2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Benoit Papillault <benoit.papillault(a)free.fr>

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.
