+Subject: 6lowpan: iphc: Fix an off-by-one check of array index
+
+From: Colin Ian King <colin.king@canonical.com>
+
+[ Upstream commit 9af417610b6142e826fd1ee8ba7ff3e9a2133a5a ]
+
+The bounds check of id is off-by-one and the comparison should
+be >= rather >. Currently the WARN_ON_ONCE check does not stop
+the out of range indexing of &ldev->ctx.table[id] so also add
+a return path if the bounds are out of range.
+
+Addresses-Coverity: ("Illegal address computation").

+Subject: ARM: dts: meson8: Use a higher default GPU clock frequency
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit 44cf630bcb8c5ec78125805c9447dd5766792224 ]
+
+We are seeing "imprecise external abort (0x1406)" errors during boot
+(which then cause the whole board to hang) on Meson8 (but not Meson8m2).
+These are observed while trying to access the GPU's registers when the
+MALI clock is running at it's default setting of 24MHz. The 3.10 vendor
+kernel uses 318.75MHz as "default" GPU frequency. Using that makes the
+"imprecise external aborts" go away.
+Add the assigned-clocks and assigned-clock-rates properties to also bump
+the MALI clock to 318.75MHz before accessing any of it's registers.
+

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit 514ef1e62d6521c2199d192b1c71b79d2aa21d5a ]
+
+Current PCIe MEM space of size 16 MB is not enough for some combination
+of PCIe cards (e.g. NVMe disk together with ath11k wifi card). ARM Trusted
+Firmware for Armada 3700 platform already assigns 128 MB for PCIe window,
+so extend PCIe MEM space to the end of 128 MB PCIe window which allows to
+allocate more PCIe BARs for more PCIe cards.
+
+Without this change some combination of PCIe cards cannot be used and
+kernel show error messages in dmesg during initialization:
+
+ pci 0000:00:00.0: BAR 8: no space for [mem size 0x01800000]
+ pci 0000:00:00.0: BAR 8: failed to assign [mem size 0x01800000]

+ pci 0000:03:00.0: BAR 0: failed to assign [mem size 0x01000000 64bit]
+
+Due to bugs in U-Boot port for Turris Mox, the second range in Turris Mox
+kernel DTS file for PCIe must start at 16 MB offset. Otherwise U-Boot
+crashes during loading of kernel DTB file. This bug is present only in
+U-Boot code for Turris Mox and therefore other Armada 3700 devices are not
+affected by this bug. Bug is fixed in U-Boot version 2021.07.
+
+To not break booting new kernels on existing versions of U-Boot on Turris
+Mox, use first 16 MB range for IO and second range with rest of PCIe window
+for MEM.

++ * U-Boot port for Turris Mox has a bug which always expects that "ranges" DT property

+
+[ Upstream commit c96ca5604a889a142d6b60889cc6da48498806e9 ]
+
+Hihope boards use Realtek PHY. From the very beginning it use only
+tx delays. However the phy driver commit bbc4d71d63549bcd003
+("net: phy: realtek: fix rtl8211e rx/tx delay config") introduced
+NFS mount failure. Now it needs rx delay inaddition to tx delay
+for NFS mount to work. This patch fixes NFS mount failure issue
+by adding MAC internal rx delay.

+Subject: arm64: dts: renesas: rzg2: Convert EtherAVB to explicit delay
+ handling
+
+From: Geert Uytterhoeven <geert+renesas@glider.be>
+
+[ Upstream commit a5200e63af57d05ed8bf0ffd9a6ffefc40e01e89 ]
+
+Some EtherAVB variants support internal clock delay configuration, which
+can add larger delays than the delays that are typically supported by
+the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
+properties).
+
+Historically, the EtherAVB driver configured these delays based on the
+"rgmii-*id" PHY mode. This was wrong, as these are meant solely for the
+PHY, not for the MAC. Hence properties were introduced for explicit
+configuration of these delays.
+
+Convert the RZ/G2 DTS files from the old to the new scheme:
+ - Add default "rx-internal-delay-ps" and "tx-internal-delay-ps"
+ properties to the SoC .dtsi files, to be overridden by board files
+ where needed,
+ - Convert board files from "rgmii-*id" PHY modes to "rgmii", adding
+ the appropriate "rx-internal-delay-ps" and/or "tx-internal-delay-ps"
+ overrides.
+
+Notes:
+ - RZ/G2E does not support TX internal delay handling.

+From: Curtis Malainey <cujomalainey@chromium.org>
+
+[ Upstream commit f4eeaed04e861b95f1f2c911263f2fcaa959c078 ]
+
+Sparse warnings triggered truncating the IDs of some platform device
+tables. Unfortunately some of the IDs in the match tables were missed
+which breaks audio. The KBL change has been verified to fix audio, the
+CML change was not tested as it was found through grepping the broken
+changes and found to match the same situation in anticipation that it
+should also be fixed.

+Subject: ASoC: Intel: Skylake: Fix module resource and format selection
+
+From: Cezary Rojewski <cezary.rojewski@intel.com>
+
+[ Upstream commit e8b374b649afe756c2470e0e6668022e90bf8518 ]
+
+Module configuration may differ between its instances depending on
+resources required and input and output audio format. Available
+parameters to select from are stored in module resource and interface
+(format) lists. These come from topology, together with description of
+each of pipe's modules.
+
+Ignoring index value provided by topology and relying always on 0th
+entry leads to unexpected module behavior due to under/overbudged
+resources assigned or impropper format selection. Fix by taking entry at
+index specified by topology.

+stuffed on it, I got this message at bootup:
+
+ rt5682 9-001a: Device with ID register 6749 is not rt5682
+
+That's normal/expected, but what wasn't normal was the splat that I
+got after:

+
+[ Upstream commit d3efd26af2e044ff2b48d38bb871630282d77e60 ]

+The probe calls 'wcd9335_setup_irqs()' to enable interrupts on all slave

+This must be undone in the remove function.
+
+Add a 'wcd9335_teardown_irqs()' function that undoes 'wcd9335_setup_irqs()'

+Subject: ASoC: wcd9335: Fix a double irq free in the remove function
+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 7a6a723e98aa45f393e6add18f7309dfffa1b0e2 ]
+
+There is no point in calling 'free_irq()' explicitly for
+'WCD9335_IRQ_SLIMBUS' in the remove function.
+
+The irqs are requested in 'wcd9335_setup_irqs()' using a resource managed
+function (i.e. 'devm_request_threaded_irq()').
+'wcd9335_setup_irqs()' requests all what is defined in the 'wcd9335_irqs'
+structure.
+This structure has only one entry for 'WCD9335_IRQ_SLIMBUS'.
+
+So 'devm_request...irq()' + explicit 'free_irq()' would lead to a double
+free.
+
+Remove the unneeded 'free_irq()' from the remove function.

+kmemleak reported that dev_name() of internally-handled cores were leaked
+on driver unbinding. Let's use device_initialize() to take refcounts for
+them and put_device() to properly free the related stuff.
+
+While looking at it, there's another potential issue for those which should
+be *registered* into driver core. If device_register() failed, we put
+device once and freed bcma_device structures. In bcma_unregister_cores(),
+they're treated as unregistered and we hit both UAF and double-free. That
+smells not good and has also been fixed now.

+Subject: blk-throtl: optimize IOPS throttle for large IO scenarios
+
+From: Chunguang Xu <brookxu@tencent.com>
+
+[ Upstream commit 4f1e9630afe6332de7286820fedd019f19eac057 ]
+
+After patch 54efd50 (block: make generic_make_request handle
+arbitrarily sized bios), the IO through io-throttle may be larger,
+and these IOs may be further split into more small IOs. However,
+IOPS throttle does not seem to be aware of this change, which
+makes the calculation of IOPS of large IOs incomplete, resulting
+in disk-side IOPS that does not meet expectations. Maybe we should
+fix this problem.
+
+We can reproduce it by set max_sectors_kb of disk to 128, set
+blkio.write_iops_throttle to 100, run a dd instance inside blkio
+and use iostat to watch IOPS:
+
+dd if=/dev/zero of=/dev/sdb bs=1M count=1000 oflag=direct
+
+As a result, without this change the average IOPS is 1995, with
+this change the IOPS is 98.

+Subject: block: nbd: add sanity check for first_minor
+
+From: Pavel Skripkin <paskripkin@gmail.com>
+
+[ Upstream commit b1a811633f7321cf1ae2bb76a66805b7720e44c9 ]
+
+Syzbot hit WARNING in internal_create_group(). The problem was in
+too big disk->first_minor.
+
+disk->first_minor is initialized by value, which comes from userspace
+and there wasn't any sanity checks about value correctness. It can cause
+duplicate creation of sysfs files/links, because disk->first_minor will
+be passed to MKDEV() which causes truncation to byte. Since maximum
+minor value is 0xff, let's check if first_minor is correct minor number.
+
+NOTE: the root case of the reported warning was in wrong error handling
+in register_disk(), but we can avoid passing knowingly wrong values to
+sysfs API, because sysfs error messages can confuse users. For example:
+user passed 1048576 as index, but sysfs complains about duplicate
+creation of /dev/block/43:0. It's not obvious how 1048576 becomes 0.
+Log and reproducer for above example can be found on syzkaller bug
+report page.

+Subject: block: return ELEVATOR_DISCARD_MERGE if possible
+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 866663b7b52d2da267b28e12eed89ee781b8fed1 ]
+
+When merging one bio to request, if they are discard IO and the queue
+supports multi-range discard, we need to return ELEVATOR_DISCARD_MERGE
+because both block core and related drivers(nvme, virtio-blk) doesn't
+handle mixed discard io merge(traditional IO merge together with
+discard merge) well.
+
+Fix the issue by returning ELEVATOR_DISCARD_MERGE in this situation,
+so both blk-mq and drivers just need to handle multi-range discard.

+
+[ Upstream commit f41a4b2b5eb7872109723dab8ae1603bdd9d9ec1 ]

+Syzbot hit "task hung" bug in hci_req_sync(). The problem was in
+unreasonable huge inquiry timeout passed from userspace.
+Fix it by adding sanity check for timeout value to hci_inquiry().
+
+Since hci_inquiry() is the only user of hci_req_sync() with user
+controlled timeout value, it makes sense to check timeout value in
+hci_inquiry() and don't touch hci_req_sync().

