Bjorn Andersson authored
The introduction of high resolution PWM support changed the order of the operations in the calculation of min and max period. The result in both divisions is in most cases a truncation to 0, which limits the period to the range of [0, 0]. Both numerators (and denominators) are within 64 bits, so the whole expression can be put directly into the div64_u64, instead of doing it partially.

Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during APIC map construction to hunt for TOCTOU bugs in KVM. KVM's optimized map recalc makes multiple passes over the list of vCPUs, and the calculations ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where toggling LAPIC_MODE_DISABLED is quite interesting.

Bail from kvm_recalculate_phys_map() and disable the optimized map if the target vCPU's x2APIC ID is out-of-bounds, i.e. if the vCPU was added and/or enabled its local APIC after the map was allocated. This fixes an out-of-bounds access bug in the !x2apic_format path where KVM would write beyond the end of phys_map. Check the x2APIC ID regardless of whether or not x2APIC is enabled, as KVM's hardcodes x2APIC ID to be the vCPU ID, i.e. it can't change, and the map allocation in kvm_recalculate_apic_map() doesn't check for x2APIC being enabled, i.e. the check won't get false postivies. Note, this also affects the x2apic_format path, which previously just ignored the "x2apic_id > new->max_apic_id" case. That too is arguably a bug fix, as ignoring the vCPU meant that KVM would not send interrupts to the vCPU until the next map recalculation. In practice, that "bug" is likely benign as a newly present vCPU/APIC would immediately trigger a recalc. But, there's no functional downside to disabling the map, and a future patch will gracefully handle the -E2BIG case by retrying instead of simply disabling the optimized map. Opportunistically add a sanity check on the xAPIC ID size, along with a comment explaining why the xAPIC ID is guaranteed to be "good".

Increment vcpu->stat.exits when handling a fastpath VM-Exit without going through any part of the "slow" path. Not bumping the exits stat can result in wildly misleading exit counts, e.g. if the primary reason the guest is exiting is to program the TSC deadline timer.

While testing Hyper-V enabled Windows Server 2019 guests on Zen4 hardware I noticed that with vCPU count large enough (> 16) they sometimes froze at boot. With vCPU count of 64 they never booted successfully - suggesting some kind of a race condition. Since adding "vnmi=0" module parameter made these guests boot successfully it was clear that the problem is most likely (v)NMI-related. Running kvm-unit-tests quickly showed failing NMI-related tests cases, like "multiple nmi" and "pending nmi" from apic-split, x2apic and xapic tests and the NMI parts of eventinj test. The issue was that once one NMI was being serviced no other NMI was allowed to be set pending (NMI limit = 0), which was traced to svm_is_vnmi_pending() wrongly testing for the "NMI blocked" flag rather than for the "NMI pending" flag. Fix this by testing for the right flag in svm_is_vnmi_pending(). Once this is done, the NMI-related kvm-unit-tests pass successfully and the Windows guest no longer freezes at boot.

Factor in the address space (non-SMM vs. SMM) of the target shadow page when recovering potential NX huge pages, otherwise KVM will retrieve the wrong memslot when zapping shadow pages that were created for SMM. The bug most visibly manifests as a WARN on the memslot being non-NULL, but the worst case scenario is that KVM could unaccount the shadow page without ensuring KVM won't install a huge page, i.e. if the non-SMM slot is being dirty logged, but the SMM slot is not. ------------[ cut here ]------------ WARNING: CPU: 1 PID: 3911 at arch/x86/kvm/mmu/mmu.c:7015 kvm_nx_huge_page_recovery_worker+0x38c/0x3d0 [kvm] CPU: 1 PID: 3911 Comm: kvm-nx-lpage-re RIP: 0010:kvm_nx_huge_page_recovery_worker+0x38c/0x3d0 [kvm] RSP: 0018:ffff99b284f0be68 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff99b284edd000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 RBP: ffff9271397024e0 R08: 0000000000000000 R09: ffff927139702450 R10: 0000000000000000 R11: 0000000000000001 R12: ffff99b284f0be98 R13: 0000000000000000 R14: ffff9270991fcd80 R15: 0000000000000003 FS: 0000000000000000(0000) GS:ffff927f9f640000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f0aacad3ae0 CR3: 000000088fc2c005 CR4: 00000000003726e0 Call Trace: <TASK> __pfx_kvm_nx_huge_page_recovery_worker+0x10/0x10 [kvm] kvm_vm_worker_thread+0x106/0x1c0 [kvm] kthread+0xd9/0x100 ret_from_fork+0x2c/0x50 </TASK> ---[ end trace 0000000000000000 ]--- This bug was exposed by commit edbdb43f ("KVM: x86: Preserve TDP MMU roots until they are explicitly invalidated"), which allowed KVM to retain SMM TDP MMU roots effectively indefinitely. Before commit edbdb43f, KVM would zap all SMM TDP MMU roots and thus all SMM TDP MMU shadow pages once all vCPUs exited SMM, which made the window where this bug (recovering an SMM NX huge page) could be encountered quite tiny. To hit the bug, the NX recovery thread would have to run while at least one vCPU was in SMM. Most VMs typically only use SMM during boot, and so the problematic shadow pages were gone by the time the NX recovery thread ran. Now that KVM preserves TDP MMU roots until they are explicitly invalidated (e.g. by a memslot deletion), the window to trigger the bug is effectively never closed because most VMMs don't delete memslots after boot (except for a handful of special scenarios).

