+Subject: apparmor: ensure WB_HISTORY_SIZE value is a power of 2
+
+From: Ryan Lee <ryan.lee@canonical.com>
+
+[ Upstream commit 6c055e62560b958354625604293652753d82bcae ]
+
+WB_HISTORY_SIZE was defined to be a value not a power of 2, despite a
+comment in the declaration of struct match_workbuf stating it is and a
+modular arithmetic usage in the inc_wb_pos macro assuming that it is. Bump
+WB_HISTORY_SIZE's value up to 32 and add a BUILD_BUG_ON_NOT_POWER_OF_2
+line to ensure that any future changes to the value of WB_HISTORY_SIZE
+respect this requirement.
+
+Fixes: 136db994852a ("apparmor: increase left match history buffer size")

+Subject: apparmor: Fix unaligned memory accesses in KUnit test
+
+From: Helge Deller <deller@gmx.de>
+
+[ Upstream commit c68804199dd9d63868497a27b5da3c3cd15356db ]
+
+The testcase triggers some unnecessary unaligned memory accesses on the
+parisc architecture:
+ Kernel: unaligned access to 0x12f28e27 in policy_unpack_test_init+0x180/0x374 (iir 0x0cdc1280)
+ Kernel: unaligned access to 0x12f28e67 in policy_unpack_test_init+0x270/0x374 (iir 0x64dc00ce)
+
+Use the existing helper functions put_unaligned_le32() and
+put_unaligned_le16() to avoid such warnings on architectures which
+prefer aligned memory accesses.

+

+
+The reference manual for the i.MX8MM states the clock rate in
+MMC mode is 1/2 of the input clock, therefore to properly run
+at HS400 rates, the input clock must be 400MHz to operate at
+200MHz. Currently the clock is set to 200MHz which is half the
+rate it should be, so the throughput is half of what it should be
+for HS400 operation.

+
+[ Upstream commit ead3d7b2b6afa5ee7958620c4329982a7d9c2b78 ]
+
+flow_dissector_is_valid_access doesn't check that the context access is
+aligned. As a consequence, an unaligned access within one of the exposed
+field is considered valid and later rejected by
+flow_dissector_convert_ctx_access when we try to convert it.
+
+The later rejection is problematic because it's reported as a verifier
+bug with a kernel warning and doesn't point to the right instruction in
+verifier logs.

+Subject: bpf, ktls: Fix data corruption when using bpf_msg_pop_data() in ktls
+
+From: Jiayuan Chen <jiayuan.chen@linux.dev>
+
+[ Upstream commit 178f6a5c8cb3b6be1602de0964cd440243f493c9 ]
+
+When sending plaintext data, we initially calculated the corresponding
+ciphertext length. However, if we later reduced the plaintext data length
+via socket policy, we failed to recalculate the ciphertext length.
+
+This results in transmitting buffers containing uninitialized data during
+ciphertext transmission.
+
+This causes uninitialized bytes to be appended after a complete
+"Application Data" packet, leading to errors on the receiving end when
+parsing TLS record.

+From: Yuan Chen <chenyuan@kylinos.cn>
+
+[ Upstream commit 99fe8af069a9fa5b09140518b1364e35713a642e ]
+
+In function dump_xx_nlmsg(), when realloc() fails to allocate memory,
+the original pointer to the buffer is overwritten with NULL. This causes
+a memory leak because the previously allocated buffer becomes unreachable
+without being freed.

+Subject: caif: reduce stack size, again
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit b630c781bcf6ff87657146661816d0d30a902139 ]
+
+I tried to fix the stack usage in this function a couple of years ago,
+but there is still a problem with the latest gcc versions in some
+configurations:
+
+net/caif/cfctrl.c:553:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]
+
+Reduce this once again, with a separate cfctrl_link_setup() function that
+holds the bulk of all the local variables. It also turns out that the
+param[] array that takes up a large portion of the stack is write-only
+and can be left out here.

+Subject: clk: davinci: Add NULL check in davinci_lpsc_clk_register()
+
+From: Henry Martin <bsdhenrymartin@gmail.com>
+
+[ Upstream commit 13de464f445d42738fe18c9a28bab056ba3a290a ]
+
+devm_kasprintf() returns NULL when memory allocation fails. Currently,
+davinci_lpsc_clk_register() does not check for this case, which results
+in a NULL pointer dereference.
+
+Add NULL check after devm_kasprintf() to prevent this issue and ensuring
+no resources are left allocated.

