[PATCH stable 6.6 00/10] bpf: track changes_pkt_data property for global functions

by Shung-Hsi Yu

Fix the bypassing of invalid packet pointer check in 6.6 by backporting the entire "bpf: track changes_pkt_data property for global functions" series[1], along with the follow up, "bpf: fix NPE when computing changes_pkt_data of program w/o subprograms" series[2]; both from Eduard. I had ran the BPF selftests after backporting, confirmed that newly added BPF selftests passes, and that no new failure observed in BPF selftests (dummy_st_ops, ns_current_pid_tgid, test_bpf_ma, and test_bpffs are failing even without this patchset applied). See [3] for the full log. #50/1 changes_pkt_data_freplace/changes_pkt_data_with_changes_pkt_data:OK #50/2 changes_pkt_data_freplace/changes_pkt_data_with_does_not_change_pkt_data:OK #50/3 changes_pkt_data_freplace/does_not_change_pkt_data_with_changes_pkt_data:OK #50/4 changes_pkt_data_freplace/does_not_change_pkt_data_with_does_not_change_pkt_data:OK #50/5 changes_pkt_data_freplace/main_changes_with_changes_pkt_data:OK #50/6 changes_pkt_data_freplace/main_changes_with_does_not_change_pkt_data:OK #50/7 changes_pkt_data_freplace/main_does_not_change_with_changes_pkt_data:OK #50/8 changes_pkt_data_freplace/main_does_not_change_with_does_not_change_pkt_data:OK #395/57 verifier_sock/invalidate_pkt_pointers_from_global_func:OK #395/58 verifier_sock/invalidate_pkt_pointers_by_tail_call:OK 1: https://lore.kernel.org/all/20241210041100.1898468-1-eddyz87@gmail.com/ 2: https://lore.kernel.org/all/20241212070711.427443-1-eddyz87@gmail.com/ 3: https://github.com/shunghsiyu/libbpf/actions/runs/14747347842/job/413971041… Eduard Zingerman (10): bpf: add find_containing_subprog() utility function bpf: refactor bpf_helper_changes_pkt_data to use helper number 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 bpf: consider that tail calls invalidate packet pointers 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 + include/linux/filter.h | 2 +- kernel/bpf/core.c | 2 +- kernel/bpf/verifier.c | 81 +++++++++++-- net/core/filter.c | 63 +++++------ .../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 +++++++++ 10 files changed, 324 insertions(+), 46 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 v2 00/23] 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 in v2: - Added Changes to make sure all buffers are released in session close (bryna) - Added tracking for flush responses to fix a timing issue. - Added a handling to fix timing issue in reconfig - Splitted patch 06/20 in two patches (Bryan) - Added missing fixes tag (bryan) - Updated fluster report (Nicolas) - Link to v1: https://lore.kernel.org/r/20250408-iris-dec-hevc-vp9-v1-0-acd258778bd6@quic… 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@… This patch series depends on [1] & [2] [1] https://lore.kernel.org/linux-media/20250417-topic-sm8x50-iris-v10-v7-0-f02… [2] https://lore.kernel.org/linux-media/20250424-qcs8300_iris-v5-0-f118f505c300… 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 [3] [3]: 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 - 2 testcase failed due to CRC mismatch - RAP_A_docomo_6 - RAP_B_Bossen_2 - BUG reported: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4392 Analysis - First few frames in this discarded by firmware and are sent to driver with 0 filled length.

[REGRESSION][BISECTED][STABLE] MT7925: mDNS and IPv6 broken in kernel 6.14.3 and above

by fossben＠pm.me

Hello all, After upgrading to 6.14.3 on my PC with a MT7925 chip, I noticed that I could no longer ping *.local addresses provided by Avahi. In addition, I also noticed that I was not able to get a DHCP IPv6 address from my router, no matter how many times I rebooted the router or reconnected with NetworkManager. Reverting to 6.14.2 fixes both mDNS and IPv6 addresses immediately. Going back to 6.14.3 immediately breaks mDNS again, but the IPv6 address will stay there for a while before disappearing later, possibly because the DHCP lease expired? I am not sure exactly when it stops working. I've done a kernel bisect between 6.14.2 and 6.14.3 and found the offending commit that causes mDNS to fail: commit 80007d3f92fd018d0a052a706400e976b36e3c87 Author: Ming Yen Hsieh <mingyen.hsieh(a)mediatek.com> Date: Tue Mar 4 16:08:50 2025 -0800 wifi: mt76: mt7925: integrate *mlo_sta_cmd and *sta_cmd commit cb1353ef34735ec1e5d9efa1fe966f05ff1dc1e1 upstream.

Fixes: 86c051f2c418 ("wifi: mt76: mt7925: enabling MLO when the firmware supports it") drivers/net/wireless/mediatek/mt76/mt7925/mcu.c | 59 ++++------------------------------------------------------- 1 file changed, 4 insertions(+), 55 deletions(-) I do not know if this same commit is also causing the IPv6 issues as testing that requires quite a bit of time to reproduce. What I do know with certainty as of this moment is that it definitely breaks in kernel 6.14.3. I've attached my hardware info as well as dmesg logs from the last working kernel from the bisect and 6.14.4 which exhibits the issue. Please let me know if there's any other info you need. Thanks!

