Pathnames are only used for informational purposes in the kernel, except in AppArmor of course. /proc only uses pathnames in a few places, but /proc/mounts will silently fail and produce garbage entries. That's not ideal of course; we should fix that somehow. Note that this has nothing to do with the AppArmor discussion ... > Perhaps vfs should be modified not to allow such crazy paths? But placing > limit in aa is ugly. Dream on. Redefining fundamental vfs semantics is not an option; we should rather make sure that we fail gracefully. Considering the alternatives, I still prefer the configurable limit. That's way more useful than allowing a process to DOS the kernel with AppArmor.
