[Ltrace-devel] deny_ptrace SELinux option

[Petr Machata]

Hi there,

I added a new configury flag, HAVE_LIBSELINUX.  I also added a new back
end hook, trace_fail_warning(pid_t), which is called when we fail to
PTRACE_ATTACH or PTRACE_TRACEME.  If we HAVE_LIBSELINUX, this hook
checks value of deny_ptrace SELinux boolean and if it finds it turned
on, it warns the user that they should turn it off.  The code for this
was lifted more or less verbatim from GDB.

Thanks,
PM
