The above issue occurs with us in errors=continue mode when accompanied by storage failures. There have been many inconsistencies in the file system data.
In the case of file system data inconsistency, for example, if the block bitmap of a referenced block is not set, it can lead to the situation where a block being committed is allocated and used again. As a result, the following condition will not be satisfied then trigger BUG_ON. Of course, it is entirely possible to construct a problematic image that can trigger this BUG_ON through specific operations. In fact, I have constructed such an image and easily reproduced this issue.
Therefore, J_ASSERT() holds true only under ideal conditions, but it may not necessarily be satisfied in exceptional scenarios. Using J_ASSERT() directly in abnormal situations would cause the system to crash, which is clearly not what we want. So here we directly trigger a JBD abort instead of immediately invoking BUG_ON.

PATCH 3/60 ext4: refresh inline data size before write operations

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Deepanshu Kartikey <[email protected]>

commit 892e1cf17555735e9d021ab036c36bc7b58b0e3b upstream.

The cached ei->i_inline_size can become stale between the initial size check and when ext4_update_inline_data()/ext4_create_inline_data() use it. Although ext4_get_max_inline_size() reads the correct value at the time of the check, concurrent xattr operations can modify i_inline_size before ext4_write_lock_xattr() is acquired.

This causes ext4_update_inline_data() and ext4_create_inline_data() to work with stale capacity values, leading to a BUG_ON() crash in ext4_write_inline_data():

kernel BUG at fs/ext4/inline.c:1331! BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);

The race window:
1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct)
2. Size check passes for 50-byte write
3. [Another thread adds xattr, i_inline_size changes to 40]
4. ext4_write_lock_xattr() acquires lock
5. ext4_update_inline_data() uses stale i_inline_size = 60
6. Attempts to write 50 bytes but only 40 bytes actually available
7. BUG_ON() triggers

Fix this by recalculating i_inline_size via ext4_find_inline_data_nolock() immediately after acquiring xattr_sem. This ensures ext4_update_inline_data() and ext4_create_inline_data() work with current values that are protected from concurrent modifications.

This is similar to commit a54c4613dac1 ("ext4: fix race writing to an inline_data file while its xattrs are changing") which fixed i_inline_off staleness. This patch addresses the related i_inline_size staleness issue.

PATCH 4/60 ksmbd: ipc: fix use-after-free in ipc_msg_send_request

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Qianchang Zhao <[email protected]>

commit 1fab1fa091f5aa97265648b53ea031deedd26235 upstream.

ipc_msg_send_request() waits for a generic netlink reply using an ipc_msg_table_entry on the stack. The generic netlink handler (handle_generic_event()/handle_response()) fills entry->response under ipc_msg_table_lock, but ipc_msg_send_request() used to validate and free entry->response without holding the same lock.

Under high concurrency this allows a race where handle_response() is copying data into entry->response while ipc_msg_send_request() has just freed it, leading to a slab-use-after-free reported by KASAN in handle_generic_event():

  BUG: KASAN: slab-use-after-free in handle_generic_event+0x3c4/0x5f0 [ksmbd]

- Taking ipc_msg_table_lock in ipc_msg_send_request() while validating entry->response, freeing it when invalid, and removing the entry from ipc_msg_table.
- Returning the final entry->response pointer to the caller only after the hash entry is removed under the lock.
- Returning NULL in the error path, preserving the original API semantics.

This makes all accesses to entry->response consistent with handle_response(), which already updates and fills the response buffer under ipc_msg_table_lock, and closes the race that allowed the UAF.

PATCH 5/60 locking/spinlock/debug: Fix data-race in do_raw_write_lock

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alexander Sverdlin <[email protected]>

commit c14ecb555c3ee80eeb030a4e46d00e679537f03a upstream.

KCSAN reports:

BUG: KCSAN: data-race in do_raw_write_lock / do_raw_write_lock

write (marked) to 0xffff800009cf504c of 4 bytes by task 1102 on cpu 1:

value changed: 0xffffffff -> 0x00000001

Reported by Kernel Concurrency Sanitizer on:

CPU: 0 PID: 1103 Comm: kworker/u4:1 6.1.111

Commit 1a365e822372 ("locking/spinlock/debug: Fix various data races") has adressed most of these races, but seems to be not consistent/not complete.

