From 74c3cbe33bc077ac1159cadfea608b501e100344 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 22 Jul 2007 08:04:18 -0400 Subject: [PATCH] audit: watching subtrees New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.