+Subject: Bluetooth: fix repeated calls to sco_sock_kill
+
+From: Desmond Cheong Zhi Xi <desmondcheongzx@gmail.com>
+
+[ Upstream commit e1dee2c1de2b4dd00eb44004a4bda6326ed07b59 ]
+
+In commit 4e1a720d0312 ("Bluetooth: avoid killing an already killed
+socket"), a check was added to sco_sock_kill to skip killing a socket
+if the SOCK_DEAD flag was set.
+
+This was done after a trace for a use-after-free bug showed that the
+same sock pointer was being killed twice.
+
+Unfortunately, this check prevents sco_sock_kill from running on any
+socket. sco_sock_kill kills a socket only if it's zapped and orphaned,
+however sock_orphan announces that the socket is dead before detaching
+it. i.e., orphaned sockets have the SOCK_DEAD flag set.
+
+To fix this, we remove the check for SOCK_DEAD, and avoid repeated
+calls to sco_sock_kill by removing incorrect calls in:
+
+1. sco_sock_timeout. The socket should not be killed on timeout as
+further processing is expected to be done. For example,
+sco_sock_connect sets the timer then waits for the socket to be
+connected or for an error to be returned.
+
+2. sco_conn_del. This function should clean up resources for the
+connection, but the socket itself should be cleaned up in
+sco_sock_release.
+
+3. sco_sock_close. Calls to sco_sock_close in sco_sock_cleanup_listen
+and sco_sock_release are followed by sco_sock_kill. Hence the
+duplicated call should be removed.
+
+Fixes: 4e1a720d0312 ("Bluetooth: avoid killing an already killed socket")

+An earlier commit replaced using batostr to using %pMR sprintf for the

+Subject: Bluetooth: Move shutdown callback before flushing tx and rx queue
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+[ Upstream commit 0ea53674d07fb6db2dd7a7ec2fdc85a12eb246c2 ]
+
+Commit 0ea9fd001a14 ("Bluetooth: Shutdown controller after workqueues
+are flushed or cancelled") introduced a regression that makes mtkbtsdio
+driver stops working:
+[ 36.593956] Bluetooth: hci0: Firmware already downloaded
+[ 46.814613] Bluetooth: hci0: Execution of wmt command timed out
+[ 46.814619] Bluetooth: hci0: Failed to send wmt func ctrl (-110)
+
+The shutdown callback depends on the result of hdev->rx_work, so we
+should call it before flushing rx_work:
+-> btmtksdio_shutdown()
+ -> mtk_hci_wmt_sync()
+ -> __hci_cmd_send()
+ -> wait for BTMTKSDIO_TX_WAIT_VND_EVT gets cleared
+
+-> btmtksdio_recv_event()
+ -> hci_recv_frame()
+ -> queue_work(hdev->workqueue, &hdev->rx_work)
+ -> clears BTMTKSDIO_TX_WAIT_VND_EVT
+
+So move the shutdown callback before flushing TX/RX queue to resolve the
+issue.

+Subject: bpf: Fix possible out of bound write in narrow load handling
+
+From: Andrey Ignatov <rdna@fb.com>
+
+[ Upstream commit d7af7e497f0308bc97809cc48b58e8e0f13887e1 ]
+
+Fix a verifier bug found by smatch static checker in [0].
+
+This problem has never been seen in prod to my best knowledge. Fixing it
+still seems to be a good idea since it's hard to say for sure whether
+it's possible or not to have a scenario where a combination of
+convert_ctx_access() and a narrow load would lead to an out of bound
+write.
+
+When narrow load is handled, one or two new instructions are added to
+insn_buf array, but before it was only checked that
+
+ cnt >= ARRAY_SIZE(insn_buf)
+
+And it's safe to add a new instruction to insn_buf[cnt++] only once. The
+second try will lead to out of bound write. And this is what can happen
+if `shift` is set.
+
+Fix it by making sure that if the BPF_RSH instruction has to be added in
+addition to BPF_AND then there is enough space for two more instructions
+in insn_buf.
+
+The full report [0] is below:

+
+From: He Fengqing <hefengqing@huawei.com>
+
+[ Upstream commit 75f0fc7b48ad45a2e5736bcf8de26c8872fe8695 ]
+
+In bpf_patch_insn_data(), we first use the bpf_patch_insn_single() to
+insert new instructions, then use adjust_insn_aux_data() to adjust
+insn_aux_data. If the old env->prog have no enough room for new inserted
+instructions, we use bpf_prog_realloc to construct new_prog and free the
+old env->prog.
+
+There have two errors here. First, if adjust_insn_aux_data() return
+ENOMEM, we should free the new_prog. Second, if adjust_insn_aux_data()
+return ENOMEM, bpf_patch_insn_data() will return NULL, and env->prog has
+been freed in bpf_prog_realloc, but we will use it in bpf_check().
+
+So in this patch, we make the adjust_insn_aux_data() never fails. In
+bpf_patch_insn_data(), we first pre-malloc memory for the new
+insn_aux_data, then call bpf_patch_insn_single() to insert new
+instructions, at last call adjust_insn_aux_data() to adjust
+insn_aux_data.

+When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a

+Subject: certs: Trigger creation of RSA module signing key if it's not an RSA
+ key
+
+From: Stefan Berger <stefanb@linux.ibm.com>
+
+[ Upstream commit ea35e0d5df6c92fa2e124bb1b91d09b2240715ba ]
+
+Address a kbuild issue where a developer created an ECDSA key for signing
+kernel modules and then builds an older version of the kernel, when bi-
+secting the kernel for example, that does not support ECDSA keys.
+
+If openssl is installed, trigger the creation of an RSA module signing
+key if it is not an RSA key.

+Subject: cgroup/cpuset: Fix a partition bug with hotplug
+
+From: Waiman Long <longman@redhat.com>
+
+[ Upstream commit 15d428e6fe77fffc3f4fff923336036f5496ef17 ]
+
+In cpuset_hotplug_workfn(), the detection of whether the cpu list
+has been changed is done by comparing the effective cpus of the top
+cpuset with the cpu_active_mask. However, in the rare case that just
+all the CPUs in the subparts_cpus are offlined, the detection fails
+and the partition states are not updated correctly. Fix it by forcing
+the cpus_updated flag to true in this particular case.

+

+
+The cpuset fields that manage partition root state do not strictly

+Subject: CIFS: Fix a potencially linear read overflow
+
+From: Len Baker <len.baker@gmx.com>
+
+[ Upstream commit f980d055a0f858d73d9467bb0b570721bbfcdfb8 ]
+
+strlcpy() reads the entire source buffer first. This read may exceed the
+destination size limit. This is both inefficient and can lead to linear
+read overflows if a source string is not NUL-terminated.
+
+Also, the strnlen() call does not avoid the read overflow in the strlcpy
+function when a not NUL-terminated string is passed.
+
+So, replace this block by a call to kstrndup() that avoids this type of
+overflow and does the same.

+Subject: clk: staging: correct reference to config IOMEM to config HAS_IOMEM
+
+From: Lukas Bulwahn <lukas.bulwahn@gmail.com>
+
+[ Upstream commit cbfa6f33e3a685c329d78e06b0cf1dcb23c9d849 ]
+
+Commit 0a0a66c984b3 ("clk: staging: Specify IOMEM dependency for Xilinx
+Clocking Wizard driver") introduces a dependency on the non-existing config
+IOMEM, which basically makes it impossible to include this driver into any
+build. Fortunately, ./scripts/checkkconfigsymbols.py warns:
+
+IOMEM
+Referencing files: drivers/staging/clocking-wizard/Kconfig
+
+The config for IOMEM support is called HAS_IOMEM. Correct this reference to
+the intended config.

+Subject: clocksource/drivers/sh_cmt: Fix wrong setting if don't request IRQ
+ for clock source channel
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Phong Hoang <phong.hoang.wz@renesas.com>
+
+[ Upstream commit be83c3b6e7b8ff22f72827a613bf6f3aa5afadbb ]
+
+If CMT instance has at least two channels, one channel will be used
+as a clock source and another one used as a clock event device.
+In that case, IRQ is not requested for clock source channel so
+sh_cmt_clock_event_program_verify() might work incorrectly.
+Besides, when a channel is only used for clock source, don't need to
+re-set the next match_value since it should be maximum timeout as
+it still is.
+
+On the other hand, due to no IRQ, total_cycles is not counted up
+when reaches compare match time (timer counter resets to zero),
+so sh_cmt_clocksource_read() returns unexpected value.
+Therefore, use 64-bit clocksoure's mask for 32-bit or 16-bit variants
+will also lead to wrong delta calculation. Hence, this mask should
+correspond to timer counter width, and above function just returns
+the raw value of timer counter register.
+

+Subject: counter: 104-quad-8: Return error when invalid mode during

+
+From: William Breathitt Gray <vilhelm.gray@gmail.com>
+
+[ Upstream commit 728246e8f7269ecd35a2c6e6795323e6d8f48db7 ]
+
+The 104-QUAD-8 only has two count modes where a ceiling value makes
+sense: Range Limit and Modulo-N. Outside of these two modes, setting a
+ceiling value is an invalid operation -- so let's report it as such by
+returning -EINVAL.

+Subject: crypto: omap-sham - clear dma flags only after

+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit fe28140b3393b0ba1eb95cc109f974a7e58b26fd ]
+
+We should not clear FLAGS_DMA_ACTIVE before omap_sham_update_dma_stop() is
+done calling dma_unmap_sg(). We already clear FLAGS_DMA_ACTIVE at the
+end of omap_sham_update_dma_stop().
+
+The early clearing of FLAGS_DMA_ACTIVE is not causing issues as we do not
+need to defer anything based on FLAGS_DMA_ACTIVE currently. So this can be
+applied as clean-up.

