Kees Cook a39caac02f selftests/seccomp: powerpc: Set syscall return during ptrace syscall exit ... Some archs (like powerpc) only support changing the return code during syscall exit when ptrace is used. Test entry vs exit phases for which portions of the syscall number and return values need to be set at which different phases. For non-powerpc, all changes are made during ptrace syscall entry, as before. For powerpc, the syscall number is changed at ptrace syscall entry and the syscall return value is changed on ptrace syscall exit.