Quoted 1 line

From do_raw_write_lock() only debug_write_lock_after() part has been

converted to WRITE_ONCE(), but not debug_write_lock_before() part. Do it now.

PATCH 6/60 crypto: zstd - fix double-free in per-CPU stream cleanup

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Giovanni Cabiddu <[email protected]>

commit 48bc9da3c97c15f1ea24934bcb3b736acd30163d upstream.

The crypto/zstd module has a double-free bug that occurs when multiple tfms are allocated and freed.

The issue happens because zstd_streams (per-CPU contexts) are freed in zstd_exit() during every tfm destruction, rather than being managed at the module level. When multiple tfms exist, each tfm exit attempts to free the same shared per-CPU streams, resulting in a double-free.

This leads to a stack trace similar to:

PATCH 7/60 ext4: add i_data_sem protection in ext4_destroy_inline_data_nolock()

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alexey Nepomnyashih <[email protected]>

commit 0cd8feea8777f8d9b9a862b89c688b049a5c8475 upstream.

Fix a race between inline data destruction and block mapping.

The function ext4_destroy_inline_data_nolock() changes the inode data layout by clearing EXT4_INODE_INLINE_DATA and setting EXT4_INODE_EXTENTS. At the same time, another thread may execute ext4_map_blocks(), which tests EXT4_INODE_EXTENTS to decide whether to call ext4_ext_map_blocks() or ext4_ind_map_blocks().

Without i_data_sem protection, ext4_ind_map_blocks() may receive inode with EXT4_INODE_EXTENTS flag and triggering assert.

PATCH 8/60 comedi: pcl818: fix null-ptr-deref in pcl818_ai_cancel()

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nikita Zhandarovich <[email protected]>

commit a51f025b5038abd3d22eed2ede4cd46793d89565 upstream.

Syzbot identified an issue [1] in pcl818_ai_cancel(), which stems from the fact that in case of early device detach via pcl818_detach(), subdevice dev->read_subdev may not have initialized its pointer to &struct comedi_async as intended. Thus, any such dereferencing of &s->async->cmd will lead to general protection fault and kernel crash.

Mitigate this problem by removing a call to pcl818_ai_cancel() from pcl818_detach() altogether. This way, if the subdevice setups its support for async commands, everything async-related will be handled via subdevice's own ->cancel() function in comedi_device_detach_locked() even before pcl818_detach(). If no support for asynchronous commands is provided, there is no need to cancel anything either.

[1] Syzbot crash:

PATCH 9/60 KVM: SVM: Dont skip unrelated instruction if INT3/INTO is replaced

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Omar Sandoval <[email protected]>

commit 4da3768e1820cf15cced390242d8789aed34f54d upstream.

When re-injecting a soft interrupt from an INT3, INT0, or (select) INTn instruction, discard the exception and retry the instruction if the code stream is changed (e.g. by a different vCPU) between when the CPU executes the instruction and when KVM decodes the instruction to get the next RIP.

As effectively predicted by commit 6ef88d6e36c2 ("KVM: SVM: Re-inject INT3/INTO instead of retrying the instruction"), failure to verify that the correct INTn instruction was decoded can effectively clobber guest state due to decoding the wrong instruction and thus specifying the wrong next RIP.

The bug most often manifests as "Oops: int3" panics on static branch checks in Linux guests. Enabling or disabling a static branch in Linux uses the kernel's "text poke" code patching mechanism. To modify code while other CPUs may be executing that code, Linux (temporarily) replaces the first byte of the original instruction with an int3 (opcode 0xcc), then patches in the new code stream except for the first byte, and finally replaces the int3 with the first byte of the new code stream. If a CPU hits the int3, i.e. executes the code while it's being modified, then the guest kernel must look up the RIP to determine how to handle the #BP, e.g. by emulating the new instruction. If the RIP is incorrect, then this lookup fails and the guest kernel panics.

The bug reproduces almost instantly by hacking the guest kernel to repeatedly check a static branch[1] while running a drgn script[2] on the host to constantly swap out the memory containing the guest's TSS.

