+Subject: 9p/net: fix improper handling of bogus negative read/write replies
+
+From: Dominique Martinet <asmadeus@codewreck.org>
+
+[ Upstream commit d0259a856afca31d699b706ed5e2adf11086c73b ]
+
+In p9_client_write() and p9_client_read_once(), if the server
+incorrectly replies with success but a negative write/read count then we
+would consider written (negative) <= rsize (positive) because both
+variables were signed.
+
+Make variables unsigned to avoid this problem.
+
+The reproducer linked below now fails with the following error instead
+of a null pointer deref:
+9pnet: bogus RWRITE count (4294967295 > 3)

+Subject: 9p/trans_fd: mark concurrent read and writes to p9_conn->err
+
+From: Ignacio Encinas <ignacio@iencinas.com>
+
+[ Upstream commit fbc0283fbeae27b88448c90305e738991457fee2 ]
+
+Writes for the error value of a connection are spinlock-protected inside
+p9_conn_cancel, but lockless reads are present elsewhere to avoid
+performing unnecessary work after an error has been met.
+
+Mark the write and lockless reads to make KCSAN happy. Mark the write as
+exclusive following the recommendation in "Lock-Protected Writes with
+Lockless Reads" in tools/memory-model/Documentation/access-marking.txt
+while we are at it.
+
+Mark p9_fd_request and p9_conn_cancel m->err reads despite the fact that
+they do not race with concurrent writes for stylistic reasons.

+Subject: ACPI: EC: Set ec_no_wakeup for Lenovo Go S
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+[ Upstream commit b988685388effd648150aab272533f833a2a70f0 ]
+
+When AC adapter is unplugged or plugged in EC wakes from HW sleep but
+APU doesn't enter back into HW sleep.
+
+The reason this happens is that, when the APU exits HW sleep, the power
+rails controlled by the EC will power up the TCON. The TCON has a GPIO
+that will be toggled at this time. The GPIO is not marked as a wakeup
+source, but the GPIO controller still has an unserviced interrupt.
+Unserviced interrupts will block entering HW sleep again. Clearing the
+GPIO doesn't help as the TCON continues to assert it until it's been
+initialized by i2c-hid.
+
+Fixing this would require TCON F/W changes and it's already broken in
+the wild on production hardware.
+
+To avoid triggering this issue add a quirk to avoid letting EC wake
+up system at all. The power button still works properly on this system.

+Subject: bpf: Fix kmemleak warning for percpu hashmap
+
+From: Yonghong Song <yonghong.song@linux.dev>
+
+[ Upstream commit 11ba7ce076e5903e7bdc1fd1498979c331b3c286 ]
+
+Vlad Poenaru reported the following kmemleak issue:
+
+ unreferenced object 0x606fd7c44ac8 (size 32):
+ backtrace (crc 0):
+ pcpu_alloc_noprof+0x730/0xeb0
+ bpf_map_alloc_percpu+0x69/0xc0
+ prealloc_init+0x9d/0x1b0
+ htab_map_alloc+0x363/0x510
+ map_create+0x215/0x3a0
+ __sys_bpf+0x16b/0x3e0
+ __x64_sys_bpf+0x18/0x20
+ do_syscall_64+0x7b/0x150
+ entry_SYSCALL_64_after_hwframe+0x4b/0x53
+
+Further investigation shows the reason is due to not 8-byte aligned
+store of percpu pointer in htab_elem_set_ptr():
+ *(void __percpu **)(l->key + key_size) = pptr;
+
+Note that the whole htab_elem alignment is 8 (for x86_64). If the key_size
+is 4, that means pptr is stored in a location which is 4 byte aligned but
+not 8 byte aligned. In mm/kmemleak.c, scan_block() scans the memory based
+on 8 byte stride, so it won't detect above pptr, hence reporting the memory
+leak.
+
+In htab_map_alloc(), we already have
+
+ htab->elem_size = sizeof(struct htab_elem) +
+ round_up(htab->map.key_size, 8);
+ if (percpu)
+ htab->elem_size += sizeof(void *);
+ else
+ htab->elem_size += round_up(htab->map.value_size, 8);
+
+So storing pptr with 8-byte alignment won't cause any problem and can fix
+kmemleak too.
+
+The issue can be reproduced with bpf selftest as well:
+ 1. Enable CONFIG_DEBUG_KMEMLEAK config
+ 2. Add a getchar() before skel destroy in test_hash_map() in prog_tests/for_each.c.
+ The purpose is to keep map available so kmemleak can be detected.
+ 3. run './test_progs -t for_each/hash_map &' and a kmemleak should be reported.

+Subject: bpf: Only fails the busy counter check in bpf_cgrp_storage_get if it
+ creates storage
+
+From: Martin KaFai Lau <martin.lau@kernel.org>
+
+[ Upstream commit f4edc66e48a694b3e6d164cc71f059de542dfaec ]
+
+The current cgrp storage has a percpu counter, bpf_cgrp_storage_busy,
+to detect potential deadlock at a spin_lock that the local storage
+acquires during new storage creation.
+
+There are false positives. It turns out to be too noisy in
+production. For example, a bpf prog may be doing a
+bpf_cgrp_storage_get on map_a. An IRQ comes in and triggers
+another bpf_cgrp_storage_get on a different map_b. It will then
+trigger the false positive deadlock check in the percpu counter.
+On top of that, both are doing lookup only and no need to create
+new storage, so practically it does not need to acquire
+the spin_lock.
+
+The bpf_task_storage_get already has a strategy to minimize this
+false positive by only failing if the bpf_task_storage_get needs
+to create a new storage and the percpu counter is busy. Creating
+a new storage is the only time it must acquire the spin_lock.
+
+This patch borrows the same idea. Unlike task storage that
+has a separate variant for tracing (_recur) and non-tracing, this
+patch stays with one bpf_cgrp_storage_get helper to keep it simple
+for now in light of the upcoming res_spin_lock.
+
+The variable could potentially use a better name noTbusy instead
+of nobusy. This patch follows the same naming in
+bpf_task_storage_get for now.
+
+I have tested it by temporarily adding noinline to
+the cgroup_storage_lookup(), traced it by fentry, and the fentry
+program succeeded in calling bpf_cgrp_storage_get().

