+Subject: ACPI: processor: idle: Return an error if both P_LVL{2,3} idle states
+ are invalid
+
+From: Giovanni Gherdovich <ggherdovich@suse.cz>
+
+[ Upstream commit 9e9b893404d43894d69a18dd2fc8fcf1c36abb7e ]
+
+Prior to commit 496121c02127 ("ACPI: processor: idle: Allow probing on
+platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
+systems without a valid C-State at least as deep as C2.
+
+The behavior was desirable for guests on hypervisors such as VMWare
+ESXi, which by default don't have the _CST ACPI method, and set the C2
+and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
+to signify they're unsupported.
+
+Since the above change though, these virtualized deployments end up
+loading acpi_idle, and thus entering the default C1 C-State set by
+acpi_processor_get_power_info_default(); this is undesirable for a
+system that's communicating to the OS it doesn't want C-States (missing
+_CST, and invalid C2/C3 in FADT).
+
+Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
+so that acpi_processor_get_cstate_info() exits early and doesn't set
+pr->flags.power = 1.

+Subject: affs: don't write overlarge OFS data block size fields
+
+From: Simon Tatham <anakin@pobox.com>
+
+[ Upstream commit 011ea742a25a77bac3d995f457886a67d178c6f0 ]
+
+If a data sector on an OFS floppy contains a value > 0x1e8 (the
+largest amount of data that fits in the sector after its header), then
+an Amiga reading the file can return corrupt data, by taking the
+overlarge size at its word and reading past the end of the buffer it
+read the disk sector into!
+
+The cause: when affs_write_end_ofs() writes data to an OFS filesystem,
+the new size field for a data block was computed by adding the amount
+of data currently being written (into the block) to the existing value
+of the size field. This is correct if you're extending the file at the
+end, but if you seek backwards in the file and overwrite _existing_
+data, it can lead to the size field being larger than the maximum
+legal value.
+
+This commit changes the calculation so that it sets the size field to
+the max of its previous size and the position within the block that we
+just wrote up to.

+Subject: affs: generate OFS sequence numbers starting at 1
+
+From: Simon Tatham <anakin@pobox.com>
+
+[ Upstream commit e4cf8ec4de4e13f156c1d61977d282d90c221085 ]
+
+If I write a file to an OFS floppy image, and try to read it back on
+an emulated Amiga running Workbench 1.3, the Amiga reports a disk
+error trying to read the file. (That is, it's unable to read it _at
+all_, even to copy it to the NIL: device. It isn't a matter of getting
+the wrong data and being unable to parse the file format.)
+
+This is because the 'sequence number' field in the OFS data block
+header is supposed to be based at 1, but affs writes it based at 0.
+All three locations changed by this patch were setting the sequence
+number to a variable 'bidx' which was previously obtained by dividing
+a file position by bsize, so bidx will naturally use 0 for the first
+block. Therefore all three should add 1 to that value before writing
+it into the sequence number field.
+
+With this change, the Amiga successfully reads the file.
+
+For data block reference: https://wiki.osdev.org/FFS_(Amiga)

+Subject: ALSA: hda/realtek: Always honor no_shutup_pins
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit 5a0c72c1da3cbc0cd4940a95d1be2830104c6edf ]
+
+The workaround for Dell machines to skip the pin-shutup for mic pins
+introduced alc_headset_mic_no_shutup() that is replaced from the
+generic snd_hda_shutup_pins() for certain codecs.  The problem is that
+the call is done unconditionally even if spec->no_shutup_pins is set.
+This seems causing problems on other platforms like Lenovo.
+
+This patch corrects the behavior and the driver honors always
+spec->no_shutup_pins flag and skips alc_headset_mic_no_shutup() if
+it's set.

+Subject: ASoC: ti: j721e-evm: Fix clock configuration for ti,j7200-cpb-audio
+ compatible
+
+From: Jayesh Choudhary <j-choudhary@ti.com>
+
+[ Upstream commit 45ff65e30deb919604e68faed156ad96ce7474d9 ]
+
+For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for
+48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of
+J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.
+Add support for these rates by using the 48k parent clock and adjusting
+the clock for these rates later in j721e_configure_refclk.

+Subject: bpf: Use preempt_count() directly in bpf_send_signal_common()
+
+From: Hou Tao <houtao1@huawei.com>
+
+[ Upstream commit b4a8b5bba712a711d8ca1f7d04646db63f9c88f5 ]
+
+bpf_send_signal_common() uses preemptible() to check whether or not the
+current context is preemptible. If it is preemptible, it will use
+irq_work to send the signal asynchronously instead of trying to hold a
+spin-lock, because spin-lock is sleepable under PREEMPT_RT.
+
+However, preemptible() depends on CONFIG_PREEMPT_COUNT. When
+CONFIG_PREEMPT_COUNT is turned off (e.g., CONFIG_PREEMPT_VOLUNTARY=y),
+!preemptible() will be evaluated as 1 and bpf_send_signal_common() will
+use irq_work unconditionally.
+
+Fix it by unfolding "!preemptible()" and using "preempt_count() != 0 ||
+irqs_disabled()" instead.

+Subject: can: statistics: use atomic access in hot path
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+[ Upstream commit 80b5f90158d1364cbd80ad82852a757fc0692bf2 ]
+
+In can_send() and can_receive() CAN messages and CAN filter matches are
+counted to be visible in the CAN procfs files.
+
+KCSAN detected a data race within can_send() when two CAN frames have
+been generated by a timer event writing to the same CAN netdevice at the
+same time. Use atomic operations to access the statistics in the hot path
+to fix the KCSAN complaint.

+[ Upstream commit 0079e77c08de692cb20b38e408365c830a44b1ef ]
+
+The bit index of the peripheral clock for mmc A is wrong
+This was probably not a problem for mmc A as the peripheral is likely left
+enabled by the bootloader.
+
+No issues has been reported so far but it could be a problem, most likely
+some form of conflict between the ethernet and mmc A clock, breaking
+ethernet on init.
+
+Use the value provided by the documentation for mmc A before this
+becomes an actual problem.

+
+[ Upstream commit 8995f8f108c3ac5ad52b12a6cfbbc7b3b32e9a58 ]
+
+Several clocks used by both g12a and g12b use the g12a cpu A clock hw
+pointer as clock parent. This is incorrect on g12b since the parents of
+cluster A cpu clock are different. Also the hw clock provided as parent to
+these children is not even registered clock on g12b.
+
+Fix the problem by reverting to the global namespace and let CCF pick
+the appropriate, as it is already done for other clocks, such as
+cpu_clk_trace_div.

+
+From: Jerome Brunet <jbrunet@baylibre.com>
+
+[ Upstream commit f38f7fe4830c5cb4eac138249225f119e7939965 ]
+
+gxbb_32k_clk_div sets CLK_DIVIDER_ROUND_CLOSEST in the init_data flag which
+is incorrect. This is field is not where the divider flags belong.
+
+Thankfully, CLK_DIVIDER_ROUND_CLOSEST maps to bit 4 which is an unused
+clock flag, so there is no unintended consequence to this error.
+
+Effectively, the clock has been used without CLK_DIVIDER_ROUND_CLOSEST
+so far, so just drop it.

