It looks like [MS-PEAP] 3.2.5.6 points towards this being the expected
behavior (however, that chapter is very confusing).
In addition, remove Cryptobinding TLV from response if the received
Cryptobinding TLV is not valid. Add some more debug messages to the case
where the received Cryptobinding TLV is found invalid.
I fixed the engine issue in phase2 of EAP-TTLS. The problem was that you
only defined one engine variable, which was read already in phase1. I
defined some new variables:
engine2
engine2_id
pin2
and added support to read those in phase2 wheres all the engine
variables without number are only read in phase1. That solved it and I
am now able to use an engine also in EAP-TTLS phase2.
Find attached the patch that creates a new driver: roboswitch. This
driver adds support for wired authentication with a Broadcom
RoboSwitch chipset. For example it is now possible to do wired
authentication with a Linksys WRT54G router running OpenWRT.
LIMITATIONS
- At the moment the driver does not support the BCM5365 series (though
adding it requires just some register tweaks).
- The driver is also limited to Linux (this is a far more technical
restriction).
- In order to compile against a 2.4 series you need to edit
include/linux/mii.h and change all references to "u16" in "__u16". I
have submitted a patch upstream that will fix this in a future version
of the 2.4 kernel. [These modifications (and more) are now included in
the kernel source and can be found in versions 2.4.37-rc2 and up.]
USAGE
- Usage is similar to the wired driver. Choose the interfacename of
the vlan that contains your desired authentication port on the router.
This name must be formatted as <interface>.<vlan>, which is the
default on all systems I know.
Remove the old code from driver_wext.c since the private ioctl interface is
never going to be used with mac80211. driver_nl80211.c has an
implementation than can be used with mac80211 (with two external patches to
enable userspace MLME configuration are still required, though).
These typedefs were causing build issues with new kernel/C library headers,
so lets get rid of them since they do not seem to be needed anymore. This
applies only if CONFIG_FULL_DYNAMIC_VLAN is enabled which is not even
mentioned in the defconfig file, so this should not change behavior more
most users.
If the driver wrapper does not implement passive_scan handler, do not try
to use strerror() to figure out what the error meant. This is not really an
error that the user should be notified about.
(e.g., via driver_nl80211 when using mac80211) instead of using hostapd as
the source of the regulatory information (i.e., information from CRDA is
now used with mac80211); this allows 5 GHz channels to be used with hostapd
(if allowed in the current regulatory domain).
Updated OpenSSL code for EAP-FAST to use an updated version of the
session ticket overriding API that was included into the upstream
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
needed with that version anymore).
It looks like ACS did not like PAC Acknowledgment TLV before Result TLV, so
reorder the TLVs to match the order shown in a
draft-cam-winget-eap-fast-provisioning-09.txt example. This allows
authenticated provisioning to be terminated with Access-Accept (if ACS has
that option enabled). Previously, provisioning was otherwise successful,
but the server rejected connection due to not understanding the PAC Ack
("Invalid TEAP Data recieved").
This is the first step in replacing SSL_set_hello_extension() with a new
SSL_set_session_ticket_ext() function that can only be used to override the
session ticket extension, not any arbitrary TLS extension.
SSL_set_hello_extension() is still present as a simple wrapper in this
version to avoid changing the API and to make testing with wpa_supplicant
and hostapd easier. It can be eventually removed when the patch is going in
into OpenSSL distribution.
GCC 4.4 cleaned up some more C++ headers. You always have to #include
headers directly and cannot rely for things to be included indirectly.

delaying Michael MIC error reports by a random amount of time between 0 and
60 seconds if multiple Michael MIC failures are detected with the same PTK
(i.e., the Authenticator does not rekey PTK on first failure report). This
is disabled by default and can be enabled with a build option
CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config.
This may help in making a chopchop attack take much longer time by forcing
the attacker to wait 60 seconds before knowing whether a modified frame
resulted in a MIC failure.
Previously, hardcoded identity in the network configuration skipped both
IMSI reading and PIN verification. This broke cases where PIN is needed for
GSM/UMTS authentication. Now, only IMSI reading is skipped if identity is
hardcoded.
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.
