+Subject: accel/ivpu: Fix deadlock in ivpu_ms_cleanup()
+
+From: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com>
+
+commit 9a6f56762d23a1f3af15e67901493c927caaf882 upstream.
+
+Fix deadlock in ivpu_ms_cleanup() by preventing runtime resume after
+file_priv->ms_lock is acquired.
+
+During a failure in runtime resume, a cold boot is executed, which
+calls ivpu_ms_cleanup_all(). This function calls ivpu_ms_cleanup()
+that acquires file_priv->ms_lock and causes the deadlock.

+Subject: accel/ivpu: Fix PM related deadlocks in MS IOCTLs
+
+From: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com>
+
+commit d893da85e06edf54737bb80648bb58ba8fd56d9f upstream.
+
+Prevent runtime resume/suspend while MS IOCTLs are in progress.
+Failed suspend will call ivpu_ms_cleanup() that would try to acquire
+file_priv->ms_lock, which is already held by the IOCTLs.

+
+From: Sharan Kumar M <sharweshraajan@gmail.com>
+
+commit e5182305a5199246dbcb4053299dcb1c8867b6ff upstream.
+
+This patch adds the HP OMEN 16 Laptop xd000xx to enable mute led.
+it uses ALC245_FIXUP_HP_MUTE_LED_COEFBIT with a slight modification
+setting mute_led_coef.off to 0(it was set to 4 i guess
+in that function) which i referred to your previous patch disscusion
+https://bugzilla.kernel.org/show_bug.cgi?id=214735 .
+i am not sure whether i can modify the current working function so i
+added another version calling
+ALC245_FIXUP_HP_MUTE_LED_V1_COEFBIT. and both works for me.
+
+Tested on 6.13.4-arch1-1 to 6.14.0-arch1-1

+Subject: arm64: errata: Assume that unknown CPUs _are_ vulnerable to Spectre BHB
+
+From: Douglas Anderson <dianders@chromium.org>
+
+commit e403e8538359d8580cbee1976ff71813e947101e upstream.
+
+The code for detecting CPUs that are vulnerable to Spectre BHB was
+based on a hardcoded list of CPU IDs that were known to be affected.
+Unfortunately, the list mostly only contained the IDs of standard ARM
+cores. The IDs for many cores that are minor variants of the standard
+ARM cores (like many Qualcomm Kyro CPUs) weren't listed. This led the
+code to assume that those variants were not affected.
+
+Flip the code on its head and instead assume that a core is vulnerable
+if it doesn't have CSV2_3 but is unrecognized as being safe. This
+involves creating a "Spectre BHB safe" list.
+
+As of right now, the only CPU IDs added to the "Spectre BHB safe" list
+are ARM Cortex A35, A53, A55, A510, and A520. This list was created by
+looking for cores that weren't listed in ARM's list [1] as per review
+feedback on v2 of this patch [2]. Additionally Brahma A53 is added as
+per mailing list feedback [3].
+
+NOTE: this patch will not actually _mitigate_ anyone, it will simply
+cause them to report themselves as vulnerable. If any cores in the
+system are reported as vulnerable but not mitigated then the whole
+system will be reported as vulnerable though the system will attempt
+to mitigate with the information it has about the known cores.

+
+From: Haoxiang Li <haoxiang_li2024@163.com>
+
+commit 3e330acf4efd63876d673c046cd073a1d4ed57a8 upstream.
+
+When snd_soc_dapm_new_controls() or snd_soc_dapm_add_routes() fails,
+wcd937x_soc_codec_probe() returns without releasing 'wcd937x->clsh_info',
+which is allocated by wcd_clsh_ctrl_alloc. Add wcd_clsh_ctrl_free()
+to prevent potential memory leak.

+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit 0badb5432fd525a00db5630c459b635e9d47f445 upstream.
+
+Implement an helper function in q6apm to be able to read the current
+hardware pointer for both read and write buffers.
+
+This should help q6apm-dai to get the hardware pointer consistently
+without it doing manual calculation, which could go wrong in some race
+conditions.