+
+[ Upstream commit 7915d7d5407c026fa9343befb4d3343f7a345f97 ]
+
+The 32k clock reference a parent 'cts_slow_oscin' with a fixme note saying
+that this clock should be provided by AO controller.
+
+The HW probably has this clock but it does not exist at the moment in
+any controller implementation. Furthermore, referencing clock by the global
+name should be avoided whenever possible.
+
+There is no reason to keep this hack around, at least for now.

+Subject: cpufreq: governor: Fix negative 'idle_time' handling in dbs_update()
+
+From: Jie Zhan <zhanjie9@hisilicon.com>
+
+[ Upstream commit 3698dd6b139dc37b35a9ad83d9330c1f99666c02 ]
+
+We observed an issue that the CPU frequency can't raise up with a 100% CPU
+load when NOHZ is off and the 'conservative' governor is selected.
+
+'idle_time' can be negative if it's obtained from get_cpu_idle_time_jiffy()
+when NOHZ is off.  This was found and explained in commit 9485e4ca0b48
+("cpufreq: governor: Fix handling of special cases in dbs_update()").
+
+However, commit 7592019634f8 ("cpufreq: governors: Fix long idle detection
+logic in load calculation") introduced a comparison between 'idle_time' and
+'samling_rate' to detect a long idle interval.  While 'idle_time' is
+converted to int before comparison, it's actually promoted to unsigned
+again when compared with an unsigned 'sampling_rate'.  Hence, this leads to
+wrong idle interval detection when it's in fact 100% busy and sets
+policy_dbs->idle_periods to a very large value.  'conservative' adjusts the
+frequency to minimum because of the large 'idle_periods', such that the
+frequency can't raise up.  'Ondemand' doesn't use policy_dbs->idle_periods
+so it fortunately avoids the issue.
+
+Correct negative 'idle_time' to 0 before any use of it in dbs_update().

+
+The compiler correctly warns that hv_nxc may be used uninitialised
+as that will occur when NX-GZIP is unavailable.
+
+Fix it by rearranging the code and delay setting caps_feat until

+Subject: drm/amd/display: fix type mismatch in
+ CalculateDynamicMetadataParameters()
+
+From: Vitaliy Shevtsov <v.shevtsov@mt-integration.ru>
+
+[ Upstream commit c3c584c18c90a024a54716229809ba36424f9660 ]
+
+There is a type mismatch between what CalculateDynamicMetadataParameters()
+takes and what is passed to it. Currently this function accepts several
+args as signed long but it's called with unsigned integers and integer. On
+some systems where long is 32 bits and one of these unsigned int params is
+greater than INT_MAX it may cause passing input params as negative values.
+
+Fix this by changing these argument types from long to unsigned int and to
+int respectively. Also this will align the function's definition with
+similar functions in other dcn* drivers.
+
+Found by Linux Verification Center (linuxtesting.org) with Svace.

+Subject: drm/amd: Keep display off while going into S4
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+[ Upstream commit 4afacc9948e1f8fdbca401d259ae65ad93d298c0 ]
+
+When userspace invokes S4 the flow is:
+
+1) amdgpu_pmops_prepare()
+2) amdgpu_pmops_freeze()
+3) Create hibernation image
+4) amdgpu_pmops_thaw()
+5) Write out image to disk
+6) Turn off system
+
+Then on resume amdgpu_pmops_restore() is called.
+
+This flow has a problem that because amdgpu_pmops_thaw() is called
+it will call amdgpu_device_resume() which will resume all of the GPU.
+
+This includes turning the display hardware back on and discovering
+connectors again.
+
+This is an unexpected experience for the display to turn back on.
+Adjust the flow so that during the S4 sequence display hardware is
+not turned back on.

+Subject: drm/bridge: ti-sn65dsi86: Fix multiple instances
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit 574f5ee2c85a00a579549d50e9fc9c6c072ee4c4 ]
+
+Each bridge instance creates up to four auxiliary devices with different
+names.  However, their IDs are always zero, causing duplicate filename
+errors when a system has multiple bridges:
+
+    sysfs: cannot create duplicate filename '/bus/auxiliary/devices/ti_sn65dsi86.gpio.0'
+
+Fix this by using a unique instance ID per bridge instance.  The
+instance ID is derived from the I2C adapter number and the bridge's I2C
+address, to support multiple instances on the same bus.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Wayne Lin <Wayne.Lin@amd.com>
+
+[ Upstream commit 6bbce873a9c97cb12f5455c497be279ac58e707f ]
+
+[Why]
+The RAD of sideband message printed today is incorrect.
+For RAD stored within MST branch
+- If MST branch LCT is 1, it's RAD array is untouched and remained as 0.
+- If MST branch LCT is larger than 1, use nibble to store the up facing
+  port number in cascaded sequence as illustrated below:
+
+  u8 RAD[0] = (LCT_2_UFP << 4) | LCT_3_UFP
+     RAD[1] = (LCT_4_UFP << 4) | LCT_5_UFP
+     ...
+
+In drm_dp_mst_rad_to_str(), it wrongly to use BIT_MASK(4) to fetch the port
+number of one nibble.
+
+[How]
+Adjust the code by:
+- RAD array items are valuable only for LCT >= 1.
+- Use 0xF as the mask to replace BIT_MASK(4)
+
+V2:
+- Document how RAD is constructed (Imre)
+
+V3:
+- Adjust the comment for rad[] so kdoc formats it properly (Lyude)
+
+Fixes: 2f015ec6eab6 ("drm/dp_mst: Add sideband down request tracing + selftests")

+Subject: drm/mediatek: dsi: fix error codes in mtk_dsi_host_transfer()
+
+From: Dan Carpenter <dan.carpenter@linaro.org>
+
+[ Upstream commit dcb166ee43c3d594e7b73a24f6e8cf5663eeff2c ]
+
+There is a type bug because the return statement:
+
+        return ret < 0 ? ret : recv_cnt;
+
+The issue is that ret is an int, recv_cnt is a u32 and the function
+returns ssize_t, which is a signed long.  The way that the type promotion
+works is that the negative error codes are first cast to u32 and then
+to signed long.  The error codes end up being positive instead of
+negative and the callers treat them as success.

+Subject: drm/mediatek: mtk_hdmi: Unregister audio platform device on failure
+
+From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
+
+[ Upstream commit 0be123cafc06eed0fd1227166a66e786434b0c50 ]
+
+The probe function of this driver may fail after registering the
+audio platform device: in that case, the state is not getting
+cleaned up, leaving this device registered.
+
+Adding up to the mix, should the probe function of this driver
+return a probe deferral for N times, we're registering up to N
+audio platform devices and, again, never freeing them up.
+
+To fix this, add a pointer to the audio platform device in the
+mtk_hdmi structure, and add a devm action to unregister it upon
+driver removal or probe failure.