+From: Paul Kocialkowski <paulk@sys-base.io>
+
+[ Upstream commit e8ab346f9907a1a3aa2f0e5decf849925c06ae2e ]
+
+The de clock is marked with CLK_SET_RATE_PARENT, which is really not
+necessary (as confirmed from experimentation) and significantly
+restricts flexibility for other clocks using the same parent.
+
+In addition the source selection (parent) field is marked as using
+2 bits, when it the documentation reports that it uses 3.
+
+Fix both issues in the de clock definition.

+From: Lifeng Zheng <zhenglifeng1@huawei.com>
+
+[ Upstream commit d1378d1d7edb3a4c4935a44fe834ae135be03564 ]
+
+In cpufreq_policy_put_kobj(), policy->rwsem is used. But in
+cpufreq_policy_alloc(), if freq_qos_add_notifier() returns an error, error
+path via err_kobj_remove or err_min_qos_notifier will be reached and
+cpufreq_policy_put_kobj() will be called before policy->rwsem is
+initialized. Thus, the calling of init_rwsem() should be moved to where
+before these two error paths can be reached.

+Subject: crypto: qat - fix seq_file position update in adf_ring_next()
+
+From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>
+
+[ Upstream commit 6908c5f4f066a0412c3d9a6f543a09fa7d87824b ]
+
+The `adf_ring_next()` function in the QAT debug transport interface
+fails to correctly update the position index when reaching the end of
+the ring elements. This triggers the following kernel warning when
+reading ring files, such as
+/sys/kernel/debug/qat_c6xx_<D:B:D:F>/transport/bank_00/ring_00:
+
+ [27725.022965] seq_file: buggy .next function adf_ring_next [intel_qat] did not update position index
+
+Ensure that the `*pos` index is incremented before returning NULL when
+after the last element in the ring is found, satisfying the seq_file API
+requirements and preventing the warning.

+There is a small typo in phm_wait_on_indirect_register().
+
+Swap mask and value arguments provided to phm_wait_on_register() so that
+they satisfy the function signature and actual usage scheme.
+
+Found by Linux Verification Center (linuxtesting.org) with Svace static

+
+In practice this doesn't fix any issues because the only place this
+function is used uses the same value for the value and mask.

+
+In the function drm_gem_fb_init_with_funcs, the framebuffer (fb)
+and its corresponding object ID have already been registered.
+
+So we need to cleanup the drm framebuffer if the subsequent
+execution of drm_gem_fb_afbc_init fails.
+
+Directly call drm_framebuffer_put to ensure that all fb related

+f2fs_truncate_blocks_exit: dev = (7,0), ino = 8, ret = -2
+
+The root cause is: in the fuzzed image, dnode #8 belongs to inode #7,
+after inode #7 eviction, dnode #8 was dropped.
+
+However there is dirent that has ino #8, so, once we unlink file3, in
+f2fs_evict_inode(), both f2fs_truncate() and f2fs_update_inode_page()
+will fail due to we can not load node #8, result in we missed to call
+f2fs_inode_synced() to clear inode dirty status.
+
+Let's fix this by calling f2fs_inode_synced() in error path of
+f2fs_evict_inode().
+
+PS: As I verified, the reproducer [2] can trigger this bug in v6.1.129,
+but it failed in v6.16-rc4, this is because the testcase will stop due to
+other corruption has been detected by f2fs:
+
+F2FS-fs (loop0): inconsistent node block, node_type:2, nid:8, node_footer[nid:8,ino:8,ofs:0,cpver:5013063228981249506,blkaddr:15366]
+F2FS-fs (loop0): f2fs_lookup: inode (ino=9) has zero i_nlink
+
+Fixes: 0f18b462b2e5 ("f2fs: flush inode metadata when checkpoint is doing")

+The root cause is w/ a fuzzed image, f2fs may missed to clear FI_DIRTY_INODE
+flag for target inode, after f2fs_evict_inode(), the inode is still linked in
+sbi->inode_list[DIRTY_META] global list, once it triggers checkpoint,
+f2fs_sync_inode_meta() may access the released inode.
+
+In f2fs_evict_inode(), let's always call f2fs_inode_synced() to clear
+FI_DIRTY_INODE flag and drop inode from global dirty list to avoid this
+UAF issue.

