Subject: Re: [PATCH v5 2/8] landlock: Wrap per-layer access masks in struct layer_config
Date: Wed, 07 Oct 2026 10:10:16 +0000 [thread overview]
Message-ID: <sashiko-outbox-162841@kernel.org> (raw)
In-Reply-To: <20261007100255.1333386-3-mic@digikod.net>
> The domain layer FAM stores struct access_masks values directly, while a
> ruleset stores the equivalent single mutable value. Per-category
> permissions need additional per-layer data beyond the handled-access
> bitfields.
>
> Introduce struct layer_config as the common value type. Keeping the
> handled bitfields in its .handled member leaves struct access_masks as a
> lightweight parameter type for functions that only need those bitfields,
> while the complete layer can be snapshotted with one assignment.
>
> At this point struct layer_config only wraps the four-byte access_masks,
> so it does not grow the per-domain allocation: the maximum 16-entry FAM
> remains 64 bytes.
>
> No functional change.
