Merge tag 'seccomp-v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull seccomp updates from Kees Cook: "The bulk of the changes are with the seccomp selftests to accommodate some powerpc-specific behavioral characteristics. Additional cleanups, fixes, and improvements are also included: - heavily refactor seccomp selftests (and clone3 selftests dependency) to fix powerpc (Kees Cook, Thadeu Lima de Souza Cascardo) - fix style issue in selftests (Zou Wei) - upgrade "unknown action" from KILL_THREAD to KILL_PROCESS (Rich Felker) - replace task_pt_regs(current) with current_pt_regs() (Denis Efremov) - fix corner-case race in USER_NOTIF (Jann Horn) - make CONFIG_SECCOMP no longer per-arch (YiFei Zhu)" * tag 'seccomp-v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (23 commits) seccomp: Make duplicate listener detection non-racy seccomp: Move config option SECCOMP to arch/Kconfig selftests/clone3: Avoid OS-defined clone_args selftests/seccomp: powerpc: Set syscall return during ptrace syscall exit selftests/seccomp: Allow syscall nr and ret value to be set separately selftests/seccomp: Record syscall during ptrace entry selftests/seccomp: powerpc: Fix seccomp return value testing selftests/seccomp: Remove SYSCALL_NUM_RET_SHARE_REG in favor of SYSCALL_RET_SET selftests/seccomp: Avoid redundant register flushes selftests/seccomp: Convert REGSET calls into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Convert HAVE_GETREG into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Remove syscall setting #ifdefs selftests/seccomp: mips: Remove O32-specific macro selftests/seccomp: arm64: Define SYSCALL_NUM_SET macro selftests/seccomp: arm: Define SYSCALL_NUM_SET macro selftests/seccomp: mips: Define SYSCALL_NUM_SET macro selftests/seccomp: Provide generic syscall setting macro selftests/seccomp: Refactor arch register macros to avoid xtensa special case selftests/seccomp: Use __NR_mknodat instead of __NR_mknod selftests/seccomp: Use bitwise instead of arithmetic operator for flags ...

- bool "Enable seccomp to safely compute untrusted bytecode"
- depends on PROC_FS
- default y
- help
- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via /proc/<pid>/seccomp, it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.
-
- If unsure, say Y. Only embedded should say N here.
