb concurrently, there are two other places
-where adapter->ptp_tx_skb is accessed: igc_ptp_tx_hang() and
-igc_ptp_suspend().
-
-igc_ptp_tx_hang() is executed by the adapter->watchdog_task worker
-thread which runs periodically so it is possible we have two threads
-accessing ptp_tx_skb at the same time. Consider the following scenario:
-right after __IGC_PTP_TX_IN_PROGRESS is set in igc_xmit_frame_ring(),
-igc_ptp_tx_hang() is executed. Since adapter->ptp_tx_start hasn't been
-written yet, this is considered a timeout and adapter->ptp_tx_skb is
-cleaned up.
-
-This patch fixes the issue described above by adding the ptp_tx_lock to
-protect access to ptp_tx_skb and ptp_tx_start fields from igc_adapter.
-Since igc_xmit_frame_ring() called in atomic context by the networking
-stack, ptp_tx_lock is defined as a spinlock, and the irq safe variants
-of lock/unlock are used.
-
-With the introduction of the ptp_tx_lock, the __IGC_PTP_TX_IN_PROGRESS
-flag doesn't provide much of a use anymore so this patch gets rid of it.

-Subject: igc: Retrieve TX timestamp during interrupt handling
-
-From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
-
-[ Upstream commit afa141583d82725f682b2fa762cb36a07f58b3f3 ]
-
-When the interrupt is handled, the TXTT_0 bit in the TSYNCTXCTL
-register should already be set and the timestamp value already loaded
-in the appropriate register.
-
-This simplifies the handling, and reduces the latency for retrieving
-the TX timestamp, which increase the amount of TX timestamps that can
-be handled in a given time period.
-
-As the "work" function doesn't run in a workqueue anymore, rename it
-to something more sensible, a event handler.
-
-Using ntpperf[1] we can see the following performance improvements:

-
-From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
-
-[ Upstream commit c789ad7cbebcac5d5f417296c140a1252c689524 ]
-
-There's an hardware issue that can cause missing timestamps. The bug
-is that the interrupt is only cleared if the IGC_TXSTMPH_0 register is
-read.
-
-The bug can cause a race condition if a timestamp is captured at the
-wrong time, and we will miss that timestamp. To reduce the time window
-that the problem is able to happen, in case no timestamp was ready, we
-read the "previous" value of the timestamp registers, and we compare
-with the "current" one, if it didn't change we can be reasonably sure
-that no timestamp was captured. If they are different, we use the new
-value as the captured timestamp.
-
-The HW bug is not easy to reproduce, got to reproduce it when smashing
-the NIC with timestamping requests from multiple applications (e.g.
-multiple ntpperf instances + ptp4l), after 10s of minutes.
-
-This workaround has more impact when multiple timestamp registers are
-used, and the IGC_TXSTMPH_0 register always need to be read, so the
-interrupt is cleared.

-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit 767d83361aaa6a1ecb4d5b89eeb38a267239917a ]
-
-The Nokia 770 is using GPIOs from the global numberspace on the
-CBUS node to pass down to the LCD controller. This regresses when we
-let the OMAP GPIO driver use dynamic GPIO base.
-
-The Nokia 770 now has dynamic allocation of IRQ numbers, so this
-needs to be fixed for it to work.
-
-As this is the only user of LCD MIPID we can easily augment the
-driver to use a GPIO descriptor instead and resolve the issue.
-
-The platform data .shutdown() callback wasn't even used in the
-code, but we encode a shutdown asserting RESET in the remove()
-callback for completeness sake.
-
-The CBUS also has the ADS7846 touchscreen attached.
-
-Populate the devices on the Nokia 770 CBUS I2C using software
-nodes instead of platform data quirks. This includes the LCD
-and the ADS7846 touchscreen so the conversion just brings the LCD
-along with it as software nodes is an all-or-nothing design
-pattern.
-
-The ADS7846 has some limited support for using GPIO descriptors,
-let's convert it over completely to using device properties and then
-fix all remaining boardfile users to provide all platform data using
-software nodes.
-
-Dump the of includes and of_match_ptr() in the ADS7846 driver as part
-of the job.
-
-Since we have to move ADS7846 over to obtaining the GPIOs it is
-using exclusively from descriptors, we provide descriptor tables
-for the two remaining in-kernel boardfiles using ADS7846:
-
-- PXA Spitz
-- MIPS Alchemy DB1000 development board
-
-It was too hard for me to include software node conversion of
-these two remaining users at this time: the spitz is using a
-hscync callback in the platform data that would require further
-GPIO descriptor conversion of the Spitz, and moving the hsync
-callback down into the driver: it will just become too big of
-a job, but it can be done separately.
-
-The MIPS Alchemy DB1000 is simply something I cannot test, so take
-the easier approach of just providing some GPIO descriptors in
-this case as I don't want the patch to grow too intrusive.
-
-As we see that several device trees have incorrect polarity flags
-and just expect to bypass the gpiolib polarity handling, fix up
-all device trees too, in a separate patch.

-Subject: Input: cyttsp4_core - change del_timer_sync() to
- timer_shutdown_sync()
-
-From: Duoming Zhou <duoming@zju.edu.cn>
-
-[ Upstream commit dbe836576f12743a7d2d170ad4ad4fd324c4d47a ]
-
-The watchdog_timer can schedule tx_timeout_task and watchdog_work
-can also arm watchdog_timer. The process is shown below:
-
------------ timer schedules work ------------
-cyttsp4_watchdog_timer() //timer handler
- schedule_work(&cd->watchdog_work)
-
------------ work arms timer ------------
-cyttsp4_watchdog_work() //workqueue callback function
- cyttsp4_start_wd_timer()
- mod_timer(&cd->watchdog_timer, ...)
-
-Although del_timer_sync() and cancel_work_sync() are called in
-cyttsp4_remove(), the timer and workqueue could still be rearmed.
-As a result, the possible use after free bugs could happen. The
-process is shown below:
-
- (cleanup routine) | (timer and workqueue routine)
-cyttsp4_remove() | cyttsp4_watchdog_timer() //timer
- cyttsp4_stop_wd_timer() | schedule_work()
- del_timer_sync() |
- | cyttsp4_watchdog_work() //worker
- | cyttsp4_start_wd_timer()
- | mod_timer()
- cancel_work_sync() |
- | cyttsp4_watchdog_timer() //timer
- | schedule_work()
- del_timer_sync() |
- kfree(cd) //FREE |
- | cyttsp4_watchdog_work() // reschedule!
- | cd-> //USE
-
-This patch changes del_timer_sync() to timer_shutdown_sync(),
-which could prevent rearming of the timer from the workqueue.

-[ Upstream commit 8c9cce9cb81b5fdc6e66bf3f129727b89e8daab7 ]
-
-Since PM8998/PM660, the power key debounce register was redefined to
-support shorter debounce times. On PM8941 the shortest debounce time
-(represented by register value 0) was 15625us, on PM8998 the shortest
-debounce time is 62us, with the default being 2ms.

-As per the comments for input_allocate_device() and
-input_register_device(), input_free_device() must be called only to free
-devices that have not been registered. input_unregister_device()
-already calls input_put_device(), thus leading to a use-after-free.
-
-Moreover, the kunit_suite.exit() method is called after every test case,
-even on failures. As the test itself already does cleanups in its
-failure paths, this may lead to a second use-after-free.
-
-Fix the first issue by dropping the call to input_allocate_device() from
-input_test_exit().
-Fix the second issue by making the cleanup code conditional on a
-successful test.

-Subject: iommu/virtio: Detach domain on endpoint release
-
-From: Jean-Philippe Brucker <jean-philippe@linaro.org>
-
-[ Upstream commit 809d0810e3520da669d231303608cdf5fe5c1a70 ]
-
-When an endpoint is released, for example a PCIe VF being destroyed or a
-function hot-unplugged, it should be detached from its domain. Send a
-DETACH request.

-Subject: iommu/virtio: Return size mapped for a detached domain
-
-From: Jean-Philippe Brucker <jean-philippe@linaro.org>
-
-[ Upstream commit 7061b6af34686e7e2364b7240cfb061293218f2d ]
-
-When map() is called on a detached domain, the domain does not exist in
-the device so we do not send a MAP request, but we do update the
-internal mapping tree, to be replayed on the next attach. Since this
-constitutes a successful iommu_map() call, return *mapped in this case
-too.

-Subject: ipvlan: Fix return value of ipvlan_queue_xmit()
-
-From: Cambda Zhu <cambda@linux.alibaba.com>
-
-[ Upstream commit 8a9922e7be6d042fa00f894c376473b17a162b66 ]
-
-ipvlan_queue_xmit() should return NET_XMIT_XXX, but
-ipvlan_xmit_mode_l2/l3() returns rx_handler_result_t or NET_RX_XXX
-in some cases. ipvlan_rcv_frame() will only return RX_HANDLER_CONSUMED
-in ipvlan_xmit_mode_l2/l3() because 'local' is true. It's equal to
-NET_XMIT_SUCCESS. But dev_forward_skb() can return NET_RX_SUCCESS or
-NET_RX_DROP, and returning NET_RX_DROP(NET_XMIT_DROP) will increase
-both ipvlan and ipvlan->phy_dev drops counter.
-
-The skb to forward can be treated as xmitted successfully. This patch
-makes ipvlan_queue_xmit() return NET_XMIT_SUCCESS for forward skb.

-
-[ Upstream commit fb07b8f83441febeb0daf199b5f18c6de9bbab03 ]

-The hierarchy of PCH PIC, PCH PCI MSI and EIONTC is as following:

- PCH PCI MSI --->|
-
-so the irq_data list of irq_desc for IRQs on PCH PIC and PCH PCI MSI

-irq_desc->irq_data(domain: PCH PCI MSI)->parent_data(domain: EIOINTC)
-
-In eiointc_resume(), the irq_data passed into eiointc_set_irq_affinity()
-should be matched to EIOINTC domain instead of PCH PIC or PCH PCI MSI
-domain, so fix it.

-From: Antonio Borneo <antonio.borneo@foss.st.com>
-
-[ Upstream commit 48f31e496488a25f443c0df52464da446fb1d10c ]
-
-While compiling with W=1, both gcc and clang complain about a
-tricky way to initialize an array by filling it with a non-zero
-value and then overrride some of the array elements.
-In this case the override is intentional, so just disable the
-specific warning for only this part of the code.
-
-Note: the flag "-Woverride-init" is recognized by both compilers,
-but the warning msg from clang reports "-Winitializer-overrides".
-The doc of clang clarifies that the two flags are synonyms, so use
-here only the flag name common on both compilers.

-From: Sami Tolvanen <samitolvanen@google.com>
-
-[ Upstream commit 25a21fbb934a0d989e1858f83c2ddf4cfb2ebe30 ]
-
-With GCOV_PROFILE_ALL, Clang injects __llvm_gcov_* functions to each
-object file, including the *.mod.o. As we filter out CC_FLAGS_CFI
-for *.mod.o, the compiler won't generate type hashes for the
-injected functions, and therefore indirectly calling them during
-module loading trips indirect call checking.
-
-Enabling CFI for *.mod.o isn't sufficient to fix this issue after
-commit 0c3e806ec0f9 ("x86/cfi: Add boot time hash randomization"),
-as *.mod.o aren't processed by objtool, which means any hashes
-emitted there won't be randomized. Therefore, in addition to
-disabling CFI for *.mod.o, also disable GCOV, as the object files
-don't otherwise contain any executable code.

-From: Sami Tolvanen <samitolvanen@google.com>
-
-[ Upstream commit ddf56288eebd1fe82c46fc9f693b5b18045cddb6 ]
-
-With GCOV_PROFILE_ALL, Clang injects __llvm_gcov_* functions to
-each object file, and the functions are indirectly called during
-boot. However, when code is injected to object files that are not
-part of vmlinux.o, it's also not processed by objtool, which breaks
-CFI hash randomization as the hashes in these files won't be
-included in the .cfi_sites section and thus won't be randomized.
-
-Similarly to commit 42633ed852de ("kbuild: Fix CFI hash
-randomization with KASAN"), disable GCOV for .vmlinux.export.o and
-init/version-timestamp.o to avoid emitting unnecessary functions to
-object files that don't otherwise have executable code.

-Subject: kexec: fix a memory leak in crash_shrink_memory()
-
-From: Zhen Lei <thunder.leizhen@huawei.com>
-
-[ Upstream commit 1cba6c4309f03de570202c46f03df3f73a0d4c82 ]
-
-Patch series "kexec: enable kexec_crash_size to support two crash kernel
-regions".
-
-When crashkernel=X fails to reserve region under 4G, it will fall back to
-reserve region above 4G and a region of the default size will also be
-reserved under 4G. Unfortunately, /sys/kernel/kexec_crash_size only
-supports one crash kernel region now, the user cannot sense the low memory
-reserved by reading /sys/kernel/kexec_crash_size. Also, low memory cannot
-be freed by writing this file.
-
-For example:
-resource_size(crashk_res) = 512M
-resource_size(crashk_low_res) = 256M
-
-The result of 'cat /sys/kernel/kexec_crash_size' is 512M, but it should be
-768M. When we execute 'echo 0 > /sys/kernel/kexec_crash_size', the size
-of crashk_res becomes 0 and resource_size(crashk_low_res) is still 256 MB,
-which is incorrect.
-
-Since crashk_res manages the memory with high address and crashk_low_res
-manages the memory with low address, crashk_low_res is shrunken only when
-all crashk_res is shrunken. And because when there is only one crash
-kernel region, crashk_res is always used. Therefore, if all crashk_res is
-shrunken and crashk_low_res still exists, swap them.
-
-This patch (of 6):
-
-If the value of parameter 'new_size' is in the semi-open and semi-closed
-interval (crashk_res.end - KEXEC_CRASH_MEM_ALIGN + 1, crashk_res.end], the
-calculation result of ram_res is:
-
- ram_res->start = crashk_res.end + 1
- ram_res->end = crashk_res.end
-
-The operation of insert_resource() fails, and ram_res is not added to
-iomem_resource. As a result, the memory of the control block ram_res is
-leaked.
-
-In fact, on all architectures, the start address and size of crashk_res
-are already aligned by KEXEC_CRASH_MEM_ALIGN. Therefore, we do not need
-to round up crashk_res.start again. Instead, we should round up
-'new_size' in advance.

