From de30e10d0080bccca8fe56f8dcb75171fffdb695 Mon Sep 17 00:00:00 2001 From: Benoit Papillault Date: Fri, 5 Feb 2010 01:21:03 +0100 Subject: mac80211: Fix probe request filtering in IBSS mode commit 0da780c269957783d341fc3559e6b4c9912af7b4 upstream. We only reply to probe request if either the requested SSID is the broadcast SSID or if the requested SSID matches our own SSID. This latter case was not properly handled since we were replying to different SSID with the same length as our own SSID. Signed-off-by: Benoit Papillault Signed-off-by: John W.
