From d419b9f0fa69e79ccba3e5e79a58a52ae0c2ed6a Mon Sep 17 00:00:00 2001 From: Reinette Chatre Date: Mon, 19 Oct 2009 14:55:37 -0700 Subject: [PATCH] mac80211: fix ibss joining Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined. Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check. Signed-off-by: Reinette Chatre Signed-off-by: John W.