+
+From: Chenyuan Yang <chenyuan0y@gmail.com>
+
+[ Upstream commit da11e6a30e0bb8e911288bdc443b3dc8f6a7cac7 ]
+
+fb_add_videomode() can fail with -ENOMEM when its internal kmalloc() cannot
+allocate a struct fb_modelist. If that happens, the modelist stays empty but
+the driver continues to register. Add a check for its return value to prevent
+poteintial null-ptr-deref, which is similar to the commit 17186f1f90d3 ("fbdev:
+Fix do_register_framebuffer to prevent null-ptr-deref in fb_videomode_to_var").

+Subject: fs/orangefs: Allow 2 more characters in do_c_string()
+
+From: Dan Carpenter <dan.carpenter@linaro.org>
+
+[ Upstream commit 2138e89cb066b40386b1d9ddd61253347d356474 ]
+
+The do_k_string() and do_c_string() functions do essentially the same
+thing which is they add a string and a comma onto the end of an existing
+string. At the end, the caller will overwrite the last comma with a
+newline. Later, in orangefs_kernel_debug_init(), we add a newline to
+the string.
+
+The change to do_k_string() is just cosmetic. I moved the "- 1" to
+the other side of the comparison and made it "+ 1". This has no
+effect on runtime, I just wanted the functions to match each other
+and the rest of the file.
+
+However in do_c_string(), I removed the "- 2" which allows us to print
+two extra characters. I noticed this issue while reviewing the code
+and I doubt affects anything in real life. My guess is that this was
+double counting the comma and the newline. The "+ 1" accounts for
+the newline, and the caller will delete the final comma which ensures
+there is enough space for the newline.
+
+Removing the "- 2" lets us print 2 more characters, but mainly it makes
+the code more consistent and understandable for reviewers.

+
+From: RubenKelevra <rubenkelevra@gmail.com>
+

+
+The macro takes a parameter called "p" but references "fc" internally.
+This happens to compile as long as callers pass a variable named fc,
+but breaks otherwise. Rename the first parameter to “fc” to match the
+usage and to be consistent with warnfc() / errorfc().

+and add check wheather extree is locked in hfsplus_free_extents().
+
+However, when operations such as hfsplus_file_release,

+concurrently in different files, it is very likely to trigger the
+WARN_ON, which will lead syzbot and xfstest to consider it as an

+has locked the tree. This is the wrong behavior of the code and

+
+[ Upstream commit 856db37592021e9155384094e331e2d4589f28b1 ]
+
+In dbAllocCtl(), read_metapage() increases the reference count of the
+metapage. However, when dp->tree.budmin < 0, the function returns -EIO
+without calling release_metapage() to decrease the reference count,
+leading to a memory leak.
+
+Add release_metapage(mp) before the error return to properly manage
+the metapage reference count and prevent the leak.

+Subject: m68k: Don't unregister boot console needlessly
+
+From: Finn Thain <fthain@linux-m68k.org>
+
+[ Upstream commit 83f672a7f69ec38b1bbb27221e342937f68c11c7 ]
+
+When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to
+generate console output. That will continue to work even after
+debug_cons_nputs() becomes unavailable so there's no need to
+unregister the boot console.
+
+Take the opportunity to remove a repeated MACH_IS_* test. Use the
+actual .write method (instead of a wrapper) and test that pointer
+instead. This means adding an unused parameter to debug_cons_nputs() for
+consistency with the struct console API.
+
+early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late,
+head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol
+depend on the latter, to obviate some ifdef conditionals.

