[PATCH] add rule filterkey
Add support for a rule key, which can be used to tie audit records to audit rules. This is useful when a watched file is accessed through a link or symlink, as well as for general audit log analysis. Because this patch uses a string key instead of an integer key, there is a bit of extra overhead to do the kstrdup() when a rule fires. However, we're also allocating memory for the audit record buffer, so it's probably not that significant. I went ahead with a string key because it seems more user-friendly. Note that the user must ensure that filterkeys are unique. The kernel only checks for duplicate rules. Signed-off-by: Amy Griffis <amy.griffis@hpd.com>