+Subject: exfat: fix the infinite loop in exfat_find_last_cluster()
+
+From: Yuezhang Mo <Yuezhang.Mo@sony.com>
+
+[ Upstream commit b0522303f67255926b946aa66885a0104d1b2980 ]
+
+In exfat_find_last_cluster(), the cluster chain is traversed until
+the EOF cluster. If the cluster chain includes a loop due to file
+system corruption, the EOF cluster cannot be traversed, resulting
+in an infinite loop.
+
+If the number of clusters indicated by the file size is inconsistent
+with the cluster chain length, exfat_find_last_cluster() will return
+an error, so if this inconsistency is found, the traversal can be
+aborted without traversing to the EOF cluster.

+Subject: fuse: fix dax truncate/punch_hole fault path
+
+From: Alistair Popple <apopple@nvidia.com>
+
+[ Upstream commit 7851bf649d423edd7286b292739f2eefded3d35c ]
+
+Patch series "fs/dax: Fix ZONE_DEVICE page reference counts", v9.
+
+Device and FS DAX pages have always maintained their own page reference
+counts without following the normal rules for page reference counting.  In
+particular pages are considered free when the refcount hits one rather
+than zero and refcounts are not added when mapping the page.
+
+Tracking this requires special PTE bits (PTE_DEVMAP) and a secondary
+mechanism for allowing GUP to hold references on the page (see
+get_dev_pagemap).  However there doesn't seem to be any reason why FS DAX
+pages need their own reference counting scheme.
+
+By treating the refcounts on these pages the same way as normal pages we
+can remove a lot of special checks.  In particular pXd_trans_huge()
+becomes the same as pXd_leaf(), although I haven't made that change here.
+It also frees up a valuable SW define PTE bit on architectures that have
+devmap PTE bits defined.
+
+It also almost certainly allows further clean-up of the devmap managed
+functions, but I have left that as a future improvment.  It also enables
+support for compound ZONE_DEVICE pages which is one of my primary
+motivators for doing this work.
+
+This patch (of 20):
+
+FS DAX requires file systems to call into the DAX layout prior to
+unlinking inodes to ensure there is no ongoing DMA or other remote access
+to the direct mapped page.  The fuse file system implements
+fuse_dax_break_layouts() to do this which includes a comment indicating
+that passing dmap_end == 0 leads to unmapping of the whole file.
+
+However this is not true - passing dmap_end == 0 will not unmap anything
+before dmap_start, and further more dax_layout_busy_page_range() will not
+scan any of the range to see if there maybe ongoing DMA access to the
+range.  Fix this by passing -1 for dmap_end to fuse_dax_break_layouts()
+which will invalidate the entire file range to
+dax_layout_busy_page_range().

+Subject: IB/mad: Check available slots before posting receive WRs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Maher Sanalla <msanalla@nvidia.com>
+
+[ Upstream commit 37826f0a8c2f6b6add5179003b8597e32a445362 ]
+
+The ib_post_receive_mads() function handles posting receive work
+requests (WRs) to MAD QPs and is called in two cases:
+1) When a MAD port is opened.
+2) When a receive WQE is consumed upon receiving a new MAD.
+
+Whereas, if MADs arrive during the port open phase, a race condition
+might cause an extra WR to be posted, exceeding the QP’s capacity.
+This leads to failures such as:
+infiniband mlx5_0: ib_post_recv failed: -12
+infiniband mlx5_0: Couldn't post receive WRs
+infiniband mlx5_0: Couldn't start port
+infiniband mlx5_0: Couldn't open port 1
+
+Fix this by checking the current receive count before posting a new WR.
+If the QP’s receive queue is full, do not post additional WRs.

+
+[ Upstream commit 05a5d874f7327b75e9bc4359618017e047cc129c ]
+
+Checking the binary representation of two structs (of the same type)
+for equality doesn't have the same semantic as comparing all members for
+equality. The former might find a difference where the latter doesn't in
+the presence of padding or when ambiguous types like float or bool are
+involved. (Floats typically have different representations for single
+values, like -0.0 vs +0.0, or 0.5 * 2² vs 0.25 * 2³. The type bool has
+at least 8 bits and the raw values 1 and 2 (probably) both evaluate to
+true, but memcmp finds a difference.)
+
+When searching for a channel that already has the configuration we need,
+the comparison by member is the one that is needed.
+
+Convert the comparison accordingly to compare the members one after
+another. Also add a static_assert guard to (somewhat) ensure that when
+struct ad7124_channel_config::config_props is expanded, the comparison
+is adapted, too.
+
+This issue is somewhat theoretic, but using memcmp() on a struct is a
+bad pattern that is worth fixing.

+
+[ Upstream commit 7ac6ea4a3e0898db76aecccd68fb2c403eb7d24e ]
+
+Using RTEXT_FILTER_SKIP_STATS is incorrectly skipping non-stats IPv6
+netlink attributes on link dump. This causes issues on userspace tools,
+e.g iproute2 is not rendering address generation mode as it should due
+to missing netlink attribute.
+
+Move the filling of IFLA_INET6_STATS and IFLA_INET6_ICMP6STATS to a
+helper function guarded by a flag check to avoid hitting the same
+situation in the future.

+Subject: isofs: fix KMSAN uninit-value bug in do_isofs_readdir()
+
+From: Qasim Ijaz <qasdev00@gmail.com>
+
+[ Upstream commit 81a82e8f33880793029cd6f8a766fb13b737e6a7 ]
+
+In do_isofs_readdir() when assigning the variable
+"struct iso_directory_record *de" the b_data field of the buffer_head
+is accessed and an offset is added to it, the size of b_data is 2048
+and the offset size is 2047, meaning
+"de = (struct iso_directory_record *) (bh->b_data + offset);"
+yields the final byte of the 2048 sized b_data block.
+
+The first byte of the directory record (de_len) is then read and
+found to be 31, meaning the directory record size is 31 bytes long.
+The directory record is defined by the structure:
+
+       struct iso_directory_record {
+               __u8 length;                     // 1 byte
+               __u8 ext_attr_length;            // 1 byte
+               __u8 extent[8];                  // 8 bytes
+               __u8 size[8];                    // 8 bytes
+               __u8 date[7];                    // 7 bytes
+               __u8 flags;                      // 1 byte
+               __u8 file_unit_size;             // 1 byte
+               __u8 interleave;                 // 1 byte
+               __u8 volume_sequence_number[4];  // 4 bytes
+               __u8 name_len;                   // 1 byte
+               char name[];                     // variable size
+       } __attribute__((packed));
+
+The fixed portion of this structure occupies 33 bytes. Therefore, a
+valid directory record must be at least 33 bytes long
+(even without considering the variable-length name field).
+Since de_len is only 31, it is insufficient to contain
+the complete fixed header.
+
+The code later hits the following sanity check that
+compares de_len against the sum of de->name_len and
+sizeof(struct iso_directory_record):
+
+       if (de_len < de->name_len[0] + sizeof(struct iso_directory_record)) {
+               ...
+       }
+
+Since the fixed portion of the structure is
+33 bytes (up to and including name_len member),
+a valid record should have de_len of at least 33 bytes;
+here, however, de_len is too short, and the field de->name_len
+(located at offset 32) is accessed even though it lies beyond
+the available 31 bytes.
+
+This access on the corrupted isofs data triggers a KASAN uninitialized
+memory warning. The fix would be to first verify that de_len is at least
+sizeof(struct iso_directory_record) before accessing any
+fields like de->name_len.

