[PATCH AUTOSEL 6.10 01/16] drm/fb-helper: Don't schedule_work() to flush frame buffer during panic()

by Sasha Levin

From: Qiuxu Zhuo <qiuxu.zhuo(a)intel.com> [ Upstream commit 833cd3e9ad8360785b6c23c82dd3856df00732d9 ] Sometimes the system [1] hangs on x86 I/O machine checks. However, the expected behavior is to reboot the system, as the machine check handler ultimately triggers a panic(), initiating a reboot in the last step. The root cause is that sometimes the panic() is blocked when drm_fb_helper_damage() invoking schedule_work() to flush the frame buffer. This occurs during the process of flushing all messages to the frame buffer driver as shown in the following call trace: Machine check occurs [2]: panic() console_flush_on_panic() console_flush_all() console_emit_next_record() con->write() vt_console_print() hide_cursor() vc->vc_sw->con_cursor() fbcon_cursor() ops->cursor() bit_cursor() soft_cursor() info->fbops->fb_imageblit() drm_fbdev_generic_defio_imageblit() drm_fb_helper_damage_area() drm_fb_helper_damage() schedule_work() // <--- blocked here ... emergency_restart() // wasn't invoked, so no reboot. During panic(), except the panic CPU, all the other CPUs are stopped. In schedule_work(), the panic CPU requires the lock of worker_pool to queue the work on that pool, while the lock may have been token by some other stopped CPU. So schedule_work() is blocked. Additionally, during a panic(), since there is no opportunity to execute any scheduled work, it's safe to fix this issue by skipping schedule_work() on 'oops_in_progress' in drm_fb_helper_damage(). [1] Enable the kernel option CONFIG_FRAMEBUFFER_CONSOLE, CONFIG_DRM_FBDEV_EMULATION, and boot with the 'console=tty0' kernel command line parameter. [2] Set 'panic_timeout' to a non-zero value before calling panic().

[PATCH 2/2] drm/xe/display: Make display suspend/resume work on discrete

Before commit eea83d896e31 ("ntp: NTP4 user space bits update") the user supplied value was sanity checked to be in the operating range. That change removed the sanity check and relied on clamping after incrementing which does not work correctly when the user supplied value is in the overflow zone of the '+ 4' operation. The operation requires CAP_SYS_TIME and the side effect of the overflow is NTP getting out of sync. Similar to the fixups for time_maxerror and time_esterror, clamp the user space supplied value to the operating range.

As a result the effect of that clock_was_set() notification is incomplete and might result in timers expiring late because the hrtimer code does not re-evaluate the affected clock bases.

[PATCH v2 1/1] hrtimer: Ignore slack time for RT tasks in hrtimer_start_range_ns()

by Felix Moessbauer

RT tasks do not have any timerslack, as this induces jitter. By that, the timer slack is already ignored in the nanosleep family and schedule_hrtimeout_range() (fixed in 0c52310f2600). The hrtimer_start_range_ns function is indirectly used by glibc-2.33+ for timed waits on condition variables. These are sometimes used in RT applications for realtime queue processing. At least on the combination of kernel 5.10 and glibc-2.31, the timed wait on condition variables in rt tasks was precise (no slack), however glibc-2.33 changed the internal wait implementation, exposing this oversight. Make the timer slack consistent across all hrtimer programming code, by ignoring the timerslack for tasks with rt policies also in the last remaining location in hrtimer_start_range_ns().

CI build failure in v6.6-rt

by Clark Williams

Greg, Kernel CI is reporting a build failure on v6.6-rt: https://grafana.kernelci.org/d/build/build?orgId=1&var-datasource=default&v… It's in arch/riscv/kernel/cpufeature.c where a return statement in check_unaligned_access() doesn't have a value (and check_unaligned_access returns int). Is 6.6 stable supporting RiscV? If so then we either have to fix that return, or backport the refactor of arch/riscv/kernel/cpufeature.c (f413aae96cda0). If it's not then who should I talk to about turning off riscv CI builds for v6.6-rt? Thanks, Clark

[REGRESSION] [PATCH v2] net: missing check virtio

by Blake Sperling

Hello, I noticed a regression from v.6.6.43 to v6.6.44 caused by this commit. When using virtio NIC with a QEMU/KVM Windows guest, network traffic from the VM stalls in the outbound (upload) direction.This affects remote access and file shares most noticeably, and the inbound (download) direction does not have the issue. iperf3 will show consistent results, 0 bytes/sec when initiating a test within the guest to a server on LAN, and reverse will be full speed. Nothing out of the ordinary in host dmesg or guest Event Viewer while the behavior is being displayed. Crucially, this only seems to affect Windows guests, a Ubuntu guest with the same NIC configuration works fine in both directions. I wonder if NetKVM guest drivers may be related, the current latest version of the drivers (v248) did not make a difference, but it is several months old. Let me know if there are any further tests or info I can provide, thanks!

[PATCH v2] usb: dwc3: Runtime get and put usb power_supply handle

by Kyle Tso

It is possible that the usb power_supply is registered after the probe of dwc3. In this case, trying to get the usb power_supply during the probe will fail and there is no chance to try again. Also the usb power_supply might be unregistered at anytime so that the handle of it in dwc3 would become invalid. To fix this, get the handle right before calling to power_supply functions and put it afterward.

In particular, on arm tasks without ADDR_LIMIT_32BIT, the STACK_TOP value is less than 128MB, so it's impossible to fit such a gap in. Only enforce this minimum if MIN_GAP < MAX_GAP, as we'd prefer to honour MAX_GAP, which is defined proportionally, so scales better and always leaves us with both _some_ stack space and some room for mmap. This fixes the usercopy KUnit test suite on 32-bit arm, as it doesn't set any personality flags so gets the default (in this case 26-bit) task size. This test can be run with: ./tools/testing/kunit/kunit.py run --arch arm usercopy --make_options LLVM=1 Link: https://lkml.kernel.org/r/20240803074642.1849623-2-davidgow@google.com Fixes: dba79c3df4a2 ("arm: use generic mmap top-down layout and brk randomization") Signed-off-by: David Gow <davidgow(a)google.com> Cc: Alexandre Ghiti <alex(a)ghiti.fr> Cc: Kees Cook <kees(a)kernel.org> Cc: Linus Walleij <linus.walleij(a)linaro.org> Cc: Luis Chamberlain <mcgrof(a)kernel.org> Cc: Mark Rutland <mark.rutland(a)arm.com> Cc: Russell King <linux(a)armlinux.org.uk> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/util.c~mm-only-enforce-minimum-stack-gap-size-if-its-sensible +++ a/mm/util.c @@ -463,7 +463,7 @@ static unsigned long mmap_base(unsigned if (gap + pad > gap) gap += pad; - if (gap < MIN_GAP) + if (gap < MIN_GAP && MIN_GAP < MAX_GAP) gap = MIN_GAP; else if (gap > MAX_GAP) gap = MAX_GAP; _ Patches currently in -mm which might be from davidgow(a)google.com are mm-only-enforce-minimum-stack-gap-size-if-its-sensible.patch

[PATCH UEK-4.1-QU7 1/3] hwrng: core - Fix page fault dead lock on mmap-ed hwrng

by lugomgom

From: Herbert Xu <herbert(a)gondor.apana.org.au> commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream. There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user.

