[PATCH 00/20] Add support for HEVC and VP9 codecs in decoder

by Dikshita Agarwal

Hi All, This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs. These patches also address the comments and feedback received from the RFC patches previously sent. I have made the necessary improvements based on the community's suggestions. Changes sinces RFC: - Added additional fixes to address issues identified during further testing. - Moved typo fix to a seperate patch [Neil] - Reordered the patches for better logical flow and clarity [Neil, Dmitry] - Added fixes tag wherever applicable [Neil, Dmitry] - Removed the default case in the switch statement for codecs [Bryan] - Replaced if-else statements with switch-case [Bryan] - Added comments for mbpf [Bryan] - RFC: https://lore.kernel.org/linux-media/20250305104335.3629945-1-quic_dikshita@… These patches are tested on SM8250 and SM8550 with v4l2-ctl and Gstreamer for HEVC and VP9 decoders, at the same time ensured that the existing H264 decoder functionality remains uneffected. Note: 1 of the fluster compliance test is fixed with firmware [1] [1]: https://lore.kernel.org/linux-firmware/1a511921-446d-cdc4-0203-084c88a5dc1e… The result of fluster test on SM8550: 131/147 testcases passed while testing JCT-VC-HEVC_V1 with GStreamer-H.265-V4L2-Gst1.0. The failing test case: - 10 testcases failed due to unsupported 10 bit format. - DBLK_A_MAIN10_VIXS_4 - INITQP_B_Main10_Sony_1 - TSUNEQBD_A_MAIN10_Technicolor_2 - WP_A_MAIN10_Toshiba_3 - WP_MAIN10_B_Toshiba_3 - WPP_A_ericsson_MAIN10_2 - WPP_B_ericsson_MAIN10_2 - WPP_C_ericsson_MAIN10_2 - WPP_E_ericsson_MAIN10_2 - WPP_F_ericsson_MAIN10_2 - 4 testcase failed due to unsupported resolution - PICSIZE_A_Bossen_1 - PICSIZE_B_Bossen_1 - WPP_D_ericsson_MAIN10_2 - WPP_D_ericsson_MAIN_2 - 1 testcase failed as bitstream is invalid (this fails with reference as well) - RAP_B_Bossen_2 - 1 testcase failed due to CRC mismatch - RAP_A_docomo_6 Analysis - First few frames in this discarded by firmware and are sent to driver with 0 filled length. Driver send such buffers to client with timestamp 0 and payload set to 0 and make buf state to VB2_BUF_STATE_ERROR. Such buffers should be dropped by GST. But instead, the first frame displayed as green frame and when a valid buffer is sent to client later with same 0 timestamp, its dropped, leading to CRC mismatch for first frame. 235/305 testcases passed while testing VP9-TEST-VECTORS with GStreamer-VP9-V4L2-Gst1.0.

Where firmware returned all the buffers with previous sequence and has no buffer left to attach the LAST flag to. At the same time, client is not queueing any further buffers, so there is deadlock where client is waiting for LAST flag, while firmware doesn't have any capture buffer to attach LAST flag to. Ideally client should keep queueing the buffers on capture queue untill the LAST flag is received.

[PATCH 0/9] fs: harden anon inodes

by Christian Brauner

* Anonymous inodes currently don't come with a proper mode causing issues in the kernel when we want to add useful VFS debug assert. Fix that by giving them a proper mode and masking it off when we report it to userspace which relies on them not having any mode. * Anonymous inodes currently allow to change inode attributes because the VFS falls back to simple_setattr() if i_op->setattr isn't implemented. This means the ownership and mode for every single user of anon_inode_inode can be changed. Block that as it's either useless or actively harmful. If specific ownership is needed the respective subsystem should allocate anonymous inodes from their own private superblock. * Port pidfs to the new anon_inode_{g,s}etattr() helpers. * Add proper tests for anonymous inode behavior. The anonymous inode specific fixes should ideally be backported to all LTS kernels.

[PATCH] drm/tegra: Assign plane type before registration

by Aaron Kling via B4 Relay

From: Thierry Reding <treding(a)nvidia.com> Changes to a plane's type after it has been registered aren't propagated to userspace automatically. This could possibly be achieved by updating the property, but since we can already determine which type this should be before the registration, passing in the right type from the start is a much better solution.

BUG: perf hardware breakpoint pc value mismatch

by liaochen (A)

Hi all, We found the following issue with Linux v6.12-rc7 on KunPeng920 platform. A very low frequency problem of pc value mismatch occurs when using perf hardware breakpoints to trigger a signal handler and comparing pc from u_context with its desired value. Attached please find the reproducer for this issue. It applies perf events to set a hardware breakpoint to an address while binding a signal to the perf event fd. When stepping into the breakpoint address, the signal handler compares pc value copied from signal ucontext with the real breakpoint address and see if there is a mismatch. While looking into the flow of execution: // normal flow of exe: a.out-19844 [038] d... 8763.348609: hw_breakpoint_control: perf user addr: 400c6c, bp addr: 400c6c, ops: 0 // breakpoint exception: a.out-19844 [038] d... 8763.348611: do_debug_exception: ec: 0, pc: 400c6c, pstate: 20001000 a.out-19844 [038] d... 8763.348611: breakpoint_handler: perf bp read: 400c6c // send signal: a.out-19844 [038] d.h. 8763.348613: send_sigio_to_task <-send_sigio a.out-19844 [038] d.h. 8763.348614: <stack trace> => send_sigio_to_task => send_sigio => kill_fasync_rcu => kill_fasync => perf_event_wakeup => perf_pending_event => irq_work_single => irq_work_run_list => irq_work_run => do_handle_IPI => ipi_handler => handle_percpu_devid_fasteoi_ipi => __handle_domain_irq => gic_handle_irq => el0_irq_naked a.out-19844 [038] d.h. 8763.348614: send_sigio_to_task: step in with signum 38 a.out-19844 [038] d.h. 8763.348615: send_sigio_to_task: will do_send_sig_info 38 // kernel signal handling: a.out-19844 [038] .... 8763.348616: do_notify_resume: thread_flags 2097665, _TIF_SIGPENDING 1, _TIF_NOTIFY_SIGNAL40 a.out-19844 [038] .... 8763.348617: setup_sigframe: restore sig: 400c6c // single step exception: a.out-19844 [038] d... 8763.348619: do_debug_exception: ec: 1, pc: 400988, pstate: 20001000 a.out-19844 [038] d... 8763.348621: hw_breakpoint_control: perf user addr: 400c6c, bp addr: 400c6c, ops: 1 // abnormal flow of exe: a.out-19844 [084] d... 8763.782103: hw_breakpoint_control: perf user addr: 400c6c, bp addr: 400c6c, ops: 0 // breakpoint exception: a.out-19844 [084] d... 8763.782104: do_debug_exception: ec: 0, pc: 400c6c, pstate: 20001000 // single step exception: a.out-19844 [084] d... 8763.782105: breakpoint_handler: perf bp read: 400c6c a.out-19844 [084] d... 8763.782107: do_debug_exception: ec: 1, pc: 400c70, pstate: 20001000 // send signal: a.out-19844 [084] d.h. 8763.782108: send_sigio_to_task <-send_sigio a.out-19844 [084] d.h. 8763.782109: <stack trace> => send_sigio_to_task => send_sigio => kill_fasync_rcu => kill_fasync => perf_event_wakeup => perf_pending_event => irq_work_single => irq_work_run_list => irq_work_run => do_handle_IPI => ipi_handler => handle_percpu_devid_fasteoi_ipi => __handle_domain_irq => gic_handle_irq => el0_irq_naked a.out-19844 [084] d.h. 8763.782110: send_sigio_to_task: step in with signum 38 a.out-19844 [084] d.h. 8763.782110: send_sigio_to_task: will do_send_sig_info 38 // kernel signal handling: a.out-19844 [084] .... 8763.782111: do_notify_resume: thread_flags 513, _TIF_SIGPENDING 1, _TIF_NOTIFY_SIGNAL40 a.out-19844 [084] .... 8763.782113: setup_sigframe: restore sig: 400c70 a.out-19844 [084] d... 8763.782115: hw_breakpoint_control: perf user addr: 400c6c, bp addr: 400c6c, ops: 1 Kernel sends this signal to task through pushing a perf_pending_event (which sends the signal) in irq_work_queue then triggering an IPI to let kernel handle this pended task. seems that when mismatch occurs, the IPI does not preempt the breakpoint exception it should preempt, causing no pending signals to be handled. In this way, there is no pending signals in do_notify_resume and kernel will not set up signal frame with correct pc value. Thanks, Chen

