[PATCH v5 3/3] KVM: x86: Add x2APIC "features" to control EOI broadcast suppression

by Khushit Shah

Add two flags for KVM_CAP_X2APIC_API to allow userspace to control support for Suppress EOI Broadcasts, which KVM completely mishandles. When x2APIC support was first added, KVM incorrectly advertised and "enabled" Suppress EOI Broadcast, without fully supporting the I/O APIC side of the equation, i.e. without adding directed EOI to KVM's in-kernel I/O APIC. That flaw was carried over to split IRQCHIP support, i.e. KVM advertised support for Suppress EOI Broadcasts irrespective of whether or not the userspace I/O APIC implementation supported directed EOIs. Even worse, KVM didn't actually suppress EOI broadcasts, i.e. userspace VMMs without support for directed EOI came to rely on the "spurious" broadcasts. KVM "fixed" the in-kernel I/O APIC implementation by completely disabling support for Suppress EOI Broadcasts in commit 0bcc3fb95b97 ("KVM: lapic: stop advertising DIRECTED_EOI when in-kernel IOAPIC is in use"), but didn't do anything to remedy userspace I/O APIC implementations. KVM's bogus handling of Suppress EOI Broadcast is problematic when the guest relies on interrupts being masked in the I/O APIC until well after the initial local APIC EOI. E.g. Windows with Credential Guard enabled handles interrupts in the following order: 1. Interrupt for L2 arrives. 2. L1 APIC EOIs the interrupt. 3. L1 resumes L2 and injects the interrupt. 4. L2 EOIs after servicing. 5. L1 performs the I/O APIC EOI. Because KVM EOIs the I/O APIC at step #2, the guest can get an interrupt storm, e.g. if the IRQ line is still asserted and userspace reacts to the EOI by re-injecting the IRQ, because the guest doesn't de-assert the line until step #4, and doesn't expect the interrupt to be re-enabled until step #5. Unfortunately, simply "fixing" the bug isn't an option, as KVM has no way of knowing if the userspace I/O APIC supports directed EOIs, i.e. suppressing EOI broadcasts would result in interrupts being stuck masked in the userspace I/O APIC due to step #5 being ignored by userspace. And fully disabling support for Suppress EOI Broadcast is also undesirable, as picking up the fix would require a guest reboot, *and* more importantly would change the virtual CPU model exposed to the guest without any buy-in from userspace. Add KVM_X2APIC_ENABLE_SUPPRESS_EOI_BROADCAST and KVM_X2APIC_DISABLE_SUPPRESS_EOI_BROADCAST flags to allow userspace to explicitly enable or disable support for Suppress EOI Broadcasts. This gives userspace control over the virtual CPU model exposed to the guest, as KVM should never have enabled support for Suppress EOI Broadcast without userspace opt-in. Not setting either flag will result in legacy quirky behavior for backward compatibility. When KVM_X2APIC_ENABLE_SUPPRESS_EOI_BROADCAST is set and using in-kernel IRQCHIP mode, KVM will use I/O APIC version 0x20, which includes support for the EOI Register. Note, Suppress EOI Broadcasts is defined only in Intel's SDM, not in AMD's APM. But the bit is writable on some AMD CPUs, e.g. Turin, and KVM's ABI is to support Directed EOI (KVM's name) irrespective of guest CPU vendor.

