[PATCH v2] Input: cyttsp5 - fix power control issue on wakeup

by Hugo Villeneuve

From: Mikael Gonella-Bolduc <mgonellabolduc(a)dimonoff.com> The power control function ignores the "on" argument when setting the report ID, and thus is always sending HID_POWER_SLEEP. This causes a problem when trying to wakeup. Fix by sending the state variable, which contains the proper HID_POWER_ON or HID_POWER_SLEEP based on the "on" argument. Fixes: 3c98b8dbdced ("Input: cyttsp5 - implement proper sleep and wakeup procedures") Cc: stable(a)vger.kernel.org Signed-off-by: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Signed-off-by: Mikael Gonella-Bolduc <mgonellabolduc(a)dimonoff.com> --- Changes for v2: - Add Mikael SOB tag drivers/input/touchscreen/cyttsp5.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/input/touchscreen/cyttsp5.c b/drivers/input/touchscreen/cyttsp5.c index eafe5a9b89648..86edcacb4ab3e 100644 --- a/drivers/input/touchscreen/cyttsp5.c +++ b/drivers/input/touchscreen/cyttsp5.c @@ -580,7 +580,7 @@ static int cyttsp5_power_control(struct cyttsp5 *ts, bool on) int rc; SET_CMD_REPORT_TYPE(cmd[0], 0); - SET_CMD_REPORT_ID(cmd[0], HID_POWER_SLEEP); + SET_CMD_REPORT_ID(cmd[0], state); SET_CMD_OPCODE(cmd[1], HID_CMD_SET_POWER); rc = cyttsp5_write(ts, HID_COMMAND_REG, cmd, sizeof(cmd)); base-commit: 7adf8b1afc14832de099f9e178f08f91dc0dd6d0 -- 2.39.5

Only reason to disable interrupts during bus resume would be to prevent the interrupt handler from interfering with the resume process of USB 2 ports. Host initiated resume of USB 2 ports is done in two stages. The xhci driver first transitions the port from 'U3' to 'Resume' state, then wait in Resume for 20ms, and finally moves port to U0 state. xhci driver can't prevent interrupts by keeping the xhci spinlock due to this 20ms sleep. Limit interrupt disabling to the USB 2 port resume case only. resuming USB 2 ports in bus resume is only done in special cases where USB 2 ports had to be forced to suspend during bus suspend. The current way of preventing interrupts by clearing the 'Interrupt Enable' (INTE) bit in USBCMD register won't prevent the Interrupter registers 'Interrupt Pending' (IP), 'Event Handler Busy' (EHB) and USBSTS register Event Interrupt (EINT) bits from being set. New interrupts can't be issued before those bits are properly clered. Disable interrupts by clearing the interrupter register 'Interrupt Enable' (IE) bit instead. This way IP, EHB and INTE won't be set before IE is enabled again and a new interrupt is triggered.

GCC 15 and stable kernels

by Chris Clayton

Hi Greg, I've built the four stable kernels that were released on 25 April. I found that to successfully build with GCC-15, each of them required backports of one or both of two upstream commits. Those commits are: Title Commit Author nonstring 9d7a0577c9db35c4cc52db90bc415ea248446472 Linus gnu11 b3bee1e7c3f2b1b77182302c7b2131c804175870 Alexey Dobriyan 6.14.4 and 6.12.25 required only nonstring. 6.6.87 required only gnu11, 6.1.35 required both. Additionally, chasing down why my new Bluetooth mouse doesn't work, I also had cause to build 5.15.180 and found that it needed gnull. I have TO dash out now, but I could send you a zip archive of the patches later today, if that would help. Chris

Re: FW: Wireless speed regression issue with >6.12.12/6.13.x + firmware update for mediatek MT7925

by Mingyen Hsieh (謝明諺)

Hi, Thanks for reporting this issue. We will conduct testing again. And it is already known that the patch added in 6.12.13 does have some issues, but we have also submitted new patches to fix. Currently, these patches are in the maintainer’s tree. It should soon be included in 6.14 and then ported Back to 6.12.x and 6.13.x. Perhaps you can test the driver from here: https://github.com/nbd168/wireless and apply this patch: https://patchwork.kernel.org/project/linux-wireless/patch/20250317011724.33… Thanks Best Regards, Yen.

[PATCH 6.6.y] x86/pvh: Call C code via the kernel virtual mapping

by Jason Andryuk

From: Ard Biesheuvel <ardb(a)kernel.org> [ Upstream commit e8fbc0d9cab6c1ee6403f42c0991b0c1d5dbc092 ] Calling C code via a different mapping than it was linked at is problematic, because the compiler assumes that RIP-relative and absolute symbol references are interchangeable. GCC in particular may use RIP-relative per-CPU variable references even when not using -fpic. So call xen_prepare_pvh() via its kernel virtual mapping on x86_64, so that those RIP-relative references produce the correct values. This matches the pre-existing behavior for i386, which also invokes xen_prepare_pvh() via the kernel virtual mapping before invoking startup_32 with paging disabled again.

This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

[linux-6.6.y bugreport] riscv: kprobe crash as some patchs lost

by Kai Zhang

In most recent linux-6.6.y tree, `arch/riscv/kernel/probes/kprobes.c::arch_prepare_ss_slot` still has the obsolete code: u32 insn = __BUG_INSN_32; unsigned long offset = GET_INSN_LENGTH(p->opcode); p->ainsn.api.restore = (unsigned long)p->addr + offset; patch_text_nosync(p->ainsn.api.insn, &p->opcode, 1); patch_text_nosync((void *)p->ainsn.api.insn + offset, &insn, 1); The last two 1s are wrong size of written instructions , which would lead to kernel crash, like `insmod kprobe_example.ko` gives: [ 509.812815][ T2734] kprobe_init: Planted kprobe at 00000000c5c46130 [ 509.837606][ C5] handler_pre: <kernel_clone> p->addr = 0x00000000c5c46130, pc = 0xffffffff80032ee2, status = 0x200000120 [ 509.839315][ C5] Oops - illegal instruction [#1] I've tried two patchs from torvalds tree and it didn't crash again: 51781ce8f448 riscv: Pass patch_text() the length in bytes (rebased) 13134cc94914 riscv: kprobes: Fix incorrect address calculation Regards, laokz

When one process do a report zones and another process freezes the block device, the report zones side cannot allocate a tag because the freeze is already started. This can thus result in new block group creation to hang forever, blocking the write path. Thankfully, a new block group should be created on empty zones. So, reporting the zones is not necessary and we can set the write pointer = 0 and load the zone capacity from the block layer using bdev_zone_capacity() helper. ====================================================== WARNING: possible circular locking dependency detected 6.14.0-rc1 #252 Not tainted ------------------------------------------------------ modprobe/1110 is trying to acquire lock: ffff888100ac83e0 ((work_completion)(&(&wb->dwork)->work)){+.+.}-{0:0}, at: __flush_work+0x38f/0xb60 but task is already holding lock: ffff8881205b6f20 (&q->q_usage_counter(queue)#16){++++}-{0:0}, at: sd_remove+0x85/0x130 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (&q->q_usage_counter(queue)#16){++++}-{0:0}: blk_queue_enter+0x3d9/0x500 blk_mq_alloc_request+0x47d/0x8e0 scsi_execute_cmd+0x14f/0xb80 sd_zbc_do_report_zones+0x1c1/0x470 sd_zbc_report_zones+0x362/0xd60 blkdev_report_zones+0x1b1/0x2e0 btrfs_get_dev_zones+0x215/0x7e0 [btrfs] btrfs_load_block_group_zone_info+0x6d2/0x2c10 [btrfs] btrfs_make_block_group+0x36b/0x870 [btrfs] btrfs_create_chunk+0x147d/0x2320 [btrfs] btrfs_chunk_alloc+0x2ce/0xcf0 [btrfs] start_transaction+0xce6/0x1620 [btrfs] btrfs_uuid_scan_kthread+0x4ee/0x5b0 [btrfs] kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #2 (&fs_info->dev_replace.rwsem){++++}-{4:4}: down_read+0x9b/0x470 btrfs_map_block+0x2ce/0x2ce0 [btrfs] btrfs_submit_chunk+0x2d4/0x16c0 [btrfs] btrfs_submit_bbio+0x16/0x30 [btrfs] btree_write_cache_pages+0xb5a/0xf90 [btrfs] do_writepages+0x17f/0x7b0 __writeback_single_inode+0x114/0xb00 writeback_sb_inodes+0x52b/0xe00 wb_writeback+0x1a7/0x800 wb_workfn+0x12a/0xbd0 process_one_work+0x85a/0x1460 worker_thread+0x5e2/0xfc0 kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #1 (&fs_info->zoned_meta_io_lock){+.+.}-{4:4}: __mutex_lock+0x1aa/0x1360 btree_write_cache_pages+0x252/0xf90 [btrfs] do_writepages+0x17f/0x7b0 __writeback_single_inode+0x114/0xb00 writeback_sb_inodes+0x52b/0xe00 wb_writeback+0x1a7/0x800 wb_workfn+0x12a/0xbd0 process_one_work+0x85a/0x1460 worker_thread+0x5e2/0xfc0 kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #0 ((work_completion)(&(&wb->dwork)->work)){+.+.}-{0:0}: __lock_acquire+0x2f52/0x5ea0 lock_acquire+0x1b1/0x540 __flush_work+0x3ac/0xb60 wb_shutdown+0x15b/0x1f0 bdi_unregister+0x172/0x5b0 del_gendisk+0x841/0xa20 sd_remove+0x85/0x130 device_release_driver_internal+0x368/0x520 bus_remove_device+0x1f1/0x3f0 device_del+0x3bd/0x9c0 __scsi_remove_device+0x272/0x340 scsi_forget_host+0xf7/0x170 scsi_remove_host+0xd2/0x2a0 sdebug_driver_remove+0x52/0x2f0 [scsi_debug] device_release_driver_internal+0x368/0x520 bus_remove_device+0x1f1/0x3f0 device_del+0x3bd/0x9c0 device_unregister+0x13/0xa0 sdebug_do_remove_host+0x1fb/0x290 [scsi_debug] scsi_debug_exit+0x17/0x70 [scsi_debug] __do_sys_delete_module.isra.0+0x321/0x520 do_syscall_64+0x93/0x180 entry_SYSCALL_64_after_hwframe+0x76/0x7e other info that might help us debug this: Chain exists of: (work_completion)(&(&wb->dwork)->work) --> &fs_info->dev_replace.rwsem --> &q->q_usage_counter(queue)#16 Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&q->q_usage_counter(queue)#16); lock(&fs_info->dev_replace.rwsem); lock(&q->q_usage_counter(queue)#16); lock((work_completion)(&(&wb->dwork)->work)); *** DEADLOCK *** 5 locks held by modprobe/1110: #0: ffff88811f7bc108 (&dev->mutex){....}-{4:4}, at: device_release_driver_internal+0x8f/0x520 #1: ffff8881022ee0e0 (&shost->scan_mutex){+.+.}-{4:4}, at: scsi_remove_host+0x20/0x2a0 #2: ffff88811b4c4378 (&dev->mutex){....}-{4:4}, at: device_release_driver_internal+0x8f/0x520 #3: ffff8881205b6f20 (&q->q_usage_counter(queue)#16){++++}-{0:0}, at: sd_remove+0x85/0x130 #4: ffffffffa3284360 (rcu_read_lock){....}-{1:3}, at: __flush_work+0xda/0xb60 stack backtrace: CPU: 0 UID: 0 PID: 1110 Comm: modprobe Not tainted 6.14.0-rc1 #252 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x6a/0x90 print_circular_bug.cold+0x1e0/0x274 check_noncircular+0x306/0x3f0 ?

Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect failure, the associated page must be released explicitly if it was previously retained via get_page(). Failing to do so may result in a memory leak, as the pages reference count is not decremented.

stable request: eaaff9b6702e ("netfilter: fib: avoid lookup if socket is available")

by Florian Westphal

Hi Greg, hi Sasha, Could you please queue up eaaff9b6702e ("netfilter: fib: avoid lookup if socket is available") for 6.14 and 6.12? Unfortunately I did not realize that the missing handling of 'input' is not just a missing optimization but an actual bug fix, else I would have split this patch in two. The bug exists since 5.19, but its not a regression ('never worked'). Given noone noticed/reported this until this week (https://lore.kernel.org/netfilter/20250422114352.GA2092@breakpoint.cc/), we think it makes sense to only apply this to the two most recent trees and keep the rest as-is, users of those trees evidently don't use the b0rken configuration or they would have complained long ago. The commit cherry-picks cleanly to both. If you disagree let me know, I could also make a stable-only patch that only contains the bug fix part of the mentioned commit. Thanks!

Stable request: net: stmmac: resume rx clocking

by Jon Hunter

Hi Greg, Sasha, Updates to the stmmac networking driver in Linux v6.14 exposed some issues with resuming the driver on platforms such as the Tegra186 Jetson TX2 board. This is why the suspend test has been failing on this platform for the linux-6.14.y updates ... Test failures: tegra186-p2771-0000: pm-system-suspend.sh Russell has provided some fixes for this that are now in the mainline and so I would like to integrate the following changes to linux-6.14.y ... f732549eb303 net: stmmac: simplify phylink_suspend() and phylink_resume() calls 367f1854d442 net: phylink: add phylink_prepare_resume() ef43e5132895 net: stmmac: address non-LPI resume failures properly 366aeeba7908 net: stmmac: socfpga: remove phy_resume() call ddf4bd3f7384 net: phylink: add functions to block/unblock rx clock stop dd557266cf5f net: stmmac: block PHY RXC clock-stop I had a quick look to see if we can backport to linux-6.12.y but looks like we need more commits and so for now just target linux-6.14.y. Jon

Please apply commit d81cadbe1642 to 6.12 stable tree

by Naveen N Rao

Please apply commit d81cadbe1642 ("KVM: SVM: Disable AVIC on SNP-enabled system without HvInUseWrAllowed feature") to the stable v6.12 tree. This patch prevents a kernel BUG by disabling AVIC on systems without suitable support for AVIC to work when SEV-SNP support is enabled in the host. Thanks, Naveen

Potential Linux Crash: possible deadlock in do_lock_mount in linux6.12.24(longterm maintenance)

by Jianzhou Zhao

Hello, I found a potential bug titled " possible deadlock in do_lock_mount " with modified syzkaller in the Linux6.12.24(longterm maintenance, last updated on April 20, 2025). (The latest version of 6.12 is 6.12-25 at present. However, after comparison, I found that there seems to be no fix for this bug in the latest version.) Unfortunately, I am unable to reproduce this bug. If you fix this issue, please add the following tag to the commit: Reported-by: Jianzhou Zhao <luckd0g(a)163.com>, xingwei lee <xrivendell7(a)gmail.com> The commit of the kernel is :

[PATCH v3 1/1] iommu: Allow attaching static domains in iommu_attach_device_pasid()

by Lu Baolu

The idxd driver attaches the default domain to a PASID of the device to perform kernel DMA using that PASID. The domain is attached to the device's PASID through iommu_attach_device_pasid(), which checks if the domain->owner matches the iommu_ops retrieved from the device. If they do not match, it returns a failure. if (ops != domain->owner || pasid == IOMMU_NO_PASID) return -EINVAL; The static identity domain implemented by the intel iommu driver doesn't specify the domain owner. Therefore, kernel DMA with PASID doesn't work for the idxd driver if the device translation mode is set to passthrough. Generally the owner field of static domains are not set because they are already part of iommu ops. Add a helper domain_iommu_ops_compatible() that checks if a domain is compatible with the device's iommu ops. This helper explicitly allows the static blocked and identity domains associated with the device's iommu_ops to be considered compatible.

[PATCH] LoongArch: Fix MAX_REG_OFFSET calculation

by Huacai Chen

Fix MAX_REG_OFFSET calculation, make it point to the last register in 'struct pt_regs' and not to the marker itself, which could allow regs_get_register() to return an invalid offset.

[PATCH] LoongArch: Move __arch_cpu_idle() to .cpuidle.text section

by Huacai Chen

Now arch_cpu_idle() is annotated with __cpuidle which means it is in the .cpuidle.text section, but __arch_cpu_idle() isn't. Thus, fix the missing .cpuidle.text section assignment for __arch_cpu_idle() in order to correct backtracing with nmi_backtrace(). The principle is similar to the commit 97c8580e85cf81c ("MIPS: Annotate cpu_wait implementations with __cpuidle") Cc: stable(a)vger.kernel.org Signed-off-by: Huacai Chen <chenhuacai(a)loongson.cn> --- arch/loongarch/kernel/genex.S | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/arch/loongarch/kernel/genex.S b/arch/loongarch/kernel/genex.S index 4f0912141781..733a7665e434 100644 --- a/arch/loongarch/kernel/genex.S +++ b/arch/loongarch/kernel/genex.S @@ -16,6 +16,7 @@ #include <asm/stackframe.h> #include <asm/thread_info.h> + .section .cpuidle.text, "ax" .align 5 SYM_FUNC_START(__arch_cpu_idle) /* start of idle interrupt region */ @@ -31,14 +32,16 @@ SYM_FUNC_START(__arch_cpu_idle) */ idle 0 /* end of idle interrupt region */ -1: jr ra +idle_exit: + jr ra SYM_FUNC_END(__arch_cpu_idle) + .previous SYM_CODE_START(handle_vint) UNWIND_HINT_UNDEFINED BACKUP_T0T1 SAVE_ALL - la_abs t1, 1b + la_abs t1, idle_exit LONG_L t0, sp, PT_ERA /* 3 instructions idle interrupt region */ ori t0, t0, 0b1100 -- 2.47.1

[PATCH rtw-next v2] wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 11ad:1723

by Mingcong Bai

RTL8723BE found on some ASUSTek laptops, such as F441U and X555UQ with subsystem ID 11ad:1723 are known to output large amounts of PCIe AER errors during and after boot up, causing heavy lags and at times lock-ups: pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5 pcieport 0000:00:1c.5: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID) pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 pcieport 0000:00:1c.5: [ 0] RxErr Disable ASPM on this combo as a quirk. This patch is a revision of a previous patch (linked below) which attempted to disable ASPM for RTL8723BE on all Intel Skylake and Kaby Lake PCIe bridges. I take a more conservative approach as all known reports point to ASUSTek laptops of these two generations with this particular wireless card. Please note, however, before the rtl8723be finishes probing, the AER errors remained. After the module finishes probing, all AER errors would indeed be eliminated, along with heavy lags, poor network throughput, and/or occasional lock-ups.

RE: Several questions for backporting fix for CVE-2024-50063 to linux-5.15/5.10

by Ren, Jianqi (Jacky) (CN)

Hello, We are evaluating CVE-2024-50063 for v5.15 and v5.10. But the context of v5.15 and v5.10 is behind current version quite a lot. It seems the suggested fix in https://www.cve.org/CVERecord?id=CVE-2024-50063, https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…, requires https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… to work. But it seems risky to port so many changes. Is it worth porting commit f45d5b6ce2e8 plus 28ead3eaabc1 to v5.15 and v5.10? Is there any mitigation for this CVE? Is there any reproducer and test case for this CVE so that we could validate the fix if we decide to port it?

[PATCH rc] iommu: Skip PASID validation for devices without PASID capability

by Tushar Dave

Generally PASID support requires ACS settings that usually create single device groups, but there are some niche cases where we can get multi-device groups and still have working PASID support. The primary issue is that PCI switches are not required to treat PASID tagged TLPs specially so appropriate ACS settings are required to route all TLPs to the host bridge if PASID is going to work properly. pci_enable_pasid() does check that each device that will use PASID has the proper ACS settings to achieve this routing. However, no-PASID devices can be combined with PASID capable devices within the same topology using non-uniform ACS settings. In this case the no-PASID devices may not have strict route to host ACS flags and end up being grouped with the PASID devices. This configuration fails to allow use of the PASID within the iommu core code which wrongly checks if the no-PASID device supports PASID. Fix this by ignoring no-PASID devices during the PASID validation. They will never issue a PASID TLP anyhow so they can be ignored.

[PATCH v4] arm64: dts: imx8mm-verdin: Link reg_usdhc2_vqmmc to usdhc2

by Wojciech Dubowik

Define vqmmc regulator-gpio for usdhc2 with vin-supply coming from LDO5. Without this definition LDO5 will be powered down, disabling SD card after bootup.

Hope to hear from you soon..

by MRS NORAH JANE

My Dear, I am pleased to find your email address via google search when i was searching for my lost childhood friend which I have not seen for the past 30 years, i have been searching for him on all social media platforms to no avail. Actually I was searching for him because of my health, which started since covid 19, 2020, covid 19 killed every member of my family, I am the only surviving member. I Survived the pandemic through the assistance of the CDC, But my life has never remained the same since ever then. my heart and lungs is Severely affected and damaged, my life is gradually fading away before me. I was searching for my childhood friend to be the beneficiary of my family estate and funds in the bank. When I saw your name there was something fascinating about it. Please can you grant me the opportunity to make you the beneficiary. I shall be awaiting your response for more details. Thanks Mrs Norah Jane

[PATCH 1/2] drm/dp: Correct Write_Status_Update_Request handling

by Wayne Lin

[Why] Notice few problems under I2C-write-over-Aux with Write_Status_Update_Request flag set cases: - I2C-write-over-Aux request with Write_Status_Update_Request flag set won't get sent upon the reply of I2C_ACK|AUX_ACK followed by “M” Value. Now just set the flag but won't send out - The I2C-over-Aux request command with Write_Status_Update_Request flag set is incorrect. Should be "SYNC->COM3:0 (= 0110)|0000-> 0000|0000-> 0|7-bit I2C address (the same as the last)-> STOP->". Address only transaction without length and data. - Upon I2C_DEFER|AUX_ACK Reply for I2C-read-over-Aux, soure should repeat the identical I2C-read-over-AUX transaction with the same LEN value. Not with Write_Status_Update_Request set. [How] Refer to DP v2.1: 2.11.7.1.5.3 & 2.11.7.1.5.4 - Clean aux msg buffer and size when constructing write status update request. - Send out Write_Status_Update_Request upon reply of I2C_ACK|AUX_ACK followed by “M” - Send Write_Status_Update_Request upon I2C_DEFER|AUX_ACK reply only when the request is I2C-write-over-Aux.

