From 8dadadb7e977a91b46ed3549f9d2f22a629e5043 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 4 Aug 2009 09:32:23 +0200 Subject: [PATCH] cfg80211: clear SSID on disconnect/no connection The SME state machine in cfg80211 uses the SSID stored in struct wireless_dev internally, but fails to clear it in multiple places (when giving up on a connection attempt and when disconnecting). This doesn't matter to the SME state machine, but does matter for IBSS. Thus, in those cases, clear the SSID to avoid messing up the IBSS state machine.
