Versions Affected : All verisons prior to FreeNAS 11.3-U2.1

---

Description

A change in rpc.rquotad made it send RQUOTA v2 requests instead of RQUOTA v1 requests.

Some vendors would send RPC_PROGNOTREGISTERED (“Program Not Registered”) response instead of the desired RPC_PROGVERSMISMATCH (“Program Version Mismatch”) response, preventing the mechanism from working.

---

Workaround

No workaround is available. Systems not using quotas on NFS mounted file systems are unaffected.

---

Mitigation

• Upgrade to FreeNAS 11.3-U3.2 or later
