From 6f72577f2963759898f18e86294c275aaed9de9a Mon Sep 17 00:00:00 2001 From: Ilan Peer Date: Mon, 2 Sep 2013 15:40:59 +0300 Subject: [PATCH] P2P: Handle INTERFACE_DISABLED event on a P2P GO interface An INTERFACE_DISABLED event received on an interface that is currently operating a P2P GO means that the group session ended. In such a case, if the interface was dynamically added remove it, and if not, remove all the network blocks that are temporary, assuming that if needed a new session will be started by an external entity. The use case was triggering rfkill (both SW and HW). This case popped up as part of a testing cycle, where after a toggle in the rfkill state, the result was that the interface was not deleted, but on the other hand the wpa_supplicant did not configure the kernel to re-start the AP functionality again.
