[PATCH v4 0/3] Refactor Landlock access mask management

Posted by Mickaël Salaün 2 weeks ago

Hi,

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

This fourth version mainly rename these helpers.

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