+From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
+
+[ Upstream commit 5147f0906d50a9d26f2b8698cd06b5680e9867ff ]
+
+The function adf_dev_init() ignores the error code reported by
+enable_vf2pf_comms(). If the latter fails, e.g. the VF is not compatible
+with the pf, then the load of the VF driver progresses.
+This patch changes adf_dev_init() so that the error code from
+enable_vf2pf_comms() is returned to the caller.

+
+[ Upstream commit b90c1c4d3fa8cd90f4e8245b13564380fd0bfad1 ]
+
+At start and shutdown, VFs notify the PF about their state. These
+notifications are carried out through a message exchange using the PFVF
+protocol.
+
+Function names lead to believe they do perform init or shutdown logic.
+This is to fix the naming to better reflect their purpose.

+
+From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
+
+[ Upstream commit 0a73c762e1eee33a5e5dc0e3488f1b7cd17249b3 ]
+
+The top half of the VF drivers handled only a source at the time.
+If an interrupt for PF2VF and bundle occurred at the same time, the ISR
+scheduled only the bottom half for PF2VF.
+This patch fixes the VF top half so that if both sources of interrupt
+trigger at the same time, both bottom halves are scheduled.
+
+This patch is based on earlier work done by Conor McLoughlin.

+Subject: debugfs: Return error during {full/open}_proxy_open() on rmmod
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Sven Eckelmann <sven@narfation.org>
+
+[ Upstream commit 112cedc8e600b668688eb809bf11817adec58ddc ]
+
+If a kernel module gets unloaded then it printed report about a leak before
+commit 275678e7a9be ("debugfs: Check module state before warning in
+{full/open}_proxy_open()"). An additional check was added in this commit to
+avoid this printing. But it was forgotten that the function must return an
+error in this case because it was not actually opened.
+
+As result, the systems started to crash or to hang when a module was
+unloaded while something was trying to open a file.
+
+Fixes: 275678e7a9be ("debugfs: Check module state before warning in {full/open}_proxy_open()")

+Subject: devlink: Clear whole devlink_flash_notify struct
+
+From: Leon Romanovsky <leonro@nvidia.com>
+
+[ Upstream commit ed43fbac717882165a2a4bd64f7b1f56f7467bb7 ]
+
+The { 0 } doesn't clear all fields in the struct, but tells to the
+compiler to set all fields to zero and doesn't touch any sub-fields
+if they exists.
+
+The {} is an empty initialiser that instructs to fully initialize whole
+struct including sub-fields, which is error-prone for future
+devlink_flash_notify extensions.
+
+Fixes: 6700acc5f1fe ("devlink: collect flash notify params into a struct")

+Subject: drm/gma500: Fix end of loop tests for list_for_each_entry
+
+From: Harshvardhan Jha <harshvardhan.jha@oracle.com>
+
+[ Upstream commit ea9a897b8affa0f7b4c90182b785dded74e434aa ]
+
+The list_for_each_entry() iterator, "connector" in this code, can never be
+NULL. If we exit the loop without finding the correct connector then
+"connector" points invalid memory that is an offset from the list head.
+This will eventually lead to memory corruption and presumably a kernel
+crash.

+dpu_hw_ctl_clear_all_blendstages() clears settings for the few first LMs
+instead of mixers actually used for the CTL. Change it to clear

+Subject: drm/msm/dsi: Fix some reference counted resource leaks
+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 6977cc89c87506ff17e6c05f0e37f46752256e82 ]
+
+'of_find_device_by_node()' takes a reference that must be released when
+not needed anymore.
+This is expected to be done in 'dsi_destroy()'.
+
+However, there are 2 issues in 'dsi_get_phy()'.
+
+First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()'
+returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference
+won't be released in 'dsi_destroy()'.
+
+Secondly, as 'of_find_device_by_node()' already takes a reference, there is
+no need for an additional 'get_device()'.
+
+Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the
+unneeded 'get_device()' to solve both issues.

+
+[ Upstream commit 0c9856e4edcdcac22d65618e8ceff9eb41447880 ]
+
+There is some sort of corner case behavior of the controller,
+which could rarely be triggered at least on i.MX6SX connected
+to 800x480 DPI panel and i.MX8MM connected to DPI->DSI->LVDS
+bridged 1920x1080 panel (and likely on other setups too), where

+itself automatically, i.e. the display image remains shifted.
+
+It seems this problem is known and is due to sporadic underflows

+asserted when this condition occurs.

+
+From: Marek Vasut <marex@denx.de>
+
+[ Upstream commit 9891cb54445bc65bf156bda416b6215048c7f617 ]
+
+In case the DRAM is under high load, the MXSFB FIFO might underflow
+and that causes visible artifacts. This could be triggered on i.MX8MM
+using e.g. "$ memtester 128M" on a device with 1920x1080 panel. The
+first "Stuck Address" test of the memtester will completely corrupt
+the image on the panel and leave the MXSFB FIFO in odd state.
+
+To avoid this underflow, increase number of outstanding requests to
+DRAM from 2 to 16, which is the maximum. This mitigates the issue
+and it can no longer be triggered.

+Subject: EDAC/i10nm: Fix NVDIMM detection
+
+From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>
+
+[ Upstream commit 2294a7299f5e51667b841f63c6d69474491753fb ]
+
+MCDDRCFG is a per-channel register and uses bit{0,1} to indicate
+the NVDIMM presence on DIMM slot{0,1}. Current i10nm_edac driver
+wrongly uses MCDDRCFG as per-DIMM register and fails to detect
+the NVDIMM.
+
+Fix it by reading MCDDRCFG as per-channel register and using its
+bit{0,1} to check whether the NVDIMM is populated on DIMM slot{0,1}.

+
+[ Upstream commit 767f4b620edadac579c9b8b6660761d4285fa6f9 ]
+
+Hypervisors likely do not expose the SMCA feature to the guest and
+loading this module leads to false warnings. This module should not be
+loaded in guests to begin with, but people tend to do so, especially
+when testing kernels in VMs. And then they complain about those false
+warnings.
+
+Do the practical thing and do not load this module when running as a
+guest to avoid all that complaining.

+Subject: fcntl: fix potential deadlock for &fasync_struct.fa_lock
+
+From: Desmond Cheong Zhi Xi <desmondcheongzx@gmail.com>
+
+[ Upstream commit 2f488f698fda820f8e6fa0407630154eceb145d6 ]
+
+There is an existing lock hierarchy of
+&dev->event_lock --> &fasync_struct.fa_lock --> &f->f_owner.lock
+from the following call chain:
+
+ input_inject_event():
+ spin_lock_irqsave(&dev->event_lock,...);
+ input_handle_event():
+ input_pass_values():
+ input_to_handler():
+ evdev_events():
+ evdev_pass_values():
+ spin_lock(&client->buffer_lock);
+ __pass_event():
+ kill_fasync():
+ kill_fasync_rcu():
+ read_lock(&fa->fa_lock);
+ send_sigio():
+ read_lock_irqsave(&fown->lock,...);
+
+&dev->event_lock is HARDIRQ-safe, so interrupts have to be disabled
+while grabbing &fasync_struct.fa_lock, otherwise we invert the lock
+hierarchy. However, since kill_fasync which calls kill_fasync_rcu is
+an exported symbol, it may not necessarily be called with interrupts
+disabled.
+
+As kill_fasync_rcu may be called with interrupts disabled (for
+example, in the call chain above), we replace calls to
+read_lock/read_unlock on &fasync_struct.fa_lock in kill_fasync_rcu
+with read_lock_irqsave/read_unlock_irqrestore.

+Subject: firmware: fix theoretical UAF race with firmware cache and resume
+
+From: Zhen Lei <thunder.leizhen@huawei.com>
+
+[ Upstream commit 3ecc8cb7c092b2f50e21d2aaaae35b8221ee7214 ]
+
+This race was discovered when I carefully analyzed the code to locate
+another firmware-related UAF issue. It can be triggered only when the
+firmware load operation is executed during suspend. This possibility is
+almost impossible because there are few firmware load and suspend actions
+in the actual environment.
+
+ CPU0 CPU1
+__device_uncache_fw_images(): assign_fw():
+ fw_cache_piggyback_on_request()
+ <----- P0
+ spin_lock(&fwc->name_lock);
+ ...
+ list_del(&fce->list);
+ spin_unlock(&fwc->name_lock);
+
+ uncache_firmware(fce->name);
+ <----- P1
+ kref_get(&fw_priv->ref);
+
+If CPU1 is interrupted at position P0, the new 'fce' has been added to the
+list fwc->fw_names by the fw_cache_piggyback_on_request(). In this case,
+CPU0 executes __device_uncache_fw_images() and will be able to see it when
+it traverses list fwc->fw_names. Before CPU1 executes kref_get() at P1, if
+CPU0 further executes uncache_firmware(), the count of fw_priv->ref may
+decrease to 0, causing fw_priv to be released in advance.
+
+Move kref_get() to the lock protection range of fwc->name_lock to fix it.

+[ Upstream commit 1e7c57355a3bc617fc220234889e49fe722a6305 ]
+
+When unbinding the firmware device we need to make sure it has no
+consumers left. Otherwise we'd leave them with a firmware handle
+pointing at freed memory.
+
+Keep a reference count of all consumers and introduce rpi_firmware_put()
+which will permit automatically decrease the reference count upon
+unbinding consumer drivers.