[PATCH v2] usb: cdnsp: Fix issue with resuming from L1

by Pawel Laszczak

In very rare cases after resuming controller from L1 to L0 it reads registers before the clock UTMI have been enabled and as the result driver reads incorrect value. Most of registers are in APB domain clock but some of them (e.g. PORTSC) are in UTMI domain clock. After entering to L1 state the UTMI clock can be disabled. When controller transition from L1 to L0 the port status change event is reported and in interrupt runtime function driver reads PORTSC. During this read operation controller synchronize UTMI and APB domain but UTMI clock is still disabled and in result it reads 0xFFFFFFFF value. To fix this issue driver increases APB timeout value. The issue is platform specific and if the default value of APB timeout is not sufficient then this time should be set Individually for each platform.

[PATCH v3 1/3] iio: frequency: 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.

Linux 6.13.12

by Greg Kroah-Hartman

I'm announcing the release of the 6.13.12 kernel. NOTE, this is the LAST version of the 6.13.y kernel tree. It is now end-of-life, everyone should move to the 6.14.y kernel branch at this point in time. The updated 6.13.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.13.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/admin-guide/kernel-parameters.txt | 2 Documentation/arch/arm64/silicon-errata.rst | 2 Documentation/devicetree/bindings/arm/qcom,coresight-tpda.yaml | 3 Documentation/devicetree/bindings/arm/qcom,coresight-tpdm.yaml | 3 Documentation/devicetree/bindings/media/i2c/st,st-mipid02.yaml | 2 Makefile | 5 arch/arm64/Kconfig | 9 arch/arm64/boot/dts/exynos/google/gs101.dtsi | 1 arch/arm64/boot/dts/mediatek/mt8173.dtsi | 6 arch/arm64/boot/dts/mediatek/mt8188.dtsi | 2 arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767.dtsi | 7 arch/arm64/boot/dts/ti/k3-j784s4-j742s2-main-common.dtsi | 6 arch/arm64/include/asm/cputype.h | 4 arch/arm64/include/asm/kvm_arm.h | 4 arch/arm64/include/asm/spectre.h | 1 arch/arm64/include/asm/traps.h | 4 arch/arm64/kernel/proton-pack.c | 218 ++- arch/arm64/kvm/arm.c | 6 arch/arm64/kvm/sys_regs.c | 204 +-- arch/arm64/mm/mmu.c | 3 arch/powerpc/kvm/powerpc.c | 5 arch/s390/Makefile | 2 arch/s390/kernel/perf_cpum_cf.c | 9 arch/s390/kernel/perf_cpum_sf.c | 3 arch/s390/pci/pci_bus.c | 3 arch/s390/pci/pci_mmio.c | 18 arch/sparc/include/asm/pgtable_64.h | 2 arch/sparc/mm/tlb.c | 5 arch/x86/Kbuild | 4 arch/x86/Kconfig | 20 arch/x86/include/asm/irqflags.h | 40 arch/x86/include/asm/paravirt.h | 20 arch/x86/include/asm/paravirt_types.h | 3 arch/x86/kernel/acpi/boot.c | 11 arch/x86/kernel/cpu/amd.c | 2 arch/x86/kernel/e820.c | 17 arch/x86/kernel/head64.c | 2 arch/x86/kernel/paravirt.c | 14 arch/x86/kernel/signal_32.c | 62 -

[PATCH] iio: ad5933: Correct settling cycles encoding per datasheet

by Gabriel Shahrouzi

Implement the settling cycles encoding as specified in the AD5933 datasheet, Table 13 ("Number of Settling Times Cycles Register"). The previous logic did not correctly translate the user-requested effective cycle count into the required 9-bit base + 2-bit multiplier format (D10..D0) for values exceeding 511. Clamp the user input for out_altvoltage0_settling_cycles to the maximum effective value of 2044 cycles (511 * 4x multiplier).

[PATCH] iio: adis16201: Correct accelerometer scale factor

by Gabriel Shahrouzi

The IIO_CHAN_INFO_SCALE previously reported for accelerometer channels used 0.4624 mg/LSB. This value matches the datasheet specification for the offset calibration registers (X/YACCL_OFFS_REG, pg 18). However, the scale should reflect the sensor output data registers (X/YACCL_OUT, pg 15, Tables 7 & 8), which use 0.4625 mg/LSB. This is also consistent with the typical sensitivity in Table 1 (1 / 2.162 ≈ 0.4625).

[PATCH 1/5] staging: iio: adc: ad7816: Allow channel 7 for all devices

by Gabriel Shahrouzi

According to the datasheet on page 9 under the channel selection table, all devices (AD7816/7/8) are able to use the channel marked as 7. This channel is used for diagnostic purposes by routing the internal 1.23V bandgap source through the MUX to the input of the ADC. Modify the channel validation logic to permit channel 7 for all supported device types.

[PATCH 5.15.y] sched/task_stack: fix object_is_on_stack() for KASAN tagged pointers

by Zhi Yang

From: Qun-Wei Lin <qun-wei.lin(a)mediatek.com> commit fd7b4f9f46d46acbc7af3a439bb0d869efdc5c58 upstream. When CONFIG_KASAN_SW_TAGS and CONFIG_KASAN_STACK are enabled, the object_is_on_stack() function may produce incorrect results due to the presence of tags in the obj pointer, while the stack pointer does not have tags. This discrepancy can lead to incorrect stack object detection and subsequently trigger warnings if CONFIG_DEBUG_OBJECTS is also enabled.

[PATCH 5.10.y] drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()

by Feng Liu

From: Duoming Zhou <duoming(a)zju.edu.cn> [ Upstream commit cc7ad0d77b51c872d629bcd98aea463a3c4109e7 ] There is a deadlock in rtw_surveydone_event_callback(), which is shown below: (Thread 1) | (Thread 2) | _set_timer() rtw_surveydone_event_callback()| mod_timer() spin_lock_bh() //(1) | (wait a time) ... | rtw_scan_timeout_handler() del_timer_sync() | spin_lock_bh() //(2) (wait timer to stop) | ... We hold pmlmepriv->lock in position (1) of thread 1 and use del_timer_sync() to wait timer to stop, but timer handler also need pmlmepriv->lock in position (2) of thread 2. As a result, rtw_surveydone_event_callback() will block forever. This patch extracts del_timer_sync() from the protection of spin_lock_bh(), which could let timer handler to obtain the needed lock. What`s more, we change spin_lock_bh() in rtw_scan_timeout_handler() to spin_lock_irq(). Otherwise, spin_lock_bh() will also cause deadlock() in timer handler.

