memcached and TLS resumption

28 Mar 2024

      Hi all,

I’m trying to use memcached to do TLS session resumption. (FreeRad 3.2.1, Debian 11)

What works:

  *   eap-tls authentication (with OCSP)
  *   tls session resumption works with a local cache – entries are created and then referenced correctly (if I define persist_dir in eap/cache)
  *   I see an connections to (local) memcached daemon initialising at FreeRad startup

But nothing gets written to Memcached. I’ve tried adding driver = “rlm_cache_memcached” to eap/cache (freeradius -Xxx says its unused). It looks to me like the standard rlm_cache and the eap/cache are unrelated – is this correct? (and then there is cache_eap…). Any pointers as to what I am missing here would be great.

Thanks,

Jim

(And so a plan B - if I were to use a shared NFS filesystem for the cache directory, would that be a disaster?)

Snippets from logs:

TLS session cache working (with persist_dir set):
  (7) eap_tls: Saving session a741a601f013b74e7123f559e1b4d8ab9b80ef8d923132c0be0f6c62a441c80e in the disk cache
And resumption:
  (9) eap_tls: Peer requested cached session: a741a601f013b74e7123f559e1b4d8ab9b80ef8d923132c0be0f6c62a441c80e reading pairlist file /etc/freeradius/3.0/tlscache/a741a601f013b74e7123f559e1b4d8ab9b80ef8d923132c0be0f6c62a441c80e.vps

TLS session cache not working (no mention if memcach’ing):
  (7) eap_tls:     caching TLS-Client-Cert-X509v3-Extended-Key-Usage-OID += "1.3.6.1.5.5.7.3.2"
  (7) eap_tls: Failed to find 'persist_dir' in TLS configuration.  Session will not be cached on disk.
  (7) eap: Sending EAP Success (code 3) ID 178 length 4
