2024-11-05riscv: kvm: Fix out-of-bounds array accessBjörn Töpel
In kvm_riscv_vcpu_sbi_init() the entry->ext_idx can contain an out-of-bound index. This is used as a special marker for the base extensions, that cannot be disabled. However, when traversing the extensions, that special marker is not checked prior indexing the array. Add an out-of-bounds check to the function.

2024-10-27firewire: core: fix invalid port index for parent deviceTakashi Sakamoto
In a commit 24b7f8e5cd65 ("firewire: core: use helper functions for self ID sequence"), the enumeration over self ID sequence was refactored with some helper functions with KUnit tests. These helper functions are guaranteed to work expectedly by the KUnit tests, however their application includes a mistake to assign invalid value to the index of port connected to parent device. This bug affects the case that any extra node devices which has three or more ports are connected to 1394 OHCI controller. In the case, the path to update the tree cache could hits WARN_ON(), and gets general protection fault due to the access to invalid address computed by the invalid value. This commit fixes the bug to assign correct port index.

2024-10-25Merge branch 'kvm-no-struct-page' into HEADPaolo Bonzini
TL;DR: Eliminate KVM's long-standing (and heinous) behavior of essentially guessing which pfns are refcounted pages (see kvm_pfn_to_refcounted_page()). Getting there requires "fixing" arch code that isn't obviously broken. Specifically, to get rid of kvm_pfn_to_refcounted_page(), KVM needs to stop marking pages/folios dirty/accessed based solely on the pfn that's stored in KVM's stage-2 page tables. Instead of tracking which SPTEs correspond to refcounted pages, simply remove all of the code that operates on "struct page" based ona the pfn in stage-2 PTEs. This is the back ~40-50% of the series. For x86 in particular, which sets accessed/dirty status when that info would be "lost", e.g. when SPTEs are zapped or KVM clears the dirty flag in a SPTE, foregoing the updates provides very measurable performance improvements for related operations. E.g. when clearing dirty bits as part of dirty logging, and zapping SPTEs to reconstitue huge pages when disabling dirty logging. The front ~40% of the series is cleanups and prep work, and most of it is x86 focused (purely because x86 added the most special cases, *sigh*). E.g. several of the inputs to hva_to_pfn() (and it's myriad wrappers), can be removed by cleaning up and deduplicating x86 code. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
