+Subject: clk: qcom: gcc-qcs404: fix initial rate of GPLL3
+
+From: Gabor Juhos <j4g8y7@gmail.com>
+
+commit 36d202241d234fa4ac50743510d098ad52bd193a upstream.
+
+The comment before the config of the GPLL3 PLL says that the
+PLL should run at 930 MHz. In contrary to this, calculating
+the frequency from the current configuration values by using
+19.2 MHz as input frequency defined in 'qcs404.dtsi', it gives
+921.6 MHz:
+
+ $ xo=19200000; l=48; alpha=0x0; alpha_hi=0x0
+ $ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l
+ 921600000.00000000000000000000
+
+Set 'alpha_hi' in the configuration to a value used in downstream
+kernels [1][2] in order to get the correct output rate:
+
+ $ xo=19200000; l=48; alpha=0x0; alpha_hi=0x70
+ $ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l
+ 930000000.00000000000000000000
+
+The change is based on static code analysis, compile tested only.

+commit 06d39d79cbd5a91a33707951ebf2512d0e759847 upstream.
+
+cmdline_ptr is an out parameter, which is not allocated by the function
+itself, and likely points into the caller's stack.
+
+cmdline refers to the pool allocation that should be freed when cleaning
+up after a failure, so pass this instead to free_pool().

+From: guoweikang <guoweikang.kernel@gmail.com>
+
+commit 45af52e7d3b8560f21d139b3759735eead8b1653 upstream.
+
+When executing the following command:
+
+ # echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter
+
+The current mod command causes a null pointer dereference. While commit
+0f17976568b3f ("ftrace: Fix regression with module command in stack_trace_filter")
+has addressed part of the issue, it left a corner case unhandled, which still
+results in a kernel crash.

+Subject: iommu/arm-smmu: Defer probe of clients after smmu device bound
+
+From: Pratyush Brahma <quic_pbrahma@quicinc.com>
+
+commit 229e6ee43d2a160a1592b83aad620d6027084aad upstream.
+
+Null pointer dereference occurs due to a race between smmu
+driver probe and client driver probe, when of_dma_configure()
+for client is called after the iommu_device_register() for smmu driver
+probe has executed but before the driver_bound() for smmu driver
+has been called.
+
+Following is how the race occurs:
+
+T1:Smmu device probe T2: Client device probe
+
+really_probe()
+arm_smmu_device_probe()
+iommu_device_register()
+ really_probe()
+ platform_dma_configure()
+ of_dma_configure()
+ of_dma_configure_id()
+ of_iommu_configure()
+ iommu_probe_device()
+ iommu_init_device()
+ arm_smmu_probe_device()
+ arm_smmu_get_by_fwnode()
+ driver_find_device_by_fwnode()
+ driver_find_device()
+ next_device()
+ klist_next()
+ /* null ptr
+ assigned to smmu */
+ /* null ptr dereference
+ while smmu->streamid_mask */
+driver_bound()
+ klist_add_tail()
+
+When this null smmu pointer is dereferenced later in
+arm_smmu_probe_device, the device crashes.
+
+Fix this by deferring the probe of the client device
+until the smmu device has bound to the arm smmu driver.

+Subject: iommu/io-pgtable-arm: Fix stage-2 map/unmap for concatenated tables
+
+From: Mostafa Saleh <smostafa@google.com>
+
+commit d71fa842d33c48ac2809ae11d2379b5a788792cb upstream.
+
+ARM_LPAE_LVL_IDX() takes into account concatenated PGDs and can return
+an index spanning multiple page-table pages given a sufficiently large
+input address. However, when the resulting index is used to calculate
+the number of remaining entries in the page, the possibility of
+concatenation is ignored and we end up computing a negative upper bound:
+
+ max_entries = ARM_LPAE_PTES_PER_TABLE(data) - map_idx_start;
+
+On the map path, this results in a negative 'mapped' value being
+returned but on the unmap path we can leak child tables if they are
+skipped in __arm_lpae_free_pgtable().
+
+Introduce an arm_lpae_max_entries() helper to convert a table index into
+the remaining number of entries within a single page-table page.

+
+commit 39e21403c978862846fa68b7f6d06f9cca235194 upstream.
+
+In kunit_debugfs_create_suite(), if alloc_string_stream() fails in the
+kunit_suite_for_each_test_case() loop, the "suite->log = stream"
+has assigned before, and the error path only free the suite->log's stream
+memory but not set it to NULL, so the later string_stream_clear() of
+suite->log in kunit_init_suite() will cause below UAF bug.
+
+Set stream pointer to NULL after free to fix it.

