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.)
