Before we decide to use the pers flag for this, I want to understand personality more.
I added an additional
printf("Personality: %ld\n", personality(0xffffffff));
statement in the test case before you make the call
personality(0x08);
Before you explicitly set personality to 8 in the test, personality is always=0 whether you compile the test in 64bit or 32bit mode.
Is that the expected behavior? Can you not tell from personality if something was compiled in 32bit vs 64bit mode?

Actually, this should be the syscall number that auditctl was compiled with.

I don't think so. How does it know what personalities you want to watch?

How about we make pers take a list? This could be implemented one of 2 ways.
auditctl can generate a rule for each personality. Or with some changes in
the kernel, we can make personality act more like a bit mask so that we don't
have to load as many rules in the kernel.
Userspace can generate a mask or separate rules. Any preferences?
