Hello Vladimir Kondratiev,
The patch 3a0c52a6d82c: "cfg80211: add 802.11ad (60gHz band) support"
from Jul 2, 2012, leads to the following warning:
drivers/net/wireless/mac80211_hwsim.c:1841 init_mac80211_hwsim()
warn: buffer overflow 'data->bands' 2 <= 2
drivers/net/wireless/mac80211_hwsim.c
1839
1840 for (band = IEEE80211_BAND_2GHZ; band < IEEE80211_NUM_BANDS; band++) {
^^^^^^^^^^^^^^^^^^^
We raised IEEE80211_NUM_BANDS to 3.
1841 struct ieee80211_supported_band *sband = &data->bands[band];
^^^^^^^^^^^
This only has 2 elements still.
1842 switch (band) {
1843 case IEEE80211_BAND_2GHZ:
It causes a bogus dereference later.
regards,
dan carpenter