For instance, this applies when a restriction was previously too restrictive and is now getting relaxed (e.g. for compatibility reasons). However, non-visible changes for legitimate use (e.g. security fixes) do not require an erratum. Because fixes are backported down to a specific Landlock ABI, we need a way to avoid cherry-pick conflicts. The solution is to only update a file related to the lower ABI impacted by this issue. All the ABI files are then used to create a bitmask of fixes. The new errata interface is similar to the one used to get the supported Landlock ABI version, but it returns a bitmask instead because the order of fixes may not match the order of versions, and not all fixes may apply to all versions. The actual errata will come with dedicated commits. The description is not actually used in the code but serves as documentation. Create the landlock_abi_version symbol and use its value to check errata consistency. Update test_base's create_ruleset_checks_ordering tests and add errata tests.

[PATCH 5.15.y] net: defer final 'struct net' free in netns dismantle

by jianqi.ren.cn＠windriver.com

From: Eric Dumazet <edumazet(a)google.com> [ Upstream commit 0f6ede9fbc747e2553612271bce108f7517e7a45 ] Ilya reported a slab-use-after-free in dst_destroy [1] Issue is in xfrm6_net_init() and xfrm4_net_init() : They copy xfrm[46]_dst_ops_template into net->xfrm.xfrm[46]_dst_ops. But net structure might be freed before all the dst callbacks are called. So when dst_destroy() calls later : if (dst->ops->destroy) dst->ops->destroy(dst); dst->ops points to the old net->xfrm.xfrm[46]_dst_ops, which has been freed. See a relevant issue fixed in : ac888d58869b ("net: do not delay dst_entries_add() in dst_release()") A fix is to queue the 'struct net' to be freed after one another cleanup_net() round (and existing rcu_barrier()) [1] BUG: KASAN: slab-use-after-free in dst_destroy (net/core/dst.c:112) Read of size 8 at addr ffff8882137ccab0 by task swapper/37/0 Dec 03 05:46:18 kernel: CPU: 37 UID: 0 PID: 0 Comm:

[PATCH 5.15.y v2 0/1] Manual Backport of 099606a7b2d5 to 5.15

by Harshvardhan Jha

The patch 099606a7b2d5 didn't cleanly apply to 5.15 due to the significant difference in codebases. I've tried to manually bring it back to 5.15 via some minor conflict resolution but also invoking the newly introduced API using inverted logic as the conditional statements present in 5.15 are the opposite of those in 6.1 xen/swiotlib.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From baaef0a274cfb75f9b50eab3ef93205e604f662c Mon Sep 17 00:00:00 2001 From: Kunihiko Hayashi <hayashi.kunihiko(a)socionext.com> Date: Tue, 25 Feb 2025 20:02:50 +0900 Subject: [PATCH] misc: pci_endpoint_test: Fix 'irq_type' to convey the correct type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are two variables that indicate the interrupt type to be used in the next test execution, "irq_type" as global and "test->irq_type". The global is referenced from pci_endpoint_test_get_irq() to preserve the current type for ioctl(PCITEST_GET_IRQTYPE).

IPV6_V6ONLY support for the setsockopt part has been added a while ago, but it looks like the get part got forgotten. It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types. Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want to check the default value, before doing extra actions. On Linux, the default value is 0, but this can be changed with the net.ipv6.bindv6only sysctl knob. On Windows, it is set to 1 by default. So supporting the get part, like for all other socket options, is important. Everything was in place to expose it, just the last step was missing. Only new code is added to cover this specific getsockopt(), that seems safe.

IP(V6)_FREEBIND and IP(V6)_TRANSPARENT support for the setsockopt part has been added a while ago, but it looks like the get part got forgotten. It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types.

For instance, this applies when a restriction was previously too restrictive and is now getting relaxed (e.g. for compatibility reasons). However, non-visible changes for legitimate use (e.g. security fixes) do not require an erratum. Because fixes are backported down to a specific Landlock ABI, we need a way to avoid cherry-pick conflicts. The solution is to only update a file related to the lower ABI impacted by this issue. All the ABI files are then used to create a bitmask of fixes. The new errata interface is similar to the one used to get the supported Landlock ABI version, but it returns a bitmask instead because the order of fixes may not match the order of versions, and not all fixes may apply to all versions. The actual errata will come with dedicated commits. The description is not actually used in the code but serves as documentation. Create the landlock_abi_version symbol and use its value to check errata consistency. Update test_base's create_ruleset_checks_ordering tests and add errata tests. This commit is backportable down to the first version of Landlock.

[PATCH] 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. Fixes: 7243b93345f7 ("xen/pvh: Bootstrap PVH guest") Tested-by: Jason Andryuk <jason.andryuk(a)amd.com> Reviewed-by: Jason Andryuk <jason.andryuk(a)amd.com> Signed-off-by: Ard Biesheuvel <ardb(a)kernel.org> Message-ID: <20241009160438.3884381-8-ardb+git(a)google.com> Signed-off-by: Juergen Gross <jgross(a)suse.com> [ Stable context update ] Signed-off-by: Jason Andryuk <jason.andryuk(a)amd.com> --- Stable backport for 6.6 .. 5.10. Direct cherry-pick needed context fixups, which are made here. This upstream commit was previously included in stable, but with the pre-req of b464b461d27d ("x86/pvh: Set phys_base when calling xen_prepare_pvh()"). Both were subsequently reverted as b464b461d27d caused regressions. This backport, e8fbc0d9cab6, in isolation is correct. This fixes a regression introduced by the backport of upstream commit b4845bb6383821a9516ce30af3a27dc873e37fd4 ("x86/xen: add central hypercall functions") b4845bb63838 adds a comparison between rip-relative xen_hypercall_amd() and kernel virtual address of xen_hypercall_amd() to determine whether to use the AMD or Intel variant. When running from the identity mapped address, the comparison always fail. The leads to calling xen_hypercall_intel(), even on AMD processors, which faults and halts boot. This affects PVH dom0 - domU doesn't seem to be affected. This patch performs the rip-relative mapping from the kernel virtual mapping, so the values can be properly compared. --- arch/x86/platform/pvh/head.S | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/x86/platform/pvh/head.S b/arch/x86/platform/pvh/head.S index c4365a05ab83..fc46b4dfbd74 100644 --- a/arch/x86/platform/pvh/head.S +++ b/arch/x86/platform/pvh/head.S @@ -100,7 +100,12 @@ SYM_CODE_START_LOCAL(pvh_start_xen) xor %edx, %edx wrmsr - call xen_prepare_pvh + /* Call xen_prepare_pvh() via the kernel virtual mapping */ + leaq xen_prepare_pvh(%rip), %rax + subq phys_base(%rip), %rax + addq $__START_KERNEL_map, %rax + ANNOTATE_RETPOLINE_SAFE + call *%rax /* startup_64 expects boot_params in %rsi. */ mov $_pa(pvh_bootparams), %rsi -- 2.49.0

[PATCH] staging: axis-fifo: Correct handling of tx_fifo_depth for size validation

by Gabriel Shahrouzi

Remove erroneous subtraction of 4 from the total FIFO depth read from device tree. The stored depth is for checking against total capacity, not initial vacancy. This prevented writes near the FIFO's full size. The check performed just before data transfer, which uses live reads of the TDFV register to determine current vacancy, correctly handles the initial Depth - 4 hardware state and subsequent FIFO fullness.