-In the unlikely case that CLOCK_REALTIME is not defined, variable ret is

-Subject: kunit: tool: undo type subscripts for subprocess.Popen
-
-From: Daniel Latypov <dlatypov@google.com>
-
-[ Upstream commit e30f65c4b3d671115bf2a9d9ef142285387f2aff ]
-
-Writing `subprocess.Popen[str]` requires python 3.9+.
-kunit.py has an assertion that the python version is 3.7+, so we should
-try to stay backwards compatible.
-
-This conflicts a bit with commit 1da2e6220e11 ("kunit: tool: fix
-pre-existing `mypy --strict` errors and update run_checks.py"), since
-mypy complains like so
-> kunit_kernel.py:95: error: Missing type parameters for generic type "Popen" [type-arg]
-
-Note: `mypy --strict --python-version 3.7` does not work.
-
-We could annotate each file with comments like
- `# mypy: disable-error-code="type-arg"
-but then we might still get nudged to break back-compat in other files.
-
-This patch adds a `mypy.ini` file since it seems like the only way to
-disable specific error codes for all our files.
-
-Note: run_checks.py doesn't need to specify `--config_file mypy.ini`,
-but I think being explicit is better, particularly since most kernel
-devs won't be familiar with how mypy works.

-Subject: lib/ts_bm: reset initial match offset for every block of text
-
-From: Jeremy Sowden <jeremy@azazel.net>
-
-[ Upstream commit 6f67fbf8192da80c4db01a1800c7fceaca9cf1f9 ]
-
-The `shift` variable which indicates the offset in the string at which
-to start matching the pattern is initialized to `bm->patlen - 1`, but it
-is not reset when a new block is retrieved. This means the implemen-
-tation may start looking at later and later positions in each successive
-block and miss occurrences of the pattern at the beginning. E.g.,
-consider a HTTP packet held in a non-linear skb, where the HTTP request
-line occurs in the second block:
-
- [... 52 bytes of packet headers ...]
- GET /bmtest HTTP/1.1\r\nHost: www.example.com\r\n\r\n
-
-and the pattern is "GET /bmtest".
-
-Once the first block comprising the packet headers has been examined,
-`shift` will be pointing to somewhere near the end of the block, and so
-when the second block is examined the request line at the beginning will
-be missed.
-
-Reinitialize the variable for each new block.

-Subject: libbpf: btf_dump_type_data_check_overflow needs to consider
- BTF_MEMBER_BITFIELD_SIZE
-
-From: Martin KaFai Lau <martin.lau@kernel.org>
-
-[ Upstream commit c39028b333f3a3a765c5c0b9726b8e38aedf0ba1 ]
-
-The btf_dump/struct_data selftest is failing with:
-
- [...]
- test_btf_dump_struct_data:FAIL:unexpected return value dumping fs_context unexpected unexpected return value dumping fs_context: actual -7 != expected 264
- [...]
-
-The reason is in btf_dump_type_data_check_overflow(). It does not use
-BTF_MEMBER_BITFIELD_SIZE from the struct's member (btf_member). Instead,
-it is using the enum size which is 4. It had been working till the recent
-commit 4e04143c869c ("fs_context: drop the unused lsm_flags member")
-removed an integer member which also removed the 4 bytes padding at the
-end of the fs_context. Missing this 4 bytes padding exposed this bug. In

-Subject: libbpf: fix offsetof() and container_of() to work with CO-RE
-
-From: Andrii Nakryiko <andrii@kernel.org>
-
-[ Upstream commit bdeeed3498c7871c17465bb4f11d1bc67f9098af ]
-
-It seems like __builtin_offset() doesn't preserve CO-RE field
-relocations properly. So if offsetof() macro is defined through
-__builtin_offset(), CO-RE-enabled BPF code using container_of() will be
-subtly and silently broken.
-
-To avoid this problem, redefine offsetof() and container_of() in the
-form that works with CO-RE relocations more reliably.

-Subject: lockd: drop inappropriate svc_get() from locked_get()
-
-From: NeilBrown <neilb@suse.de>
-
-[ Upstream commit 665e89ab7c5af1f2d260834c861a74b01a30f95f ]
-
-The below-mentioned patch was intended to simplify refcounting on the
-svc_serv used by locked. The goal was to only ever have a single
-reference from the single thread. To that end we dropped a call to
-lockd_start_svc() (except when creating thread) which would take a
-reference, and dropped the svc_put(serv) that would drop that reference.
-
-Unfortunately we didn't also remove the svc_get() from
-lockd_create_svc() in the case where the svc_serv already existed.
-So after the patch:
- - on the first call the svc_serv was allocated and the one reference
- was given to the thread, so there are no extra references
- - on subsequent calls svc_get() was called so there is now an extra
- reference.
-This is clearly not consistent.
-
-The inconsistency is also clear in the current code in lockd_get()
-takes *two* references, one on nlmsvc_serv and one by incrementing
-nlmsvc_users. This clearly does not match lockd_put().
-
-So: drop that svc_get() from lockd_get() (which used to be in
-lockd_create_svc().

-Subject: locking/atomic: arm: fix sync ops
-
-From: Mark Rutland <mark.rutland@arm.com>
-
-[ Upstream commit dda5f312bb09e56e7a1c3e3851f2000eb2e9c879 ]
-
-The sync_*() ops on arch/arm are defined in terms of the regular bitops
-with no special handling. This is not correct, as UP kernels elide
-barriers for the fully-ordered operations, and so the required ordering
-is lost when such UP kernels are run under a hypervsior on an SMP
-system.
-
-Fix this by defining sync ops with the required barriers.
-
-Note: On 32-bit arm, the sync_*() ops are currently only used by Xen,
-which requires ARMv7, but the semantics can be implemented for ARMv6+.

-From: Yu Kuai <yukuai3@huawei.com>

-
-Commit 6cce3b23f6f8 ("[PATCH] md: write intent bitmap support for raid10")
-add bitmap support, and it changed that write io is submitted through
-daemon thread because bitmap need to be updated before write io. And
-later, plug is used to fix performance regression because all the write io
-will go to demon thread, which means io can't be issued concurrently.
-
-However, if bitmap is not enabled, the write io should not go to daemon
-thread in the first place, and plug is not needed as well.

-When removing a disk with replacement, the replacement will be used to

-rdev and replacement are read as NULL in raid10_write_request(). This

-Fix it by reading replacement first and rdev later, meanwhile, use smp_mb()

-
-[ Upstream commit 34817a2441747b48e444cb0e05d84e14bc9443da ]
-
-There are two check of 'mreplace' in raid10_sync_request(). In the first
-check, 'need_replace' will be set and 'mreplace' will be used later if
-no-Faulty 'mreplace' exists, In the second check, 'mreplace' will be
-set to NULL if it is Faulty, but 'need_replace' will not be changed
-accordingly. null-ptr-deref occurs if Faulty is set between two check.
-
-Fix it by merging two checks into one. And replace 'need_replace' with
-'mreplace' because their values are always the same.

-From: Paul Cercueil <paul@crapouillou.net>
-
-[ Upstream commit 08384e80a70fb1942510ab5f0ce27bad134e634e ]
-
-The Device Tree was using invalid node names for the ACT8600 regulators.
-To be fair, it is not the original committer's fault, as the
-documentation did gives invalid names as well.
-
-In theory, the fix should have been to modify the driver to accept the
-alternative names. However, even though the act8865 driver spits
-warnings, the kernel seemed to work fine with what is currently
-supported upstream. For that reason, I think it is okay to just update
-the DTS.
-
-I removed the "regulator-name" too, since they really didn't bring any
-information. The node names are enough.

-Subject: MIPS: DTS: CI20: Raise VDDCORE voltage to 1.125 volts
-
-From: Paul Cercueil <paul@crapouillou.net>
-
-[ Upstream commit 944520f85d5b1fb2f9ea243be41f9c9af3d4cef3 ]
-
-Commit 08384e80a70f ("MIPS: DTS: CI20: Fix ACT8600 regulator node
-names") caused the VDDCORE power supply (regulated by the ACT8600's
-DCDC1 output) to drop from a voltage of 1.2V configured by the
-bootloader, to the 1.1V set in the Device Tree.
-
-According to the documentation, the VDDCORE supply should be between
-0.99V and 1.21V; both values are therefore within the supported range.
-
-However, VDDCORE being 1.1V results in the CI20 being very unstable,
-with corrupted memory, failures to boot, or reboots at random. The
-reason might be succint drops of the voltage below the minimum required.
-
-Raising the minimum voltage to 1.125 volts seems to be enough to address
-this issue, while still keeping a relatively low core voltage which
-helps for power consumption and thermals.

-Subject: mm: move mm_count into its own cache line
-
-From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
-
-[ Upstream commit c1753fd02a0058ea43cbb31ab26d25be2f6cfe08 ]
-
-The mm_struct mm_count field is frequently updated by mmgrab/mmdrop
-performed by context switch. This causes false-sharing for surrounding
-mm_struct fields which are read-mostly.
-
-This has been observed on a 2sockets/112core/224cpu Intel Sapphire Rapids
-server running hackbench, and by the kernel test robot will-it-scale
-testcase.
-
-Move the mm_count field into its own cache line to prevent false-sharing
-with other mm_struct fields.
-
-Move mm_count to the first field of mm_struct to minimize the amount of
-padding required: rather than adding padding before and after the mm_count
-field, padding is only added after mm_count.
-
-Note that I noticed this odd comment in mm_struct:
-
-commit 2e3025434a6b ("mm: relocate 'write_protect_seq' in struct mm_struct")
-
- /*
- * With some kernel config, the current mmap_lock's offset
- * inside 'mm_struct' is at 0x120, which is very optimal, as
- * its two hot fields 'count' and 'owner' sit in 2 different
- * cachelines, and when mmap_lock is highly contended, both
- * of the 2 fields will be accessed frequently, current layout
- * will help to reduce cache bouncing.
- *
- * So please be careful with adding new fields before
- * mmap_lock, which can easily push the 2 fields into one
- * cacheline.
- */
- struct rw_semaphore mmap_lock;
-
-This comment is rather odd for a few reasons:
-
-- It requires addition/removal of mm_struct fields to carefully consider
- field alignment of _other_ fields,
-- It expresses the wish to keep an "optimal" alignment for a specific
- kernel config.
-
-I suspect that the author of this comment may want to revisit this topic
-and perhaps introduce a split-struct approach for struct rw_semaphore,
-if the need is to place various fields of this structure in different
-cache lines.

-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit a3332b7aad346b14770797e03ddd02ebdb14db41 ]
-
-When I boot a kukui-kodama board, I see an ugly warning in my kernel
-log:
- mtk-msdc 11240000.mmc: error -ENXIO: IRQ sdio_wakeup not found
-
-It's pretty normal not to have an "sdio_wakeup" IRQ defined. In fact,
-no device trees in mainline seem to have it. Let's use the
-platform_get_irq_byname_optional() to avoid the error message.

-Subject: modpost: remove broken calculation of exception_table_entry size
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-[ Upstream commit d0acc76a49aa917c1a455d11d32d34a01e8b2835 ]
-
-find_extable_entry_size() is completely broken. It has awesome comments
-about how to calculate sizeof(struct exception_table_entry).
-
-It was based on these assumptions:
-
- - struct exception_table_entry has two fields
- - both of the fields have the same size
-
-Then, we came up with this equation:
-
- (offset of the second field) * 2 == (size of struct)
-
-It was true for all architectures when commit 52dc0595d540 ("modpost:
-handle relocations mismatch in __ex_table.") was applied.
-
-Our mathematics broke when commit 548acf19234d ("x86/mm: Expand the
-exception table logic to allow new handling options") introduced the
-third field.
-
-Now, the definition of exception_table_entry is highly arch-dependent.
-
-For x86, sizeof(struct exception_table_entry) is apparently 12, but
-find_extable_entry_size() sets extable_entry_size to 8.
-
-I could fix it, but I do not see much value in this code.
-
-extable_entry_size is used just for selecting a slightly different
-error message.
-
-If the first field ("insn") references to a non-executable section,
-
- The relocation at %s+0x%lx references
- section "%s" which is not executable, IOW
- it is not possible for the kernel to fault
- at that address. Something is seriously wrong
- and should be fixed.
-
-If the second field ("fixup") references to a non-executable section,
-
- The relocation at %s+0x%lx references
- section "%s" which is not executable, IOW
- the kernel will fault if it ever tries to
- jump to it. Something is seriously wrong
- and should be fixed.
-
-Merge the two error messages rather than adding even more complexity.
-
-Change fatal() to error() to make it continue running and catch more

-Subject: net: axienet: Move reset before 64-bit DMA detection
-
-From: Maxim Kochetkov <fido_max@inbox.ru>
-
-[ Upstream commit f1bc9fc4a06de0108e0dca2a9a7e99ba1fc632f9 ]
-
-64-bit DMA detection will fail if axienet was started before (by boot
-loader, boot ROM, etc). In this state axienet will not start properly.
-XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
-64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
-(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
-is used to fetch the first descriptor. So iowrite32()/ioread32() trick
-to this register to detect 64-bit DMA will not work.
-So move axienet reset before 64-bit DMA detection.