+Subject: kexec: initialize ELF lowest address to ULONG_MAX
+
+From: Sourabh Jain <sourabhjain@linux.ibm.com>
+
+[ Upstream commit 9986fb5164c8b21f6439cfd45ba36d8cc80c9710 ]
+
+Patch series "powerpc/crash: use generic crashkernel reservation", v3.
+
+Commit 0ab97169aa05 ("crash_core: add generic function to do reservation")
+added a generic function to reserve crashkernel memory.  So let's use the
+same function on powerpc and remove the architecture-specific code that
+essentially does the same thing.
+
+The generic crashkernel reservation also provides a way to split the
+crashkernel reservation into high and low memory reservations, which can
+be enabled for powerpc in the future.
+
+Additionally move powerpc to use generic APIs to locate memory hole for
+kexec segments while loading kdump kernel.
+
+This patch (of 7):
+
+kexec_elf_load() loads an ELF executable and sets the address of the
+lowest PT_LOAD section to the address held by the lowest_load_addr
+function argument.
+
+To determine the lowest PT_LOAD address, a local variable lowest_addr
+(type unsigned long) is initialized to UINT_MAX.  After loading each
+PT_LOAD, its address is compared to lowest_addr.  If a loaded PT_LOAD
+address is lower, lowest_addr is updated.  However, setting lowest_addr to
+UINT_MAX won't work when the kernel image is loaded above 4G, as the
+returned lowest PT_LOAD address would be invalid.  This is resolved by
+initializing lowest_addr to ULONG_MAX instead.
+
+This issue was discovered while implementing crashkernel high/low
+reservation on the PowerPC architecture.

+The static code analysis tool "Coverity Scan" pointed the following

+Subject: lockdep: Don't disable interrupts on RT in
+ disable_irq_nosync_lockdep.*()
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+[ Upstream commit 87886b32d669abc11c7be95ef44099215e4f5788 ]
+
+disable_irq_nosync_lockdep() disables interrupts with lockdep enabled to
+avoid false positive reports by lockdep that a certain lock has not been
+acquired with disabled interrupts. The user of this macros expects that
+a lock can be acquried without disabling interrupts because the IRQ line
+triggering the interrupt is disabled.
+
+This triggers a warning on PREEMPT_RT because after
+disable_irq_nosync_lockdep.*() the following spinlock_t now is acquired
+with disabled interrupts.
+
+On PREEMPT_RT there is no difference between spin_lock() and
+spin_lock_irq() so avoiding disabling interrupts in this case works for
+the two remaining callers as of today.
+
+Don't disable interrupts on PREEMPT_RT in disable_irq_nosync_lockdep.*().

+
+From: Waiman Long <longman@redhat.com>
+
+[ Upstream commit 85b2b9c16d053364e2004883140538e73b333cdb ]
+
+A circular lock dependency splat has been seen involving down_trylock():
+
+  ======================================================
+  WARNING: possible circular locking dependency detected
+  6.12.0-41.el10.s390x+debug
+  ------------------------------------------------------
+  dd/32479 is trying to acquire lock:
+  0015a20accd0d4f8 ((console_sem).lock){-.-.}-{2:2}, at: down_trylock+0x26/0x90
+
+  but task is already holding lock:
+  000000017e461698 (&zone->lock){-.-.}-{2:2}, at: rmqueue_bulk+0xac/0x8f0
+
+  the existing dependency chain (in reverse order) is:
+  -> #4 (&zone->lock){-.-.}-{2:2}:
+  -> #3 (hrtimer_bases.lock){-.-.}-{2:2}:
+  -> #2 (&rq->__lock){-.-.}-{2:2}:
+  -> #1 (&p->pi_lock){-.-.}-{2:2}:
+  -> #0 ((console_sem).lock){-.-.}-{2:2}:
+
+The console_sem -> pi_lock dependency is due to calling try_to_wake_up()
+while holding the console_sem raw_spinlock. This dependency can be broken
+by using wake_q to do the wakeup instead of calling try_to_wake_up()
+under the console_sem lock. This will also make the semaphore's
+raw_spinlock become a terminal lock without taking any further locks
+underneath it.
+
+The hrtimer_bases.lock is a raw_spinlock while zone->lock is a
+spinlock. The hrtimer_bases.lock -> zone->lock dependency happens via
+the debug_objects_fill_pool() helper function in the debugobjects code.
+
+  -> #4 (&zone->lock){-.-.}-{2:2}:

+         do_IRQ+0x9a/0xe0
+         do_irq_async+0xf6/0x160
+
+Normally a raw_spinlock to spinlock dependency is not legitimate
+and will be warned if CONFIG_PROVE_RAW_LOCK_NESTING is enabled,
+but debug_objects_fill_pool() is an exception as it explicitly
+allows this dependency for non-PREEMPT_RT kernel without causing
+PROVE_RAW_LOCK_NESTING lockdep splat. As a result, this dependency is
+legitimate and not a bug.
+
+Anyway, semaphore is the only locking primitive left that is still
+using try_to_wake_up() to do wakeup inside critical section, all the
+other locking primitives had been migrated to use wake_q to do wakeup
+outside of the critical section. It is also possible that there are
+other circular locking dependencies involving printk/console_sem or
+other existing/new semaphores lurking somewhere which may show up in
+the future. Let just do the migration now to wake_q to avoid headache
+like this.

+Subject: mdacon: rework dependency list
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 5bbcc7645f4b244ffb5ac6563fbe9d3d42194447 ]
+
+mdacon has roughly the same dependencies as vgacon but expresses them
+as a negative list instead of a positive list, with the only practical
+difference being PowerPC/CHRP, which uses vga16fb instead of vgacon.
+
+The CONFIG_MDA_CONSOLE description advises to only turn it on when vgacon
+is also used because MDA/Hercules-only systems should be using vgacon
+instead, so just change the list to enforce that directly for simplicity.
+
+The probing was broken from 2002 to 2008, this improves on the fix
+that was added then: If vgacon is a loadable module, then mdacon
+cannot be built-in now, and the list of systems that support vgacon

+
+From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
+
+[ Upstream commit c2b96a6818159fba8a3bcc38262da9e77f9b3ec7 ]
+
+In allegro_probe(), the v4l2 device is not unregistered in the error
+path, which results in a memory leak. Fix it by calling
+v4l2_device_unregister() before returning error.

+
+From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
+
+[ Upstream commit 2d8cb9ffe18c2f1e5bd07a19cbce85b26c1d0cf0 ]
+
+If offset end up being high enough, right hand expression in functions
+like sm501_gpio_set() shifted left for that number of bits, may
+not fit in int type.
+
+Just in case, fix that by using BIT() both as an option safe from

+drivers.

