This patch drops id 0 limitation in mptcp_nl_cmd_sf_create() to allow creating additional subflows with the local addr ID 0. There is no reason not to allow additional subflows from this local address: we should be able to create new subflows from the initial endpoint. This limitation was breaking fullmesh support from userspace. Fixes: 702c2f64 ("mptcp: netlink: allow userspace-driven subflow establishment") Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/391 Cc: stable@vger.kernel.org Suggested-by: Matthieu Baerts <matthieu.baerts@tessares.net> Reviewed-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Mat Martineau <martineau@kernel.org> Link: https://lore.kernel.org/r/20231004-send-net-20231004-v1-2-28de4ac663ae@kernel.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>
