Dear Monks,

I have a script that runs fine on a Windows platform. The script is distributed to a number of users in binary form by means of PAR:pp.

Now the script has been ported to Linux, where it also runs well, but with one caveat: it requires root privileges in order to perform its tasks (which involve monitoring of network interfaces).

Now users shouldn't be required to work under uid 0, so the natural solution is to make the script (or better, its pp'ed binary counterpart) suid root.

This, in turn, enables taint checks - and the script does not pass them...

I understand that the "clean" solution would be to make the script safe. However

• the script is used on systems where every user has root access
• and reviewing about 50 KLOC for securing a script on a system where everyone has root access anyway doesn't look like a rewarding activity.

So what I'm looking for is a way to disable taint checks on a pp'ed binary that's suid root.

I figure that passing "-UX" to 'perl' would do the job, but I did not find a way to pass those options to a pp'ed binary. Is there any?

Would there by any other way to disable taint checks?