+From: Lin Ma <linma@zju.edu.cn>
+
+[ Upstream commit b27055a08ad4b415dcf15b63034f9cb236f7fb40 ]
+
+struct geneve_opt uses 5 bit length for each single option, which
+means every vary size option should be smaller than 128 bytes.
+
+However, all current related Netlink policies cannot promise this
+length condition and the attacker can exploit a exact 128-byte size
+option to *fake* a zero length option and confuse the parsing logic,
+further achieve heap out-of-bounds read.
+
+One example crash log is like below:

+Subject: net: mvpp2: Prevent parser TCAM memory corruption
+
+From: Tobias Waldekranz <tobias@waldekranz.com>
+
+[ Upstream commit 96844075226b49af25a69a1d084b648ec2d9b08d ]
+
+Protect the parser TCAM/SRAM memory, and the cached (shadow) SRAM
+information, from concurrent modifications.
+
+Both the TCAM and SRAM tables are indirectly accessed by configuring
+an index register that selects the row to read or write to. This means
+that operations must be atomic in order to, e.g., avoid spreading
+writes across multiple rows. Since the shadow SRAM array is used to
+find free rows in the hardware table, it must also be protected in
+order to avoid TOCTOU errors where multiple cores allocate the same
+row.
+
+This issue was detected in a situation where `mvpp2_set_rx_mode()` ran
+concurrently on two CPUs. In this particular case the
+MVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the
+classifier unit to drop all incoming unicast - indicated by the
+`rx_classifier_drops` counter.

+Subject: net_sched: skbprio: Remove overly strict queue assertions
+
+From: Cong Wang <xiyou.wangcong@gmail.com>
+
+[ Upstream commit ce8fe975fd99b49c29c42e50f2441ba53112b2e8 ]
+
+In the current implementation, skbprio enqueue/dequeue contains an assertion
+that fails under certain conditions when SKBPRIO is used as a child qdisc under
+TBF with specific parameters. The failure occurs because TBF sometimes peeks at
+packets in the child qdisc without actually dequeuing them when tokens are
+unavailable.
+
+This peek operation creates a discrepancy between the parent and child qdisc
+queue length counters. When TBF later receives a high-priority packet,
+SKBPRIO's queue length may show a different value than what's reflected in its
+internal priority queue tracking, triggering the assertion.
+
+The fix removes this overly strict assertions in SKBPRIO, they are not
+necessary at all.

+Subject: netfilter: nft_tunnel: fix geneve_opt type confusion addition
+
+From: Lin Ma <linma@zju.edu.cn>
+
+[ Upstream commit 1b755d8eb1ace3870789d48fbd94f386ad6e30be ]
+
+When handling multiple NFTA_TUNNEL_KEY_OPTS_GENEVE attributes, the
+parsing logic should place every geneve_opt structure one by one
+compactly. Hence, when deciding the next geneve_opt position, the
+pointer addition should be in units of char *.
+
+However, the current implementation erroneously does type conversion
+before the addition, which will lead to heap out-of-bounds write.

+Subject: netlabel: Fix NULL pointer exception caused by CALIPSO on IPv4
+ sockets
+
+From: Debin Zhu <mowenroot@163.com>
+
+[ Upstream commit 078aabd567de3d63d37d7673f714e309d369e6e2 ]
+
+When calling netlbl_conn_setattr(), addr->sa_family is used
+to determine the function behavior. If sk is an IPv4 socket,
+but the connect function is called with an IPv6 address,
+the function calipso_sock_setattr() is triggered.
+Inside this function, the following code is executed:
+
+sk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL;
+
+Since sk is an IPv4 socket, pinet6 is NULL, leading to a
+null pointer dereference.
+
+This patch fixes the issue by checking if inet6_sk(sk)
+returns a NULL pointer before accessing pinet6.

+
+From: Trond Myklebust <trond.myklebust@hammerspace.com>
+
+[ Upstream commit 47acca884f714f41d95dc654f802845544554784 ]
+
+The amount of looping through the list of delegations is occasionally
+leading to soft lockups. Avoid at least some loops by not requiring the
+NFSv4 state manager to scan for delegations that are marked for
+return-on-close. Instead, either mark them for immediate return (if
+possible) or else leave it up to nfs4_inode_return_delegation_on_close()
+to return them once the file is closed by the application.

+[ Upstream commit 56cf7ef0d490b28fad8f8629fc135c5ab7c9f54e ]
+
+The PCI P2PDMA code will register the CMB block to the memory
+hot-plugging subsystem, which have an alignment requirement. Memory
+blocks that do not satisfy this alignment requirement (usually 2MB) will
+lead to a WARNING from memory hotplugging.
+
+Verify the CMB block's address and size against the alignment and only
+try to send CMB blocks compatible with it to prevent this warning.
+
+Tested on Intel DC D4502 SSD, which has a 512K CMB block that is too
+small for memory hotplugging (thus PCI P2PDMA).

+
+From: Sagi Grimberg <sagi@grimberg.me>
+
+[ Upstream commit 8c1624b63a7d24142a2bbc3a5ee7e95f004ea36e ]
+
+nvme_tcp_poll() may race with the send path error handler because
+it may complete the request while it is actively being polled for
+completion, resulting in a UAF panic [1]:
+
+We should make sure to stop polling when we see an error when
+trying to read from the socket. Hence make sure to propagate the
+error so that the block layer breaks the polling cycle.

+Subject: of: property: Increase NR_FWNODE_REFERENCE_ARGS
+
+From: Zijun Hu <quic_zijuhu@quicinc.com>
+
+[ Upstream commit eb50844d728f11e87491f7c7af15a4a737f1159d ]
+
+Currently, the following two macros have different values:
+
+// The maximal argument count for firmware node reference
+ #define NR_FWNODE_REFERENCE_ARGS      8
+// The maximal argument count for DT node reference
+ #define MAX_PHANDLE_ARGS 16
+
+It may cause firmware node reference's argument count out of range if
+directly assign DT node reference's argument count to firmware's.
+
+drivers/of/property.c:of_fwnode_get_reference_args() is doing the direct
+assignment, so may cause firmware's argument count @args->nargs got out
+of range, namely, in [9, 16].
+
+Fix by increasing NR_FWNODE_REFERENCE_ARGS to 16 to meet DT requirement.
+Will align both macros later to avoid such inconsistency.

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

+
+[ Upstream commit cbf937dcadfd571a434f8074d057b32cd14fbea5 ]
+
+Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to
+avoid use-after-free"), we would free the ASPM link only after the last
+function on the bus pertaining to the given link was removed.
+
+That was too late. If function 0 is removed before sibling function,
+link->downstream would point to free'd memory after.
+
+After above change, we freed the ASPM parent link state upon any function
+removal on the bus pertaining to a given link.
+
+That is too early. If the link is to a PCIe switch with MFD on the upstream
+port, then removing functions other than 0 first would free a link which
+still remains parent_link to the remaining downstream ports.
+
+The resulting GPFs are especially frequent during hot-unplug, because
+pciehp removes devices on the link bus in reverse order.
+
+On that switch, function 0 is the virtual P2P bridge to the internal bus.
+Free exactly when function 0 is removed -- before the parent link is
+obsolete, but after all subordinate links are gone.