+Subject: bpf: Reject attaching fexit/fmod_ret to __noreturn functions
+
+From: Yafang Shao <laoar.shao@gmail.com>
+
+[ Upstream commit cfe816d469dce9c0864062cf65dd7b3c42adc6f8 ]
+
+If we attach fexit/fmod_ret to __noreturn functions, it will cause an
+issue that the bpf trampoline image will be left over even if the bpf
+link has been destroyed. Take attaching do_exit() with fexit for example.
+The fexit works as follows,
+
+ bpf_trampoline
+ + __bpf_tramp_enter
+ + percpu_ref_get(&tr->pcref);
+
+ + call do_exit()
+
+ + __bpf_tramp_exit
+ + percpu_ref_put(&tr->pcref);
+
+Since do_exit() never returns, the refcnt of the trampoline image is
+never decremented, preventing it from being freed. That can be verified
+with as follows,
+
+ $ bpftool link show <<<< nothing output
+ $ grep "bpf_trampoline_[0-9]" /proc/kallsyms
+ ffffffffc04cb000 t bpf_trampoline_6442526459 [bpf] <<<< leftover
+
+In this patch, all functions annotated with __noreturn are rejected, except
+for the following cases:
+- Functions that result in a system reboot, such as panic,
+ machine_real_restart and rust_begin_unwind
+- Functions that are never executed by tasks, such as rest_init and
+ cpu_startup_entry
+- Functions implemented in assembly, such as rewind_stack_and_make_dead and
+ xen_cpu_bringup_again, lack an associated BTF ID.
+
+With this change, attaching fexit probes to functions like do_exit() will
+be rejected.
+
+$ ./fexit
+libbpf: prog 'fexit': BPF program load failed: -EINVAL
+libbpf: prog 'fexit': -- BEGIN PROG LOAD LOG --
+Attaching fexit/fmod_ret to __noreturn functions is rejected.

+Subject: cgroup/cpuset: Don't allow creation of local partition over a remote
+ one
+
+From: Waiman Long <longman@redhat.com>
+
+[ Upstream commit 6da580ec656a5ed135db2cdf574b47635611a4d7 ]
+
+Currently, we don't allow the creation of a remote partition underneath
+another local or remote partition. However, it is currently possible to
+create a new local partition with an existing remote partition underneath
+it if top_cpuset is the parent. However, the current cpuset code does
+not set the effective exclusive CPUs correctly to account for those
+that are taken by the remote partition.
+
+Changing the code to properly account for those remote partition CPUs
+under all possible circumstances can be complex. It is much easier to
+not allow such a configuration which is not that useful. So forbid
+that by making sure that exclusive_cpus mask doesn't overlap with
+subpartitions_cpus and invalidate the partition if that happens.

+
+When reparse point in SMB1 query_path_info() callback was detected then
+query also for EA $LXDEV. In this EA are stored device major and minor
+numbers used by WSL CHR and BLK reparse points. Without major and minor
+numbers, stat() syscall does not work for char and block devices.
+
+Similar code is already in SMB2+ query_path_info() callback function.

+Subject: clk: check for disabled clock-provider in
+ of_clk_get_hw_from_clkspec()
+
+From: Heiko Stuebner <heiko@sntech.de>
+
+[ Upstream commit b20150d499b3ee5c2d632fbc5ac94f98dd33accf ]
+
+of_clk_get_hw_from_clkspec() checks all available clock-providers by
+comparing their of nodes to the one from the clkspec. If no matching
+clock provider is found, the function returns -EPROBE_DEFER to cause a
+re-check at a later date. If a matching clock provider is found, an
+authoritative answer can be retrieved from it whether the clock exists
+or not.
+
+This does not take into account that the clock-provider may never
+appear, because it's node is disabled. This can happen when a clock is
+optional, provided by a separate block which never gets enabled.
+
+One example of this happening is the rk3588's VOP, which has optional
+additional display clocks coming from PLLs inside the hdmiphy blocks.
+These can be used for better rates, but the system will also work
+without them.
+
+The problem around that is described in the followups to[1]. As we
+already know the of node of the presumed clock provider, add a check via
+of_device_is_available() whether this is a "valid" device node. This
+prevents eternal defer loops.

+Subject: crypto: lib/Kconfig - Fix lib built-in failure when arch is modular
+
+From: Herbert Xu <herbert@gondor.apana.org.au>
+
+[ Upstream commit 1047e21aecdf17c8a9ab9fd4bd24c6647453f93d ]
+
+The HAVE_ARCH Kconfig options in lib/crypto try to solve the
+modular versus built-in problem, but it still fails when the
+the LIB option (e.g., CRYPTO_LIB_CURVE25519) is selected externally.
+
+Fix this by introducing a level of indirection with ARCH_MAY_HAVE
+Kconfig options, these then go on to select the ARCH_HAVE options
+if the ARCH Kconfig options matches that of the LIB option.

