Internal error during EAP-FAST

Sebastian
Hi *,

I try to do an 802.1x authentication of Cisco access points on Aruba
switches against Freeradius 3.0.21-1 under Debian 10.6.

The APs prefer to do EAP-FAST so I enabled the relevant parts in
modules-enabled/eap but whenever a EAP-FAST request arrives now, it
throws this:
(2) eap: Calling submodule eap_fast to process data
(2) eap_fast: Authenticate
(2) eap_fast: Continuing EAP-TLS
(2) eap_fast: [eaptls verify] = ok
(2) eap_fast: Done initial handshake
(2) eap_fast: (other): before SSL initialization
(2) eap_fast: >>> send TLS 1.3  [length 0002]
(2) eap_fast: ERROR: TLS Alert write:fatal:internal error
tls: TLS_accept: Error in error
(2) eap_fast: ERROR: Failed in __FUNCTION__ (SSL_read):
error:141FC044:SSL routines:tls_setup_handshake:internal error
(2) eap_fast: ERROR: System call (I/O) error (-1)
(2) eap_fast: ERROR: TLS receive handshake failed during operation
(2) eap_fast: ERROR: [eaptls process] = fail
(2) eap: ERROR: Failed continuing EAP FAST (43) session.  EAP sub-module failed

I tried to change tls_max_version from 1.2 to 1.3 but that didn't
change anything.

Is there anything I can do here or is this an issue with OpenSSL
(1.1.1d-0+deb10u3)?

Thanks
Sebastian

  There is no standard for using TLS 1.3 with *any* EAP method.

  The EAP-FAST implementation in FreeRADIUS uses only TLS 1.1.

  Change it to 1.1.

Re: Internal error during EAP-FAST

Ah, I read that it doesn't support 1.3 (that's why I had 1.2 set) but
I missed the note about 1.2/1.1. Thanks.

So now freeradius sends a response, but it still ends up with:

(2) eap: Calling submodule eap_fast to process data
(2) eap_fast: Authenticate
(2) eap_fast: Continuing EAP-TLS
(2) eap_fast: [eaptls verify] = ok

(2) eap: ERROR: Failed continuing EAP FAST (43) session.  EAP sub-module failed
(2) eap: Sending EAP Failure (code 4) ID 209 length 4

cipher_list is set to "ALL:!EXPORT:!eNULL:!SSLv2@SECLEVEL=0" in fast
{...} and "ALL:!EXPORT:!eNULL:!SSLv2" in tls-config tls-common { ...}
as the comments in mods-available/eap suggest.

Does that mean that the access point insists on a newer version of TLS?

Thanks
Sebastian

  The other end is trying to negotiate TLS 1.3.  This is wrong.

  Then cipher list is different from the TLS version.

> Does that mean that the access point insists on a newer version of TLS?

  No.  It means that the end user system (laptop, desktop, etc.) is trying to use TLS 1.3

  If the other end says that it wants to use TLS 1.3 and nothing else, then that's it.  All FreeRADIUS can do is stop doing EAP.

  Fix the end user system so that it doesn't ry to negotiate TLS 1.3.  Again, there is *no standard* defined for this.  I've been working with the IETF, hostap, and Microsoft in order to get (a) the standards written, and (b) verified interoperability.

  Once that's done, people will be able to use TLS 1.3.  Until then, don't use it.  And any system which tries to use it is *broken*.

Re: Internal error during EAP-FAST

Sebastian
Well, it's not a desktop or laptop, it's the Cisco access point itself
(the AP tries to authenticate on the switch port) and I don't have a
lot of options to set there – basically just what kind of EAP I want
and that's it.
(EAP-PEAP aborts after it receives a NAK  and EAP-TLS never receives a
reply to it's Access-Challenge - that's why I hoped that at least
EAP-FAST would work …)

But thank you for your help – I will double-check if I can change the
requested TLS version somehow.

Best regards
Sebastian