+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit a93dad6f4e6a04a5943f6ee5686585f24abf7063 upstream.
+
+With the existing code, the buffer position is only reset in pointer
+callback, which leaves the possiblity of it going over the size of
+buffer size and reporting incorrect position to userspace.
+
+Without this patch, its possible to see errors like:
+snd-x1e80100 sound: invalid position: pcmC0D0p:0, pos = 12288, buffer size = 12288, period size = 1536
+snd-x1e80100 sound: invalid position: pcmC0D0p:0, pos = 12288, buffer size = 12288, period size = 1536

+Subject: ASoC: q6apm-dai: schedule all available frames to avoid dsp under-runs
+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit 3d4a4411aa8bbc3653ff22a1ff0432eb93d22ae0 upstream.
+
+With the existing code, we are only setting up one period at a time, in a
+ping-pong buffer style. This triggers lot of underruns in the dsp
+leading to jitter noise during audio playback.
+
+Fix this by scheduling all available periods, this will ensure that the dsp
+has enough buffer feed and ultimatley fixing the underruns and audio
+distortion.
+
+Fixes: 9b4fe0f1cd79 ("ASoC: qdsp6: audioreach: add q6apm-dai support")

+Subject: ASoC: qdsp6: q6apm-dai: set 10 ms period and buffer alignment.
+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit 3107019501842c27334554ba9d6583b1f200f61f upstream.
+
+DSP expects the periods to be aligned to fragment sizes, currently
+setting up to hw constriants on periods bytes is not going to work
+correctly as we can endup with periods sizes aligned to 32 bytes however
+not aligned to fragment size.
+
+Update the constriants to use fragment size, and also set at step of
+10ms for period size to accommodate DSP requirements of 10ms latency.

+Subject: ASoC: qdsp6: q6asm-dai: fix q6asm_dai_compr_set_params error path
+
+From: Alexey Klimov <alexey.klimov@linaro.org>
+
+commit 7eccc86e90f04a0d758d16c08627a620ac59604d upstream.
+
+In case of attempts to compress playback something, for instance,
+when audio routing is not set up correctly, the audio DSP is left in
+inconsistent state because we are not doing the correct things in
+the error path of q6asm_dai_compr_set_params().
+
+So, when routing is not set up and compress playback is attempted
+the following errors are present (simplified log):
+
+q6routing routing: Routing not setup for MultiMedia-1 Session
+q6asm-dai dais: Stream reg failed ret:-22
+q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params()
+on 17300000.remoteproc:glink-edge:apr:service@7:dais
+
+After setting the correct routing the compress playback will always fail:
+
+q6asm-dai dais: cmd = 0x10db3 returned error = 0x9
+q6asm-dai dais: DSP returned error[9]
+q6asm-dai dais: q6asm_open_write failed
+q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params()
+on 17300000.remoteproc:glink-edge:apr:service@7:dais
+
+0x9 here means "Operation is already processed". The CMD_OPEN here was
+sent the second time hence DSP responds that it was already done.
+
+Turns out the CMD_CLOSE should be sent after the q6asm_open_write()
+succeeded but something failed after that, for instance, routing
+setup.
+
+Fix this by slightly reworking the error path in
+q6asm_dai_compr_set_params().
+
+Tested on QRB5165 RB5 and SDM845 RB3 boards.

+Subject: bus: mhi: host: Fix race between unprepare and queue_buf
+
+From: Jeff Hugo <quic_jhugo@quicinc.com>
+
+commit 0686a818d77a431fc3ba2fab4b46bbb04e8c9380 upstream.
+
+A client driver may use mhi_unprepare_from_transfer() to quiesce
+incoming data during the client driver's tear down. The client driver
+might also be processing data at the same time, resulting in a call to
+mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
+after mhi_unprepare_from_transfer() has torn down the channel, a panic
+will occur due to an invalid dereference leading to a page fault.
+
+This occurs because mhi_gen_tre() does not verify the channel state
+after locking it. Fix this by having mhi_gen_tre() confirm the channel
+state is valid, or return error to avoid accessing deinitialized data.