+Subject: dmaengine: dmatest: Fix dmatest waiting less when interrupted
+
+From: Vinicius Costa Gomes <vinicius.gomes@intel.com>
+
+[ Upstream commit e87ca16e99118ab4e130a41bdf12abbf6a87656c ]
+
+Change the "wait for operation finish" logic to take interrupts into
+account.
+
+When using dmatest with idxd DMA engine, it's possible that during
+longer tests, the interrupt notifying the finish of an operation
+happens during wait_event_freezable_timeout(), which causes dmatest to
+cleanup all the resources, some of which might still be in use.
+
+This fix ensures that the wait logic correctly handles interrupts,
+preventing premature cleanup of resources.

+Subject: drm/amdgpu: Increase KIQ invalidate_tlbs timeout
+
+From: Jay Cornwall <jay.cornwall@amd.com>
+
+[ Upstream commit 3666ed821832f42baaf25f362680dda603cde732 ]
+
+KIQ invalidate_tlbs request has been seen to marginally exceed the
+configured 100 ms timeout on systems under load.
+
+All other KIQ requests in the driver use a 10 second timeout. Use a
+similar timeout implementation on the invalidate_tlbs path.

+
+[ Upstream commit c235a7132258ac30bd43d228222986022d21f5de ]
+
+There are a few prechecks made before HDP flush like a flush is not
+required on APU bare metal. Using hdp callback directly bypasses those
+checks. Use amdgpu_device_flush_hdp which takes care of prechecks.

+Subject: ext4: make block validity check resistent to sb bh corruption
+
+From: Ojaswin Mujoo <ojaswin@linux.ibm.com>
+
+[ Upstream commit ccad447a3d331a239477c281533bacb585b54a98 ]
+
+Block validity checks need to be skipped in case they are called
+for journal blocks since they are part of system's protected
+zone.
+
+Currently, this is done by checking inode->ino against
+sbi->s_es->s_journal_inum, which is a direct read from the ext4 sb
+buffer head. If someone modifies this underneath us then the
+s_journal_inum field might get corrupted. To prevent against this,
+change the check to directly compare the inode with journal->j_inode.
+
+**Slight change in behavior**: During journal init path,
+check_block_validity etc might be called for journal inode when
+sbi->s_journal is not set yet. In this case we now proceed with
+ext4_inode_block_valid() instead of returning early. Since systems zones
+have not been set yet, it is okay to proceed so we can perform basic
+checks on the blocks.

+Subject: fs/ntfs3: Fix WARNING in ntfs_extend_initialized_size
+
+From: Edward Adam Davis <eadavis@qq.com>
+
+[ Upstream commit ff355926445897cc9fdea3b00611e514232c213c ]
+
+Syzbot reported a WARNING in ntfs_extend_initialized_size.
+The data type of in->i_valid and to is u64 in ntfs_file_mmap().
+If their values are greater than LLONG_MAX, overflow will occur because
+the data types of the parameters valid and new_valid corresponding to
+the function ntfs_extend_initialized_size() are loff_t.
+
+Before calling ntfs_extend_initialized_size() in the ntfs_file_mmap(),
+the "ni->i_valid < to" has been determined, so the same WARN_ON determination
+is not required in ntfs_extend_initialized_size().
+Just execute the ntfs_extend_initialized_size() in ntfs_extend() to make
+a WARN_ON check.

+Subject: fs/ntfs3: Keep write operations atomic
+
+From: Lizhi Xu <lizhi.xu@windriver.com>
+
+[ Upstream commit 285cec318bf5a7a6c8ba999b2b6ec96f9a20590f ]
+
+syzbot reported a NULL pointer dereference in __generic_file_write_iter. [1]
+
+Before the write operation is completed, the user executes ioctl[2] to clear
+the compress flag of the file, which causes the is_compressed() judgment to
+return 0, further causing the program to enter the wrong process and call the
+wrong ops ntfs_aops_cmpr, which triggers the null pointer dereference of
+write_begin.
+
+Use inode lock to synchronize ioctl and write to avoid this case.

+In iomap_adjust_read_range, i is either the first !uptodate block, or it
+is past last for the second loop looking for trailing uptodate blocks.
+Assuming there's no overflow (there's no combination of huge folios and

+Subject: iommu: Clear iommu-dma ops on cleanup
+
+From: Robin Murphy <robin.murphy@arm.com>
+
+[ Upstream commit 280e5a30100578106a4305ce0118e0aa9b866f12 ]
+
+If iommu_device_register() encounters an error, it can end up tearing
+down already-configured groups and default domains, however this
+currently still leaves devices hooked up to iommu-dma (and even
+historically the behaviour in this area was at best inconsistent across
+architectures/drivers...) Although in the case that an IOMMU is present
+whose driver has failed to probe, users cannot necessarily expect DMA to
+work anyway, it's still arguable that we should do our best to put
+things back as if the IOMMU driver was never there at all, and certainly
+the potential for crashing in iommu-dma itself is undesirable. Make sure
+we clean up the dev->dma_iommu flag along with everything else.