[PATCH v3] mips: Add -std= flag specified in KBUILD_CFLAGS to vdso CFLAGS

by Khem Raj

GCC 15 changed the default C standard dialect from gnu17 to gnu23, which should not have impacted the kernel because it explicitly requests the gnu11 standard in the main Makefile. However, mips/vdso code uses its own CFLAGS without a '-std=' value, which break with this dialect change because of the kernel's own definitions of bool, false, and true conflicting with the C23 reserved keywords. include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant 11 | false = 0, | ^~~~~ include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards include/linux/types.h:35:33: error: 'bool' cannot be defined via 'typedef' 35 | typedef _Bool bool; | ^~~~ include/linux/types.h:35:33: note: 'bool' is a keyword with '-std=c23' onwards Add -std as specified in KBUILD_CFLAGS to the decompressor and purgatory CFLAGS to eliminate these errors and make the C standard version of these areas match the rest of the kernel.

[PATCH 0/3 V2] Fix erroneous ioctl returns

by Dave Penkler

Recent tests with timeouts > INT_MAX produced random error returns with usbtmc_get_stb. This was caused by assigning the return value of wait_event_interruptible_timeout to an int which overflowed to negative values. Also return value on success was the remaining number of jiffies instead of 0. These patches fix all the cases where the return of wait_event_interruptible_timeout was assigned to an int and the case of the remaining jiffies return in usbtmc_get_stb. Patch 1: Fixes usbtmc_get_stb Patch 2: Fixes usbtmc488_ioctl_wait_srq Patch 3: Fixes usbtmc_generic_read Dave Penkler (3): usb: usbtmc: Fix erroneous get_stb ioctl error returns usb: usbtmc: Fix erroneous wait_srq ioctl return usb: usbtmc: Fix erroneous generic_read ioctl return drivers/usb/class/usbtmc.c | 53 ++++++++++++++++++++++---------------- 1 file changed, 31 insertions(+), 22 deletions(-) -- Changes V1 => V2 Add cc to stable line 2.49.0

Potential Linux Crash: possible deadlock in kernfs_unlink_sibling in linux6.12.24(longterm maintenance)

by Jianzhou Zhao

Hello, I found a potential bug titled " possible deadlock in kernfs_unlink_sibling " with modified syzkaller in the Linux6.12.24(longterm maintenance, last updated on April 20, 2025). (The latest version of 6.12 is 6.12-25 at present. However, after comparison, I found that there seems to be no fix for this bug in the latest version.) Unfortunately, I am unable to reproduce this bug. If you fix this issue, please add the following tag to the commit: Reported-by: Jianzhou Zhao <luckd0g(a)163.com>, xingwei lee <xrivendell7(a)gmail.com>,Penglei Jiang <superman.xpt(a)gmail.com> The

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 2ccd42b959aaf490333dbd3b9b102eaf295c036a Mon Sep 17 00:00:00 2001 From: David Hildenbrand <david(a)redhat.com> Date: Wed, 2 Apr 2025 22:36:21 +0200 Subject: [PATCH] s390/virtio_ccw: Don't allocate/assign airqs for non-existing queues If we finds a vq without a name in our input array in virtio_ccw_find_vqs(), we treat it as "non-existing" and set the vq pointer to NULL; we will not call virtio_ccw_setup_vq() to allocate/setup a vq. Consequently, we create only a queue if it actually exists (name != NULL) and assign an incremental queue index to each such existing queue. However, in virtio_ccw_register_adapter_ind()->get_airq_indicator() we will not ignore these "non-existing queues", but instead assign an airq indicator to them. Besides never releasing them in virtio_ccw_drop_indicators() (because there is no virtqueue), the bigger issue seems to be that there will be a disagreement between the device and the Linux guest about the airq indicator to be used for notifying a queue, because the indicator bit for adapter I/O interrupt is derived from the queue index. The virtio spec states under "Setting Up Two-Stage Queue Indicators": ... indicator contains the guest address of an area wherein the indicators for the devices are contained, starting at bit_nr, one bit per virtqueue of the device. And further in "Notification via Adapter I/O Interrupts": For notifying the driver of virtqueue buffers, the device sets the bit in the guest-provided indicator area at the corresponding offset. For example, QEMU uses in virtio_ccw_notify() the queue index (passed as "vector") to select the relevant indicator bit. If a queue does not exist, it does not have a corresponding indicator bit assigned, because it effectively doesn't have a queue index. Using a virtio-balloon-ccw device under QEMU with free-page-hinting disabled ("free-page-hint=off") but free-page-reporting enabled ("free-page-reporting=on") will result in free page reporting not working as expected: in the virtio_balloon driver, we'll be stuck forever in virtballoon_free_page_report()->wait_event(), because the waitqueue will not be woken up as the notification from the device is lost: it would use the wrong indicator bit. Free page reporting stops working and we get splats (when configured to detect hung wqs) like: INFO: task kworker/1:3:463 blocked for more than 61 seconds. Not tainted 6.14.0 #4 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. task:kworker/1:3 [...] Workqueue: events page_reporting_process Call Trace: [<000002f404e6dfb2>] __schedule+0x402/0x1640 [<000002f404e6f22e>] schedule+0x3e/0xe0 [<000002f3846a88fa>] virtballoon_free_page_report+0xaa/0x110 [virtio_balloon] [<000002f40435c8a4>] page_reporting_process+0x2e4/0x740 [<000002f403fd3ee2>] process_one_work+0x1c2/0x400 [<000002f403fd4b96>] worker_thread+0x296/0x420 [<000002f403fe10b4>] kthread+0x124/0x290 [<000002f403f4e0dc>] __ret_from_fork+0x3c/0x60 [<000002f404e77272>] ret_from_fork+0xa/0x38 There was recently a discussion [1] whether the "holes" should be treated differently again, effectively assigning also non-existing queues a queue index: that should also fix the issue, but requires other workarounds to not break existing setups. Let's fix it without affecting existing setups for now by properly ignoring the non-existing queues, so the indicator bits will match the queue indexes.

[PATCH stable 6.12 0/4] Fix xdp_devmap_attach failure in BPF selftests

by Shung-Hsi Yu

This patchset backport commit to fix BPF selftests failure in stable 6.12 since commit 972bafed67ca ("bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type()"), which is backport of upstream commit 6b3d638ca897. The fix needed is upstream commit c7f2188d68c1 ("selftests/bpf: Adjust data size to have ETH_HLEN"), which in turn depends on upstream commit d5fbcf46ee82 "selftests/bpf: make xdp_cpumap_attach keep redirect prog attached".

Consequently, we create only a queue if it actually exists (name != NULL) and assign an incremental queue index to each such existing queue. However, in virtio_ccw_register_adapter_ind()->get_airq_indicator() we will not ignore these "non-existing queues", but instead assign an airq indicator to them. Besides never releasing them in virtio_ccw_drop_indicators() (because there is no virtqueue), the bigger issue seems to be that there will be a disagreement between the device and the Linux guest about the airq indicator to be used for notifying a queue, because the indicator bit for adapter I/O interrupt is derived from the queue index. The virtio spec states under "Setting Up Two-Stage Queue Indicators": ... indicator contains the guest address of an area wherein the indicators for the devices are contained, starting at bit_nr, one bit per virtqueue of the device. And further in "Notification via Adapter I/O Interrupts": For notifying the driver of virtqueue buffers, the device sets the bit in the guest-provided indicator area at the corresponding offset. For example, QEMU uses in virtio_ccw_notify() the queue index (passed as "vector") to select the relevant indicator bit. If a queue does not exist, it does not have a corresponding indicator bit assigned, because it effectively doesn't have a queue index. Using a virtio-balloon-ccw device under QEMU with free-page-hinting disabled ("free-page-hint=off") but free-page-reporting enabled ("free-page-reporting=on") will result in free page reporting not working as expected: in the virtio_balloon driver, we'll be stuck forever in virtballoon_free_page_report()->wait_event(), because the waitqueue will not be woken up as the notification from the device is lost: it would use the wrong indicator bit. Free page reporting stops working and we get splats (when configured to detect hung wqs) like: INFO: task kworker/1:3:463 blocked for more than 61 seconds.

[PATCH stable 6.12 6.14 1/1] selftests/bpf: Mitigate sockmap_ktls disconnect_after_delete failure

by Shung-Hsi Yu

From: Ihor Solodrai <ihor.solodrai(a)linux.dev> commit 5071a1e606b30c0c11278d3c6620cd6a24724cf6 upstream. "sockmap_ktls disconnect_after_delete" test has been failing on BPF CI after recent merges from netdev: * https://github.com/kernel-patches/bpf/actions/runs/14458537639 * https://github.com/kernel-patches/bpf/actions/runs/14457178732 It happens because disconnect has been disabled for TLS [1], and it renders the test case invalid. Removing all the test code creates a conflict between bpf and bpf-next, so for now only remove the offending assert [2]. The test will be removed later on bpf-next.

[PATCH 5.10.y] perf/x86/intel/uncore: Fix the scale of IIO free running counters on SNR

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> [ Upstream commit 96a720db59ab330c8562b2437153faa45dac705f ] (The existing patch in queue-5.10 was wrong. queue-5.10/perf-x86-intel-uncore-fix-the-scale-of-iio-free-running-counters-on-snr.patch It's supposed to change the array snr_uncore_iio_freerunning_events[] rather than icx_uncore_iio_freerunning_events[]. Send the patch to replace the wrong one. With this fix the https://lore.kernel.org/stable/2025042139-protector-rickety-a72d@gregkh/ can be applied then.) There was a mistake in the SNR uncore spec. The counter increments for every 32 bytes of data sent from the IO agent to the SOC, not 4 bytes which was documented in the spec. The event list has been updated: "EventName": "UNC_IIO_BANDWIDTH_IN.PART0_FREERUN", "BriefDescription": "Free running counter that increments for every 32 bytes of data sent from the IO agent to the SOC", Update the scale of the IIO bandwidth in free running counters as well.

[PATCH 6.1.y] of: module: add buffer overflow check in of_modalias()

From: Sergey Shtylyov <s.shtylyov(a)omp.ru> [ Upstream commit cf7385cb26ac4f0ee6c7385960525ad534323252 ] In of_modalias(), if the buffer happens to be too small even for the 1st snprintf() call, the len parameter will become negative and str parameter (if not NULL initially) will point beyond the buffer's end. Add the buffer overflow check after the 1st snprintf() call and fix such check after the strlen() call (accounting for the terminating NUL char).