[PATCH v2 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 v5] Restrict devmem for confidential VMs

by Dan Williams

Changes since v3 [1] (note v4 was a partial re-roll, but more feedback came in requiring a v5): - Fix a kbuild robot report for a missing header include of cc_platform.h - Switch to selecting STRICT_DEVMEM and IOSTRICT_DEVMEM rather than "depends on". (Naveen) - Clarify the "SEPT violation" vs "crash" and other changelog fixups for devmem maintainers and other arch maintainers. (Dave) - Drop patch numbering since patch2 is a fix and has no dependencies on patch1 [1]: http://lore.kernel.org/174491711228.1395340.3647010925173796093.stgit@dwill… --- The original response to Nikolay's report of a "crash" (unhandled SEPT violation) triggered by /dev/mem access to private memory was "let's just turn off /dev/mem". After some machinations of x86_platform_ops to block a subset of problematic access, spelunking the history of devmem_is_allowed() returning "2" to enable some compatibility benefits while blocking access, and discovering that userspace depends buggy kernel behavior for mmap(2) of the first 1MB of memory on x86, the proposal has circled back to "disable /dev/mem". Require both STRICT_DEVMEM and IO_STRICT_DEVMEM for x86 confidential guests to close /dev/mem hole while still allowing for userspace mapping of PCI MMIO as long as the kernel and userspace are not mapping the range at the same time. The range_is_allowed() cleanup is not strictly necessary, but might as well close a 17 year-old "TODO".

[PATCH] ASoC: fsl: fsl_qmc_audio: Reset audio data pointers on TRIGGER_START event

by Herve Codina

On SNDRV_PCM_TRIGGER_START event, audio data pointers are not reset. This leads to wrong data buffer usage when multiple TRIGGER_START are received and ends to incorrect buffer usage between the user-space and the driver. Indeed, the driver can read data that are not already set by the user-space or the user-space and the driver are writing and reading the same area. Fix that resetting data pointers on each SNDRV_PCM_TRIGGER_START events.

[PATCH v1] usb: typec: tcpm: move tcpm_queue_vdm_unlocked to asynchronous work

by RD Babiera

A state check was previously added to tcpm_queue_vdm_unlocked to prevent a deadlock where the DisplayPort Alt Mode driver would be executing work and attempting to grab the tcpm_lock while the TCPM was holding the lock and attempting to unregister the altmode, blocking on the altmode driver's cancel_work_sync call. Because the state check isn't protected, there is a small window where the Alt Mode driver could determine that the TCPM is in a ready state and attempt to grab the lock while the TCPM grabs the lock and changes the TCPM state to one that causes the deadlock. Change tcpm_queue_vdm_unlocked to queue for tcpm_queue_vdm_work, which can perform the state check while holding the TCPM lock while the Alt Mode lock is no longer held. This requires a new struct to hold the vdm data, altmode_vdm_event.

[PATCH v1] usb: typec: tcpm: apply vbus before data bringup in tcpm_src_attach

by RD Babiera

This patch fixes Type-C compliance test TD 4.7.6 - Try.SNK DRP Connect SNKAS. tVbusON has a limit of 275ms when entering SRC_ATTACHED. Compliance testers can interpret the TryWait.Src to Attached.Src transition after Try.Snk as being in Attached.Src the entire time, so ~170ms is lost to the debounce timer. Setting the data role can be a costly operation in host mode, and when completed after 100ms can cause Type-C compliance test check TD 4.7.5.V.4 to fail. Turn VBUS on before tcpm_set_roles to meet timing requirement.

[PATCH v1] usb: typec: tcpm: delay SNK_TRY_WAIT_DEBOUNCE to SRC_TRYWAIT transition

by RD Babiera

This patch fixes Type-C Compliance Test TD 4.7.6 - Try.SNK DRP Connect SNKAS. The compliance tester moves into SNK_UNATTACHED during toggling and expects the PUT to apply Rp after tPDDebounce of detection. If the port is in SNK_TRY_WAIT_DEBOUNCE, it will move into SRC_TRYWAIT immediately and apply Rp. This violates TD 4.7.5.V.3, where the tester confirms that the PUT attaches Rp after the transitions to Unattached.SNK for tPDDebounce. Change the tcpm_set_state delay between SNK_TRY_WAIT_DEBOUNCE and SRC_TRYWAIT to tPDDebounce.

[PATCH] cpufreq: intel_pstate: Unchecked MSR aceess in legacy mode

by Srinivas Pandruvada

When turbo mode is unavailable on a Skylake-X system, executing the command: "echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo" results in an unchecked MSR access error: WRMSR to 0x199 (attempted to write 0x0000000100001300). This issue was reproduced on an OEM (Original Equipment Manufacturer) system and is not a common problem across all Skylake-X systems. This error occurs because the MSR 0x199 Turbo Engage Bit (bit 32) is set when turbo mode is disabled. The issue arises when intel_pstate fails to detect that turbo mode is disabled. Here intel_pstate relies on MSR_IA32_MISC_ENABLE bit 38 to determine the status of turbo mode. However, on this system, bit 38 is not set even when turbo mode is disabled. According to the Intel Software Developer's Manual (SDM), the BIOS sets this bit during platform initialization to enable or disable opportunistic processor performance operations. Logically, this bit should be set in such cases. However, the SDM also specifies that "OS and applications must use CPUID leaf 06H to detect processors with opportunistic processor performance operations enabled." Therefore, in addition to checking MSR_IA32_MISC_ENABLE bit 38, verify that CPUID.06H:EAX[1] is 0 to accurately determine if turbo mode is disabled.

