Add TLS version to logs with linelog in FreeRADIUS 3.2.4

14 Jun 2024

      Hi guys

A few weeks back, I used FreeRADIUS 3.0.26 on Ubuntu 22.04.4 LTS before upgrading to FreeRADIUS 3.2.4 (NetworkRADIUS packages). Everything works great so far, except two attributes are missing in our logs since then: TLS-Session-Version and TLS-Session-Cipher-Suite.

My /etc/freeradius/mods-available/linelog configuration looked like this on FreeRADIUS 3.0.x:

sp {
      Access-Accept = "%t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})"
}

When I start the debugging (see full output below), I can see the following attributes, which I could use / log now:

(10) eap_peap:   TLS-Session-Cipher-Suite = "ECDHE-RSA-AES256-GCM-SHA384"
(10) eap_peap:   TLS-Session-Version = "TLS 1.2"

When I try to “access” them in the linelog configuration like this…

   sp {
      Access-Accept = "%t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Test=%{%{eap_peap:TLS-Session-Version}:-NULL} TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})"
   }
}

…I get the following error in the debug output:

(21) 802.1x_authz_log: ERROR: %t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Test=%{%{eap_peap:TLS-Session-Version}:-NULL} TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})
(21) 802.1x_authz_log: ERROR:                                                                                    ^ Unknown module

Any hint, how I can “access” those two attributes in FreeRADIUS 3.2.4 correctly?

(10) eap_peap:   TLS-Session-Cipher-Suite = "ECDHE-RSA-AES256-GCM-SHA384"
(10) eap_peap:   TLS-Session-Version = "TLS 1.2"

Thanks in advance and best regards
Dominic