-Subject: net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC
- addresses
-
-From: Vladimir Oltean <vladimir.oltean@nxp.com>
-
-[ Upstream commit d06f925f13976ab82167c93467c70a337a0a3cda ]
-
-When using the felix driver (the only one which supports UC filtering
-and MC filtering) as a DSA master for a random other DSA switch, one can
-see the following stack trace when the downstream switch ports join a
-VLAN-aware bridge:
-
-=============================
-WARNING: suspicious RCU usage
------------------------------
-net/8021q/vlan_core.c:238 suspicious rcu_dereference_protected() usage!
-
-stack backtrace:
-Workqueue: dsa_ordered dsa_slave_switchdev_event_work
-Call trace:
- lockdep_rcu_suspicious+0x170/0x210
- vlan_for_each+0x8c/0x188
- dsa_slave_sync_uc+0x128/0x178
- __hw_addr_sync_dev+0x138/0x158
- dsa_slave_set_rx_mode+0x58/0x70
- __dev_set_rx_mode+0x88/0xa8
- dev_uc_add+0x74/0xa0
- dsa_port_bridge_host_fdb_add+0xec/0x180
- dsa_slave_switchdev_event_work+0x7c/0x1c8
- process_one_work+0x290/0x568
-
-What it's saying is that vlan_for_each() expects rtnl_lock() context and
-it's not getting it, when it's called from the DSA master's ndo_set_rx_mode().
-
-The caller of that - dsa_slave_set_rx_mode() - is the slave DSA
-interface's dsa_port_bridge_host_fdb_add() which comes from the deferred
-dsa_slave_switchdev_event_work().
-
-We went to great lengths to avoid the rtnl_lock() context in that call
-path in commit 0faf890fc519 ("net: dsa: drop rtnl_lock from
-dsa_slave_switchdev_event_work"), and calling rtnl_lock() is simply not
-an option due to the possibility of deadlocking when calling
-dsa_flush_workqueue() from the call paths that do hold rtnl_lock() -
-basically all of them.
-
-So, when the DSA master calls vlan_for_each() from its ndo_set_rx_mode(),
-the state of the 8021q driver on this device is really not protected
-from concurrent access by anything.
-
-Looking at net/8021q/, I don't think that vlan_info->vid_list was
-particularly designed with RCU traversal in mind, so introducing an RCU
-read-side form of vlan_for_each() - vlan_for_each_rcu() - won't be so
-easy, and it also wouldn't be exactly what we need anyway.
-
-In general I believe that the solution isn't in net/8021q/ anyway;
-vlan_for_each() is not cut out for this task. DSA doesn't need rtnl_lock()
-to be held per se - since it's not a netdev state change that we're
-blocking, but rather, just concurrent additions/removals to a VLAN list.
-We don't even need sleepable context - the callback of vlan_for_each()
-just schedules deferred work.
-
-The proposed escape is to remove the dependency on vlan_for_each() and
-to open-code a non-sleepable, rtnl-free alternative to that, based on
-copies of the VLAN list modified from .ndo_vlan_rx_add_vid() and
-.ndo_vlan_rx_kill_vid().

-Subject: net: nfc: Fix use-after-free caused by nfc_llcp_find_local
-
-From: Lin Ma <linma@zju.edu.cn>
-
-[ Upstream commit 6709d4b7bc2e079241fdef15d1160581c5261c10 ]
-
-This commit fixes several use-after-free that caused by function
-nfc_llcp_find_local(). For example, one UAF can happen when below buggy
-time window occurs.
-
-// nfc_genl_llc_get_params | // nfc_unregister_device
- |
-dev = nfc_get_device(idx); | device_lock(...)
-if (!dev) | dev->shutting_down = true;
- return -ENODEV; | device_unlock(...);
- |
-device_lock(...); | // nfc_llcp_unregister_device
- | nfc_llcp_find_local()
-nfc_llcp_find_local(...); |
- | local_cleanup()
-if (!local) { |
- rc = -ENODEV; | // nfc_llcp_local_put
- goto exit; | kref_put(.., local_release)
-} |
- | // local_release
- | list_del(&local->list)
- // nfc_genl_send_params | kfree()
- local->dev->idx !!!UAF!!! |
- |
-
-and the crash trace for the one of the discussed UAF like:

-
-In summary, this patch solves those use-after-free by
-
-1. Re-implement the nfc_llcp_find_local(). The current version does not
-grab the reference when getting the local from the linked list. For
-example, the llcp_sock_bind() gets the reference like below:
-
-// llcp_sock_bind()
-
- local = nfc_llcp_find_local(dev); // A
- ..... \
- | raceable
- ..... /
- llcp_sock->local = nfc_llcp_local_get(local); // B
-
-There is an apparent race window that one can drop the reference
-and free the local object fetched in (A) before (B) gets the reference.
-
-2. Some callers of the nfc_llcp_find_local() do not grab the reference
-at all. For example, the nfc_genl_llc_{{get/set}_params/sdreq} functions.
-We add the nfc_llcp_local_put() for them. Moreover, we add the necessary
-error handling function to put the reference.
-
-3. Add the nfc_llcp_remove_local() helper. The local object is removed
-from the linked list in local_release() when all reference is gone. This
-patch removes it when nfc_llcp_unregister_device() is called.
-
-Therefore, every caller of nfc_llcp_find_local() will get a reference
-even when the nfc_llcp_unregister_device() is called. This promises no
-use-after-free for the local object is ever possible.
-
-Fixes: 52feb444a903 ("NFC: Extend netlink interface for LTO, RW, and MIUX parameters support")
-Fixes: c7aa12252f51 ("NFC: Take a reference on the LLCP local pointer when creating a socket")

-
-From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
-
-[ Upstream commit c4fc88ad2a765224a648db8ab35f125e120fe41b ]
-
-Commit 49725ffc15fc ("net: stmmac: power up/down serdes in
-stmmac_open/release") correctly added a call to the serdes_powerdown()
-callback to stmmac_release() but did not remove the one from
-stmmac_remove() which leads to a doubled call to serdes_powerdown().
-
-This can lead to all kinds of problems: in the case of the qcom ethqos
-driver, it caused an unbalanced regulator disable splat.

-Subject: netfilter: conntrack: dccp: copy entire header to stack buffer, not
- just basic one
-
-From: Florian Westphal <fw@strlen.de>
-
-[ Upstream commit ff0a3a7d52ff7282dbd183e7fc29a1fe386b0c30 ]
-
-Eric Dumazet says:
- nf_conntrack_dccp_packet() has an unique:
-
- dh = skb_header_pointer(skb, dataoff, sizeof(_dh), &_dh);
-
- And nothing more is 'pulled' from the packet, depending on the content.
- dh->dccph_doff, and/or dh->dccph_x ...)
- So dccp_ack_seq() is happily reading stuff past the _dh buffer.
-
-BUG: KASAN: stack-out-of-bounds in nf_conntrack_dccp_packet+0x1134/0x11c0
-Read of size 4 at addr ffff000128f66e0c by task syz-executor.2/29371
-[..]
-
-Fix this by increasing the stack buffer to also include room for
-the extra sequence numbers and all the known dccp packet type headers,
-then pull again after the initial validation of the basic header.
-
-While at it, mark packets invalid that lack 48bit sequence bit but
-where RFC says the type MUST use them.
-
-Compile tested only.
-
-v2: first skb_header_pointer() now needs to adjust the size to
- only pull the generic header. (Eric)
-
-Heads-up: I intend to remove dccp conntrack support later this year.

- return value.
-
-From: Ilia.Gavrilov <Ilia.Gavrilov@infotecs.ru>
-
-[ Upstream commit f188d30087480eab421cd8ca552fb15f55d57f4d ]
-
-ct_sip_parse_numerical_param() returns only 0 or 1 now.
-But process_register_request() and process_register_response() imply
-checking for a negative value if parsing of a numerical header parameter
-failed.
-The invocation in nf_nat_sip() looks correct:
- if (ct_sip_parse_numerical_param(...) > 0 &&
- ...) { ... }
-
-Make the return value of the function ct_sip_parse_numerical_param()
-a tristate to fix all the cases
-a) return 1 if value is found; *val is set
-b) return 0 if value is not found; *val is unchanged
-c) return -1 on error; *val is undefined
-
-Found by InfoTeCS on behalf of Linux Verification Center
-(linuxtesting.org) with SVACE.

-
-[ Upstream commit b389139f12f287b8ed2e2628b72df89a081f0b59 ]
-
-Set element addition error path decrements reference counter on chains
-twice: once on element release and again via nft_data_release().
-
-Then, d6b478666ffa ("netfilter: nf_tables: fix underflow in object
-reference counter") incorrectly fixed this by removing the stateful
-object reference count decrement.
-
-Restore the stateful object decrement as in b91d90368837 ("netfilter:
-nf_tables: fix leaking object reference count") and let
-nft_data_release() decrement the chain reference counter, so this is
-done only once.

-Subject: netlink: Add __sock_i_ino() for __netlink_diag_dump().
-
-From: Kuniyuki Iwashima <kuniyu@amazon.com>
-
-[ Upstream commit 25a9c8a4431c364f97f75558cb346d2ad3f53fbb ]
-
-syzbot reported a warning in __local_bh_enable_ip(). [0]
-
-Commit 8d61f926d420 ("netlink: fix potential deadlock in
-netlink_set_err()") converted read_lock(&nl_table_lock) to
-read_lock_irqsave() in __netlink_diag_dump() to prevent a deadlock.
-
-However, __netlink_diag_dump() calls sock_i_ino() that uses
-read_lock_bh() and read_unlock_bh(). If CONFIG_TRACE_IRQFLAGS=y,
-read_unlock_bh() finally enables IRQ even though it should stay
-disabled until the following read_unlock_irqrestore().
-
-Using read_lock() in sock_i_ino() would trigger a lockdep splat
-in another place that was fixed in commit f064af1e500a ("net: fix
-a lockdep splat"), so let's add __sock_i_ino() that would be safe
-to use under BH disabled.

-Subject: netlink: fix potential deadlock in netlink_set_err()
-
-From: Eric Dumazet <edumazet@google.com>
-
-[ Upstream commit 8d61f926d42045961e6b65191c09e3678d86a9cf ]
-
-syzbot reported a possible deadlock in netlink_set_err() [1]
-
-A similar issue was fixed in commit 1d482e666b8e ("netlink: disable IRQs
-for netlink_lock_table()") in netlink_lock_table()
-
-This patch adds IRQ safety to netlink_set_err() and __netlink_diag_dump()
-which were not covered by cited commit.
-
-[1]
-
-WARNING: possible irq lock inversion dependency detected
-6.4.0-rc6-syzkaller-00240-g4e9f0ec38852 #0 Not tainted
-
-syz-executor.2/23011 just changed the state of lock:
-ffffffff8e1a7a58 (nl_table_lock){.+.?}-{2:2}, at: netlink_set_err+0x2e/0x3a0 net/netlink/af_netlink.c:1612
-but this lock was taken by another, SOFTIRQ-safe lock in the past:
- (&local->queue_stop_reason_lock){..-.}-{2:2}
-
-and interrupts could create inverse lock ordering between them.
-
-other info that might help us debug this:
- Possible interrupt unsafe locking scenario:
-
- CPU0 CPU1

-Subject: NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
-
-From: Olga Kornievskaia <kolga@netapp.com>
-
-[ Upstream commit c907e72f58ed979a24a9fdcadfbc447c51d5e509 ]
-
-When the client received NFS4ERR_BADSESSION, it schedules recovery
-and start the state manager thread which in turn freezes the
-session table and does not allow for any new requests to use the
-no-longer valid session. However, it is possible that before
-the state manager thread runs, a new operation would use the
-released slot that received BADSESSION and was therefore not
-updated its sequence number. Such re-use of the slot can lead
-the application errors.

-Subject: NFSv4.2: fix wrong shrinker_id
-
-From: Qi Zheng <zhengqi.arch@bytedance.com>
-
-[ Upstream commit 7f7ab336898f281e58540ef781a8fb375acc32a9 ]
-
-Currently, the list_lru::shrinker_id corresponding to the nfs4_xattr
-shrinkers is wrong:
-
->>> prog["nfs4_xattr_cache_lru"].shrinker_id
-(int)0
->>> prog["nfs4_xattr_entry_lru"].shrinker_id
-(int)0
->>> prog["nfs4_xattr_large_entry_lru"].shrinker_id
-(int)0
->>> prog["nfs4_xattr_cache_shrinker"].id
-(int)18
->>> prog["nfs4_xattr_entry_shrinker"].id
-(int)19
->>> prog["nfs4_xattr_large_entry_shrinker"].id
-(int)20
-
-This is not what we expect, which will cause these shrinkers
-not to be found in shrink_slab_memcg().
-
-We should assign shrinker::id before calling list_lru_init_memcg(),
-so that the corresponding list_lru::shrinker_id will be assigned
-the correct value like below:
-
->>> prog["nfs4_xattr_cache_lru"].shrinker_id
-(int)16
->>> prog["nfs4_xattr_entry_lru"].shrinker_id
-(int)17
->>> prog["nfs4_xattr_large_entry_lru"].shrinker_id
-(int)18
->>> prog["nfs4_xattr_cache_shrinker"].id
-(int)16
->>> prog["nfs4_xattr_entry_shrinker"].id
-(int)17
->>> prog["nfs4_xattr_large_entry_shrinker"].id
-(int)18
-
-So just do it.

-Subject: ocfs2: Fix use of slab data with sendpage
-
-From: David Howells <dhowells@redhat.com>
-
-[ Upstream commit 86d7bd6e66e9925f0f04a7bcf3c92c05fdfefb5a ]
-
-ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
-o2net_keep_resp and then passes these to sendpage. This isn't really
-allowed as the lifetime of slab objects is not controlled by page ref -
-though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
-will, however, print a warning and give an error.
-
-Fix it to use folio_alloc() instead to allocate a buffer for the handshake
-message, keepalive request and reply messages.

-Subject: PCI/ASPM: Disable ASPM on MFD function removal to avoid
- use-after-free
-
-From: Ding Hui <dinghui@sangfor.com.cn>
-
-[ Upstream commit 456d8aa37d0f56fc9e985e812496e861dcd6f2f2 ]
-
-Struct pcie_link_state->downstream is a pointer to the pci_dev of function
-0. Previously we retained that pointer when removing function 0, and
-subsequent ASPM policy changes dereferenced it, resulting in a
-use-after-free warning from KASAN, e.g.:
-
- # echo 1 > /sys/bus/pci/devices/0000:03:00.0/remove
- # echo powersave > /sys/module/pcie_aspm/parameters/policy
-
- BUG: KASAN: slab-use-after-free in pcie_config_aspm_link+0x42d/0x500
- Call Trace:
- kasan_report+0xae/0xe0
- pcie_config_aspm_link+0x42d/0x500
- pcie_aspm_set_policy+0x8e/0x1a0
- param_attr_store+0x162/0x2c0
- module_attr_store+0x3e/0x80
-
-PCIe spec r6.0, sec 7.5.3.7, recommends that software program the same ASPM
-Control value in all functions of multi-function devices.
-
-Disable ASPM and free the pcie_link_state when any child function is
-removed so we can discard the dangling pcie_link_state->downstream pointer
-and maintain the same ASPM Control configuration for all functions.