Hi stable mantainers, [note I'm CC'ing here Guillaume, Yu and Christoph] In Debian we were affected for a while by https://bugs.debian.org/1086175 which we found to be reported by Guillaume as https://lore.kernel.org/all/Z7Y0SURoA8xwg7vn@bender.morinfr.org/ . The issue went in fact back to 6.0. The fix was applied upstream and then backported to 6.14.2 already. Can you backport it please as well down to the other stable series, at least back to 6.12.y it goes with applying (and unless I miss something fixes the issue, we cherry-picked the commit for Debian trixie and our 6.12.y kernel in advance already). For going back to 6.1.y it seems it won't apply cleanly, You, Christoph might you be available to look into it to make this possible? Regards, Salvatore

[PATCH v2] iio: adc: Include valid channel for channel selection

by Gabriel Shahrouzi

According to the datasheet on page 9 under the channel selection table, all devices (AD7816/7/8) are able to use the channel marked as 7. This channel is used for diagnostic purposes by routing the internal 1.23V bandgap source through the MUX to the input of the ADC. Replace checking for string equality with checking for the same chip ID to reduce time complexity. Group invalid channels for all devices together because they are processed the same way.

[PATCH v3 0/4] J722S: Disable WIZ0 and WIZ1 in SoC file

by Siddharth Vadapalli

Hello, This series disables the "serdes_wiz0" and "serdes_wiz1" device-tree nodes in the J722S SoC file and enables them in the board files where they are required along with "serdes0" and "serdes1". There are two reasons behind this change: 1. To follow the existing convention of disabling nodes in the SoC file and enabling them in the board file as required. 2. To address situations where a board file hasn't explicitly disabled "serdes_wiz0" and "serdes_wiz1" (example: am67a-beagley-ai.dts) as a result of which booting the board displays the following errors: wiz bus@f0000:phy@f000000: probe with driver wiz failed with error -12 ... wiz bus@f0000:phy@f010000: probe with driver wiz failed with error -12 Additionally, another series for DT cleanup at: https://lore.kernel.org/r/20250412052712.927626-1-s-vadapalli@ti.com/ has been squashed into this series as patches 3 and 4.

[for-linus][PATCH 6/7] tracing: Fix filter string testing

From: Steven Rostedt <rostedt(a)goodmis.org> The filter string testing uses strncpy_from_kernel/user_nofault() to retrieve the string to test the filter against.

Implement the settling cycles encoding as specified in the AD5933 datasheet, Table 13 ("Number of Settling Times Cycles Register").

[PATCH] x86/mm: fix _pgd_alloc() for Xen PV mode

by Juergen Gross

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 using a variable holding the PGD allocation order in case CONFIG_MITIGATION_PAGE_TABLE_ISOLATION is set.

[PATCH AUTOSEL 5.10 8/8] fbdev: omapfb: Add 'plane' value check

by Sasha Levin

From: Leonid Arapov <arapovl839(a)gmail.com> [ Upstream commit 3e411827f31db7f938a30a3c7a7599839401ec30 ] Function dispc_ovl_setup is not intended to work with the value OMAP_DSS_WB of the enum parameter plane. The value of this parameter is initialized in dss_init_overlays and in the current state of the code it cannot take this value so it's not a real problem. For the purposes of defensive coding it wouldn't be superfluous to check the parameter value, because some functions down the call stack process this value correctly and some not. For example, in dispc_ovl_setup_global_alpha it may lead to buffer overflow. Add check for this value. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

[PATCH AUTOSEL 6.6 01/26] wifi: ath12k: Fix invalid entry fetch in ath12k_dp_mon_srng_process

by Sasha Levin

From: P Praneesh <quic_ppranees(a)quicinc.com> [ Upstream commit 63fdc4509bcf483e79548de6bc08bf3c8e504bb3 ] Currently, ath12k_dp_mon_srng_process uses ath12k_hal_srng_src_get_next_entry to fetch the next entry from the destination ring. This is incorrect because ath12k_hal_srng_src_get_next_entry is intended for source rings, not destination rings. This leads to invalid entry fetches, causing potential data corruption or crashes due to accessing incorrect memory locations. This happens because the source ring and destination ring have different handling mechanisms and using the wrong function results in incorrect pointer arithmetic and ring management. To fix this issue, replace the call to ath12k_hal_srng_src_get_next_entry with ath12k_hal_srng_dst_get_next_entry in ath12k_dp_mon_srng_process. This ensures that the correct function is used for fetching entries from the destination ring, preventing invalid memory accesses.

[PATCH AUTOSEL 5.10 01/15] page_pool: avoid infinite loop to schedule delayed worker

by Sasha Levin

From: Jason Xing <kerneljasonxing(a)gmail.com> [ Upstream commit 43130d02baa137033c25297aaae95fd0edc41654 ] We noticed the kworker in page_pool_release_retry() was waken up repeatedly and infinitely in production because of the buggy driver causing the inflight less than 0 and warning us in page_pool_inflight()[1]. Since the inflight value goes negative, it means we should not expect the whole page_pool to get back to work normally.

[PATCH v3] iio: adc: Correct conditional logic for store mode

by Gabriel Shahrouzi

The mode setting logic in ad7816_store_mode was reversed due to incorrect handling of the strcmp return value. strcmp returns 0 on match, so the `if (strcmp(buf, "full"))` block executed when the input was not "full". This resulted in "full" setting the mode to AD7816_PD (power-down) and other inputs setting it to AD7816_FULL. Fix this by checking it against 0 to correctly check for "full" and "power-down", mapping them to AD7816_FULL and AD7816_PD respectively.

[PATCH 5.15/5.10 1/2] blk-cgroup: support to track if policy is online

by bin.lan.cn＠windriver.com

From: Yu Kuai <yukuai3(a)huawei.com> [ Upstream commit dfd6200a095440b663099d8d42f1efb0175a1ce3 ] A new field 'online' is added to blkg_policy_data to fix following 2 problem: 1) In blkcg_activate_policy(), if pd_alloc_fn() with 'GFP_NOWAIT' failed, 'queue_lock' will be dropped and pd_alloc_fn() will try again without 'GFP_NOWAIT'. In the meantime, remove cgroup can race with it, and pd_offline_fn() will be called without pd_init_fn() and pd_online_fn(). This way null-ptr-deference can be triggered. 2) In order to synchronize pd_free_fn() from blkg_free_workfn() and blkcg_deactivate_policy(), 'list_del_init(&blkg->q_node)' will be delayed to blkg_free_workfn(), hence pd_offline_fn() can be called first in blkg_destroy(), and then blkcg_deactivate_policy() will call it again, we must prevent it. The new field 'online' will be set after pd_online_fn() and will be cleared after pd_offline_fn(), in the meantime pd_offline_fn() will only be called if 'online' is set.

However, there is no explicit check to verify this assumption. If another device within the same group has been attached, the replace operation might succeed, but the input device itself may not have been attached yet. As a result, the input device might not be tracked in the igroup->device_list, and its reserved IOVA might not be added. Despite this, the caller might incorrectly assume that the device has been successfully replaced, which could lead to unexpected behavior or errors. To address this issue, add a check to ensure that the input device has been attached before proceeding with the replace operation. This check will help maintain the integrity of the device tracking system and prevent potential issues arising from incorrect assumptions about the device's attachment status.