Consequently, we create only a queue if it actually exists (name != NULL) and assign an incremental queue index to each such existing queue. However, in virtio_ccw_register_adapter_ind()->get_airq_indicator() we will not ignore these "non-existing queues", but instead assign an airq indicator to them. Besides never releasing them in virtio_ccw_drop_indicators() (because there is no virtqueue), the bigger issue seems to be that there will be a disagreement between the device and the Linux guest about the airq indicator to be used for notifying a queue, because the indicator bit for adapter I/O interrupt is derived from the queue index. The virtio spec states under "Setting Up Two-Stage Queue Indicators": ... indicator contains the guest address of an area wherein the indicators for the devices are contained, starting at bit_nr, one bit per virtqueue of the device. And further in "Notification via Adapter I/O Interrupts": For notifying the driver of virtqueue buffers, the device sets the bit in the guest-provided indicator area at the corresponding offset. For example, QEMU uses in virtio_ccw_notify() the queue index (passed as "vector") to select the relevant indicator bit. If a queue does not exist, it does not have a corresponding indicator bit assigned, because it effectively doesn't have a queue index. Using a virtio-balloon-ccw device under QEMU with free-page-hinting disabled ("free-page-hint=off") but free-page-reporting enabled ("free-page-reporting=on") will result in free page reporting not working as expected: in the virtio_balloon driver, we'll be stuck forever in virtballoon_free_page_report()->wait_event(), because the waitqueue will not be woken up as the notification from the device is lost: it would use the wrong indicator bit.

[PATCH v2] usb: dwc3: Abort suspend on soft disconnect failure

by Kuen-Han Tsai

When dwc3_gadget_soft_disconnect() fails, dwc3_suspend_common() keeps going with the suspend, resulting in a period where the power domain is off, but the gadget driver remains connected. Within this time frame, invoking vbus_event_work() will cause an error as it attempts to access DWC3 registers for endpoint disabling after the power domain has been completely shut down. Abort the suspend sequence when dwc3_gadget_suspend() cannot halt the controller and proceeds with a soft connect.

[PATCH v3] KVM: SVM: forcibly leave SMM mode on vCPU reset

by Mikhail Lobanov

Previously, commit ed129ec9057f ("KVM: x86: forcibly leave nested mode on vCPU reset") addressed an issue where a triple fault occurring in nested mode could lead to use-after-free scenarios. However, the commit did not handle the analogous situation for System Management Mode (SMM). This omission results in triggering a WARN when a vCPU reset occurs while still in SMM mode, due to the check in kvm_vcpu_reset(). This situation was reprodused using Syzkaller by: 1) Creating a KVM VM and vCPU 2) Sending a KVM_SMI ioctl to explicitly enter SMM 3) Executing invalid instructions causing consecutive exceptions and eventually a triple fault The issue manifests as follows: WARNING: CPU: 0 PID: 25506 at arch/x86/kvm/x86.c:12112 kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Modules linked in: CPU: 0 PID: 25506 Comm: syz-executor.0 Not tainted 6.1.130-syzkaller-00157-g164fe5dde9b6 #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 RIP: 0010:kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Call Trace: <TASK> shutdown_interception+0x66/0xb0 arch/x86/kvm/svm/svm.c:2136 svm_invoke_exit_handler+0x110/0x530 arch/x86/kvm/svm/svm.c:3395 svm_handle_exit+0x424/0x920 arch/x86/kvm/svm/svm.c:3457 vcpu_enter_guest arch/x86/kvm/x86.c:10959 [inline] vcpu_run+0x2c43/0x5a90 arch/x86/kvm/x86.c:11062 kvm_arch_vcpu_ioctl_run+0x50f/0x1cf0 arch/x86/kvm/x86.c:11283 kvm_vcpu_ioctl+0x570/0xf00 arch/x86/kvm/../../../virt/kvm/kvm_main.c:4122 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x19a/0x210 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x35/0x80 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x6e/0xd8 Architecturally, hardware CPUs exit SMM upon receiving a triple fault as part of a hardware reset. To reflect this behavior and avoid triggering the WARN, this patch explicitly calls kvm_smm_changed(vcpu, false) in the SVM-specific shutdown_interception() handler prior to resetting the vCPU. The initial version of this patch attempted to address the issue by calling kvm_smm_changed() inside kvm_vcpu_reset(). However, this approach was not architecturally accurate, as INIT is blocked during SMM and SMM should not be exited implicitly during a generic vCPU reset. This version moves the fix into shutdown_interception() for SVM, where the triple fault is actually handled, and where exiting SMM explicitly is appropriate. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH 1/2] mm/userfaultfd: Fix uninitialized output field for -EAGAIN race

by Peter Xu

While discussing some userfaultfd relevant issues recently, Andrea noticed a potential ABI breakage with -EAGAIN on almost all userfaultfd ioctl()s. Quote from Andrea, explaining how -EAGAIN was processed, and how this should fix it (taking example of UFFDIO_COPY ioctl): The "mmap_changing" and "stale pmd" conditions are already reported as -EAGAIN written in the copy field, this does not change it. This change removes the subnormal case that left copy.copy uninitialized and required apps to explicitly set the copy field to get deterministic behavior (which is a requirement contrary to the documentation in both the manpage and source code). In turn there's no alteration to backwards compatibility as result of this change because userland will find the copy field consistently set to -EAGAIN, and not anymore sometime -EAGAIN and sometime uninitialized. Even then the change only can make a difference to non cooperative users of userfaultfd, so when UFFD_FEATURE_EVENT_* is enabled, which is not true for the vast majority of apps using userfaultfd or this unintended uninitialized field may have been noticed sooner. Meanwhile, since this bug existed for years, it also almost affects all ioctl()s that was introduced later. Besides UFFDIO_ZEROPAGE, these also get affected in the same way: - UFFDIO_CONTINUE - UFFDIO_POISON - UFFDIO_MOVE This patch should have fixed all of them.

[PATCH] usb: uhci-platform: Make the clock really optional

by Alexey Charkov

Device tree bindings state that the clock is optional for UHCI platform controllers, and some existing device trees don't provide those - such as those for VIA/WonderMedia devices. The driver however fails to probe now if no clock is provided, because devm_clk_get returns an error pointer in such case. Switch to devm_clk_get_optional instead, so that it could probe again on those platforms where no clocks are given.

[PATCH RESEND v3 0/3] Add ti,suppress-v1p8-ena

by Judith Mendez

Resend patch series to fix cc list There are MMC boot failures seen with V1P8_SIGNAL_ENA on Kingston eMMC and Microcenter/Patriot SD cards on Sitara K3 boards due to the HS200 initialization sequence involving V1P8_SIGNAL_ENA. Since V1P8_SIGNAL_ENA is optional for eMMC, do not set V1P8_SIGNAL_ENA by default for eMMC. For SD cards we shall parse DT for ti,suppress-v1p8-ena property to determine whether to suppress V1P8_SIGNAL_ENA. Add new ti,suppress-v1p8-ena to am62x, am62ax, and am62px SoC dtsi files since there is no internal LDO tied to sdhci1 interface so V1P8_SIGNAL_ENA only affects timing. This fix was previously merged in the kernel, but was reverted due to the "heuristics for enabling the quirk"[0]. This issue is adressed in this patch series by adding optional ti,suppress-v1p8-ena DT property which determines whether to apply the quirk for SD. Changes since v2: - Include patch 3/3 - Reword cover letter - Reword binding patch description - Add fixes/cc tags to driver patch - Reorder patches according to binding patch first - Resend to fix cc list in original v3 series Link to v2: https://lore.kernel.org/linux-mmc/20250417182652.3521104-1-jm@ti.com/ Link to v1: https://lore.kernel.org/linux-mmc/20250407222702.2199047-1-jm@ti.com/ [0] https://lore.kernel.org/linux-mmc/20250127-am654-mmc-regression-v2-1-9bb39f… Judith Mendez (3): dt-bindings: mmc: sdhci-am654: Add ti,suppress-v1p8-ena mmc: sdhci_am654: Add sdhci_am654_start_signal_voltage_switch arm64: dts: ti: k3-am62*: add ti,suppress-v1p8-ena .../devicetree/bindings/mmc/sdhci-am654.yaml | 5 +++ arch/arm64/boot/dts/ti/k3-am62-main.dtsi | 1 + arch/arm64/boot/dts/ti/k3-am62a-main.dtsi | 1 + .../dts/ti/k3-am62p-j722s-common-main.dtsi | 1 + drivers/mmc/host/sdhci_am654.c | 32 +++++++++++++++++++ 5 files changed, 40 insertions(+) base-commit: 1be38f81251f6d276713c259ecf4414f82f22c29 -- 2.49.0

[PATCH v2 1/4] firmware: arm_scmi: Ensure that the message-id supports fastchannel

[PATCH] ASoC: renesas: rz-ssi: Use NOIRQ_SYSTEM_SLEEP_PM_OPS()

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> In the latest kernel versions system crashes were noticed occasionally during suspend/resume. This occurs because the RZ SSI suspend trigger (called from snd_soc_suspend()) is executed after rz_ssi_pm_ops->suspend() and it accesses IP registers. After the rz_ssi_pm_ops->suspend() is executed the IP clocks are disabled and its reset line is asserted. Since snd_soc_suspend() is invoked through snd_soc_pm_ops->suspend(), snd_soc_pm_ops is associated with soc_driver (defined in sound/soc/soc-core.c), and there is no parent-child relationship between soc_driver and rz_ssi_driver the power management subsystem does not enforce a specific suspend/resume order between the RZ SSI platform driver and soc_driver. To ensure that the suspend/resume function of rz-ssi is executed after snd_soc_suspend(), use NOIRQ_SYSTEM_SLEEP_PM_OPS().

[PATCH] ASoC: meson: meson-card-utils: use of_property_present() for DT parsing

by Martin Blumenstingl

Commit c141ecc3cecd ("of: Warn when of_property_read_bool() is used on non-boolean properties") added a warning when trying to parse a property with a value (boolean properties are defined as: absent = false, present without any value = true). This causes a warning from meson-card-utils. meson-card-utils needs to know about the existence of the "audio-routing" and/or "audio-widgets" properties in order to properly parse them. Switch to of_property_present() in order to silence the following warning messages during boot: OF: /sound: Read of boolean property 'audio-routing' with a value. OF: /sound: Read of boolean property 'audio-widgets' with a value.

Typically HDMI to MIPI CSI-2 bridges have a pin to signal image data is being received. On the host side this is wired to a GPIO for polling or interrupts. This includes the Lontium HDMI to MIPI CSI-2 bridges lt6911uxe and lt6911uxc. The GPIO "hpd" is used already by other HDMI to CSI-2 bridges, use it here as well.

Linux 6.12.25

[PATCH v4 1/2] serial: sifive: lock port in startup()/shutdown() callbacks

by Ryo Takakura

startup()/shutdown() callbacks access SIFIVE_SERIAL_IE_OFFS. The register is also accessed from write() callback. If console were printing and startup()/shutdown() callback gets called, its access to the register could be overwritten. Add port->lock to startup()/shutdown() callbacks to make sure their access to SIFIVE_SERIAL_IE_OFFS is synchronized against write() callback.

[PATCH v2] media: ov2740: Move pm-runtime cleanup on probe-errors to proper place

by Hans de Goede

When v4l2_subdev_init_finalize() fails no changes have been made to the runtime-pm device state yet, so the probe_error_media_entity_cleanup rollback path should not touch the runtime-pm device state. Instead this should be done from the probe_error_v4l2_subdev_cleanup rollback path. Note the pm_runtime_xxx() calls are put above the v4l2_subdev_cleanup() call to have the reverse call order of probe().

