Other NFS Changes
Three additional features have been added to NFS:
• Loopback transport support has been added to transport-independent
RPC.
• Automatic user-space thread generation has been enabled in the RPC
library.
• NFS server-side performance enhancements have been added.
Loopback Transport Support
Loopback transport provider devices (tlclts, tlcots, and tlcotsod)
have been added to the TI-RPC definitionfile, /etc/netconfig. Also, the
system will now have the following new loopback transport-specific
directories and files:
/etc/net/ loopback_transport_name /hosts
/etc/net/ loopback_transport_name /services
The following ONC/NFS daemons support loopback transport requests:
• /usr/sbin/rpcbind
• /usr/sbin/keyserv
• /usr/sbin/rpc.nisd
• /usr/sbin/nis_cachemgr
The netid and address fields in the rpcinfo call (which queries
/usr/sbin/rpcbind to determine what services have been registered)
now give the loopback device name plus an address name, rather than
the netbuf address provided by udp and tcp transport.
Additionally, the ticlts loopback transport device has a randomly
generated string address.
User-Space Threads
The svc_run() function call in the RPC library automatically generates
a thread on behalf of the application to process incoming RPC requests.