[PATCH 6.1.y 1/2] blk-cgroup: support to track if policy is online

by bin.lan.cn＠windriver.com

From: Yu Kuai <yukuai3(a)huawei.com> [ Upstream commit dfd6200a095440b663099d8d42f1efb0175a1ce3 ] A new field 'online' is added to blkg_policy_data to fix following 2 problem: 1) In blkcg_activate_policy(), if pd_alloc_fn() with 'GFP_NOWAIT' failed, 'queue_lock' will be dropped and pd_alloc_fn() will try again without 'GFP_NOWAIT'. In the meantime, remove cgroup can race with it, and pd_offline_fn() will be called without pd_init_fn() and pd_online_fn(). This way null-ptr-deference can be triggered. 2) In order to synchronize pd_free_fn() from blkg_free_workfn() and blkcg_deactivate_policy(), 'list_del_init(&blkg->q_node)' will be delayed to blkg_free_workfn(), hence pd_offline_fn() can be called first in blkg_destroy(), and then blkcg_deactivate_policy() will call it again, we must prevent it. The new field 'online' will be set after pd_online_fn() and will be cleared after pd_offline_fn(), in the meantime pd_offline_fn() will only be called if 'online' is set.

[PATCH] iio: adc: Revoke valid channel for error path

by Gabriel Shahrouzi

According to the datasheet on page 9 under the channel selection table, all devices (AD7816/7/8) are able to use the channel marked as 7. This channel is used for diagnostic purposes by routing the internal 1.23V bandgap source through the MUX to the input of the ADC. Replace checking for string equality with checking for the same chip ID to reduce time complexity. Group invalid channels for all devices together because they are processed the same way.

However, when X86_FEATURE_ZEN1 was introduced, the condition to detect unaffected processors was incorrectly changed in a way that the IRPerfEn bit gets set only for unaffected Zen 1 processors. Ensure that HWCR[IRPerfEn] is set for all unaffected processors. This includes a subset of Zen 1 (Family 17h Models 30h and above) and all later processors. Also clear X86_FEATURE_IRPERF on affected processors so that the IRPerfCount register is not used by other entities like the MSR PMU driver.

[tip: x86/urgent] x86/boot/sev: Avoid shared GHCB page for early memory acceptance

When executing in the context of the EFI boot services, the page tables are owned by the firmware, and this manipulation is not possible. So switch to a different API for accepting memory in SEV-SNP guests, one which is actually supported at the point during boot where the EFI stub may need to accept memory, but the SEV-SNP init code has not executed yet. For simplicity, also switch the memory acceptance carried out by the decompressor when not booting via EFI - this only involves the allocation for the decompressed kernel, and is generally only called after kexec, as normal boot will jump straight into the kernel from the EFI stub.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From aa9f168d55dc47c0de564f7dfe0e90467c9fee71 Mon Sep 17 00:00:00 2001 From: Niklas Schnelle <schnelle(a)linux.ibm.com> Date: Wed, 26 Feb 2025 13:07:47 +0100 Subject: [PATCH] s390/pci: Support mmap() of PCI resources except for ISM devices So far s390 does not allow mmap() of PCI resources to user-space via the usual mechanisms, though it does use it for RDMA. For the PCI sysfs resource files and /proc/bus/pci it defines neither HAVE_PCI_MMAP nor ARCH_GENERIC_PCI_MMAP_RESOURCE. For vfio-pci s390 previously relied on disabled VFIO_PCI_MMAP and now relies on setting pdev->non_mappable_bars for all devices. This is partly because access to mapped PCI resources from user-space requires special PCI load/store memory-I/O (MIO) instructions, or the special MMIO syscalls when these are not available. Still, such access is possible and useful not just for RDMA, in fact not being able to mmap() PCI resources has previously caused extra work when testing devices. One thing that doesn't work with PCI resources mapped to user-space though is the s390 specific virtual ISM device. Not only because the BAR size of 256 TiB prevents mapping the whole BAR but also because access requires use of the legacy PCI instructions which are not accessible to user-space on systems with the newer MIO PCI instructions. Now with the pdev->non_mappable_bars flag ISM can be excluded from mapping its resources while making this functionality available for all other PCI devices. To this end introduce a minimal implementation of PCI_QUIRKS and use that to set pdev->non_mappable_bars for ISM devices only. Then also set ARCH_GENERIC_PCI_MMAP_RESOURCE to take advantage of the generic implementation of pci_mmap_resource_range() enabling only the newer sysfs mmap() interface. This follows the recommendation in Documentation/PCI/sysfs-pci.rst.

[tip: x86/urgent] x86/boot/sev: Avoid shared GHCB page for early memory acceptance

by tip-bot2 for Ard Biesheuvel

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: a718833cb4567fffec26bc62633081b27fa5f90a Gitweb: https://git.kernel.org/tip/a718833cb4567fffec26bc62633081b27fa5f90a Author: Ard Biesheuvel <ardb(a)kernel.org> AuthorDate: Thu, 17 Apr 2025 22:21:21 +02:00 Committer: Ingo Molnar <mingo(a)kernel.org> CommitterDate: Fri, 18 Apr 2025 09:53:32 +02:00 x86/boot/sev: Avoid shared GHCB page for early memory acceptance Communicating with the hypervisor using the shared GHCB page requires clearing the C bit in the mapping of that page. When executing in the context of the EFI boot services, the page tables are owned by the firmware, and this manipulation is not possible. So switch to a different API for accepting memory in SEV-SNP guests, one which is actually supported at the point during boot where the EFI stub may need to accept memory, but the SEV-SNP init code has not executed yet. For simplicity, also switch the memory acceptance carried out by the decompressor when not booting via EFI - this only involves the allocation for the decompressed kernel, and is generally only called after kexec, as normal boot will jump straight into the kernel from the EFI stub.

[PATCH 1/1] usb: gadget: tegra-xudc: ACK ST_RC after clearing CTRL_RUN

by Wayne Chang

We identified a bug where the ST_RC bit in the status register was not being acknowledged after clearing the CTRL_RUN bit in the control register. This could lead to unexpected behavior in the USB gadget drivers. This patch resolves the issue by adding the necessary code to explicitly acknowledge ST_RC after clearing CTRL_RUN based on the programming sequence, ensuring proper state transition.

[PATCH] iommu: intel: apply quirk_iommu_igfx for 8086:0044 (QM57/QS57)

by Mingcong Bai

On the Lenovo ThinkPad X201, when Intel VT-d is enabled in the BIOS, the kernel boots with errors related to DMAR, the graphical interface appeared quite choppy, and the system resets erratically within a minute after it booted: DMAR: DRHD: handling fault status reg 3 DMAR: [DMA Write NO_PASID] Request device [00:02.0] fault addr 0xb97ff000 [fault reason 0x05] PTE Write access is not set Upon comparing boot logs with VT-d on/off, I found that the Intel Calpella quirk (`quirk_calpella_no_shadow_gtt()') correctly applied the igfx IOMMU disable/quirk correctly: pci 0000:00:00.0: DMAR: BIOS has allocated no shadow GTT; disabling IOMMU for graphics Whereas with VT-d on, it went into the "else" branch, which then triggered the DMAR handling fault above: ... else if (!disable_igfx_iommu) { /* we have to ensure the gfx device is idle before we flush */ pci_info(dev, "Disabling batched IOTLB flush on Ironlake\n"); iommu_set_dma_strict(); } Now, this is not exactly scientific, but moving 0x0044 to quirk_iommu_igfx seems to have fixed the aforementioned issue. Running a few `git blame' runs on the function, I have found that the quirk was originally introduced as a fix specific to ThinkPad X201: commit 9eecabcb9a92 ("intel-iommu: Abort IOMMU setup for igfx if BIOS gave no shadow GTT space") Which was later revised twice to the "else" branch we saw above: - 2011: commit 6fbcfb3e467a ("intel-iommu: Workaround IOTLB hang on Ironlake GPU") - 2024: commit ba00196ca41c ("iommu/vt-d: Decouple igfx_off from graphic identity mapping") I'm uncertain whether further testings on this particular laptops were done in 2011 and (honestly I'm not sure) 2024, but I would be happy to do some distro-specific testing if that's what would be required to verify this patch. P.S., I also see IDs 0x0040, 0x0062, and 0x006a listed under the same `quirk_calpella_no_shadow_gtt()' quirk, but I'm not sure how similar these chipsets are (if they share the same issue with VT-d or even, indeed, if this issue is specific to a bug in the Lenovo BIOS). With regards to 0x0062, it seems to be a Centrino wireless card, but not a chipset? I have also listed a couple (distro and kernel) bug reports below as references (some of them are from 7-8 years ago!), as they seem to be similar issue found on different Westmere/Ironlake, Haswell, and Broadwell hardware setups.

