Automatic regression and interoperability testing of wpa_supplicant's
|
|
IEEE 802.1X/EAPOL authentication
|
|
|
|
Test program:
|
|
- Linked some parts of IEEE 802.1X Authenticator implementation from
|
|
hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS
|
|
encapsulation/decapsulation) into wpa_supplicant.
|
|
- Replaced wpa_supplicant.c and wpa.c with test code that trigger
|
|
IEEE 802.1X authentication automatically without need for wireless
|
|
client card or AP.
|
|
- For EAP methods that generate keying material, the key derived by the
|
|
Supplicant is verified to match with the one received by the (now
|
|
integrated) Authenticator.
|
|
|
|
The full automated test suite can now be run in couple of seconds, but
|
|
I'm more than willing to add new RADIUS authentication servers to make
|
|
this take a bit more time.. ;-) As an extra bonus, this can also be
|
|
seen as automatic regression/interoperability testing for the RADIUS
|
|
server, too.
|
|
|
|
In order for me to be able to use a new authentication server, the
|
|
server need to be available from Internet (at least from one static IP
|
|
address) and I will need to get suitable user name/password pairs,
|
|
certificates, and private keys for testing use. Other alternative
|
|
would be to get an evaluation version of the server so that I can
|
|
install it on my own test setup. If you are interested in providing
|
|
either server access or evaluation version, please contact me
|
|
(j@w1.fi).

1) PEAPv1 required new label, "client PEAP encryption" instead of "client EAP
|
|
encryption", during key derivation (requires phase1="peaplabel=1" in the
|
|
network configuration in wpa_supplicant.conf)
|
|
2) used FreeRADIUS as inner auth server
|
|
5) PEAPv1 required termination of negotiation on tunneled EAP-Success and new
|
|
label in key deriviation
|
|
(phase1="peap_outer_success=0 peaplabel=1") (in "IETF Draft 5" mode)
|
|
6) Authenticator simulator required patching for handling Access-Accept within
|
|
negotiation (for the first EAP-Success of LEAP)
|
|
7) tested only with an older (incompatible) draft of EAP-PSK; FreeRADIUS does
|
|
not support the current EAP-PSK (RFC) specification
|
|
8) PEAPv1 used non-standard version negotiation (client had to force v1 even
|
|
though server reported v0 as the highest supported version)
|
|
9) only EAP-TTLS/EAP-TNC tested, i.e., test did not include proper sequence of
|
|
client authentication followed by TNC inside the tunnel
|
|
10) worked only with special compatibility code to match the IKEv2 server
|
|
implementation

(Server rejects authentication without any reason in debug log. It
|
|
looks like the inner TLS negotiation starts properly and the last
|
|
packet from Supplicant looks like the one sent in the Phase 1. The
|
|
server generates a valid looking reply in the same way as in Phase
|
|
1, but then ends up sending Access-Reject. Maybe an issue with TTLS
|
|
fragmentation in the Aegis server(?) The packet seems to include
|
|
1328 bytes of EAP-Message and this may go beyond the fragmentation
|
|
limit with AVP encapsulation and TLS tunneling. Note: EAP-PEAP/TLS
|
|
did work, so this issue seems to be with something TTLS specific.)
