Commit c3fc47ea8e fixed EAP passthrough
server to allow Logoff/Re-authentication to be used. However, it
broke EAP standalone server while doing that. Fix this by reverting
the earlier fix and by clearing the EAP Identity information in the
EAP server code whenever an EAPOL-Start or EAPOL-Logoff packet is
received.
These are not used by any driver wrapper, i.e., only the four
data queues (BK, BE, VI, VO) are configurable. Better remove these
so that there is no confusion about being able to configure
something additional.
This is needed to avoid problems with other applications setting and
leaving the interface to IF_OPER_DORMANT state. In AP mode, the interface
is ready immediately after the keys are set, so we better make sure the
DORMANT state does not prevent normal operations after that.
Some driver wrappers may end up indicating a disassociation or
deauthentication event without the address of the station, e.g.,
based on a previous non-AP mode event. Avoid crashing hostapd
by verifying that the require address parameter is available in
the event before processing it.
This test command is supposed to change the WPS version number in all
places immediately, so make sure that the IEs used in management
frames get updated immediately.
The P2P group component is now tracking of associated stations
in the group and the Group Limit bit in the Group Capabilities
is updated based on whether there is room for new clients in
the group.
The AP operation with wpa_supplicant requires an additional callback
to get the needed event information from hostapd side so that
wpa_msg() can be called for wpa_s->parent if needed.
When a single hostapd process is controlling multiple interfaces,
apply the received or auto-generated configuration changes to all
interfaces that have enabled WPS.
When the same hostapd process is controlling multiple interfaces,
apply WPS commands (push button, add PIN, change AP PIN) to all
interfaces that are configured to use WPS.
Commit 3379a3a795 added a direct
iface->for_each_interface use without verification whether the
function is available. This works with hostapd, but not
wpa_supplicant (which crashes on segfault).
The previous implementation ended up incorrectly assuming that all
40 MHz use cases have secondary channel above the primary one. Fix this
by properly masking the secondary channel offset field and checking its
value.
This is needed to update the pointers maintained within WPS code
to use the new configuration data instead of maintaining pointers
to the old configuration which will be freed. This fixes strings in
UPnP discovery after reconfig (they used to be random freed memory..).
This seems to be the easiest way of making sure the Config Methods
value is compliant with the WSC 2.0 specification without having
to modify the configuration file. However, this will only add the
virtual flag, so the configuration files should really be updated
to specify values that match the AP design.
WPS 2.0 mandates the AP to include WPS IE in (Re)Association Response
if the matching (Re)Association Request included WPS IE. Provide the
needed WPS IE information to the driver_ops API for drivers that
process association frames internally.
Note: This modifies the driver_ops API by adding a new argument to
set_ap_wps_ie().
The Beacon frame must include UUID-E and RF Bands attributes when
in active PBC mode to allow stations to figure out that two BSSes in
PBC mode is not a PBC session overlap.
When generating the UUID based on MAC address, share the same UUID
with all interfaces. This fixes a potential issue with concurrent
dualband APs where the UUID needs to be same for PBC to work properly.
This can happen, e.g., when a P2P client connects to a P2P group
using the infrastructure WLAN interface instead of P2P group
interface. In that case, the P2P client may behave as if the GO
would be a P2P Manager WLAN AP.
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.
If CONFIG_WPS_STRICT is set, validate WPS IE(s) in management frames and
reject the frames if any of the mandatory attributes is missing or if an
included attribute uses an invalid value. In addition, verify that all
mandatory attributes are included and have valid values in the WSC
messages.
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.
While this is not strictly speaking required based on dynamic
configuration (i.e., dot11ShortPreambleOptionImplemented is static
value based on implementation, not runtime configuration), it is better
to follow local configuration parameter for short preamble in addition
to the associated station capabilities.
This function is not really needed in case of drivers that build the
HT IEs internally. However, since this can get called if ieee80211n=1
is set in hostapd.conf, we better not segfault even if the driver
does not provide hw info (hapd->iface->current_mode == NULL).
Commit 5a1cc30f1a added code that was
assuming CONFIG_WPS_UPNP is enabled whenever CONFIG_WPS is. Fix this
by making the UPnP calls conditional on CONFIG_WPS_UPNP define.
hostapd simply used its own STBC configuration in the STA's HT caps. This
resulted in TX STBC being used for STAs not supporting RX STBC, which in
turn resulted in the STA not receiving anything.
Fix this by handling the STBC flags in the same way mac80211 does. Mask
out RX STBC if we don't support TX STBC and vice versa.
Tested only with the nl80211 driver and a STBC incapable STA.