+Subject: leds: lp55xx: Remove redundant test for invalid channel number
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Michal Vokáč <michal.vokac@ysoft.com>
+
+commit 09b1ef9813a0742674f7efe26104403ca94a1b4a upstream.
+
+Since commit 92a81562e695 ("leds: lp55xx: Add multicolor framework
+support to lp55xx") there are two subsequent tests if the chan_nr
+(reg property) is in valid range. One in the lp55xx_init_led()
+function and one in the lp55xx_parse_common_child() function that
+was added with the mentioned commit.
+
+There are two issues with that.
+
+First is in the lp55xx_parse_common_child() function where the reg
+property is tested right after it is read from the device tree.
+Test for the upper range is not correct though. Valid reg values are
+0 to (max_channel - 1) so it should be >=.
+
+Second issue is that in case the parsed value is out of the range
+the probe just fails and no error message is shown as the code never
+reaches the second test that prints and error message.
+
+Remove the test form lp55xx_parse_common_child() function completely
+and keep the one in lp55xx_init_led() function to deal with it.

+Subject: maple_tree: refine mas_store_root() on storing NULL
+
+From: Wei Yang <richard.weiyang@gmail.com>
+
+commit 0ea120b278ad7f7cfeeb606e150ad04b192df60b upstream.
+
+Currently, when storing NULL on mas_store_root(), the behavior could be
+improved.
+
+Storing NULLs over the entire tree may result in a node being used to
+store a single range. Further stores of NULL may cause the node and
+tree to be corrupt and cause incorrect behaviour. Fixing the store to
+the root null fixes the issue by ensuring that a range of 0 - ULONG_MAX
+results in an empty tree.
+
+Users of the tree may experience incorrect values returned if the tree
+was expanded to store values, then overwritten by all NULLS, then
+continued to store NULLs over the empty area.
+
+For example possible cases are:
+
+ * store NULL at any range result a new node
+ * store NULL at range [m, n] where m > 0 to a single entry tree result
+ a new node with range [m, n] set to NULL
+ * store NULL at range [m, n] where m > 0 to an empty tree result
+ consecutive NULL slot
+ * it allows for multiple NULL entries by expanding root
+ to store NULLs to an empty tree
+
+This patch tries to improve in:
+
+ * memory efficient by setting to empty tree instead of using a node
+ * remove the possibility of consecutive NULL slot which will prohibit
+ extended null in later operation

+
+commit 316e74500d1c6589cba28cebe2864a0bceeb2396 upstream.
+
+It is not valid to call pm_runtime_set_suspended() for devices
+with runtime PM enabled because it returns -EAGAIN if it is enabled
+already and working. So, call pm_runtime_disable() before to fix it.

+From: Jinjie Ruan <ruanjinjie@huawei.com>
+
+commit d2842dec577900031826dc44e9bf0c66416d7173 upstream.
+
+In set_frame_rate(), select a rate in rate_0 or rate_1 by checking
+sd->frame_rate >= r->fps in a loop, but the loop condition terminates when
+the index reaches zero, which fails to check the last elememt in rate_0 or
+rate_1.
+
+Check for >= 0 so that the last one in rate_0 or rate_1 is also checked.

+
+If an error occurs in the probe() function, we should remove the polling

+Subject: media: ov08x40: Fix burst write sequence
+
+From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
+
+commit d0fef6de4f1b957e35a05a5ba4aab2a2576d6686 upstream.
+
+It is necessary to account for I2C quirks in the burst mode path of this
+driver. Not all I2C controllers can accept arbitrarily long writes and this
+is represented in the quirks field of the adapter structure.
+
+Prior to this patch the following error message is seen on a Qualcomm
+X1E80100 CRD.
+
+[ 38.773524] i2c i2c-2: adapter quirk: msg too long (addr 0x0036, size 290, write)
+[ 38.781454] ov08x40 2-0036: Failed regs transferred: -95
+[ 38.787076] ov08x40 2-0036: ov08x40_start_streaming failed to set regs
+
+Fix the error by breaking up the write sequence into the advertised maximum
+write size of the quirks field if the quirks field is populated.

+
+commit 8964eb23408243ae0016d1f8473c76f64ff25d20 upstream.
+
+In fimc_md_is_isp_available(), of_get_child_by_name() is called to check
+if FIMC-IS is available. Current code does not decrement the refcount of
+the returned device node, which causes an OF node reference leak. Fix it
+by calling of_node_put() at the end of the variable scope.