+
+commit 3a544a39e0a4c492e3026dfbed018321d2bd6caa upstream.
+
+The MIPID02 can use up to 2 data lanes which leads to having a maximum
+item number of 3 for the lane-polarities since this also contains the
+clock lane.

+Subject: f2fs: fix to avoid atomicity corruption of atomic file
+
+From: Yeongjin Gil <youngjin.gil@samsung.com>
+
+commit f098aeba04c9328571567dca45159358a250240c upstream.
+
+In the case of the following call stack for an atomic file,
+FI_DIRTY_INODE is set, but FI_ATOMIC_DIRTIED is not subsequently set.
+
+f2fs_file_write_iter
+ f2fs_map_blocks
+ f2fs_reserve_new_blocks
+ inc_valid_block_count
+ __mark_inode_dirty(dquot)
+ f2fs_dirty_inode
+
+If FI_ATOMIC_DIRTIED is not set, atomic file can encounter corruption
+due to a mismatch between old file size and new data.
+
+To resolve this issue, I changed to set FI_ATOMIC_DIRTIED when
+FI_DIRTY_INODE is set. This ensures that FI_DIRTY_INODE, which was
+previously cleared by the Writeback thread during the commit atomic, is
+set and i_size is updated.

+As the comment states, io_req_post_cqe() should only be used by

+not. Add a flag signifying whether a request wants to post multiple

+
+From: Will Deacon <will@kernel.org>
+
+commit 250f25367b58d8c65a1b060a2dda037eea09a672 upstream.
+
+If kvm_arch_vcpu_create() fails to share the vCPU page with the
+hypervisor, we propagate the error back to the ioctl but leave the
+vGIC vCPU data initialised. Note only does this leak the corresponding
+memory when the vCPU is destroyed but it can also lead to use-after-free
+if the redistributor device handling tries to walk into the vCPU.
+
+Add the missing cleanup to kvm_arch_vcpu_create(), ensuring that the
+vGIC vCPU structures are destroyed on error.

+
+In case of multiple active instances, new interrupts can occur as soon

+instance_info after clearing the interrupt, then there is no guarantee,
+that the instance_info is still valid for the current interrupt.

+Read the instance_info register for each interrupt before clearing the

+commit 6bae4d5053da634eecb611118e7cd91a677a4bbf upstream.
+
+When a decoder instance is created, the W5_CMD_ERR_CONCEAL register
+should be initialized to 0. Otherwise, gray color is occasionally
+displayed on the screen while decoding.

+Subject: media: chips-media: wave5: Fix timeout while testing 10bit hevc fluster
+
+From: Jackson.lee <jackson.lee@chipsnmedia.com>
+
+commit 035371c9e5098018b8512efc6a8812912469480c upstream.
+
+The Wave5 521C variant does not support 10 bit decoding. When 10 bit
+decoding support was added for the 515 variant, a section of the code
+was removed which returned an error. This removal causes a timeout for
+the 521 variant, which was discovered during HEVC 10-bit decoding tests.

+From: Hans de Goede <hdegoede@redhat.com>
+
+commit ed554da65abd0c561e40d35272d1a61d030fe977 upstream.
+
+Commit 7d968b5badfc ("media: hi556: Return -EPROBE_DEFER if no endpoint is
+found") moved the v4l2_fwnode_endpoint_alloc_parse() call in
+hi556_check_hwcfg() up, but it did not make the error-exit paths between
+the old and new call-site use "goto check_hwcfg_error;" to free the bus_cfg
+on errors.
+
+Add the missing "goto check_hwcfg_error;" statements to fix a memleak on
+early error-exits from hi556_check_hwcfg().

