Doing debugfs creation after vm creation leaves things in a quasi-initialized state for a while. This is further complicated by the fact that we tear down debugfs from kvm_destroy_vm(). Align debugfs and stats init/destroy with the vm init/destroy pattern to avoid any headaches. Note the fix for a benign mistake in error handling for calls to kvm_arch_create_vm_debugfs() rolled in. Since all implementations of the function return 0 unconditionally it isn't actually a bug at the moment. Lastly, tear down debugfs/stats data in the kvm_create_vm_debugfs() error path. Previously it was safe to assume that kvm_destroy_vm() would take out the garbage, that is no longer the case. Signed-off-by:

At the time the VM fd is used in kvm_create_vm_debugfs(), the fd has been allocated but not yet installed. It is only really useful as an identifier in strings for the VM (such as debugfs). Treat it exactly as such by passing the string name of the fd to kvm_create_vm_debugfs(), futureproofing against possible misuse of the VM fd. Suggested-by:

Add compile-time and init-time sanity checks to ensure that the MMIO SPTE mask doesn't overlap the MMIO SPTE generation or the MMU-present bit. The generation currently avoids using bit 63, but that's as much coincidence as it is strictly necessarly. That will change in the future, as TDX support will require setting bit 63 (SUPPRESS_VE) in the mask. Explicitly carve out the bits that are allowed in the mask so that any future shuffling of SPTE bits doesn't silently break MMIO caching (KVM has broken MMIO caching more than once due to overlapping the generation with other things).

Rename the tracepoint function from trace_kvm_async_pf_doublefault() to trace_kvm_async_pf_repeated_fault() to make it clear, since double fault has nothing to do with this trace function. Asynchronous Page Fault (APF) is an artifact generated by KVM when it cannot find a physical page to satisfy an EPT violation. KVM uses APF to tell the guest OS to do something else such as scheduling other guest processes to make forward progress. However, when another guest process also touches a previously APFed page, KVM halts the vCPU instead of generating a repeated APF to avoid wasting cycles. Double fault (#DF) clearly has a different meaning and a different consequence when triggered. #DF requires two nested contributory exceptions instead of two page faults faulting at the same address. A prevous bug on APF indicates that it may trigger a double fault in the guest [1] and clearly this trace function has nothing to do with it. So rename this function should be a valid choice. No functional change intended. [1] https://www.spinics.net/lists/kvm/msg214957.htmlSigned-off-by:

Stop Xen timer (if it's running) prior to changing the IRQ vector and potentially (re)starting the timer. Changing the IRQ vector while the timer is still running can result in KVM injecting a garbage event, e.g. vm_xen_inject_timer_irqs() could see a non-zero xen.timer_pending from a previous timer but inject the new xen.timer_virq.

Disable SEV-ES if MMIO caching is disabled as SEV-ES relies on MMIO SPTEs generating #NPF(RSVD), which are reflected by the CPU into the guest as a #VC. With SEV-ES, the untrusted host, a.k.a. KVM, doesn't have access to the guest instruction stream or register state and so can't directly emulate in response to a #NPF on an emulated MMIO GPA. Disabling MMIO caching means guest accesses to emulated MMIO ranges cause #NPF(!PRESENT), and those flavors of #NPF cause automatic VM-Exits, not #VC. Adjust KVM's MMIO masks to account for the C-bit location prior to doing SEV(-ES) setup, and document that dependency between adjusting the MMIO SPTE mask and SEV(-ES) setup.

Fully re-evaluate whether or not MMIO caching can be enabled when SPTE masks change; simply clearing enable_mmio_caching when a configuration isn't compatible with caching fails to handle the scenario where the masks are updated, e.g. by VMX for EPT or by SVM to account for the C-bit location, and toggle compatibility from false=>true. Snapshot the original module param so that re-evaluating MMIO caching preserves userspace's desire to allow caching. Use a snapshot approach so that enable_mmio_caching still reflects KVM's actual behavior. Fixes: 8b9e74bf ("KVM: x86/mmu: Use enable_mmio_caching to track if MMIO caching is enabled") Reported-by:

The emulator mishandles LEA with register source operand. Even though such LEA is illegal, it can be encoded and fed to CPU. In which case real hardware throws #UD.

