Subject: p80211wext.c: problem with IW_ENCODE_ALG_WEP
Date: Tue, 5 May 2009 15:22:43 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.64.0905051522010.9552@pc-004.diku.dk> (raw)
From: Julia Lawall <julia@diku.dk>
The expression !(ext->alg & IW_ENCODE_ALG_WEP) appears to be incorrect,
because there are several possible values for ext->alg that give 1 when
bit-anded with IW_ENCODE_ALG_WEP. Therefore Richard Kennedy suggested to
rewrite the code with !=