[PATCH v3] net: mdio: mux-meson-gxl: set reversed bit when using internal phy

by Da Xue

This bit is necessary to receive packets from the internal PHY. Without this bit set, no activity occurs on the interface. Normally u-boot sets this bit, but if u-boot is compiled without net support, the interface will be up but without any activity. The vendor SDK sets this bit along with the PHY_ID bits.

[PATCH] fs/eventpoll: fix endless busy loop after timeout has expired

by Max Kellermann

After commit 0a65bc27bd64 ("eventpoll: Set epoll timeout if it's in the future"), the following program would immediately enter a busy loop in the kernel: ``` int main() { int e = epoll_create1(0); struct epoll_event event = {.events = EPOLLIN}; epoll_ctl(e, EPOLL_CTL_ADD, 0, &event); const struct timespec timeout = {.tv_nsec = 1}; epoll_pwait2(e, &event, 1, &timeout, 0); } ``` This happens because the given (non-zero) timeout of 1 nanosecond usually expires before ep_poll() is entered and then ep_schedule_timeout() returns false, but `timed_out` is never set because the code line that sets it is skipped. This quickly turns into a soft lockup, RCU stalls and deadlocks, inflicting severe headaches to the whole system. When the timeout has expired, we don't need to schedule a hrtimer, but we should set the `timed_out` variable. Therefore, I suggest moving the ep_schedule_timeout() check into the `timed_out` expression instead of skipping it.

In my setup (PV Dom0 with 4G RAM, using XFS), I shrink memory to 256M via the balloon driver after boot: xl mem-set Domain-0 256m Once memory is reduced, even running a simple command like ls usually triggers the following warning: [ 27.963562] [ T2553] page: refcount:88 mapcount:21 mapping:ffff88813ff6f6a8 index:0x110 pfn:0x10085c [ 27.963564] [ T2553] head: order:2 mapcount:83 entire_mapcount:0 nr_pages_mapped:4 pincount:0 [ 27.963565] [ T2553] memcg:ffff888003573000 [ 27.963567] [ T2553] aops:0xffffffff8226fd20 ino:82467c dentry name(?):"libc.so.6" [ 27.963570] [ T2553] flags: 0x2000000000416c(referenced|uptodate|lru|active|private|head|node=0|zone=2) [ 27.963573] [ T2553] raw: 002000000000416c ffffea0004021e88 ffffea0004021908 ffff88813ff6f6a8 [ 27.963574] [ T2553] raw: 0000000000000110 ffff88811bf06b60 0000005800000014 ffff888003573000 [ 27.963576] [ T2553] head: 002000000000416c ffffea0004021e88 ffffea0004021908 ffff88813ff6f6a8 [ 27.963577] [ T2553] head: 0000000000000110 ffff88811bf06b60 0000005800000014 ffff888003573000 [ 27.963578] [ T2553] head: 0020000000000202 ffffea0004021701 0000000400000052 00000000ffffffff [ 27.963580] [ T2553] head: 0000000300000003 8000000300000002 0000000000000014 0000000000000004 [ 27.963581] [ T2553] page dumped because: VM_WARN_ON_FOLIO((_Generic((page + nr_pages - 1), const struct page *: (const struct folio *)_compound_head(page + nr_pages - 1), struct page *: (struct folio *)_compound_head(page + nr_pages - 1))) != folio) [ 27.963590] [ T2553] ------------[ cut here ]------------ [ 27.963591] [ T2553] WARNING: CPU: 1 PID: 2553 at include/linux/rmap.h:427 __folio_rmap_sanity_checks+0x1a0/0x270 [ 27.963596] [ T2553] CPU: 1 UID: 0 PID: 2553 Comm: ls Not tainted 6.15.0-rc4-00002-ge0363f942651 #270 PREEMPT(undef) [ 27.963599] [ T2553] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-20240910_120124-localhost 04/01/2014 [ 27.963601] [ T2553] RIP: e030:__folio_rmap_sanity_checks+0x1a0/0x270 [ 27.963603] [ T2553] Code: 89 df e8 b3 7d fd ff 0f 0b e9 eb fe ff ff 48 8d 42 ff 48 39 c3 0f 84 0e ff ff ff 48 c7 c6 e8 49 5b 82 48 89 df e8 90 7d fd ff <0f> 0b e9 f8 fe ff ff 41 f7 c4 ff 0f 00 00 0f 85 b2 fe ff ff 49 8b [ 27.963605] [ T2553] RSP: e02b:ffffc90040f8fac0 EFLAGS: 00010246 [ 27.963608] [ T2553] RAX: 00000000000000e5 RBX: ffffea0004021700 RCX: 0000000000000000 [ 27.963609] [ T2553] RDX: 0000000000000000 RSI: 0000000000000001 RDI: 00000000ffffffff [ 27.963610] [ T2553] RBP: ffffc90040f8fae0 R08: 00000000ffffdfff R09: ffffffff82929308 [ 27.963612] [ T2553] R10: ffffffff82879360 R11: 0000000000000002 R12: ffffea0004021700 [ 27.963613] [ T2553] R13: 0000000000000005 R14: 0000000000000000 R15: 0000000000000005 [ 27.963625] [ T2553] FS: 00007ff06dafe740(0000) GS:ffff8880b7ccb000(0000) knlGS:0000000000000000 [ 27.963627] [ T2553] CS: e030 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 27.963628] [ T2553] CR2: 000055deb932f630 CR3: 0000000002844000 CR4: 0000000000050660 [ 27.963630] [ T2553] Call Trace: [ 27.963632] [ T2553] <TASK> [ 27.963633] [ T2553] folio_remove_rmap_ptes+0x24/0x2b0 [ 27.963635] [ T2553] unmap_page_range+0x132e/0x17e0 [ 27.963638] [ T2553] unmap_single_vma+0x81/0xd0 [ 27.963640] [ T2553] unmap_vmas+0xb5/0x180 [ 27.963642] [ T2553] exit_mmap+0x10c/0x460 [ 27.963644] [ T2553] mmput+0x59/0x120 [ 27.963647] [ T2553] do_exit+0x2d1/0xbd0 [ 27.963649] [ T2553] do_group_exit+0x2f/0x90 [ 27.963651] [ T2553] __x64_sys_exit_group+0x13/0x20 [ 27.963652] [ T2553] x64_sys_call+0x126b/0x1d70 [ 27.963655] [ T2553] do_syscall_64+0x54/0x120 [ 27.963657] [ T2553] entry_SYSCALL_64_after_hwframe+0x76/0x7e [ 27.963659] [ T2553] RIP: 0033:0x7ff06dbdbe9d [ 27.963660] [ T2553] Code: Unable to access opcode bytes at 0x7ff06dbdbe73.

