[PATCH v1 1/3] x86/tdx: Check for TDX partitioning during early TDX init

by Jeremi Piotrowski

Check for additional CPUID bits to identify TDX guests running with Trust Domain (TD) partitioning enabled. TD partitioning is like nested virtualization inside the Trust Domain so there is a L1 TD VM(M) and there can be L2 TD VM(s). In this arrangement we are not guaranteed that the TDX_CPUID_LEAF_ID is visible to Linux running as an L2 TD VM. This is because a majority of TDX facilities are controlled by the L1 VMM and the L2 TDX guest needs to use TD partitioning aware mechanisms for what's left. So currently such guests do not have X86_FEATURE_TDX_GUEST set. We want the kernel to have X86_FEATURE_TDX_GUEST set for all TDX guests so we need to check these additional CPUID bits, but we skip further initialization in the function as we aren't guaranteed access to TDX module calls.

[PATCH v3 1/1] lib/vsprintf: Fix %pfwf when current node refcount == 0

by Herve Codina

A refcount issue can appeared in __fwnode_link_del() due to the pr_debug() call: WARNING: CPU: 0 PID: 901 at lib/refcount.c:25 refcount_warn_saturate+0xe5/0x110 Call Trace: <TASK> ... of_node_get+0x1e/0x30 of_fwnode_get+0x28/0x40 fwnode_full_name_string+0x34/0x90 fwnode_string+0xdb/0x140 ... vsnprintf+0x17b/0x630 ... __fwnode_link_del+0x25/0xa0 fwnode_links_purge+0x39/0xb0 of_node_release+0xd9/0x180 ... Indeed, an fwnode (of_node) is being destroyed and so, of_node_release() is called because the of_node refcount reached 0. From of_node_release() several function calls are done and lead to a pr_debug() calls with %pfwf to print the fwnode full name. The issue is not present if we change %pfwf to %pfwP. To print the full name, %pfwf iterates over the current node and its parents and obtain/drop a reference to all nodes involved. In order to allow to print the full name (%pfwf) of a node while it is being destroyed, do not obtain/drop a reference to this current node.

[REGRESSION]: nouveau: Asynchronous wait on fence

by Owen T. Heisler

#regzbot introduced: d386a4b54607cf6f76e23815c2c9a3abc1d66882 #regzbot link: https://gitlab.freedesktop.org/drm/nouveau/-/issues/180 ## Problem 1. Connect external display to DVI port on dock and run X with both displays in use. 2. Wait hours or days. 3. Suddenly the secondary Nvidia-connected display turns off and X stops responding to keyboard/mouse input. In *some* cases it is possible to switch to a virtual TTY with Ctrl+Alt+Fn and log in there. In any case, shutdown/reboot after this happens is *usually* not successful (forced power-off is required). This started happening after the upgrade to Debian bullseye, and the problem remains with Debian bookworm. ## Reproducing Unfortunately I have not found a way to reliably reproduce this bug. An affected kernel version will crash infrequently, perhaps monthly with "regular workstation use". With the more recent v6.1 kernels the crash seems to occur more frequently, perhaps within two days, if the out-of-tree acpi-call module (Debian's [acpi-call-dkms](https://packages.debian.org/acpi-call-dkms) package) is installed. For the logs below that are from tainted kernels, that out-of-tree module is why. The latest crash with the same `Asynchronous wait on fence` error occured on Debian stock linux-image-6.1.0-13-amd64 v6.1.55-1 with /proc/sys/kernel/tainted == 0. I have failed to trigger this crash by using 3D acceleration, [Piglit](https://piglit.freedesktop.org/) tests, or other stress tests. ## Errors Common log errors (see more log data [below](#user-content-logs)): - `Asynchronous wait on fence nouveau:systemd-logind` - `RIP: 0010:gf119_head_state+0xdd/0x110 [nouveau]` - `nouveau 0000:01:00.0: timer: stalled at ffffffffffffffff` (or `tmr: stalled at ffffffffffffffff`) - `Fixing recursive fault but reboot is needed!` ## Kernel versions At least mainline, v6.1, v5.15, v5.10, v5.4, and v4.19 series all seem to be affected by this bug. Here are the results of testing various specific revisions: - v6.1.51 bad - v5.15.130 bad - v5.14-rc6-2-g6eaa1f3c59a7 good - v5.10.194 bad - v5.4.256 bad - v4.19.294 bad - v4.19.289 bad - v4.19.255 bad - v4.19.234-18-gd60f27d6ff8a bad - v4.19.232 bad - v4.19.205-27-gd386a4b54607 bad - v4.19.205-26-ga78f93b9bba1 good - v4.19.205 good - v4.19.200 good - v4.19.180 good The `git bisect` result from this: ``` d386a4b54607cf6f76e23815c2c9a3abc1d66882 is the first bad commit ``` ## Kernel configuration and compilation Various minimal kernel configs have not exhibited the bug, so I am testing with a Debian stock config as follows. This applies to all tests. - Start with the stock config from Debian `linux-image-4.19.0-18-amd64_4.19.208-1` at <https://gitlab.freedesktop.org/drm/nouveau/uploads/9c0a82bc8a80b368c2cc38d2…> - make olddefconfig - make clean - scripts/config --disable DEBUG_INFO \ --set-str LOCALVERSION -$mylocalversion \ --enable LOCALVERSION_AUTO \ --set-str SYSTEM_TRUSTED_KEYS '' - make -j$(nproc --all) bindeb-pkg ## Kernel boot parameters The `nouveau.config=NvClkMode=15` parameter is in use for all tests. Omitting this parameter does not seem to change the behavior. ## Hardware - ThinkPad W530 - Dock with Nvidia-connected DVI ports - Secondary display connected via DVI - Nvidia Optimus GPU switching system $ lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K2000M] (rev a1) ## Logs Here is some log data I have been able to capture. dmesg output from Debian bullseye with current nouveau-next commit 9622bcb7c72b230d64b7f7d2f9505e17214f3597. The `Asynchronous wait on fence` happened approximately when the display turned off.

[PATCH] MIPS: kernel: Clear FPU states when setting up kernel threads

by Thomas Bogendoerfer

io_uring sets up the io worker kernel thread via a syscall out of an user space prrocess. This process might have used FPU and since copy_thread() didn't clear FPU states for kernel threads a BUG() is triggered for using FPU inside kernel. Move code around to always clear FPU state for user and kernel threads.

The race scenario thus could be this: CPU 29: CPU 16: perf_event_release_kernel --> mutex_lock(&ctx->mutex) --> perf_remove_from_context --> perf_group_detach(event); for_each_sibling_event() --> list_del_init(&event->sibling_list) As commit f3c0eba287049（“perf: Add a few assertions”）said: “Notable for_each_sibling_event() relies on exclusion from modification. This would normally be holding either ctx->lock or ctx->mutex, however due to how things are constructed disabling IRQs is a valid and sufficient substitute for ctx->lock.”, we think it's necessary to hold ctx ->mutex, but currently LTS such as 4.19,5.4,5.10, and 6.1 all does not do so: perf_event_task --> perf_iterate_sb --> perf_iterate_sb_cpu --> event_filter_match --> pmu_filter_match --> for_each_sibling_event commit bd27568117664（“perf: Rewrite core context handling”）had removed the pmu_filter_match operation, so it may be a temporary workaround for this issue. But it's necessary to confirm if there is a race problem between sibling_list, and if it is, how to fix currently LTS branches. Thanks in advance.