Its filename is crash-fix-riscv64-crash-memory-reserve-dead-loop.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Jinjie Ruan <ruanjinjie(a)huawei.com> Subject: crash: Fix riscv64 crash memory reserve dead loop Date: Fri, 2 Aug 2024 17:01:05 +0800 On RISCV64 Qemu machine with 512MB memory, cmdline "crashkernel=500M,high" will cause system stall as below: Zone ranges: DMA32 [mem 0x0000000080000000-0x000000009fffffff] Normal empty Movable zone start for each node Early memory node ranges node 0: [mem 0x0000000080000000-0x000000008005ffff] node 0: [mem 0x0000000080060000-0x000000009fffffff] Initmem setup node 0 [mem 0x0000000080000000-0x000000009fffffff] (stall here) commit 5d99cadf1568 ("crash: fix x86_32 crash memory reserve dead loop bug") fix this on 32-bit architecture. However, the problem is not completely solved. If `CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX` on 64-bit architecture, for example, when system memory is equal to CRASH_ADDR_LOW_MAX on RISCV64, the following infinite loop will also occur: -> reserve_crashkernel_generic() and high is true -> alloc at [CRASH_ADDR_LOW_MAX, CRASH_ADDR_HIGH_MAX] fail -> alloc at [0, CRASH_ADDR_LOW_MAX] fail and repeatedly (because CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX). Before refactor in commit 9c08a2a139fe ("x86: kdump: use generic interface to simplify crashkernel reservation code"), x86 do not try to reserve crash memory at low if it fails to alloc above high 4G. However before refator in commit fdc268232dbba ("arm64: kdump: use generic interface to simplify crashkernel reservation"), arm64 try to reserve crash memory at low if it fails above high 4G. For 64-bit systems, this attempt is less beneficial than the opposite, remove it to fix this bug and align with native x86 implementation. After this patch, it print: cannot allocate crashkernel (size:0x1f400000) Link: https://lkml.kernel.org/r/20240802090105.3871929-1-ruanjinjie@huawei.com Fixes: 39365395046f ("riscv: kdump: use generic interface to simplify crashkernel reservation") Signed-off-by: Jinjie Ruan <ruanjinjie(a)huawei.com> Acked-by: Baoquan He <bhe(a)redhat.com> Cc: Albert Ou <aou(a)eecs.berkeley.edu> Cc: Chen Jiahao <chenjiahao16(a)huawei.com> Cc: Dave Young <dyoung(a)redhat.com> Cc: Palmer Dabbelt <palmer(a)dabbelt.com> Cc: Paul Walmsley <paul.walmsley(a)sifive.com> Cc: Vivek Goyal <vgoyal(a)redhat.com> Cc: Alexandre Ghiti <alex(a)ghiti.fr> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- kernel/crash_reserve.c | 9 --------- 1 file changed, 9 deletions(-) --- a/kernel/crash_reserve.c~crash-fix-riscv64-crash-memory-reserve-dead-loop +++ a/kernel/crash_reserve.c @@ -416,15 +416,6 @@ retry: goto retry; } - /* - * For crashkernel=size[KMG],high, if the first attempt was - * for high memory, fall back to low memory. - */ - if (high && search_end == CRASH_ADDR_HIGH_MAX) { - search_end = CRASH_ADDR_LOW_MAX; - search_base = 0; - goto retry; - } pr_warn("cannot allocate crashkernel (size:0x%llx)\n", crash_size); return; _ Patches currently in -mm which might be from ruanjinjie(a)huawei.com are crash-fix-riscv64-crash-memory-reserve-dead-loop.patch crash-fix-x86_32-crash-memory-reserve-dead-loop-bug.patch crash-fix-x86_32-crash-memory-reserve-dead-loop.patch arm-use-generic-interface-to-simplify-crashkernel-reservation.patch crash-fix-crash-memory-reserve-exceed-system-memory-bug.patch

[PATCH 1/5] HID: wacom: Defer calculation of resolution until resolution_code is known

by Gerecke, Jason

From: Jason Gerecke <jason.gerecke(a)wacom.com> The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ) for historic reasons. When the code to support twist was introduced in commit 50066a042da5 ("HID: wacom: generic: Add support for height, tilt, and twist usages"), we were careful to write it in such a way that it had HID calculate the resolution of the twist axis assuming ABS_RZ instead (so that we would get correct angular behavior). This was broken with the introduction of commit 08a46b4190d3 ("HID: wacom: Set a default resolution for older tablets"), which moved the resolution calculation to occur *before* the adjustment from ABS_Z to ABS_RZ occurred. This commit moves the calculation of resolution after the point that we are finished setting things up for its proper use.