-Subject: PCI: cadence: Fix Gen2 Link Retraining process
-
-From: Siddharth Vadapalli <s-vadapalli@ti.com>
-
-[ Upstream commit 0e12f830236928b6fadf40d917a7527f0a048d2f ]
-
-The Link Retraining process is initiated to account for the Gen2 defect in
-the Cadence PCIe controller in J721E SoC. The errata corresponding to this
-is i2085, documented at:
-https://www.ti.com/lit/er/sprz455c/sprz455c.pdf
-
-The existing workaround implemented for the errata waits for the Data Link
-initialization to complete and assumes that the link retraining process
-at the Physical Layer has completed. However, it is possible that the
-Physical Layer training might be ongoing as indicated by the
-PCI_EXP_LNKSTA_LT bit in the PCI_EXP_LNKSTA register.
-
-Fix the existing workaround, to ensure that the Physical Layer training
-has also completed, in addition to the Data Link initialization.

-
-In pci_epf_test_init_dma_chan() epf_test->dma_chan_rx is assigned from
-dma_request_channel() with DMA_DEV_TO_MEM as filter.dma_mask.
-
-However, in pci_epf_test_data_transfer() if the dir is DMA_DEV_TO_MEM,

-Subject: PCI: ftpci100: Release the clock resources
-
-From: Junyan Ye <yejunyan@hust.edu.cn>
-
-[ Upstream commit c60738de85f40b0b9f5cb23c21f9246e5a47908c ]
-
-Smatch reported:
-1. drivers/pci/controller/pci-ftpci100.c:526 faraday_pci_probe() warn:
-'clk' from clk_prepare_enable() not released on lines: 442,451,462,478,512,517.
-2. drivers/pci/controller/pci-ftpci100.c:526 faraday_pci_probe() warn:
-'p->bus_clk' from clk_prepare_enable() not released on lines: 451,462,478,512,517.
-
-The clock resource is obtained by devm_clk_get(), and then
-clk_prepare_enable() makes the clock resource ready for use. After that,
-clk_disable_unprepare() should be called to release the clock resource
-when it is no longer needed. However, while doing some error handling
-in faraday_pci_probe(), clk_disable_unprepare() is not called to release
-clk and p->bus_clk before returning. These return lines are exactly 442,
-451, 462, 478, 512, 517.
-
-Fix this warning by replacing devm_clk_get() with devm_clk_get_enabled(),
-which is equivalent to devm_clk_get() + clk_prepare_enable(). And with
-devm_clk_get_enabled(), the clock will automatically be disabled,
-unprepared and freed when the device is unbound from the bus.

-Subject: PCI: pciehp: Cancel bringup sequence if card is not present
-
-From: Rongguang Wei <weirongguang@kylinos.cn>
-
-[ Upstream commit e8afd0d9fccc27c8ad263db5cf5952cfcf72d6fe ]
-
-If a PCIe hotplug slot has an Attention Button, the normal hot-add flow is:
-
- - Slot is empty and slot power is off
- - User inserts card in slot and presses Attention Button
- - OS blinks Power Indicator for 5 seconds
- - After 5 seconds, OS turns on Power Indicator, turns on slot power, and
- enumerates the device
-
-Previously, if a user pressed the Attention Button on an *empty* slot,
-pciehp logged the following messages and blinked the Power Indicator
-until a second button press:
-
- [0.000] pciehp: Button press: will power on in 5 sec
- [0.001] # Power Indicator starts blinking
- [5.001] # 5 second timeout; slot is empty, so we should cancel the
- request to power on and turn off Power Indicator
-
- [7.000] # Power Indicator still blinking
- [8.000] # possible card insertion
- [9.000] pciehp: Button press: canceling request to power on
-
-The first button press incorrectly left the slot in BLINKINGON_STATE, so
-the second was interpreted as a "cancel power on" event regardless of
-whether a card was present.
-
-If the slot is empty, turn off the Power Indicator and return from
-BLINKINGON_STATE to OFF_STATE after 5 seconds, effectively canceling the
-request to power on. Putting the slot in OFF_STATE also means the second
-button press will correctly request a slot power on if the slot is
-occupied.

-
-[ Upstream commit 60f0072d7fb7996b9a524ef0d152e21205473192 ]

-
-The ret variable in the vmd_enable_domain() function was used

-the pci_reset_bus() function.
-
-Thus, fix the issue by assigning ret with the value returned from

-Subject: PCI: vmd: Reset VMD config register between soft reboots
-
-From: Nirmal Patel <nirmal.patel@linux.intel.com>
-
-[ Upstream commit b61cf04c49c3dfa70a0d6725d3eb40bf9b35cf71 ]
-
-VMD driver can disable or enable MSI remapping by changing
-VMCONFIG_MSI_REMAP register. This register needs to be set to the
-default value during soft reboots. Drives failed to enumerate
-when Windows boots after performing a soft reboot from Linux.
-Windows doesn't support MSI remapping disable feature and stale
-register value hinders Windows VMD driver initialization process.
-Adding vmd_shutdown function to make sure to set the VMCONFIG
-register to the default value.

-Subject: perf/arm-cmn: Fix DTC reset
-
-From: Robin Murphy <robin.murphy@arm.com>
-
-[ Upstream commit 71746c995cac92fcf6a65661b51211cf2009d7f0 ]
-
-It turns out that my naive DTC reset logic fails to work as intended,
-since, after checking with the hardware designers, the PMU actually
-needs to be fully enabled in order to correctly clear any pending
-overflows. Therefore, invert the sequence to start with turning on both
-enables so that we can reliably get the DTCs into a known state, then
-moving to our normal counters-stopped state from there. Since all the
-DTM counters have already been unpaired during the initial discovery
-pass, we just need to additionally reset the cycle counters to ensure
-that no other unexpected overflows occur during this period.

-Subject: perf/ibs: Fix interface via core pmu events
-
-From: Ravi Bangoria <ravi.bangoria@amd.com>
-
-[ Upstream commit 2fad201fe38ff9a692acedb1990ece2c52a29f95 ]
-
-Although, IBS pmus can be invoked via their own interface, indirect
-IBS invocation via core pmu events is also supported with fixed set
-of events: cpu-cycles:p, r076:p (same as cpu-cycles:p) and r0C1:p
-(micro-ops) for user convenience.
-
-This indirect IBS invocation is broken since commit 66d258c5b048
-("perf/core: Optimize perf_init_event()"), which added RAW pmu under
-'pmu_idr' list and thus if event_init() fails with RAW pmu, it started
-returning error instead of trying other pmus.
-
-Forward precise events from core pmu to IBS by overwriting 'type' and
-'config' in the kernel copy of perf_event_attr. Overwriting will cause
-perf_init_event() to retry with updated 'type' and 'config', which will
-automatically forward event to IBS pmu.
-
-Without patch:
- $ sudo ./perf record -C 0 -e r076:p -- sleep 1
- Error:
- The r076:p event is not supported.
-
-With patch:
- $ sudo ./perf record -C 0 -e r076:p -- sleep 1
- [ perf record: Woken up 1 times to write data ]

-Subject: perf script: Fix allocation of evsel->priv related to per-event dump
- files
-
-From: Arnaldo Carvalho de Melo <acme@redhat.com>
-
-[ Upstream commit 36d3e4138e1b6cc9ab179f3f397b5548f8b1eaae ]
-
-When printing output we may want to generate per event files, where the
---per-event-dump option should be used, creating perf.data.EVENT.dump
-files instead of printing to stdout.
-
-The callback thar processes event thus expects that evsel->priv->fp
-should point to either the per-event FILE descriptor or to stdout.
-
-The a3af66f51bd0bca7 ("perf script: Fix crash because of missing
-evsel->priv") changeset fixed a case where evsel->priv wasn't setup,
-thus set to NULL, causing a segfault when trying to access
-evsel->priv->fp.
-
-But it did it for the non --per-event-dump case by allocating a 'struct
-perf_evsel_script' just to set its ->fp to stdout.
-
-Since evsel->priv is only freed when --per-event-dump is used, we ended
-up with a memory leak, detected using ASAN.
-
-Fix it by using the same method as perf_script__setup_per_event_dump(),
-and reuse that static 'struct perf_evsel_script'.
-
-Also check if evsel_script__new() failed.

-looks like from wherever `check_exec_0` is called.
-
-This issue due to ${$1} caused all function calls to give error in

-Subject: perf tests task_analyzer: Skip tests if no libtraceevent support
-
-From: Aditya Gupta <adityag@linux.ibm.com>
-
-[ Upstream commit c3ac3b0779770acd3ad7eecb5099ab4419ef2e2e ]
-
-Test "perf script task-analyzer tests" fails in environment with missing
-libtraceevent support, as perf record fails to create the perf.data
-file, which further tests depend on.
-
-Instead, when perf is not compiled with libtraceevent support, skip
-those tests instead of failing them, by checking the output of `perf
-record --dry-run` to see if it prints the error "libtraceevent is
-necessary for tracepoint support"
-
-For the following output, perf compiled with: `make NO_LIBTRACEEVENT=1`
-
-Before the patch:
-
-108: perf script task-analyzer tests :
-test child forked, pid 24105
-failed to open perf.data: No such file or directory (try 'perf record' first)
-FAIL: "invokation of perf script report task-analyzer command failed" Error message: ""
-FAIL: "test_basic" Error message: "Failed to find required string:'Comm'."
-failed to open perf.data: No such file or directory (try 'perf record' first)
-FAIL: "invokation of perf script report task-analyzer --ns --rename-comms-by-tids 0:random command failed" Error message: ""
-FAIL: "test_ns_rename" Error message: "Failed to find required string:'Comm'."
-failed to open perf.data: No such file or directory (try 'perf record' first)
-<...>
-perf script task-analyzer tests: FAILED!
-
-With this patch, the script instead returns 2 signifying SKIP, and after
-the patch:
-
-108: perf script task-analyzer tests :
-test child forked, pid 26010
-libtraceevent is necessary for tracepoint support
-WARN: Skipping tests. No libtraceevent support
-test child finished with -2

-Subject: pinctrl: freescale: Fix a memory out of bounds when num_configs is 1
-
-From: Xiaolei Wang <xiaolei.wang@windriver.com>
-
-[ Upstream commit 9063777ca1e2e895c5fdd493ee0c3f18fa710ed4 ]
-
-The config passed in by pad wakeup is 1, when num_configs is 1,
-Configuration [1] should not be fetched, which will be detected
-by KASAN as a memory out of bounds condition. Modify to get
-configs[1] when num_configs is 2.

-
-From: Thierry Reding <treding@nvidia.com>

-[ Upstream commit fad57233501beb5bd25f037cb9128a533e710600 ]
-
-The function table is filled with group information based on other
-instance-specific data at runtime. However, the function table can be
-shared between multiple instances, causing the ->probe() function for
-one instance to overwrite the table of a previously probed instance.
-
-Fix this by sharing only the function names and allocating a separate
-function table for each instance.

-[ Upstream commit 966cca72ab20289083521a385fa56035d85a222d ]
-
-Currently rbtn_add() in case of failure is leaking resources. Fix this
-by adding a proper rollback. Move devm_kzalloc() before rbtn_acquire(),
-so it doesn't require rollback in case of failure. While at it, remove
-unnecessary assignment of NULL to device->driver_data and unnecessary
-whitespace, plus add a break for the default case in a switch.

-
-[ Upstream commit 416a87c972b978d71ab828442d1d48e3bd194855 ]
-
-commit c5ad454a12c6 ("platform/x86: intel/pmc/core: Add Meteor Lake
-support to pmc core driver") was supposed to add support for Meter
-Lake P/M and mistakenly added support for Meteor Lake S instead. Meteor
-Lake P/M support was added later and MTL-S support needs to be removed
-since its currently assigned to the wrong register maps.

-Subject: platform/x86: lenovo-yogabook: Fix work race on remove()
-
-From: Hans de Goede <hdegoede@redhat.com>
-
-[ Upstream commit 9148cd2eb4450a8e9c49c8a14201fb82f651128f ]
-
-When yogabook_wmi_remove() runs yogabook_wmi_work might still be running
-and using the devices which yogabook_wmi_remove() puts.
-
-To avoid this move to explicitly cancelling the work rather then using
-devm_work_autocancel().
-
-This requires also making the yogabook_backside_hall_irq handler non
-devm managed, so that it cannot re-queue the work while
-yogabook_wmi_remove() runs.
-
-Fixes: c0549b72d99d ("platform/x86: lenovo-yogabook-wmi: Add driver for Lenovo Yoga Book")

-From: Hans de Goede <hdegoede@redhat.com>
-
-[ Upstream commit 711bcc0cb34e96a60e88d7b0260862781de3e530 ]
-
-Ensure that both the keyboard touchscreen and the digitizer have their
-driver bound after remove(). Without this modprobing lenovo-yogabook-wmi
-after a rmmod fails because lenovo-yogabook-wmi defers probing until
-both devices have their driver bound.

-From: Thomas Gleixner <tglx@linutronix.de>
-
-[ Upstream commit 9d9e522010eb5685d8b53e8a24320653d9d4cbbf ]
-
-itimer_delete() has a retry loop when the timer is concurrently expired. On
-non-RT kernels this just spin-waits until the timer callback has completed,
-except for posix CPU timers which have HAVE_POSIX_CPU_TIMERS_TASK_WORK
-enabled.

-In that case and on RT kernels the existing task could live lock when
-preempting the task which does the timer delivery.
-
-Replace spin_unlock() with an invocation of timer_wait_running() to handle
-it the same way as the other retry loops in the posix timer code.

