[PATCH] wext: Fix IWENCODEEXT security permissions
Check the permissions when user-space try to read the encryption parameters via SIOCGIWENCODEEXT. This is trivial and probably should go in 2.6.17... Bug was found by Brian Eaton <eaton.lists@gmail.com>, thanks ! Signed-off-by: Jean Tourrilhes <jt@hpl.hp.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
