Move internal EAPOL authenticator defines into their own file This is an initial step in further cleaning up the EAPOL authenticator use to avoid requiring direct accesses to the internal data structures. For now, number of external files are still including the internal definitions from eapol_auth_sm_i.h, but eventually, these direct references should be removed.

Fix Suite B 192-bit AKM to use proper PMK length In addition to the PTK length increasing, the length of the PMK was increased (from 256 to 384 bits) for the 00-0f-ac:12 AKM. This part was missing from the initial implementation and a fixed length (256-bit) PMK was used for all AKMs. Fix this by adding more complete support for variable length PMK and use 384 bits from MSK instead of 256 bits when using this AKM. This is not backwards compatible with the earlier implementations. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>

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. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

Add Acct-Multi-Session-Id into RADIUS Accounting messages This allows multiple sessions using the same PMKSA cache entry to be combined more easily at the server side.

RADIUS: Use more likely unique accounting Acct-{,Multi-}Session-Id Rework the Acct-Session-Id and Acct-Multi-Session-Id implementation to give better global and temporal uniqueness. Previously, only 32-bits of the Acct-Session-Id would contain random data, the other 32-bits would be incremented. Previously, the Acct-Multi-Session-Id would not use random data. Switch from two u32 variables to a single u64 for the Acct-Session-Id and Acct-Multi-Session-Id. Do not increment, this serves no legitimate purpose. Exclusively use os_get_random() to get quality random numbers, do not use or mix in the time. Inherently take a dependency on /dev/urandom working properly therefore. Remove the global Acct-Session-Id and Acct-Multi-Session-Id values that serve no legitimate purpose. Signed-off-by: Nick Lowe <nick.lowe@lugatech.com>
