From 909bd5926d474e275599094acad986af79671ac9 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 9 Aug 2013 12:52:31 +0300 Subject: [PATCH] Hostap: copying wrong data prism2_ioctl_giwaplist() We want the data stored in "addr" and "qual", but the extra ampersands mean we are copying stack data instead.