I was able to bisect this issue to the commit: 10ebac4f95e7 ("mm/memory: optimize unmap/zap with PTE-mapped THP"). If I understand correctly, the folio from the first warning has 4 pages, but folio_pte_batch incorrectly counts 5 pages, because expected_pte and pte are both zero-valued PTEs, and the loop is not broken in such a case because pte_same() returns true.

The patch in the following message fixes the problem for me. It adds a check that breaks the loop when encountering non-present PTE, before the !pte_same() check. I still don't fully understand how the zero-valued PTE appears there or why this issue is triggered only when xen-balloon driver shrinks the memory. I wasn't able to reproduce it without shrinking.

[PATCH v2] 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 huge page. There is a bug in this additional check for GHCB page contained within a huge 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 huge page.

[PATCH v3] x86/sev: Do not touch VMSA pages during kdump of SNP guest memory

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> When kdump is running makedumpfile to generate vmcore and dumping SNP guest memory it touches the VMSA page of the vCPU executing kdump which then results in unrecoverable #NPF/RMP faults as the VMSA page is marked busy/in-use when the vCPU is running and subsequently causes guest softlockup/hang. Additionally other APs may be halted in guest mode and their VMSA pages are marked busy and touching these VMSA pages during guest memory dump will also cause #NPF. Issue AP_DESTROY GHCB calls on other APs to ensure they are kicked out of guest mode and then clear the VMSA bit on their VMSA pages. If the vCPU running kdump is an AP, mark it's VMSA page as offline to ensure that makedumpfile excludes that page while dumping guest memory.

Feedback on New Kafka Project

by Xiaorui Wang

Greetings, I saw you were interested in many open source project, so I wanted to share a relevant open source project I'm working on. AutoMQ is a Kafka solution developed on object storage. This offers several distinct advantages: - 10x more cost-effective than Apache Kafka. - Partition reassignment 800x faster than Kafka. - 5x higher throughput in catch-up read. I'm pleased to announce that AutoMQ has successfully simplified the operation and maintenance of Apache Kafka for Grab.com, which has greatly lowered their cloud expenditures. Is this something that could be beneficial? I'd love to hear any feedback you might have! (If it's not relevant, no problem – I won't bother you again!) Sincerely, Xiaorui github.com/automq/automq

[PATCH stable v6.6] riscv: kprobes: Fix wrong lengths passed to patch_text_nosync()

by Nam Cao

Unlike patch_text(), patch_text_nosync() takes the length in bytes, not number of instructions. It is therefore wrong for arch_prepare_ss_slot() to pass length=1 while patching one instruction. This bug was introduced by commit b1756750a397 ("riscv: kprobes: Use patch_text_nosync() for insn slots"). It has been fixed upstream by commit 51781ce8f448 ("riscv: Pass patch_text() the length in bytes"). However, beside fixing this bug, this commit does many other things, making it unsuitable for backporting. Fix it by properly passing the lengths in bytes.

[PATCH net v3 0/2] address EEE regressions on KSZ switches since v6.9 (v6.14+)

by Oleksij Rempel

This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration"). The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided. The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling. This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes. Tested on KSZ9893 hardware. Oleksij Rempel (2): net: dsa: microchip: let phylink manage PHY EEE configuration on KSZ switches net: phy: micrel: remove KSZ9477 EEE quirks now handled by phylink drivers/net/dsa/microchip/ksz_common.c | 134 +++++++++++++++++++------ drivers/net/phy/micrel.c | 7 -- include/linux/micrel_phy.h | 1 - 3 files changed, 106 insertions(+), 36 deletions(-) -- 2.39.5

[PATCH v3 6.6] iommu: Handle race with default domain setup

by Robin Murphy

[ Upstream commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 ] It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes. [ Backport: The above is true for mainline, but here we still have arch_setup_dma_ops() to worry about, which is not replayed if the default domain happens to be allocated *between* that call and subsequently reaching iommu_device_use_default_domain(), so we need an additional earlier check to cover that case. Also we're now back before the nominal commit 98ac73f99bc4 so we need to tweak the logic to depend on IOMMU_DMA as well, to avoid falsely deferring on architectures not using default domains. This then serves us back as far as f188056352bc, where this specific form of the problem first arises. ] Reported-by: Charan Teja Kalla <quic_charante(a)quicinc.com> Fixes: 98ac73f99bc4 ("iommu: Require a default_domain for all iommu drivers") Fixes: f188056352bc ("iommu: Avoid locking/unlocking for iommu_probe_device()") Link: https://lore.kernel.org/r/e88b94c9b575034a2c98a48b3d383654cbda7902.17407532… Signed-off-by: Robin Murphy <robin.murphy(a)arm.com> --- Resending as a new version with a new Message-Id so as not to confuse the tools... 6.12.y should simply have a straight cherry-pick of the mainline commit - 98ac73f99bc4 was in 6.7 so I'm not sure why autosel hasn't picked that already?