+Subject: gfs2: init system threads before freeze lock
+
+From: Bob Peterson <rpeterso@redhat.com>
+
+[ Upstream commit a28dc123fa66ba7f3eca7cffc4b01d96bfd35c27 ]
+
+Patch 96b1454f2e ("gfs2: move freeze glock outside the make_fs_rw and _ro
+functions") changed the gfs2 mount sequence so that it holds the freeze
+lock before calling gfs2_make_fs_rw. Before this patch, gfs2_make_fs_rw
+called init_threads to initialize the quotad and logd threads. That is a
+problem if the system needs to withdraw due to IO errors early in the
+mount sequence, for example, while initializing the system statfs inode:
+
+1. An IO error causes the statfs glock to not sync properly after
+ recovery, and leaves items on the ail list.
+2. The leftover items on the ail list causes its do_xmote call to fail,
+ which makes it want to withdraw. But since the glock code cannot
+ withdraw (because the withdraw sequence uses glocks) it relies upon
+ the logd daemon to initiate the withdraw.
+3. The withdraw can never be performed by the logd daemon because all
+ this takes place before the logd daemon is started.
+
+This patch moves function init_threads from super.c to ops_fstype.c
+and it changes gfs2_fill_super to start its threads before holding the
+freeze lock, and if there's an error, stop its threads after releasing
+it. This allows the logd to run unblocked by the freeze lock. Thus,
+the logd daemon can perform its withdraw sequence properly.
+
+Fixes: 96b1454f2e8e ("gfs2: move freeze glock outside the make_fs_rw and _ro functions")

+Subject: hrtimer: Avoid double reprogramming in __hrtimer_start_range_ns()
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+[ Upstream commit 627ef5ae2df8eeccb20d5af0e4cfa4df9e61ed28 ]
+
+If __hrtimer_start_range_ns() is invoked with an already armed hrtimer then
+the timer has to be canceled first and then added back. If the timer is the
+first expiring timer then on removal the clockevent device is reprogrammed
+to the next expiring timer to avoid that the pending expiry fires needlessly.
+
+If the new expiry time ends up to be the first expiry again then the clock
+event device has to reprogrammed again.
+
+Avoid this by checking whether the timer is the first to expire and in that
+case, keep the timer on the current CPU and delay the reprogramming up to
+the point where the timer has been enqueued again.

+
+From: Sergey Shtylyov <s.shtylyov@omp.ru>
+
+[ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ]
+
+The driver overrides the error codes returned by platform_get_irq() to
+-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
+permanently instead of the deferred probing. Switch to propagating the
+error codes upstream.

+
+[ Upstream commit 661e8a88e8317eb9ffe69c69d6cb4876370fe7e2 ]
+
+Iff platform_get_irq() returns 0 for the main IRQ, the driver's probe()
+method will return 0 early (as if the method's call was successful).
+Let's consider IRQ0 valid for simplicity -- devm_request_irq() can always
+override that decision...

+Subject: i40e: improve locking of mac_filter_hash
+
+From: Stefan Assmann <sassmann@kpanic.de>
+
+[ Upstream commit 8b4b06919fd66caf49fdf4fe59f9d6312cf7956d ]
+
+i40e_config_vf_promiscuous_mode() calls
+i40e_getnum_vf_vsi_vlan_filters() without acquiring the
+mac_filter_hash_lock spinlock.
+
+This is unsafe because mac_filter_hash may get altered in another thread
+while i40e_getnum_vf_vsi_vlan_filters() traverses the hashes.
+
+Simply adding the spinlock in i40e_getnum_vf_vsi_vlan_filters() is not
+possible as it already gets called in i40e_get_vlan_list_sync() with the
+spinlock held. Therefore adding a wrapper that acquires the spinlock and
+call the correct function where appropriate.

+Subject: ice: Only lock to update netdev dev_addr
+
+From: Brett Creeley <brett.creeley@intel.com>
+
+[ Upstream commit b357d9717be7f95fde2c6c4650b186a995b71e59 ]
+
+commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync
+list") introduced calls to netif_addr_lock_bh() and
+netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is
+fine since the driver is updated the netdev's dev_addr, but since this
+is a spinlock, the driver cannot sleep when the lock is held.
+Unfortunately the functions to add/delete MAC filters depend on a mutex.
+This was causing a trace with the lock debug kernel config options
+enabled when changing the mac address via iproute.

+Subject: ipv4: make exception cache less predictible
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 67d6d681e15b578c1725bad8ad079e05d1c48a8e ]
+
+Even after commit 6457378fe796 ("ipv4: use siphash instead of Jenkins in
+fnhe_hashfun()"), an attacker can still use brute force to learn
+some secrets from a victim linux host.
+
+One way to defeat these attacks is to make the max depth of the hash
+table bucket a random value.
+
+Before this patch, each bucket of the hash table used to store exceptions
+could contain 6 items under attack.
+
+After the patch, each bucket would contains a random number of items,
+between 6 and 10. The attacker can no longer infer secrets.
+
+This is slightly increasing memory size used by the hash table,
+by 50% in average, we do not expect this to be a problem.
+
+This patch is more complex than the prior one (IPv6 equivalent),
+because IPv4 was reusing the oldest entry.
+Since we need to be able to evict more than one entry per
+update_or_create_fnhe() call, I had to replace
+fnhe_oldest() with fnhe_remove_oldest().
+
+Also note that we will queue extra kfree_rcu() calls under stress,
+which hopefully wont be a too big issue.

+Subject: irqchip/gic-v3: Fix priority comparison when non-secure priorities
+ are used
+
+From: Chen-Yu Tsai <wenst@chromium.org>
+
+[ Upstream commit 8d474deaba2c4dd33a5e2f5be82e6798ffa6b8a5 ]
+
+When non-secure priorities are used, compared to the raw priority set,
+the value read back from RPR is also right-shifted by one and the
+highest bit set.
+
+Add a macro to do the modifications to the raw priority when doing the
+comparison against the RPR value. This corrects the pseudo-NMI behavior
+when non-secure priorities in the GIC are used. Tested on 5.10 with
+the "IPI as pseudo-NMI" series [1] applied on MT8195.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit 28ce50f8d96ec9035f60c9348294ea26b94db944 ]
+
+Currently iocharset=utf8 mount option is broken. To use UTF-8 as iocharset,
+it is required to use utf8 mount option.
+
+Fix iocharset=utf8 mount option to use be equivalent to the utf8 mount
+option.
+
+If UTF-8 as iocharset is used then s_nls_iocharset is set to NULL. So
+simplify code around, remove s_utf8 field as to distinguish between UTF-8
+and non-UTF-8 it is needed just to check if s_nls_iocharset is set to NULL
+or not.

+Subject: iwlwifi: skip first element in the WTAS ACPI table
+
+From: Abhishek Naik <abhishek.naik@intel.com>
+
+[ Upstream commit 19426d54302e199b3fd2d575f926a13af66be2b9 ]
+
+By mistake we were considering the first element of the WTAS wifi
+package as part of the data we want to rid, but that element is the wifi
+package signature (always 0x07), so it should be skipped.
+
+Change the code to read the data starting from element 1 instead.

+Subject: leds: trigger: audio: Add an activate callback to ensure the initial
+ brightness is set
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 64f67b5240db79eceb0bd57dae8e591fd3103ba0 ]
+
+Some 2-in-1s with a detachable (USB) keyboard(dock) have mute-LEDs in
+the speaker- and/or mic-mute keys on the keyboard.
+
+Examples of this are the Lenovo Thinkpad10 tablet (with its USB kbd-dock)
+and the HP x2 10 series.
+
+The detachable nature of these keyboards means that the keyboard and
+thus the mute LEDs may show up after the user (or userspace restoring
+old mixer settings) has muted the speaker and/or mic.
+
+Current LED-class devices with a default_trigger of "audio-mute" or
+"audio-micmute" initialize the brightness member of led_classdev with
+ledtrig_audio_get() before registering the LED.
+
+This makes the software state after attaching the keyboard match the
+actual audio mute state, e.g. cat /sys/class/leds/foo/brightness will
+show the right value.
+
+But before this commit nothing was actually calling the led_classdev's
+brightness_set[_blocking] callback so the value returned by
+ledtrig_audio_get() was never actually being sent to the hw, leading
+to the mute LEDs staying in their default power-on state, after
+attaching the keyboard, even if ledtrig_audio_get() returned a different
+state.
+
+This could be fixed by having the individual LED drivers call
+brightness_set[_blocking] themselves after registering the LED,
+but this really is something which should be done by a led-trigger
+activate callback.
+
+Add an activate callback for this, fixing the issue of the
+mute LEDs being out of sync after (re)attaching the keyboard.

+Subject: lib/mpi: use kcalloc in mpi_resize
+
+From: Hongbo Li <herberthbli@tencent.com>
+
+[ Upstream commit b6f756726e4dfe75be1883f6a0202dcecdc801ab ]
+
+We should set the additional space to 0 in mpi_resize().
+So use kcalloc() instead of kmalloc_array().
+
+In lib/mpi/ec.c:
+/****************
+ * Resize the array of A to NLIMBS. the additional space is cleared
+ * (set to 0) [done by m_realloc()]
+ */
+int mpi_resize(MPI a, unsigned nlimbs)
+
+Like the comment of kernel's mpi_resize() said, the additional space
+need to be set to 0, but when a->d is not NULL, it does not set.
+
+The kernel's mpi lib is from libgcrypt, the mpi resize in libgcrypt
+is _gcry_mpi_resize() which set the additional space to 0.
+
+This bug may cause mpi api which use mpi_resize() get wrong result
+under the condition of using the additional space without initiation.
+If this condition is not met, the bug would not be triggered.
+Currently in kernel, rsa, sm2 and dh use mpi lib, and they works well,
+so the bug is not triggered in these cases.
+
+add_points_edwards() use the additional space directly, so it will
+get a wrong result.

+Subject: lkdtm: replace SCSI_DISPATCH_CMD with SCSI_QUEUE_RQ
+
+From: Kevin Mitchell <kevmitch@arista.com>
+
+[ Upstream commit d1f278da6b11585f05b2755adfc8851cbf14a1ec ]
+
+When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
+compilers (i.e., at least gcc 8.4.0) decided to compile this
+inline. This is a problem for lkdtm.ko, which inserted a kprobe
+on this function for the SCSI_DISPATCH_CMD crashpoint.
+
+Move this crashpoint one function up the call chain to
+scsi_queue_rq. Though this is also a static function, it should never be
+inlined because it is assigned as a structure entry. Therefore,
+kprobe_register should always be able to find it.
+

+
+From: Benjamin Coddington <bcodding@redhat.com>
+
+[ Upstream commit cd2d644ddba183ec7b451b7c20d5c7cc06fcf0d7 ]
+
+After calling vfs_test_lock() the pointer to a conflicting lock can be
+returned, and that lock is not guarunteed to be owned by nlm. In that
+case, we cannot cast it to struct nlm_lockowner. Instead return the pid
+of that conflicting lock.

