Please backport 980a573621ea to 6.12, 6.14

by Dionna Amalie Glaze

980a573621ea ("tpm: Make chip->{status,cancel,req_canceled} opt") This is a dependent commit for the series of patches to add the AMD SEV-SNP SVSM vTPM device driver. Kernel 6.11 added SVSM support, but not support for the critical component for boot integrity that follows the SEV-SNP threat model. That series https://lore.kernel.org/all/20250410135118.133240-1-sgarzare@redhat.com/ is applied at tip but is not yet in the mainline. I have confirmed that this patch applies cleanly. Stefano's patch series needs a minor tweak to the first patch due to the changed surrounding function declarations in arch/x86/include/asm/sev.h https://github.com/deeglaze/amdese-linux/commits/vtpm612/ I've independently tested the patches. -- -Dionna Glaze, PhD, CISSP, CCSP (she/her)

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

[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 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).

[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.

[to-be-updated] mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending has been removed from the -mm tree. Its filename was mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Jens Axboe <axboe(a)kernel.dk> Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending Date: Wed, 23 Apr 2025 17:37:06 -0600 userfaultfd may use interruptible sleeps to wait on userspace filling a page fault, which works fine if the task can be reliably put to sleeping waiting for that. However, if the task has a normal (ie non-fatal) signal pending, then TASK_INTERRUPTIBLE sleep will simply cause schedule() to be a no-op. For a task that registers a page with userfaultfd and then proceeds to do a write from it, if that task also has a signal pending then it'll essentially busy loop from do_page_fault() -> handle_userfault() until that fault has been filled. Normally it'd be expected that the task would sleep until that happens. Here's a trace from an application doing just that: handle_userfault+0x4b8/0xa00 (P) hugetlb_fault+0xe24/0x1060 handle_mm_fault+0x2bc/0x318 do_page_fault+0x1e8/0x6f0 do_translation_fault+0x9c/0xd0 do_mem_abort+0x44/0xa0 el1_abort+0x3c/0x68 el1h_64_sync_handler+0xd4/0x100 el1h_64_sync+0x6c/0x70 fault_in_readable+0x74/0x108 (P) iomap_file_buffered_write+0x14c/0x438 blkdev_write_iter+0x1a8/0x340 vfs_write+0x20c/0x348 ksys_write+0x64/0x108 __arm64_sys_write+0x1c/0x38 where the task is looping with 100% CPU time in the above mentioned fault path. Since it's impossible to handle signals, or other conditions like TIF_NOTIFY_SIGNAL that also prevents interruptible sleeping, from the fault path, use TASK_UNINTERRUPTIBLE with a short timeout even for vmf modes that would normally ask for INTERRUPTIBLE or KILLABLE sleep.

+ mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.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: Jens Axboe <axboe(a)kernel.dk> Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending Date: Wed, 23 Apr 2025 17:37:06 -0600 userfaultfd may use interruptible sleeps to wait on userspace filling a page fault, which works fine if the task can be reliably put to sleeping waiting for that. However, if the task has a normal (ie non-fatal) signal pending, then TASK_INTERRUPTIBLE sleep will simply cause schedule() to be a no-op. For a task that registers a page with userfaultfd and then proceeds to do a write from it, if that task also has a signal pending then it'll essentially busy loop from do_page_fault() -> handle_userfault() until that fault has been filled. Normally it'd be expected that the task would sleep until that happens. Here's a trace from an application doing just that: handle_userfault+0x4b8/0xa00 (P) hugetlb_fault+0xe24/0x1060 handle_mm_fault+0x2bc/0x318 do_page_fault+0x1e8/0x6f0 do_translation_fault+0x9c/0xd0 do_mem_abort+0x44/0xa0 el1_abort+0x3c/0x68 el1h_64_sync_handler+0xd4/0x100 el1h_64_sync+0x6c/0x70 fault_in_readable+0x74/0x108 (P) iomap_file_buffered_write+0x14c/0x438 blkdev_write_iter+0x1a8/0x340 vfs_write+0x20c/0x348 ksys_write+0x64/0x108 __arm64_sys_write+0x1c/0x38 where the task is looping with 100% CPU time in the above mentioned fault path. Since it's impossible to handle signals, or other conditions like TIF_NOTIFY_SIGNAL that also prevents interruptible sleeping, from the fault path, use TASK_UNINTERRUPTIBLE with a short timeout even for vmf modes that would normally ask for INTERRUPTIBLE or KILLABLE sleep. Fatal signals will still be handled by the caller, and the timeout is short enough to hopefully not cause any issues. If this is the first invocation of this fault, eg FAULT_FLAG_TRIED isn't set, then the normal sleep mode is used.
