Remember to lock user pmap in pmap_extract() pmap_extract() has to lock user pmap to prevent concurrent pruning of the page table. The kernel pmap is exempt from this because it uses a fixed page table structure. |

vmm(4): add limit to number of vcpus After fixing previous syzbot issues related to lock contention, the reproducer code managed to hit an issue where it can exhaust kernel memory by allocating vcpus. Since each vcpu (regardless if it's SVM or VMX-capable) requires wiring some number of pages of memory, it was possible to starve other parts of the kernel. This change limits the total number of vcpus to 512, a conservative number given vmm(4) only supports single vcpu guests at the moment. ok mlarkin@ |