+
+[ Upstream commit d8bbd97ad0b99a9394f2cd8410b884c48e218cf0 ]
+
+If CONFIG_DEBUG_LOCK_ALLOC=y is enabled then local_lock_t has an 'owner'
+member which is checked for consistency, but nothing initialized it to
+zero explicitly.
+
+The static initializer does so implicit, and the run time allocated per CPU

+
+[ Upstream commit 048661a1f963e9517630f080687d48af79ed784c ]
+
+Yanfei reported that setting HANDOFF should not depend on recomputing
+@first, only on @first state. Which would then give:
+
+ if (ww_ctx || !first)
+ first = __mutex_waiter_is_first(lock, &waiter);
+ if (first)
+ __mutex_set_flag(lock, MUTEX_FLAG_HANDOFF);
+
+But because 'ww_ctx || !first' is basically 'always' and the test for
+first is relatively cheap, omit that first branch entirely.

+Subject: m68k: Fix invalid RMW_INSNS on CPUs that lack CAS
+
+From: Geert Uytterhoeven <geert@linux-m68k.org>
+
+[ Upstream commit 2189e928b62e91d8efbc9826ae7c0968f0d55790 ]
+
+When enabling CONFIG_RMW_INSNS in e.g. a Coldfire build:
+
+ {standard input}:3068: Error: invalid instruction for this architecture; needs 68020 or higher (68020 [68k, 68ec020], 68030 [68ec030], 68040 [68ec040], 68060 [68ec060]) -- statement `casl %d4,%d0,(%a6)' ignored
+
+Fix this by (a) adding a new config symbol to track if support for any
+CPU that lacks the CAS instruction is enabled, and (b) making
+CONFIG_RMW_INSNS depend on the new symbol not being set.

+
+From: Dongliang Mu <mudongliangabcd@gmail.com>
+
+[ Upstream commit 131ae388b88e3daf4cb0721ed4b4cb8bfc201465 ]
+
+In dvb_usb_i2c_init, if i2c_add_adapter fails, it only prints an error
+message, and then continues to set DVB_USB_STATE_I2C. This affects the
+logic of dvb_usb_i2c_exit, which leads to that, the deletion of i2c_adap
+even if the i2c_add_adapter fails.
+
+Fix this by returning at the failure of i2c_add_adapter and then move
+dvb_usb_i2c_exit out of the error handling code of dvb_usb_i2c_init.

+Subject: media: em28xx-input: fix refcount bug in em28xx_usb_disconnect
+
+From: Dongliang Mu <mudongliangabcd@gmail.com>
+
+[ Upstream commit 6fa54bc713c262e1cfbc5613377ef52280d7311f ]
+
+If em28xx_ir_init fails, it would decrease the refcount of dev. However,
+in the em28xx_ir_fini, when ir is NULL, it goes to ref_put and decrease
+the refcount of dev. This will lead to a refcount bug.
+
+Fix this bug by removing the kref_put in the error handling code
+of em28xx_ir_init.
+
+refcount_t: underflow; use-after-free.

+[ Upstream commit 6f5885a7750545973bf1a942d2f0f129aef0aa06 ]
+
+In go7007_alloc() kzalloc() is used for struct go7007
+allocation. It means that there is no need in zeroing
+any members, because kzalloc will take care of it.
+
+Removing these reduntant initialization steps increases
+execution speed a lot:

+ After:
+ + 29.595 us | go7007_alloc();

+Subject: media: rockchip/rga: fix error handling in probe
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit e58430e1d4fd01b74475d2fbe2e25b5817b729a9 ]
+
+There are a few bugs in this code. 1) No checks for whether
+dma_alloc_attrs() or __get_free_pages() failed. 2) If
+video_register_device() fails it doesn't clean up the dma attrs or the
+free pages. 3) The video_device_release() function frees "vfd" which
+leads to a use after free on the next line. The call to
+video_unregister_device() is not required so I have just removed that.

+Subject: media: venus: venc: Fix potential null pointer dereference on pointer
+ fmt
+
+From: Colin Ian King <colin.king@canonical.com>
+
+[ Upstream commit 09ea9719a423fc675d40dd05407165e161ea0c48 ]
+
+Currently the call to find_format can potentially return a NULL to
+fmt and the nullpointer is later dereferenced on the assignment of
+pixmp->num_planes = fmt->num_planes. Fix this by adding a NULL pointer
+check and returning NULL for the failure case.

+Subject: mm/swap: consider max pages in iomap_swapfile_add_extent
+
+From: Xu Yu <xuyu@linux.alibaba.com>
+
+[ Upstream commit 36ca7943ac18aebf8aad4c50829eb2ea5ec847df ]
+
+When the max pages (last_page in the swap header + 1) is smaller than
+the total pages (inode size) of the swapfile, iomap_swapfile_activate
+overwrites sis->max with total pages.
+
+However, frontswap_map is a swap page state bitmap allocated using the
+initial sis->max page count read from the swap header. If swapfile
+activation increases sis->max, it's possible for the frontswap code to
+walk off the end of the bitmap, thereby corrupting kernel memory.
+
+[djwong: modify the description a bit; the original paragraph reads:
+
+"However, frontswap_map is allocated using max pages. When test and clear
+the sis offset, which is larger than max pages, of frontswap_map in
+__frontswap_invalidate_page(), neighbors of frontswap_map may be
+overwritten, i.e., slab is polluted."
+
+Note also that this bug resulted in a behavioral change: activating a
+swap file that was formatted and later extended results in all pages
+being activated, not the number of pages recorded in the swap header.]
+
+This fixes the issue by considering the limitation of max pages of swap
+info in iomap_swapfile_add_extent().
+
+To reproduce the case, compile kernel with slub RED ZONE, then run test:
+$ sudo stress-ng -a 1 -x softlockup,resources -t 72h --metrics --times \
+ --verify -v -Y /root/tmpdir/stress-ng/stress-statistic-12.yaml \
+ --log-file /root/tmpdir/stress-ng/stress-logfile-12.txt \
+ --temp-path /root/tmpdir/stress-ng/
+
+We'll get the error log as below:

+Subject: net/mlx5e: Block LRO if firmware asks for tunneled LRO
+
+From: Maxim Mikityanskiy <maximmi@nvidia.com>
+
+[ Upstream commit 26ab7b384525ccfa678c518577f7f0d841209c8b ]
+
+This commit does a cleanup in LRO configuration.
+
+LRO is a parameter of an RQ, but its state is changed by modifying a TIR
+related to the RQ.
+
+The current status: LRO for tunneled packets is not supported in the
+driver, inner TIRs may enable LRO on creation, but LRO status of inner
+TIRs isn't changed in mlx5e_modify_tirs_lro(). This is inconsistent, but
+as long as the firmware doesn't declare support for tunneled LRO, it
+works, because the same RQs are shared between the inner and outer TIRs.
+
+This commit does two fixes:
+
+1. If the firmware has the tunneled LRO capability, LRO is blocked
+altogether, because it's not possible to block it for inner TIRs only,
+when the same RQs are shared between inner and outer TIRs, and the
+driver won't be able to handle tunneled LRO traffic.
+
+2. mlx5e_modify_tirs_lro() is patched to modify LRO state for all TIRs,
+including inner ones, because all TIRs related to an RQ should agree on
+their LRO state.
+
+Fixes: 7b3722fa9ef6 ("net/mlx5e: Support RSS for GRE tunneled packets")

+Subject: net/mlx5e: Prohibit inner indir TIRs in IPoIB
+
+From: Maxim Mikityanskiy <maximmi@nvidia.com>
+
+[ Upstream commit 9c43f3865c2a03be104f1c1d5e9129c2a2bdba88 ]
+
+TIR's rx_hash_field_selector_inner can be enabled only when
+tunneled_offload_en = 1. tunneled_offload_en is filled according to the
+tunneled_offload_en field in struct mlx5e_params, which is false in the
+IPoIB profile. On the other hand, the IPoIB profile passes inner_ttc =
+true to mlx5e_create_indirect_tirs, which potentially allows the latter
+function to attempt to create inner indirect TIRs without having
+tunneled_offload_en set.
+
+This commit prohibits this behavior by passing inner_ttc = false to
+mlx5e_create_indirect_tirs. The latter function won't attempt to create
+inner indirect TIRs.
+
+As inner indirect TIRs are not created in the IPoIB profile (this commit
+blocks it explicitly, and even before they would have failed to be
+created), the call to mlx5e_create_inner_ttc_table in
+mlx5i_create_flow_steering is a no-op and can be removed.
+
+Fixes: 46dc933cee82 ("net/mlx5e: Provide explicit directive if to create inner indirect tirs")
+Fixes: 458821c72bd0 ("net/mlx5e: IPoIB, Add inner TTC table to IPoIB flow steering")

+Subject: net: qualcomm: fix QCA7000 checksum handling
+
+From: Stefan Wahren <stefan.wahren@i2se.com>
+
+[ Upstream commit 429205da6c834447a57279af128bdd56ccd5225e ]
+
+Based on tests the QCA7000 doesn't support checksum offloading. So assume
+ip_summed is CHECKSUM_NONE and let the kernel take care of the checksum
+handling. This fixes data transfer issues in noisy environments.

+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit c66070125837900163b81a03063ddd657a7e9bfb ]
+
+The reference counting issue happens in one exception handling path of
+cbq_change_class(). When failing to get tcf_block, the function forgets
+to decrease the refcount of "rtab" increased by qdisc_put_rtab(),
+causing a refcount leak.
+
+Fix this issue by jumping to "failure" label when get tcf_block failed.

+
+[ Upstream commit da9f2150684ea684a7ddd6d7f0e38b2bdf43dcd8 ]
+
+It is inconsistent to return PCI_D0 from pci_target_state() instead
+of the original target state if 'wakeup' is true and the device
+cannot signal PME from D0.
+
+This only happens when the device cannot signal PME from the original
+target state and any shallower power states (including D0) and that
+case is effectively equivalent to the one in which PME singaling is
+not supported at all. Since the original target state is returned in
+the latter case, make the function do that in the former one too.