-Subject: powercap: RAPL: Fix CONFIG_IOSF_MBI dependency
-
-From: Zhang Rui <rui.zhang@intel.com>
-
-[ Upstream commit 4658fe81b3f8afe8adf37734ec5fe595d90415c6 ]
-
-After commit 3382388d7148 ("intel_rapl: abstract RAPL common code"),
-accessing to IOSF_MBI interface is done in the RAPL common code.
-
-Thus it is the CONFIG_INTEL_RAPL_CORE that has dependency of
-CONFIG_IOSF_MBI, while CONFIG_INTEL_RAPL_MSR does not.
-
-This problem was not exposed previously because all the previous RAPL
-common code users, aka, the RAPL MSR and MMIO I/F drivers, have
-CONFIG_IOSF_MBI selected.
-
-Fix the CONFIG_IOSF_MBI dependency in RAPL code. This also fixes a build
-time failure when the RAPL TPMI I/F driver is introduced without
-selecting CONFIG_IOSF_MBI.
-
-x86_64-linux-ld: vmlinux.o: in function `set_floor_freq_atom':
-intel_rapl_common.c:(.text+0x2dac9b8): undefined reference to `iosf_mbi_write'
-x86_64-linux-ld: intel_rapl_common.c:(.text+0x2daca66): undefined reference to `iosf_mbi_read'
-
-Reference to iosf_mbi.h is also removed from the RAPL MSR I/F driver.

-
-From: Sumeet Pawnikar <sumeet.r.pawnikar@intel.com>
-
-[ Upstream commit d05b5e0baf424c8c4b4709ac11f66ab726c8deaf ]
-
-The current initialization of the struct x86_cpu_id via
-pl4_support_ids[] is partial and wrong. It is initializing
-"stepping" field with "X86_FEATURE_ANY" instead of "feature" field.
-
-Use X86_MATCH_INTEL_FAM6_MODEL macro instead of initializing
-each field of the struct x86_cpu_id for pl4_supported list of CPUs.
-This X86_MATCH_INTEL_FAM6_MODEL macro internally uses another macro
-X86_MATCH_VENDOR_FAM_MODEL_FEATURE for X86 based CPU matching with
-appropriate initialized values.

-A disassembly of interrupt_exit_kernel_prepare() shows a useless read

- c000e0f4: 71 29 80 00 andi. r9,r9,32768
-
-This is due to the use of local_irq_save(). The flags read by

-Subject: powerpc/powernv/sriov: perform null check on iov before dereferencing

-
-From: Colin Ian King <colin.i.king@gmail.com>
-
-[ Upstream commit f4f913c980bc6abe0ccfe88fe3909c125afe4a2d ]
-
-Currently pointer iov is being dereferenced before the null check of iov
-which can lead to null pointer dereference errors. Fix this by moving the
-iov null check before the dereferencing.
-
-Detected using cppcheck static analysis:

-Subject: powerpc/signal32: Force inlining of __unsafe_save_user_regs() and
- save_tm_user_regs_unsafe()
-
-From: Christophe Leroy <christophe.leroy@csgroup.eu>
-
-[ Upstream commit a03b1a0b19398a47489fdcef02ec19c2ba05a15d ]
-
-Looking at generated code for handle_signal32() shows calls to a
-function called __unsafe_save_user_regs.constprop.0 while user access
-is open.
-
-And that __unsafe_save_user_regs.constprop.0 function has two nops at
-the begining, allowing it to be traced, which is unexpected during
-user access open window.
-
-The solution could be to mark __unsafe_save_user_regs() no trace, but
-to be on the safe side the most efficient is to flag it __always_inline
-as already done for function __unsafe_restore_general_regs(). The
-function is relatively small and only called twice, so the size
-increase will remain in the noise.
-
-Do the same with save_tm_user_regs_unsafe() as it may suffer the
-same issue.

-Subject: powerpc: update ppc_save_regs to save current r1 in pt_regs
-
-From: Aditya Gupta <adityag@linux.ibm.com>
-
-[ Upstream commit b684c09f09e7a6af3794d4233ef785819e72db79 ]
-
-ppc_save_regs() skips one stack frame while saving the CPU register states.
-Instead of saving current R1, it pulls the previous stack frame pointer.
-
-When vmcores caused by direct panic call (such as `echo c >
-/proc/sysrq-trigger`), are debugged with gdb, gdb fails to show the
-backtrace correctly. On further analysis, it was found that it was because
-of mismatch between r1 and NIP.
-
-GDB uses NIP to get current function symbol and uses corresponding debug
-info of that function to unwind previous frames, but due to the
-mismatching r1 and NIP, the unwinding does not work, and it fails to
-unwind to the 2nd frame and hence does not show the backtrace.
-
-GDB backtrace with vmcore of kernel without this patch:
-
----------
-(gdb) bt
- #0 0xc0000000002a53e8 in crash_setup_regs (oldregs=<optimized out>,
- newregs=0xc000000004f8f8d8) at ./arch/powerpc/include/asm/kexec.h:69

- #2 0x0000000000000063 in ?? ()
- #3 0xc000000003579320 in ?? ()
----------
-
-Further analysis revealed that the mismatch occurred because
-"ppc_save_regs" was saving the previous stack's SP instead of the current
-r1. This patch fixes this by storing current r1 in the saved pt_regs.
-
-GDB backtrace with vmcore of patched kernel:

---------
-
-Nick adds:
- So this now saves regs as though it was an interrupt taken in the
- caller, at the instruction after the call to ppc_save_regs, whereas
- previously the NIP was there, but R1 came from the caller's caller and
- that mismatch is what causes gdb's dwarf unwinder to go haywire.

-
-From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
-
-[ Upstream commit 20c3dffdccbd494e0dd631d1660aeecbff6775f2 ]
-
-Several calls to ci_dpm_fini() will attempt to free resources that
-either have been freed before or haven't been allocated yet. This
-may lead to undefined or dangerous behaviour.
-
-For instance, if r600_parse_extended_power_table() fails, it might
-call r600_free_extended_power_table() as will ci_dpm_fini() later
-during error handling.
-
-Fix this by only freeing pointers to objects previously allocated.

-Subject: rcu: Make rcu_cpu_starting() rely on interrupts being disabled
-
-From: Paul E. McKenney <paulmck@kernel.org>
-
-[ Upstream commit 15d44dfa40305da1648de4bf001e91cc63148725 ]
-
-Currently, rcu_cpu_starting() is written so that it might be invoked
-with interrupts enabled. However, it is always called when interrupts
-are disabled, either by rcu_init(), notify_cpu_starting(), or from a
-call point prior to the call to notify_cpu_starting().
-
-But why bother requiring that interrupts be disabled? The purpose is
-to allow the rcu_data structure's ->beenonline flag to be set after all
-early processing has completed for the incoming CPU, thus allowing this
-flag to be used to determine when workqueues have been set up for the
-incoming CPU, while still allowing this flag to be used as a diagnostic
-within rcu_core().
-
-This commit therefore makes rcu_cpu_starting() rely on interrupts being
-disabled.

-
-[ Upstream commit bf5ddd736509a7d9077c0b6793e6f0852214dbea ]
-
-This code-movement-only commit moves the rcu_scale_cleanup() and
-rcu_scale_shutdown() functions to follow kfree_scale_cleanup().
-This is code movement is in preparation for a bug-fix patch that invokes
-kfree_scale_cleanup() from rcu_scale_cleanup().

-Subject: rcu-tasks: Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs
-
-From: Paul E. McKenney <paulmck@kernel.org>
-
-[ Upstream commit 401b0de3ae4fa49d1014c8941e26d9a25f37e7cf ]
-
-The rcu_tasks_invoke_cbs() function relies on queue_work_on() to silently
-fall back to WORK_CPU_UNBOUND when the specified CPU is offline. However,
-the queue_work_on() function's silent fallback mechanism relies on that
-CPU having been online at some time in the past. When queue_work_on()
-is passed a CPU that has never been online, workqueue lockups ensue,
-which can be bad for your kernel's general health and well-being.
-
-This commit therefore checks whether a given CPU has ever been online,
-and, if not substitutes WORK_CPU_UNBOUND in the subsequent call to
-queue_work_on(). Why not simply omit the queue_work_on() call entirely?
-Because this function is flooding callback-invocation notifications
-to all CPUs, and must deal with possibilities that include a sparse
-cpu_possible_mask.
-
-This commit also moves the setting of the rcu_data structure's
-->beenonline field to rcu_cpu_starting(), which executes on the
-incoming CPU before that CPU has ever enabled interrupts. This ensures
-that the required workqueues are present. In addition, because the
-incoming CPU has not yet enabled its interrupts, there cannot yet have
-been any softirq handlers running on this CPU, which means that the
-WARN_ON_ONCE(!rdp->beenonline) within the RCU_SOFTIRQ handler cannot
-have triggered yet.
-
-Fixes: d363f833c6d88 ("rcu-tasks: Use workqueues for multiple rcu_tasks_invoke_cbs() invocations")

-Subject: RDMA/bnxt_re: Avoid calling wake_up threads from spin_lock context

-[ Upstream commit 3099bcdc19b701f732f638ee45679858c08559bb ]
-
-bnxt_qplib_service_creq can be called from interrupt or tasklet or
-process context. So the function take irq variant of spin_lock.
-But when wake_up is invoked with the lock held, it is putting the

-Subject: RDMA/bnxt_re: Disable/kill tasklet only if it is enabled
-
-From: Selvin Xavier <selvin.xavier@broadcom.com>
-
-[ Upstream commit ab112ee7899d6171da5acd77a7ed7ae103f488de ]
-
-When the ulp hook to start the IRQ fails because the rings are not
-available, tasklets are not enabled. In this case when the driver is
-unloaded, driver calls CREQ tasklet_kill. This causes an indefinite hang
-as the tasklet is not enabled.
-
-Driver shouldn't call tasklet_kill if it is not enabled. So using the
-creq->requested and nq->requested flags to identify if both tasklets/irqs
-are registered. Checking this flag while scheduling the tasklet from
-ISR. Also, added a cleanup for disabling tasklet, in case request_irq
-fails during start_irq.
-
-Check for return value for bnxt_qplib_rcfw_start_irq and in case the
-bnxt_qplib_rcfw_start_irq fails, return bnxt_re_start_irq without
-attempting to start NQ IRQs.

-This could make the scenarios worse where one want to pin IRQs of a device
-port to certain CPUs.
-
-Fixed the code to use unique names which has PCI BDF information while
-registering interrupts like: "bnxt_re-nq-0@pci:0000:65:00.0" and
-"bnxt_re-creq@pci:0000:65:00.1".

-Subject: RDMA/bnxt_re: wraparound mbox producer index
-
-From: Kashyap Desai <kashyap.desai@broadcom.com>
-
-[ Upstream commit 0af91306e17ef3d18e5f100aa58aa787869118af ]
-
-Driver is not handling the wraparound of the mbox producer index correctly.
-Currently the wraparound happens once u32 max is reached.
-
-Bit 31 of the producer index register is special and should be set
-only once for the first command. Because the producer index overflow
-setting bit31 after a long time, FW goes to initialization sequence
-and this causes FW hang.
-
-Fix is to wraparound the mbox producer index once it reaches u16 max.

-
-The problem here isthat the inner array only has four 8-byte elements, so

-Subject: regulator: core: Streamline debugfs operations
-
-From: Geert Uytterhoeven <geert+renesas@glider.be>
-
-[ Upstream commit 08880713ceec023dd94d634f1e8902728c385939 ]
-
-If CONFIG_DEBUG_FS is not set:
-
- regulator: Failed to create debugfs directory
- ...
- regulator-dummy: Failed to create debugfs directory
-
-As per the comments for debugfs_create_dir(), errors returned by this
-function should be expected, and ignored:
-
- * If debugfs is not enabled in the kernel, the value -%ENODEV will be
- * returned.
- *
- * NOTE: it's expected that most callers should _ignore_ the errors returned
- * by this function. Other debugfs functions handle the fact that the "dentry"
- * passed to them could be an error and they don't crash in that case.
- * Drivers should generally work fine even if debugfs fails to init anyway.
-
-Adhere to the debugfs spirit, and streamline all operations by:
- 1. Demoting the importance of the printed error messages to debug
- level, like is already done in create_regulator(),
- 2. Further ignoring any returned errors, as by design, all debugfs
- functions are no-ops when passed an error pointer.

-
-[ Upstream commit 1b9e86d445a0f5c6d8dcbaf11508cb5dfb5848a8 ]
-
-If the probe routine fails with -EPROBE_DEFER after taking over the
-OF node from its parent driver, reprobing triggers pinctrl_bind_pins()
-and that will fail. Fix this by setting of_node_reused, so that the
-device does not try to setup pin muxing.
-
-For me this always happens once the driver is marked to prefer async
-probing and never happens without that flag.

-
-From: Song Shuai <songshuaishuai@tinylab.org>
-
-[ Upstream commit 91afbaafd6b1f1846520efd2b158066a25a1a316 ]
-
-During hibernation or restoration, freeze_secondary_cpus
-checks num_online_cpus via BUG_ON, and the subsequent
-save_processor_state also does the checking with WARN_ON.
-
-In the case of CONFIG_PM_SLEEP_SMP=n, freeze_secondary_cpus
-is not defined, but the sole possible condition to disable
-CONFIG_PM_SLEEP_SMP is !SMP where num_online_cpus is always 1.
-We also don't have to check it in save_processor_state.
-
-So remove the unnecessary checking in save_processor_state.

-Subject: rtnetlink: extend RTEXT_FILTER_SKIP_STATS to IFLA_VF_INFO
-
-From: Edwin Peer <edwin.peer@broadcom.com>
-
-[ Upstream commit fa0e21fa44438a0e856d42224bfa24641d37b979 ]
-
-This filter already exists for excluding IPv6 SNMP stats. Extend its
-definition to also exclude IFLA_VF_INFO stats in RTM_GETLINK.
-
-This patch constitutes a partial fix for a netlink attribute nesting
-overflow bug in IFLA_VFINFO_LIST. By excluding the stats when the
-requester doesn't need them, the truncation of the VF list is avoided.
-
-While it was technically only the stats added in commit c5a9f6f0ab40
-("net/core: Add drop counters to VF statistics") breaking the camel's
-back, the appreciable size of the stats data should never have been
-included without due consideration for the maximum number of VFs
-supported by PCI.