+Subject: module: Restore the moduleparam prefix length check
+
+From: Petr Pavlu <petr.pavlu@suse.com>
+
+[ Upstream commit bdc877ba6b7ff1b6d2ebeff11e63da4a50a54854 ]
+
+The moduleparam code allows modules to provide their own definition of
+MODULE_PARAM_PREFIX, instead of using the default KBUILD_MODNAME ".".
+
+Commit 730b69d22525 ("module: check kernel param length at compile time,
+not runtime") added a check to ensure the prefix doesn't exceed
+MODULE_NAME_LEN, as this is what param_sysfs_builtin() expects.
+
+Later, commit 58f86cc89c33 ("VERIFY_OCTAL_PERMISSIONS: stricter checking
+for sysfs perms.") removed this check, but there is no indication this was
+intentional.
+
+Since the check is still useful for param_sysfs_builtin() to function
+properly, reintroduce it in __module_param_call(), but in a modernized form
+using static_assert().
+
+While here, clean up the __module_param_call() comments. In particular,
+remove the comment "Default value instead of permissions?", which comes
+from commit 9774a1f54f17 ("[PATCH] Compile-time check re world-writeable
+module params"). This comment was related to the test variable
+__param_perm_check_##name, which was removed in the previously mentioned
+commit 58f86cc89c33.

+The expression '1 << EraseUnitSize' is evaluated in int, which causes
+a negative result when shifting by 31 - the upper bound of the valid

+extension when storing the result in 'erase->len' (uint64_t), producing

+Subject: net/sched: Restrict conditions for adding duplicating netems to qdisc
+ tree
+
+From: William Liu <will@willsroot.io>
+
+[ Upstream commit ec8e0e3d7adef940cdf9475e2352c0680189d14e ]
+
+netem_enqueue's duplication prevention logic breaks when a netem
+resides in a qdisc tree with other netems - this can lead to a
+soft lockup and OOM loop in netem_dequeue, as seen in [1].
+Ensure that a duplicating netem cannot exist in a tree with other
+netems.
+
+Previous approaches suggested in discussions in chronological order:
+
+1) Track duplication status or ttl in the sk_buff struct. Considered
+too specific a use case to extend such a struct, though this would
+be a resilient fix and address other previous and potential future
+DOS bugs like the one described in loopy fun [2].
+
+2) Restrict netem_enqueue recursion depth like in act_mirred with a
+per cpu variable. However, netem_dequeue can call enqueue on its
+child, and the depth restriction could be bypassed if the child is a
+netem.
+
+3) Use the same approach as in 2, but add metadata in netem_skb_cb
+to handle the netem_dequeue case and track a packet's involvement
+in duplication. This is an overly complex approach, and Jamal
+notes that the skb cb can be overwritten to circumvent this
+safeguard.
+
+4) Prevent the addition of a netem to a qdisc tree if its ancestral
+path contains a netem. However, filters and actions can cause a
+packet to change paths when re-enqueued to the root from netem
+duplication, leading us to the current solution: prevent a
+duplicating netem from inhabiting the same tree as other netems.

+Subject: PCI: pnv_php: Clean up allocated IRQs on unplug
+
+From: Timothy Pearson <tpearson@raptorengineering.com>
+
+[ Upstream commit 4668619092554e1b95c9a5ac2941ca47ba6d548a ]
+
+When the root of a nested PCIe bridge configuration is unplugged, the
+pnv_php driver leaked the allocated IRQ resources for the child bridges'
+hotplug event notifications, resulting in a panic.
+
+Fix this by walking all child buses and deallocating all its IRQ resources
+before calling pci_hp_remove_devices().
+
+Also modify the lifetime of the workqueue at struct pnv_php_slot::wq so
+that it is only destroyed in pnv_php_free_slot(), instead of
+pnv_php_disable_irq(). This is required since pnv_php_disable_irq() will
+now be called by workers triggered by hot unplug interrupts, so the
+workqueue needs to stay allocated.
+
+The abridged kernel panic that occurs without this patch is as follows:
+

+Subject: PCI: pnv_php: Fix surprise plug detection and recovery
+
+From: Timothy Pearson <tpearson@raptorengineering.com>
+
+[ Upstream commit a2a2a6fc2469524caa713036297c542746d148dc ]
+
+The existing PowerNV hotplug code did not handle surprise plug events
+correctly, leading to a complete failure of the hotplug system after device
+removal and a required reboot to detect new devices.
+
+This comes down to two issues:
+
+ 1) When a device is surprise removed, often the bridge upstream
+ port will cause a PE freeze on the PHB. If this freeze is not
+ cleared, the MSI interrupts from the bridge hotplug notification
+ logic will not be received by the kernel, stalling all plug events
+ on all slots associated with the PE.
+
+ 2) When a device is removed from a slot, regardless of surprise or
+ programmatic removal, the associated PHB/PE ls left frozen.
+ If this freeze is not cleared via a fundamental reset, skiboot
+ is unable to clear the freeze and cannot retrain / rescan the
+ slot. This also requires a reboot to clear the freeze and redetect
+ the device in the slot.
+
+Issue the appropriate unfreeze and rescan commands on hotplug events,
+and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.