+Subject: PCI: Avoid reset when disabled via sysfs
+
+From: Nishanth Aravamudan <naravamudan@nvidia.com>
+
+[ Upstream commit 479380efe1625e251008d24b2810283db60d6fcd ]
+
+After d88f521da3ef ("PCI: Allow userspace to query and set device reset
+mechanism"), userspace can disable reset of specific PCI devices by writing
+an empty string to the sysfs reset_method file.
+
+However, pci_slot_resettable() does not check pci_reset_supported(), which
+means that pci_reset_function() will still reset the device even if
+userspace has disabled all the reset methods.
+
+I was able to reproduce this issue with a vfio device passed to a qemu
+guest, where I had disabled PCI reset via sysfs.
+
+Add an explicit check of pci_reset_supported() in both
+pci_slot_resettable() and pci_bus_resettable() to ensure both the reset
+status and reset execution are bypassed if an administrator disables it for
+a device.

+
+The driver has been mistakenly writing to a read-only (RO)
+configuration space register (PCI_EXP_LNKCAP) to change the
+PCIe link capability.
+
+Although harmless in this case, the proper write destination
+is an internal register that is reflected by PCI_EXP_LNKCAP.
+
+Thus, fix the brcm_pcie_set_gen() function to correctly update
+the link capability.

+[ Upstream commit 527664f738afb6f2c58022cd35e63801e5dc7aec ]
+
+PCIe hotplug can operate in poll mode without interrupt handlers using a
+polling kthread only.  eb34da60edee ("PCI: pciehp: Disable hotplug
+interrupt during suspend") failed to consider that and enables HPIE
+(Hot-Plug Interrupt Enable) unconditionally when resuming the Port.
+
+Only set HPIE if non-poll mode is in use. This makes
+pcie_enable_interrupt() match how pcie_enable_notification() already
+handles HPIE.

+Subject: PCI/portdrv: Only disable pciehp interrupts early when needed
+
+From: Feng Tang <feng.tang@linux.alibaba.com>
+
+[ Upstream commit 9d7db4db19827380e225914618c0c1bf435ed2f5 ]
+
+Firmware developers reported that Linux issues two PCIe hotplug commands in
+very short intervals on an ARM server, which doesn't comply with the PCIe
+spec.  According to PCIe r6.1, sec 6.7.3.2, if the Command Completed event
+is supported, software must wait for a command to complete or wait at
+least 1 second before sending a new command.
+
+In the failure case, the first PCIe hotplug command is from
+get_port_device_capability(), which sends a command to disable PCIe hotplug
+interrupts without waiting for its completion, and the second command comes
+from pcie_enable_notification() of pciehp driver, which enables hotplug
+interrupts again.
+
+Fix this by only disabling the hotplug interrupts when the pciehp driver is
+not enabled.

+Subject: perf python: Check if there is space to copy all the event

+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+[ Upstream commit 89aaeaf84231157288035b366cb6300c1c6cac64 ]
+
+The pyrf_event__new() method copies the event obtained from the perf
+ring buffer to a structure that will then be turned into a python object
+for further consumption, so it copies perf_event.header.size bytes to
+its 'event' member:
+
+  $ pahole -C pyrf_event /tmp/build/perf-tools-next/python/perf.cpython-312-x86_64-linux-gnu.so
+  struct pyrf_event {
+       PyObject                   ob_base;              /*     0    16 */
+       struct evsel *             evsel;                /*    16     8 */
+       struct perf_sample         sample;               /*    24   312 */
+
+       /* XXX last struct has 7 bytes of padding, 2 holes */
+
+       /* --- cacheline 5 boundary (320 bytes) was 16 bytes ago --- */
+       union perf_event           event;                /*   336  4168 */
+
+       /* size: 4504, cachelines: 71, members: 4 */
+       /* member types with holes: 1, total: 2 */
+       /* paddings: 1, sum paddings: 7 */
+       /* last cacheline: 24 bytes */
+  };
+
+  $
+
+It was doing so without checking if the event just obtained has more
+than that space, fix it.
+
+This isn't a proper, final solution, as we need to support larger
+events, but for the time being we at least bounds check and document it.

+Subject: pinctrl: tegra: Set SFIO mode to Mux Register
+
+From: Prathamesh Shete <pshete@nvidia.com>
+
+[ Upstream commit 17013f0acb322e5052ff9b9d0fab0ab5a4bfd828 ]
+
+Tegra devices have an 'sfsel' bit field that determines whether a pin
+operates in SFIO (Special Function I/O) or GPIO mode. Currently,
+tegra_pinctrl_gpio_disable_free() sets this bit when releasing a GPIO.
+
+However, tegra_pinctrl_set_mux() can be called independently in certain
+code paths where gpio_disable_free() is not invoked. In such cases, failing
+to set the SFIO mode could lead to incorrect pin configurations, resulting
+in functional issues for peripherals relying on SFIO.
+
+This patch ensures that whenever set_mux() is called, the SFIO mode is
+correctly set in the Mux Register if the 'sfsel' bit is present. This
+prevents situations where the pin remains in GPIO mode despite being
+configured for SFIO use.

+Subject: PM: sleep: Fix handling devices with direct_complete set on errors
+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+[ Upstream commit 03f1444016b71feffa1dfb8a51f15ba592f94b13 ]
+
+When dpm_suspend() fails, some devices with power.direct_complete set
+may not have been handled by device_suspend() yet, so runtime PM has
+not been disabled for them yet even though power.direct_complete is set.
+
+Since device_resume() expects that runtime PM has been disabled for all
+devices with power.direct_complete set, it will attempt to reenable
+runtime PM for the devices that have not been processed by device_suspend()
+which does not make sense.  Had those devices had runtime PM disabled
+before device_suspend() had run, device_resume() would have inadvertently
+enable runtime PM for them, but this is not expected to happen because
+it would require ->prepare() callbacks to return positive values for
+devices with runtime PM disabled, which would be invalid.
+
+In practice, this issue is most likely benign because pm_runtime_enable()
+will not allow the "disable depth" counter to underflow, but it causes a
+warning message to be printed for each affected device.
+
+To allow device_resume() to distinguish the "direct complete" devices
+that have been processed by device_suspend() from those which have not
+been handled by it, make device_suspend() set power.is_suspended for
+"direct complete" devices.
+
+Next, move the power.is_suspended check in device_resume() before the
+power.direct_complete check in it to make it skip the "direct complete"
+devices that have not been handled by device_suspend().
+
+This change is based on a preliminary patch from Saravana Kannan.

+
+From: Artur Weber <aweber.kernel@gmail.com>
+
+[ Upstream commit 30cc7b0d0e9341d419eb7da15fb5c22406dbe499 ]
+
+The charge input threshold voltage register on the MAX77693 PMIC accepts
+four values: 0x0 for 4.3v, 0x1 for 4.7v, 0x2 for 4.8v and 0x3 for 4.9v.
+Due to an oversight, the driver calculated the values for 4.7v and above
+starting from 0x0, rather than from 0x1 ([(4700000 - 4700000) / 100000]
+gives 0).
+
+Add 1 to the calculation to ensure that 4.7v is converted to a register
+value of 0x1 and that the other two voltages are converted correctly as
+well.