-Subject: s390/kasan: fix insecure W+X mapping warning
-
-From: Alexander Gordeev <agordeev@linux.ibm.com>
-
-[ Upstream commit 2ed8b509753a0454b52b2d72e982265472c8d861 ]
-
-Since commit 3b5c3f000c2e ("s390/kasan: move shadow mapping
-to decompressor") the decompressor establishes mappings for
-the shadow memory and sets initial protection attributes to
-RWX. The decompressed kernel resets protection to RW+NX
-later on.
-
-In case a shadow memory range is not aligned on page boundary
-(e.g. as result of mem= kernel command line parameter use),
-the "Checked W+X mappings: FAILED, 1 W+X pages found" warning
-hits.

-XDP layer will not necessary have access to the 4-bytes FCS checksum.

-Subject: sch_netem: fix issues in netem_change() vs get_dist_table()
-
-From: Eric Dumazet <edumazet@google.com>
-
-[ Upstream commit 11b73313c12403f617b47752db0ab3deef201af7 ]
-
-In blamed commit, I missed that get_dist_table() was allocating
-memory using GFP_KERNEL, and acquiring qdisc lock to perform
-the swap of newly allocated table with current one.
-
-In this patch, get_dist_table() is allocating memory and
-copy user data before we acquire the qdisc lock.
-
-Then we perform swap operations while being protected by the lock.
-
-Note that after this patch netem_change() no longer can do partial changes.
-If an error is returned, qdisc conf is left unchanged.

-
-From: Hao Jia <jiahao.os@bytedance.com>
-
-[ Upstream commit ebb83d84e49b54369b0db67136a5fe1087124dcc ]
-
-After commit 8ad075c2eb1f ("sched: Async unthrottling for cfs
-bandwidth"), we may update the rq clock multiple times in the loop of
-__cfsb_csd_unthrottle().
-
-A prior (although less common) instance of this problem exists in
-unthrottle_offline_cfs_rqs().
-
-Cure both by ensuring update_rq_clock() is called before the loop and
-setting RQCF_ACT_SKIP during the loop, to supress further updates.
-The alternative would be pulling update_rq_clock() out of
-unthrottle_cfs_rq(), but that gives an even bigger mess.

-
-From: Pierre-Clément Tosi <ptosi@google.com>
-
-[ Upstream commit ec336aa83162fe0f3d554baed2d4e2589b69ec6e ]
-
-The backslash characters escaping '$' in the command to sed (intended to
-prevent it from interpreting '$' as "end-of-line") are currently being
-consumed by the Shell (where they mean that sh should not evaluate what
-follows '$' as a variable name). This means that
-
- sed -e "/ \$/d"
-
-executes the script
-
- / $/d
-
-instead of the intended
-
- / \$/d
-
-So escape twice in mksysmap any '$' that actually needs to reach sed
-escaped so that the backslash survives the Shell.

-Subject: scsi: lpfc: Revise NPIV ELS unsol rcv cmpl logic to drop ndlp based
- on nlp_state
-
-From: Justin Tee <justin.tee@broadcom.com>
-
-[ Upstream commit 9914a3d033d3e1d836a43e93e9738e7dd44a096a ]
-
-When NPIV ports are zoned to devices that support both initiator and target
-mode, a remote device's initiated PRLI results in unintended final kref
-clean up of the device's ndlp structure. This disrupts NPIV ports'
-discovery for target devices that support both initiator and target mode.
-
-Modify the NPIV lpfc_drop_node clause such that we allow the ndlp to live
-so long as it was in NLP_STE_PLOGI_ISSUE, NLP_STE_REG_LOGIN_ISSUE, or
-NLP_STE_PRLI_ISSUE nlp_state. This allows lpfc's issued PRLI completion
-routine to determine if the final kref clean up should execute rather than
-a remote device's issued PRLI.

-
-[ Upstream commit 549e91a9bbaa0ee480f59357868421a61d369770 ]
-
-ufshcd_queuecommand() may be called two times in a row for a SCSI command
-before it is completed. Hence make the following changes:
-
- - In the functions that submit a command, do not check the old value of

-
- - In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.
-
-See also scsi_send_eh_cmnd().
-
-This commit prevents that the following appears if a command times out:

-
-From: Bart Van Assche <bvanassche@acm.org>
-
-[ Upstream commit fe8637f7708c16765ecf4035813efbfdd2c9be10 ]
-
-One UFS vendor asked to increase the UFS timeout from 1 s to 3 s. Another
-UFS vendor asked to increase the UFS timeout from 1 s to 10 s. Hence this
-patch that increases the UFS timeout to 10 s. This patch can cause the
-total timeout to exceed 20 s, the Android shutdown timeout. This is fine
-since the loop around ufshcd_execute_start_stop() exists to deal with unit
-attentions and because unit attentions are reported quickly.

-Subject: scsi: ufs: core: mcq: Fix the incorrect OCS value for the device
- command
-
-From: Stanley Chu <stanley.chu@mediatek.com>
-
-[ Upstream commit 0fef6bb730c490fcdc4347dbd21646d3ffe62cf5 ]
-
-In MCQ mode, when a device command uses a hardware queue shared with other
-commands, a race condition may occur in the following scenario:
-
- 1. A device command is completed in CQx with CQE entry "e".
-
- 2. The interrupt handler copies the "cqe" pointer to "hba->dev_cmd.cqe"
- and completes "hba->dev_cmd.complete".
-
- 3. The "ufshcd_wait_for_dev_cmd()" function is awakened and retrieves the
- OCS value from "hba->dev_cmd.cqe".
-
-However, there is a possibility that the CQE entry "e" will be overwritten
-by newly completed commands in CQx, resulting in an incorrect OCS value
-being received by "ufshcd_wait_for_dev_cmd()".
-
-To avoid this race condition, the OCS value should be immediately copied to
-the struct "lrb" of the device command. Then "ufshcd_wait_for_dev_cmd()"
-can retrieve the OCS value from the struct "lrb".

-Subject: sctp: add bpf_bypass_getsockopt proto callback
-
-From: Alexander Mikhalitsyn <aleksandr.mikhalitsyn@canonical.com>
-
-[ Upstream commit 2598619e012cee5273a2821441b9a051ad931249 ]
-
-Implement ->bpf_bypass_getsockopt proto callback and filter out
-SCTP_SOCKOPT_PEELOFF, SCTP_SOCKOPT_PEELOFF_FLAGS and SCTP_SOCKOPT_CONNECTX3
-socket options from running eBPF hook on them.
-
-SCTP_SOCKOPT_PEELOFF and SCTP_SOCKOPT_PEELOFF_FLAGS options do fd_install(),
-and if BPF_CGROUP_RUN_PROG_GETSOCKOPT hook returns an error after success of
-the original handler sctp_getsockopt(...), userspace will receive an error
-from getsockopt syscall and will be not aware that fd was successfully
-installed into a fdtable.
-
-As pointed by Marcelo Ricardo Leitner it seems reasonable to skip
-bpf getsockopt hook for SCTP_SOCKOPT_CONNECTX3 sockopt too.
-Because internaly, it triggers connect() and if error is masked
-then userspace will be confused.
-
-This patch was born as a result of discussion around a new SCM_PIDFD interface:
-https://lore.kernel.org/all/20230413133355.350571-3-aleksandr.mikhalitsyn@canonical.com/

-Subject: selftests/bpf: Do not use sign-file as testcase
-
-From: Alexey Gladkov <legion@kernel.org>
-
-[ Upstream commit f04a32b2c5b539e3c097cb5c7c1df12a8f4a0cf0 ]
-
-The sign-file utility (from scripts/) is used in prog_tests/verify_pkcs7_sig.c,
-but the utility should not be called as a test. Executing this utility produces
-the following error:
-
- selftests: /linux/tools/testing/selftests/bpf: urandom_read
- ok 16 selftests: /linux/tools/testing/selftests/bpf: urandom_read
-
- selftests: /linux/tools/testing/selftests/bpf: sign-file
- not ok 17 selftests: /linux/tools/testing/selftests/bpf: sign-file # exit=2
-
-Also, urandom_read is mistakenly used as a test. It does not lead to an error,
-but should be moved over to TEST_GEN_FILES as well. The empty TEST_CUSTOM_PROGS
-can then be removed.

-From: Haifeng Xu <haifeng.xu@shopee.com>
-
-[ Upstream commit 19ab365762c6cc39dfdee9e13ab0d12fe4b5540d ]
-
-Since commit f079a020ba95 ("selftests: memcg: factor out common parts of
-memory.{low,min} tests"), the value used in second alloc_anon has changed
-from 148M to 170M. Because memory.low allows reclaiming page cache in
-child cgroups, so the memory.current is close to 30M instead of 50M.
-Therefore, adjust the expected value of parent cgroup.

-Subject: sfc: fix crash when reading stats while NIC is resetting
-
-From: Edward Cree <ecree.xilinx@gmail.com>
-
-[ Upstream commit d1b355438b8325a486f087e506d412c4e852f37b ]
-
-efx_net_stats() (.ndo_get_stats64) can be called during an ethtool
- selftest, during which time nic_data->mc_stats is NULL as the NIC has
- been fini'd. In this case do not attempt to fetch the latest stats
- from the hardware, else we will crash on a NULL dereference:
- BUG: kernel NULL pointer dereference, address: 0000000000000038
- RIP efx_nic_update_stats
- abridged calltrace:
- efx_ef10_update_stats_pf
- efx_net_stats
- dev_get_stats
- dev_seq_printf_stats
-Skipping the read is safe, we will simply give out stale stats.
-To ensure that the free in efx_ef10_fini_nic() does not race against
- efx_ef10_update_stats_pf(), which could cause a TOCTTOU bug, take the
- efx->stats_lock in fini_nic (it is already held across update_stats).

-Subject: sfc: release encap match in efx_tc_flow_free()
-
-From: Edward Cree <ecree.xilinx@gmail.com>
-
-[ Upstream commit 28fa3ac487c6d30aaa10570481c27b6adfc492b3 ]
-
-When force-freeing leftover entries from our match_action_ht, call
- efx_tc_delete_rule(), which releases all the rule's resources, rather
- than open-coding it. The open-coded version was missing a call to
- release the rule's encap match (if any).
-It probably doesn't matter as everything's being torn down anyway, but
- it's cleaner this way and prevents further error messages potentially
- being logged by efx_tc_encap_match_free() later on.
-Move efx_tc_flow_free() further down the file to avoid introducing a
- forward declaration of efx_tc_delete_rule().

-
-From: Paulo Alcantara <pc@manguebit.com>
-
-[ Upstream commit 3ae872de410751fe5e629e04da491a632d95201c ]
-
-When having two DFS root mounts that are connected to same namespace,
-same mount options but different prefix paths, we can't really use the
-shared @server->origin_fullpath when chasing DFS links in them.
-
-Move the origin_fullpath field to cifs_tcon structure so when having
-shared DFS root mounts with different prefix paths, and we need to
-chase any DFS links, dfs_get_automount_devname() will pick up the
-correct full path out of the @tcon that will be used for the new
-mount.
-
-Before patch
-
- mount.cifs //dom/dfs/dir /mnt/1 -o ...
- mount.cifs //dom/dfs /mnt/2 -o ...
- # shared server, ses, tcon
- # server: origin_fullpath=//dom/dfs/dir
-
- # @server->origin_fullpath + '/dir/link1'
- $ ls /mnt/2/dir/link1
- ls: cannot open directory '/mnt/2/dir/link1': No such file or directory
-
-After patch
-
- mount.cifs //dom/dfs/dir /mnt/1 -o ...
- mount.cifs //dom/dfs /mnt/2 -o ...
- # shared server & ses
- # tcon_1: origin_fullpath=//dom/dfs/dir
- # tcon_2: origin_fullpath=//dom/dfs
-
- # @tcon_2->origin_fullpath + '/dir/link1'
- $ ls /mnt/2/dir/link1
- dir0 dir1 dir10 dir3 dir5 dir6 dir7 dir9 target2_file.txt tsub

-Subject: soc/fsl/qe: fix usb.c build errors
-
-From: Randy Dunlap <rdunlap@infradead.org>
-
-[ Upstream commit 7b1a78babd0d2cd27aa07255dee0c2d7ac0f31e3 ]
-
-Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
-This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
-When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
-being set. When USB_FSL_QE is set, QE_USB deafults to y, which
-causes build errors when QUICC_ENGINE is not set. Making
-QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.
-
-Fixes these build errors:
-
-drivers/soc/fsl/qe/usb.o: in function `qe_usb_clock_set':
-usb.c:(.text+0x1e): undefined reference to `qe_immr'
-powerpc-linux-ld: usb.c:(.text+0x2a): undefined reference to `qe_immr'

-Subject: spi: dw: Round of n_bytes to power of 2
-
-From: Joy Chakraborty <joychakr@google.com>
-
-[ Upstream commit 9f34baf67e4d08908fd94ff29c825bb673295336 ]
-
-n_bytes variable in the driver represents the number of bytes per word
-that needs to be sent/copied to fifo. Bits/word can be between 8 and 32
-bits from the client but in memory they are a power of 2, same is mentioned
-in spi.h header:
-"
- * @bits_per_word: Data transfers involve one or more words; word sizes
- * like eight or 12 bits are common. In-memory wordsizes are
- * powers of two bytes (e.g. 20 bit samples use 32 bits).
- * This may be changed by the device's driver, or left at the
- * default (0) indicating protocol words are eight bit bytes.
- * The spi_transfer.bits_per_word can override this for each transfer.
-"
-
-Hence, round of n_bytes to a power of 2 to avoid values like 3 which
-would generate unalligned/odd accesses to memory/fifo.
-
-* tested on Baikal-T1 based system with DW SPI-looped back interface
-transferring a chunk of data with DFS:8,12,16.

