Subject: [PATCH bpf-next] mptcp: Add struct mptcp_sock definition when CONFIG_MPTCP is disabled
Date: Mon, 11 Jul 2022 15:07:31 +0200 [thread overview]
Message-ID: <20220711130731.3231188-1-jolsa@kernel.org> (raw)
The btf_sock_ids array needs struct mptcp_sock BTF ID for
the bpf_skc_to_mptcp_sock helper.
When CONFIG_MPTCP is disabled, the 'struct mptcp_sock' is not
defined and resolve_btfids will complain with:
BTFIDS vmlinux
WARN: resolve_btfids: unresolved symbol mptcp_sock
Adding empty difinition for struct mptcp_sock when CONFIG_MPTCP
is disabled.