[PATCH v4] mm/hugetlb: fix hugetlb vs. core-mm PT locking

by David Hildenbrand

We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page table walking code in the codebase. Turns out that we missed one page table locking detail: page table locking for hugetlb folios that are not mapped using a single PMD/PUD. Assume we have hugetlb folio that spans multiple PTEs (e.g., 64 KiB hugetlb folios on arm64 with 4 KiB base page size). GUP, as it walks the page tables, will perform a pte_offset_map_lock() to grab the PTE table lock. However, hugetlb that concurrently modifies these page tables would actually grab the mm->page_table_lock: with USE_SPLIT_PTE_PTLOCKS, the locks would differ. Something similar can happen right now with hugetlb folios that span multiple PMDs when USE_SPLIT_PMD_PTLOCKS. This issue can be reproduced [1], for example triggering: [ 3105.936100] ------------[ cut here ]------------ [ 3105.939323] WARNING: CPU: 31 PID: 2732 at mm/gup.c:142 try_grab_folio+0x11c/0x188 [ 3105.944634] Modules linked in: [...] [ 3105.974841] CPU: 31 PID: 2732 Comm: reproducer Not tainted 6.10.0-64.eln141.aarch64 #1 [ 3105.980406] Hardware name: QEMU KVM Virtual Machine, BIOS edk2-20240524-4.fc40 05/24/2024 [ 3105.986185] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 3105.991108] pc : try_grab_folio+0x11c/0x188 [ 3105.994013] lr : follow_page_pte+0xd8/0x430 [ 3105.996986] sp : ffff80008eafb8f0 [ 3105.999346] x29: ffff80008eafb900 x28: ffffffe8d481f380 x27: 00f80001207cff43 [ 3106.004414] x26: 0000000000000001 x25: 0000000000000000 x24: ffff80008eafba48 [ 3106.009520] x23: 0000ffff9372f000 x22: ffff7a54459e2000 x21: ffff7a546c1aa978 [ 3106.014529] x20: ffffffe8d481f3c0 x19: 0000000000610041 x18: 0000000000000001 [ 3106.019506] x17: 0000000000000001 x16: ffffffffffffffff x15: 0000000000000000 [ 3106.024494] x14: ffffb85477fdfe08 x13: 0000ffff9372ffff x12: 0000000000000000 [ 3106.029469] x11: 1fffef4a88a96be1 x10: ffff7a54454b5f0c x9 : ffffb854771b12f0 [ 3106.034324] x8 : 0008000000000000 x7 : ffff7a546c1aa980 x6 : 0008000000000080 [ 3106.038902] x5 : 00000000001207cf x4 : 0000ffff9372f000 x3 : ffffffe8d481f000 [ 3106.043420] x2 : 0000000000610041 x1 : 0000000000000001 x0 : 0000000000000000 [ 3106.047957] Call trace: [ 3106.049522] try_grab_folio+0x11c/0x188 [ 3106.051996] follow_pmd_mask.constprop.0.isra.0+0x150/0x2e0 [ 3106.055527] follow_page_mask+0x1a0/0x2b8 [ 3106.058118] __get_user_pages+0xf0/0x348 [ 3106.060647] faultin_page_range+0xb0/0x360 [ 3106.063651] do_madvise+0x340/0x598 Let's make huge_pte_lockptr() effectively use the same PT locks as any core-mm page table walker would. Add ptep_lockptr() to obtain the PTE page table lock using a pte pointer -- unfortunately we cannot convert pte_lockptr() because virt_to_page() doesn't work with kmap'ed page tables we can have with CONFIG_HIGHPTE. Handle CONFIG_PGTABLE_LEVELS correctly by checking in reverse order, such that when e.g., CONFIG_PGTABLE_LEVELS==2 with PGDIR_SIZE==P4D_SIZE==PUD_SIZE==PMD_SIZE will work as expected. Document why that works. There is one ugly case: powerpc 8xx, whereby we have an 8 MiB hugetlb folio being mapped using two PTE page tables. While hugetlb wants to take the PMD table lock, core-mm would grab the PTE table lock of one of both PTE page tables. In such corner cases, we have to make sure that both locks match, which is (fortunately!) currently guaranteed for 8xx as it does not support SMP and consequently doesn't use split PT locks.

This is problematic when a route, configured in a vrf, uses an interface from another vrf (aka route leak). The original vrf does not own the selected source address.

[PATCH net 0/7] mptcp: fix endpoints with 'signal' and 'subflow' flags

by Matthieu Baerts (NGI0)

When looking at improving the user experience around the MPTCP endpoints setup, I noticed that setting an endpoint with both the 'signal' and the 'subflow' flags -- as it has been done in the past by users according to bug reports we got -- was resulting on only announcing the endpoint, but not using it to create subflows: the 'subflow' flag was then ignored. My initial thought was to modify IPRoute2 to warn the user when the two flags were set, but it doesn't sound normal to ignore one of them. I then looked at modifying the kernel not to allow having the two flags set, but when discussing about that with Mat, we thought it was maybe not ideal to do that, as there might be use-cases, we might break some configs. Then I saw it was working before v5.17. So instead, I fixed the support on the kernel side (patch 5) using Paolo's suggestion. This also includes a fix on the options side (patch 1: for v5.11+), an explicit deny of some options combinations (patch 2: for v5.18+), and some refactoring (patches 3 and 4) to ease the inclusion of the patch 5. While at it, I added a new selftest (patch 7) to validate this case -- including a modification of the chk_add_nr helper to inverse the sides were the counters are checked (patch 6) -- and allowed ADD_ADDR echo just after the MP_JOIN 3WHS. The selftests modification have the same Fixes tag as the previous commit, but no 'Cc: Stable': if the backport can work, that's good -- but it still need to be verified by running the selftests -- if not, no need to worry, many CIs will use the selftests from the last stable version to validate previous stable releases.

[PATCH iwl-net 2/3] idpf: fix memleak in vport interrupt configuration

by Alexander Lobakin

From: Michal Kubiak <michal.kubiak(a)intel.com> The initialization of vport interrupt consists of two functions: 1) idpf_vport_intr_init() where a generic configuration is done 2) idpf_vport_intr_req_irq() where the irq for each q_vector is requested. The first function used to create a base name for each interrupt using "kasprintf()" call. Unfortunately, although that call allocated memory for a text buffer, that memory was never released. Fix this by removing creating the interrupt base name in 1). Instead, always create a full interrupt name in the function 2), because there is no need to create a base name separately, considering that the function 2) is never called out of idpf_vport_intr_init() context.

These igc bug fixes are sent as a patch series because: 1. The two patches below remove the reliance on using the qbv_count field. "igc: Fix qbv_config_change_errors logics" "igc: Fix reset adapter logics when tx mode change" qbv_count field will be removed in future patch via iwl-next. 2. The patch "igc: Fix qbv tx latency by setting gtxoffset" reuse the function igc_tsn_will_tx_mode_change() which was created in the patch: "igc: Fix reset adapter logics when tx mode change" v1: https://patchwork.kernel.org/project/netdevbpf/cover/20240702040926.3327530… Changelog: v1 -> v2 - Instead of casting to bool, use !!

[PATCH net v1] net: wan: fsl_qmc_hdlc: Convert carrier_lock spinlock to a mutex

The carrier_lock spinlock protects the carrier detection. While it is hold, framer_get_status() is called witch in turn takes a mutex. This is not correct and can lead to a deadlock.

[PATCH 0/2] fix eMMC/SPI flash corruption when audio has been used on RK3399 Puma

by Quentin Schulz

In commit 91419ae0420f ("arm64: dts: rockchip: use BCLK to GPIO switch on rk3399"), an additional pinctrl state was added whose default pinmux is for 8ch i2s0. However, Puma only has 2ch i2s0. It's been overriding the pinctrl-0 property but the second property override was missed in the aforementioned commit. On Puma, a hardware slider called "BIOS Disable/Normal Boot" can disable eMMC and SPI to force booting from SD card. Another software-controlled GPIO is then configured to override this behavior to make eMMC and SPI available without human intervention. This is currently done in U-Boot and it was enough until the aforementioned commit. Indeed, because of this additional not-yet-overridden property, this software-controlled GPIO is now muxed in a state that does not override this hardware slider anymore, rendering SPI and eMMC flashes unusable. Let's override the property with the 2ch pinmux to fix this. While at it, add a GPIO hog for this software-controlled GPIO to make it explicit and also make it reserve the pin through the pinctrl subsystem to make sure nobody can mistakenly request it for something else: better have a non-working feature than eMMC/SPI being corrupted "randomly"!

