8b24861154 Add Acct-Session-Id into Access-Request messages
This optional attribute may make it easier to bind together the
Access-Request and Accounting-Request messages. The accounting session
identifier is now generated when the STA associates instead of waiting
for the actual session to start after successfull authentication.

5ee56c4e19 Keep and use list of PSKs per station for RADIUS-based PSK
This adds support for multiple PSKs per station when using a RADIUS
authentication server to fetch the PSKs during MAC address
authentication step. This can be useful if multiple users share a
device but each user has his or her own private passphrase.

ceb997f394 Fix ap_sta_disconnect() to clear EAPOL/WPA authenticator state
Number of places in hostapd use ap_sta_disconnect() instead of
ap_sta_disassociate() or ap_sta_deauthenticate(). There are some
differences between these functions, e.g., in the area how quickly
the EAPOL state machines get deinitialized. This can result in
somewhat unexpected events since the EAPOL/WPA authenticator
state machines could remain running after deauthentication.

Address this by forcing EAPOL/WPA authenticator state machines
to disabled state whenever ap_sta_disconnect() is called instead
of waiting for the deauthentication callback or other timeout
to clear the STA.

d567479153 Do not disconnect STA based on inactivity on driver failure
Now that we can use driver_nl80211.c with non-mac80211 drivers that
implement SME/MLME internally, we may not get inactivity time from the
driver. If that is the case, we need to skip disconnection based on
maximum inactivity timeout. This fixes some unexpected disconnection
cases with ath6kl in AP mode.

ef01fa7bfa hostapd: Make inactivity polling configurable
hostapd uses the poll method to check if the station is alive
after the station has been inactive for ap_max_inactivity seconds.
Make the poll mechanism configurable so that user can choose to
disconnect idle clients.

This can be especially useful when some devices/firmwares have
restrictions on the number of clients that can connect to the AP
and that limit is smaller than the total number of stations trying
to use the AP.

05ab9712b9 Allow WPA passphrase to be fetched with RADIUS Tunnel-Password attribute
This allows per-device PSK to be configured for WPA-Personal using a
RADIUS authentication server. This uses RADIUS-based MAC address ACL
(macaddr_acl=2), i.e., Access-Request uses the MAC address of the
station as the User-Name and User-Password. The WPA passphrase is
returned in Tunnel-Password attribute in Access-Accept. This
functionality can be enabled with the new hostapd.conf parameter,
wpa_psk_radius.

1473f95e98 AP: Use QoS nullfunc for connection poll
When polling a station that has been inactive for a while, hostapd currently
always uses a null data frame. This is a bit strange with uAPSD clients
(though it seems to mostly work) since the EOSP bit can never be set in a
non-QoS frame. Make hostapd use QoS null data frames for probing when the
station is a QoS STA.

cc28ad8cdf Fix Deauth/Disassoc callback handling with test frames
The Deauth/Disassoc TX status callbacks were ending up kicking the
station entry from kernel driver when test functionality was used to
inject Deauth/Disassoc frames from the AP with the purpose of leaving
the local association in place. Fix this by using STA flags to figure
out whether there was a pending callback for the frame that we need
to act on.

In addition, add forgotten functionality for the Disassoc TX status
callback to match the behavior with Deauth.

4dc03726de Delay STA entry removal until Deauth/Disassoc TX status in AP mode
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.

This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.

cee7d66b1d hostapd: Start removing struct hostapd_driver_ops abstraction
Commit bf65bc638f started the path to
add this new abstraction for driver operations in AP mode to allow
wpa_supplicant to control AP mode operations. At that point, the
extra abstraction was needed, but it is not needed anymore since
hostapd and wpa_supplicant share the same struct wpa_driver_ops.

Start removing the unneeded abstraction by converting
send_mgmt_frame() to an inline function, hostapd_drv_send_mlme().
This is similar to the design that is used in wpa_supplicant and
that was used in hostapd in the past (hostapd_send_mgmt_frame()
inline function).