[5.10] regression: virtual consoles 2-12 unusable

by Ben Hutchings

Hello stable maintainers, Several Debian users reported a regression after updating to kernel version 5.10.247. Commit f0982400648a ("fbdev: Add bounds checking in bit_putcs to fix vmalloc-out-of-bounds"), a backport of upstream commit 3637d34b35b2, depends on vc_data::vc_font.charcount being initialised correctly. However, before commit a1ac250a82a5 ("fbcon: Avoid using FNTCHARCNT() and hard-coded built-in font charcount") in 5.11, this member was set to 256 for VTs initially created with a built-in font and 0 for VTs initially created with a user font. Since Debian normally sets a user font before creating VTs 2 and up, those additional VTs became unusable. VT 1 also doesn't work correctly if the user font has > 256 characters, and the bounds check is ineffective if it has < 256 characters. This can be fixed by backporting the following commits from 5.11: 7a089ec7d77f console: Delete unused con_font_copy() callback implementations 259a252c1f4e console: Delete dummy con_font_set() and con_font_default() callback implementations 4ee573086bd8 Fonts: Add charcount field to font_desc 4497364e5f61 parisc/sticore: Avoid hard-coding built-in font charcount a1ac250a82a5 fbcon: Avoid using FNTCHARCNT() and hard-coded built-in font charcount These all apply without fuzz and builds cleanly for x86_64 and parisc64. I tested on x86_64 that: - VT 2 works again - bit_putcs_aligned() is setting charcnt = 256 - After loading a font with 512 characters, bit_putcs_aligned() sets charcnt = 512 and is able to display characters at positions >= 256 Ben. -- Ben Hutchings Man invented language to satisfy his deep need to complain. - Lily Tomlin

[PATCH 0/7] clk: qcom: gcc: Do not turn off PCIe GDSCs during gdsc_disable()

by Krishna Chaitanya Chundru

With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This can happen during scenarios such as system suspend and breaks the resume of PCIe controllers from suspend. So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs during gdsc_disable() and allow the hardware to transition the GDSCs to retention when the parent domain enters low power state during system suspend.

[PATCH v3] drm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind

by Osama Abdelkader

Fix several issues in dw_dp_bind() error handling: 1. Missing return after drm_bridge_attach() failure - the function continued execution instead of returning an error. 2. Resource leak: drm_dp_aux_register() is not a devm function, so drm_dp_aux_unregister() must be called on all error paths after aux registration succeeds. This affects errors from: - drm_bridge_attach() - phy_init() - devm_add_action_or_reset() - platform_get_irq() - devm_request_threaded_irq() 3. Bug fix: platform_get_irq() returns the IRQ number or a negative error code, but the error path was returning ERR_PTR(ret) instead of ERR_PTR(dp->irq).

If you do that subtitution and work it all out, you end up with: \Sum w_i * (v_i - v0) avg = --------------------- + v0 \Sum w_i Since you cannot very well track a ratio like that (and not suffer terrible numerical problems) we simpy track the numerator and denominator individually and only perform the division when strictly needed. Notably, the numerator lives in cfs_rq->avg_vruntime and the denominator lives in cfs_rq->avg_load. The one extra 'funny' is that these numbers track the entities in the tree, and current is typically outside of the tree, so avg_vruntime() adds current when needed before doing the division. (vruntime_eligible() elides the division by cross-wise multiplication) Anyway, as mentioned above, we currently use the CFS era min_vruntime for this purpose. However, this thing can only move forward, while the above avg can in fact move backward (when a non-eligible task leaves, the average becomes smaller), this can cause trouble when through happenstance (or construction) these values drift far enough apart to wreck the game. Replace cfs_rq::min_vruntime with cfs_rq::zero_vruntime which is kept near/at avg_vruntime, following its motion. The down-side is that this requires computing the avg more often.

[PATCH 0/3] fs: add immutable rootfs and support pivot_root() in the initramfs

by Christian Brauner

Currently pivot_root() doesnt't work on the real rootfs because it cannot be unmounted. Userspace has to do a recursive removal of the initramfs contents manually before continuing the boot. Really all we want from the real rootfs is to serve as the parent mount for anything that is actually useful such as the tmpfs or ramfs for initramfs unpacking or the rootfs itself. There's no need for the real rootfs to actually be anything meaningful or useful. Add a immutable rootfs that can be selected via the "immutable_rootfs" kernel command line option. The kernel will mount a tmpfs/ramfs on top of it, unpack the initramfs and fire up userspace which mounts the rootfs and can then just do: chdir(rootfs); pivot_root(".", "."); umount2(".", MNT_DETACH); and be done with it. (Ofc, userspace can also choose to retain the initramfs contents by using something like pivot_root(".", "/initramfs") without unmounting it.) Technically this also means that the rootfs mount in unprivileged namespaces doesn't need to become MNT_LOCKED anymore as it's guaranteed that the immutable rootfs remains permanently empty so there cannot be anything revealed by unmounting the covering mount. In the future this will also allow us to create completely empty mount namespaces without risking to leak anything. systemd already handles this all correctly as it tries to pivot_root() first and falls back to MS_MOVE only when that fails. This goes back to various discussion in previous years and a LPC 2024 presentation about this very topic.