+Subject: media: uvcvideo: Require entities to have a non-zero unique ID
+
+From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
+
+commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195 upstream.
+
+Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero
+unique ID.
+
+```
+Each Unit and Terminal within the video function is assigned a unique
+identification number, the Unit ID (UID) or Terminal ID (TID), contained in
+the bUnitID or bTerminalID field of the descriptor. The value 0x00 is
+reserved for undefined ID,
+```
+
+So, deny allocating an entity with ID 0 or an ID that belongs to a unit
+that is already added to the list of entities.
+
+This also prevents some syzkaller reproducers from triggering warnings due
+to a chain of entities referring to themselves. In one particular case, an
+Output Unit is connected to an Input Unit, both with the same ID of 1. But
+when looking up for the source ID of the Output Unit, that same entity is
+found instead of the input entity, which leads to such warnings.
+
+In another case, a backward chain was considered finished as the source ID
+was 0. Later on, that entity was found, but its pads were not valid.
+
+Here is a sample stack trace for one of those cases.

+Subject: media: uvcvideo: Stop stream during unregister
+
+From: Ricardo Ribalda <ribalda@chromium.org>
+
+commit c9ec6f1736363b2b2bb4e266997389740f628441 upstream.
+
+uvc_unregister_video() can be called asynchronously from
+uvc_disconnect(). If the device is still streaming when that happens, a
+plethora of race conditions can occur.
+
+Make sure that the device has stopped streaming before exiting this
+function.
+
+If the user still holds handles to the driver's file descriptors, any
+ioctl will return -ENODEV from the v4l2 core.
+
+This change makes uvc more consistent with the rest of the v4l2 drivers
+using the vb2_fop_* and vb2_ioctl_* helpers.
+
+This driver (and many other usb drivers) always had this problem, but it
+wasn't possible to easily fix this until the vb2_video_unregister_device()
+helper was added. So the Fixes tag points to the creation of that helper.

+From: Jinjie Ruan <ruanjinjie@huawei.com>
+
+commit 2a20869f7d798aa2b69e45b863eaf1b1ecf98278 upstream.
+
+It is not valid to call pm_runtime_set_suspended() for devices
+with runtime PM enabled because it returns -EAGAIN if it is enabled
+already and working. So, call pm_runtime_disable() before to fix it.

+Subject: mm/damon/vaddr: fix issue in damon_va_evenly_split_region()
+
+From: Zheng Yejian <zhengyejian@huaweicloud.com>
+
+commit f3c7a1ede435e2e45177d7a490a85fb0a0ec96d1 upstream.
+
+Patch series "mm/damon/vaddr: Fix issue in
+damon_va_evenly_split_region()". v2.
+
+According to the logic of damon_va_evenly_split_region(), currently
+following split case would not meet the expectation:
+
+ Suppose DAMON_MIN_REGION=0x1000,
+ Case: Split [0x0, 0x3000) into 2 pieces, then the result would be
+ acutually 3 regions:
+ [0x0, 0x1000), [0x1000, 0x2000), [0x2000, 0x3000)
+ but NOT the expected 2 regions:
+ [0x0, 0x1000), [0x1000, 0x3000) !!!
+
+The root cause is that when calculating size of each split piece in
+damon_va_evenly_split_region():
+
+ `sz_piece = ALIGN_DOWN(sz_orig / nr_pieces, DAMON_MIN_REGION);`
+
+both the dividing and the ALIGN_DOWN may cause loss of precision, then
+each time split one piece of size 'sz_piece' from origin 'start' to 'end'
+would cause more pieces are split out than expected!!!
+
+To fix it, count for each piece split and make sure no more than
+'nr_pieces'. In addition, add above case into damon_test_split_evenly().
+
+And add 'nr_piece == 1' check in damon_va_evenly_split_region() for better
+code readability and add a corresponding kunit testcase.
+
+
+This patch (of 2):
+
+According to the logic of damon_va_evenly_split_region(), currently
+following split case would not meet the expectation:
+
+ Suppose DAMON_MIN_REGION=0x1000,