+Subject: PCI: PM: Enable PME if it can be signaled from D3cold
+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+[ Upstream commit 0e00392a895c95c6d12d42158236c8862a2f43f2 ]
+
+PME signaling is only enabled by __pci_enable_wake() if the target
+device can signal PME from the given target power state (to avoid
+pointless reconfiguration of the device), but if the hierarchy above
+the device goes into D3cold, the device itself will end up in D3cold
+too, so if it can signal PME from D3cold, it should be enabled to
+do so in __pci_enable_wake().
+
+[Note that if the device does not end up in D3cold and it cannot
+ signal PME from the original target power state, it will not signal
+ PME, so in that case the behavior does not change.]

+Subject: PM: cpu: Make notifier chain use a raw_spinlock_t
+
+From: Valentin Schneider <valentin.schneider@arm.com>
+
+[ Upstream commit b2f6662ac08d0e7c25574ce53623c71bdae9dd78 ]
+
+Invoking atomic_notifier_chain_notify() requires acquiring a spinlock_t,
+which can block under CONFIG_PREEMPT_RT. Notifications for members of the
+cpu_pm notification chain will be issued by the idle task, which can never
+block.
+
+Making *all* atomic_notifiers use a raw_spinlock is too big of a hammer, as
+only notifications issued by the idle task are problematic.
+
+Special-case cpu_pm_notifier_chain by kludging a raw_notifier and
+raw_spinlock_t together, matching the atomic_notifier behavior with a
+raw_spinlock_t.

+Subject: PM: EM: Increase energy calculation precision
+
+From: Lukasz Luba <lukasz.luba@arm.com>
+
+[ Upstream commit 7fcc17d0cb12938d2b3507973a6f93fc9ed2c7a1 ]
+
+The Energy Model (EM) provides useful information about device power in
+each performance state to other subsystems like: Energy Aware Scheduler
+(EAS). The energy calculation in EAS does arithmetic operation based on
+the EM em_cpu_energy(). Current implementation of that function uses
+em_perf_state::cost as a pre-computed cost coefficient equal to:
+cost = power * max_frequency / frequency.
+The 'power' is expressed in milli-Watts (or in abstract scale).
+
+There are corner cases when the EAS energy calculation for two Performance
+Domains (PDs) return the same value. The EAS compares these values to
+choose smaller one. It might happen that this values are equal due to
+rounding error. In such scenario, we need better resolution, e.g. 1000
+times better. To provide this possibility increase the resolution in the
+em_perf_state::cost for 64-bit architectures. The cost of increasing
+resolution on 32-bit is pretty high (64-bit division) and is not justified
+since there are no new 32bit big.LITTLE EAS systems expected which would
+benefit from this higher resolution.
+
+This patch allows to avoid the rounding to milli-Watt errors, which might
+occur in EAS energy estimation for each PD. The rounding error is common
+for small tasks which have small utilization value.
+
+There are two places in the code where it makes a difference:
+1. In the find_energy_efficient_cpu() where we are searching for
+best_delta. We might suffer there when two PDs return the same result,
+like in the example below.
+
+Scenario:
+Low utilized system e.g. ~200 sum_util for PD0 and ~220 for PD1. There
+are quite a few small tasks ~10-15 util. These tasks would suffer for
+the rounding error. These utilization values are typical when running games
+on Android. One of our partners has reported 5..10mA less battery drain
+when running with increased resolution.
+
+Some details:
+We have two PDs: PD0 (big) and PD1 (little)
+Let's compare w/o patch set ('old') and w/ patch set ('new')
+We are comparing energy w/ task and w/o task placed in the PDs
+
+a) 'old' w/o patch set, PD0
+task_util = 13
+cost = 480
+sum_util_w/o_task = 215
+sum_util_w_task = 228
+scale_cpu = 1024
+energy_w/o_task = 480 * 215 / 1024 = 100.78 => 100
+energy_w_task = 480 * 228 / 1024 = 106.87 => 106
+energy_diff = 106 - 100 = 6
+(this is equal to 'old' PD1's energy_diff in 'c)')
+
+b) 'new' w/ patch set, PD0
+task_util = 13
+cost = 480 * 1000 = 480000
+sum_util_w/o_task = 215
+sum_util_w_task = 228
+energy_w/o_task = 480000 * 215 / 1024 = 100781
+energy_w_task = 480000 * 228 / 1024 = 106875
+energy_diff = 106875 - 100781 = 6094
+(this is not equal to 'new' PD1's energy_diff in 'd)')
+
+c) 'old' w/o patch set, PD1
+task_util = 13
+cost = 160
+sum_util_w/o_task = 283
+sum_util_w_task = 293
+scale_cpu = 355
+energy_w/o_task = 160 * 283 / 355 = 127.55 => 127
+energy_w_task = 160 * 296 / 355 = 133.41 => 133
+energy_diff = 133 - 127 = 6
+(this is equal to 'old' PD0's energy_diff in 'a)')
+
+d) 'new' w/ patch set, PD1
+task_util = 13
+cost = 160 * 1000 = 160000
+sum_util_w/o_task = 283
+sum_util_w_task = 293
+scale_cpu = 355
+energy_w/o_task = 160000 * 283 / 355 = 127549
+energy_w_task = 160000 * 296 / 355 = 133408
+energy_diff = 133408 - 127549 = 5859
+(this is not equal to 'new' PD0's energy_diff in 'b)')
+
+2. Difference in the 6% energy margin filter at the end of
+find_energy_efficient_cpu(). With this patch the margin comparison also
+has better resolution, so it's possible to have better task placement
+thanks to that.

+Subject: posix-cpu-timers: Force next expiration recalc after itimer reset
+
+From: Frederic Weisbecker <frederic@kernel.org>
+
+[ Upstream commit 406dd42bd1ba0c01babf9cde169bb319e52f6147 ]
+
+When an itimer deactivates a previously armed expiration, it simply doesn't
+do anything. As a result the process wide cputime counter keeps running and
+the tick dependency stays set until it reaches the old ghost expiration
+value.
+
+This can be reproduced with the following snippet:
+
+ void trigger_process_counter(void)
+ {
+ struct itimerval n = {};
+
+ n.it_value.tv_sec = 100;
+ setitimer(ITIMER_VIRTUAL, &n, NULL);
+ n.it_value.tv_sec = 0;
+ setitimer(ITIMER_VIRTUAL, &n, NULL);
+ }
+
+Fix this with resetting the relevant base expiration. This is similar to
+disarming a timer.

+Subject: power: supply: smb347-charger: Add missing pin control activation
+
+From: Dmitry Osipenko <digetx@gmail.com>
+
+[ Upstream commit efe2175478d5237949e33c84d9a722fc084b218c ]
+
+Pin control needs to be activated by setting the enable bit, otherwise
+hardware rejects all pin changes. Previously this stayed unnoticed on
+Nexus 7 because pin control was enabled by default after rebooting from
+downstream kernel, which uses driver that enables the bit and charger
+registers are non-volatile until power supply (battery) is disconnected.
+Configure the pin control enable bit. This fixes the potentially
+never-enabled charging on devices that use pin control.

+
+[ Upstream commit a649d25dcc671a33b9cc3176411920fdc5fbd98e ]
+
+This commit adds a number of lockdep_assert_irqs_disabled() calls
+to rcu_sched_clock_irq() and a number of the functions that it calls.
+The point of this is to help track down a situation where lockdep appears
+to be insisting that interrupts are enabled within these functions, which

+Subject: rcu: Fix stall-warning deadlock due to non-release of rcu_node ->lock
+
+From: Yanfei Xu <yanfei.xu@windriver.com>
+
+[ Upstream commit dc87740c8a6806bd2162bfb441770e4e53be5601 ]
+
+If rcu_print_task_stall() is invoked on an rcu_node structure that does
+not contain any tasks blocking the current grace period, it takes an
+early exit that fails to release that rcu_node structure's lock. This
+results in a self-deadlock, which is detected by lockdep.
+
+To reproduce this bug:
+
+tools/testing/selftests/rcutorture/bin/kvm.sh --allcpus --duration 3 --trust-make --configs "TREE03" --kconfig "CONFIG_PROVE_LOCKING=y" --bootargs "rcutorture.stall_cpu=30 rcutorture.stall_cpu_block=1 rcutorture.fwd_progress=0 rcutorture.test_boost=0"
+
+This will also result in other complaints, including RCU's scheduler
+hook complaining about blocking rather than preemption and an rcutorture
+writer stall.
+
+Only a partial RCU CPU stall warning message will be printed because of
+the self-deadlock.
+
+This commit therefore releases the lock on the rcu_print_task_stall()
+function's early exit path.

+Subject: rcu: Fix to include first blocked task in stall warning

+From: Yanfei Xu <yanfei.xu@windriver.com>
+
+[ Upstream commit e6a901a44f76878ed1653626c9ff4cfc5a3f58f8 ]
+
+The for loop in rcu_print_task_stall() always omits ts[0], which points
+to the first task blocking the stalled grace period. This in turn fails
+to count this first task, which means that ndetected will be equal to
+zero when all CPUs have passed through their quiescent states and only
+one task is blocking the stalled grace period. This zero value for
+ndetected will in turn result in an incorrect "All QSes seen" message:

+Subject: rcu/tree: Handle VM stoppage in stall detection
+
+From: Sergey Senozhatsky <senozhatsky@chromium.org>
+
+[ Upstream commit ccfc9dd6914feaa9a81f10f9cce56eb0f7712264 ]
+
+The soft watchdog timer function checks if a virtual machine
+was suspended and hence what looks like a lockup in fact
+is a false positive.
+
+This is what kvm_check_and_clear_guest_paused() does: it
+tests guest PVCLOCK_GUEST_STOPPED (which is set by the host)
+and if it's set then we need to touch all watchdogs and bail
+out.
+
+Watchdog timer function runs from IRQ, so PVCLOCK_GUEST_STOPPED
+check works fine.
+
+There is, however, one more watchdog that runs from IRQ, so
+watchdog timer fn races with it, and that watchdog is not aware
+of PVCLOCK_GUEST_STOPPED - RCU stall detector.
+
+apic_timer_interrupt()
+ smp_apic_timer_interrupt()
+ hrtimer_interrupt()
+ __hrtimer_run_queues()
+ tick_sched_timer()
+ tick_sched_handle()
+ update_process_times()
+ rcu_sched_clock_irq()
+
+This triggers RCU stalls on our devices during VM resume.
+
+If tick_sched_handle()->rcu_sched_clock_irq() runs on a VCPU
+before watchdog_timer_fn()->kvm_check_and_clear_guest_paused()
+then there is nothing on this VCPU that touches watchdogs and
+RCU reads stale gp stall timestamp and new jiffies value, which
+makes it think that RCU has stalled.
+
+Make RCU stall watchdog aware of PVCLOCK_GUEST_STOPPED and
+don't report RCU stalls when we resume the VM.