[PATCH 5.10,5.15,6.1,6.6 RESEND] leds: spi-byte: Initialize device node before access

by Tiffany Yang

Commit 7f9ab862e05c ("leds: spi-byte: Call of_node_put() on error path") was merged in 6.11 and then backported to stable trees through 5.10. It relocates the line that initializes the variable 'child' to a later point in spi_byte_probe(). Versions < 6.9 do not have commit ccc35ff2fd29 ("leds: spi-byte: Use devm_led_classdev_register_ext()"), which removes a line that reads a property from 'child' before its new initialization point. Consequently, spi_byte_probe() reads from an uninitialized device node in stable kernels 6.6-5.10. Initialize 'child' before it is first accessed. Fixes: 7f9ab862e05c ("leds: spi-byte: Call of_node_put() on error path") Signed-off-by: Tiffany Yang <ynaffit(a)google.com> --- As an alternative to moving the initialization of 'child' up, Fedor Pchelkin proposed [1] backporting the change that removes the intermediate access.

[PATCH 3/4] ASoC: codecs: wsa884x: fix codec initialisation

by Johan Hovold

The soundwire update_status() callback may be called multiple times with the same ATTACHED status but initialisation should only be done when transitioning from UNATTACHED to ATTACHED. Fix the inverted hw_init flag which was set to false instead of true after initialisation which defeats its purpose and may result in repeated unnecessary initialisation. Similarly, the initial state of the flag was also inverted so that the codec would only be initialised and brought out of regmap cache only mode if its status first transitions to UNATTACHED.

ba1b40ed0e34bab597fd90d4c4e9f7397f878c8f for 6.18.y

by Miguel Ojeda

Hi Greg, Sasha, Please consider commit ba1b40ed0e34 ("drm: nova: depend on CONFIG_64BIT") for 6.18.y. It should cherry-pick cleanly. Without this commit, one can create a config where `CONFIG_DRM_NOVA` selects `CONFIG_NOVA_CORE` without satisfying its `CONFIG_64BIT` dependency. In turn, this means arm32 builds can fail -- Kconfig warns: WARNING: unmet direct dependencies detected for NOVA_CORE Depends on [n]: HAS_IOMEM [=y] && 64BIT && PCI [=y] && RUST [=y] && RUST_FW_LOADER_ABSTRACTIONS [=y] Selected by [y]: - DRM_NOVA [=y] && HAS_IOMEM [=y] && DRM [=y]=y [=y] && PCI [=y] && RUST [=y] And then the build fails with (among others, see the related commit 5c5a41a75452 ("gpu: nova-core: depend on CONFIG_64BIT") for more): error[E0308]: mismatched types --> drivers/gpu/nova-core/fb.rs:50:59 | 50 | hal::fb_hal(chipset).write_sysmem_flush_page(bar, page.dma_handle())?; | ----------------------- ^^^^^^^^^^^^^^^^^ expected `u64`, found `u32` | | | arguments to this method are incorrect | Cc'ing Danilo and Alexandre so that they can confirm they agree. Thanks! Cheers, Miguel

Please add 127b90315ca0 ("sched/proxy: Yield the donor task") to 6.12.y / 6.18.y

by Holger Hoffstätte

Hi - a Gentoo user recently found that 6.18.2 started to reproducuibly crash when building their go toolchain [1]. Apparently the addition of "sched/fair: Forfeit vruntime on yield" (mainline 79104becf42b) can result in the infamous NULL returned from pick_eevdf(), which is not supposed to happen. It turned out that the mentioned commit triggered a bug related to the recently added proxy execution feature, which was already fixed in mainline by "sched/proxy: Yield the donor task" (127b90315ca0), though not marked for stable. Applying this to 6.18.2/.3-rc1 (and probably 6.12 as well) has reproducibly fixed the problem. A possible reason the crash was triggered by the Go runtime could be its specific use of yield(), though that's just speculation on my part. So please add 127b90315ca0 ("sched/proxy: Yield the donor task") to 6.18.y/6.12.y. I know we're already in 6.18.3-rc1, but the crasher seems reproducible. Fernand, please correct me if I got the explanations wrong. Thanks! Holger [1] https://bugs.gentoo.org/968116 starting at #8

