AKASHI Takahiro abbfed9ed1 arm64: ptrace: add PTRACE_SET_SYSCALL ... Note: This patch is from v6 of Takahiro's proposed "arm64: add seccomp support" patchset (leecam@google.com) To allow tracer to be able to change/skip a system call by re-writing a syscall number, there are several approaches: (1) modify x8 register with ptrace(PTRACE_SETREGSET), and handle this case later on in syscall_trace_enter(), or (2) support ptrace(PTRACE_SET_SYSCALL) as on arm Thinking of the fact that user_pt_regs doesn't expose 'syscallno' to tracer as well as that secure_computing() expects a changed syscall number to be visible, especially case of -1, before this function returns in syscall_trace_enter(), we'd better take (2).
