9776475fb9 WPS: Do not proxy Probe Request frames to foreign SSIDs to Registrars
We must only indicate stations that are either probing the wildcard SSID
or our own SSID.

84b2f9909f Fix driver operation order in configuration reloading
Some of the driver wrappers need to get set_ieee8021x() call before
they can configure keys. Reorder the operations in the reloading
of configuration case to match with that expectation.

ed7a09f914 Add WPS IE into (Re)Association Response frame if WPS is used
If the associating station indicates that it is intents to use WPS
by including WPS IE in (Re)Association Request frame, include WPS IE
in (Re)Association Response frame.

fragmentation of WPS TLVs in (Re)Association Request frames.

6deb41e73f Update WPS IE on hostapd reconfiguration
This is needed to handle cases where WPS state may have changed and
hostapd is reloading its configuration.

1bc774a12a hostapd: Reorder some IEs to get closer to IEEE 802.11 standard
Vendor-specific IEs are supposed to be in the end of the frame, so move
WMM into the end of Beacon, Probe Response, and (Re)Association Response
frames. In addition, move HT IEs to be later in (Re)Association
Response to match the correct order.

hostapd_eid_wpa() adds multiple IEs and the end result may not always be
correct. If WPA is enabled, WPA IE (vendor-specific) gets added in the
middle of the frame and not in the end. This would require a larger
change to spliut the IEs from WPA module into separate locations when
constructing Beacon and Probe Response frames. This is not yet addressed.

439d4bf960 Fix EAPOL_SM_USES_WPA flag to be set correctly
Commit c02d52b405 removed direct calls
to the WPA authenticator, but the change here was incorrect.
EAPOL_SM_USES_WPA was supposed to be set based on sta->wpa_sm being
set, i.e., no need to check for PMKSA entries for that.

While this could potentially change EAPOL Key TX state machine behavior,
no clear problems have been identified so far. Anyway, better fix this
to get the correct flags set for EAPOL authenticator state machine.

3ab72b626b Fix WPA state machine initialization on WPA_REAUTH if needed
When using WPS, we may end up here if the STA manages to re-associate
without the previous STA entry getting removed. Consequently, we need to
make sure that the WPA state machines gets initialized properly at this
point.

e34ce1683c VLAN: Reorder init to get same behavior for all VLAN interfaces
Both the wildcard VLAN entry and the statically configured VLAN
interfaces should behave in the same way. Initializing the
full dynamic VLAN code before adding the statically configured VLAN
interfaces allows the same processing to be applied to both statically
and dynamically added VLAN interface (i.e., also the statically
configured ones will be added to a bridge).

c47cf42e4b WPS: Fix association when both WPS and WPA/RSN IE are included
The WPS IE was overriding the WPA/RSN IE in driver based MLME case
(hostapd_notif_assoc), but the MLME code here was not using WPS IE
correctly, i.e., it allowed the WPA/RSN IE override the operation.

f3585c8a85 Simplify driver_ops for virtual interface add/remove
There is no absolute requirement for separating address allocation
into separate functions, so simplify the driver wrapper interface
to use just if_add and if_remove instead of adding the new
alloc_interface_addr() and release_interface_addr() functions.

if_add() can now indicate if the driver forced a different interface
name or address on the virtual interface.

functionality is implemented outside hostapd, add support to advertise
the functionality in beacon.

26e23750b9 FT: Fix FT 4-Way Handshake to include PMKR1Name in messages 2 and 3
IEEE Std 802.11r-2008, 11A.4.2 describes FT initial mobility domain
association in an RSN to include PMKR1Name in the PMKID-List field
in RSN IE in messages 2/4 and 3/4. This makes the RSN IE not be
bitwise identical with the values used in Beacon, Probe Response,
(Re)association Request frames.

The previous versions of wpa_supplicant and hostapd did not add the
PMKR1Name value in EAPOL-Key frame and did not accept it if added
(due to bitwise comparison of RSN IEs). This commit fixes the
implementation to be compliant with the standard by adding the
PMKR1Name value into EAPOL-Key messages during FT 4-Way Handshake and
by verifying that the received value matches with the value derived
locally.

This breaks interoperability with previous wpa_supplicant/hostapd
versions.

68532a9ceb Avoid hostapd segfault on invalid driver association event

99f4ae67b7 Fix WPA/RSN IE update on reconfig with set_generic_elem()
IF WPA/RSN parameters were changed or WPA/RSN was disabled, the
WPA/RSN IE in Beacon/Probe Response frames was only update with
set_beacon(). We need to do this with set_generic_elem(), too, to
work with all driver wrappers.

set_beacon() instead of set_ap_wps_ie() (i.e., nl80211).

81a658d754 FT: Re-set PTK on reassociation
It turns out that this is needed for both FT-over-DS and FT-over-air
when using mac80211, so it looks easiest to just unconditionally
re-configure the keys after reassociation when FT is used.
