Subject: P2PS: Save wps_prov_info on the responder side
X-Git-Tag: hostap_2_5~449
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=223ccebfa3e6ef249a9715209521c34f946c35d4;p=thirdparty%2Fhostap.git

P2PS: Save wps_prov_info on the responder side

When device A sends PD response to device B, device A should save
wps_prov_info for device B. Not doing so would result in a redundant and
incorrect PD flow, e.g., when upon PROV-DISC-DONE event device B starts
a GO and device A should join it.
