| * | executor, sys/linux, pkg: enable syzos for riscv64 | 6eanut | 2026-02-25 | 1 | -0/+56 |
| | | | | | | | | | | | | | | | | | | | | | This patch enables syzos for riscv64 and implements the corresponding pseudo syscalls. Pseudo syscalls: - syz_kvm_setup_syzos_vm - syz_kvm_add_vcpu - syz_kvm_assert_syzos_uexit Syzos guest support: - guest_uexit - guest_execute_code - guest_handle_csrr and guest_handle_csrw Test seeds: - riscv64-syz_kvm_setup_syzos_vm - riscv64-syz_kvm_setup_syzos_vm-csrr - riscv64-syz_kvm_setup_syzos_vm-csrw | ||||
| * | executor, sys/linux, pkg: enable syz_kvm_assert_reg for riscv64 | 6eanut | 2026-01-21 | 1 | -0/+2 |
| | | | | | | | | - Enables syz_kvm_assert_reg for riscv64. - Updates kvm_one_reg according to the latest definition in https://github.com/torvalds/linux/blob/master/arch/riscv/include/uapi/asm/kvm.h. - Adds a test case: riscv64-kvm-reg. | ||||
| * | executor, sys/linux, pkg: enable syz_kvm_setup_cpu for riscv64 | 6eanut | 2026-01-20 | 1 | -0/+19 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements syz_kvm_setup_cpu for riscv64 architecture. The pseudo-syscall accepts VM fd, vCPU fd, host memory, and guest code as parameters. Additional parameters (ntext, flags, opts, nopt) are included for interface consistency with other architectures but are currently unused on riscv64. Implementation: - Set up guest memory via KVM_SET_USER_MEMORY_REGION - Copy guest code to guest memory - Initialize guest registers to enable code execution in S-mode - Return 0 on success, -1 on failure Testing: A test file syz_kvm_setup_cpu_riscv64 is included in sys/linux/test/ to verify basic functionality. Known limitations: - ifuzz is not yet compatible with riscv64. Temporary workaround: set text[riscv64] to TextTarget and return nil in createTargetIfuzzConfig for riscv64 to ensure generateText and mutateText work correctly. This patch also adds support for KVM_GET_ONE_REG ioctl. | ||||