+Subject: PCI: pnv_php: Work around switches with broken presence detection
+
+From: Timothy Pearson <tpearson@raptorengineering.com>
+
+[ Upstream commit 80f9fc2362797538ebd4fd70a1dfa838cc2c2cdb ]
+
+The Microsemi Switchtec PM8533 PFX 48xG3 [11f8:8533] PCIe switch system
+was observed to incorrectly assert the Presence Detect Set bit in its
+capabilities when tested on a Raptor Computing Systems Blackbird system,
+resulting in the hot insert path never attempting a rescan of the bus
+and any downstream devices not being re-detected.
+
+Work around this by additionally checking whether the PCIe data link is
+active or not when performing presence detection on downstream switches'
+ports, similar to the pciehp_hpc.c driver.

+Subject: pinctrl: sunxi: Fix memory leak on krealloc failure
+
+From: Yuan Chen <chenyuan@kylinos.cn>
+
+[ Upstream commit e3507c56cbb208d4f160942748c527ef6a528ba1 ]
+
+In sunxi_pctrl_dt_node_to_map(), when krealloc() fails to resize
+the pinctrl_map array, the function returns -ENOMEM directly
+without freeing the previously allocated *map buffer. This results
+in a memory leak of the original kmalloc_array allocation.

+
+When the kernel is not configured CONFIG_OF, the max14577_charger_dt_init
+function returns NULL. Fix the max14577_charger_probe functionby returning
+-ENODATA instead of potentially passing a NULL pointer to PTR_ERR.

+Subject: powerpc/eeh: Make EEH driver device hotplug safe
+
+From: Timothy Pearson <tpearson@raptorengineering.com>
+
+[ Upstream commit 1010b4c012b0d78dfb9d3132b49aa2ef024a07a7 ]
+
+Multiple race conditions existed between the PCIe hotplug driver and the
+EEH driver, leading to a variety of kernel oopses of the same general
+nature:
+
+<pcie device unplug>
+<eeh driver trigger>
+<hotplug removal trigger>
+<pcie tree reconfiguration>
+<eeh recovery next step>
+<oops in EEH driver bus iteration loop>
+
+A second class of oops is also seen when the underlying bus disappears
+during device recovery.
+
+Refactor the EEH module to be PCI rescan and remove safe. Also clean
+up a few minor formatting / readability issues.

+Subject: pps: fix poll support
+
+From: Denis OSTERLAND-HEIM <denis.osterland@diehl.com>
+
+[ Upstream commit 12c409aa1ec2592280a2ddcc66ff8f3c7f7bb171 ]
+
+Because pps_cdev_poll() returns unconditionally EPOLLIN,
+a user space program that calls select/poll get always an immediate data
+ready-to-read response. As a result the intended use to wait until next
+data becomes ready does not work.
+
+User space snippet:
+
+ struct pollfd pollfd = {
+ .fd = open("/dev/pps0", O_RDONLY),
+ .events = POLLIN|POLLERR,
+ .revents = 0 };
+ while(1) {
+ poll(&pollfd, 1, 2000/*ms*/); // returns immediate, but should wait
+ if(revents & EPOLLIN) { // always true
+ struct pps_fdata fdata;
+ memset(&fdata, 0, sizeof(memdata));
+ ioctl(PPS_FETCH, &fdata); // currently fetches data at max speed
+ }
+ }
+
+Lets remember the last fetch event counter and compare this value
+in pps_cdev_poll() with most recent event counter
+and return 0 if they are equal.

+Subject: Revert "vmci: Prevent the dispatching of uninitialized payloads"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+[ Upstream commit 8f5d9bed6122b8d96508436e5ad2498bb797eb6b ]
+
+This reverts commit bfb4cf9fb97e4063f0aa62e9e398025fb6625031.
+
+While the code "looks" correct, the compiler has no way to know that
+doing "fun" pointer math like this really isn't a write off the end of
+the structure as there is no hint anywhere that the structure has data
+at the end of it.
+
+This causes the following build warning:
+
+In function 'fortify_memset_chk',
+ inlined from 'ctx_fire_notification.isra' at drivers/misc/vmw_vmci/vmci_context.c:254:3:
+include/linux/fortify-string.h:480:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
+ 480 | __write_overflow_field(p_size_field, size);
+ | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+So revert it for now and it can come back in the future in a "sane" way
+that either correctly makes the structure know that there is trailing
+data, OR just the payload structure is properly referenced and zeroed
+out.