[PATCH] OPP: Fix support for required OPPs for multiple PM domains

by Ulf Hansson

In _set_opp() we are normally bailing out when trying to set an OPP that is the current one. This make perfect sense, but becomes a problem when _set_required_opps() calls it recursively. More precisely, when a required OPP is being shared by multiple PM domains, we end up skipping to request the corresponding performance-state for all of the PM domains, but the first one. Let's fix the problem, by calling _set_opp_level() from _set_required_opps() instead.

[PATCH v4 0/2] ALSA: firewire-lib: restore process context workqueue to prevent deadlock

by Edmund Raile

This patchset serves to prevent an AB/BA deadlock: thread 0: * (lock A) acquire substream lock by snd_pcm_stream_lock_irq() in snd_pcm_status64() * (lock B) wait for tasklet to finish by calling tasklet_unlock_spin_wait() in tasklet_disable_in_atomic() in ohci_flush_iso_completions() of ohci.c thread 1: * (lock B) enter tasklet * (lock A) attempt to acquire substream lock, waiting for it to be released: snd_pcm_stream_lock_irqsave() in snd_pcm_period_elapsed() in update_pcm_pointers() in process_ctx_payloads() in process_rx_packets() of amdtp-stream.c ? tasklet_unlock_spin_wait </NMI> <TASK> ohci_flush_iso_completions firewire_ohci amdtp_domain_stream_pcm_pointer snd_firewire_lib snd_pcm_update_hw_ptr0 snd_pcm snd_pcm_status64 snd_pcm ? native_queued_spin_lock_slowpath </NMI> <IRQ> _raw_spin_lock_irqsave snd_pcm_period_elapsed snd_pcm process_rx_packets snd_firewire_lib irq_target_callback snd_firewire_lib handle_it_packet firewire_ohci context_tasklet firewire_ohci The issue has been reported as a regression of kernel 5.14: Link: https://lore.kernel.org/regressions/kwryofzdmjvzkuw6j3clftsxmoolynljztxqwg7… ("[REGRESSION] ALSA: firewire-lib: snd_pcm_period_elapsed deadlock with Fireface 800") Commit 7ba5ca32fe6e ("ALSA: firewire-lib: operate for period elapse event in process context") removed the process context workqueue from amdtp_domain_stream_pcm_pointer() and update_pcm_pointers() to remove its overhead. Commit b5b519965c4c ("ALSA: firewire-lib: obsolete workqueue for period update") belongs to the same patch series and removed the now-unused workqueue entirely. Though being observed on RME Fireface 800, this issue would affect all Firewire audio interfaces using ohci amdtp + pcm streaming. ALSA streaming, especially under intensive CPU load will reveal this issue the soonest due to issuing more hardIRQs, with time to occurrence ranging from 2 secons to 30 minutes after starting playback. to reproduce the issue: direct ALSA playback to the device: mpv --audio-device=alsa/sysdefault:CARD=Fireface800 Spor-Ignition.flac Time to occurrence: 2s to 30m Likelihood increased by: - high CPU load stress --cpu $(nproc) - switching between applications via workspaces tested with i915 in Xfce PulsaAudio / PipeWire conceal the issue as they run PCM substream without period wakeup mode, issuing less hardIRQs.

Unfortunately, in_serving_softirq() is > 0 even when the code is running in the hardirq or NMI context for hardirqs and NMIs that happened during a softirq. As a result, if a softirq handler contains a remote coverage collection section and a hardirq with another remote coverage collection section happens during handling the softirq, KCOV incorrectly detects a nested softirq coverate collection section and prints a WARNING, as reported by syzbot. This issue was exposed by commit a7f3813e589f ("usb: gadget: dummy_hcd: Switch to hrtimer transfer scheduler"), which switched dummy_hcd to using hrtimer and made the timer's callback be executed in the hardirq context. Change the related checks in KCOV to account for this behavior of in_serving_softirq() and make KCOV ignore remote coverage collection sections in the hardirq and NMI contexts. This prevents the WARNING printed by syzbot but does not fix the inability of KCOV to collect coverage from the __usb_hcd_giveback_urb when dummy_hcd is in use (caused by a7f3813e589f); a separate patch is required for that.

[PATCH v2] mm/hugetlb: fix hugetlb vs. core-mm PT locking

by David Hildenbrand

We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page table walking code in the codebase. Turns out that we missed one page table locking detail: page table locking for hugetlb folios that are not mapped using a single PMD/PUD. Assume we have hugetlb folio that spans multiple PTEs (e.g., 64 KiB hugetlb folios on arm64 with 4 KiB base page size). GUP, as it walks the page tables, will perform a pte_offset_map_lock() to grab the PTE table lock. However, hugetlb that concurrently modifies these page tables would actually grab the mm->page_table_lock: with USE_SPLIT_PTE_PTLOCKS, the locks would differ. Something similar can happen right now with hugetlb folios that span multiple PMDs when USE_SPLIT_PMD_PTLOCKS.

Add ptep_lockptr() to obtain the PTE page table lock using a pte pointer -- unfortunately we cannot convert pte_lockptr() because virt_to_page() doesn't work with kmap'ed page tables we can have with CONFIG_HIGHPTE. There is one ugly case: powerpc 8xx, whereby we have an 8 MiB hugetlb folio being mapped using two PTE page tables. While hugetlb wants to take the PMD table lock, core-mm would grab the PTE table lock of one of both PTE page tables. In such corner cases, we have to make sure that both locks match, which is (fortunately!) currently guaranteed for 8xx as it does not support SMP and consequently doesn't use split PT locks.

[to-be-updated] mm-let-pte_lockptr-consume-a-pte_t-pointer.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: let pte_lockptr() consume a pte_t pointer has been removed from the -mm tree. Its filename was mm-let-pte_lockptr-consume-a-pte_t-pointer.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm: let pte_lockptr() consume a pte_t pointer Date: Thu, 25 Jul 2024 20:39:54 +0200 Patch series "mm/hugetlb: fix hugetlb vs. core-mm PT locking". Working on another generic page table walker that tries to avoid special-casing hugetlb, I found a page table locking issue with hugetlb folios that are not mapped using a single PMD/PUD. For some hugetlb folio sizes, GUP will take different page table locks when walking the page tables than hugetlb when modifying the page tables. I did not actually try reproducing an issue, but looking at follow_pmd_mask() where we might be rereading a PMD value multiple times it's rather clear that concurrent modifications are rather unpleasant. In follow_page_pte() we might be better in that regard -- ptep_get() does a READ_ONCE() -- but who knows what else could happen concurrently in some weird corner cases (e.g., hugetlb folio getting unmapped and freed). This patch (of 2): pte_lockptr() is the only *_lockptr() function that doesn't consume what would be expected: it consumes a pmd_t pointer instead of a pte_t pointer. Let's change that. The two callers in pgtable-generic.c are easily adjusted. Adjust khugepaged.c:retract_page_tables() to simply do a pte_offset_map_nolock() to obtain the lock, even though we won't actually be traversing the page table. This makes the code more similar to the other variants and avoids other hacks to make the new pte_lockptr() version happy. pte_lockptr() users reside now only in pgtable-generic.c. Maybe, using pte_offset_map_nolock() is the right thing to do because the PTE table could have been removed in the meantime? At least it sounds more future proof if we ever have other means of page table reclaim. It's not quite clear if holding the PTE table lock is really required: what if someone else obtains the lock just after we unlock it? But we'll leave that as is for now, maybe there are good reasons. This is a preparation for adapting hugetlb page table locking logic to take the same locks as core-mm page table walkers would.

