92eb00aec2 Extend ACL check for Probe Request frames
Extend ACL check to deny Probe Request frames for the client which does
not pass ACL check. Skip this check for the case where RADIUS ACL is
used to avoid excessive load on the RADIUS authentication server due to
Probe Request frames. This patch add wpa_msg event for auth and assoc
rejection due to acl reject.

1889af2e0f VLAN: Separate station grouping and uplink configuration
Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.

The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.

New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.

When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.

To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.

Though not depended on by the code, vlan_id assignment ensures:
  * vlan_id = 0 will continue to mean no AP_VLAN interface
  * vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
    with no per_sta_vif and no extra tagged vlan.
  * vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.

This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.

DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.

MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.

Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).

Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

0603bcb7fe hostapd: Process MAC ACLs on a station association event (SME in driver)
Now hostapd will use station MAC-based permissions according to the
macaddr_acl policy also for drivers which use AP SME offload, but do not
support NL80211_CMD_SET_MAC_ACL for offloading MAC ACL processing. It
should be noted that in this type of case the association goes through
and the station gets disconnected immediately after that.

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.

1057d78eb8 Move generic AP functionality implementation into src/ap
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.
