[PATCH v2 0/3] Refactor Landlock access mask management

From: Mickaël Salaün
Date: Mon Oct 14 2024 - 08:49:36 EST


Hi,

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

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

Previous version:
v1: https://lore.kernel.org/r/20241001141234.397649-1-mic@xxxxxxxxxxx