[PATCH 5.10.y 1/3] net: dsa: mv88e6xxx: fix atu_move_port_mask for 6341 family

[PATCH 6.6] iommu: Handle race with default domain setup

by Robin Murphy

[ Upstream commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 ] It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes. [ Backport: The above is true for mainline, but here we still have arch_setup_dma_ops() to worry about, which is not replayed if the default domain happens to be allocated *between* that call and subsequently reaching iommu_device_use_default_domain(), so we need an additional earlier check to cover that case. Also we're now back before the nominal commit 98ac73f99bc4 so we need to tweak the logic to depend on IOMMU_DMA as well, to avoid falsely deferring on architectures not using default domains. This then serves us back as far as f188056352bc, where this specific form of the problem first arises. ] Reported-by: Charan Teja Kalla <quic_charante(a)quicinc.com> Fixes: 98ac73f99bc4 ("iommu: Require a default_domain for all iommu drivers") Fixes: f188056352bc ("iommu: Avoid locking/unlocking for iommu_probe_device()") Link: https://lore.kernel.org/r/e88b94c9b575034a2c98a48b3d383654cbda7902.17407532… Signed-off-by: Robin Murphy <robin.murphy(a)arm.com> --- drivers/iommu/iommu.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/drivers/iommu/iommu.c b/drivers/iommu/iommu.c index 3f1029c0825e..29b48a6a0275 100644 --- a/drivers/iommu/iommu.c +++ b/drivers/iommu/iommu.c @@ -566,6 +566,17 @@ int iommu_probe_device(struct device *dev) mutex_lock(&iommu_probe_device_lock); ret = __iommu_probe_device(dev, NULL); mutex_unlock(&iommu_probe_device_lock); + + /* + * The dma_configure replay paths need bus_iommu_probe() to + * finish before they can call arch_setup_dma_ops() + */ + if (IS_ENABLED(CONFIG_IOMMU_DMA) && !ret && dev->iommu_group) { + mutex_lock(&dev->iommu_group->mutex); + if (!dev->iommu_group->default_domain) + ret = -EPROBE_DEFER; + mutex_unlock(&dev->iommu_group->mutex); + } if (ret) return ret; @@ -3149,6 +3160,11 @@ int iommu_device_use_default_domain(struct device *dev) return 0; mutex_lock(&group->mutex); + /* We may race against bus_iommu_probe() finalising groups here */ + if (!group->default_domain) { + ret = -EPROBE_DEFER; + goto unlock_out; + } if (group->owner_cnt) { if (group->owner || !iommu_is_default_domain(group) || !xa_empty(&group->pasid_array)) { -- 2.39.2.101.g768bb238c484.dirty

[PATCH stable 5.15/6.1/6.6] af_unix: Clear oob_skb in scan_inflight().

by Kuniyuki Iwashima

Embryo socket is not queued in gc_candidates, so we can't drop a reference held by its oob_skb. Let's say we create listener and embryo sockets, send the listener's fd to the embryo as OOB data, and close() them without recv()ing the OOB data. There is a self-reference cycle like listener -> embryo.oob_skb -> listener , so this must be cleaned up by GC. Otherwise, the listener's refcnt is not released and sockets are leaked: # unshare -n # cat /proc/net/protocols | grep UNIX-STREAM UNIX-STREAM 1024 0 -1 NI 0 yes kernel ... # python3 >>> from array import array >>> from socket import * >>> >>> s = socket(AF_UNIX, SOCK_STREAM) >>> s.bind('\0test\0') >>> s.listen() >>> >>> c = socket(AF_UNIX, SOCK_STREAM) >>> c.connect(s.getsockname()) >>> c.sendmsg([b'x'], [(SOL_SOCKET, SCM_RIGHTS, array('i', [s.fileno()]))], MSG_OOB) 1 >>> quit() # cat /proc/net/protocols | grep UNIX-STREAM UNIX-STREAM 1024 3 -1 NI 0 yes kernel ... ^^^ 3 sockets still in use after FDs are close()d Let's drop the embryo socket's oob_skb ref in scan_inflight(). This also fixes a racy access to oob_skb that commit 9841991a446c ("af_unix: Update unix_sk(sk)->oob_skb under sk_receive_queue lock.") fixed for the new Tarjan's algo-based GC.

[PATCH] drm/v3d: Add job to pending list if the reset was skipped

by Maíra Canal

When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.

[PATCH 6.6.y v2 1/4] net: dsa: mv88e6xxx: fix atu_move_port_mask for 6341 family

by Marek Behún

commit 4ae01ec007716986e1a20f1285eb013cbf188830 upstream. The atu_move_port_mask for 6341 family (Topaz) is 0xf, not 0x1f. The PortVec field is 8 bits wide, not 11 as in 6390 family. Fix this.

