The previous implementation did not check that we are associated with the sender of the GAS response before checking for PMF status. This could have accepted Venue URL when not in associated state. Fix this by explicitly checking for association with the responder first. This fixes an issue that was detected, e.g., with these hwsim test case sequences: gas_anqp_venue_url_pmf gas_anqp_venue_url gas_prot_vs_not_prot gas_anqp_venue_url Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