PATCH 13/60 USB: serial: ftdi_sio: match on interface number for jtag

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Johan Hovold <[email protected]>

commit 4e31a5d0a9ee672f708fc993c1d5520643f769fd upstream.

Some FTDI devices have the first port reserved for JTAG and have been using a dedicated quirk to prevent binding to it.

As can be inferred directly or indirectly from the commit messages, almost all of these devices are dual port devices which means that the more recently added macro for matching on interface number can be used instead (and some such devices do so already).

This avoids probing interfaces that will never be bound and cleans up the match table somewhat.

Note that the JTAG quirk is kept for quad port devices, which would otherwise require three match entries.

PATCH 14/60 serial: add support of CPCI cards

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Magne Bruno <[email protected]>

commit 0e5a99e0e5f50353b86939ff6e424800d769c818 upstream.

Addi-Data GmbH is manufacturing multi-serial ports cards supporting CompactPCI (known as CPCI). Those cards are identified with different DeviceIds. Those cards integrating standard UARTs work the same way as PCI/PCIe models already supported in the serial driver.

PATCH 19/60 ftrace: bpf: Fix IPMODIFY + DIRECT in modify_ftrace_direct()

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Song Liu <[email protected]>

[ Upstream commit 3e9a18e1c3e931abecf501cbb23d28d69f85bb56 ]

ftrace_hash_ipmodify_enable() checks IPMODIFY and DIRECT ftrace_ops on the same kernel function. When needed, ftrace_hash_ipmodify_enable() calls ops->ops_func() to prepare the direct ftrace (BPF trampoline) to share the same function as the IPMODIFY ftrace (livepatch).

ftrace_hash_ipmodify_enable() is called in register_ftrace_direct() path, but not called in modify_ftrace_direct() path. As a result, the following operations will break livepatch:

1. Load livepatch to a kernel function;
2. Attach fentry program to the kernel function;
3. Attach fexit program to the kernel function.

After 3, the kernel function being used will not be the livepatched version, but the original version.

Fix this by adding __ftrace_hash_update_ipmodify() to __modify_ftrace_direct() and adjust some logic around the call.

PATCH 20/60 spi: xilinx: increase number of retries before declaring stall

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alvaro Gamez Machado <[email protected]>

[ Upstream commit 939edfaa10f1d22e6af6a84bf4bd96dc49c67302 ]

SPI devices using a (relative) slow frequency need a larger time.

For instance, microblaze running at 83.25MHz and performing a 3 bytes transaction using a 10MHz/16 = 625kHz needed this stall value increased to at least 20. The SPI device is quite slow, but also is the microblaze, so set this value to 32 to give it even more margin.

PATCH 21/60 spi: imx: keep dma request disabled before dma transfer setup

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Robin Gong <[email protected]>

[ Upstream commit 86d57d9c07d54e8cb385ffe800930816ccdba0c1 ]

Since sdma hardware configure postpone to transfer phase, have to disable dma request before dma transfer setup because there is a hardware limitation on sdma event enable(ENBLn) as below:

"It is thus essential for the Arm platform to program them before any DMA
request is triggered to the SDMA, otherwise an unpredictable combination of channels may be started."

PATCH 22/60 ACPI: MRRM: Fix memory leaks and improve error handling

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kaushlendra Kumar <[email protected]>

[ Upstream commit 4b93d211bbffd3dce76664d95f2306d23e7215ce ]

Add proper error handling and resource cleanup to prevent memory leaks in add_boot_memory_ranges(). The function now checks for NULL return from kobject_create_and_add(), uses local buffer for range names to avoid dynamic allocation, and implements a cleanup path that removes previously created sysfs groups and kobjects on failure.

This prevents resource leaks when kobject creation or sysfs group creation fails during boot memory range initialization.

PATCH 26/60 Bluetooth: btrtl: Avoid loading the config file on security chips

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Max Chou <[email protected]>

[ Upstream commit cd8dbd9ef600435439bb0e70af0a1d9e2193aecb ]

For chips with security enabled, it's only possible to load firmware with a valid signature pattern.
If key_id is not zero, it indicates a security chip, and the driver will not load the config file.