[PATCH 6.1.y v3] net/sched: act_mirred: don't override retval if we already lost the skb

[PATCH net v2 0/2] address EEE regressions on KSZ switches since v6.9 (v6.14+)

by Oleksij Rempel

This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration"). The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided. The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling. This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes. Tested on KSZ9893 hardware.

Mhm, why has that patch been picked up for backporting? It's a cleanup and not a bug fix. When some other fix depends on it it's probably ok to backport it as well, but stand alone it would probably rather hurt than help, Regards, Christian. > > > > commit 09a1b6ca7c7d9c07c702479646a0a8cfa2329e11 > Author: Ramesh Errabolu <Ramesh.Errabolu(a)amd.com> > Date: Wed Feb 24 20:48:06 2021 -0600 > > drm/amdgpu: Remove amdgpu_device arg from free_sgt api (v2) > > [ Upstream commit 5392b2af97dc5802991f953eb2687e538da4688c ] > > Currently callers have to provide handle of amdgpu_device, > which is not used by the implementation.

[PATCH v1] drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()

Build failure due to backport of "bpf: Add namespace to BPF internal symbols"

by Shung-Hsi Yu

Hi Sasha, bpf-add-namespace-to-bpf-internal-symbols.patch is stable-queue.git seems like the culprit responsible for build failure in stable 6.12 and earlier (log below). The reason is likely due to the lack of commit cdd30ebb1b9f ("module: Convert symbol namespace to string literal") before v6.13. Getting rid of the quotes s/"BPF_INTERNAL"/BPF_INTERNAL/ probably would be enough to fix it.

[PATCH V3] arm64/boot: Enable EL2 requirements for FEAT_PMUv3p9

by Anshuman Khandual

FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 access from EL1 requires appropriate EL2 fine grained trap configuration via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2. Otherwise such register accesses will result in traps into EL2. Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers. Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2 based registers to be accessible in EL2.

[PATCH v2] 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 within amdgpu_ras_do_page_retirement(), which also does not check the return value.

[PATCH] fs/erofs/fileio: call erofs_onlinefolio_split() after bio_add_folio()

by Max Kellermann

If bio_add_folio() fails (because it is full), erofs_fileio_scan_folio() needs to submit the I/O request via erofs_fileio_rq_submit() and allocate a new I/O request with an empty `struct bio`. Then it retries the bio_add_folio() call. However, at this point, erofs_onlinefolio_split() has already been called which increments `folio->private`; the retry will call erofs_onlinefolio_split() again, but there will never be a matching erofs_onlinefolio_end() call. This leaves the folio locked forever and all waiters will be stuck in folio_wait_bit_common(). This bug has been added by commit ce63cb62d794 ("erofs: support unencoded inodes for fileio"), but was practically unreachable because there was room for 256 folios in the `struct bio` - until commit 9f74ae8c9ac9 ("erofs: shorten bvecs[] for file-backed mounts") which reduced the array capacity to 16 folios. It was now trivial to trigger the bug by manually invoking readahead from userspace, e.g.: posix_fadvise(fd, 0, st.st_size, POSIX_FADV_WILLNEED); This should be fixed by invoking erofs_onlinefolio_split() only after bio_add_folio() has succeeded. This is safe: asynchronous completions invoking erofs_onlinefolio_end() will not unlock the folio because erofs_fileio_scan_folio() is still holding a reference to be released by erofs_onlinefolio_end() at the end.

[PATCH v2] usb: cdnsp: fix L1 resume issue for RTL_REVISION_NEW_LPM version

by Pawel Laszczak

The controllers with rtl version larger 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 larger 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] configfs-tsm-report: Fix NULL dereference of tsm_ops

by Dan Williams

Unlike sysfs, the lifetime of configfs objects is controlled by userspace. There is no mechanism for the kernel to find and delete all created config-items. Instead, the configfs-tsm-report mechanism has an expectation that tsm_unregister() can happen at any time and cause established config-item access to start failing. That expectation is not fully satisfied. While tsm_report_read(), tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely fail if tsm_ops have been unregistered, tsm_report_privlevel_store() tsm_report_provider_show() fail to check for ops registration. Add the missing checks for tsm_ops having been removed. Now, in supporting the ability for tsm_unregister() to always succeed, it leaves the problem of what to do with lingering config-items. The expectation is that the admin that arranges for the ->remove() (unbind) of the ${tsm_arch}-guest driver is also responsible for deletion of all open config-items. Until that deletion happens, ->probe() (reload / bind) of the ${tsm_arch}-guest driver fails. This allows for emergency shutdown / revocation of attestation interfaces, and requires coordinated restart.