-

-
-[ Upstream commit 5fd7c99ecf45c8ee8a9b1268f0ffc91cc6271da2 ]
-
-The CS_TOGGLE bit when set is supposed to instruct FW to
-toggle CS line between words. The driver with intent of
-disabling this behaviour has been unsetting BIT(0). This has
-not caused any trouble so far because the original BIT(1)
-is untouched and BIT(0) likely wasn't being used.

-From: Vijaya Krishna Nivarthi <quic_vnivarth@quicinc.com>
-
-[ Upstream commit 3a76c7ca9e77269dd10cf21465a055274cfa40c6 ]
-
-The spi geni driver in SE DMA mode, unlike GSI DMA, is not making use of
-DMA mapping functionality available in the framework.
-The driver does mapping internally which makes dma buffer fields available
-in spi_transfer struct superfluous while requiring additional members in
-spi_geni_master struct.
-
-Conform to the design by having framework handle map/unmap and do only
-DMA transfer in the driver; this also simplifies code a bit.
-

-Subject: thermal/drivers/qcom/tsens-v0_1: Add mdm9607 correction offsets
-
-From: Stephan Gerhold <stephan.gerhold@kernkonzept.com>
-
-[ Upstream commit b6f739da0070c36655118618a173a59fa14c7adc ]
-
-According to the msm-3.18 vendor kernel from Qualcomm, mdm9607 needs
-"correction factors" to adjust for additional offsets observed after the
-factory calibration values in the fuses [1, 2].
-
-The fixed offsets should be applied unless there is a special
-calibration mode value that indicates that no offsets are needed [3].
-
-Note that the new calibration mode values are called differently in this
-patch compared to the vendor kernel:
- - TSENS_TWO_POINT_CALIB_N_WA -> ONE_PT_CALIB2_NO_OFFSET
- - TSENS_TWO_POINT_CALIB_N_OFFSET_WA -> TWO_PT_CALIB_NO_OFFSET
-This is because close inspection of the calibration function [3] reveals
-that TSENS_TWO_POINT_CALIB_N_WA is actually a "one point" calibration
-because the if statements skip all "point2" related code for it.

-There are MAX 16 sensors, but not all of them supported. Such as

-Subject: thermal/drivers/sun8i: Fix some error handling paths in
- sun8i_ths_probe()
-
-From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
-
-[ Upstream commit 89382022b370dfd34eaae9c863baa123fcd4d132 ]
-
-Should an error occur after calling sun8i_ths_resource_init() in the probe
-function, some resources need to be released, as already done in the
-.remove() function.
-
-Switch to the devm_clk_get_enabled() helper and add a new devm_action to
-turn sun8i_ths_resource_init() into a fully managed function.
-
-Move the place where reset_control_deassert() is called so that the
-recommended order of reset release/clock enable steps is kept.
-A64 manual states that:
-
- 3.3.6.4. Gating and reset
-
- Make sure that the reset signal has been released before the release of
- module clock gating;
-
-This fixes the issue and removes some LoC at the same time.

-Subject: tools/resolve_btfids: Fix setting HOSTCFLAGS
-
-From: Viktor Malik <vmalik@redhat.com>
-
-[ Upstream commit edd75c802855271c8610f58a2fc9e54aefc49ce5 ]
-
-Building BPF selftests with custom HOSTCFLAGS yields an error:
-
- # make HOSTCFLAGS="-O2"
- [...]
- HOSTCC ./tools/testing/selftests/bpf/tools/build/resolve_btfids/main.o
- main.c:73:10: fatal error: linux/rbtree.h: No such file or directory
- 73 | #include <linux/rbtree.h>
- | ^~~~~~~~~~~~~~~~
-
-The reason is that tools/bpf/resolve_btfids/Makefile passes header
-include paths by extending HOSTCFLAGS which is overridden by setting
-HOSTCFLAGS in the make command (because of Makefile rules [1]).
-
-This patch fixes the above problem by passing the include paths via
-`HOSTCFLAGS_resolve_btfids` which is used by tools/build/Build.include
-and can be combined with overridding HOSTCFLAGS.

-Subject: vfio/mdev: Move the compat_class initialization to module init
-
-From: Eric Farman <farman@linux.ibm.com>
-
-[ Upstream commit ff598081e5b9d0bdd6874bfe340811bbb75b35e4 ]
-
-The pointer to mdev_bus_compat_class is statically defined at the top
-of mdev_core, and was originally (commit 7b96953bc640 ("vfio: Mediated
-device Core driver") serialized by the parent_list_lock. The blamed
-commit removed this mutex, leaving the pointer initialization
-unserialized. As a result, the creation of multiple MDEVs in parallel
-(such as during boot) can encounter errors during the creation of the
-sysfs entries, such as:

-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit 9ec272c586b07d1abf73438524bd12b1df9c5f9b ]
-
-Patch series "watchdog: Cleanup / fixes after buddy series v5 reviews".
-
-This patch series attempts to finish resolving the feedback received
-from Petr Mladek on the v5 series I posted.
-
-Probably the only thing that wasn't fully as clean as Petr requested was
-the Kconfig stuff. I couldn't find a better way to express it without a
-more major overhaul. In the very least, I renamed "NON_ARCH" to
-"PERF_OR_BUDDY" in the hopes that will make it marginally better.
-
-Nothing in this series is terribly critical and even the bugfixes are
-small. However, it does cleanup a few things that were pointed out in
-review.
-
-This patch (of 10):
-
-The permissions for the kernel.nmi_watchdog sysctl have always been set at
-compile time despite the fact that a watchdog can fail to probe. Let's
-fix this and set the permissions based on whether the hardlockup detector
-actually probed.

-Subject: watchdog/hardlockup: move perf hardlockup checking/panic to common
- watchdog.c
-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit 81972551df9d168a8183b786ff4de06008469c2e ]
-
-The perf hardlockup detector works by looking at interrupt counts and
-seeing if they change from run to run. The interrupt counts are managed
-by the common watchdog code via its watchdog_timer_fn().
-
-Currently the API between the perf detector and the common code is a
-function: is_hardlockup(). When the hard lockup detector sees that
-function return true then it handles printing out debug info and inducing
-a panic if necessary.
-
-Let's change the API a little bit in preparation for the buddy hardlockup
-detector. The buddy hardlockup detector wants to print nearly the same
-debug info and have nearly the same panic behavior. That means we want to
-move all that code to the common file. For now, the code in the common
-file will only be there if the perf hardlockup detector is enabled, but
-eventually it will be selected by a common config.
-
-Right now, this _just_ moves the code from the perf detector file to the
-common file and changes the names. It doesn't make the changes that the
-buddy hardlockup detector will need and doesn't do any style cleanups. A
-future patch will do cleanup to make it more obvious what changed.
-
-With the above, we no longer have any callers of is_hardlockup() outside
-of the "watchdog.c" file, so we can remove it from the header, make it
-static, and move it to the same "#ifdef" block as our new
-watchdog_hardlockup_check(). While doing this, it can be noted that even
-if no hardlockup detectors were configured the existing code used to still
-have the code for counting/checking "hrtimer_interrupts" even if the perf
-hardlockup detector wasn't configured. We didn't need to do that, so move
-all the "hrtimer_interrupts" counting to only be there if the perf
-hardlockup detector is configured as well.
-
-This change is expected to be a no-op.

-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit df95d3085caa5b99a60eb033d7ad6c2ff2b43dbf ]
-
-Do a search and replace of:
-- NMI_WATCHDOG_ENABLED => WATCHDOG_HARDLOCKUP_ENABLED
-- SOFT_WATCHDOG_ENABLED => WATCHDOG_SOFTOCKUP_ENABLED
-- watchdog_nmi_ => watchdog_hardlockup_
-- nmi_watchdog_available => watchdog_hardlockup_available

-- soft_watchdog_user_enabled => watchdog_softlockup_user_enabled
-- NMI_WATCHDOG_DEFAULT => WATCHDOG_HARDLOCKUP_DEFAULT
-
-Then update a few comments near where names were changed.
-
-This is specifically to make it less confusing when we want to introduce
-the buddy hardlockup detector, which isn't using NMIs. As part of this,
-we sanitized a few names for consistency.

-Subject: watchdog/perf: adapt the watchdog_perf interface for async model
-
-From: Lecopzer Chen <lecopzer.chen@mediatek.com>
-
-[ Upstream commit 930d8f8dbab97cb05dba30e67a2dfa0c6dbf4bc7 ]
-
-When lockup_detector_init()->watchdog_hardlockup_probe(), PMU may be not
-ready yet. E.g. on arm64, PMU is not ready until
-device_initcall(armv8_pmu_driver_init). And it is deeply integrated with
-the driver model and cpuhp. Hence it is hard to push this initialization
-before smp_init().
-
-But it is easy to take an opposite approach and try to initialize the
-watchdog once again later. The delayed probe is called using workqueues.
-It need to allocate memory and must be proceed in a normal context. The
-delayed probe is able to use if watchdog_hardlockup_probe() returns
-non-zero which means the return code returned when PMU is not ready yet.
-
-Provide an API - lockup_detector_retry_init() for anyone who needs to
-delayed init lockup detector if they had ever failed at
-lockup_detector_init().
-
-The original assumption is: nobody should use delayed probe after
-lockup_detector_check() which has __init attribute. That is, anyone uses
-this API must call between lockup_detector_init() and
-lockup_detector_check(), and the caller must have __init attribute

-Subject: watchdog/perf: define dummy watchdog_update_hrtimer_threshold() on
- correct config
-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit 5e008df11c55228a86a1bae692cc2002503572c9 ]
-
-Patch series "watchdog/hardlockup: Add the buddy hardlockup detector", v5.
-
-This patch series adds the "buddy" hardlockup detector. In brief, the
-buddy hardlockup detector can detect hardlockups without arch-level
-support by having CPUs checkup on a "buddy" CPU periodically.
-
-Given the new design of this patch series, testing all combinations is
-fairly difficult. I've attempted to make sure that all combinations of
-CONFIG_ options are good, but it wouldn't surprise me if I missed
-something. I apologize in advance and I'll do my best to fix any
-problems that are found.
-
-This patch (of 18):
-
-The real watchdog_update_hrtimer_threshold() is defined in
-kernel/watchdog_hld.c. That file is included if
-CONFIG_HARDLOCKUP_DETECTOR_PERF and the function is defined in that file
-if CONFIG_HARDLOCKUP_CHECK_TIMESTAMP.
-
-The dummy version of the function in "nmi.h" didn't get that quite right.
-While this doesn't appear to be a huge deal, it's nice to make it
-consistent.
-
-It doesn't break builds because CHECK_TIMESTAMP is only defined by x86 so
-others don't get a double definition, and x86 uses perf lockup detector,
-so it gets the out of line version.

-Subject: watchdog/perf: more properly prevent false positives with turbo modes
-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit 4379e59fe5665cfda737e45b8bf2f05321ef049c ]
-
-Currently, in the watchdog_overflow_callback() we first check to see if
-the watchdog had been touched and _then_ we handle the workaround for
-turbo mode. This order should be reversed.
-
-Specifically, "touching" the hardlockup detector's watchdog should avoid
-lockups being detected for one period that should be roughly the same
-regardless of whether we're running turbo or not. That means that we
-should do the extra accounting for turbo _before_ we look at (and clear)
-the global indicating that we've been touched.
-
-NOTE: this fix is made based on code inspection. I am not aware of any
-reports where the old code would have generated false positives. That
-being said, this order seems more correct and also makes it easier down
-the line to share code with the "buddy" hardlockup detector.

-Subject: wifi: ath10k: Trigger STA disconnect after reconfig complete on
- hardware restart
-
-From: Youghandhar Chintala <quic_youghand@quicinc.com>
-
-[ Upstream commit 75bd32f5ce94bc365ba0b9b68bcf9de84a391d37 ]
-
-Currently, on WCN3990, the station disconnect after hardware recovery is
-not working as expected. This is because of setting the
-IEEE80211_SDATA_DISCONNECT_HW_RESTART flag very early in the hardware
-recovery process even before the driver invokes ieee80211_hw_restart().
-On the contrary, mac80211 expects this flag to be set after
-ieee80211_hw_restart() is invoked for it to trigger station disconnect.
-
-Set the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag in
-ath10k_reconfig_complete() instead to fix this.
-
-The other targets are not affected by this change, since the hardware
-params flag is not set.
-
-Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Fedor Pchelkin <pchelkin@ispras.ru>
-
-[ Upstream commit f24292e827088bba8de7158501ac25a59b064953 ]
-
-For the reasons also described in commit b383e8abed41 ("wifi: ath9k: avoid
-uninit memory read in ath9k_htc_rx_msg()"), ath9k_htc_rx_msg() should
-validate pkt_len before accessing the SKB.
-
-For example, the obtained SKB may have been badly constructed with
-pkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdr
-but after being processed in ath9k_htc_rx_msg() and passed to
-ath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI
-command header which should be located inside its data payload.
-
-Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit
-memory can be referenced.
-
-Tested on Qualcomm Atheros Communications AR9271 802.11n .
-
-Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

-
-On EDMA capable hardware, ath9k_txq_list_has_key() can enter infinite
-loop if it is called while all txq_fifos have packets that use different
-key that the one we are looking for. Fix it by exiting the loop if all
-txq_fifos have been checked already.
-
-Because this loop is called under spin_lock_bh() (see ath_txq_lock) it
-causes the following rcu stall:

-Subject: wifi: cfg80211: drop incorrect nontransmitted BSS update code
-
-From: Benjamin Berg <benjamin.berg@intel.com>
-
-[ Upstream commit 39432f8a3752a87a53fd8d5e51824a43aaae5cab ]
-
-The removed code ran for any BSS that was not included in the MBSSID
-element in order to update it. However, instead of using the correct
-inheritance rules, it would simply copy the elements from the
-transmitting AP. The result is that we would report incorrect elements
-in this case.
-
-After some discussions, it seems that there are likely not even APs
-actually using this feature. Either way, removing the code decreases
-complexity and makes the cfg80211 behaviour more correct.

