[PATCH OLK-5.10] KVM: x86/mmu: Don't advance iterator after restart due to yielding
by Liu Shixin 21 Mar '24

21 Mar '24

From: Sean Christopherson <seanjc(a)google.com> mainline inclusion from mainline-v5.16-rc7 commit 3a0f64de479cae75effb630a2e0a237ca0d0623c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95REM CVE: CVE-2021-47094 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- After dropping mmu_lock in the TDP MMU, restart the iterator during tdp_iter_next() and do not advance the iterator. Advancing the iterator results in skipping the top-level SPTE and all its children, which is fatal if any of the skipped SPTEs were not visited before yielding. When zapping all SPTEs, i.e. when min_level == root_level, restarting the iter and then invoking tdp_iter_next() is always fatal if the current gfn has as a valid SPTE, as advancing the iterator results in try_step_side() skipping the current gfn, which wasn't visited before yielding. Sprinkle WARNs on iter->yielded being true in various helpers that are often used in conjunction with yielding, and tag the helper with __must_check to reduce the probabily of improper usage. Failing to zap a top-level SPTE manifests in one of two ways. If a valid SPTE is skipped by both kvm_tdp_mmu_zap_all() and kvm_tdp_mmu_put_root(), the shadow page will be leaked and KVM will WARN accordingly.

This directly triggers a WARN due to encountering a page with page_count() == 0, but it can also lead to data corruption and additional errors in the kernel.

But with respect to leaking shadow pages, the bug was introduced by yielding before processing the current gfn. Alternatively, tdp_mmu_iter_cond_resched() could simply fall through, or callers could jump to their "retry" label. The downside of that approach is that tdp_mmu_iter_cond_resched() _must_ be called before anything else in the loop, and there's no easy way to enfornce that requirement. Ideally, KVM would handling the cond_resched() fully within the iterator macro (the code is actually quite clean) and avoid this entire class of bugs, but that is extremely difficult do while also supporting yielding after tdp_mmu_set_spte_atomic() fails. Yielding after failing to set a SPTE is very desirable as the "owner" of the REMOVED_SPTE isn't strictly bounded, e.g. if it's zapping a high-level shadow page, the REMOVED_SPTE may block operations on the SPTE for a significant amount of time.

[PATCH OLK-5.10] net/sched: act_ct: fix skb leak and crash on ooo frags
by Zhengchao Shao 21 Mar '24

21 Mar '24

From: Tao Liu <taoliu828(a)163.com> mainline inclusion from mainline-v6.8-rc1 commit 3f14b377d01d8357eba032b4cabc8c1149b458b6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JTC CVE: CVE-2023-52610 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- act_ct adds skb->users before defragmentation. If frags arrive in order, the last frag's reference is reset in: inet_frag_reasm_prepare skb_morph which is not straightforward. However when frags arrive out of order, nobody unref the last frag, and all frags are leaked. The situation is even worse, as initiating packet capture can lead to a crash[0] when skb has been cloned and shared at the same time. Fix the issue by removing skb_get() before defragmentation. act_ct returns TC_ACT_CONSUMED when defrag failed or in progress.