[PATCH] drm/xe/gsc: do not flush the GSC worker from the reset path

by Daniele Ceraolo Spurio

The workqueue used for the reset worker is marked as WQ_MEM_RECLAIM, while the GSC one isn't (and can't be as we need to do memory allocations in the gsc worker). Therefore, we can't flush the latter from the former. The reason why we had such a flush was to avoid interrupting either the GSC FW load or in progress GSC proxy operations. GSC proxy operations fall into 2 categories: 1) GSC proxy init: this only happen once immediately after GSC FW laod and does not support being interrupted. The only way to recover from an interruption of the proxy init is to do an FLR and re-load the GSC. 2) GSC proxy request: this can happen in response to a request that the driver sends to the GSC. If this is interrupted, the GSC FW will timeout and the driver request will be failed, but overall the GSC will keep working fine. Flushing the work allowed us to avoid interruption in both cases (unless the hang came from the GSC engine itself, in which case we're toast anyway). However, a failure on a proxy request is tolerable if we're in a scenario where we're triggering a GT reset (i.e., something is already gone pretty wrong), so what we really need to avoid is interrupting the init flow, which we can do by polling on the register that reports when the proxy init is complete (as that ensure us that all the load and init operations have been completed).

The following patch series enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support. This patch (of 3): Memory leaks occurred when removing sysfs attributes for weighted interleave. Improper kobject deallocation led to unreleased memory when initialization failed or when nodes were removed. This patch resolves the issue by replacing unnecessary `kfree()` calls with proper `kobject_del()` and `kobject_put()` sequences, ensuring correct teardown and preventing memory leaks. By explicitly calling `kobject_del()` before `kobject_put()`, the release function is now invoked safely, and internal sysfs state is correctly cleaned up. This guarantees that the memory associated with the kobject is fully released and avoids resource leaks, thereby improving system stability. Additionally, sysfs_remove_file() is no longer called from the release function to avoid accessing invalid sysfs state after kobject_del(). All attribute removals are now done before kobject_del(), preventing WARN_ON() in kernfs and ensuring safe and consistent cleanup of sysfs entries.

[PATCH v4] x86/boot/sev: Avoid shared GHCB page for early memory acceptance

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> Communicating with the hypervisor using the shared GHCB page requires clearing the C bit in the mapping of that page. When executing in the context of the EFI boot services, the page tables are owned by the firmware, and this manipulation is not possible. So switch to a different API for accepting memory in SEV-SNP guests, one which is actually supported at the point during boot where the EFI stub may need to accept memory, but the SEV-SNP init code has not executed yet. For simplicity, also switch the memory acceptance carried out by the decompressor when not booting via EFI - this only involves the allocation for the decompressed kernel, and is generally only called after kexec, as normal boot will jump straight into the kernel from the EFI stub.

Please apply 8b55f8818900 to 6.12 through 6.1

by Nathan Chancellor

Hi Greg and Sasha, Please consider applying commit 8b55f8818900 ("media: mediatek: vcodec: mark vdec_vp9_slice_map_counts_eob_coef noinline") to 6.12, 6.6, and 6.1, as it avoids a warning that breaks arm64 allmodconfig for certain clang versions due to -Werror. It applies cleanly to the first two trees for me and I have attached a backport for 6.1 due to a file location change. Please let me know if there are any issues. Cheers, Nathan

[PATCH 1/1] selftests/pcie_bwctrl: Fix test progs list

by Ilpo Järvinen

The commit df6f8c4d72ae ("selftests/pcie_bwctrl: Add 'set_pcie_speed.sh' to TEST_PROGS") added set_pcie_speed.sh into TEST_PROGS but that script is a helper that is only being called by set_pcie_cooling_state.sh, not a test case itself. When set_pcie_speed.sh is in TEST_PROGS, selftest harness will execute also it leading to bwctrl selftest errors: # selftests: pcie_bwctrl: set_pcie_speed.sh # cat: /cur_state: No such file or directory not ok 2 selftests: pcie_bwctrl: set_pcie_speed.sh # exit=1 Place set_pcie_speed.sh into TEST_FILES instead to have it included into installed test files but not execute it from the test harness.

[PATCH RESEND] dmaengine: ti: k3-udma: Use cap_mask directly from dma_device structure instead of a local copy

by Yemike Abhilash Chandra

Currently, a local dma_cap_mask_t variable is used to store device cap_mask within udma_of_xlate(). However, the DMA_PRIVATE flag in the device cap_mask can get cleared when the last channel is released. This can happen right after storing the cap_mask locally in udma_of_xlate(), and subsequent dma_request_channel() can fail due to mismatch in the cap_mask. Fix this by removing the local dma_cap_mask_t variable and directly using the one from the dma_device structure.

However, there is no explicit check to verify this assumption. If another device within the same group has been attached, the replace operation might succeed, but the input device itself may not have been attached yet. As a result, the input device might not be tracked in the igroup->device_list, and its reserved IOVA might not be added. Despite this, the caller might incorrectly assume that the device has been successfully replaced, which could lead to unexpected behavior or errors. To address this issue, add a check to ensure that the input device has been attached before proceeding with the replace operation. This check will help maintain the integrity of the device tracking system and prevent potential issues arising from incorrect assumptions about the device's attachment status.

[PATCH] iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihid

by Pavel Paklov

There is a string parsing logic error which can lead to an overflow of hid or uid buffers. Comparing ACPIID_LEN against a total string length doesn't take into account the lengths of individual hid and uid buffers so the check is insufficient in some cases. For example if the length of hid string is 4 and the length of the uid string is 260, the length of str will be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer which size is 256. The same applies to the hid string with length 13 and uid string with length 250. Check the length of hid and uid strings separately to prevent buffer overflow. Found by Linux Verification Center (linuxtesting.org) with SVACE.

6.14.y regression in ath11k

by Mario Limonciello

Hello, Matt Schwartz (cc) found a regression in 6.14.2 that the Steam Deck OLED took 45s to find a network after suspend/resume waiting for a timeout. This was a regression from 6.14.1. The regression happened because: commit 933ab187e679 ("wifi: ath11k: update channel list in reg notifier instead reg worker") was backported to 6.14.y without the other commit in the series: commit 02aae8e2f957 ("wifi: ath11k: update channel list in worker when wait flag is set") Backporting commit 02aae8e2f957 ("wifi: ath11k: update channel list in worker when wait flag is set") to 6.14.2 fixes the regression. Can you please take this commit back to stable too? Thanks!

