Description

UDP is a deprecated transport protocol for NFS with v4 and above. It would probably be a good plan to review the requirements here. With v4.1 (set to be the new default from 7.4) far fewer ports are required than for 4.0 too. We should definitely try and sync up on what is currently done for the firewall though, and how we can keep in sync with NFS's requirements. Perhaps a good discussion point for the next nfs/net meeting. It might be worth considering to split nfs service into two regarding the nfs version. else UDP would be opened or additional manual UDP configration needed, where the latter seems worse to me.

This makes sense to me. I don't like opening UDP for the uncommon case. How about we add a nfs3 service definition that opens both TCP/UDP? Would that work for you Soumya?

That shall surely work. We as RHGS product support NFSv3 server over both UDP and TCP and hence this requirement. The current firewalld service named "nfs" handles only NFSv4 protocol. A new service "nfs3" definition to have udp port open sounds good to me. Thanks! Upstream commit

There's known issue with runtime rules management if you have both nfs and nfs3 enabled from permanent mode and decide to remove one of the services at runtime. Workaround is to have correct service enabled from permanent mode and apply it via `firewall-cmd --reload`. ref bug 1534571 about overlapping ports in service files. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