[PATCH v4 2/2] Revert "ALSA: firewire-lib: operate for period elapse event in process context"

[PATCH v2] fs/netfs/fscache_io: remove the obsolete "using_pgpriv2" flag

by Max Kellermann

This fixes a crash bug caused by commit ae678317b95e ("netfs: Remove deprecated use of PG_private_2 as a second writeback flag") by removing a leftover folio_end_private_2() call after all calls to folio_start_private_2() had been removed by the commit. By calling folio_end_private_2() without folio_start_private_2(), the folio refcounter breaks and causes trouble like RCU stalls and general protection faults.

[PATCH] fs/ceph/addr: pass using_pgpriv2=false to fscache_write_to_cache()

by Max Kellermann

This piece was missing in commit ae678317b95e ("netfs: Remove deprecated use of PG_private_2 as a second writeback flag"). There is one remaining use of PG_private_2: the function __fscache_clear_page_bits(), whose only purpose is to clear PG_private_2. This is done via folio_end_private_2() which also releases the folio reference which was supposed to be taken by folio_start_private_2() (via ceph_set_page_fscache()). __fscache_clear_page_bits() is called by __fscache_write_to_cache(), but only if the parameter using_pgpriv2 is true; the only caller of that function is ceph_fscache_write_to_cache() which still passes true. By calling folio_end_private_2() without folio_start_private_2(), the folio refcounter breaks and causes trouble like RCU stalls and general protection faults.

[PATCH] KVM: s390: fix validity interception issue when gisa is switched off

by Michael Mueller

The following validity interception occures when the gisa usage has been switched off either by using kernel parameter "kvm.use_gisa=0" or by setting the related sysfs attribute to N (echo N >/sys/module/kvm/ parameters/use_gisa). The issue surfaces in the host kernel with the following kernel message as soon a new kvm guest start has been attemted. kvm: unhandled validity intercept 0x1011 WARNING: CPU: 0 PID: 781237 at arch/s390/kvm/intercept.c:101 kvm_handle_sie_intercept+0x42e/0x4d0 [kvm] Modules linked in: vhost_net tap tun xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT xt_tcpudp nft_compat x_tables nf_nat_tftp nf_conntrack_tftp vfio_pci_core irqbypass vhost_vsock vmw_vsock_virtio_transport_common vsock vhost vhost_iotlb kvm nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 ip_set nf_tables sunrpc mlx5_ib ib_uverbs ib_core mlx5_core uvdevice s390_trng eadm_sch vfio_ccw zcrypt_cex4 mdev vfio_iommu_type1 vfio sch_fq_codel drm i2c_core loop drm_panel_orientation_quirks configfs nfnetlink lcs ctcm fsm dm_service_time ghash_s390 prng chacha_s390 libchacha aes_s390 des_s390 libdes sha3_512_s390 sha3_256_s390 sha512_s390 sha256_s390 sha1_s390 sha_common dm_mirror dm_region_hash dm_log zfcp scsi_transport_fc scsi_dh_rdac scsi_dh_emc scsi_dh_alua pkey zcrypt dm_multipath rng_core autofs4 [last unloaded: vfio_pci] CPU: 0 PID: 781237 Comm: CPU 0/KVM Not tainted 6.10.0-08682-gcad9f11498ea #6 Hardware name: IBM 3931 A01 701 (LPAR) Krnl PSW : 0704c00180000000 000003d93deb0122 (kvm_handle_sie_intercept+0x432/0x4d0 [kvm]) R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:3 CC:0 PM:0 RI:0 EA:3 Krnl GPRS: 000003d900000027 000003d900000023 0000000000000028 000002cd00000000 000002d063a00900 00000359c6daf708 00000000000bebb5 0000000000001eff 000002cfd82e9000 000002cfd80bc000 0000000000001011 000003d93deda412 000003ff8962df98 000003d93de77ce0 000003d93deb011e 00000359c6daf960 Krnl Code: 000003d93deb0112: c020fffe7259 larl %r2,000003d93de7e5c4 000003d93deb0118: c0e53fa8beac brasl %r14,000003d9bd3c7e70 #000003d93deb011e: af000000 mc 0,0 >000003d93deb0122: a728ffea lhi %r2,-22 000003d93deb0126: a7f4fe24 brc 15,000003d93deafd6e 000003d93deb012a: 9101f0b0 tm 176(%r15),1 000003d93deb012e: a774fe48 brc 7,000003d93deafdbe 000003d93deb0132: 40a0f0ae sth %r10,174(%r15) Call Trace: [<000003d93deb0122>] kvm_handle_sie_intercept+0x432/0x4d0 [kvm] ([<000003d93deb011e>] kvm_handle_sie_intercept+0x42e/0x4d0 [kvm]) [<000003d93deacc10>] vcpu_post_run+0x1d0/0x3b0 [kvm] [<000003d93deaceda>] __vcpu_run+0xea/0x2d0 [kvm] [<000003d93dead9da>] kvm_arch_vcpu_ioctl_run+0x16a/0x430 [kvm] [<000003d93de93ee0>] kvm_vcpu_ioctl+0x190/0x7c0 [kvm] [<000003d9bd728b4e>] vfs_ioctl+0x2e/0x70 [<000003d9bd72a092>] __s390x_sys_ioctl+0xc2/0xd0 [<000003d9be0e9222>] __do_syscall+0x1f2/0x2e0 [<000003d9be0f9a90>] system_call+0x70/0x98 Last Breaking-Event-Address: [<000003d9bd3c7f58>] __warn_printk+0xe8/0xf0 Cc: stable(a)vger.kernel.org Reported-by: Christian Borntraeger <borntraeger(a)linux.ibm.com> Closes: https://ibm-systems-z.slack.com/archives/C04BWBXSKEY/p1722280755665409 Fixes: fe0ef0030463 ("KVM: s390: sort out physical vs virtual pointers usage") Signed-off-by: Michael Mueller <mimu(a)linux.ibm.com> --- arch/s390/kvm/kvm-s390.h | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/s390/kvm/kvm-s390.h b/arch/s390/kvm/kvm-s390.h index bf8534218af3..e680c6bf0c9d 100644 --- a/arch/s390/kvm/kvm-s390.h +++ b/arch/s390/kvm/kvm-s390.h @@ -267,7 +267,12 @@ static inline unsigned long kvm_s390_get_gfn_end(struct kvm_memslots *slots) static inline u32 kvm_s390_get_gisa_desc(struct kvm *kvm) { - u32 gd = virt_to_phys(kvm->arch.gisa_int.origin); + u32 gd; + + if (!kvm->arch.gisa_int.origin) + return 0; + + gd = virt_to_phys(kvm->arch.gisa_int.origin); if (gd && sclp.has_gisaf) gd |= GISA_FORMAT1; -- 2.43.0

TIF_NOTIFY_SIGNAL will prevent the task from sleeping in do_freezer_trap(), and since the get_signal()'s relock loop doesn't retry task_work, the task will spin there not being able to sleep until the freezing is cancelled / the task is killed / etc. Run task_works in the freezer path. Keep the patch small and simple so it can be easily back ported, but we might need to do some cleaning after and look if there are other places with similar problems.