This resolves an issue where the PHY may not properly initialize during subsequent power-on cycles. Power-on will deassert the reset at the appropriate time after tuning the PHY parameters. During suspend/resume cycles, we observed that the PHY PLL failed to lock during resume when the CPU temperature increased from 65C to 75C. The observed errors were: phy phy-32f00000.pcie-phy.3: phy poweron failed --> -110 imx6q-pcie 33800000.pcie: waiting for PHY ready timeout! imx6q-pcie 33800000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x80 returns -110 imx6q-pcie 33800000.pcie: PM: failed to resume noirq: error -110 This resulted in a complete CPU freeze, which is resolved by ensuring the PHY is in reset during power-on, thus preventing PHY PLL failures.

The minimum value for it is 20 Celsius, which is what is configured when there's no lower thermal trip (ie the thermal core passes -INT_MAX as low trip temperature). However, when the temperature gets that low and fluctuates around that value it causes an interrupt storm. Prevent that interrupt storm by not enabling the low offset interrupt if the low threshold is the minimum one.

From the kernel perspective, this configuration is harmful because: * The stage 3 interrupt that gets triggered when the threshold is crossed is not handled in any way by the IRQ handler, it just gets cleared. Besides, the temperature used for stage 3 comes from the sensors, and the critical thermal trip points described in the Devicetree will already cause a shutdown when crossed (at a lower temperature, of 100 Celsius, for all SoCs currently using this driver). * The only effect of crossing the stage 3 threshold that has been observed is that it causes the machine to no longer be able to enter suspend. Even if that was a result of a momentary glitch in the temperature reading of a sensor (as has been observed on the MT8192-based Chromebooks). For those reasons, disable the Stage 3 thermal threshold configuration.

[tip: perf/core] perf/x86/intel: Don't clear perf metrics overflow bit unconditionally

by tip-bot2 for Dapeng Mi

[tip: perf/core] perf/x86/intel: Allow to update user space GPRs from PEBS records

by tip-bot2 for Dapeng Mi

The following commit has been merged into the perf/core branch of tip: Commit-ID: 71dcc11c2cd9e434c34a63154ecadca21c135ddd Gitweb: https://git.kernel.org/tip/71dcc11c2cd9e434c34a63154ecadca21c135ddd Author: Dapeng Mi <dapeng1.mi(a)linux.intel.com> AuthorDate: Tue, 15 Apr 2025 10:41:35 Committer: Ingo Molnar <mingo(a)kernel.org> CommitterDate: Thu, 17 Apr 2025 14:19:38 +02:00 perf/x86/intel: Allow to update user space GPRs from PEBS records Currently when a user samples user space GPRs (--user-regs option) with PEBS, the user space GPRs actually always come from software PMI instead of from PEBS hardware. This leads to the sampled GPRs to possibly be inaccurate for single PEBS record case because of the skid between counter overflow and GPRs sampling on PMI. For the large PEBS case, it is even worse. If user sets the exclude_kernel attribute, large PEBS would be used to sample user space GPRs, but since PEBS GPRs group is not really enabled, it leads to all samples in the large PEBS record to share the same piece of user space GPRs, like this reproducer shows: $ perf record -e branches:pu --user-regs=ip,ax -c 100000 ./foo $ perf report -D | grep "AX" .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead .... AX 0x000000003a0d4ead ....

If the PEBS sampled GPRs is not user space GPRs (single PEBS record case), perf_sample_regs_user() modifies them to user space GPRs.

In particular, before commit 9cb28da54643 ("mm/gup: handle hugetlb in the generic follow_page_mask code"), GUP(FOLL_SPLIT_PMD) would just have returned a page. In particular, hugetlb folios that are not PMD-sized would never have been prone to FOLL_SPLIT_PMD. hugetlb folios can be anonymous, and page_make_device_exclusive_one() is not really prepared for handling them at all.

Add a field for DAMOS scheme object that can be used by the underlying ops to know what was the last entity that the scheme's action has applied. The core layer unsets the field when each DAMOS-regions-walk is done for the given scheme. And update 'paddr' ops to use the infrastructure to avoid the problem.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 0bb2f7a1ad1f11d861f58e5ee5051c8974ff9569 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima <kuniyu(a)amazon.com> Date: Mon, 7 Apr 2025 09:33:11 -0700 Subject: [PATCH] net: Fix null-ptr-deref by sock_lock_init_class_and_name() and rmmod. When I ran the repro [0] and waited a few seconds, I observed two LOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1] Reproduction Steps: 1) Mount CIFS 2) Add an iptables rule to drop incoming FIN packets for CIFS 3) Unmount CIFS 4) Unload the CIFS module 5) Remove the iptables rule At step 3), the CIFS module calls sock_release() for the underlying TCP socket, and it returns quickly. However, the socket remains in FIN_WAIT_1 because incoming FIN packets are dropped. At this point, the module's refcnt is 0 while the socket is still alive, so the following rmmod command succeeds. # ss -tan State Recv-Q Send-Q Local Address:Port Peer Address:Port FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445 # lsmod | grep cifs cifs 1159168 0 This highlights a discrepancy between the lifetime of the CIFS module and the underlying TCP socket. Even after CIFS calls sock_release() and it returns, the TCP socket does not die immediately in order to close the connection gracefully. While this is generally fine, it causes an issue with LOCKDEP because CIFS assigns a different lock class to the TCP socket's sk->sk_lock using sock_lock_init_class_and_name(). Once an incoming packet is processed for the socket or a timer fires, sk->sk_lock is acquired. Then, LOCKDEP checks the lock context in check_wait_context(), where hlock_class() is called to retrieve the lock class. However, since the module has already been unloaded, hlock_class() logs a warning and returns NULL, triggering the null-ptr-deref. If LOCKDEP is enabled, we must ensure that a module calling sock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloaded while such a socket is still alive to prevent this issue. Let's hold the module reference in sock_lock_init_class_and_name() and release it when the socket is freed in sk_prot_free(). Note that sock_lock_init() clears sk->sk_owner for svc_create_socket() that calls sock_lock_init_class_and_name() for a listening socket, which clones a socket by sk_clone_lock() without GFP_ZERO.

When I ran the repro [0] and waited a few seconds, I observed two LOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1] Reproduction Steps: 1) Mount CIFS 2) Add an iptables rule to drop incoming FIN packets for CIFS 3) Unmount CIFS 4) Unload the CIFS module 5) Remove the iptables rule At step 3), the CIFS module calls sock_release() for the underlying TCP socket, and it returns quickly. However, the socket remains in FIN_WAIT_1 because incoming FIN packets are dropped. At this point, the module's refcnt is 0 while the socket is still alive, so the following rmmod command succeeds. # ss -tan State Recv-Q Send-Q Local Address:Port Peer Address:Port FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445 # lsmod | grep cifs cifs 1159168 0 This highlights a discrepancy between the lifetime of the CIFS module and the underlying TCP socket. Even after CIFS calls sock_release() and it returns, the TCP socket does not die immediately in order to close the connection gracefully. While this is generally fine, it causes an issue with LOCKDEP because CIFS assigns a different lock class to the TCP socket's sk->sk_lock using sock_lock_init_class_and_name(). Once an incoming packet is processed for the socket or a timer fires, sk->sk_lock is acquired. Then, LOCKDEP checks the lock context in check_wait_context(), where hlock_class() is called to retrieve the lock class. However, since the module has already been unloaded, hlock_class() logs a warning and returns NULL, triggering the null-ptr-deref. If LOCKDEP is enabled, we must ensure that a module calling sock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloaded while such a socket is still alive to prevent this issue. Let's hold the module reference in sock_lock_init_class_and_name() and release it when the socket is freed in sk_prot_free(). Note that sock_lock_init() clears sk->sk_owner for svc_create_socket() that calls sock_lock_init_class_and_name() for a listening socket, which clones a socket by sk_clone_lock() without GFP_ZERO.