[PATCH v3 0/2] Restrict devmem for confidential VMs

by Dan Williams

Changes since v2 [1]: * Drop the new x86_platform_op and just use cc_platform_has(CC_ATTR_GUEST_MEM_ENCRYPT) directly where needed (Naveen) * Make the restriction identical to lockdown and stop playing games with devmem_is_allowed() * Ensure that CONFIG_IO_STRICT_DEVMEM is enabled to avoid conflicting mappings for userspace mappings of PCI MMIO. The original response to Nikolay's report of an SEPT violation triggered by /dev/mem access to private memory was "let's just turn off /dev/mem". After some machinations of x86_platform_ops to block a subset of problematic access, spelunking the history of devmem_is_allowed() returning "2" to enable some compatibility benefits while blocking access, and discovering that userspace depends buggy kernel behavior for mmap(2) of the first 1MB of memory on x86, the proposal has circled back to "disable /dev/mem". Require both STRICT_DEVMEM and IO_STRICT_DEVMEM for x86 confidential guests to close /dev/mem hole while still allowing for userspace mapping of PCI MMIO as long as the kernel and userspace are not mapping the range at the same time. The range_is_allowed() cleanup is not strictly necessary, but might as well close a 17 year-old "TODO". --- Dan Williams (2): x86/devmem: Remove duplicate range_is_allowed() definition x86/devmem: Drop /dev/mem access for confidential guests arch/x86/Kconfig | 4 ++++ arch/x86/mm/pat/memtype.c | 31 ++++--------------------------- drivers/char/mem.c | 27 +++++++++------------------ include/linux/io.h | 21 +++++++++++++++++++++ 4 files changed, 38 insertions(+), 45 deletions(-) base-commit: 0af2f6be1b4281385b618cb86ad946eded089ac8

[REGRESSION] 6.14.3 panic - kernel NULL pointer dereference in htb_dequeue

by Alan J. Wylie

#regzbot introduced: 6.14.2..6.14.3 Since 6.14.3 I have been seeing random panics, all in htb_dequeue. 6.14.2 was fine. One only happened 8 hours after the reboot, so bisecting would be prolonged, since I have no idea what is triggering the crash. I've captured three panics with netconsole. All are very similar. I've also included the script I use to initialise tc. As well as when the ppp over ethernet interface comes up, I also run this every 5 minutes as a cron job since my ADSL line can fluctuate between 22 and 30 Mb/s. However, from the timings of the last few lines in /var/log/messages before the crash, it doesn't seem that this is directly related. Finally, I've decoded the first panic.

[PATCH] f2fs: fix to do sanity check on sit_bitmap_size

by Chao Yu

w/ below testcase, resize will generate a corrupted image which contains inconsistent metadata, so when mounting such image, it will trigger kernel panic: touch img truncate -s $((512*1024*1024*1024)) img mkfs.f2fs -f img $((256*1024*1024)) resize.f2fs -s -i img -t $((1024*1024*1024)) mount img /mnt/f2fs ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.h:863!

[PATCH net V3] 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 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. v2->v3: ------- - Removed RSS feature toggling as checksum offloading functions correctly without it 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 | 11 +++++++++-- drivers/net/ethernet/amd/xgbe/xgbe.h | 4 ++++ 4 files changed, 42 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..51b4adb8a404 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c @@ -2290,10 +2290,17 @@ 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

[PATCH] asm-generic/io.h: Skip trace helpers if rwmmio events are disabled

by Varad Gautam

With `CONFIG_TRACE_MMIO_ACCESS=y`, the `{read,write}{b,w,l,q}{_relaxed}()` mmio accessors unconditionally call `log_{post_}{read,write}_mmio()` helpers, which in turn call the ftrace ops for `rwmmio` trace events This adds a performance penalty per mmio accessor call, even when `rwmmio` events are disabled at runtime (~80% overhead on local measurement). Guard these with `tracepoint_enabled()`.

[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

[PATCH] x86/boot/sev: Support memory acceptance in the EFI stub under SVSM

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> Commit d54d610243a4 ("x86/boot/sev: Avoid shared GHCB page for early memory acceptance") provided a fix for SEV-SNP memory acceptance from the EFI stub when running at VMPL #0. However, that fix was insufficient for SVSM SEV-SNP guests running at VMPL >0, as those rely on a SVSM calling area, which is a shared buffer whose address is programmed into a SEV-SNP MSR, and the SEV init code that sets up this calling area executes much later during the boot. Given that booting via the EFI stub at VMPL >0 implies that the firmware has configured this calling area already, reuse it for performing memory acceptance in the EFI stub.

The dangling IRTE can result in interrupts being incorrectly delivered to the guest, and in the worst case scenario can result in use-after-free, e.g. if the VM is torn down, but the underlying host IRQ isn't freed.

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. 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. This was added to 6.1, 5.15, and 5.10, but it is also needed for 6.6. 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 v3 1/2] platform/x86: int3472: add hpd pin support

by Dongcheng Yan

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.

[PATCH v2] drm/amdgpu: check a user-provided number of BOs in list

The user can set any value to the variable ‘bo_number’, via the ioctl command DRM_IOCTL_AMDGPU_BO_LIST. This will affect the arithmetic expression ‘in->bo_number * in->bo_info_size’, which is prone to overflow. Add a valid value check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH v2 1/2] usb: typec: ucsi: displayport: Fix deadlock

by Andrei Kuchynski

This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector mutex is only locked if a connection is established and the partner pointer is valid. 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.

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 ?

But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger: Unable to handle kernel paging request at virtual address ffff8000816c0400 gicv2m_get_fwnode+0x0/0x58 (P) pci_set_bus_msi_domain+0x74/0x88 pci_register_host_bridge+0x194/0x548 This is easily reproducible on a Juno board with ACPI boot.

The patch does permit the offending YUV420 @ 59.94 phy_freq and vclk_freq mode to match in calculations. It also results in all fractional rates being unavailable for use.

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.

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.

[PATCH] arm64: dts: qcom: x1e80100: Add GFX power domain to GPU clock controller

by Abel Vesa

According to documentation, the VDD_GFX is powering up the whole GPU subsystem. The VDD_GFX is routed through the RPMh GFX power domain. So tie the RPMh GFX power domain to the GPU clock controller.