[PATCH] wifi: rtw88: use ieee80211_purge_tx_queue() to purge TX skb

by Ladislav Michl

From: Ladislav Michl <ladis(a)triops.cz> corresponding upstream commit 3e5e4a801aaf4283390cc34959c6c48f910ca5ea When removing kernel modules driver uses skb_queue_purge() to purge TX skb, but not report tx status causing "Have pending ack frames!" warning. Use ieee80211_purge_tx_queue() to correct this.

[PATCH v4 1/2] staging: iio: frequency: ad9832: Use SLEEP bit instead of RESET to disable output

by Gabriel Shahrouzi

According to the AD9832 datasheet (Table 10, D12 description), setting the RESET bit forces the phase accumulator to zero, which corresponds to a full-scale DC output, rather than disabling the output signal. The correct way to disable the output and enter a low-power state is to set the AD9832_SLEEP bit (Table 10, D13 description), which powers down the internal DAC current sources and disables internal clocks.

So, the tests that are part of your (Intel) accel-config package are the only convenient way that I’ve found to do so. It is also convenient, there is a “make check” target in the top Makefile that will invoke both set of DMA tests, and some crypto (IAA) tests. I have been planning to give this to our QA group as a verification suite. Do you have an alternative to this? This should be the right test package. Let me talk to our QA people and see if there are any issues. We can resolve this off list. If there's any issues that end up pointing to the original bug, we can raise that then.

+ mm-userfaultfd-fix-uninitialized-output-field-for-eagain-race.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm/userfaultfd: fix uninitialized output field for -EAGAIN race has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-userfaultfd-fix-uninitialized-output-field-for-eagain-race.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Peter Xu <peterx(a)redhat.com> Subject: mm/userfaultfd: fix uninitialized output field for -EAGAIN race Date: Thu, 24 Apr 2025 17:57:28 -0400 While discussing some userfaultfd relevant issues recently, Andrea noticed a potential ABI breakage with -EAGAIN on almost all userfaultfd ioctl()s. Quote from Andrea, explaining how -EAGAIN was processed, and how this should fix it (taking example of UFFDIO_COPY ioctl): The "mmap_changing" and "stale pmd" conditions are already reported as -EAGAIN written in the copy field, this does not change it. This change removes the subnormal case that left copy.copy uninitialized and required apps to explicitly set the copy field to get deterministic behavior (which is a requirement contrary to the documentation in both the manpage and source code). In turn there's no alteration to backwards compatibility as result of this change because userland will find the copy field consistently set to -EAGAIN, and not anymore sometime -EAGAIN and sometime uninitialized. Even then the change only can make a difference to non cooperative users of userfaultfd, so when UFFD_FEATURE_EVENT_* is enabled, which is not true for the vast majority of apps using userfaultfd or this unintended uninitialized field may have been noticed sooner. Meanwhile, since this bug existed for years, it also almost affects all ioctl()s that was introduced later. Besides UFFDIO_ZEROPAGE, these also get affected in the same way: - UFFDIO_CONTINUE - UFFDIO_POISON - UFFDIO_MOVE This patch should have fixed all of them.

[PATCH stable] xdp: Reset bpf_redirect_info before running a xdp's BPF prog.

by Sebastian Andrzej Siewior

Ricardo reported a KASAN discovered use after free in v6.6-stable. The syzbot starts a BPF program via xdp_test_run_batch() which assigns ri->tgt_value via dev_hash_map_redirect() and the return code isn't XDP_REDIRECT it looks like nonsense. So the output in bpf_warn_invalid_xdp_action() appears once. Then the TUN driver runs another BPF program (on the same CPU) which returns XDP_REDIRECT without setting ri->tgt_value first. It invokes bpf_trace_printk() to print four characters and obtain the required return value. This is enough to get xdp_do_redirect() invoked which then accesses the pointer in tgt_value which might have been already deallocated. This problem does not affect upstream because since commit 401cb7dae8130 ("net: Reference bpf_redirect_info via task_struct on PREEMPT_RT.") the per-CPU variable is referenced via task's task_struct and exists on the stack during NAPI callback. Therefore it is cleared once before the first invocation and remains valid within the RCU section of the NAPI callback. Instead of performing the huge backport of the commit (plus its fix ups) here is an alternative version which only resets the variable in question prior invoking the BPF program.

Like I said, it got no messages booting up, all looked fine. But when running the actual test suite in the accel-config tarball specifically the iaa crypt tests, they failed and the dmesg was from vfio_pci_core failed to load with an unknown symbol. I'm not sure what the test consists of (haven't worked on this device for almost 2 years). But usually the device is either bound to the idxd driver or the vfio_pci driver. Not both. And if the idxd driver didn't emit any errors while loading, then the test failure may be something else... Another way to verify is to set CONFIG_IOMMU_DEFAULT_DMA_LAZY vs PASSTHROUGH. If the tests still fail then it's something else.

[alternative-merged] smaps-fix-crash-in-smaps_hugetlb_range-for-non-present-hugetlb-entries.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: smaps: fix crash in smaps_hugetlb_range for non-present hugetlb entries has been removed from the -mm tree. Its filename was smaps-fix-crash-in-smaps_hugetlb_range-for-non-present-hugetlb-entries.patch This patch was dropped because an alternative patch was or shall be merged ------------------------------------------------------ From: Ming Wang <wangming01(a)loongson.cn> Subject: smaps: fix crash in smaps_hugetlb_range for non-present hugetlb entries Date: Wed, 23 Apr 2025 09:03:59 +0800 When reading /proc/pid/smaps for a process that has mapped a hugetlbfs file with MAP_PRIVATE, the kernel might crash inside pfn_swap_entry_to_page. This occurs on LoongArch under specific conditions. The root cause involves several steps: 1. When the hugetlbfs file is mapped (MAP_PRIVATE), the initial PMD (or relevant level) entry is often populated by the kernel during mmap() with a non-present entry pointing to the architecture's invalid_pte_table On the affected LoongArch system, this address was observed to be 0x90000000031e4000. 2. The smaps walker (walk_hugetlb_range -> smaps_hugetlb_range) reads this entry. 3. The generic is_swap_pte() macro checks `!pte_present() && !pte_none()`. The entry (invalid_pte_table address) is not present. Crucially, the generic pte_none() check (`!(pte_val(pte) & ~_PAGE_GLOBAL)`) returns false because the invalid_pte_table address is non-zero. Therefore, is_swap_pte() incorrectly returns true. 4. The code enters the `else if (is_swap_pte(...))` block. 5. Inside this block, it checks `is_pfn_swap_entry()`. Due to a bit pattern coincidence in the invalid_pte_table address on LoongArch, the embedded generic `is_migration_entry()` check happens to return true (misinterpreting parts of the address as a migration type). 6. This leads to a call to pfn_swap_entry_to_page() with the bogus swap entry derived from the invalid table address. 7. pfn_swap_entry_to_page() extracts a meaningless PFN, finds an unrelated struct page, checks its lock status (unlocked), and hits the `BUG_ON(is_migration_entry(entry) && !PageLocked(p))` assertion. The original code's intent in the `else if` block seems aimed at handling potential migration entries, as indicated by the inner `is_pfn_swap_entry()` check. The issue arises because the outer `is_swap_pte()` check incorrectly includes the invalid table pointer case on LoongArch. This patch fixes the issue by changing the condition in smaps_hugetlb_range() from the broad `is_swap_pte()` to the specific `is_hugetlb_entry_migration()`. The `is_hugetlb_entry_migration()` helper function correctly handles this by first checking `huge_pte_none()`. Architectures like LoongArch can provide an override for `huge_pte_none()` that specifically recognizes the `invalid_pte_table` address as a "none" state for HugeTLB entries. This ensures `is_hugetlb_entry_migration()` returns false for the invalid entry, preventing the code from entering the faulty block. This change makes the code reflect the likely original intent (handling migration) more accurately and leverages architecture-specific helpers (`huge_pte_none`) to correctly interpret special PTE/PMD values in the HugeTLB context, fixing the crash on LoongArch without altering the generic is_swap_pte() behavior.

[PATCH] btrfs: adjust subpage bit start based on sectorsize

by Josef Bacik

When running machines with 64k page size and a 16k nodesize we started seeing tree log corruption in production. This turned out to be because we were not writing out dirty blocks sometimes, so this in fact affects all metadata writes. When writing out a subpage EB we scan the subpage bitmap for a dirty range. If the range isn't dirty we do bit_start++; to move onto the next bit. The problem is the bitmap is based on the number of sectors that an EB has. So in this case, we have a 64k pagesize, 16k nodesize, but a 4k sectorsize. This means our bitmap is 4 bits for every node. With a 64k page size we end up with 4 nodes per page. To make this easier this is how everything looks [0 16k 32k 48k ] logical address [0 4 8 12 ] radix tree offset [ 64k page ] folio [ 16k eb ][ 16k eb ][ 16k eb ][ 16k eb ] extent buffers [ | | | | | | | | | | | | | | | | ] bitmap Now we use all of our addressing based on fs_info->sectorsize_bits, so as you can see the above our 16k eb->start turns into radix entry 4. When we find a dirty range for our eb, we correctly do bit_start += sectors_per_node, because if we start at bit 0, the next bit for the next eb is 4, to correspond to eb->start 16k. However if our range is clean, we will do bit_start++, which will now put us offset from our radix tree entries. In our case, assume that the first time we check the bitmap the block is not dirty, we increment bit_start so now it == 1, and then we loop around and check again. This time it is dirty, and we go to find that start using the following equation start = folio_start + bit_start * fs_info->sectorsize; so in the case above, eb->start 0 is now dirty, and we calculate start as 0 + 1 * fs_info->sectorsize = 4096 4096 >> 12 = 1 Now we're looking up the radix tree for 1, and we won't find an eb. What's worse is now we're using bit_start == 1, so we do bit_start += sectors_per_node, which is now 5. If that eb is dirty we will run into the same thing, we will look at an offset that is not populated in the radix tree, and now we're skipping the writeout of dirty extent buffers. The best fix for this is to not use sectorsize_bits to address nodes, but that's a larger change. Since this is a fs corruption problem fix it simply by always using sectors_per_node to increment the start bit. cc: stable(a)vger.kernel.org Fixes: c4aec299fa8f ("btrfs: introduce submit_eb_subpage() to submit a subpage metadata page") Reviewed-by: Boris Burkov <boris(a)bur.io> Signed-off-by: Josef Bacik <josef(a)toxicpanda.com> --- - Further testing indicated that the page tagging theoretical race isn't getting hit in practice, so we're going to limit the "hotfix" to this specific patch, and then send subsequent patches to address the other issues we're hitting.

[PATCH v2] x86/sev: Fix SNP guest kdump hang/softlockup/panic

[PATCH] x86/sev: Fix making shared pages private during kdump

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> When the shared pages are being made private during kdump preparation there are additional checks to handle shared GHCB pages. These additional checks include handling the case of GHCB page being contained within a 2MB page. There is a bug in this additional check for GHCB page contained within a 2MB page which causes any shared page just below the per-cpu GHCB getting skipped from being transitioned back to private before kdump preparation which subsequently causes a 0x404 #VC exception when this shared page is accessed later while dumping guest memory during vmcore generation via kdump. Correct the detection and handling of GHCB pages contained within a 2MB page.

