[PATCH v3 0/3] Refactor Landlock access mask management

Posted by Mickaël Salaün 1 month ago

Hi,

To simplify code for new access types [1], add 2 new helpers:
- landlock_merge_access_masks()
- landlock_match_ruleset()

This third version mainly use a new union access_masks_all type instead
of changing struct access_masks.

The last patch uses these helpers to optimize Landlock scope management
like with filesystem and network access checks.
