Solaris Trusted Extensions Supports Mounting Labeled Filesystems With the NFSv3 Protocol

This security enhancement is new in the Developer 1/08 release.

Starting with this release, the Solaris Trusted Extensions software can mount labeled file systems by using NFS Version 3 (NFSv3) in addition to NFS Version 4 (NFSv4). Solaris Trusted Extensions has no restrictions in using TCP as an underlying transport protocol for NFS. However, users cannot choose UDP as the underlying protocol for read-down NFS access for NFSv3. The use of UDP for the initial mount operation is supported, but UDP is not supported for subsequent multilevel NFSv3 operations.