+From: Xiumei Mu <xmu@redhat.com>
+
+[ Upstream commit 5b32321fdaf3fd1a92ec726af18765e225b0ee2b ]
+
+The esp4_offload module, loaded during IPsec offload tests, should
+be reset to its default settings after testing.
+Otherwise, leaving it enabled could unintentionally affect subsequence
+test cases by keeping offload active.
+
+Without this fix:

+PASS: ipsec_offload
+esp4_offload 12288 0

+With this fix:

+Subject: selftests/tracing: Fix false failure of subsystem event test
+
+From: Steven Rostedt <rostedt@goodmis.org>
+
+[ Upstream commit 213879061a9c60200ba971330dbefec6df3b4a30 ]
+
+The subsystem event test enables all "sched" events and makes sure there's
+at least 3 different events in the output. It used to cat the entire trace
+file to | wc -l, but on slow machines, that could last a very long time.
+To solve that, it was changed to just read the first 100 lines of the
+trace file. This can cause false failures as some events repeat so often,
+that the 100 lines that are examined could possibly be of only one event.
+
+Instead, create an awk script that looks for 3 different events and will
+exit out after it finds them. This will find the 3 events the test looks
+for (eventually if it works), and still exit out after the test is
+satisfied and not cause slower machines to run forever.

+Subject: sh: Do not use hyphen in exported variable name
+
+From: Ben Hutchings <benh@debian.org>
+
+[ Upstream commit c32969d0362a790fbc6117e0b6a737a7e510b843 ]
+
+arch/sh/Makefile defines and exports ld-bfd to be used by
+arch/sh/boot/compressed/Makefile and arch/sh/boot/romimage/Makefile.
+However some shells, including dash, will not pass through environment
+variables whose name includes a hyphen. Usually GNU make does not use
+a shell to recurse, but if e.g. $(srctree) contains '~' it will use a
+shell here.
+
+Other instances of this problem were previously fixed by commits
+2bfbe7881ee0 "kbuild: Do not use hyphen in exported variable name"
+and 82977af93a0d "sh: rename suffix-y to suffix_y".
+
+Rename the variable to ld_bfd.

+Subject: vhost-scsi: Fix log flooding with target does not exist errors
+
+From: Mike Christie <michael.christie@oracle.com>
+
+[ Upstream commit 69cd720a8a5e9ef0f05ce5dd8c9ea6e018245c82 ]
+
+As part of the normal initiator side scanning the guest's scsi layer
+will loop over all possible targets and send an inquiry. Since the
+max number of targets for virtio-scsi is 256, this can result in 255
+error messages about targets not existing if you only have a single
+target. When there's more than 1 vhost-scsi device each with a single
+target, then you get N * 255 log messages.
+
+It looks like the log message was added by accident in:
+
+commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code from
+control queue handler")
+
+when we added common helpers. Then in:
+
+commit 09d7583294aa ("vhost/scsi: Use common handling code in request
+queue handler")
+
+we converted the scsi command processing path to use the new
+helpers so we started to see the extra log messages during scanning.
+
+The patches were just making some code common but added the vq_err
+call and I'm guessing the patch author forgot to enable the vq_err
+call (vq_err is implemented by pr_debug which defaults to off). So
+this patch removes the call since it's expected to hit this path
+during device discovery.

+Subject: vmci: Prevent the dispatching of uninitialized payloads
+
+From: Lizhi Xu <lizhi.xu@windriver.com>
+
+[ Upstream commit bfb4cf9fb97e4063f0aa62e9e398025fb6625031 ]
+
+The reproducer executes the host's unlocked_ioctl call in two different
+tasks. When init_context fails, the struct vmci_event_ctx is not fully
+initialized when executing vmci_datagram_dispatch() to send events to all
+vm contexts. This affects the datagram taken from the datagram queue of
+its context by another task, because the datagram payload is not initialized
+according to the size payload_size, which causes the kernel data to leak
+to the user space.
+
+Before dispatching the datagram, and before setting the payload content,
+explicitly set the payload content to 0 to avoid data leakage caused by
+incomplete payload initialization.

