Subject: [PATCH v3 0/2] landlock: clarify TTY signal scoping
Date: Wed, 23 Sep 2026 12:33:19 -0400 [thread overview]
Message-ID: <20260923163321.79770-1-clusk@northecho.dev> (raw)
Document that a PTY master retains control over processes attached to the
terminal, and add a selftest covering this boundary alongside the direct
signal restriction.
Since v2, the documentation follows Mickaël's capability framing, the UAPI
description refers to arbitrary signal targets, and the series includes the
requested selftest.