[PATCH 6.6] wifi: mac80211: track capability/opmode NSS separately

by Hauke Mehrtens

From: Johannes Berg <johannes.berg(a)intel.com> [ Upstream commit a8bca3e9371dc5e276af4168be099b2a05554c2a ] We're currently tracking rx_nss for each station, and that is meant to be initialized to the capability NSS and later reduced by the operating mode notification NSS. However, we're mixing up capabilities and operating mode NSS in the same variable. This forces us to recalculate the NSS capability on operating mode notification RX, which is a bit strange; due to the previous fix I had to never keep rx_nss as zero, it also means that the capa is never taken into account properly. Fix all this by storing the capability value, that can be recalculated unconditionally whenever needed, and storing the operating mode notification NSS separately, taking it into account when assigning the final rx_nss value.

The existing misuse in shrink_one() can cause ineffective protection of sub-trees that are grandchildren of root_mem_cgroup. Fix it by reusing lru_gen_age_node(), which already traverses the root_mem_cgroup tree, to calculate the protection. Previously lru_gen_age_node() opportunistically skips the first pass, i.e., when scan_control->priority is DEF_PRIORITY. On the second pass, lruvec_is_sizable() uses appropriate scan_control->priority, set by set_initial_priority() from lru_gen_shrink_node(), to decide whether a memcg is too small to reclaim from. Now lru_gen_age_node() unconditionally traverses the root_mem_cgroup tree. So it should call set_initial_priority() upfront, to make sure lruvec_is_sizable() uses appropriate scan_control->priority on the first pass. Otherwise, lruvec_is_reclaimable() can return false negatives and result in premature OOM kills when min_ttl_ms is used.

[PATCH 4.19 5.4 5.10 5.15 6.1 6.6] nilfs2: handle inconsistent state in nilfs_btnode_create_block()

by Ryusuke Konishi

commit 4811f7af6090e8f5a398fbdd766f903ef6c0d787 upstream. Syzbot reported that a buffer state inconsistency was detected in nilfs_btnode_create_block(), triggering a kernel bug. It is not appropriate to treat this inconsistency as a bug; it can occur if the argument block address (the buffer index of the newly created block) is a virtual block number and has been reallocated due to corruption of the bitmap used to manage its allocation state. So, modify nilfs_btnode_create_block() and its callers to treat it as a possible filesystem error, rather than triggering a kernel bug.

[PATCH] usb: gadget: u_serial: Set start_delayed during suspend

by Prashanth K

Upstream commit aba3a8d01d62 ("usb: gadget: u_serial: add suspend resume callbacks") added started_delayed flag, so that new ports which are opened after USB suspend can start IO while resuming. But if the port was already opened, and gadget suspend kicks in afterwards, start_delayed will never be set. This causes resume to bail out before calling gs_start_io(). Fix this by setting start_delayed during suspend.

[PATCH AUTOSEL 5.10 1/3] driver core: Make dev_err_probe() silent for -ENOMEM

by Sasha Levin

[PATCH AUTOSEL 6.10 1/3] block: don't call bio_uninit from bio_endio

by Sasha Levin

From: Christoph Hellwig <hch(a)lst.de> [ Upstream commit bf4c89fc8797f5c0964a0c3d561fbe7e8483b62f ] Commit b222dd2fdd53 ("block: call bio_uninit in bio_endio") added a call to bio_uninit in bio_endio to work around callers that use bio_init but fail to call bio_uninit after they are done to release the resources. While this is an abuse of the bio_init API we still have quite a few of those left. But this early uninit causes a problem for integrity data, as at least some users need the bio_integrity_payload. Right now the only one is the NVMe passthrough which archives this by adding a special case to skip the freeing if the BIP_INTEGRITY_USER flag is set. Sort this out by only putting bi_blkg in bio_endio as that is the cause of the actual leaks - the few users of the crypto context and integrity data all properly call bio_uninit, usually through bio_put for dynamically allocated bios.

[PATCH v2] drm/i915: Fix possible int overflow in skl_ddi_calculate_wrpll()

by Nikita Zhandarovich

On the off chance that clock value ends up being too high (by means of skl_ddi_calculate_wrpll() having benn called with big enough value of crtc_state->port_clock * 1000), one possible consequence may be that the result will not be able to fit into signed int. Fix this issue by moving conversion of clock parameter from kHz to Hz into the body of skl_ddi_calculate_wrpll(), as well as casting the same parameter to u64 type while calculating the value for AFE clock. This both mitigates the overflow problem and avoids possible erroneous integer promotion mishaps. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

[PATCH 5.15-stable] PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal

by Lukas Wunner

commit 11a1f4bc47362700fcbde717292158873fb847ed upstream. Keith reports a use-after-free when a DPC event occurs concurrently to hot-removal of the same portion of the hierarchy: The dpc_handler() awaits readiness of the secondary bus below the Downstream Port where the DPC event occurred. To do so, it polls the config space of the first child device on the secondary bus. If that child device is concurrently removed, accesses to its struct pci_dev cause the kernel to oops. That's because pci_bridge_wait_for_secondary_bus() neglects to hold a reference on the child device. Before v6.3, the function was only called on resume from system sleep or on runtime resume. Holding a reference wasn't necessary back then because the pciehp IRQ thread could never run concurrently. (On resume from system sleep, IRQs are not enabled until after the resume_noirq phase. And runtime resume is always awaited before a PCI device is removed.) However starting with v6.3, pci_bridge_wait_for_secondary_bus() is also called on a DPC event. Commit 53b54ad074de ("PCI/DPC: Await readiness of secondary bus after reset"), which introduced that, failed to appreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a reference on the child device because dpc_handler() and pciehp may indeed run concurrently. The commit was backported to v5.10+ stable kernels, so that's the oldest one affected. Add the missing reference acquisition.

For this, we transition from RBD_LOCK_STATE_LOCKED to RBD_LOCK_STATE_QUIESCING roughly for the duration of rbd_reacquire_lock() call. If the mapping is exclusive and I/O happens to arrive in this time window, it's failed with EROFS (later translated to EIO) based on the wrong assumption in rbd_img_exclusive_lock() -- "lock got released?" check there stopped making sense with commit a2b1da09793d ("rbd: lock should be quiesced on reacquire"). To make it worse, any such I/O is added to the acquiring list before EROFS is returned and this sets up for violating rbd_lock_del_request() precondition that the request is either on the running list or not on any list at all -- see commit ded080c86b3f ("rbd: don't move requests to the running list on errors"). rbd_lock_del_request() ends up processing these requests as if they were on the running list which screws up quiescing_wait completion counter and ultimately leads to rbd_assert(!completion_done(&rbd_dev->quiescing_wait)); being triggered on the next watch error.

