Subject: [PATCH v2 2/2] selftests/bpf: Use local type for bpf_fou_encap in test_tunnel_kern
Date: Fri, 17 Apr 2026 11:41:22 -0400 [thread overview]
Message-ID: <20260417154122.2558890-3-grbell@redhat.com> (raw)
In-Reply-To: <20260417154122.2558890-1-grbell@redhat.com>
Replace the forward-declared struct bpf_fou_encap with the existing
bpf_fou_encap___local type in the bpf_skb_set_fou_encap and
bpf_skb_get_fou_encap declarations. This removes the need for
the forward declaration and the explicit casts at each call.
Fixes: d17f9b370df6 ("selftests/bpf: Fix compilation failure when CONFIG_NET_FOU!=y")
Signed-off-by: Gregory Bell <grbell@redhat.com>