[PATCH net] gve: Add adminq lock for creating and destroying multiple queues

by Harshitha Ramamurthy

From: Ziwei Xiao <ziweixiao(a)google.com> The original adminq lock is only protecting the gve_adminq_execute_cmd which is aimed for sending out single adminq command. However, there are other callers of gve_adminq_kick_and_wait and gve_adminq_issue_cmd that need to take the mutex lock for mutual exclusion between them, which are creating and destroying rx/tx queues. Add the adminq lock for those unprotected callers. Also this patch cleans up the error handling code of gve_adminq_destroy_tx_queue.

[PATCH v2] mm, slab: clean up slab->obj_exts always

by Zhenhua Huang

When memory allocation profiling is disabled at runtime or due to an error, shutdown_mem_profiling() is called: slab->obj_exts which previously allocated remains. It won't be cleared by unaccount_slab() because of mem_alloc_profiling_enabled() not true. It's incorrect, slab->obj_exts should always be cleaned up in unaccount_slab() to avoid following error: [...]BUG: Bad page state in process... ..

Please apply commit 8983dc1b66c0 ("ALSA: hda/realtek: Fix built-in mic on another ASUS VivoBook model") to v6.1.y (and v6.6.y)

by Salvatore Bonaccorso

Hi As per subject, can you please apply commit 8983dc1b66c0 ("ALSA: hda/realtek: Fix built-in mic on another ASUS VivoBook model") to v6.1.y? The commit fixes 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"), which is in 6.14-rc1 *but* it got backported to other stable series as well: 6.1.129, 6.6.78, 6.12.14 and 6.13.3. While 8983dc1b66c0 got then backported down to 6.12.23, 6.13.11 and and 6.14.2 it was not backported further down, the reason is likely the commit does not apply cleanly due to context changes in the struct hda_quirk alc269_fixup_tbl (as some entries are missing in older series). For context see as well: https://lore.kernel.org/linux-sound/Z95s5T6OXFPjRnKf@eldamar.lan https://lore.kernel.org/linux-sound/Z_aq9kkdswrGZRUQ@eldamar.lan/ https://bugs.debian.org/1100928 Can you please apply it down for 6.1.y? Attached is a manual backport of the change in case needed.

[PATCH net V2] amd-xgbe: Fix to ensure dependent features are toggled with RX checksum offload

by Vishal Badole

According to the XGMAC specification, enabling features such as Layer 3 and Layer 4 Packet Filtering, Split Header, Receive Side Scaling (RSS), and Virtualized Network support automatically selects the IPC Full Checksum Offload Engine on the receive side. When RX checksum offload is disabled, these dependent features must also be disabled to prevent abnormal behavior caused by mismatched feature dependencies. Ensure that toggling RX checksum offload (disabling or enabling) properly disables or enables all dependent features, maintaining consistent and expected behavior in the network device. v1->v2: ------- - Combine 2 patches into a single patch - Update the "Fix: tag" - Add necessary changes to support earlier versions of the hardware as well Cc: stable(a)vger.kernel.org Fixes: 1a510ccf5869 ("amd-xgbe: Add support for VXLAN offload capabilities") Signed-off-by: Vishal Badole <Vishal.Badole(a)amd.com> --- drivers/net/ethernet/amd/xgbe/xgbe-desc.c | 9 +++++++-- drivers/net/ethernet/amd/xgbe/xgbe-dev.c | 24 +++++++++++++++++++++-- drivers/net/ethernet/amd/xgbe/xgbe-drv.c | 21 ++++++++++++++++++-- drivers/net/ethernet/amd/xgbe/xgbe.h | 4 ++++ 4 files changed, 52 insertions(+), 6 deletions(-) diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c index 230726d7b74f..d41b58fad37b 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c @@ -373,8 +373,13 @@ static int xgbe_map_rx_buffer(struct xgbe_prv_data *pdata, } /* Set up the header page info */ - xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, - XGBE_SKB_ALLOC_SIZE); + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + XGBE_SKB_ALLOC_SIZE); + } else { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + pdata->rx_buf_size); + } /* Set up the buffer page info */ xgbe_set_buffer_data(&rdata->rx.buf, &ring->rx_buf_pa, diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c index 7a923b6e83df..d0a35aab7355 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c @@ -321,6 +321,18 @@ static void xgbe_config_sph_mode(struct xgbe_prv_data *pdata) XGMAC_IOWRITE_BITS(pdata, MAC_RCR, HDSMS, XGBE_SPH_HDSMS_SIZE); } +static void xgbe_disable_sph_mode(struct xgbe_prv_data *pdata) +{ + unsigned int i; + + for (i = 0; i < pdata->channel_count; i++) { + if (!pdata->channel[i]->rx_ring) + break; + + XGMAC_DMA_IOWRITE_BITS(pdata->channel[i], DMA_CH_CR, SPH, 0); + } +} + static int xgbe_write_rss_reg(struct xgbe_prv_data *pdata, unsigned int type, unsigned int index, unsigned int val) { @@ -3750,8 +3762,12 @@ static int xgbe_init(struct xgbe_prv_data *pdata) xgbe_config_tx_coalesce(pdata); xgbe_config_rx_buffer_size(pdata); xgbe_config_tso_mode(pdata); - xgbe_config_sph_mode(pdata); - xgbe_config_rss(pdata); + + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_config_sph_mode(pdata); + xgbe_config_rss(pdata); + } + desc_if->wrapper_tx_desc_init(pdata); desc_if->wrapper_rx_desc_init(pdata); xgbe_enable_dma_interrupts(pdata); @@ -3910,5 +3926,9 @@ void xgbe_init_function_ptrs_dev(struct xgbe_hw_if *hw_if) hw_if->disable_vxlan = xgbe_disable_vxlan; hw_if->set_vxlan_id = xgbe_set_vxlan_id; + /* For Split Header*/ + hw_if->enable_sph = xgbe_config_sph_mode; + hw_if->disable_sph = xgbe_disable_sph_mode; + DBGPR("<--xgbe_init_function_ptrs\n"); } diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c index f249f89fec38..4d290ec934a8 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c @@ -2267,6 +2267,16 @@ static netdev_features_t xgbe_fix_features(struct net_device *netdev, } } + if (features & NETIF_F_RXCSUM) { + netdev_notice(netdev, + "forcing receive hashing on\n"); + features |= NETIF_F_RXHASH; + } else { + netdev_notice(netdev, + "forcing receive hashing off\n"); + features &= ~NETIF_F_RXHASH; + } + return features; } @@ -2290,10 +2300,17 @@ static int xgbe_set_features(struct net_device *netdev, if (ret) return ret; - if ((features & NETIF_F_RXCSUM) && !rxcsum) + if ((features & NETIF_F_RXCSUM) && !rxcsum) { + hw_if->enable_sph(pdata); + hw_if->enable_vxlan(pdata); hw_if->enable_rx_csum(pdata); - else if (!(features & NETIF_F_RXCSUM) && rxcsum) + schedule_work(&pdata->restart_work); + } else if (!(features & NETIF_F_RXCSUM) && rxcsum) { + hw_if->disable_sph(pdata); + hw_if->disable_vxlan(pdata); hw_if->disable_rx_csum(pdata); + schedule_work(&pdata->restart_work); + } if ((features & NETIF_F_HW_VLAN_CTAG_RX) && !rxvlan) hw_if->enable_rx_vlan_stripping(pdata); diff --git a/drivers/net/ethernet/amd/xgbe/xgbe.h b/drivers/net/ethernet/amd/xgbe/xgbe.h index db73c8f8b139..92b61a318f66 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe.h +++ b/drivers/net/ethernet/amd/xgbe/xgbe.h @@ -902,6 +902,10 @@ struct xgbe_hw_if { void (*enable_vxlan)(struct xgbe_prv_data *); void (*disable_vxlan)(struct xgbe_prv_data *); void (*set_vxlan_id)(struct xgbe_prv_data *); + + /* For Split Header */ + void (*enable_sph)(struct xgbe_prv_data *pdata); + void (*disable_sph)(struct xgbe_prv_data *pdata); }; /* This structure represents implementation specific routines for an -- 2.34.1

The first is that this sanitizer is under active development on the compiler side to come up with a solution that is maintainable on the compiler side and usable on the kernel side. As a result of this, there are many warnings when the sanitizer is enabled that have no clear path to resolution yet but users may see them and report them in the meantime. The second is that this option was renamed from CONFIG_UBSAN_SIGNED_WRAP, meaning that if a configuration has CONFIG_UBSAN=y but CONFIG_UBSAN_SIGNED_WRAP=n and it is upgraded via olddefconfig (common in non-interactive scenarios such as CI), CONFIG_UBSAN_INTEGER_WRAP will be silently enabled again. Remove 'default UBSAN' from CONFIG_UBSAN_INTEGER_WRAP until it is ready for regular usage and testing from a broader community than the folks actively working on the feature.

The first is that this sanitizer is under active development on the compiler side to come up with a solution that is maintainable on the compiler side and usable on the kernel side. As a result of this, there are many warnings when the sanitizer is enabled that have no clear path to resolution yet but users may see them and report them in the meantime. The second is that this option was renamed from CONFIG_UBSAN_SIGNED_WRAP, meaning that if a configuration has CONFIG_UBSAN=y but CONFIG_UBSAN_SIGNED_WRAP=n and it is upgraded via olddefconfig (common in non-interactive scenarios such as CI), CONFIG_UBSAN_INTEGER_WRAP will be silently enabled again. Remove 'default UBSAN' from CONFIG_UBSAN_INTEGER_WRAP until it is ready for regular usage and testing from a broader community than the folks actively working on the feature.

[PATCH 5.10/5.15/6.1] netfilter: ipt_CLUSTERIP: change mutex location

by Evgeny Pimenov

No upstream commit exists for this patch. The file ipt_CLUSTERIP.c was deleted in commit 9db5d918e2c0 ("netfilter: ip_tables: remove clusterip target"), but races still exist in stable branches. Thread A in clusterip_config_entry_put() decrements refcount and removes config from the list but doesn't call proc_remove(). Thread B searches the config, doesn't find it, re-adds it to the list, and calls proc_create_data() with an IP that still exists in the tree. |A| refcount_dec_and_lock() |A| list_del_rcu() === Must be here |A| proc_remove() === |B| __clusterip_config_find() |B| list_add_rcu() |B| proc_create_data() |B| WARN() As a fix, also cover with mutex the places of interaction with the list of configs before proc_remove() and proc_create_data() functions. ------------[ cut here ]------------ proc_dir_entry 'ipt_CLUSTERIP/100.1.1.2' already registered WARNING: CPU: 0 PID: 2597 at fs/proc/generic.c:381 proc_register+0x517/0x6e0 fs/proc/generic.c:381 [...] Call Trace: proc_create_data+0x130/0x1a0 fs/proc/generic.c:583 clusterip_config_init net/ipv4/netfilter/ipt_CLUSTERIP.c:281 [inline] clusterip_tg_check+0xb8d/0x1380 net/ipv4/netfilter/ipt_CLUSTERIP.c:502 xt_check_target+0x27c/0xa00 net/netfilter/x_tables.c:1018 check_target net/ipv4/netfilter/ip_tables.c:511 [inline] find_check_entry.constprop.0+0x7b0/0x9b0 net/ipv4/netfilter/ip_tables.c:553 translate_table+0xc6a/0x16a0 net/ipv4/netfilter/ip_tables.c:717 do_replace net/ipv4/netfilter/ip_tables.c:1138 [inline] do_ipt_set_ctl+0x54e/0xb00 net/ipv4/netfilter/ip_tables.c:1636 nf_setsockopt+0x88/0xf0 net/netfilter/nf_sockopt.c:101 ip_setsockopt+0xe4d/0x3d10 net/ipv4/ip_sockglue.c:1442 sctp_setsockopt+0x135/0xa390 net/sctp/socket.c:4475 __sys_setsockopt+0x234/0x5a0 net/socket.c:2145 __do_sys_setsockopt net/socket.c:2156 [inline] __se_sys_setsockopt net/socket.c:2153 [inline] __x64_sys_setsockopt+0xb9/0x150 net/socket.c:2153 do_syscall_64+0x30/0x40 arch/x86/entry/common.c:46 entry_SYSCALL_64_after_hwframe+0x67/0xd1 Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