For this, we transition from RBD_LOCK_STATE_LOCKED to RBD_LOCK_STATE_QUIESCING roughly for the duration of rbd_reacquire_lock() call.

The patch does not > apply to any recent kernel and AFAICT this issue has long since been > fixed. When fixing this bug, I didn't pay much attention to upstream changes. Upon reviewing the history of relevant commits, I found that they have been merged and reverted multiple times: ```bash git log -S 'cpumask_test_cpu(cpu, sched_domain_span(sd))' --oneline \ kernel/sched/fair.c 8aeaffef8c6e sched/fair: Take the scheduling domain into account in select_idle_smt() 3e6efe87cd5c sched/fair: Remove redundant check in select_idle_smt() 3e8c6c9aac42 sched/fair: Remove task_util from effective utilization in feec() c722f35b513f sched/fair: Bring back select_idle_smt(), but differently 6cd56ef1df39 sched/fair: Remove select_idle_smt() df3cb4ea1fb6 sched/fair: Fix wrong cpu selecting from isolated domain ``` The latest upstream commit 8aeaffef8c6e is not applicable to linux-4.19.y. The current patch has been tested on linux-4.19.y and I am looking forward to its inclusion in the stable version.

[PATCH 6.6-stable 1/2] PCI: Introduce cleanup helpers for device reference counts and locks

by Lukas Wunner

From: Ira Weiny <ira.weiny(a)intel.com> commit ced085ef369af7a2b6da962ec2fbd01339f60693 upstream. The "goto error" pattern is notorious for introducing subtle resource leaks. Use the new cleanup.h helpers for PCI device reference counts and locks. Similar to the new put_device() and device_lock() cleanup helpers, __free(put_device) and guard(device), define the same for PCI devices, __free(pci_dev_put) and guard(pci_dev). These helpers eliminate the need for "goto free;" and "goto unlock;" patterns. For example, A 'struct pci_dev *' instance declared as: struct pci_dev *pdev __free(pci_dev_put) = NULL; ...will automatically call pci_dev_put() if @pdev is non-NULL when @pdev goes out of scope (automatic variable scope). If a function wants to invoke pci_dev_put() on error, but return @pdev on success, it can do: return no_free_ptr(pdev); ...or: return_ptr(pdev); For potential cleanup opportunity there are 587 open-coded calls to pci_dev_put() in the kernel with 65 instances within 10 lines of a goto statement with the CXL driver threatening to add another one. The guard() helper holds the associated lock for the remainder of the current scope in which it was invoked. So, for example: func(...) { if (...) { ... guard(pci_dev); /* pci_dev_lock() invoked here */ ... } /* <- implied pci_dev_unlock() triggered here */ } There are 15 invocations of pci_dev_unlock() in the kernel with 5 instances within 10 lines of a goto statement. Again, the CXL driver is threatening to add another. Introduce these helpers to preclude the addition of new more error prone goto put; / goto unlock; sequences. For now, these helpers are used in drivers/cxl/pci.c to allow ACPI error reports to be fed back into the CXL driver associated with the PCI device identified in the report.

Bit-fields are not promoted to a 64-bit type, even if the underlying type is 64-bit, and so, if necessary, must be cast to a larger type when calculations are done. Fix a topa_entry->base address calculation by adding a cast. Without the cast, the address was limited to 36-bits i.e. 64GiB. The address calculation is used on systems that do not support Multiple Entry ToPA (only Broadwell), and affects physical addresses on or above 64GiB. Instead of writing to the correct address, the address comprising the first 36 bits would be written to. Intel PT snapshot and sampling modes are not affected.

There were multiple RSCNs indicating multiple devices were affected. Driver is in the process of finishing a fabric scan. A new RSCN (device up) arrived at the tail end of the last fabric scan. Driver mistakenly thinks the new RSCN is being taken care of by the previous fabric scan, where this notification is cleared and not acted on. The laser needs to be blinked again to get the device to show up. To prevent driver from accidentally clearing the RSCN notification, each RSCN is given a generation value. A fabric scan will scan for that generation(s). Any new RSCN arrive after the scan start will have a new generation value. This will trigger another scan to get latest data. The RSCN notification flag will be cleared when the scan is associate to that generation.

This is inconsistent since in most other places in the kernel, THP counters are explicitly separated for anon, shmem and file flavours. However, we are stuck with it since it constitutes a user ABI. Recently, commit 66f44583f9b6 ("mm: shmem: add mTHP counters for anonymous shmem") added equivalent mTHP stats for shmem, keeping the same "file_" prefix in the names. But in future, we may want to add extra stats to cover actual file pages, at which point, it would all become very confusing. So let's take the opportunity to rename these new counters "shmem_" before the change makes it upstream and the ABI becomes immutable. While we are at it, let's improve the documentation for the legacy counters to make it clear that they count shmem pages only.

This is inconsistent since in most other places in the kernel, THP counters are explicitly separated for anon, shmem and file flavours. However, we are stuck with it since it constitutes a user ABI. Recently, commit 66f44583f9b6 ("mm: shmem: add mTHP counters for anonymous shmem") added equivalent mTHP stats for shmem, keeping the same "file_" prefix in the names. But in future, we may want to add extra stats to cover actual file pages, at which point, it would all become very confusing. So let's take the opportunity to rename these new counters "shmem_" before the change makes it upstream and the ABI becomes immutable. While we are at it, let's improve the documentation for the legacy counters to make it clear that they count shmem pages only.

This is inconsistent since in most other places in the kernel, THP counters are explicitly separated for anon, shmem and file flavours. However, we are stuck with it since it constitutes a user ABI. Recently, commit 66f44583f9b6 ("mm: shmem: add mTHP counters for anonymous shmem") added equivalent mTHP stats for shmem, keeping the same "file_" prefix in the names. But in future, we may want to add extra stats to cover actual file pages, at which point, it would all become very confusing. So let's take the opportunity to rename these new counters "shmem_" before the change makes it upstream and the ABI becomes immutable. While we are at it, let's improve the documentation for the legacy counters to make it clear that they count shmem pages only.

Dirty throttling logic assumes dirty limits in page units fit into 32-bits. This patch series makes sure this is true (see patch 2/2 for more details). This patch (of 2): This reverts commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78. The commit is broken in several ways. Firstly, the removed (u64) cast from the multiplication will introduce a multiplication overflow on 32-bit archs if wb_thresh * bg_thresh >= 1<<32 (which is actually common - the default settings with 4GB of RAM will trigger this). Secondly, the div64_u64() is unnecessarily expensive on 32-bit archs. We have div64_ul() in case we want to be safe & cheap. Thirdly, if dirty thresholds are larger than 1<<32 pages, then dirty balancing is going to blow up in many other spectacular ways anyway so trying to fix one possible overflow is just moot.