+  ip netns add foo

+  cat /sys/class/infiniband/mlx4_0/hw_counters/*
+
+The panic occurs because of casting the device pointer into an
+ib_device pointer using container_of() in hw_stat_device_show() is
+wrong and leads to a memory corruption.
+
+However the real problem is that hw counters should never been exposed
+outside of the non-init net namespace.
+
+Fix this by saving the index of the corresponding attribute group
+(it might be 1 or 2 depending on the presence of driver-specific
+attributes) and zeroing the pointer to hw_counters group for compat
+devices during the initialization.
+
+With this fix applied hw_counters are not available in a non-init
+net namespace:
+  find /sys/class/infiniband/mlx4_0/ -name hw_counters
+    /sys/class/infiniband/mlx4_0/ports/1/hw_counters
+    /sys/class/infiniband/mlx4_0/ports/2/hw_counters

+Subject: RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow
+
+From: Patrisious Haddad <phaddad@nvidia.com>
+
+[ Upstream commit 5ed3b0cb3f827072e93b4c5b6e2b8106fd7cccbd ]
+
+When cur_qp isn't NULL, in order to avoid fetching the QP from
+the radix tree again we check if the next cqe QP is identical to
+the one we already have.
+
+The bug however is that we are checking if the QP is identical by
+checking the QP number inside the CQE against the QP number inside the
+mlx5_ib_qp, but that's wrong since the QP number from the CQE is from
+FW so it should be matched against mlx5_core_qp which is our FW QP
+number.
+
+Otherwise we could use the wrong QP when handling a CQE which could
+cause the kernel trace below.
+
+This issue is mainly noticeable over QPs 0 & 1, since for now they are
+the only QPs in our driver whereas the QP number inside mlx5_ib_qp
+doesn't match the QP number inside mlx5_core_qp.

+Subject: remoteproc: core: Clear table_sz when rproc_shutdown
+
+From: Peng Fan <peng.fan@nxp.com>
+
+[ Upstream commit efdde3d73ab25cef4ff2d06783b0aad8b093c0e4 ]
+
+There is case as below could trigger kernel dump:
+Use U-Boot to start remote processor(rproc) with resource table
+published to a fixed address by rproc. After Kernel boots up,
+stop the rproc, load a new firmware which doesn't have resource table
+,and start rproc.
+
+When starting rproc with a firmware not have resource table,
+`memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will
+trigger dump, because rproc->cache_table is set to NULL during the last
+stop operation, but rproc->table_sz is still valid.
+
+This issue is found on i.MX8MP and i.MX9.

+actually just one power domain specified there. Otherwise it'll be an
+issue in the dts and we should fail in the regular code path.
+
+This also mirrors the latest changes in the qcom_q6v5_mss driver.

+The calculation of bytes-dropped and bytes_dropped_nested is reversed.

+Subject: riscv: ftrace: Add parentheses in macro definitions of make_call_t0
+ and make_call_ra
+
+From: Juhan Jin <juhan.jin@foxmail.com>
+
+[ Upstream commit 5f1a58ed91a040d4625d854f9bb3dd4995919202 ]
+
+This patch adds parentheses to parameters caller and callee of macros
+make_call_t0 and make_call_ra. Every existing invocation of these two
+macros uses a single variable for each argument, so the absence of the
+parentheses seems okay. However, future invocations might use more
+complex expressions as arguments. For example, a future invocation might
+look like this: make_call_t0(a - b, c, call). Without parentheses in the
+macro definition, the macro invocation expands to:
+
+...
+unsigned int offset = (unsigned long) c - (unsigned long) a - b;
+...
+
+which is clearly wrong.
+
+The use of parentheses ensures arguments are correctly evaluated and
+potentially saves future users of make_call_t0 and make_call_ra debugging
+trouble.

+Subject: sched/deadline: Use online cpus for validating runtime
+
+From: Shrikanth Hegde <sshegde@linux.ibm.com>
+
+[ Upstream commit 14672f059d83f591afb2ee1fff56858efe055e5a ]
+
+The ftrace selftest reported a failure because writing -1 to
+sched_rt_runtime_us returns -EBUSY. This happens when the possible
+CPUs are different from active CPUs.
+
+Active CPUs are part of one root domain, while remaining CPUs are part
+of def_root_domain. Since active cpumask is being used, this results in
+cpus=0 when a non active CPUs is used in the loop.
+
+Fix it by looping over the online CPUs instead for validating the
+bandwidth calculations.

+Subject: sched/smt: Always inline sched_smt_active()
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 09f37f2d7b21ff35b8b533f9ab8cfad2fe8f72f6 ]
+
+sched_smt_active() can be called from noinstr code, so it should always
+be inlined.  The CONFIG_SCHED_SMT version already has __always_inline.
+Do the same for its !CONFIG_SCHED_SMT counterpart.
+
+Fixes the following warning:
+
+  vmlinux.o: error: objtool: intel_idle_ibrs+0x13: call to sched_smt_active() leaves .noinstr.text section

+
+[ Upstream commit 6ae0042f4d3f331e841495eb0a3d51598e593ec2 ]
+
+Subshell evaluations are not exempt from errexit, so if a command is
+not available, `which` will fail and exit the script as a whole.
+This causes the helpful error messages to not be printed if they are
+tacked on using a `$?` comparison.
+
+Resolve the issue by using chains of logical operators, which are not
+subject to the effects of errexit.

+Subject: tunnels: Accept PACKET_HOST in skb_tunnel_check_pmtu().
+
+From: Guillaume Nault <gnault@redhat.com>
+
+[ Upstream commit 8930424777e43257f5bf6f0f0f53defd0d30415c ]
+
+Because skb_tunnel_check_pmtu() doesn't handle PACKET_HOST packets,
+commit 30a92c9e3d6b ("openvswitch: Set the skbuff pkt_type for proper
+pmtud support.") forced skb->pkt_type to PACKET_OUTGOING for
+openvswitch packets that are sent using the OVS_ACTION_ATTR_OUTPUT
+action. This allowed such packets to invoke the
+iptunnel_pmtud_check_icmp() or iptunnel_pmtud_check_icmpv6() helpers
+and thus trigger PMTU update on the input device.
+
+However, this also broke other parts of PMTU discovery. Since these
+packets don't have the PACKET_HOST type anymore, they won't trigger the
+sending of ICMP Fragmentation Needed or Packet Too Big messages to
+remote hosts when oversized (see the skb_in->pkt_type condition in
+__icmp_send() for example).
+
+These two skb->pkt_type checks are therefore incompatible as one
+requires skb->pkt_type to be PACKET_HOST, while the other requires it
+to be anything but PACKET_HOST.
+
+It makes sense to not trigger ICMP messages for non-PACKET_HOST packets
+as these messages should be generated only for incoming l2-unicast
+packets. However there doesn't seem to be any reason for
+skb_tunnel_check_pmtu() to ignore PACKET_HOST packets.
+
+Allow both cases to work by allowing skb_tunnel_check_pmtu() to work on
+PACKET_HOST packets and not overriding skb->pkt_type in openvswitch
+anymore.
+
+Fixes: 30a92c9e3d6b ("openvswitch: Set the skbuff pkt_type for proper pmtud support.")