+
+The root cause is that when calculating size of each split piece in

+commit 378e8feea9a70d37a5dc1678b7ec27df21099fa5 upstream.
+
+The DP83869 PHY transceiver supports converting from RGMII to 1000base-x.
+In this operation mode, autonegotiation can be performed, as described in
+IEEE802.3.
+
+The DP83869 has a set of fiber-specific registers located at offset 0xc00.
+When the transceiver is configured in RGMII-to-1000base-x mode, these
+registers are mapped onto offset 0, which should make reading the
+autonegotiation status transparent.
+
+However, the fiber registers at offset 0xc04 and 0xc05 follow the bit
+layout specified in Clause 37, and genphy_read_status() assumes a Clause 22
+layout. Thus, genphy_read_status() doesn't properly read the capabilities
+advertised by the link partner, resulting in incorrect link parameters.
+
+Similarly, genphy_config_aneg() doesn't properly write advertised
+capabilities.
+
+Fix the 1000base-x autonegotiation procedure by replacing
+genphy_read_status() and genphy_config_aneg() with their Clause 37
+equivalents.
+
+Fixes: a29de52ba2a1 ("net: dp83869: Add ability to advertise Fiber connection")

+
+From: Vasiliy Kovalev <kovalev@altlinux.org>
+
+commit c8b359dddb418c60df1a69beea01d1b3322bfe83 upstream.
+
+Add a check to the ovl_dentry_weird() function to prevent the
+processing of directory inodes that lack the lookup function.
+This is important because such inodes can cause errors in overlayfs
+when passed to the lowerstack.

+Subject: powerpc/vdso: Drop -mstack-protector-guard flags in 32-bit files with clang
+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit d677ce521334d8f1f327cafc8b1b7854b0833158 upstream.
+
+Under certain conditions, the 64-bit '-mstack-protector-guard' flags may
+end up in the 32-bit vDSO flags, resulting in build failures due to the
+structure of clang's argument parsing of the stack protector options,
+which validates the arguments of the stack protector guard flags
+unconditionally in the frontend, choking on the 64-bit values when
+targeting 32-bit:
+
+ clang: error: invalid value 'r13' in 'mstack-protector-guard-reg=', expected one of: r2
+ clang: error: invalid value 'r13' in 'mstack-protector-guard-reg=', expected one of: r2
+ make[3]: *** [arch/powerpc/kernel/vdso/Makefile:85: arch/powerpc/kernel/vdso/vgettimeofday-32.o] Error 1
+ make[3]: *** [arch/powerpc/kernel/vdso/Makefile:87: arch/powerpc/kernel/vdso/vgetrandom-32.o] Error 1
+
+Remove these flags by adding them to the CC32FLAGSREMOVE variable, which
+already handles situations similar to this. Additionally, reformat and
+align a comment better for the expanding CONFIG_CC_IS_CLANG block.

+Subject: vmstat: call fold_vm_zone_numa_events() before show per zone NUMA event
+
+From: MengEn Sun <mengensun@tencent.com>
+
+commit 2ea80b039b9af0b71c00378523b71c254fb99c23 upstream.
+
+Since 5.14-rc1, NUMA events will only be folded from per-CPU statistics to
+per zone and global statistics when the user actually needs it.
+
+Currently, the kernel has performs the fold operation when reading
+/proc/vmstat, but does not perform the fold operation in /proc/zoneinfo.
+This can lead to inaccuracies in the following statistics in zoneinfo:
+- numa_hit
+- numa_miss
+- numa_foreign
+- numa_interleave
+- numa_local
+- numa_other
+
+Therefore, before printing per-zone vm_numa_event when reading
+/proc/zoneinfo, we should also perform the fold operation.

+Subject: zram: clear IDLE flag after recompression
+
+From: Sergey Senozhatsky <senozhatsky@chromium.org>
+
+commit f85219096648b251a81e9fe24a1974590cfc417d upstream.
+
+Patch series "zram: IDLE flag handling fixes", v2.
+
+zram can wrongly preserve ZRAM_IDLE flag on its entries which can result
+in premature post-processing (writeback and recompression) of such
+entries.
+
+This patch (of 2)
+
+Recompression should clear ZRAM_IDLE flag on the entries it has accessed,
+because otherwise some entries, specifically those for which recompression
+has failed, become immediate candidate entries for another post-processing
+(e.g. writeback).
+
+Consider the following case:
+- recompression marks entries IDLE every 4 hours and attempts
+ to recompress them
+- some entries are incompressible, so we keep them intact and
+ hence preserve IDLE flag
+- writeback marks entries IDLE every 8 hours and writebacks
+ IDLE entries, however we have IDLE entries left from
+ recompression, so writeback prematurely writebacks those
+ entries.
+
+The bug was reported by Shin Kawamura.