- Example log for a security chip.

Bluetooth: hci0: RTL: examining hci_ver=0c hci_rev=000a
lmp_ver=0c lmp_subver=8922
Bluetooth: hci0: RTL: rom_version status=0 version=1

PATCH 27/60 ASoC: SDCA: bug fix while parsing mipi-sdca-control-cn-list

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Niranjan H Y <[email protected]>

[ Upstream commit eb2d6774cc0d9d6ab8f924825695a85c14b2e0c2 ]

"struct sdca_control" declares "values" field as integer array. But the memory allocated to it is of char array. This causes crash for sdca_parse_function API. This patch addresses the issue by allocating correct data size.

PATCH 29/60 drm/amdkfd: Fix GPU mappings for APU after prefetch

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Harish Kasiviswanathan <[email protected]>

[ Upstream commit eac32ff42393efa6657efc821231b8d802c1d485 ]

Fix the following corner case:-
Consider a 2M huge page SVM allocation, followed by prefetch call for
the first 4K page. The whole range is initially mapped with single PTE. After the prefetch, this range gets split to first page + rest of the pages. Currently, the first page mapping is not updated on MI300A (APU) since page hasn't migrated. However, after range split PTE mapping it not valid.

Fix this by forcing page table update for the whole range when prefetch is called. Calling prefetch on APU doesn't improve performance. If all it deteriotes. However, functionality has to be supported.

v2: Use apu_prefer_gtt as this issue doesn't apply to APUs with carveout VRAM

v3: Simplify by setting the flag for all ASICs as it doesn't affect dGPU

v4: Remove v2 and v3 changes. Force update_mapping when range is split at a size that is not aligned to prange granularity

(cherry picked from commit 076470b9f6f8d9c7c8ca73a9f054942a686f9ba7)

PATCH 31/60 HID: lenovo: fixup Lenovo Yoga Slim 7x Keyboard rdesc

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Lauri Tirkkonen <[email protected]>

[ Upstream commit a45f15808fb753a14c6041fd1e5bef5d552bd2e3 ]

The keyboard of this device has the following in its report description for Usage (Keyboard) in Collection (Application):

	# 0x15, 0x00,                    //  Logical Minimum (0)                52
	# 0x25, 0x65,                    //  Logical Maximum (101)              54
	# 0x05, 0x07,                    //  Usage Page (Keyboard)              56
	# 0x19, 0x00,                    //  Usage Minimum (0)                  58
	# 0x29, 0xdd,                    //  Usage Maximum (221)                60
	# 0x81, 0x00,                    //  Input (Data,Arr,Abs)               62

Since the Usage Min/Max range exceeds the Logical Min/Max range, keypresses outside the Logical range are not recognized. This includes, for example, the Japanese language keyboard variant's keys for |, _ and \.

Fixup the report description to make the Logical range match the Usage range, fixing the interpretation of keypresses above 101 on this device.

PATCH 32/60 bfs: Reconstruct file type when loading from disk

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Tetsuo Handa <[email protected]>

[ Upstream commit 34ab4c75588c07cca12884f2bf6b0347c7a13872 ]

syzbot is reporting that S_IFMT bits of inode->i_mode can become bogus when the S_IFMT bits of the 32bits "mode" field loaded from disk are corrupted or when the 32bits "attributes" field loaded from disk are corrupted.

A documentation says that BFS uses only lower 9 bits of the "mode" field. But I can't find an explicit explanation that the unused upper 23 bits (especially, the S_IFMT bits) are initialized with 0.

Therefore, ignore the S_IFMT bits of the "mode" field loaded from disk. Also, verify that the value of the "attributes" field loaded from disk is either BFS_VREG or BFS_VDIR (because BFS supports only regular files and the root directory).

PATCH 34/60 platform/x86/amd/pmc: Add support for Van Gogh SoC

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Antheas Kapenekakis <[email protected]>

[ Upstream commit db4a3f0fbedb0398f77b9047e8b8bb2b49f355bb ]

The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix suspend.

Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver to crash while trying to resume afterwards due to a power hang.