+Subject: regulator: vctrl: Avoid lockdep warning in enable/disable ops
+
+From: Chen-Yu Tsai <wenst@chromium.org>
+
+[ Upstream commit 21e39809fd7c4b8ff3662f23e0168e87594c8ca8 ]
+
+vctrl_enable() and vctrl_disable() call regulator_enable() and
+regulator_disable(), respectively. However, vctrl_* are regulator ops
+and should not be calling the locked regulator APIs. Doing so results in
+a lockdep warning.
+
+Instead of exporting more internal regulator ops, model the ctrl supply
+as an actual supply to vctrl-regulator. At probe time this driver still
+needs to use the consumer API to fetch its constraints, but otherwise
+lets the regulator core handle the upstream supply for it.
+
+The enable/disable/is_enabled ops are not removed, but now only track
+state internally. This preserves the original behavior with the ops
+being available, but one could argue that the original behavior was
+already incorrect: the internal state would not match the upstream
+supply if that supply had another consumer that enabled the supply,
+while vctrl-regulator was not enabled.
+
+The lockdep warning is as follows:
+

+Subject: regulator: vctrl: Use locked regulator_get_voltage in probe path
+
+From: Chen-Yu Tsai <wenst@chromium.org>
+
+[ Upstream commit 98e47570ba985f2310586c80409238200fa3170f ]
+
+In commit e9153311491d ("regulator: vctrl-regulator: Avoid deadlock getting
+and setting the voltage"), all calls to get/set the voltage of the
+control regulator were switched to unlocked versions to avoid deadlocks.
+However, the call in the probe path is done without regulator locks
+held. In this case the locked version should be used.
+
+Switch back to the locked regulator_get_voltage() in the probe path to
+avoid any mishaps.

+Subject: s390/ap: fix state machine hang after failure to enable irq
+
+From: Harald Freudenberger <freude@linux.ibm.com>
+
+[ Upstream commit cabebb697c98fb1f05cc950a747a9b6ec61a5b01 ]
+
+If for any reason the interrupt enable for an ap queue fails the
+state machine run for the queue returned wrong return codes to the
+caller. So the caller assumed interrupt support for this queue in
+enabled and thus did not re-establish the high resolution timer used
+for polling. In the end this let to a hang for the user space process
+waiting "forever" for the reply.
+
+This patch reworks these return codes to return correct indications
+for the caller to re-establish the timer when a queue runs without
+interrupt support.
+
+Please note that this is fixing a wrong behavior after a first
+failure (enable interrupt support for the queue) failed. However,
+looks like this occasionally happens on KVM systems.

+Subject: s390/cio: add dev_busid sysfs entry for each subchannel
+
+From: Vineeth Vijayan <vneethv@linux.ibm.com>
+
+[ Upstream commit d3683c055212bf910d4e318f7944910ce10dbee6 ]
+
+Introduce dev_busid, which exports the device-id associated with the
+io-subchannel (and message-subchannel). The dev_busid indicates that of
+the device which may be physically installed on the corrosponding
+subchannel. The dev_busid value "none" indicates that the subchannel
+is not valid, there is no I/O device currently associated with the
+subchannel.
+
+The dev_busid information would be helpful to write device-specific
+udev-rules associated with the subchannel. The dev_busid interface would
+be available even when the sch is not bound to any driver or if there is
+no operational device connected on it. Hence this attribute can be used to
+write udev-rules which are specific to the device associated with the
+subchannel.

+Currently allocation and registration of s390dbf debug areas are tied

+Subject: s390/debug: keep debug data on resize
+
+From: Peter Oberparleiter <oberpar@linux.ibm.com>
+
+[ Upstream commit 1204777867e8486a88dbb4793fe256b31ea05eeb ]
+
+Any previously recorded s390dbf debug data is reset when a debug area
+is resized using the 'pages' sysfs attribute. This can make
+live-debugging unnecessarily complex.
+
+Fix this by copying existing debug data to the newly allocated debug
+area when resizing.

+Subject: s390/pci: fix misleading rc in clp_set_pci_fn()
+
+From: Niklas Schnelle <schnelle@linux.ibm.com>
+
+[ Upstream commit f7addcdd527a6dddfebe20c358b87bdb95624612 ]
+
+Currently clp_set_pci_fn() always returns 0 as long as the CLP request
+itself succeeds even if the operation itself returns a response code
+other than CLP_RC_OK or CLP_RC_SETPCIFN_ALRDY. This is highly misleading
+because calling code assumes that a zero rc means that the operation was
+successful.
+
+Fix this by returning the response code or cc on failure with the
+exception of the special handling for CLP_RC_SETPCIFN_ALRDY. Also let's
+not assume that the returned function handle for CLP_RC_SETPCIFN_ALRDY
+is 0, we don't need it anyway.

+
+[ Upstream commit 8617bb74006252cb2286008afe7d6575a6425857 ]
+
+Tests showed a mismatch between what the CCA tool reports about
+the APKA master key state and what's displayed by the zcrypt dd
+in sysfs. After some investigation, we found out that the
+documentation which was the source for the zcrypt dd implementation
+lacks the listing of 3 fields. So this patch now moves the
+evaluation of the APKA master key state to the correct offset.

+
+The task causing this is the `cppc_fie` DL task introduced by
+commit 1eb5dde674f5 ("cpufreq: CPPC: Add support for frequency
+invariance").
+
+With CONFIG_ACPI_CPPC_CPUFREQ_FIE=y and schedutil cpufreq governor on
+slow-switching system (like on this Ampere Altra WIWYNN Mt. Jade Arm
+Server):
+
+DL task `curr=sugov:112` lets `p=cppc_fie` migrate and since the latter
+is in `non_contending` state, migrate_task_rq_dl() calls
+
+ sub_running_bw()->__sub_running_bw()->cpufreq_update_util()->
+ rq_clock()->assert_clock_updated()
+
+on p.
+
+Fix this by updating the clock for a non_contending task in
+migrate_task_rq_dl() before calling sub_running_bw().

+Subject: sched/deadline: Fix reset_on_fork reporting of DL tasks
+
+From: Quentin Perret <qperret@google.com>
+
+[ Upstream commit f95091536f78971b269ec321b057b8d630b0ad8a ]
+
+It is possible for sched_getattr() to incorrectly report the state of
+the reset_on_fork flag when called on a deadline task.
+
+Indeed, if the flag was set on a deadline task using sched_setattr()
+with flags (SCHED_FLAG_RESET_ON_FORK | SCHED_FLAG_KEEP_PARAMS), then
+p->sched_reset_on_fork will be set, but __setscheduler() will bail out
+early, which means that the dl_se->flags will not get updated by
+__setscheduler_params()->__setparam_dl(). Consequently, if
+sched_getattr() is then called on the task, __getparam_dl() will
+override kattr.sched_flags with the now out-of-date copy in dl_se->flags
+and report the stale value to userspace.
+
+To fix this, make sure to only copy the flags that are relevant to
+sched_deadline to and from the dl_se->flags field.

+Subject: sched: Fix UCLAMP_FLAG_IDLE setting
+
+From: Quentin Perret <qperret@google.com>
+
+[ Upstream commit ca4984a7dd863f3e1c0df775ae3e744bff24c303 ]
+
+The UCLAMP_FLAG_IDLE flag is set on a runqueue when dequeueing the last
+uclamp active task (that is, when buckets.tasks reaches 0 for all
+buckets) to maintain the last uclamp.max and prevent blocked util from
+suddenly becoming visible.
+
+However, there is an asymmetry in how the flag is set and cleared which
+can lead to having the flag set whilst there are active tasks on the rq.
+Specifically, the flag is cleared in the uclamp_rq_inc() path, which is
+called at enqueue time, but set in uclamp_rq_dec_id() which is called
+both when dequeueing a task _and_ in the update_uclamp_active() path. As
+a result, when both uclamp_rq_{dec,ind}_id() are called from
+update_uclamp_active(), the flag ends up being set but not cleared,
+hence leaving the runqueue in a broken state.
+
+Fix this by clearing the flag in update_uclamp_active() as well.

+Subject: soc: qcom: rpmhpd: Use corner in power_off
+
+From: Bjorn Andersson <bjorn.andersson@linaro.org>
+
+[ Upstream commit d43b3a989bc8c06fd4bbb69a7500d180db2d68e8 ]
+
+rpmhpd_aggregate_corner() takes a corner as parameter, but in
+rpmhpd_power_off() the code requests the level of the first corner
+instead.
+
+In all (known) current cases the first corner has level 0, so this
+change should be a nop, but in case that there's a power domain with a
+non-zero lowest level this makes sure that rpmhpd_power_off() actually
+requests the lowest level - which is the closest to "power off" we can
+get.
+
+While touching the code, also skip the unnecessary zero-initialization
+of "ret".