[PATCH v2] gpio: mpsse: fix reference leak in gpio_mpsse_probe() error paths

[PATCH 6.6.y 0/4] perf/x86/amd: add LBR capture support outside of hardware events

by Leon Hwang

Hi all, This backport wires up AMD perfmon v2 so BPF and other software clients can snapshot LBR stacks on demand, similar to the Intel support upstream. The series keeps the LBR-freeze path branchless, adds the perf_snapshot_branch_stack callback for AMD, and drops the sampling-only restriction now that snapshots can be taken from software contexts.

Sd card race on resume with filesystem errors (possible data loss?)

by Sergio Callegari

Hi and happy new year! I would like to report a problem that I am encountering with the sdcard storage. I have a laptop/convertible where /home is on an sd-card (because the internal disk is too small). The card is luks encrypted and has a btrfs filesystem on it. When the laptop sleeps and then resumes, there is a race. The sdcard gets accessed for read/write but is not yet ready, so there are I/O errors. BTRFS is not happy with them and tends to remount RO. This issue is well known to purism developers (e.g. see https://source.puri.sm/Librem5/linux/-/issues/484 and https://forums.puri.sm/t/sdcard-becomes-read-only-after-waking-up-from-susp…). My kernel logs are identical to those in https://source.puri.sm/Librem5/linux/-/issues/484 (first comment), apart from the fact that I get the errors from BTRFS, while the reporter there gets the errors from EXT4. This indicates that the race is not specific to BTRFS. The errors in the kernel logs come right after the PM: suspend exit message. From what I understand: 1. The error is more frequent with the SD-LUKS-FILESYSTEM stratification, but not specific to it 2. A phone/tablet set up such as those that purism developers address will generally use sdcard for storage and require suspend, being a good trigger for the problem. However, the problem is in no means specific to phones, ARM devices, etc. I am getting it on an X86-64 laptop. 3. It is unclear to me if there is a real risk of data loss. Possibly with BTRFS that has a more complex data management this can be the case. 4.Even without data loss, the issue requires a reboot to get the filesystem back to RW, so it is annoying. 5. Purism developers have a kernel patch for it at https://source.puri.sm/Librem5/linux/-/merge_requests/788, but I believe it is not in linux mainline or stable. Would it make sense to consider that patch? 6. For stable kernels, there is a mitigation consisting in a systemd sleep-resume hook as in #!/bin/sh /usr/bin/systemd-cat -p5 /usr/bin/echo ${1} ${2} case "${1}" in post) sleep 1.5 systemd-cat -p4 /usr/bin/echo "hack, wait for sdcard" ;; esac see https://source.puri.sm/Librem5/linux/-/issues/484#note_277648 This appears to reduce the occurrence of the problem, but not to eliminate it completely. Thanks for the attention Sergio

[PATCH v2] gfs2: Fix use-after-free in gfs2_fill_super()

by Ryota Sakamoto

The issue occurs when gfs2_freeze_lock_shared() fails in gfs2_fill_super(). If !sb_rdonly(sb), threads for the quotad and logd were started, however, in the error path for gfs2_freeze_lock_shared(), the threads are not stopped by gfs2_destroy_threads() before jumping to fail_per_node. Introduce fail_threads to handle stopping the threads if the threads were started.

[PATCH] nouveau: don't attempt fwsec on sb on newer platforms.

by Dave Airlie

From: Dave Airlie <airlied(a)redhat.com> The changes to always loads fwsec sb causes problems on newer GPUs which don't use this path. Add hooks and pass through the device specific layers.