kvm_fixup_and_inject_pf_error() was introduced to fixup the error code( e.g., to add RSVD flag) and inject the #PF to the guest, when guest MAXPHYADDR is smaller than the host one. When it comes to nested, L0 is expected to intercept and fix up the #PF and then inject to L2 directly if - L2.MAXPHYADDR < L0.MAXPHYADDR and - L1 has no intention to intercept L2's #PF (e.g., L2 and L1 have the same MAXPHYADDR value && L1 is using EPT for L2), instead of constructing a #PF VM Exit to L1. Currently, with PFEC_MASK and PFEC_MATCH both set to 0 in vmcs02, the interception and injection may happen on all L2 #PFs. However, failing to initialize 'fault' in kvm_fixup_and_inject_pf_error() may cause the fault.async_page_fault being NOT zeroed, and later the #PF being treated as a nested async page fault, and then being injected to L1. Instead of zeroing 'fault' at the beginning of this function, we mannually set the value of 'fault.async_page_fault', because false is the value we really expect.

This cause an incorrect cache hit if the guest modifies the steal time address while the memslots remain the same. This can happen with kexec, in which case the preempted bit is written at the address used by the old kernel instead of the old one.

If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. * tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (50 commits) rv: Unlock on error path in rv_unregister_reactor() tracing: Use alignof__(struct {type b;}) instead of offsetof() tracing/eprobe: Show syntax error logs in error_log file scripts/tracing: Fix typo 'the the' in comment tracepoints: It is CONFIG_TRACEPOINTS not CONFIG_TRACEPOINT tracing: Use free_trace_buffer() in allocate_trace_buffers() tracing: Use a struct alignof to determine trace event field alignment rv/reactor: Add the panic reactor rv/reactor: Add the printk reactor rv/monitor: Add the wwnr monitor rv/monitor: Add the wip monitor rv/monitor: Add the wip monitor skeleton created by dot2k Documentation/rv: Add deterministic automata instrumentation documentation Documentation/rv: Add deterministic automata monitor synthesis documentation tools/rv: Add dot2k Documentation/rv: Add deterministic automaton documentation tools/rv: Add dot2c Documentation/rv: Add a basic documentation rv/include: Add instrumentation helper functions rv/include: Add deterministic automata monitor definition via C macros ...

Pull xfs updates from Darrick Wong: "The biggest changes for this release are the log scalability improvements, lockless lookups for the buffer cache, and making the attr fork a permanent part of the incore inode in preparation for directory parent pointers. There's also a bunch of bug fixes that have accumulated since -rc5. I might send you a second pull request with some more bug fixes that I'm still working on. Once the merge window ends, I will hand maintainership back to Dave Chinner until the 6.1-rc1 release so that I can conduct the design review for the online fsck feature, and try to get it merged. Summary: - Improve scalability of the XFS log by removing spinlocks and global synchronization points. - Add security labels to whiteout inodes to match the other filesystems. - Clean up per-ag pointer passing to simplify call sites. - Reduce verifier overhead by precalculating more AG geometry. - Implement fast-path lockless lookups in the buffer cache to reduce spinlock hammering. - Make attr forks a permanent part of the inode structure to fix a UAF bug and because most files these days tend to have security labels and soon will have parent pointers too. - Clean up XFS_IFORK_Q usage and give it a better name. - Fix more UAF bugs in the xattr code. - SOB my tags. - Fix some typos in the timestamp range documentation. - Fix a few more memory leaks. - Code cleanups and typo fixes. - Fix an unlocked inode fork pointer access in getbmap" * tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (61 commits) xfs: delete extra space and tab in blank line xfs: fix NULL pointer dereference in xfs_getbmap() xfs: Fix typo 'the the' in comment xfs: Fix comment typo xfs: don't leak memory when attr fork loading fails xfs: fix for variable set but not used warning xfs: xfs_buf cache destroy isn't RCU safe xfs: delete unnecessary NULL checks xfs: fix comment for start time value of inode with bigtime enabled xfs: fix use-after-free in xattr node block inactivation xfs: lockless buffer lookup xfs: remove a superflous hash lookup when inserting new buffers xfs: reduce the number of atomic when locking a buffer after lookup xfs: merge xfs_buf_find() and xfs_buf_get_map() xfs: break up xfs_buf_find() into individual pieces xfs: add in-memory iunlink log item xfs: add log item precommit operation xfs: combine iunlink inode update functions xfs: clean up xfs_iunlink_update_inode() xfs: double link the unlinked inode list ... -
