a9d1364c5f Merged EAP-AKA' into eap_aka.c and added it to defconfig/ChangeLog 2008-12-07 19:24:56 +02:00

01b0569437 Added protection against EAP-AKA' -> EAP-AKA bidding down attacks
AT_BIDDING attribute is included in EAP-AKA/Challenge to allow peer to
know whether the server would have preferred EAP-AKA'.

a478ef0d12 EAP-AKA': Added CK',IK' derivation
This is based on a change request 3GPP TS 33.402 CR 0033 for version
8.1.1. The hardcoded ANID is now 'WLAN' since that is used in
3GPP TS 24.302.

a49c428a1b EAP-AKA': Comment out EAP-AKA' server KDF negotiation
Since only one KDF is currently supported, the negotiation is not
allowed and peer must be rejected if it tries to send KDF selection in a
Challenge message. The negotiation code is left in the file and just
commented out since it was tested to work and can be used in the future
if another KDF is added.

6ec4021c03 EAP-AKA': Added processing of AT_KDF and AT_KDF_INPUT attributes
Network Name is not yet generated and validated based on 3GPP.33.402
(i.e., a hardcoded string is used in server and anything is accepted in
peer).

b8ab624984 Fixed EAP-SIM and EAP-AKA AT_IDENTITY parsing (server only)
The attribute uses 'Actual Identity Length' field to indicate the exact
(pre-padding) length of the Identity. This actual length should be used
as the length, not the remaining attribute length.

This was previously worked around by stripping null termination away
from the end of the identity string at EAP-SIM and EAP-AKA server code.
However, it is likely that that workaround is not really needed and the
real problem was in AT_IDENTITY parsing. Anyway, the workaround is left
in just in case it was really needed with some implementations.

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.

15828ba820 Made 802.11 management frame IE parser aware of vendor HT Capab IE
This IE is not (at least yet) actually used for anything, but parsing it
cleans up verbose debug log a bit since thie previously unknown, but
commonly used, vendor IE was being reported as unknown.

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.

73d48dc4b4 EAP-AKA': Allow both AKA AKA' to be registed from eap_aka_prime.c
This allows the same source code file to be shared for both methods. For
now, this is only in eap_aka_prime.c, but eventually, changes in
eap_aka_prime.c are likely to be merged into eap_aka.c at which point
the separate eap_aka_prime.c can be removed.

f07688e37d nl80211: Generate 802.11b mode based on 802.11g information
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.

f09d19d46a Use a variable to store EAP method type for EAP-AKA vs. EAP-AKA'
This makes it easier to eventually replace EAP-AKA implementation with a
shared implementation that supports both EAP-AKA and EAP-AKA'.

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.

e8ff1e594e Fixed non-HT (and GF, 20 MHz) counting

the same AP without the old STA entry being removed.

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.

0a40ec6a90 Always clear EAP altAccept and altReject variables on new association
Previously, this was only done when the new connection is using
WPA-Personal. However, it looks like it was possible to trigger an
infinite busy loop if altAccept or altReject were left set to true and
an EAPOL frame is received (eapolEap is set to true). Clearing altAccept
and altReject for each association prevents this loop from happening in
the beginning of the next association.

351f09a221 WPS: Added support for fragmented WPS IE in Beacon and Probe Response
Fragment WPS IE if needed to fit into the IE length limits in hostapd
and Reassemble WPS IE data from multiple IEs in wpa_supplicant.

In addition, moved WPS code from events.c into wps_supplicant.c to clean
up module interfaces.

New control interface commands WPS_PBC, WPS_PIN, and WPS_REG can be used
to start WPS processing. These add and select the WPS network block into
the configuration temporarily, i.e., there is no need to add the WPS
network block manually anymore.

b8a8c299c8 WPS: Moved WPS IE building for ProbeReq/AssocReq into wps.c
These functions fit in better with the category of functions included in

only crypto code).

eb76b7e3ff WPS: Parse Request Type from WPS IE in (Re)AssocReq and derive mgmt keys
WPS IE is now passed from hostapd association processing into EAP-WSC
and WPS processing. Request Type attribute is parsed from this
information and if the request is for a WLAN Manager Registrar,
additional management keys are derived (to be used with UPnP).

116654ce24 WPS: Moved wps_context initialization into wps_supplicant.c
The wps_context data is now managed at wpa_supplicant, not EAP-WSC. This
makes wpa_supplicant design for WPS match with hostapd one and also
makes it easier configure whatever parameters and callbacks are needed
for WPS.

bcbbc7af45 WPS: Merged two cred_cb variables into the same one
Previously, wpa_supplicant as Enrollee case was handled using a
different callback function pointer. However, now that the wps_context

all cases.

fa201b694f WPS: Move WPS glue code from wpas_glue.c to wps_supplicant.c
This cleans up the internal interface between different modules and is

as WPS is concerned.

ff434cbdda WPS: Moved device attributes into wps_context::dev for Enrollee case
Previously, hardcoded values were used in wps_enrollee.c. These are now
moved into shared data in struct wps_context. In case of
AP/Authenticator, these are initialized in wps_hostapd.c. In case of
client/supplicant, these are now initialized in EAP-WSC peer method,
but will probably end up being moved into higher layer for better
configuration.

9d695f3dd0 WPS: Update supplicant configuration when acting as an external Registrar

3f42d42c07 WPS: Moved Credential building to use struct wps_credential
This makes it easier to store old AP settings into wps->cred (and allow
them to modified and taken into use in the future). Separation between
Credential and AP Settings building is also cleaner in this design.
