Author: avos Date: Thu Jan 7 18:41:03 2016 New Revision: 293339 URL: https://svnweb.freebsd.org/changeset/base/293339 Log: net80211 drivers: fix ieee80211_init_channels() usage Fix out-of-bounds read (all) / write (11n capable) for drivers that are using ieee80211_init_channels() to initialize channel list. Tested with: * RTL8188EU, STA mode. * RTL8188CUS, STA mode. * WUSB54GC, HOSTAP mode.