Firstly, the removed (u64) cast from the multiplication will introduce a multiplication overflow on 32-bit archs if wb_thresh * bg_thresh >= 1<<32 (which is actually common - the default settings with 4GB of RAM will trigger this). Secondly, the div64_u64() is unnecessarily expensive on 32-bit archs. We have div64_ul() in case we want to be safe & cheap. Thirdly, if dirty thresholds are larger than 1<<32 pages, then dirty balancing is going to blow up in many other spectacular ways anyway so trying to fix one possible overflow is just moot.

[REGRESSION] No image on 4k display port displays connected through usb-c dock in kernel 6.10

by kevin＠holm.dev

Connecting two 4k displays with display port through a lenovo usb-c dock (type 40AS) to a Lenovo P14s Gen 2 (type 21A0) results in no image on the connected displays. The CPU in the Lenovo P14s is a 'AMD Ryzen 7 PRO 5850U with Radeon Graphics' and it has no discrete GPU. I first noticed the issue with kernel version '6.10.0-arch1-2' provided by arch linux. With the previous kernel version '6.9.10.arch1-1' both connected displays worked normally. I reported the issue in the arch forums at https://bbs.archlinux.org/viewtopic.php?id=297999 and was guided to do a bisection to find the commit that caused the problem. Through testing I identified that the issue is not present in the latest kernel directly compiled from the trovalds/linux git repository. With git bisect I identified 4df96ba66760345471a85ef7bb29e1cd4e956057 as the first bad commit and fa57924c76d995e87ca3533ec60d1d5e55769a27 as the first commit that fixed the problem again. The initial commit only still shows an image on one of the connected 4k screens. I have not investigated further to find out at what point both displays stopped showing an image. Best Regards, Kevin #regzbot introduced: 4df96ba66760345471a85ef7bb29e1cd4e956057

'-c' and '-S' both instruct the compiler to stop at different stages of the pipeline ('-S' after compiling, '-c' after assembling), so having them present together in the same command makes little sense. In this case, the test wants to stop before assembling because it is looking at the textual assembly output of the compiler for either '%fs' or '%gs', so remove '-c' from the list of arguments to resolve the error. All versions of GCC continue to work after this change, along with versions of clang that do or do not contain the change mentioned above.

[PATCH 5.15-stable 1/3] locking: Introduce __cleanup() based infrastructure

by Lukas Wunner

From: Peter Zijlstra <peterz(a)infradead.org> commit 54da6a0924311c7cf5015533991e44fb8eb12773 upstream. Use __attribute__((__cleanup__(func))) to build: - simple auto-release pointers using __free() - 'classes' with constructor and destructor semantics for scope-based resource management. - lock guards based on the above classes.

[PATCH 1/5] drm/ast: astdp: Wake up during connector status detection

by Thomas Zimmermann

Power up the ASTDP connector for connection status detection if the connector is not active. Keep it powered if a display is attached. This fixes a bug where the connector does not come back after disconnecting the display. The encoder's atomic_disable turns off power on the physical connector. Further HPD reads will fail, thus preventing the driver from detecting re-connected displays. For connectors that are actively used, only test the HPD flag without touching power.

[PATCH net 0/7] mptcp: fix inconsistent backup usage

by Matthieu Baerts (NGI0)

In all the MPTCP backup related tests, the backup flag was set on one side, and the expected behaviour is to have both sides respecting this decision. That's also the "natural" way, and what the users seem to expect. On the scheduler side, only the 'backup' field was checked, which is supposed to be set only if the other peer flagged a subflow as backup. But in various places, this flag was also set when the local host flagged the subflow as backup, certainly to have the expected behaviour mentioned above. Patch 1 modifies the packet scheduler to check if the backup flag has been set on both directions, not to change its behaviour after having applied the following patches. That's what the default packet scheduler should have done since the beginning in v5.7. Patch 2 fixes the backup flag being mirrored on the MPJ+SYN+ACK by accident since its introduction in v5.7. Instead, the received and sent backup flags are properly distinguished in requests. Patch 3 stops setting the received backup flag as well when sending an MP_PRIO, something that was done since the MP_PRIO support in v5.12. Patch 4 adds related and missing MIB counters to be able to easily check if MP_JOIN are sent with a backup flag. Certainly because these counters were not there, the behaviour that is fixed by patches here was not properly verified. Patch 5 validates the previous patch by extending the MPTCP Join selftest. Patch 6 fixes the backup support in signal endpoints: if a signal endpoint had the backup flag, it was not set in the MPJ+SYN+ACK as expected. It was only set for ongoing connections, but not future ones as expected, since the introduction of the backup flag in endpoints in v5.10. Patch 7 validates the previous patch by extending the MPTCP Join selftest as well.

[PATCH 6.1-stable 1/2] PCI: Introduce cleanup helpers for device reference counts and locks

by Lukas Wunner

From: Ira Weiny <ira.weiny(a)intel.com> commit ced085ef369af7a2b6da962ec2fbd01339f60693 upstream. The "goto error" pattern is notorious for introducing subtle resource leaks. Use the new cleanup.h helpers for PCI device reference counts and locks. Similar to the new put_device() and device_lock() cleanup helpers, __free(put_device) and guard(device), define the same for PCI devices, __free(pci_dev_put) and guard(pci_dev). These helpers eliminate the need for "goto free;" and "goto unlock;" patterns. For example, A 'struct pci_dev *' instance declared as: struct pci_dev *pdev __free(pci_dev_put) = NULL; ...will automatically call pci_dev_put() if @pdev is non-NULL when @pdev goes out of scope (automatic variable scope). If a function wants to invoke pci_dev_put() on error, but return @pdev on success, it can do: return no_free_ptr(pdev); ...or: return_ptr(pdev); For potential cleanup opportunity there are 587 open-coded calls to pci_dev_put() in the kernel with 65 instances within 10 lines of a goto statement with the CXL driver threatening to add another one. The guard() helper holds the associated lock for the remainder of the current scope in which it was invoked. So, for example: func(...) { if (...) { ... guard(pci_dev); /* pci_dev_lock() invoked here */ ... } /* <- implied pci_dev_unlock() triggered here */ } There are 15 invocations of pci_dev_unlock() in the kernel with 5 instances within 10 lines of a goto statement. Again, the CXL driver is threatening to add another. Introduce these helpers to preclude the addition of new more error prone goto put; / goto unlock; sequences. For now, these helpers are used in drivers/cxl/pci.c to allow ACPI error reports to be fed back into the CXL driver associated with the PCI device identified in the report.

[git:media_stage/fixes] media: ipu-bridge: fix ipu6 Kconfig dependencies