+Subject: mailbox: pcc: Always clear the platform ack interrupt first
+
+From: Sudeep Holla <sudeep.holla@arm.com>
+
+[ Upstream commit cf1338c0e02880cd235a4590eeb15e2039c873bc ]
+
+The PCC mailbox interrupt handler (pcc_mbox_irq()) currently checks
+for command completion flags and any error status before clearing the
+interrupt.
+
+The below sequence highlights an issue in the handling of PCC mailbox
+interrupts, specifically when dealing with doorbell notifications and
+acknowledgment between the OSPM and the platform where type3 and type4
+channels are sharing the interrupt.
+
+-------------------------------------------------------------------------
+| T | Platform Firmware | OSPM/Linux PCC driver |
+|---|---------------------------------|---------------------------------|
+| 1 | | Build message in shmem |
+| 2 | | Ring Type3 chan doorbell |
+| 3 | Receives the doorbell interrupt | |
+| 4 | Process the message from OSPM | |
+| 5 | Build response for the message | |
+| 6 | Ring Platform ACK interrupt on | |
+| | Type3 chan to OSPM | Received the interrupt |
+| 7 | Build Notification in Type4 Chan| |
+| 8 | | Start processing interrupt in |
+| | | pcc_mbox_irq() handler |
+| 9 | | Enter PCC handler for Type4 chan|
+|10 | | Check command complete cleared |
+|11 | | Read the notification |
+|12 | | Clear Platform ACK interrupt |
+| | No effect from the previous step yet as the Platform ACK |
+| | interrupt has not yet been triggered for this channel |
+|13 | Ring Platform ACK interrupt on | |
+| | Type4 chan to OSPM | |
+|14 | | Enter PCC handler for Type3 chan|
+|15 | | Command complete is set. |
+|16 | | Read the response. |
+|17 | | Clear Platform ACK interrupt |
+|18 | | Leave PCC handler for Type3 |
+|19 | | Leave pcc_mbox_irq() handler |
+|20 | | Re-enter pcc_mbox_irq() handler |
+|21 | | Enter PCC handler for Type4 chan|
+|22 | | Leave PCC handler for Type4 chan|
+|23 | | Enter PCC handler for Type3 chan|
+|24 | | Leave PCC handler for Type3 chan|
+|25 | | Leave pcc_mbox_irq() handler |
+-------------------------------------------------------------------------
+
+The key issue occurs when OSPM tries to acknowledge platform ack
+interrupt for a notification which is ready to be read and processed
+but the interrupt itself is not yet triggered by the platform.
+
+This ineffective acknowledgment leads to an issue later in time where
+the interrupt remains pending as we exit the interrupt handler without
+clearing the platform ack interrupt as there is no pending response or
+notification. The interrupt acknowledgment order is incorrect.
+
+To resolve this issue, the platform acknowledgment interrupt should
+always be cleared before processing the interrupt for any notifications
+or response.

+Subject: mailbox: pcc: Fix the possible race in updation of chan_in_use flag
+
+From: Huisong Li <lihuisong@huawei.com>
+
+[ Upstream commit 9779d45c749340ab461d595c1a4a664cb28f3007 ]
+
+The function mbox_chan_received_data() calls the Rx callback of the
+mailbox client driver. The callback might set chan_in_use flag from
+pcc_send_data(). This flag's status determines whether the PCC channel
+is in use.
+
+However, there is a potential race condition where chan_in_use is
+updated incorrectly due to concurrency between the interrupt handler
+(pcc_mbox_irq()) and the command sender(pcc_send_data()).
+
+The 'chan_in_use' flag of a channel is set to true after sending a
+command. And the flag of the new command may be cleared erroneous by
+the interrupt handler afer mbox_chan_received_data() returns,
+
+As a result, the interrupt being level triggered can't be cleared in
+pcc_mbox_irq() and it will be disabled after the number of handled times
+exceeds the specified value. The error log is as follows:
+
+ | kunpeng_hccs HISI04B2:00: PCC command executed timeout!
+ | kunpeng_hccs HISI04B2:00: get port link status info failed, ret = -110
+ | irq 13: nobody cared (try booting with the "irqpoll" option)

+
+[ Upstream commit b7c178d9e57c8fd4238ff77263b877f6f16182ba ]
+
+During recovery/check operations, the process_checks function loops
+through available disks to find a 'primary' source with successfully
+read data.
+
+If no suitable source disk is found after checking all possibilities,
+the 'primary' index will reach conf->raid_disks * 2. Add an explicit
+check for this condition after the loop. If no source disk was found,
+print an error message and return early to prevent further processing
+without a valid primary source.

+Subject: ntb: reduce stack usage in idt_scan_mws
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit aff12700b8dd7422bfe2277696e192af4df9de8f ]
+
+idt_scan_mws() puts a large fixed-size array on the stack and copies
+it into a smaller dynamically allocated array at the end. On 32-bit
+targets, the fixed size can easily exceed the warning limit for
+possible stack overflow:
+
+drivers/ntb/hw/idt/ntb_hw_idt.c:1041:27: error: stack frame size (1032) exceeds limit (1024) in 'idt_scan_mws' [-Werror,-Wframe-larger-than]
+
+Change it to instead just always use dynamic allocation for the
+array from the start. It's too big for the stack, but not actually
+all that much for a permanent allocation.

+ in wcd934x_slim_irq_handler()
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 060aed9c0093b341480770457093449771cf1496 ]
+
+If 'port_id' is negative, the shift counts in wcd934x_slim_irq_handler()
+also become negative, resulting in undefined behavior due to shift out
+of bounds.
+
+If I'm reading the code correctly, that appears to be not possible, but
+with KCOV enabled, Clang's range analysis isn't always able to determine
+that and generates undefined behavior.
+
+As a result the code generation isn't optimal, and undefined behavior
+should be avoided regardless. Improve code generation and remove the
+undefined behavior by converting the signed variables to unsigned.
+
+Fixes the following warning with UBSAN:
+
+ sound/soc/codecs/snd-soc-wcd934x.o: warning: objtool: .text.wcd934x_slim_irq_handler: unexpected end of section

+Subject: objtool, lkdtm: Obfuscate the do_nothing() pointer
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 05026ea01e95ffdeb0e5ac8fb7fb1b551e3a8726 ]
+
+If execute_location()'s memcpy of do_nothing() gets inlined and unrolled
+by the compiler, it copies one word at a time:
+
+ mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x1374
+ mov %rax,0x38(%rbx)
+ mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x136c
+ mov %rax,0x30(%rbx)
+ ...
+
+Those .text references point to the middle of the function, causing
+objtool to complain about their lack of ENDBR.
+
+Prevent that by resolving the function pointer at runtime rather than
+build time. This fixes the following warning:
+
+ drivers/misc/lkdtm/lkdtm.o: warning: objtool: execute_location+0x23: relocation to !ENDBR: .text+0x1378

