Subject: [PATCH] cfg80211: fix truncated IEs
Date: Thu, 30 Apr 2009 20:09:56 +0200 [thread overview]
Message-ID: <1241114996.29878.22.camel@johannes.local> (raw)
Another bug in the "cfg80211: do not replace BSS structs" patch,
a forgotten length update leads to bogus data being stored and
passed to userspace, often truncated.