+Subject: soc: qcom: smsm: Fix missed interrupts if state changes while masked
+
+From: Stephan Gerhold <stephan@gerhold.net>
+
+[ Upstream commit e3d4571955050736bbf3eda0a9538a09d9fcfce8 ]
+
+The SMSM driver detects interrupt edges by tracking the last state
+it has seen (and has triggered the interrupt handler for). This works
+fine, but only if the interrupt does not change state while masked.
+
+For example, if an interrupt is unmasked while the state is HIGH,
+the stored last_value for that interrupt might still be LOW. Then,
+when the remote processor triggers smsm_intr() we assume that nothing
+has changed, even though the state might have changed from HIGH to LOW.
+
+Attempt to fix this by checking the current remote state before
+unmasking an IRQ. Use atomic operations to avoid the interrupt handler
+from interfering with the unmask function.
+
+This fixes modem crashes in some edge cases with the BAM-DMUX driver.
+Specifically, the BAM-DMUX interrupt handler is not called for the
+HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded
+(and therefore unmasks the interrupt) after the modem was already started:

+Subject: spi: spi-fsl-dspi: Fix issue with uninitialized dma_slave_config
+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit 209ab223ad5b18e437289235e3bde12593b94ac4 ]
+
+Depending on the DMA driver being used, the struct dma_slave_config may
+need to be initialized to zero for the unused data.
+
+For example, we have three DMA drivers using src_port_window_size and
+dst_port_window_size. If these are left uninitialized, it can cause DMA
+failures.
+
+For spi-fsl-dspi, this is probably not currently an issue but is still
+good to fix though.

+From: Quanyang Wang <quanyang.wang@windriver.com>
+
+[ Upstream commit 26cfc0dbe43aae60dc03af27077775244f26c167 ]
+
+The function wait_for_completion_interruptible_timeout will return
+-ERESTARTSYS immediately when receiving SIGKILL signal which is sent
+by "jffs2_gcd_mtd" during umounting jffs2. This will break the SPI memory
+operation because the data transmitting may begin before the command or
+address transmitting completes. Use wait_for_completion_timeout to prevent
+the process from being interruptible.

+Subject: tcp: seq_file: Avoid skipping sk during tcp_seek_last_pos
+
+From: Martin KaFai Lau <kafai@fb.com>
+
+[ Upstream commit 525e2f9fd0229eb10cb460a9e6d978257f24804e ]
+
+st->bucket stores the current bucket number.
+st->offset stores the offset within this bucket that is the sk to be
+seq_show(). Thus, st->offset only makes sense within the same
+st->bucket.
+
+These two variables are an optimization for the common no-lseek case.
+When resuming the seq_file iteration (i.e. seq_start()),
+tcp_seek_last_pos() tries to continue from the st->offset
+at bucket st->bucket.
+
+However, it is possible that the bucket pointed by st->bucket
+has changed and st->offset may end up skipping the whole st->bucket
+without finding a sk. In this case, tcp_seek_last_pos() currently
+continues to satisfy the offset condition in the next (and incorrect)
+bucket. Instead, regardless of the offset value, the first sk of the
+next bucket should be returned. Thus, "bucket == st->bucket" check is
+added to tcp_seek_last_pos().
+
+The chance of hitting this is small and the issue is a decade old,
+so targeting for the next tree.

+Subject: tpm: ibmvtpm: Avoid error message when process gets signal while
+ waiting
+
+From: Stefan Berger <stefanb@linux.ibm.com>
+
+[ Upstream commit 047d4226b0bca1cda5267dc68bc8291cce5364ac ]
+
+When rngd is run as root then lots of these types of message will appear
+in the kernel log if the TPM has been configured to provide random bytes:
+
+[ 7406.275163] tpm tpm0: tpm_transmit: tpm_recv: error -4
+
+The issue is caused by the following call that is interrupted while
+waiting for the TPM's response.
+
+sig = wait_event_interruptible(ibmvtpm->wq, !ibmvtpm->tpm_processing_cmd);
+
+Rather than waiting for the response in the low level driver, have it use
+the polling loop in tpm_try_transmit() that uses a command's duration to
+poll until a result has been returned by the TPM, thus ending when the
+timeout has occurred but not responding to signals and ctrl-c anymore. To
+stay in this polling loop extend tpm_ibmvtpm_status() to return
+'true' for as long as the vTPM is indicated as being busy in
+tpm_processing_cmd. Since the loop requires the TPM's timeouts, get them
+now using tpm_get_timeouts() after setting the TPM2 version flag on the
+chip.
+
+To recreat the resolved issue start rngd like this:
+
+sudo rngd -r /dev/hwrng -t
+sudo rngd -r /dev/tpm0 -t

+Subject: udf: Check LVID earlier
+
+From: Jan Kara <jack@suse.cz>
+
+[ Upstream commit 781d2a9a2fc7d0be53a072794dc03ef6de770f3d ]
+
+We were checking validity of LVID entries only when getting
+implementation use information from LVID in udf_sb_lvidiu(). However if
+the LVID is suitably corrupted, it can cause problems also to code such
+as udf_count_free() which doesn't use udf_sb_lvidiu(). So check validity
+of LVID already when loading it from the disk and just disable LVID
+altogether when it is not valid.

+Subject: udf: Fix iocharset=utf8 mount option
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit b645333443712d2613e4e863f81090d5dc509657 ]
+
+Currently iocharset=utf8 mount option is broken. To use UTF-8 as iocharset,
+it is required to use utf8 mount option.
+
+Fix iocharset=utf8 mount option to use be equivalent to the utf8 mount
+option.
+
+If UTF-8 as iocharset is used then s_nls_map is set to NULL. So simplify
+code around, remove UDF_FLAG_NLS_MAP and UDF_FLAG_UTF8 flags as to
+distinguish between UTF-8 and non-UTF-8 it is needed just to check if
+s_nls_map set to NULL or not.

+Subject: usb: bdc: Fix a resource leak in the error handling path of
+ 'bdc_probe()'
+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 6f15a2a09cecb7a2faba4a75bbd101f6f962294b ]
+
+If an error occurs after a successful 'clk_prepare_enable()' call, it must
+be undone by a corresponding 'clk_disable_unprepare()' call.
+This call is already present in the remove function.
+
+Add this call in the error handling path and reorder the code so that the
+'clk_prepare_enable()' call happens later in the function.
+The goal is to have as much managed resources functions as possible
+before the 'clk_prepare_enable()' call in order to keep the error handling
+path simple.
+
+While at it, remove the now unneeded 'clk' variable.

+Subject: usb: dwc3: qcom: add IRQ check
+
+From: Sergey Shtylyov <s.shtylyov@omp.ru>
+
+[ Upstream commit 175006956740f70ca23394c58f8d7804776741bd ]
+
+In dwc3_qcom_acpi_register_core(), the driver neglects to check the result
+of platform_get_irq()'s call and blithely assigns the negative error codes
+to the allocated child device's IRQ resource and then passing this resource
+to platform_device_add_resources() and later causing dwc3_otg_get_irq() to
+fail anyway. Stop calling platform_device_add_resources() with the invalid
+IRQ #s, so that there's less complexity in the IRQ error checking.

+Subject: usb: ehci-orion: Handle errors of clk_prepare_enable() in probe
+
+From: Evgeny Novikov <novikov@ispras.ru>
+
+[ Upstream commit 4720f1bf4ee4a784d9ece05420ba33c9222a3004 ]
+
+ehci_orion_drv_probe() did not account for possible errors of
+clk_prepare_enable() that in particular could cause invocation of
+clk_disable_unprepare() on clocks that were not prepared/enabled yet,
+e.g. in remove or on handling errors of usb_add_hcd() in probe. Though,
+there were several patches fixing different issues with clocks in this
+driver, they did not solve this problem.
+
+Add handling of errors of clk_prepare_enable() in ehci_orion_drv_probe()
+to avoid calls of clk_disable_unprepare() without previous successful
+invocation of clk_prepare_enable().

+
+soc_device_match() is intended as a last resort, to handle e.g. quirks
+that cannot be handled by matching based on a compatible value.
+
+As the device nodes for the Renesas USB 3.0 Peripheral Controller on
+R-Car E3 and RZ/G2E do have SoC-specific compatible values, the latter
+can and should be used to match against these devices.
+
+This also fixes support for the USB 3.0 Peripheral Controller on the
+R-Car E3e (R8A779M6) SoC, which is a different grading of the R-Car E3
+(R8A77990) SoC, using the same SoC-specific compatible value.

+Subject: usb: phy: twl6030: add IRQ checks
+
+From: Sergey Shtylyov <s.shtylyov@omp.ru>
+
+[ Upstream commit 0881e22c06e66af0b64773c91c8868ead3d01aa1 ]
+
+The driver neglects to check the result of platform_get_irq()'s calls and
+blithely passes the negative error codes to request_threaded_irq() (which
+takes *unsigned* IRQ #), causing them both to fail with -EINVAL, overriding
+an original error code. Stop calling request_threaded_irq() with the
+invalid IRQ #s.

+Subject: x86/mce: Defer processing of early errors
+
+From: Borislav Petkov <bp@alien8.de>
+
+[ Upstream commit 3bff147b187d5dfccfca1ee231b0761a89f1eff5 ]
+
+When a fatal machine check results in a system reset, Linux does not
+clear the error(s) from machine check bank(s) - hardware preserves the
+machine check banks across a warm reset.
+
+During initialization of the kernel after the reboot, Linux reads, logs,
+and clears all machine check banks.
+
+But there is a problem. In:
+
+ 5de97c9f6d85 ("x86/mce: Factor out and deprecate the /dev/mcelog driver")
+
+the call to mce_register_decode_chain() moved later in the boot
+sequence. This means that /dev/mcelog doesn't see those early error
+logs.
+
+This was partially fixed by:
+
+ cd9c57cad3fe ("x86/MCE: Dump MCE to dmesg if no consumers")
+
+which made sure that the logs were not lost completely by printing
+to the console. But parsing console logs is error prone. Users of
+/dev/mcelog should expect to find any early errors logged to standard
+places.
+
+Add a new flag MCP_QUEUE_LOG to machine_check_poll() to be used in early
+machine check initialization to indicate that any errors found should
+just be queued to genpool. When mcheck_late_init() is called it will
+call mce_schedule_work() to actually log and flush any errors queued in
+the genpool.
+
+ [ Based on an original patch, commit message by and completely
+ productized by Tony Luck. ]
+
+Fixes: 5de97c9f6d85 ("x86/mce: Factor out and deprecate the /dev/mcelog driver")