+Subject: objtool, regulator: rk808: Remove potential undefined behavior in
+ rk806_set_mode_dcdc()
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 29c578c848402a34e8c8e115bf66cb6008b77062 ]
+
+If 'ctr_bit' is negative, the shift counts become negative, causing a
+shift of bounds and undefined behavior.
+
+Presumably that's not possible in normal operation, but the code
+generation isn't optimal. And undefined behavior should be avoided
+regardless.
+
+Improve code generation and remove the undefined behavior by converting
+the signed variables to unsigned.
+
+Fixes the following warning with an UBSAN kernel:
+
+ vmlinux.o: warning: objtool: rk806_set_mode_dcdc() falls through to next function rk806_get_mode_dcdc()
+ vmlinux.o: warning: objtool: .text.rk806_set_mode_dcdc: unexpected end of section

+Subject: objtool: Silence more KCOV warnings
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 6b023c7842048c4bbeede802f3cf36b96c7a8b25 ]
+
+In the past there were issues with KCOV triggering unreachable
+instruction warnings, which is why unreachable warnings are now disabled
+with CONFIG_KCOV.
+
+Now some new KCOV warnings are showing up with GCC 14:
+
+ vmlinux.o: warning: objtool: cpuset_write_resmask() falls through to next function cpuset_update_active_cpus.cold()
+ drivers/usb/core/driver.o: error: objtool: usb_deregister() falls through to next function usb_match_device()
+ sound/soc/codecs/snd-soc-wcd934x.o: warning: objtool: .text.wcd934x_slim_irq_handler: unexpected end of section
+
+All are caused by GCC KCOV not finishing an optimization, leaving behind
+a never-taken conditional branch to a basic block which falls through to
+the next function (or end of section).
+
+At a high level this is similar to the unreachable warnings mentioned
+above, in that KCOV isn't fully removing dead code. Treat it the same
+way by adding these to the list of warnings to ignore with CONFIG_KCOV.

+Subject: perf/core: Fix WARN_ON(!ctx) in __free_event() for partial init
+
+From: Gabriel Shahrouzi <gshahrouzi@gmail.com>
+
+[ Upstream commit 0ba3a4ab76fd3367b9cb680cad70182c896c795c ]
+
+Move the get_ctx(child_ctx) call and the child_event->ctx assignment to
+occur immediately after the child event is allocated. Ensure that
+child_event->ctx is non-NULL before any subsequent error path within
+inherit_event calls free_event(), satisfying the assumptions of the
+cleanup code.
+
+Details:
+
+There's no clear Fixes tag, because this bug is a side-effect of
+multiple interacting commits over time (up to 15 years old), not
+a single regression.
+
+The code initially incremented refcount then assigned context
+immediately after the child_event was created. Later, an early
+validity check for child_event was added before the
+refcount/assignment. Even later, a WARN_ON_ONCE() cleanup check was
+added, assuming event->ctx is valid if the pmu_ctx is valid.
+The problem is that the WARN_ON_ONCE() could trigger after the initial
+check passed but before child_event->ctx was assigned, violating its
+precondition. The solution is to assign child_event->ctx right after
+its initial validation. This ensures the context exists for any
+subsequent checks or cleanup routines, resolving the WARN_ON_ONCE().
+
+To resolve it, defer the refcount update and child_event->ctx assignment
+directly after child_event->pmu_ctx is set but before checking if the
+parent event is orphaned. The cleanup routine depends on
+event->pmu_ctx being non-NULL before it verifies event->ctx is
+non-NULL. This also maintains the author's original intent of passing
+in child_ctx to find_get_pmu_context before its refcount/assignment.

+From: Andy Yan <andy.yan@rock-chips.com>
+
+[ Upstream commit 28dc672a1a877c77b000c896abd8f15afcdc1b0c ]

+Function rk_udphy_dp_hpd_event_trigger will set vogrf let it
+trigger HPD interrupt to DP by Type-C. This configuration is only
+required when the DP work in Alternate Mode, and called by
+typec_mux_set. In standard DP mode, such settings will prevent

+Subject: pinctrl: mcp23s08: Get rid of spurious level interrupts
+
+From: Dmitry Mastykin <mastichi@gmail.com>
+
+[ Upstream commit 7b0671b97f0872d6950ccc925e210cb3f67721bf ]
+
+irq_mask()/irq_unmask() are not called for nested interrupts. So level
+interrupts are never masked, chip's interrupt output is not cleared on
+INTCAP or GPIO read, the irq handler is uselessly called again. Nested
+irq handler is not called again, because interrupt reason is cleared by
+its first call.
+/proc/interrupts shows that number of chip's irqs is greater than
+number of nested irqs.
+
+This patch adds masking and unmasking level interrupts inside irq handler.

+
+Power-on Reset has a documented issue in PCF85063, refer to its datasheet,
+section "Software reset":
+
+"There is a low probability that some devices will have corruption of the
+registers after the automatic power-on reset if the device is powered up
+with a residual VDD level. It is required that the VDD starts at zero volts
+at power up or upon power cycling to ensure that there is no corruption of
+the registers. If this is not possible, a reset must be initiated after
+power-up (i.e. when power is stable) with the software reset command"
+
+Trigger SW reset if there is an indication that POR has failed.