+
+commit 9e38acacb9d809b97a0bdc5c76e725355a47158a upstream.
+
+The mask to select the test-pattern in register ADV748X_SDP_FRP is
+incorrect, it's the lower 3 bits which controls the pattern. The
+GENMASK() macro is used incorrectly and the generated mask is 0x0e
+instead of 0x07.
+
+The result is that not all test patterns are selectable, and that in
+some cases the wrong test pattern is activated. Fix this by correcting
+the GENMASK().

+
+commit ccc888d1698b6f42d52ddf5cecfe50fe925c95e5 upstream.
+
+There were multiple issues in the driver's probe function related to
+error handling:
+
+- Device's PM runtime status wasn't reverted to suspended on some errors
+ in probe.
+
+- Runtime PM was left enabled for the device on some probe errors.
+
+- Device was left powered on if a probe failure happened or when it
+ was removed when it was powered on.
+
+- An extra pm_runtime_set_suspended() was issued in driver's remove
+ function when the device was suspended.
+
+Fix these bugs.

+
+Set the device's runtime PM status and enable runtime PM before

+the device is runtime PM resumed while runtime PM has not been enabled
+yet.
+
+Also set the device's runtime PM status to suspended in remove only if it

+Subject: media: i2c: imx319: Rectify runtime PM handling probe and remove
+
+From: Sakari Ailus <sakari.ailus@linux.intel.com>
+
+commit 5f5ffd3bc62b2e6c478061918b10473d8b90ac2d upstream.
+
+Idle the device only after the async sub-device has been successfully
+registered. In error handling, set the device's runtime PM status to
+suspended only if it has been set to active previously in probe.
+
+Also set the device's runtime PM status to suspended in remove only if it
+wasn't so already.

+Subject: media: imx219: Adjust PLL settings based on the number of MIPI lanes
+
+From: Dave Stevenson <dave.stevenson@raspberrypi.com>
+
+commit 591a07588c03437dbcc3addfff07675de95a461e upstream.
+
+Commit ceddfd4493b3 ("media: i2c: imx219: Support four-lane operation")
+added support for device tree to allow configuration of the sensor to
+use 4 lanes with a link frequency of 363MHz, and amended the advertised
+pixel rate to 280.8MPix/s.
+
+However it didn't change any of the PLL settings, so actually it would
+have been running overclocked in the MIPI block, and with the frame
+rate and exposure calculations being wrong as the pixel rate was
+unchanged.
+
+The pixel rate and link frequency advertised were taken from the "Clock
+Setting Example" section of the datasheet. However those are based on an
+external clock of 12MHz, and are unachievable with a clock of 24MHz - it
+seems PREPLLCLK_VT_DIV and PREPLLCK_OP_DIV can ONLY be set via the
+automatic configuration documented in "9-1-2 EXCK_FREQ setting depend on
+INCK frequency", not by writing the registers.
+The closest we can get with a 24MHz clock is 281.6MPix/s and 364MHz.
+
+Dropping all support for the 363MHz link frequency would cause problems
+for existing users, so allow it, but log a warning that the requested
+value is being changed to the supported one.
+

+Subject: media: intel/ipu6: set the dev_parent of video device to pdev
+
+From: Bingbu Cao <bingbu.cao@intel.com>
+
+commit 6f0ab5d3671f7cbb326c8cab6fb69cb7ab9901cc upstream.
+
+The bus_info in v4l2_capability of IPU6 isys v4l2_dev is missing.
+The driver didn't set the dev_parent of v4l2_dev, its parent is set
+to its parent auxdev which is neither platform nor PCI device, thus
+media_set_bus_info() will not set the bus_info of v4l2_capability, then
+`v4l2-ctl --all` cannot show the bus_info.
+
+This patch fixes it by setting the dev_parent of video_device and v4l2
+framework can detect the device type and set the bus_info instead.

+
+commit 450acf0840232eaf6eb7a80da11cf492e57498e8 upstream.
+
+The reason why this passed unnoticed is that most infotainment systems
+use frequencies near enough the middle (50MHz) where both sets work.

