Subject: [PATCH net-next 3/6] selftests: drv-net: psp: check the ifindex an associated netns sees
Date: Sat, 12 Sep 2026 13:04:23 -0700 [thread overview]
Message-ID: <20260912200426.121025-4-kuba@kernel.org> (raw)
In-Reply-To: <20260912200426.121025-1-kuba@kernel.org>
dev-get must not report the ifindex outside of the main netns.
The dev-get checks for an associated namespace are already there,
add the "no main ifindex" assertion.
