This fixes association with such networks when the AP puts 0 into the field, previously we'd disconnect due to an invalid channel with the message wlan0: AP VHT information is invalid, disable VHT Cc: stable@vger.kernel.org Fixes: f2d9d270c15ae ("mac80211: support VHT association") Reported-by: Tim Nelson Signed-off-by: Johannes Berg --- diff --git a/net/mac80211/mlme.c b/net/mac80211/mlme.c index c415f00cd6b6..245dce969b31 100644 --- a/net/mac80211/mlme.c +++ b/net/mac80211/mlme.c @@ -222,6 +222,7 @@ ieee80211_determine_chantype(struct ieee80211_sub_if_data *sdata, switch (vht_oper->chan_width) { case IEEE80211_VHT_CHANWIDTH_USE_HT: vht_chandef.width = chandef->width; + vht_chandef.center_freq1 = chandef->center_freq1; break; case IEEE80211_VHT_CHANWIDTH_80MHZ: vht_chandef.width = NL80211_CHAN_WIDTH_80;