-From: Johannes Berg <johannes.berg@intel.com>
-
-[ Upstream commit e8c2af660ba0790afd14d5cbc2fd05c6dc85e207 ]
-
-Since regulatory disconnect was added, OCB and NAN interface
-types were added, which made it completely unusable for any
-driver that allowed OCB/NAN. Add OCB/NAN (though NAN doesn't
-do anything, we don't have any info) and also remove all the
-logic that opts out, so it won't be broken again if/when new
-interface types are added.
-
-Fixes: 6e0bd6c35b02 ("cfg80211: 802.11p OCB mode handling")
-Fixes: cb3b7d87652a ("cfg80211: add start / stop NAN commands")

-Subject: wifi: cfg80211: rewrite merging of inherited elements
-
-From: Benjamin Berg <benjamin.berg@intel.com>
-
-[ Upstream commit dfd9aa3e7a456d57b18021d66472ab7ff8373ab7 ]
-
-The cfg80211_gen_new_ie function merges the IEs using inheritance rules.
-Rewrite this function to fix issues around inheritance rules. In
-particular, vendor elements do not require any special handling, as they
-are either all inherited or overridden by the subprofile.
-Also, add fragmentation handling as this may be needed in some cases.
-
-This also changes the function to not require making a copy. The new
-version could be optimized a bit by explicitly tracking which IEs have
-been handled already rather than looking that up again every time.
-
-Note that a small behavioural change is the removal of the SSID special
-handling. This should be fine for the MBSSID element, as the SSID must
-be included in the subelement.

-Subject: wifi: iwlwifi: mvm: check only affected links
-
-From: Johannes Berg <johannes.berg@intel.com>
-
-[ Upstream commit de1076008148460fe273e6d39158faffcc954991 ]
-
-When hostapd starts up, it may start up with only one link
-while the other is still scanning for overlapping BSSes. A
-station might start to connect at this point, but we run
-into this warning instead. Since there's no need to check
-for _all_ links, restrict the check to just the affected
-links that the STA will be using.

-Subject: wifi: iwlwifi: mvm: correctly access HE/EHT sband capa
-
-From: Johannes Berg <johannes.berg@intel.com>
-
-[ Upstream commit f912959875761084fda351e1257dcfa9d1fa3037 ]
-
-We can't just dereference the sband->iftype_data pointer,
-that's an array so we need to access the right entry. Use
-the previously introduced helper functions to do that.
-
-There are also cases, e.g. when loading with disable_11ax=1,
-where the pointer might be NULL but we still attempt to use
-it, causing a crash.

-From: Johannes Berg <johannes.berg@intel.com>
-
-[ Upstream commit 96fb6f47db24a712d650b0a9b9074873f273fb0e ]
-
-In mac80211, it's required that we pull from TXQs by calling
-ieee80211_tx_dequeue() only with softirqs disabled. However,
-in iwl_mvm_queue_state_change() we're often called with them
-enabled, e.g. from flush if anything was flushed, triggering
-a mac80211 warning.
-
-Fix that by disabling the softirqs across the TX call.

-
-From: Nicolas Cavallari <nicolas.cavallari@green-communications.fr>
-
-[ Upstream commit 6e21e7b8cd897193cee3c2649640efceb3004ba5 ]
-
-In mesh mode, ieee80211_chandef_he_6ghz_oper() is called by
-mesh_matches_local() for every received mesh beacon.
-
-On a 6 GHz mesh of a HE-only phy, this spams that the hardware does not
-have EHT capabilities, even if the received mesh beacon does not have an
-EHT element.
-
-Unlike HE, not supporting EHT in the 6 GHz band is not an error so do
-not print anything in this case.

-
-From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
-
-[ Upstream commit 4f8d66a9fb2edcd05c1e563456a55a08910bfb37 ]
-
-Should ray_config() fail, some resources need to be released as already
-done in the remove function.
-
-While at it, remove a useless and erroneous comment. The probe is
-ray_probe(), not ray_attach().

-Subject: wifi: rsi: Do not configure WoWlan in shutdown hook if not enabled
-
-From: Marek Vasut <marex@denx.de>
-
-[ Upstream commit b241e260820b68c09586e8a0ae0fc23c0e3215bd ]
-
-In case WoWlan was never configured during the operation of the system,
-the hw->wiphy->wowlan_config will be NULL. rsi_config_wowlan() checks
-whether wowlan_config is non-NULL and if it is not, then WARNs about it.
-The warning is valid, as during normal operation the rsi_config_wowlan()
-should only ever be called with non-NULL wowlan_config. In shutdown this
-rsi_config_wowlan() should only ever be called if WoWlan was configured
-before by the user.
-
-Add checks for non-NULL wowlan_config into the shutdown hook. While at it,
-check whether the wiphy is also non-NULL before accessing wowlan_config .
-Drop the single-use wowlan_config variable, just inline it into function
-call.

-Subject: wifi: rtw88: usb: silence log flooding error message
-
-From: Sascha Hauer <s.hauer@pengutronix.de>
-
-[ Upstream commit 1f1784a59caf3eefd127908a1a3cf224017ff9c7 ]
-
-When receiving more rx packets than the kernel can handle the driver
-drops the packets and issues an error message. This is bad for two
-reasons. The logs are flooded with myriads of messages, but then time
-consumed for printing messages in that critical code path brings down
-the device. After some time of excessive rx load the driver responds
-with:
-
-rtw_8822cu 1-1:1.2: failed to get tx report from firmware
-rtw_8822cu 1-1:1.2: firmware failed to report density after scan
-rtw_8822cu 1-1:1.2: firmware failed to report density after scan
-
-The device stops working until being replugged.
-
-Fix this by lowering the priority to debug level and also by
-ratelimiting it.

-Subject: x86/efi: Make efi_set_virtual_address_map IBT safe
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Thomas Gleixner <tglx@linutronix.de>
-
-[ Upstream commit 0303c9729afc4094ef53e552b7b8cff7436028d6 ]
-
-Niklāvs reported a boot regression on an Alderlake machine and bisected it
-to commit 9df9d2f0471b ("init: Invoke arch_cpu_finalize_init() earlier").
-
-By moving the invocation of arch_cpu_finalize_init() further down he
-identified that efi_enter_virtual_mode() is the function which causes the
-boot hang.
-
-The main difference of the earlier invocation is that the boot CPU is
-already fully initialized and mitigations and alternatives are applied.
-
-But the only really interesting change turned out to be IBT, which is now
-enabled before efi_enter_virtual_mode(). "ibt=off" on the kernel command
-line cured the problem.
-
-Inspection of the involved calls in efi_enter_virtual_mode() unearthed that
-efi_set_virtual_address_map() is the only place in the kernel which invokes
-an EFI call without the IBT safe wrapper. This went obviously unnoticed so
-far as IBT was enabled later.
-
-Use arch_efi_call_virt() instead of efi_call() to cure that.
-

-Subject: x86/hyperv: Set MTRR state when running as SEV-SNP Hyper-V guest
-
-From: Juergen Gross <jgross@suse.com>
-
-[ Upstream commit c957f1f3c498bcce85c04e92e60afbae1fd10cde ]
-
-In order to avoid mappings using the UC- cache attribute, set the
-MTRR state to use WB caching as the default.
-
-This is needed in order to cope with the fact that PAT is enabled,
-while MTRRs are not supported by the hypervisor.

-Subject: x86/mm: Fix __swp_entry_to_pte() for Xen PV guests
-
-From: Juergen Gross <jgross@suse.com>
-
-[ Upstream commit 0f88130e8a6fd185b0aeb5d8e286083735f2585a ]
-
-Normally __swp_entry_to_pte() is never called with a value translating
-to a valid PTE. The only known exception is pte_swap_tests(), resulting
-in a WARN splat in Xen PV guests, as __pte_to_swp_entry() did
-translate the PFN of the valid PTE to a guest local PFN, while
-__swp_entry_to_pte() doesn't do the opposite translation.
-
-Fix that by using __pte() in __swp_entry_to_pte() instead of open
-coding the native variant of it.
-
-For correctness do the similar conversion for __swp_entry_to_pmd().

-Subject: x86/mtrr: Remove physical address size calculation
-
-From: Juergen Gross <jgross@suse.com>
-
-[ Upstream commit f6b980646b93a8c585b4ed991b8a34e8fc6ef847 ]
-
-The physical address width calculation in mtrr_bp_init() can easily be
-replaced with using the already available value x86_phys_bits from
-struct cpuinfo_x86.
-
-The same information source can be used in mtrr/cleanup.c, removing the
-need to pass that value on to mtrr_cleanup().
-
-In print_mtrr_state() use x86_phys_bits instead of recalculating it
-from size_or_mask.
-
-Move setting of size_or_mask and size_and_mask into a dedicated new
-function in mtrr/generic.c, enabling to make those 2 variables static,
-as they are used in generic.c only now.

- [ bp:
- - Drop mtrr_set_mask()
- - Unbreak long lines
- - Move struct mtrr_state_type out of the uapi header as it doesn't

-Subject: x86/mtrr: Support setting MTRR state for software defined MTRRs
-
-From: Juergen Gross <jgross@suse.com>
-
-[ Upstream commit 29055dc74287467bd7a053d60b4afe753832960d ]
-
-When running virtualized, MTRR access can be reduced (e.g. in Xen PV
-guests or when running as a SEV-SNP guest under Hyper-V). Typically, the
-hypervisor will not advertize the MTRR feature in CPUID data, resulting
-in no MTRR memory type information being available for the kernel.
-
-This has turned out to result in problems (Link tags below):
-
-- Hyper-V SEV-SNP guests using uncached mappings where they shouldn't
-- Xen PV dom0 mapping memory as WB which should be UC- instead
-
-Solve those problems by allowing an MTRR static state override,
-overwriting the empty state used today. In case such a state has been
-set, don't call get_mtrr_state() in mtrr_bp_init().
-
-The set state will only be used by mtrr_type_lookup(), as in all other
-cases mtrr_enabled() is being checked, which will return false. Accept
-the overwrite call only for selected cases when running as a guest.
-Disable X86_FEATURE_MTRR in order to avoid any MTRR modifications by
-just refusing them.

-
-[ Upstream commit 2997d94b5dd0e8b10076f5e0b6f18410c73e28bd ]
-
-When writing a task id to the "tasks" file in an rdtgroup,
-rdtgroup_tasks_write() treats the pid as a number in the current pid
-namespace. But when reading the "tasks" file, rdtgroup_tasks_show() shows
-the list of global pids from the init namespace, which is confusing and
-incorrect.
-
-To be more robust, let the "tasks" file only show pids in the current pid
-namespace.

-Subject: x86/tdx: Fix race between set_memory_encrypted() and
- load_unaligned_zeropad()
-
-From: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
-
-[ Upstream commit 195edce08b63d293377f615f4f7f086715d2d212 ]
-
-tl;dr: There is a race in the TDX private<=>shared conversion code
- which could kill the TDX guest. Fix it by changing conversion
- ordering to eliminate the window.
-
-TDX hardware maintains metadata to track which pages are private and
-shared. Additionally, TDX guests use the guest x86 page tables to
-specify whether a given mapping is intended to be private or shared.
-Bad things happen when the intent and metadata do not match.
-
-So there are two thing in play:
- 1. "the page" -- the physical TDX page metadata
- 2. "the mapping" -- the guest-controlled x86 page table intent
-
-For instance, an unrecoverable exit to VMM occurs if a guest touches a
-private mapping that points to a shared physical page.
-
-In summary:
- * Private mapping => Private Page == OK (obviously)
- * Shared mapping => Shared Page == OK (obviously)
- * Private mapping => Shared Page == BIG BOOM!
- * Shared mapping => Private Page == OK-ish
- (It will read generate a recoverable #VE via handle_mmio())
-
-Enter load_unaligned_zeropad(). It can touch memory that is adjacent but
-otherwise unrelated to the memory it needs to touch. It will cause one
-of those unrecoverable exits (aka. BIG BOOM) if it blunders into a
-shared mapping pointing to a private page.
-
-This is a problem when __set_memory_enc_pgtable() converts pages from
-shared to private. It first changes the mapping and second modifies
-the TDX page metadata. It's moving from:
-
- * Shared mapping => Shared Page == OK
-to:
- * Private mapping => Shared Page == BIG BOOM!
-
-This means that there is a window with a shared mapping pointing to a
-private page where load_unaligned_zeropad() can strike.
-
-Add a TDX handler for guest.enc_status_change_prepare(). This converts
-the page from shared to private *before* the page becomes private. This
-ensures that there is never a private mapping to a shared page.
-
-Leave a guest.enc_status_change_finish() in place but only use it for
-private=>shared conversions. This will delay updating the TDX metadata
-marking the page private until *after* the mapping matches the metadata.
-This also ensures that there is never a private mapping to a shared page.

-Subject: x86/xen: Set MTRR state when running as Xen PV initial domain
-
-From: Juergen Gross <jgross@suse.com>
-
-[ Upstream commit a153f254e5cdf8fa3a1df90a6ffed3063fede154 ]
-
-When running as Xen PV initial domain (aka dom0), MTRRs are disabled
-by the hypervisor, but the system should nevertheless use correct
-cache memory types. This has always kind of worked, as disabled MTRRs
-resulted in disabled PAT, too, so that the kernel avoided code paths
-resulting in inconsistencies. This bypassed all of the sanity checks
-the kernel is doing with enabled MTRRs in order to avoid memory
-mappings with conflicting memory types.
-
-This has been changed recently, leading to PAT being accepted to be
-enabled, while MTRRs stayed disabled. The result is that
-mtrr_type_lookup() no longer is accepting all memory type requests,
-but started to return WB even if UC- was requested. This led to
-driver failures during initialization of some devices.
-
-In reality MTRRs are still in effect, but they are under complete
-control of the Xen hypervisor. It is possible, however, to retrieve
-the MTRR settings from the hypervisor.
-
-In order to fix those problems, overwrite the MTRR state via
-mtrr_overwrite_state() with the MTRR data from the hypervisor, if the
-system is running as a Xen dom0.