This occurs on LoongArch under specific conditions. The root cause involves several steps: 1. When the hugetlbfs file is mapped (MAP_PRIVATE), the initial PMD (or relevant level) entry is often populated by the kernel during mmap() with a non-present entry pointing to the architecture's invalid_pte_table On the affected LoongArch system, this address was observed to be 0x90000000031e4000. 2. The smaps walker (walk_hugetlb_range -> smaps_hugetlb_range) reads this entry. 3. The generic is_swap_pte() macro checks `!pte_present() && !pte_none()`. The entry (invalid_pte_table address) is not present. Crucially, the generic pte_none() check (`!(pte_val(pte) & ~_PAGE_GLOBAL)`) returns false because the invalid_pte_table address is non-zero. Therefore, is_swap_pte() incorrectly returns true. 4. The code enters the `else if (is_swap_pte(...))` block. 5. Inside this block, it checks `is_pfn_swap_entry()`. Due to a bit pattern coincidence in the invalid_pte_table address on LoongArch, the embedded generic `is_migration_entry()` check happens to return true (misinterpreting parts of the address as a migration type). 6. This leads to a call to pfn_swap_entry_to_page() with the bogus swap entry derived from the invalid table address. 7. pfn_swap_entry_to_page() extracts a meaningless PFN, finds an unrelated struct page, checks its lock status (unlocked), and hits the `BUG_ON(is_migration_entry(entry) && !PageLocked(p))` assertion. The original code's intent in the `else if` block seems aimed at handling potential migration entries, as indicated by the inner `is_pfn_swap_entry()` check. The issue arises because the outer `is_swap_pte()` check incorrectly includes the invalid table pointer case on LoongArch. This patch fixes the issue by changing the condition in smaps_hugetlb_range() from the broad `is_swap_pte()` to the specific `is_hugetlb_entry_migration()`. The `is_hugetlb_entry_migration()` helper function correctly handles this by first checking `huge_pte_none()`. Architectures like LoongArch can provide an override for `huge_pte_none()` that specifically recognizes the `invalid_pte_table` address as a "none" state for HugeTLB entries. This ensures `is_hugetlb_entry_migration()` returns false for the invalid entry, preventing the code from entering the faulty block. This change makes the code reflect the likely original intent (handling migration) more accurately and leverages architecture-specific helpers (`huge_pte_none`) to correctly interpret special PTE/PMD values in the HugeTLB context, fixing the crash on LoongArch without altering the generic is_swap_pte() behavior.

[PATCH] usb: cdnsp: fix L1 resume issue for RTL_REVISION_NEW_LPM version

by Pawel Laszczak

The controllers with rtl version greeter than RTL_REVISION_NEW_LPM (0x00002700) has bug which causes that controller doesn't resume from L1 state. It happens if after receiving LPM packet controller starts transitioning to L1 and in this moment the driver force resuming by write operation to PORTSC.PLS. It's corner case and happens when write operation to PORTSC occurs during device delay before transitioning to L1 after transmitting ACK time (TL1TokenRetry). Forcing transition from L1->L0 by driver for revision greeter than RTL_REVISION_NEW_LPM is not needed, so driver can simply fix this issue through block call of cdnsp_force_l0_go function.

[PATCH] HID: amd_sfh: Fix SRA sensor when it's the only sensor

by Mario Limonciello

From: Mario Limonciello <mario.limonciello(a)amd.com> On systems that only have an SRA sensor connected to SFH the sensor doesn't get enabled due to a bad optimization condition of breaking the sensor walk loop. This optimization is unnecessary in the first place because if there is only one device then the loop only runs once. Drop the condition and explicitly mark sensor as enabled.

[PATCH v2 RESEND] HID: wacom: fix shift OOB in kfifo allocation for zero pktlen

by Qasim Ijaz

During wacom_parse_and_register() the code calls wacom_devm_kfifo_alloc to allocate a fifo. During this operation it passes kfifo_alloc a fifo_size of 0. Kfifo attempts to round the size passed to it to the next power of 2 via roundup_pow_of_two (queue-type data structures do this to maintain efficiency of operations). However during this phase a problem arises when the roundup_pow_of_two() function utilises a shift exponent of fls_long(n-1), where n is the fifo_size. Since n is 0 in this case and n is also an unsigned long, doing n-1 causes unsigned integer wrap-around to occur making the fifo_size 4294967295. So the code effectively does fls_long(4294967295) which results in 64. Returning back to roundup_pow_of_two(), the code utilises a shift exponent of 64. When a shift exponent of 64 is used on a 64-bit type such as 1UL it results in a shift-out-of-bounds. The root cause of the issue seems to stem from insufficient validation of wacom_compute_pktlen(), since in this case the fifo_size comes from wacom_wac->features.pktlen. During wacom_parse_and_register() the wacom_compute_pktlen() function sets the pktlen as 0. To fix this, we should handle cases where wacom_compute_pktlen() results in 0.

[PATCH v1] HID: usbhid: Eliminate recurrent out-of-bounds bug in usbhid_parse()

by Terry Junge

Update struct hid_descriptor to better reflect the mandatory and optional parts of the HID Descriptor as per USB HID 1.11 specification. Note: the kernel currently does not parse any optional HID class descriptors, only the mandatory report descriptor. Update all references to member element desc[0] to rpt_desc. Add test to verify bLength and bNumDescriptors values are valid. Replace the for loop with direct access to the mandatory HID class descriptor member for the report descriptor. This eliminates the possibility of getting an out-of-bounds fault. Add a warning message if the HID descriptor contains any unsupported optional HID class descriptors.

[PATCH v3] arm64: dts: imx8mm-verdin: Link reg_usdhc2_vqmmc to usdhc2

by Wojciech Dubowik

[PATCH 5.10.y] perf: Fix perf_pending_task() UaF

by Xiangyu Chen

From: Peter Zijlstra <peterz(a)infradead.org> [ Upstream commit 517e6a301f34613bff24a8e35b5455884f2d83d8 ] Per syzbot it is possible for perf_pending_task() to run after the event is free()'d. There are two related but distinct cases: - the task_work was already queued before destroying the event; - destroying the event itself queues the task_work. The first cannot be solved using task_work_cancel() since perf_release() itself might be called from a task_work (____fput), which means the current->task_works list is already empty and task_work_cancel() won't be able to find the perf_pending_task() entry. The simplest alternative is extending the perf_event lifetime to cover the task_work. The second is just silly, queueing a task_work while you know the event is going away makes no sense and is easily avoided by re-arranging how the event is marked STATE_DEAD and ensuring it goes through STATE_OFF on the way down.

[PATCH v2 1/1] iommu: Allow attaching static domains in iommu_attach_device_pasid()

by Lu Baolu

The idxd driver attaches the default domain to a PASID of the device to perform kernel DMA using that PASID. The domain is attached to the device's PASID through iommu_attach_device_pasid(), which checks if the domain->owner matches the iommu_ops retrieved from the device. If they do not match, it returns a failure. if (ops != domain->owner || pasid == IOMMU_NO_PASID) return -EINVAL; The static identity domain implemented by the intel iommu driver doesn't specify the domain owner. Therefore, kernel DMA with PASID doesn't work for the idxd driver if the device translation mode is set to passthrough. Generally the owner field of static domains are not set because they are already part of iommu ops. Add a helper domain_iommu_ops_compatible() that checks if a domain is compatible with the device's iommu ops. This helper explicitly allows the static blocked and identity domains associated with the device's iommu_ops to be considered compatible.

And the root cause is that it has too much free memory than what the test supports. The test case tries to allocate 100000 huge pages, which is about 200 GB for that x86 server, and when it succeeds, it expects it's large than 1/3 of 80% of the free memory in system. This logic only works for platform with 750 GB ( 200 / (1/3) / 80% ) or less free memory, and may raise false alarm for others. Fix it by changing the fixed page number to self-adjustable number according to the real number of free memory.

[PATCH v4 5/6] media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

by Mathis Foerst

Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().

[PATCH 5.15.y] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI

by bin.lan.cn＠windriver.com

From: James Smart <jsmart2021(a)gmail.com> [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

[PATCH v2 1/2] drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()

by Philipp Stanner

Nouveau is mostly designed in a way that it's expected that fences only ever get signaled through nouveau_fence_signal(). However, in at least one other place, nouveau_fence_done(), can signal fences, too. If that happens (race) a signaled fence remains in the pending list for a while, until it gets removed by nouveau_fence_update(). Should nouveau_fence_context_kill() run in the meantime, this would be a bug because the function would attempt to set an error code on an already signaled fence. Have nouveau_fence_context_kill() check for a fence being signaled.

[tip: x86/urgent] x86/mm: Fix _pgd_alloc() for Xen PV mode

by tip-bot2 for Juergen Gross

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 4ce385f56434f3810ef103e1baea357ddcc6667e Gitweb: https://git.kernel.org/tip/4ce385f56434f3810ef103e1baea357ddcc6667e Author: Juergen Gross <jgross(a)suse.com> AuthorDate: Tue, 22 Apr 2025 15:17:17 +02:00 Committer: Dave Hansen <dave.hansen(a)linux.intel.com> CommitterDate: Wed, 23 Apr 2025 07:49:14 -07:00 x86/mm: Fix _pgd_alloc() for Xen PV mode Recently _pgd_alloc() was switched from using __get_free_pages() to pagetable_alloc_noprof(), which might return a compound page in case the allocation order is larger than 0. On x86 this will be the case if CONFIG_MITIGATION_PAGE_TABLE_ISOLATION is set, even if PTI has been disabled at runtime. When running as a Xen PV guest (this will always disable PTI), using a compound page for a PGD will result in VM_BUG_ON_PGFLAGS being triggered when the Xen code tries to pin the PGD. Fix the Xen issue together with the not needed 8k allocation for a PGD with PTI disabled by replacing PGD_ALLOCATION_ORDER with an inline helper returning the needed order for PGD allocations.

