This change breaks interoperability with older wpa_supplicant versions
(everything up to and including wpa_supplicant 0.5.10 and 0.6.5) which
incorrectly used this field as number of bytes, not bits, in RES.
Instead of falling back to full TLS handshake on expired PAC, allow the
PAC to be used to allow a PAC update with some level of server
authentication (i.e., do not fall back to full TLS handshake since we
cannot be sure that the peer would be able to validate server certificate
now). However, reject the authentication since the PAC was not valid
anymore. Peer can connect again with the newly provisioned PAC after this.
Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).
With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.
A driver was found to remove SSID IE from NDIS_WLAN_BSSID_EX IEs, but the
correct SSID is included in NDIS_802_11_SSID structure inside the BSSID
data. If this is seen in scan results, create a matching SSID IE and add it
to the end of IEs to fix scan result parsing.
Need to make sure that portValid is TRUE in order to avoid PAE state
machine going into DISCONNECTED state on eapol_sm_step(). This could be
triggered at least with OKC.
We need to cancel the group key update for a STA if a reauthentication
request is received while the STA is in pending group key update. When
canceling the update, we will also need to make sure that the PTK Group Key
state machine ends up in the correct state (IDLE) to allow future updates
in case of WPA2.
Changed EAP-FAST configuration to use separate fields for A-ID and
A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
16-octet len binary value for better interoperability with some peer
implementations; eap_fast_a_id is now configured as a hex string.
Previous version could have allowed a broken client to complete WPA (or
WPA2) authentication even if the selected proto was not enabled in hostapd
configuration.
eap_fast_prov config parameter can now be used to enable/disable different
EAP-FAST provisioning modes:
0 = provisioning disabled
1 = only anonymous provisioning allowed
2 = only authenticated provisioning allowed
3 = both provisioning modes allowed
draft-cam-winget-eap-fast-provisioning-06.txt or RFC 4851 do not seem to
mandate any particular order for TLVs, but some interop issues were noticed
with an EAP-FAST peer implementation when Result TLV followed PAC TLV. The
example in draft-cam-winget-eap-fast-provisioning-06.txt shows the TLVs in
the other order, so change the order here, too, to make it less likely to
hit this type of interop issues.
This adds all the attributes that are marked as mandatory for SoH in
IF-TNCCS-SOH v1.0. MS-Machine-Inventory does not contain correct data
(i.e., all version fields are just marked as inapplicable) and
MS-MachineName is hardcoded to wpa_supplicant@w1.fi for now.
This may be needed if the AP does not disconnect in case of EAP-FAST
unauthenticated provisioning (EAP-Failure). Adding the local short timeout
will speed up the process in such a case by reducing the wait (which can
often be up to 60 seconds).
This allows identity (etc.) variables to be removed from configuration
which is different from setting them to an empty string. For example,
EAP-SIM and EAP-AKA can now be configured to use identity string generation
from SIM/USIM by clearing the identity string in wpa_gui.
Setting the value of the SET_NETWORK command to NULL (without quotation)
unsets the variable, i.e., removes it from configuration file. This is
needed to allow GUI programs to clear variables, e.g., identity for
EAP-AKA/SIM.
