2022-03-08KVM: x86/mmu: Drop RCU after processing each root in MMU notifier hooksSean Christopherson1-4/+4
Drop RCU protection after processing each root when handling MMU notifier hooks that aren't the "unmap" path, i.e. aren't zapping. Temporarily drop RCU to let RCU do its thing between roots, and to make it clear that there's no special behavior that relies on holding RCU across all roots. Currently, the RCU protection is completely superficial, it's necessary only to make rcu_dereference() of SPTE pointers happy. A future patch will rely on holding RCU as a proxy for vCPUs in the guest, e.g. to ensure shadow pages aren't freed before all vCPUs do a TLB flush (or rather, acknowledge the need for a flush), but in that case RCU needs to be held until the flush is complete if and only if the flush is needed because a shadow page may have been removed. And except for the "unmap" path, MMU notifier events cannot remove SPs (don't toggle PRESENT bit, and can't change the PFN for a SP).

2022-03-08KVM: x86/mmu: Check for !leaf=>leaf, not PFN change, in TDP MMU SP removalSean Christopherson1-2/+5
Look for a !leaf=>leaf conversion instead of a PFN change when checking if a SPTE change removed a TDP MMU shadow page. Convert the PFN check into a WARN, as KVM should never change the PFN of a shadow page (except when its being zapped or replaced). From a purely theoretical perspective, it's not illegal to replace a SP with a hugepage pointing at the same PFN. In practice, it's impossible as that would require mapping guest memory overtop a kernel-allocated SP. Either way, the check is odd.

2022-03-08KVM: x86/mmu: do not allow readers to acquire references to invalid rootsPaolo Bonzini1-4/+5
Remove the "shared" argument of for_each_tdp_mmu_root_yield_safe, thus ensuring that readers do not ever acquire a reference to an invalid root. After this patch, all readers except kvm_tdp_mmu_zap_invalidated_roots() treat refcount=0/valid, refcount=0/invalid and refcount=1/invalid in exactly the same way. kvm_tdp_mmu_zap_invalidated_roots() is different but it also does not acquire a reference to the invalid root, and it cannot see refcount=0/invalid because it is guaranteed to run after kvm_tdp_mmu_invalidate_all_roots(). Opportunistically add a lockdep assertion to the yield-safe iterator. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2022-03-08KVM: x86/mmu: only perform eager page splitting on valid rootsPaolo Bonzini1-1/+1
Eager page splitting is an optimization; it does not have to be performed on invalid roots.

Assert that mmu_lock is held for write by users of the yield-unfriendly TDP iterator. The nature of a shared walk means that the caller needs to play nice with other tasks modifying the page tables, which is more or less the same thing as playing nice with yielding. Theoretically, KVM could gain a flow where it could legitimately take mmu_lock for read in a non-preemptible context, but that's highly unlikely and any such case should be viewed with a fair amount of scrutiny.

2022-03-08KVM: x86/mmu: Document that zapping invalidated roots doesn't need to flushSean Christopherson2-8/+17
Remove the misleading flush "handling" when zapping invalidated TDP MMU roots, and document that flushing is unnecessary for all flavors of MMUs when zapping invalid/obsolete roots/pages. The "handling" in the TDP MMU is dead code, as zap_gfn_range() is called with shared=true, in which case it will never return true due to the flushing being handled by tdp_mmu_zap_spte_atomic(). No functional change intended.

2022-03-08KVM: x86/mmu: Formalize TDP MMU's (unintended?) deferred TLB flush logicSean Christopherson2-1/+17
Explicitly ignore the result of zap_gfn_range() when putting the last reference to a TDP MMU root, and add a pile of comments to formalize the TDP MMU's behavior of deferring TLB flushes to alloc/reuse. Note, this only affects the !shared case, as zap_gfn_range() subtly never returns true for "flush" as the flush is handled by tdp_mmu_zap_spte_atomic(). Putting the root without a flush is ok because even if there are stale references to the root in the TLB, they are unreachable because KVM will not run the guest with the same ASID without first flushing (where ASID in this context refers to both SVM's explicit ASID and Intel's implicit ASID that is constructed from VPID+PCID+EPT4A+etc...).

2022-03-08KVM: x86/mmu: Fix wrong/misleading comments in TDP MMU fast zapSean Christopherson2-21/+33
Fix misleading and arguably wrong comments in the TDP MMU's fast zap flow. The comments, and the fact that actually zapping invalid roots was added separately, strongly suggests that zapping invalid roots is an optimization and not required for correctness. That is a lie. KVM _must_ zap invalid roots before returning from kvm_mmu_zap_all_fast(), because when it's called from kvm_mmu_invalidate_zap_pages_in_memslot(), KVM is relying on it to fully remove all references to the memslot. Once the memslot is gone, KVM's mmu_notifier hooks will be unable to find the stale references as the hva=>gfn translation is done via the memslots. If KVM doesn't immediately zap SPTEs and userspace unmaps a range after deleting a memslot, KVM will fail to zap in response to the mmu_notifier due to not finding a memslot corresponding to the notifier's range, which leads to a variation of use-after-free. The other misleading comment (and code) explicitly states that roots without a reference should be skipped. While that's technically true, it's also extremely misleading as it should be impossible for KVM to encounter a defunct root on the list while holding mmu_lock for write. Opportunistically add a WARN to enforce that invariant.

This isn't strictly required for correctness, as setting the dirty bit in a defunct SPTE will not change the SPTE from !PRESENT to PRESENT.

This reverts commit 878aed8db324bec64f3c3f956e64d5ae7375a5de. This change breaks existing setups where conntrack is used with asymmetric paths. In these cases, the NAT transformation occurs on the syn-ack instead of the syn: 1. SYN x:12345 -> y -> 443 // sent by initiator, receiverd by responder 2. SYNACK y:443 -> x:12345 // First packet seen by conntrack, as sent by responder 3. tuple_force_port_remap() gets called, sees: 'tcp from 443 to port 12345 NAT' -> pick a new source port, inititor receives 4. SYNACK y:$RANDOM -> x:12345 // connection is never established While its possible to avoid the breakage with NOTRACK rules, a kernel update should not break working setups. An alternative to the revert is to augment conntrack to tag mid-stream connections plus more code in the nat core to skip NAT for such connections, however, this leads to more interaction/integration between conntrack and NAT. Therefore, revert, users will need to add explicit nat rules to avoid port shadowing.

Add combined sequence mode supported by Tegra QSPI controller. For commands which contain cmd, addr, data parts to it, controller can accept all 3 transfers at once and avoid interrupt for each transfer. This would improve read & write performance.

The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path. And it will cause refcount leak in error paths. Fix this by calling of_node_put() in error handling too.
