    seccomp: Use -1 marker for end of mode 1 syscall list · fe4bfff8
    Kees Cook authored
    The terminator for the mode 1 syscalls list was a 0, but that could be
    a valid syscall number (e.g. x86_64 __NR_read). By luck, __NR_read was
    listed first and the loop construct would not test it, so there was no
    bug. However, this is fragile. Replace the terminator with -1 instead,
    and make the variable name for mode 1 syscall lists more descriptive.