When I ran the repro [0] and waited a few seconds, I observed two LOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1] Reproduction Steps: 1) Mount CIFS 2) Add an iptables rule to drop incoming FIN packets for CIFS 3) Unmount CIFS 4) Unload the CIFS module 5) Remove the iptables rule At step 3), the CIFS module calls sock_release() for the underlying TCP socket, and it returns quickly. However, the socket remains in FIN_WAIT_1 because incoming FIN packets are dropped. At this point, the module's refcnt is 0 while the socket is still alive, so the following rmmod command succeeds. # ss -tan State Recv-Q Send-Q Local Address:Port Peer Address:Port FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445 # lsmod | grep cifs cifs 1159168 0 This highlights a discrepancy between the lifetime of the CIFS module and the underlying TCP socket. Even after CIFS calls sock_release() and it returns, the TCP socket does not die immediately in order to close the connection gracefully. While this is generally fine, it causes an issue with LOCKDEP because CIFS assigns a different lock class to the TCP socket's sk->sk_lock using sock_lock_init_class_and_name(). Once an incoming packet is processed for the socket or a timer fires, sk->sk_lock is acquired. Then, LOCKDEP checks the lock context in check_wait_context(), where hlock_class() is called to retrieve the lock class. However, since the module has already been unloaded, hlock_class() logs a warning and returns NULL, triggering the null-ptr-deref. If LOCKDEP is enabled, we must ensure that a module calling sock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloaded while such a socket is still alive to prevent this issue. Let's hold the module reference in sock_lock_init_class_and_name() and release it when the socket is freed in sk_prot_free(). Note that sock_lock_init() clears sk->sk_owner for svc_create_socket() that calls sock_lock_init_class_and_name() for a listening socket, which clones a socket by sk_clone_lock() without GFP_ZERO.

When I ran the repro [0] and waited a few seconds, I observed two LOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1] Reproduction Steps: 1) Mount CIFS 2) Add an iptables rule to drop incoming FIN packets for CIFS 3) Unmount CIFS 4) Unload the CIFS module 5) Remove the iptables rule At step 3), the CIFS module calls sock_release() for the underlying TCP socket, and it returns quickly. However, the socket remains in FIN_WAIT_1 because incoming FIN packets are dropped. At this point, the module's refcnt is 0 while the socket is still alive, so the following rmmod command succeeds. # ss -tan State Recv-Q Send-Q Local Address:Port Peer Address:Port FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445 # lsmod | grep cifs cifs 1159168 0 This highlights a discrepancy between the lifetime of the CIFS module and the underlying TCP socket. Even after CIFS calls sock_release() and it returns, the TCP socket does not die immediately in order to close the connection gracefully. While this is generally fine, it causes an issue with LOCKDEP because CIFS assigns a different lock class to the TCP socket's sk->sk_lock using sock_lock_init_class_and_name(). Once an incoming packet is processed for the socket or a timer fires, sk->sk_lock is acquired. Then, LOCKDEP checks the lock context in check_wait_context(), where hlock_class() is called to retrieve the lock class. However, since the module has already been unloaded, hlock_class() logs a warning and returns NULL, triggering the null-ptr-deref. If LOCKDEP is enabled, we must ensure that a module calling sock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloaded while such a socket is still alive to prevent this issue. Let's hold the module reference in sock_lock_init_class_and_name() and release it when the socket is freed in sk_prot_free(). Note that sock_lock_init() clears sk->sk_owner for svc_create_socket() that calls sock_lock_init_class_and_name() for a listening socket, which clones a socket by sk_clone_lock() without GFP_ZERO.

However, there is no explicit check to verify this assumption. If another device within the same group has been attached, the replace operation might succeed, but the input device itself may not have been attached yet. As a result, the input device might not be tracked in the igroup->device_list, and its reserved IOVA might not be added. Despite this, the caller might incorrectly assume that the device has been successfully replaced, which could lead to unexpected behavior or errors. To address this issue, add a check to ensure that the input device has been attached before proceeding with the replace operation. This check will help maintain the integrity of the device tracking system and prevent potential issues arising from incorrect assumptions about the device's attachment status.

When we have compressed writes this assertion may fail because delayed iputs may have been added to the list after we last ran delayed iputs. This happens like this: 1) We have a compressed write bio executing; 2) We enter close_ctree() and flush the fs_info->endio_write_workers queue which is the queue used for running ordered extent completion; 3) The compressed write bio finishes and enters btrfs_finish_compressed_write_work(), where it calls btrfs_finish_ordered_extent() which in turn calls btrfs_queue_ordered_fn(), which queues a work item in the fs_info->endio_write_workers queue that we have flushed before; 4) At close_ctree() we proceed, run all existing delayed iputs and call btrfs_commit_super() (which also runs delayed iputs), but before we run the following assertion below: ASSERT(list_empty(&fs_info->delayed_iputs)) A delayed iput is added by the step below... 5) The ordered extent completion job queued in step 3 runs and results in creating a delayed iput when dropping the last reference of the ordered extent (a call to btrfs_put_ordered_extent() made from btrfs_finish_one_ordered()); 6) At this point the delayed iputs list is not empty, so the assertion at close_ctree() fails. Fix this by flushing the fs_info->compressed_write_workers queue at close_ctree() before flushing the fs_info->endio_write_workers queue, respecting the queue dependency as the later is responsible for the execution of ordered extent completion.

[PATCH v3] platform/x86/intel-uncore-freq: Fix missing uncore sysfs during CPU hotplug

by shouyeliu

From: Shouye Liu <shouyeliu(a)tencent.com> In certain situations, the sysfs for uncore may not be present when all CPUs in a package are offlined and then brought back online after boot. This issue can occur if there is an error in adding the sysfs entry due to a memory allocation failure. Retrying to bring the CPUs online will not resolve the issue, as the uncore_cpu_mask is already set for the package before the failure condition occurs. This issue does not occur if the failure happens during module initialization, as the module will fail to load in the event of any error.

[PATCH] platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles

by Mario Limonciello

From: Mario Limonciello <mario.limonciello(a)amd.com> When an APU exits HW sleep with no active wake sources the Linux kernel will rapidly assert that the APU can enter back into HW sleep. This happens in a few ms. Contrasting this to Windows, Windows can take 10s of seconds to enter back into the resiliency phase for Modern Standby. For some situations this can be problematic because it can cause leakage from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical design guide specifications. On some designs this will trip the over voltage protection feature (OVP) of the voltage regulator module, but it could cause APU damage as well. To prevent this risk, add an explicit sleep call so that future attempts to enter into HW sleep will have enough time to settle. This will occur while the screen is dark and only on cases that the APU should enter HW sleep again, so it shouldn't be noticeable to any user.

In practice, this fixes the call to mmu_notifier_arch_invalidate_secondary_tlbs() in __flush_tlb_range_nosync() to use the correct range instead of an empty range with start=end. The empty range was (un)lucky as it results in taking the invalidate-all path that doesn't cause correctness issues, but can certainly result in suboptimal perf. This has been broken since commit 6bbd42e2df8f ("mmu_notifiers: call invalidate_range() when invalidating TLBs") when the call to the notifiers was added to __flush_tlb_range(). It predates the addition of the __flush_tlb_range_op() macro from commit 360839027a6e ("arm64: tlb: Refactor the core flush algorithm of __flush_tlb_range") that made the bug hard to spot.