+Subject: scsi: hisi_sas: Fix I/O errors caused by hardware port ID changes
+
+From: Xingui Yang <yangxingui@huawei.com>
+
+[ Upstream commit daff37f00c7506ca322ccfce95d342022f06ec58 ]
+
+The hw port ID of phy may change when inserting disks in batches, causing
+the port ID in hisi_sas_port and itct to be inconsistent with the hardware,
+resulting in I/O errors. The solution is to set the device state to gone to
+intercept I/O sent to the device, and then execute linkreset to discard and
+find the disk to re-update its information.

+Subject: selftests/bpf: Fix stdout race condition in traffic monitor
+
+From: Amery Hung <ameryhung@gmail.com>
+
+[ Upstream commit b99f27e90268b1a814c13f8bd72ea1db448ea257 ]
+
+Fix a race condition between the main test_progs thread and the traffic
+monitoring thread. The traffic monitor thread tries to print a line
+using multiple printf and use flockfile() to prevent the line from being
+torn apart. Meanwhile, the main thread doing io redirection can reassign
+or close stdout when going through tests. A deadlock as shown below can
+happen.
+
+ main traffic_monitor_thread
+ ==== ======================
+ show_transport()
+ -> flockfile(stdout)
+
+stdio_hijack_init()
+-> stdout = open_memstream(log_buf, log_cnt);
+ ...
+ env.subtest_state->stdout_saved = stdout;
+
+ ...
+ funlockfile(stdout)
+stdio_restore_cleanup()
+-> fclose(env.subtest_state->stdout_saved);
+
+After the traffic monitor thread lock stdout, A new memstream can be
+assigned to stdout by the main thread. Therefore, the traffic monitor
+thread later will not be able to unlock the original stdout. As the
+main thread tries to access the old stdout, it will hang indefinitely
+as it is still locked by the traffic monitor thread.
+
+The deadlock can be reproduced by running test_progs repeatedly with
+traffic monitor enabled:
+
+for ((i=1;i<=100;i++)); do
+ ./test_progs -a flow_dissector_skb* -m '*'
+done
+
+Fix this by only calling printf once and remove flockfile()/funlockfile().

+Subject: selftests/mincore: Allow read-ahead pages to reach the end of the
+ file
+
+From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>
+
+[ Upstream commit 197c1eaa7ba633a482ed7588eea6fd4aa57e08d4 ]
+
+When running the mincore_selftest on a system with an XFS file system, it
+failed the "check_file_mmap" test case due to the read-ahead pages reaching
+the end of the file. The failure log is as below:
+
+ RUN global.check_file_mmap ...
+ mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024)
+ mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file
+ check_file_mmap: Test failed
+ FAIL global.check_file_mmap
+
+This is because the read-ahead window size of the XFS file system on this
+machine is 4 MB, which is larger than the size from the #PF address to the
+end of the file. As a result, all the pages for this file are populated.
+
+ blockdev --getra /dev/nvme0n1p5
+ 8192
+ blockdev --getbsz /dev/nvme0n1p5
+ 512
+
+This issue can be fixed by extending the current FILE_SIZE 4MB to a larger
+number, but it will still fail if the read-ahead window size of the file
+system is larger enough. Additionally, in the real world, read-ahead pages
+reaching the end of the file can happen and is an expected behavior.
+Therefore, allowing read-ahead pages to reach the end of the file is a
+better choice for the "check_file_mmap" test case.

+Subject: sound/virtio: Fix cancel_sync warnings on uninitialized work_structs
+
+From: John Stultz <jstultz@google.com>
+
+[ Upstream commit 3c7df2e27346eb40a0e86230db1ccab195c97cfe ]
+
+Betty reported hitting the following warning:
+
+[ 8.709131][ T221] WARNING: CPU: 2 PID: 221 at kernel/workqueue.c:4182
+...

+[ 8.714139][ T221] really_probe+0x1bc/0x4c8
+...
+
+It seems we're hitting the error path in virtsnd_probe(), which
+triggers a virtsnd_remove() which iterates over the substreams
+calling cancel_work_sync() on the elapsed_period work_struct.
+
+Looking at the code, from earlier in:
+virtsnd_probe()->virtsnd_build_devs()->virtsnd_pcm_parse_cfg()
+
+We set snd->nsubstreams, allocate the snd->substreams, and if
+we then hit an error on the info allocation or something in
+virtsnd_ctl_query_info() fails, we will exit without having
+initialized the elapsed_period work_struct.
+
+When that error path unwinds we then call virtsnd_remove()
+which as long as the substreams array is allocated, will iterate
+through calling cancel_work_sync() on the uninitialized work
+struct hitting this warning.
+
+Takashi Iwai suggested this fix, which initializes the substreams
+structure right after allocation, so that if we hit the error
+paths we avoid trying to cleanup uninitialized data.
+
+Note: I have not yet managed to reproduce the issue myself, so
+this patch has had limited testing.
+
+Feedback or thoughts would be appreciated!

+Subject: spi: tegra210-quad: add rate limiting and simplify timeout error
+ message
+
+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit 21f4314e66ed8d40b2ee24185d1a06a07a512eb1 ]
+
+On malfunctioning hardware, timeout error messages can appear thousands
+of times, creating unnecessary system pressure and log bloat. This patch
+makes two improvements:
+
+1. Replace dev_err() with dev_err_ratelimited() to prevent log flooding
+ when hardware errors persist
+2. Remove the redundant timeout value parameter from the error message,
+ as 'ret' is always zero in this error path
+
+These changes reduce logging overhead while maintaining necessary error
+reporting for debugging purposes.