PATCH 36/60 nvme: fix admin request_queue lifetime

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Keith Busch <[email protected]>

[ Upstream commit 03b3bcd319b3ab5182bc9aaa0421351572c78ac0 ]

The namespaces can access the controller's admin request_queue, and stale references on the namespaces may exist after tearing down the controller. Ensure the admin request_queue is active by moving the controller's 'put' to after all controller references have been released to ensure no one is can access the request_queue. This fixes a reported use-after-free bug:

PATCH 37/60 pinctrl: qcom: msm: Fix deadlock in pinmux configuration

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Praveen Talari <[email protected]>

[ Upstream commit 1c2e70397b4125022dba80f6111271a37fb36bae ]

Replace disable_irq() with disable_irq_nosync() in msm_pinmux_set_mux() to prevent deadlock when wakeup IRQ is triggered on the same GPIO being reconfigured.

The issue occurs when a wakeup IRQ is triggered on a GPIO and the IRQ handler attempts to reconfigure the same GPIO's pinmux. In this scenario, msm_pinmux_set_mux() calls disable_irq() which waits for the currently running IRQ handler to complete, creating a circular dependency that results in deadlock.

Using disable_irq_nosync() avoids waiting for the IRQ handler to complete, preventing the deadlock condition while still properly disabling the interrupt during pinmux reconfiguration.

PATCH 38/60 platform/x86: acer-wmi: Ignore backlight event

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Armin Wolf <[email protected]>

[ Upstream commit 444a9256f8d106e08a6bc2dc8ef28a8699e4b3ba ]

On the Acer Nitro AN515-58, the event 4 - 0 is send by the ACPI firmware when the backlight up/down keys are pressed. Ignore this event to avoid spamming the kernel log with error messages, as the acpi-video driver already handles brightness up/down events.

atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.

So, add the spurious_8042 quirk for it. It does not have a keyboard, so this does not result in any functional loss.

PATCH 44/60 sched_ext: Fix possible deadlock in the deferred_irq_workfn()

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Zqiang <[email protected]>

[ Upstream commit a257e974210320ede524f340ffe16bf4bf0dda1e ]

For PREEMPT_RT=y kernels, the deferred_irq_workfn() is executed in the per-cpu irq_work/* task context and not disable-irq, if the rq returned by container_of() is current CPU's rq, the following scenarios may occur:

lock(&rq->__lock);
<Interrupt>
lock(&rq->__lock);

This commit use IRQ_WORK_INIT_HARD() to replace init_irq_work() to initialize rq->scx.deferred_irq_work, make the deferred_irq_workfn() is always invoked in hard-irq context.

The ELECOM M-XT3URBK trackball has an additional device ID (0x018F), which shares the same report descriptor as the existing device (0x00FB). However, the driver does not currently recognize this new ID, resulting in only five buttons being functional.

PATCH 47/60 sched_ext: Use IRQ_WORK_INIT_HARD() to initialize rq->scx.kick_cpus_irq_work

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

From: Zqiang <[email protected]>

[ Upstream commit 36c6f3c03d104faf1aa90922f2310549c175420f ]

For PREEMPT_RT kernels, the kick_cpus_irq_workfn() be invoked in the per-cpu irq_work/* task context and there is no rcu-read critical section to protect. this commit therefore use IRQ_WORK_INIT_HARD() to initialize the per-cpu rq->scx.kick_cpus_irq_work in the init_sched_ext_class().

PATCH 48/60 LoongArch: Mask all interrupts during kexec/kdump

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Huacai Chen <[email protected]>

[ Upstream commit 863a320dc6fd7c855f47da4bb82a8de2d9102ea2 ]

If the default state of the interrupt controllers in the first kernel don't mask any interrupts, it may cause the second kernel to potentially receive interrupts (which were previously allocated by the first kernel) immediately after a CPU becomes online during its boot process. These interrupts cannot be properly routed, leading to bad IRQ issues.

This patch calls machine_kexec_mask_interrupts() to mask all interrupts during the kexec/kdump process.