IPC drop down on AMD epyc 7702P

by Jean-Baptiste Roquefere

Hi, We (Ateme, a video encoding company) may have found an unwanted behavior in the scheduler since 5.10 (commit 16b0a7a1a0af), then 5.16 (commit c5b0a7eefc70), then 5.19 (commit not found yet), then maybe some other commits from 5.19 to 6.12, with a consequence of IPC decrease. Problem still appears on lasts 6.12, 6.13 and 6.14 We have reverted both 16b0a7a1a0af and c5b0a7eefc70 commits that reduce our performances (see fair.patch attached, applicable on 6.12.17). Performances increase but still doesnt reach our reference on 5.4.152. Instead of trying to find every single commits from 5.18 to 6.12 that could decrease our performance, I chosed to bench 5.4.152 versus 6.12.17 with and without fair.patch. The problem appeared clear : a lot of CPU migrations go out of CCX, then L3 miss, then IPC decrease. Context of our bench: video decoder which work at a regulated speed, 1 process, 21 main threads, everyone of them creates 10 threads, 8 of them have a fine granularity, meaning they go to sleep quite often, giving the scheduler a lot of opportunities to act). Hardware is an AMD Epyc 7702P, 128 cores, grouped by shared LLC 4 cores +4 hyperthreaded cores. NUMA topology is set by the BIOS to 1 node per socket. Every pthread are created with default attributes. I use AMDuProf (-C -A system -a -m ipc,l1,l2,l3,memory) for CPU Utilization (%), CPU effective freq, IPC, L2 access (pti), L2 miss (pti), L3 miss (absolute) and Mem (GB/s, and perf (stat -d -d -d -a) for Context switches, CPU migrations and Real time (s). We noted that upgrade 5.4.152 to 6.12.17 without any special preempt configuration : Two fold increase in CPU migration 30% memory bandwidth increase 20% L3 cache misses increase 10% IPC decrease With the attached fair.patch applied to 6.12.17 (reminder : this patch reverts one commit appeared in 5.10 and another in 5.16) we managed to reduce CPU migrations and increase IPC but not as much as we had on 5.4.152. Our goal is to keep kernel "clean" without any patch (we don't want to apply and maintain fair.patch) then for the rest of my email we will consider stock kernel 6.12.17. I've reduced the "sub threads count" to stays below 128 threads. Then still 21 main threads and instead of 10 worker per main thread I set 5 workers (4 of them with fine granularity) giving 105 pthreads -> everything goes fine in 6.12.17, no extra CPU migration, no extra memory bandwidth... But as soon as we increase worker threads count (10 instead of 5) the problem appears. We know our decoder may have too many threads but that's out of our scope, it has been designed like that some years ago and moving from "lot of small threads to few of big thread" is for now not possible. We have a work around : we group threads using pthread affinities. Every main thread (and by inheritance of affinities every worker threads) on a single CCX so we reduce the L3 miss for them, then decrease memory bandwidth, then finally increasing IPC. With that solution, we go above our original performances, for both kernels, and they perform at the same level. However, it is impractical to productize as such. I've tried many kernel build configurations (CONFIG_PREMPT_*, CONFIG_SCHEDULER_*, tuning of fair.c:sysctl_sched_migration_cost) on 6.12.17, 6.12.21 (longterm), 6.13.9 (mainline), and 6.14.0 Nothing changes. Q: Is there anyway to tune the kernel so we can get our performance back without using the pthread affinities work around ? Feel free to ask an archive containing binaries and payload. I first posted on https://bugzilla.kernel.org/show_bug.cgi?id=220000 but one told me the best way to get answers where these mailing lists Regards, Jean-Baptiste Roquefere, Ateme Attached bench.tar.gz : * bench/fair.patch * bench/bench.ods with 2 sheets : - regulated : decoder speed is regulated to keep real time constant - no regul : decoder speed is not regulated and uses from 1 to 76 main threads with 10 worker per main thread * bench/regulated.csv : bench.ods:regulated exported in csv format * bench/not-regulated : bench.ods:no regul exported in csv format

[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().

[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] xfs: fix diff_two_keys calculation for cnt btree

by Fedor Pchelkin

Currently the difference is computed on 32-bit unsigned values although eventually it is stored in a variable of int64_t type. This gives awkward results, e.g. when the diff _should_ be negative, it is represented as some large positive int64_t value. Perform the calculations directly in int64_t as all other diff_two_keys routines actually do. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.

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] drm/dp: Fix Write_Status_Update_Request AUX request format

by Wayne Lin

[Why] Notice AUX request format of I2C-over-AUX with Write_Status_Update_Request flag set is incorrect. It should be address only request without length and data like: "SYNC->COM3:0 (= 0110)|0000-> 0000|0000-> 0|7-bit I2C address (the same as the last)-> STOP->". [How] Refer to DP v2.1 Table 2-178, correct the Write_Status_Update_Request to be address only request. Note that we might receive 0 returned by aux->transfer() when receive reply I2C_ACK|AUX_ACK of Write_Status_Update_Request transaction. Which indicating all data bytes get written. We should avoid to return 0 bytes get transferred under this case.

[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] MIPS: CPS: Fix potential NULL pointer dereferences in cps_prepare_cpus()

by Thorsten Blum

Check the return values of kcalloc() and exit early to avoid potential NULL pointer dereferences. Compile-tested only.