+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit 07df4f23ef3ffe6fee697cd2e03623ad27108843 upstream.
+
+This is one of three clang warnings about incompatible enum types
+in a conditional expression:
+
+drivers/media/platform/mediatek/vcodec/encoder/venc/venc_h264_if.c:597:29: error: conditional expression between different enumeration types ('enum scp_ipi_id' and 'enum ipi_id') [-Werror,-Wenum-compare-conditional]
+ 597 | inst->vpu_inst.id = is_ext ? SCP_IPI_VENC_H264 : IPI_VENC_H264;
+ | ^ ~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~
+
+The code is correct, so just rework it to avoid the warning.

+From: Murad Masimov <m.masimov@mt-integration.ru>
+
+commit 549f6d348167fb2f7800ed7c8d4bce9630c74498 upstream.
+
+If streamzap_callback() receives an urb with any non-critical error
+status, i.e. any error code other than -ECONNRESET, -ENOENT or -ESHUTDOWN,
+it will try to process IR data, ignoring a possible transfer failure.
+
+Make streamzap_callback() process IR data only when urb->status is 0.
+Move processing logic to a separate function to make code cleaner and
+more similar to the URB completion handlers in other RC drivers.

+
+commit 3edd1fc48d2c045e8259561797c89fe78f01717e upstream.
+
+In v4l2_detect_gtf(), it seems safer to cast the 32-bit image_width

+a possible overflow. The resulting object code even seems to
+look better, at least on x86_64.

+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit f4b211714bcc70effa60c34d9fa613d182e3ef1e upstream.
+
+sfr->buf_size is in shared memory and can be modified by malicious user.
+OOB write is possible when the size is made higher than actual sfr data
+buffer. Cap the size to allocated size for such cases.

+Subject: media: venus: hfi: add check to handle incorrect queue size
+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 69baf245b23e20efda0079238b27fc63ecf13de1 upstream.
+
+qsize represents size of shared queued between driver and video
+firmware. Firmware can modify this value to an invalid large value. In
+such situation, empty_space will be bigger than the space actually
+available. Since new_wr_idx is not checked, so the following code will
+result in an OOB write.
+...
+qsize = qhdr->q_size
+
+if (wr_idx >= rd_idx)
+ empty_space = qsize - (wr_idx - rd_idx)
+....
+if (new_wr_idx < qsize) {
+ memcpy(wr_ptr, packet, dwords << 2) --> OOB write
+
+Add check to ensure qsize is within the allocated size while
+reading and writing packets into the queue.

+
+commit 172bf5a9ef70a399bb227809db78442dc01d9e48 upstream.
+
+There is a possibility that init_codecs is invoked multiple times during
+manipulated payload from video firmware. In such case, if codecs_count
+can get incremented to value more than MAX_CODEC_NUM, there can be OOB
+access. Reset the count so that it always starts from beginning.

+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 9edaaa8e3e15aab1ca413ab50556de1975bcb329 upstream.
+
+words_count denotes the number of words in total payload, while data
+points to payload of various property within it. When words_count
+reaches last word, data can access memory beyond the total payload. This
+can lead to OOB access. With this patch, the utility api for handling
+individual properties now returns the size of data consumed. Accordingly
+remaining bytes are calculated before parsing the payload, thereby
+eliminates the OOB access possibilities.

+From: Matthew Majewski <mattwmajewski@gmail.com>
+
+commit 143d75583f2427f3a97dba62413c4f0604867ebf upstream.
+
+Move the v4l2_info() call displaying the video device name after the
+device is actually registered.
+
+This fixes a bug where the driver was always displaying "/dev/video0"
+since it was reading from the vfd before it was registered.

+
+From: Nicolas Dufresne <nicolas.dufresne@collabora.com>
+
+commit d98e9213a768a3cc3a99f5e1abe09ad3baff2104 upstream.
+
+The visl driver supports both frame and slice mode, with and without a
+start-code. But, the range and default for these enum controls was not
+set, which currently limits the decoder to enums with a value of 0. Fix
+this by setting the decoder mode and start code controls for both the
+H.264 and HEVC codecs.

