nfsd, rpcbind: add -P option to support pidfile path

2025-06-09T15:24:07Z

The -P option, when specified opens a pidfile to a given path. Both daemons also install a default pid file to the corresponding locations, that is, /var/run/nfsd.pid and /var/run/rpcbind.pid.

nfsd.8: Note that the -n option is deprecated

2025-03-10T13:35:23Z

PR#284616 reported that --maxthreads did not obey the 256 thread limit defined as MAXNFSDCNT in nfsd.c. This is actually a feature and not a bug, since many NFS servers will now want to run more than 256 threads and --maxthreads can be used to set the upper bound on the number of threads. (MAXNFSDCNT was used long ago to define how many daemons would be forked, before daemons were replaced by kernel threads.) However, the nfsd.8 man page was misleading, since it indicated that "-n" was the equivalent to setting both --minthreads and --maxthreads to the same value. This patch fixes the man page.

nfsd.c: Synchronize error handling

2024-09-29T20:11:54Z

Synchronize the error handling in nfsd. If you check other error handlings in those same condition blocks, it uses nfsd_exit instead, which will call killchildren() and call the rpcbind service to do the service un-mapping.

nfsd.8: Document ways to minimize Copy operation times

2024-03-18T22:40:41Z

For NFSv4.2, a Copy operation can take a long time to complete. If there is a concurrent ExchangeID or DelegReturn operation which requires the exclusive lock on all NFSv4 state, this can result in a stall of the nfsd server. This patch documents ways to avoid this problem. This is a content change.