PATCH 49/60 samples: work around glibc redefining some of our defines wrong

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Linus Torvalds <[email protected]>

[ Upstream commit a48f822908982353c3256e35a089e9e7d0d61580 ]

Apparently as of version 2.42, glibc headers define AT_RENAME_NOREPLACE and some of the other flags for renameat2() and friends in <stdio.h>.

Which would all be fine, except for inexplicable reasons glibc decided to define them _differently_ from the kernel definitions, which then makes some of our sample code that includes both kernel headers and user space headers unhappy, because the compiler will (correctly) complain about redefining things.

Now, mixing kernel headers and user space headers is always a somewhat iffy proposition due to namespacing issues, but it's kind of inevitable in our sample and selftest code. And this is just glibc being stupid.

Those defines come from the kernel, glibc is exposing the kernel interfaces, and glibc shouldn't make up some random new expressions for these values.

It's not like glibc headers changed the actual result values, but they arbitrarily just decided to use a different expression to describe those values. The kernel just does

    #define AT_RENAME_NOREPLACE  0x0001

while glibc does

    # define RENAME_NOREPLACE (1 << 0)
    # define AT_RENAME_NOREPLACE RENAME_NOREPLACE

instead. Same value in the end, but very different macro definition.

For absolutely no reason.

This has since been fixed in the glibc development tree, so eventually we'll end up with the canonical expressions and no clashes. But in the meantime the broken headers are in the glibc-2.42 release and have made it out into distributions.

Do a minimal work-around to make the samples build cleanly by just undefining the affected macros in between the user space header include and the kernel header includes.

PATCH 50/60 platform/x86: hp-wmi: Add Omen 16-wf1xxx fan support

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Krishna Chomal <[email protected]>

[ Upstream commit fb146a38cb119c8d69633851c7a2ce2c8d34861a ]

The newer HP Omen laptops, such as Omen 16-wf1xxx, use the same WMI-based thermal profile interface as Victus 16-r1000 and 16-s1000 models.

Add the DMI board name "8C78" to the victus_s_thermal_profile_boards list to enable proper fan and thermal mode control.

Tested on: HP Omen 16-wf1xxx (board 8C78)
Result:
* Fan RPMs are readable
* echo 0 | sudo tee /sys/devices/platform/hp-wmi/hwmon/*/pwm1_enable allows the fans to run on max RPM.

PATCH 54/60 iio: adc: ad4080: fix chip identification

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Antoniu Miclaus <[email protected]>

commit b66cddc8be7278fd14650ff9182f3794397f8b31 upstream.

Fix AD4080 chip identification by using the correct 16-bit product ID (0x0050) instead of GENMASK(2, 0). Update the chip reading logic to use regmap_bulk_read to read both PRODUCT_ID_L and PRODUCT_ID_H registers and combine them into a 16-bit value.

The original implementation was incorrectly reading only 3 bits, which would not correctly identify the AD4080 chip.

Fixes 6b31ba1811b6 ("iio: adc: ad4080: add driver support")

PATCH 55/60 comedi: c6xdigio: Fix invalid PNP driver unregistration

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ian Abbott <[email protected]>

commit 72262330f7b3ad2130e800cecf02adcce3c32c77 upstream.

The Comedi low-level driver "c6xdigio" seems to be for a parallel port connected device. When the Comedi core calls the driver's Comedi "attach" handler c6xdigio_attach() to configure a Comedi to use this driver, it tries to enable the parallel port PNP resources by registering a PNP driver with pnp_register_driver(), but ignores the return value. (The struct pnp_driver it uses has only the name and id_table members filled in.) The driver's Comedi "detach" handler c6xdigio_detach() unconditionally unregisters the PNP driver with pnp_unregister_driver().

It is possible for c6xdigio_attach() to return an error before it calls pnp_register_driver() and it is possible for the call to pnp_register_driver() to return an error (that is ignored). In both cases, the driver should not be calling pnp_unregister_driver() as it does in c6xdigio_detach(). (Note that c6xdigio_detach() will be called by the Comedi core if c6xdigio_attach() returns an error, or if the Comedi core decides to detach the Comedi device from the driver for some other reason.)

The unconditional call to pnp_unregister_driver() without a previous successful call to pnp_register_driver() will cause driver_unregister() to issue a warning "Unexpected driver unregister!". This was detected by Syzbot [1].

