TOMOYO Linux needs method for calculating pathname in LSM module.
However, we have received comment from Al Viro, the vfs maintainer,
that adding vfsmount parameter to vfs helper functions (and LSM hooks)
is not preferable. We have asked some people (including Al), and we
came back to the most straightforward approach; adding new LSM hooks
where vfsmount is available.
The attached patch introduces several new LSM hooks TOMOYO Linux
needs. It has less impact to existing LSM module and no impact to vfs
helper functions. Please review it.
I don't see any technical errors in this patch.
If it is going to be merged, please make a new config option for
path-based hooks (similar to that for the network hooks), so they can be
compiled out.
one question about these new hook locations.
it is possible to gather all the info that was gathered at the old hook
locations from the new ones? I realize that you are not eliminating the
old hooks (and possibly can't for backwards compatibility), but possibly
they should be depriciated in favor of the new locations if they can
satisfy both the old uses and new use cases.
