79da74a20c WPS: Generate UUID based on MAC address, if not set
Generate a SHA1 hash -based UUID from the local MAC address if the UUID
was not configured. This makes it easier to prepare for WPS since there
is no need to generate an UUID.

local copy of wireless.h and nl80211.h.

d5263983ac MFP: Remove mac80211 workaround of IGTK in monitor netdev
mac80211 can now figure out which key to use for injected frames (in
most cases), so we can remove the workaround for configuring IGTK on the
monitor interface that is used for injecting frames.

means for manual request to send a SA Query request.

805e6dc663 Disconnect the STA if EAP timeout is reached
There is not really much else the Authenticator can do if it does not
receive valid EAP response from the Supplicant/EAP peer. EAP-Failure
would need to be sent before trying to start again with
EAP-Request/Identity, but that is not allowed before the EAP peer
actually replies. Anyway, forcing a new association is likely to clean
up peer state, too, so it can help fixing some issues that could have
caused the peer not to be able to reply in the first place.

8e09c6d253 Fixed retransmission of EAP requests if no response is received
It looks like this never survived the move from IEEE 802.1X-2001 to
IEEE 802.1X-2004 and EAP state machine (RFC 4137). The retransmission
scheduling and control is now in EAP authenticator and the
calculateTimeout() producedure is used to determine timeout for
retransmission (either dynamic backoff or value from EAP method hint).

The recommended calculations based on SRTT and RTTVAR (RFC 2988) are not
yet implemented since there is no round-trip time measurement available
yet.

This should make EAP authentication much more robust in environments
where initial packets are lost for any reason. If the EAP method does
not provide a hint on timeout, default schedule of 3, 6, 12, 20, 20, 20,
... seconds will be used.

65d50f0ac6 Add RADIUS server support for identity selection hint (RFC 4284)
Previously, only the delivery option 1 from RFC 4284
(EAP-Request/Identity from the AP) was supported. Now option 3
(subsequent EAP-Request/Identity from RADIUS server) can also be used
when hostapd is used as a RADIUS server. The eap_user file will need to
have a Phase 1 user entry pointing to Identity method in order for this
to happen (e.g., "* Identity" in the end of the file). The identity hint
is configured in the same was as for AP/Authenticator case (eap_message
in hostapd.conf).

bae61562a4 Cleaned up EAPOL-Key timeout processing
dot11RSNAConfigGroupUpdateTimeOut and
dot11RSNAConfigPairwiseUpdateTimeOut MIB variables were only used in
draft versions of IEEE 802.11i, so rename these in order not to use
confusing name here.

Replaced EAPOL-Key timeout to use following timeouts (in
milliseconds): 100,1000,1000,1000 (this was 1000,1000,1000,0). There
is no point in sending out the final EAPOL-Key frame which would be
immediately followed by disconnection. After the change to allow
response to any pending EAPOL-Key frame, it is fine to send the first
retransmission quickly to avoid long wait in cases where Supplicant
did not receive the first frame for any reason. The new sequence will
still provide 3.1 seconds of time to get any response frame, so this
does not reduce the previous time.

47f72245e2 Do not allow HT with WPA/WPA2 to be enabled without CCMP
IEEE 802.11n does not allow HT STAs to use TKIP between themselves, so
do do allow a configuration that would force this to happen if HT is
used.

22a299ee9d Improve EAPOL-Key handshake stability with retransmitted frames
Accept response to any pending request, not just the last one. This
gives the Supplicant more time to reply since hostapd will now allow up
to three seconds for the reply to the first EAPOL-Key frame transmission
(and two seconds for the first retry and one second for the last) while
the previous version invalidated any old request immediately when
sending a retransmitted frame.

If the Supplicant replies to more than one request, only the first reply
to arrive at the Authenticator will be processed. As far as the
Supplicant is concerned, this behavior does not differ from the previous
one except for being less likely to cause unneeded retransmissions of
EAPOL-Key frames.

This can help in cases where power saving is used when the group key is
rekeyed or when there is excessive traffic on the channel that can delay
(or drop) EAPOL-Key frames.

to allow building against the latest libnl code.

bb9f45e0bb nl80211: Remove the debug print from data frame processing
This is currently happening way too frequently (mac80211 monitor
interface sends TX info for every frame) and the end result makes it
difficult to read hostapd debug log if there is large amount of data
traffic.

4a7b9f885f Fixed WEP authentication (both Open System and Shared Key) with mac80211
Only one of the authentication frame types is encrypted. In order for
static WEP encryption to work properly (i.e., to not encrypt the frame),
we need to tell mac80211 about the frames that must not be encrypted.

If the phy info from nl80211 does not include 802.11b mode, generate
that mode based on 802.11g information. This allows hw_mode=b to be used
with drivers that support 2.4 GHz band.

8c37556cd1 Add a starting point for EAP-AKA' (draft-arkko-eap-aka-kdf-10)
This is just making an as-is copy of EAP-AKA server and peer
implementation into a new file and by using the different EAP method
type that is allocated for EAP-AKA' (50). None of the other differences
between EAP-AKA and EAP-AKA' are not yet included.

It is likely that once EAP-AKA' implementation is done and is found to
work correctly, large part of the EAP-AKA and EAP-AKA' code will be
shared. However, it is not reasonable to destabilize EAP-AKA
implementation at this point before it is clearer what the final
differences will be.

08bec36178 WPS: Added support for wildcard PINs that work with any UUID-E
Since the Registrar may not yet know the UUID-E when a new PIN is
entered, use of a wildcard PIN that works with any UUID-E can be useful.
Such a PIN will be bound to the first Enrollee trying to use it and it
will be invalidated after the first use.

a8d05fca5f Clear various flags on re-association to allow key_mgmt changes
If a STA reassociates and changes key_mgmt (e.g., from WPA-PSK to WPS),
hostapd needs to reset some of the existing STA and WPA state machine
variables to allow correct processing for the new association.