+
+From: Matthieu Baerts (NGI0) <matttbe@kernel.org>
+
+commit e2f4ac7bab2205d3c4dd9464e6ffd82502177c51 upstream.
+
+When adding a socket option support in MPTCP, both the get and set parts
+are supposed to be implemented.
+
+IP(V6)_FREEBIND and IP(V6)_TRANSPARENT support for the setsockopt part
+has been added a while ago, but it looks like the get part got
+forgotten. It should have been present as a way to verify a setting has
+been set as expected, and not to act differently from TCP or any other
+socket types.
+
+Everything was in place to expose it, just the last step was missing.
+Only new code is added to cover these specific getsockopt(), that seems
+safe.

+Subject: mptcp: sockopt: fix getting IPV6_V6ONLY
+
+From: Matthieu Baerts (NGI0) <matttbe@kernel.org>
+
+commit 8c39633759885b6ff85f6d96cf445560e74df5e8 upstream.
+
+When adding a socket option support in MPTCP, both the get and set parts
+are supposed to be implemented.
+
+IPV6_V6ONLY support for the setsockopt part has been added a while ago,
+but it looks like the get part got forgotten. It should have been
+present as a way to verify a setting has been set as expected, and not
+to act differently from TCP or any other socket types.
+
+Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want
+to check the default value, before doing extra actions. On Linux, the
+default value is 0, but this can be changed with the net.ipv6.bindv6only
+sysctl knob. On Windows, it is set to 1 by default. So supporting the
+get part, like for all other socket options, is important.
+
+Everything was in place to expose it, just the last step was missing.
+Only new code is added to cover this specific getsockopt(), that seems
+safe.

+
+The fix uses the higher level nand_reset(chip, chipnr); where chipnr = 0, when
+doing PM resume operation in compliance with the controller support for single
+die nand chip. Switching from nand_reset_op() to nand_reset() implies more
+than just setting the cs field op->cs, it also reconfigures the data interface
+(ie. the timings). Tested and confirmed the NAND chip is in sync timing wise
+with host after the fix.

+commit abd88757252c2a2cea7909f3922de1f0e9e04002 upstream.
+
+This reverts commit 9bc92332cc3f06fda3c6e2423995ca2da0a7ec9a.
+
+Revert this "fix" as it's not really helpful but makes backporting a
+proper fix harder.

+Subject: smb311 client: fix missing tcon check when mounting with linux/posix extensions
+
+From: Steve French <stfrench@microsoft.com>
+
+commit b365b9d404b7376c60c91cd079218bfef11b7822 upstream.
+
+When mounting the same share twice, once with the "linux" mount parameter
+(or equivalently "posix") and then once without (or e.g. with "nolinux"),
+we were incorrectly reusing the same tree connection for both mounts.
+This meant that the first mount of the share on the client, would
+cause subsequent mounts of that same share on the same client to
+ignore that mount parm ("linux" vs. "nolinux") and incorrectly reuse
+the same tcon.

+Subject: spi: cadence-qspi: Fix probe on AM62A LP SK
+
+From: Miquel Raynal <miquel.raynal@bootlin.com>
+
+commit b8665a1b49f5498edb7b21d730030c06b7348a3c upstream.
+
+In 2020, there's been an unnoticed change which rightfully attempted to
+report probe deferrals upon DMA absence by checking the return value of
+dma_request_chan_by_mask(). By doing so, it also reported errors which
+were simply ignored otherwise, likely on purpose.
+
+This change actually turned a void return into an error code. Hence, not
+only the -EPROBE_DEFER error codes but all error codes got reported to
+the callers, now failing to probe in the absence of Rx DMA channel,
+despite the fact that DMA seems to not be supported natively by many
+implementations.
+
+Looking at the history, this change probably led to:
+ad2775dc3fc5 ("spi: cadence-quadspi: Disable the DAC for Intel LGM SoC")
+f724c296f2f2 ("spi: cadence-quadspi: fix Direct Access Mode disable for SoCFPGA")
+
+In my case, the AM62A LP SK core octo-SPI node from TI does not
+advertise any DMA channel, hinting that there is likely no support for
+it, but yet when the support for the am654 compatible was added, DMA
+seemed to be used, so just discarding its use with the
+CQSPI_DISABLE_DAC_MODE quirk for this compatible does not seem the
+correct approach.
+
+Let's get change the return condition back to:
+- return a probe deferral error if we get one
+- ignore the return value otherwise
+The "error" log level was however likely too high for something that is
+expected to fail, so let's lower it arbitrarily to the info level.
+