Also, the PNP driver registration and unregistration should be done at module init and exit time, respectively, not when attaching or detaching Comedi devices to the driver. (There might be more than one Comedi device being attached to the driver, although that is unlikely.)

Change the driver to do the PNP driver registration at module init time, and the unregistration at module exit time. Since c6xdigio_detach() now only calls comedi_legacy_detach(), remove the function and change the Comedi driver "detach" handler to comedi_legacy_detach.

PATCH 56/60 comedi: multiq3: sanitize config options in multiq3_attach()

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nikita Zhandarovich <[email protected]>

commit f24c6e3a39fa355dabfb684c9ca82db579534e72 upstream.

Syzbot identified an issue [1] in multiq3_attach() that induces a task timeout due to open() or COMEDI_DEVCONFIG ioctl operations, specifically, in the case of multiq3 driver.

This problem arose when syzkaller managed to craft weird configuration options used to specify the number of channels in encoder subdevice. If a particularly great number is passed to s->n_chan in multiq3_attach() via it->options[2], then multiple calls to multiq3_encoder_reset() at the end of driver-specific attach() method will be running for minutes, thus blocking tasks and affected devices as well.

While this issue is most likely not too dangerous for real-life devices, it still makes sense to sanitize configuration inputs. Enable a sensible limit on the number of encoder chips (4 chips max, each with 2 channels) to stop this behaviour from manifesting.

[1] Syzbot crash:

PATCH 57/60 comedi: check devices attached status in compat ioctls

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nikita Zhandarovich <[email protected]>

commit 0de7d9cd07a2671fa6089173bccc0b2afe6b93ee upstream.

Syzbot identified an issue [1] that crashes kernel, seemingly due to unexistent callback dev->get_valid_routes(). By all means, this should not occur as said callback must always be set to get_zero_valid_routes() in __comedi_device_postconfig().

As the crash seems to appear exclusively in i386 kernels, at least, judging from [1] reports, the blame lies with compat versions of standard IOCTL handlers. Several of them are modified and do not use comedi_unlocked_ioctl(). While functionality of these ioctls essentially copy their original versions, they do not have required sanity check for device's attached status. This, in turn, leads to a possibility of calling select IOCTLs on a device that has not been properly setup, even via COMEDI_DEVCONFIG.

Doing so on unconfigured devices means that several crucial steps are missed, for instance, specifying dev->get_valid_routes() callback.

Fix this somewhat crudely by ensuring device's attached status before performing any ioctls, improving logic consistency between modern and compat functions.

[1] Syzbot report:

PATCH 58/60 staging: rtl8723bs: fix out-of-bounds read in rtw_get_ie() parser

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Navaneeth K <[email protected]>

commit 154828bf9559b9c8421fc2f0d7f7f76b3683aaed upstream.

The Information Element (IE) parser rtw_get_ie() trusted the length byte of each IE without validating that the IE body (len bytes after the 2-byte header) fits inside the remaining frame buffer. A malformed frame can advertise an IE length larger than the available data, causing the parser to increment its pointer beyond the buffer end. This results in out-of-bounds reads or, depending on the pattern, an infinite loop.

Fix by validating that (offset + 2 + len) does not exceed the limit before accepting the IE or advancing to the next element.

This prevents OOB reads and ensures the parser terminates safely on malformed frames.

PATCH 59/60 staging: rtl8723bs: fix stack buffer overflow in OnAssocReq IE parsing

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Navaneeth K <[email protected]>

commit 6ef0e1c10455927867cac8f0ed6b49f328f8cf95 upstream.

The Supported Rates IE length from an incoming Association Request frame was used directly as the memcpy() length when copying into a fixed-size 16-byte stack buffer (supportRate). A malicious station can advertise an IE length larger than 16 bytes, causing a stack buffer overflow.

Clamp ie_len to the buffer size before copying the Supported Rates IE, and correct the bounds check when merging Extended Supported Rates to prevent a second potential overflow.

This prevents kernel stack corruption triggered by malformed association requests.

