[PATCH] Filter rule comparators
Currently, audit only supports the "=" and "!=" operators in the -F filter rules. This patch reworks the support for "=" and "!=", and adds support for ">", ">=", "<", and "<=". This turned out to be a pretty clean, and simply process. I ended up using the high order bits of the "field", as suggested by Steve and Amy. This allowed for no changes whatsoever to the netlink communications. See the documentation within the patch in the include/linux/audit.h area, where there is a table that explains the reasoning of the bitmask assignments clearly. The patch adds a new function, audit_comparator(left, op, right). This function will perform the specified comparison (op, which defaults to "==" for backward compatibility) between two values (left and right). If the negate bit is on, it will negate whatever that result was. This value is returned.
