On RHEL 4 U5 x86_64, if you have the following rule:
-a entry,always -S removexattr
you'd expect the result to be that the removexattr call is audited. This
isn't quite the case. What this actually means is 'audit system call
197'. The effect of this is to audit 64 bit removexattr calls and 32 bit
fstat64 calls.
I can see why this is the case, however this is clearly both undesirable
and far from intuitive. I'm not entirely sure what the solution should
be, but a big warning in the man page might be a good start :) As a
general rule, this highlights that it's always essential to additionally
filter by architecture on x86_64.