+Subject: spi: tegra210-quad: use WARN_ON_ONCE instead of WARN_ON for timeouts
+
+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit 41c721fc093938745d116c3a21326a0ee03bb491 ]
+
+Some machines with tegra_qspi_combined_seq_xfer hardware issues generate
+excessive kernel warnings, severely polluting the logs:
+
+ dmesg | grep -i "WARNING:.*tegra_qspi_transfer_one_message" | wc -l
+ 94451
+
+This patch replaces WARN_ON with WARN_ON_ONCE for timeout conditions to
+reduce log spam. The subsequent error message still prints on each
+occurrence, providing sufficient information about the failure, while
+the stack trace is only needed once for debugging purposes.

+Subject: thunderbolt: Scan retimers after device router has been enumerated
+
+From: Mika Westerberg <mika.westerberg@linux.intel.com>
+
+[ Upstream commit 75749d2c1d8cef439f8b69fa1f4f36d0fc3193e6 ]
+
+Thomas reported connection issues on AMD system with Pluggable UD-4VPD
+dock. After some experiments it looks like the device has some sort of
+internal timeout that triggers reconnect. This is completely against the
+USB4 spec, as there is no requirement for the host to enumerate the
+device right away or even at all.
+
+In Linux case the delay is caused by scanning of retimers on the link so
+we can work this around by doing the scanning after the device router
+has been enumerated.

+Subject: timekeeping: Add a lockdep override in tick_freeze()
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+[ Upstream commit 92e250c624ea37fde64bfd624fd2556f0d846f18 ]
+
+tick_freeze() acquires a raw spinlock (tick_freeze_lock). Later in the
+callchain (timekeeping_suspend() -> mc146818_avoid_UIP()) the RTC driver
+acquires a spinlock which becomes a sleeping lock on PREEMPT_RT. Lockdep
+complains about this lock nesting.
+
+Add a lockdep override for this special case and a comment explaining
+why it is okay.

+ volatile char above[4] = { }; /* Protect surrounding memory. */
+ volatile int arr[4];
+ volatile char below[4] = { }; /* Protect surrounding memory. */
+
+There is another problem where the out-of-bound index is 5 which is larger
+than the extra surrounding memory for protection.
+
+So, use a struct to enforce the ordering, and fix the index to be 4.
+Also, remove some of the volatiles and rely on OPTIMIZER_HIDE_VAR()

+
+From: Benjamin Berg <benjamin.berg@intel.com>
+
+[ Upstream commit 887c5c12e80c8424bd471122d2e8b6b462e12874 ]
+
+sched_yield by a userspace may not actually cause scheduling in
+time-travel mode as no time has passed. In the case seen it appears to
+be a badly implemented userspace spinlock in ASAN. Unfortunately, with
+time-travel it causes an extreme slowdown or even deadlock depending on
+the kernel configuration (CONFIG_UML_MAX_USERSPACE_ITERATIONS).
+
+Work around it by accounting time to the process whenever it executes a
+sched_yield syscall.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
+
+[ Upstream commit 461f24bff86808ee5fbfe74751a825f8a7ab24e0 ]
+
+Intel Merrifield SoC uses these endpoints for tracing and they cannot
+be re-allocated if being used because the side band flow control signals
+are hard wired to certain endpoints:
+
+• 1 High BW Bulk IN (IN#1) (RTIT)
+• 1 1KB BW Bulk IN (IN#8) + 1 1KB BW Bulk OUT (Run Control) (OUT#8)
+
+In device mode, since RTIT (EP#1) and EXI/RunControl (EP#8) uses
+External Buffer Control (EBC) mode, these endpoints are to be mapped to
+EBC mode (to be done by EXI target driver). Additionally TRB for RTIT
+and EXI are maintained in STM (System Trace Module) unit and the EXI
+target driver will as well configure the TRB location for EP #1 IN
+and EP#8 (IN and OUT). Since STM/PTI and EXI hardware blocks manage
+these endpoints and interface to OTG3 controller through EBC interface,
+there is no need to enable any events (such as XferComplete etc)
+for these end points.

+Subject: usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev()
+
+From: Chenyuan Yang <chenyuan0y@gmail.com>
+
+[ Upstream commit 8c75f3e6a433d92084ad4e78b029ae680865420f ]
+
+The variable d->name, returned by devm_kasprintf(), could be NULL.
+A pointer check is added to prevent potential NULL pointer dereference.
+This is similar to the fix in commit 3027e7b15b02
+("ice: Fix some null pointer dereference issues in ice_ptp.c").
+
+This issue is found by our static analysis tool

+Subject: usb: xhci: Fix isochronous Ring Underrun/Overrun event handling
+
+From: Michal Pecio <michal.pecio@gmail.com>
+
+[ Upstream commit 906dec15b9b321b546fd31a3c99ffc13724c7af4 ]
+
+The TRB pointer of these events points at enqueue at the time of error
+occurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time we
+are handling the event, a new TD may be queued at this ring position.
+
+I can trigger this race by rising interrupt moderation to increase IRQ
+handling delay. Similar delay may occur naturally due to system load.
+
+If this ever happens after a Missed Service Error, missed TDs will be
+skipped and the new TD processed as if it matched the event. It could
+be given back prematurely, risking data loss or buffer UAF by the xHC.
+
+Don't complete TDs on xrun events and don't warn if queued TDs don't
+match the event's TRB pointer, which can be NULL or a link/no-op TRB.
+Don't warn if there are no queued TDs at all.
+
+Now that it's safe, also handle xrun events if the skip flag is clear.
+This ensures completion of any TD stuck in 'error mid TD' state right
+before the xrun event, which could happen if a driver submits a finite
+number of URBs to a buggy HC and then an error occurs on the last TD.

