Without md5sig we can't exhaust the TCP option space. This series explcitly disable MPTCP when md5sig is set, and cleanup later option len checks with the assumption that TCP option space exhaustion is not expected - add a single WARN_ON() for that. Paolo Abeni (1): mptcp: move mp_capable initialization at subflow_init_req() start mptcp: disable on req sk if MD5SIG is enabled mptcp: warn once if exceeding tcp opt space for dss/mp_capable mptcp: remove unneeded check in mptcp_established_options_mp() net/mptcp/subflow.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- = 2.21.0 --===============6562019806292333207==--
