Fix wpa_supplicant AP build after hostapd header file cleanup 2009-03-25 15:35:26 +01:00			`struct ieee80211_mgmt;`
Move STA entry structure into sta_info.h and remove ap.h This cleans up some of the hostapd include file usage and only includes the needed STA flags into driver wrappers. 2009-03-25 15:13:35 +01:00
Mark management frame processing functions to use const buffer 2009-12-13 22:25:30 +01:00			`void handle_probe_req(struct hostapd_data *hapd,`
Pass signal strength through, fix units The signal strength is currently never used as the only driver reporting it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never populated by the kernel. The kernel will (soon) populate IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that. Also, since it was never really populated, we can redefine the signal field to be in dBm units only. My next patch will also require knowing the signal strength of probe requests throughout the code (where available), so add it to the necessary APIs.

Verify that beacon setup succeeds before proceeding There is no point in starting the AP operations unless the driver can be successfully configured to beacon. Signed-hostap: Jouni Malinen <j@w1.fi> 2013-12-24 21:46:20 +01:00			`int ieee802_11_set_beacon(struct hostapd_data *hapd);`

Add station tracking based on other management frame subtypes This extends the previous tracking design to add a station entry based on other management frames than Probe Request frames. For example, this covers a case where the station is using passive scanning.

hostapd: Add mechanism to track unconnected stations hostapd can now be configured to track unconnected stations based on Probe Request frames seen from them. This can be used, e.g., to detect dualband capable station before they have associated. Such information could then be used to provide guidance on which colocated BSS to use in case of a dualband AP that operates concurrently on multiple bands under the control of a single hostapd process.

Add option to reject authentication on 2.4 GHz from dualband STA The new no_auth_if_seen_on=<ifname> parameter can now be used to configure hostapd to reject authentication from a station that was seen on another radio. This can be used with enabled track_sta_max_num configuration on another interface controlled by the same hostapd process to reject authentication attempts from a station that has been detected to be capable of operating on another band, e.g., to try to reduce likelihood of the station selecting a 2.4 GHz BSS when the AP operates both a 2.4 GHz and 5 GHz BSS concurrently. Note: Enabling this can cause connectivity issues and increase latency for connecting with the AP. Signed-off-by: Jouni Malinen <j@w1.fi> 2015-09-05 18:00:03 +02:00			`struct hostapd_data *`