+Subject: vsock: avoid timeout during connect() if the socket is closing
+
+From: Stefano Garzarella <sgarzare@redhat.com>
+
+[ Upstream commit fccd2b711d9628c7ce0111d5e4938652101ee30a ]
+
+When a peer attempts to establish a connection, vsock_connect() contains
+a loop that waits for the state to be TCP_ESTABLISHED. However, the
+other peer can be fast enough to accept the connection and close it
+immediately, thus moving the state to TCP_CLOSING.
+
+When this happens, the peer in the vsock_connect() is properly woken up,
+but since the state is not TCP_ESTABLISHED, it goes back to sleep
+until the timeout expires, returning -ETIMEDOUT.
+
+If the socket state is TCP_CLOSING, waiting for the timeout is pointless.
+vsock_connect() can return immediately without errors or delay since the
+connection actually happened. The socket will be in a closing state,
+but this is not an issue, and subsequent calls will fail as expected.
+
+We discovered this issue while developing a test that accepts and
+immediately closes connections to stress the transport switch between
+two connect() calls, where the first one was interrupted by a signal
+(see Closes link).

+Subject: watch_queue: fix pipe accounting mismatch
+
+From: Eric Sandeen <sandeen@redhat.com>
+
+[ Upstream commit f13abc1e8e1a3b7455511c4e122750127f6bc9b0 ]
+
+Currently, watch_queue_set_size() modifies the pipe buffers charged to
+user->pipe_bufs without updating the pipe->nr_accounted on the pipe
+itself, due to the if (!pipe_has_watch_queue()) test in
+pipe_resize_ring(). This means that when the pipe is ultimately freed,
+we decrement user->pipe_bufs by something other than what than we had
+charged to it, potentially leading to an underflow. This in turn can
+cause subsequent too_many_pipe_buffers_soft() tests to fail with -EPERM.
+
+To remedy this, explicitly account for the pipe usage in
+watch_queue_set_size() to match the number set via account_pipe_buffers()
+
+(It's unclear why watch_queue_set_size() does not update nr_accounted;
+it may be due to intentional overprovisioning in watch_queue_set_size()?)

+Subject: wifi: iwlwifi: fw: allocate chained SG tables for dump
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+[ Upstream commit 7774e3920029398ad49dc848b23840593f14d515 ]
+
+The firmware dumps can be pretty big, and since we use single
+pages for each SG table entry, even the table itself may end
+up being an order-5 allocation. Build chained tables so that
+we need not allocate a higher-order table here.
+
+This could be improved and cleaned up, e.g. by using the SG
+pool code or simply kvmalloc(), but all of that would require
+also updating the devcoredump first since that frees it all,
+so we need to be more careful. SG pool might also run against
+the CONFIG_ARCH_NO_SG_CHAIN limitation, which is irrelevant
+here.
+
+Also use _devcd_free_sgtable() for the error paths now, much
+simpler especially since it's in two places now.

+Subject: x86/dumpstack: Fix inaccurate unwinding from exception stacks due to
+ misplaced assignment
+
+From: Jann Horn <jannh@google.com>
+
+[ Upstream commit 2c118f50d7fd4d9aefc4533a26f83338b2906b7a ]
+
+Commit:
+
+  2e4be0d011f2 ("x86/show_trace_log_lvl: Ensure stack pointer is aligned, again")
+
+was intended to ensure alignment of the stack pointer; but it also moved
+the initialization of the "stack" variable down into the loop header.
+
+This was likely intended as a no-op cleanup, since the commit
+message does not mention it; however, this caused a behavioral change
+because the value of "regs" is different between the two places.
+
+Originally, get_stack_pointer() used the regs provided by the caller; after
+that commit, get_stack_pointer() instead uses the regs at the top of the
+stack frame the unwinder is looking at. Often, there are no such regs at
+all, and "regs" is NULL, causing get_stack_pointer() to fall back to the
+task's current stack pointer, which is not what we want here, but probably
+happens to mostly work. Other times, the original regs will point to
+another regs frame - in that case, the linear guess unwind logic in
+show_trace_log_lvl() will start unwinding too far up the stack, causing the
+first frame found by the proper unwinder to never be visited, resulting in
+a stack trace consisting purely of guess lines.
+
+Fix it by moving the "stack = " assignment back where it belongs.

+Subject: x86/entry: Fix ORC unwinder for PUSH_REGS with save_ret=1
+
+From: Jann Horn <jannh@google.com>
+
+[ Upstream commit 57e2428f8df8263275344566e02c277648a4b7f1 ]
+
+PUSH_REGS with save_ret=1 is used by interrupt entry helper functions that
+initially start with a UNWIND_HINT_FUNC ORC state.
+
+However, save_ret=1 means that we clobber the helper function's return
+address (and then later restore the return address further down on the
+stack); after that point, the only thing on the stack we can unwind through
+is the IRET frame, so use UNWIND_HINT_IRET_REGS until we have a full
+pt_regs frame.
+
+( An alternate approach would be to move the pt_regs->di overwrite down
+  such that it is the final step of pt_regs setup; but I don't want to
+  rearrange entry code just to make unwinding a tiny bit more elegant. )

+
+The init_task instance of struct task_struct is statically allocated and
+may not contain the full FP state for userspace. As such, limit the copy

+
+Note that the FP state is only needed for userspace, and as such it is
+entirely reasonable for init_task to not contain parts of it.

+
+The CONFIG_EISA menu was cleaned up in 2018, but this inadvertently

+CPUs, long before the first x86-64 products.

+Subject: x86/sgx: Warn explicitly if X86_FEATURE_SGX_LC is not enabled
+
+From: Vladis Dronov <vdronov@redhat.com>
+
+[ Upstream commit 65be5c95d08eedda570a6c888a12384c77fe7614 ]
+
+The kernel requires X86_FEATURE_SGX_LC to be able to create SGX enclaves,
+not just X86_FEATURE_SGX.
+
+There is quite a number of hardware which has X86_FEATURE_SGX but not
+X86_FEATURE_SGX_LC. A kernel running on such hardware does not create
+the /dev/sgx_enclave file and does so silently.
+
+Explicitly warn if X86_FEATURE_SGX_LC is not enabled to properly notify
+users that the kernel disabled the SGX driver.
+
+The X86_FEATURE_SGX_LC, a.k.a. SGX Launch Control, is a CPU feature
+that enables LE (Launch Enclave) hash MSRs to be writable (with
+additional opt-in required in the 'feature control' MSR) when running
+enclaves, i.e. using a custom root key rather than the Intel proprietary
+key for enclave signing.
+
+I've hit this issue myself and have spent some time researching where
+my /dev/sgx_enclave file went on SGX-enabled hardware.

+[ mingo: Made the error message a bit more verbose, and added other cases
+         where the kernel fails to create the /dev/sgx_enclave device node. ]