[PATCH] fs/nfs/read: fix double-unlock bug in nfs_return_empty_folio()

by Max Kellermann

Sometimes, when a file was read while it was being truncated by another NFS client, the kernel could deadlock because folio_unlock() was called twice, and the second call would XOR back the `PG_locked` flag. Most of the time (depending on the timing of the truncation), nobody notices the problem because folio_unlock() gets called three times, which flips `PG_locked` back off: 1. vfs_read, nfs_read_folio, ... nfs_read_add_folio, nfs_return_empty_folio 2. vfs_read, nfs_read_folio, ... netfs_read_collection, netfs_unlock_abandoned_read_pages 3. vfs_read, ... nfs_do_read_folio, nfs_read_add_folio, nfs_return_empty_folio The problem is that nfs_read_add_folio() is not supposed to unlock the folio if fscache is enabled, and a nfs_netfs_folio_unlock() check is missing in nfs_return_empty_folio(). Rarely this leads to a warning in netfs_read_collection(): ------------[ cut here ]------------ R=0000031c: folio 10 is not locked WARNING: CPU: 0 PID: 29 at fs/netfs/read_collect.c:133 netfs_read_collection+0x7c0/0xf00 [...] Workqueue: events_unbound netfs_read_collection_worker RIP: 0010:netfs_read_collection+0x7c0/0xf00 [...] Call Trace: <TASK> netfs_read_collection_worker+0x67/0x80 process_one_work+0x12e/0x2c0 worker_thread+0x295/0x3a0 Most of the time, however, processes just get stuck forever in folio_wait_bit_common(), waiting for `PG_locked` to disappear, which never happens because nobody is really holding the folio lock.

[PATCH v5.4.y] usb: dwc3: core: Do core softreset when switch mode

by Hardik Gohil

From: Yu Chen <chenyu56(a)huawei.com> commit f88359e1588b85cf0e8209ab7d6620085f3441d9 upstream. From: John Stultz <john.stultz(a)linaro.org> According to the programming guide, to switch mode for DRD controller, the driver needs to do the following. To switch from device to host: 1. Reset controller with GCTL.CoreSoftReset 2. Set GCTL.PrtCapDir(host mode) 3. Reset the host with USBCMD.HCRESET 4. Then follow up with the initializing host registers sequence To switch from host to device: 1. Reset controller with GCTL.CoreSoftReset 2. Set GCTL.PrtCapDir(device mode) 3. Reset the device with DCTL.CSftRst 4. Then follow up with the initializing registers sequence Currently we're missing step 1) to do GCTL.CoreSoftReset and step 3) of switching from host to device. John Stult reported a lockup issue seen with HiKey960 platform without these steps[1]. Similar issue is observed with Ferry's testing platform[2]. So, apply the required steps along with some fixes to Yu Chen's and John Stultz's version. The main fixes to their versions are the missing wait for clocks synchronization before clearing GCTL.CoreSoftReset and only apply DCTL.CSftRst when switching from host to device.

[PATCH 0/2] regulator: max20086: Fixes chip id and enable gpio

by João Paulo Gonçalves

Hello, I'm working on integrating a system with a MAX20086 and noticed these small issues in the driver: the chip ID for MAX20086 is 0x30 and not 0x40. Also, in my use case, the enable pin is always enabled by hardware, so the enable GPIO isn't needed. Without these changes, the driver fails to probe.

[PATCH] usb: typec: ucsi: fix Clang -Wsign-conversion warning

by Qasim Ijaz

debugfs.c emits the following warnings when compiling with the -Wsign-conversion flag with clang 15: drivers/usb/typec/ucsi/debugfs.c:58:27: warning: implicit conversion changes signedness: 'int' to 'u32' (aka 'unsigned int') [-Wsign-conversion] ucsi->debugfs->status = ret; ~ ^~~ drivers/usb/typec/ucsi/debugfs.c:71:25: warning: implicit conversion changes signedness: 'u32' (aka 'unsigned int') to 'int' [-Wsign-conversion] return ucsi->debugfs->status; ~~~~~~ ~~~~~~~~~~~~~~~^~~~~~ During ucsi_cmd() we see: if (ret < 0) { ucsi->debugfs->status = ret; return ret; } But "status" is u32 meaning unsigned wrap-around occurs when assigning a value which is < 0 to it, this obscures the real status. To fix this make the "status" of type int since ret is also of type int.

[PATCH stable 6.12 0/8] bpf: track changes_pkt_data property for global functions

by Shung-Hsi Yu

While stable 6.12 has commit 1a4607ffba35 ("bpf: consider that tail calls invalidate packet pointers") backported, that alone is not enough to fix the issue reported by Nick Zavaritsky[1]. This is evident when running the verifier_sock/invalidate_pkt_pointers_from_global_func and verifier_sock/invalidate_pkt_pointers_by_tail_call BPF selftests[2]. Error: #529 verifier_sock Error: #529/57 verifier_sock/invalidate_pkt_pointers_from_global_func run_subtest:PASS:obj_open_mem 0 nsec run_subtest:FAIL:unexpected_load_success unexpected success: 0 Error: #529/58 verifier_sock/invalidate_pkt_pointers_by_tail_call run_subtest:PASS:obj_open_mem 0 nsec run_subtest:FAIL:unexpected_load_success unexpected success: 0 Fix the issue by backporting the entire "bpf: track changes_pkt_data property for global functions" series[3], along with the follow up, "bpf: fix NPE when computing changes_pkt_data of program w/o subprograms" series[4]; both from Eduard. With this series applied the test above no longer fails[5]. 1: https://lore.kernel.org/bpf/0498CA22-5779-4767-9C0C-A9515CEA711F@gmail.com/ 2: https://github.com/shunghsiyu/libbpf/actions/runs/14591085098/job/409263031… 3: https://lore.kernel.org/all/20241210041100.1898468-1-eddyz87@gmail.com/ 4: https://lore.kernel.org/all/20241212070711.427443-1-eddyz87@gmail.com/ 5: https://github.com/shunghsiyu/libbpf/actions/runs/14609494070/job/409847569… Eduard Zingerman (8): bpf: add find_containing_subprog() utility function bpf: track changes_pkt_data property for global functions selftests/bpf: test for changing packet data from global functions bpf: check changes_pkt_data property for extension programs selftests/bpf: freplace tests for tracking of changes_packet_data selftests/bpf: validate that tail call invalidates packet pointers bpf: fix null dereference when computing changes_pkt_data of prog w/o subprogs selftests/bpf: extend changes_pkt_data with cases w/o subprograms include/linux/bpf.h | 1 + include/linux/bpf_verifier.h | 1 + kernel/bpf/verifier.c | 79 +++++++++++-- .../bpf/prog_tests/changes_pkt_data.c | 107 ++++++++++++++++++ .../selftests/bpf/progs/changes_pkt_data.c | 39 +++++++ .../bpf/progs/changes_pkt_data_freplace.c | 18 +++ .../selftests/bpf/progs/verifier_sock.c | 56 +++++++++ 7 files changed, 292 insertions(+), 9 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/changes_pkt_data.c create mode 100644 tools/testing/selftests/bpf/progs/changes_pkt_data.c create mode 100644 tools/testing/selftests/bpf/progs/changes_pkt_data_freplace.c -- 2.49.0

[PATCH 5.15.y] xfs: add bounds checking to xlog_recover_process_data

by Zhi Yang

From: lei lu <llfamsec(a)gmail.com> commit fb63435b7c7dc112b1ae1baea5486e0a6e27b196 upstream. There is a lack of verification of the space occupied by fixed members of xlog_op_header in the xlog_recover_process_data. We can create a crafted image to trigger an out of bounds read by following these steps: 1) Mount an image of xfs, and do some file operations to leave records 2) Before umounting, copy the image for subsequent steps to simulate abnormal exit. Because umount will ensure that tail_blk and head_blk are the same, which will result in the inability to enter xlog_recover_process_data 3) Write a tool to parse and modify the copied image in step 2 4) Make the end of the xlog_op_header entries only 1 byte away from xlog_rec_header->h_size 5) xlog_rec_header->h_num_logops++ 6) Modify xlog_rec_header->h_crc Fix: Add a check to make sure there is sufficient space to access fixed members of xlog_op_header.

[PATCH v2] staging: bcm2835-camera: Initialise dev in v4l2_dev

by Dave Stevenson

Commit 42a2f6664e18 ("staging: vc04_services: Move global g_state to vchiq_state") changed mmal_init to pass dev->v4l2_dev.dev to vchiq_mmal_init, however nothing iniitialised dev->v4l2_dev, so we got a NULL pointer dereference. Set dev->v4l2_dev.dev during bcm2835_mmal_probe. The device pointer could be passed into v4l2_device_register to set it, however that also has other effects that would need additional changes.

[PATCH] Input: cyttsp5 - fix power control issue on wakeup

by Hugo Villeneuve

From: Mikael Gonella-Bolduc <mgonellabolduc(a)dimonoff.com> The power control function ignores the "on" argument when setting the report ID, and thus is always sending HID_POWER_SLEEP. This causes a problem when trying to wakeup. Fix by sending the state variable, which contains the proper HID_POWER_ON or HID_POWER_SLEEP based on the "on" argument.

[PATCH 1/1] iommu/vt-d: Assign owner to the static identity domain

by Lu Baolu

The idxd driver attaches the default domain to a PASID of the device to perform kernel DMA using that PASID. The domain is attached to the device's PASID through iommu_attach_device_pasid(), which checks if the domain->owner matches the iommu_ops retrieved from the device. If they do not match, it returns a failure. if (ops != domain->owner || pasid == IOMMU_NO_PASID) return -EINVAL; The static identity domain implemented by the intel iommu driver doesn't specify the domain owner. Therefore, kernel DMA with PASID doesn't work for the idxd driver if the device translation mode is set to passthrough. Fix this by specifying the domain owner for the static identity domain.

[PATCH RESEND] drm/amdgpu: Remove redundant return value checks for amdgpu_ras_error_data_init

by Wentao Liang

The function amdgpu_ras_error_data_init() always returns 0, making its return value checks redundant. This patch changes its return type to void and removes all unnecessary checks in the callers. This simplifies the code and avoids confusion about the function's behavior. Additionally, this change keeps the usage consistent with amdgpu_ras_do_page_retirement(), which also does not check the return value.

This means that calling WMI methods on this WMI device is not thread-safe, as concurrent WMI method calls will corrupt the global buffer. Fix this by serializing the WMI method calls using a mutex.

[PATCH] video: screen_info: Update framebuffers behind PCI bridges

by Thomas Zimmermann

Apply bridge window offsets to screen_info framebuffers during relocation. Fixes invalid access to I/O memory. Resources behind a PCI bridge can be located at a certain offset in the kernel's I/O range. The framebuffer memory range stored in screen_info refers to the offset as seen during boot (essentialy 0). During boot up, the kernel may assign a different memory offset to the bridge device and thereby relocating the framebuffer address of the PCI graphics device as seen by the kernel. The information in screen_info must be updated as well. The helper pcibios_bus_to_resource() performs the relocation of the screen_info resource. The result now matches the I/O-memory resource of the PCI graphics device. As before, we store away the information necessary to update the information in screen_info. Commit 78aa89d1dfba ("firmware/sysfb: Update screen_info for relocated EFI framebuffers") added the code for updating screen_info. It is based on similar functionality that pre-existed in efifb. But efifb did not handle bridges correctly, so the problem presumably exists only on newer systems. Signed-off-by: Thomas Zimmermann <tzimmermann(a)suse.de> Reported-by: Tested-by: "Ivan T.
