It is used if +driver doesn't report NL80211_ATTR_DEVICE_AP_SME and doesn't support +monitor interface. In such situation: +1) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails +2) We don't try subscribing for WLAN_FC_STYPE_ACTION +3) We fallback to AP SME mode after failing to create monitor interface +4) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails +Above scenario is used, e.g., with brcmfmac. As you can see - thanks to +events provided by cfg80211 - it's not really required to receive Probe +Request or action frames. + +However, the previous implementation did not allow using hostapd with +drivers that: +1) Report NL80211_ATTR_DEVICE_AP_SME +2) Don't support subscribing for PROBE_REQ and/or ACTION frames +In case of using such a driver hostapd will cancel setup after failing +to subscribe for WLAN_FC_STYPE_ACTION. I noticed it after setting flag +WIPHY_FLAG_HAVE_AP_SME in brcmfmac driver for my experiments. + +This patch allows working with such drivers with just a small warning +printed as debug message. + +Signed-off-by: Rafał Miłecki <zajec5@gmail.com> +--- + src/drivers/driver_nl80211.c | 3 ++- + 1 file changed, 2 insertions(+), 1 deletion(-) + +--- a/src/drivers/driver_nl80211.c ++++ b/src/drivers/driver_nl80211.c +@@ -4108,7 +4108,8 @@ static int nl80211_setup_ap(struct i802_ + + if (drv->device_ap_sme && !drv->use_monitor) + if (nl80211_mgmt_subscribe_ap_dev_sme(bss)) +- return -1; ++ wpa_printf(MSG_DEBUG, ++ "nl80211: Failed to subscribe for mgmt frames from SME driver - trying to run without it"); + + if (!drv->device_ap_sme && drv->use_monitor && + nl80211_create_monitor_interface(drv) && |
