This allows the EAP tests to pass, but the fix really needs to be in
hostapd itself. Hostapd currently tries to lookup the EAP session
immediately after receiving EAPOL_REAUTH. This uses the identity
it has stored which, in the case of PEAP/TTLS, will always be a phase2
identity. During this initial lookup hostapd hard codes the identity
to be phase1 which is not true for PEAP/TTLS, and the lookup fails.
This tests all EAP methods in their standard configuration. Any
corner cases requiring changes to main.conf or other hostapd
options are not included and will be left as stand alone tests.
This was done because nearly all EAP tests are identical except
the IWD provisioning file and hostapd EAP users fine. The IWD
provisioning file can be swapped out as needed for each individual
test without actually restarting IWD. And the EAP users file can
simply be written to include every possible EAP method that
is supported.
This also tests multiple agent requests for one network connection
because the TTLS client private key is not in the config file and the
MSCHAPV2 password is not in the config file.
Make 3 connections in test EAP-TLS, one with an unencrypted private key,
one with the private key passphrase provided in the provisioning file
and one with the passphrase provided through the agent. Also improve
the scanning logic at the beginning.
Unfortunately this doesn't currently ensure that the preauthentication
has succeeded and that later the PMKSA from the preauthentication was
used in the transition, only that the preauthentication process doesn't
break the transition. For now this can be confirmed by looking at the
testrunner -v output to see that the line "EAP completed with eapSuccess"
appears before the following line, and not after:
src/device.c:device_enter_state() Old State: connected, new state: roaming