+Subject: x86/bugs: Don't fill RSB on context switch with eIBRS
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 27ce8299bc1ec6df8306073785ff82b30b3cc5ee ]
+
+User->user Spectre v2 attacks (including RSB) across context switches
+are already mitigated by IBPB in cond_mitigation(), if enabled globally
+or if either the prev or the next task has opted in to protection. RSB
+filling without IBPB serves no purpose for protecting user space, as
+indirect branches are still vulnerable.
+
+User->kernel RSB attacks are mitigated by eIBRS. In which case the RSB
+filling on context switch isn't needed, so remove it.

+Subject: x86/bugs: Don't fill RSB on VMEXIT with eIBRS+retpoline
+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit 18bae0dfec15b24ec14ca17dc18603372f5f254f ]
+
+eIBRS protects against guest->host RSB underflow/poisoning attacks.
+Adding retpoline to the mix doesn't change that. Retpoline has a
+balanced CALL/RET anyway.
+
+So the current full RSB filling on VMEXIT with eIBRS+retpoline is
+overkill. Disable it or do the VMEXIT_LITE mitigation if needed.

+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit fc9fd3f98423367c79e0bd85a9515df26dc1b3cc ]
+
+write_ibpb() does IBPB, which (among other things) flushes branch type
+predictions on AMD. If the CPU has SRSO_NO, or if the SRSO mitigation
+has been disabled, branch type flushing isn't needed, in which case the
+lighter-weight SBPB can be used.
+
+The 'x86_pred_cmd' variable already keeps track of whether IBPB or SBPB
+should be used. Use that instead of hardcoding IBPB.

+Subject: x86/i8253: Call clockevent_i8253_disable() with interrupts disabled
+
+From: Fernando Fernandez Mancera <ffmancera@riseup.net>
+
+[ Upstream commit 3940f5349b476197fb079c5aa19c9a988de64efb ]
+
+There's a lockdep false positive warning related to i8253_lock:
+
+ WARNING: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected
+ ...
+ systemd-sleep/3324 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
+ ffffffffb2c23398 (i8253_lock){+.+.}-{2:2}, at: pcspkr_event+0x3f/0xe0 [pcspkr]

+ ... which became HARDIRQ-irq-unsafe at:

+
+Lockdep complains due pit_timer_init() using the lock in an IRQ-unsafe
+fashion, but it's a false positive, because there is no deadlock
+possible at that point due to init ordering: at the point where
+pit_timer_init() is called there is no other possible usage of
+i8253_lock because the system is still in the very early boot stage
+with no interrupts.
+
+But in any case, pit_timer_init() should disable interrupts before
+calling clockevent_i8253_disable() out of general principle, and to
+keep lockdep working even in this scenario.
+
+Use scoped_guard() for that, as suggested by Thomas Gleixner.

+Subject: x86/Kconfig: Make CONFIG_PCI_CNB20LE_QUIRK depend on X86_32
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Mateusz Jończyk <mat.jonczyk@o2.pl>
+
+[ Upstream commit d9f87802676bb23b9425aea8ad95c76ad9b50c6e ]
+
+I was unable to find a good description of the ServerWorks CNB20LE
+chipset. However, it was probably exclusively used with the Pentium III
+processor (this CPU model was used in all references to it that I
+found where the CPU model was provided: dmesgs in [1] and [2];
+[3] page 2; [4]-[7]).
+
+As is widely known, the Pentium III processor did not support the 64-bit
+mode, support for which was introduced by Intel a couple of years later.
+So it is safe to assume that no systems with the CNB20LE chipset have
+amd64 and the CONFIG_PCI_CNB20LE_QUIRK may now depend on X86_32.
+
+Additionally, I have determined that most computers with the CNB20LE
+chipset did have ACPI support and this driver was inactive on them.
+I have submitted a patch to remove this driver, but it was met with
+resistance [8].

+Subject: x86/xen: disable CPU idle and frequency drivers for PVH dom0
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Roger Pau Monne <roger.pau@citrix.com>
+
+[ Upstream commit 64a66e2c3b3113dc78a6124e14825d68ddc2e188 ]
+
+When running as a PVH dom0 the ACPI tables exposed to Linux are (mostly)
+the native ones, thus exposing the C and P states, that can lead to
+attachment of CPU idle and frequency drivers. However the entity in
+control of the CPU C and P states is Xen, as dom0 doesn't have a full view
+of the system load, neither has all CPUs assigned and identity pinned.
+
+Like it's done for classic PV guests, prevent Linux from using idle or
+frequency state drivers when running as a PVH dom0.
+
+On an AMD EPYC 7543P system without this fix a Linux PVH dom0 will keep the
+host CPUs spinning at 100% even when dom0 is completely idle, as it's
+attempting to use the acpi_idle driver.

+
+Etron xHC generates two transfer events for the TRB if an error is
+detected while processing the last TRB of an isoc TD.
+
+The first event can be any sort of error (like USB Transaction or
+Babble Detected, etc), and the final event is Success.
+
+The xHCI driver will handle the TD after the first event and remove it
+from its internal list, and then print an "Transfer event TRB DMA ptr
+not part of current TD" error message after the final event.
+
+Commit 5372c65e1311 ("xhci: process isoc TD properly when there was a
+transaction error mid TD.") is designed to address isoc transaction
+errors, but unfortunately it doesn't account for this scenario.
+
+This issue is similar to the XHCI_SPURIOUS_SUCCESS case where a success
+event follows a 'short transfer' event, but the TD the event points to
+is already given back.
+
+Expand the spurious success 'short transfer' event handling to cover
+the spurious success after error on Etron hosts.
+
+Kuangyi Chiang reported this issue and submitted a different solution
+based on using error_mid_td. This commit message is mostly taken
+from that patch.