PATCH 60/60 staging: rtl8723bs: fix out-of-bounds read in OnBeacon ESR IE parsing

In reply to Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Navaneeth K <[email protected]>

commit 502ddcc405b69fa92e0add6c1714d654504f6fd7 upstream.

The Extended Supported Rates (ESR) IE handling in OnBeacon accessed *(p + 1 + ielen) and *(p + 2 + ielen) without verifying that these offsets lie within the received frame buffer. A malformed beacon with an ESR IE positioned at the end of the buffer could cause an out-of-bounds read, potentially triggering a kernel panic.

Add a boundary check to ensure that the ESR IE body and the subsequent bytes are within the limits of the frame before attempting to access them.

This prevents OOB reads caused by malformed beacon frames.

Thnaks for the tutorial :)
1. should i start with the bad commit first ?

You start by marking one good (past) commit and one bad commit. It doesn't matter what order.

You have at least one "bad" commit you know of: 4112049d7836ad4233321c3d2b6853db1627c49c

This is the 6.12.62-rc1 commit that you reported had the error.

So, in your kernel worktree:

git bisect start
git bisect bad 4112049d7836ad4233321c3d2b6853db1627c49c

Now we need to tell git bisect the most recent "good" commit we know of (where the error didn't occur).

If you already know the commit or tag of a previous version where you did not get the error, mark that as good. If not, pick a previous release, check it out, and go to step 5.

Quoted 1 line

2. how to move forward or backward in commits ?

git bisect will do that for you as soon as you mark a good and bad commit. If you want to manually test a specific commit, just git checkout <ref> as usual, and continue at step 5 in the instructions I gave you.

Quoted 2 lines

3. what is the point in re-compiling the kernel if it cannot narrow down and test news lines of code

We're narrowing down the error to a specific kernel commit. Once we know which specific commit introduced the error, we can look at the lines changed and try to understand why. We need your help to find that commit, because it's happening on your system.

Please do read git help bisect (man 1 git-bisect). It explains all this better than I can.

Thanks for testing and good luck!

HTH.

Cheers,

Brett

Thnaks for the tutorial :)
1. should i start with the bad commit first ?

You start by marking one good (past) commit and one bad commit. It doesn't matter what order.

You have at least one "bad" commit you know of: 4112049d7836ad4233321c3d2b6853db1627c49c

This is the 6.12.62-rc1 commit that you reported had the error.

So, in your kernel worktree:

git bisect start
git bisect bad 4112049d7836ad4233321c3d2b6853db1627c49c

Now we need to tell git bisect the most recent "good" commit we know of (where the error didn't occur).

If you already know the commit or tag of a previous version where you did not get the error, mark that as good. If not, pick a previous release, check it out, and go to step 5.

Quoted 1 line

2. how to move forward or backward in commits ?

git bisect will do that for you as soon as you mark a good and bad commit. If you want to manually test a specific commit, just git checkout <ref> as usual, and continue at step 5 in the instructions I gave you.

Quoted 2 lines

3. what is the point in re-compiling the kernel if it cannot narrow down and test news lines of code

We're narrowing down the error to a specific kernel commit. Once we know which specific commit introduced the error, we can look at the lines changed and try to understand why. We need your help to find that commit, because it's happening on your system.

Quoted 8 lines

Please do read git help bisect (man 1 git-bisect). It explains all this better than I can.

Thanks for testing and good luck!

Brett

Now i have a much clearer vision. Thanks a ton !

Is ths new? if so, can you bisect?

this is new related. Previous stable release err and warn disappeared (i think i changed .config)

can you give me a step by step tutorial for git bisect

1) cd to wherever you have your kernel checked out

2) git bisect start

3) if you're already on a known-bad commit, then mark it as such:

git bisect bad

4) Mark the last known good commit as such:

git bisect good <commit / tag>

git bisect will choose a commit to test.

5) Build, install and boot your kernel as you usually do

6) Run whatever test you need to determine if the booted kernel is good or bad (check dmesg in this case)

7) Mark the commit as good or bad. Git will choose another commit for you.

8) Goto 5.

git help bisect will give you more information.

At the end of the process git will tell you the first bad commit found. You can dump the bisection log with:

git bisect log

which you can reply here with.
