case CHANWIDTH_80MHZ:
data->bandwidth = 80;
if ((oper_chwidth == CHANWIDTH_80MHZ &&
center_segment1) ||
(oper_chwidth == CHANWIDTH_80P80MHZ &&
!center_segment1) ||
!sec_channel_offset)
return -1;
I'm tripping over the !sec_channel_offset check. The sec_channel_offset is only used in 40Mhz +/- (mostly sure) but is being checked when configuring 80Mhz .
The case CHANWIDTH_160MHZ also explicity checks if sec_channel_offset is nonzero but it isn't used in the subsequent calculations.
The comments in struct hostapd_freq_params seem to indicate it's only for HT40+/-.
/**
* sec_channel_offset - Secondary channel offset for HT40
*
* 0 = HT40 disabled,
* -1 = HT40 enabled, secondary channel below primary,
* 1 = HT40 enabled, secondary channel above primary
*/
int sec_channel_offset;
driver_nl80211.c uses sec_channel_offset from hostapd_freq_params but also only in setting HT 40+/-