+
+From: Dan Carpenter <dan.carpenter@linaro.org>
+
+[ Upstream commit 8b61d8ca751bc15875b50e0ff6ac3ba0cf95a529 ]
+
+The "rec->len" value comes from the firmware. We generally do
+trust firmware, but it's always better to double check. If
+the length value is too large it would lead to memory corruption
+when we set "data[i] = ret;"

+Subject: wifi: ath11k: clear initialized flag for deinit-ed srng lists
+
+From: Sergey Senozhatsky <senozhatsky@chromium.org>
+
+[ Upstream commit a5b46aa7cf5f05c213316a018e49a8e086efd98e ]
+
+In a number of cases we see kernel panics on resume due
+to ath11k kernel page fault, which happens under the
+following circumstances:
+
+1) First ath11k_hal_dump_srng_stats() call
+
+ Last interrupt received for each group:
+ ath11k_pci 0000:01:00.0: group_id 0 22511ms before
+ ath11k_pci 0000:01:00.0: group_id 1 14440788ms before
+ [..]
+ ath11k_pci 0000:01:00.0: failed to receive control response completion, polling..
+ ath11k_pci 0000:01:00.0: Service connect timeout
+ ath11k_pci 0000:01:00.0: failed to connect to HTT: -110
+ ath11k_pci 0000:01:00.0: failed to start core: -110

+ ath11k_pci 0000:01:00.0: failed to reconfigure driver on crash recovery
+ [..]
+
+2) At this point reconfiguration fails (we have 2 resets) and
+ ath11k_core_reconfigure_on_crash() calls ath11k_hal_srng_deinit()
+ which destroys srng lists. However, it does not reset per-list
+ ->initialized flag.
+
+3) Second ath11k_hal_dump_srng_stats() call sees stale ->initialized
+ flag and attempts to dump srng stats:
+
+ Last interrupt received for each group:
+ ath11k_pci 0000:01:00.0: group_id 0 66785ms before

+Subject: wifi: brcmfmac: fix P2P discovery failure in P2P peer due to missing
+ P2P IE
+
+From: Gokul Sivakumar <gokulkumar.sivakumar@infineon.com>
+
+[ Upstream commit 579bf8037b70b644a674c126a32bbb2212cf5c21 ]
+
+After commit bd99a3013bdc ("brcmfmac: move configuration of probe request
+IEs"), the probe request MGMT IE addition operation brcmf_vif_set_mgmt_ie()
+got moved from the brcmf_p2p_scan_prep() to the brcmf_cfg80211_scan().
+
+Because of this, as part of the scan request handler for the P2P Discovery,
+vif struct used for adding the Probe Request P2P IE in firmware got changed
+from the P2PAPI_BSSCFG_DEVICE vif to P2PAPI_BSSCFG_PRIMARY vif incorrectly.
+So the firmware stopped adding P2P IE to the outgoing P2P Discovery probe
+requests frames and the other P2P peers were unable to discover this device
+causing a regression on the P2P feature.
+
+To fix this, while setting the P2P IE in firmware, properly use the vif of
+the P2P discovery wdev on which the driver received the P2P scan request.
+This is done by not changing the vif pointer, until brcmf_vif_set_mgmt_ie()
+is completed.

+Subject: xen/gntdev: remove struct gntdev_copy_batch from stack
+
+From: Juergen Gross <jgross@suse.com>
+
+[ Upstream commit 70045cf6593cbf0740956ea9b7b4269142c6ee38 ]
+
+When compiling the kernel with LLVM, the following warning was issued:
+
+ drivers/xen/gntdev.c:991: warning: stack frame size (1160) exceeds
+ limit (1024) in function 'gntdev_ioctl'
+
+The main reason is struct gntdev_copy_batch which is located on the
+stack and has a size of nearly 1kb.
+
+For performance reasons it shouldn't by just dynamically allocated
+instead, so allocate a new instance when needed and instead of freeing
+it put it into a list of free structs anchored in struct gntdev_priv.
+
+Fixes: a4cdb556cae0 ("xen/gntdev: add ioctl for grant copy")