+
+From: Olga Kornievskaia <okorniev@redhat.com>
+
+commit 750037aa0a9f28d84df3dcf319a28423d69092fd upstream.
+
+On an rdma-capable machine, a start/stop/start and then on a stop of
+a knfsd server would lead kref underflow warning because svc_rdma_free
+would indiscriminately unregister the rdma device but a listening
+transport never calls the rdma_rn_register() thus leading to kref
+going down to 0 on the 1st stop of the server and on the 2nd stop
+it leads to a problem.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+From: Jonathan McDowell <noodles@meta.com>
+
+commit 7146dffa875cd00e7a7f918e1fce79c7593ac1fa upstream.
+
+The change to only use interrupts to handle supported status changes
+introduced an issue when it is necessary to poll for the status. Rather
+than checking for the status after sleeping the code now sleeps after
+the check. This means a correct, but slower, status change on the part
+of the TPM can be missed, resulting in a spurious timeout error,
+especially on a more loaded system. Switch back to sleeping *then*
+checking. An up front check of the status has been done at the start of
+the function, so this does not cause an additional delay when the status
+is already what we're looking for.

+Subject: udf: Fix inode_getblk() return value
+
+From: Jan Kara <jack@suse.cz>
+
+commit 6afdc60ec30b0a9390d11b7cebed79c857ce82aa upstream.
+
+Smatch noticed that inode_getblk() can return 1 on successful mapping of
+a block instead of expected 0 after commit b405c1e58b73 ("udf: refactor
+udf_next_aext() to handle error"). This could confuse some of the
+callers and lead to strange failures (although the one reported by
+Smatch in udf_mkdir() is impossible to trigger in practice). Fix the
+return value of inode_getblk().

+create_user_mr() has correct code to count the number of null keys

+does not follow the same to cap the range up to the 1GB limit

+
+commit d00c0c4105e5ab8a6a13ed23d701cceb285761fa upstream.
+
+Since the new_metric and last_hop_metric variables can reach
+the MAX_METRIC(0xffffffff) value, an integer overflow may occur
+when multiplying them by 10/9. It can lead to incorrect behavior.

+Subject: wifi: mt76: mt7925: fix the wrong simultaneous cap for MLO
+
+From: Ming Yen Hsieh <mingyen.hsieh@mediatek.com>
+
+commit 7dcea6fe33ee3d7cbb65baee0dd7adc76d1c9ddc upstream.
+
+The mt7925 chip is only support a single radio, so the maximum
+number of simultaneous should be 0.

+Subject: xenfs/xensyms: respect hypervisor's "next" indication
+
+From: Jan Beulich <jbeulich@suse.com>
+
+commit 5c4e79e29a9fe4ea132118ac40c2bc97cfe23077 upstream.
+
+The interface specifies the symnum field as an input and output; the
+hypervisor sets it to the next sequential symbol's index. xensyms_next()
+incrementing the position explicitly (and xensyms_next_sym()
+decrementing it to "rewind") is only correct as long as the sequence of
+symbol indexes is non-sparse. Use the hypervisor-supplied value instead
+to update the position in xensyms_next(), and use the saved incoming
+index in xensyms_next_sym().