This reverts commit 32c08693. The reverted commit was intended to remove a dead check however it was observed that this check was actually being used to exit early instead of looping sbi->s_mb_max_to_scan times when we are able to find a free extent bigger than the goal extent. Due to this, a my performance tests (fsmark, parallel file writes in a highly fragmented FS) were seeing a 2x-3x regression. Example, the default value of the following variables is: sbi->s_mb_max_to_scan = 200 sbi->s_mb_min_to_scan = 10 In ext4_mb_check_limits() if we find an extent smaller than goal, then we return early and try again. This loop will go on until we have processed sbi->s_mb_max_to_scan(=200) number of free extents at which point we exit and just use whatever we have even if it is smaller than goal extent. Now, the regression comes when we find an extent bigger than goal. Earlier, in this case we would loop only sbi->s_mb_min_to_scan(=10) times and then just use the bigger extent. However with commit 32c08693 that check was removed and hence we would loop sbi->s_mb_max_to_scan(=200) times even though we have a big enough free extent to satisfy the request. The only time we would exit early would be when the free extent is *exactly* the size of our goal, which is pretty uncommon occurrence and so we would almost always end up looping 200 times. Hence, revert the commit by adding the check back to fix the regression. Also add a comment to outline this policy.

huge_ptep_get must be reimplemented in order to go through all the PTEs of a NAPOT region: this is needed because the HW can update the A/D bits of any of the PTE that constitutes the NAPOT region.

We need to avoid inconsistencies across the PTEs that form a NAPOT region, so when we write protect such a region, we should clear and flush all the PTEs to make sure that any of those PTEs is not cached which would result in such inconsistencies (arm64 does the same).

While implementing support for in-kernel decompression in kmod, finit_module() was returning a very suspicious value: finit_module(3, "", MODULE_INIT_COMPRESSED_FILE) = 18446744072717407296 It turns out the check for module_get_next_page() failing is wrong, and hence the decompression was not really taking place. Invert the condition to fix it.

When switching from kthreads to vhost_tasks two bugs were added: 1. The vhost worker tasks's now show up as processes so scripts doing ps or ps a would not incorrectly detect the vhost task as another process. 2. kthreads disabled freeze by setting PF_NOFREEZE, but vhost tasks's didn't disable or add support for them. To fix both bugs, this switches the vhost task to be thread in the process that does the VHOST_SET_OWNER ioctl, and has vhost_worker call get_signal to support SIGKILL/SIGSTOP and freeze signals. Note that SIGKILL/STOP support is required because CLONE_THREAD requires CLONE_SIGHAND which requires those 2 signals to be supported. This is a modified version of the patch written by Mike Christie <michael.christie@oracle.com> which was a modified version of patch originally written by Linus. Much of what depended upon PF_IO_WORKER now depends on PF_USER_WORKER. Including ignoring signals, setting up the register state, and having get_signal return instead of calling do_group_exit. Tidied up the vhost_task abstraction so that the definition of vhost_task only needs to be visible inside of vhost_task.c. Making it easier to review the code and tell what needs to be done where. As part of this the main loop has been moved from vhost_worker into vhost_task_fn. vhost_worker now returns true if work was done. The main loop has been updated to call get_signal which handles SIGSTOP, freezing, and collects the message that tells the thread to exit as part of process exit. This collection clears __fatal_signal_pending. This collection is not guaranteed to clear signal_pending() so clear that explicitly so the schedule() sleeps. For now the vhost thread continues to exist and run work until the last file descriptor is closed and the release function is called as part of freeing struct file. To avoid hangs in the coredump rendezvous and when killing threads in a multi-threaded exec. The coredump code and de_thread have been modified to ignore vhost threads. Remvoing the special case for exec appears to require teaching vhost_dev_flush how to directly complete transactions in case the vhost thread is no longer running. Removing the special case for coredump rendezvous requires either the above fix needed for exec or moving the coredump rendezvous into get_signal.

The Linux Kernel currently only requires make v3.82 while the grouped target functionality requires make v4.3. Removed the grouped target introduced in 4ce1f694 ("selinux: ensure av_permissions.h is built when needed") as well as the multiple header file targets in the make rule. This effectively reverts the problem commit. We will revisit this change when make >= 4.3 is required by the rest of the kernel.
