Hello, I would like to discuss the status and next steps for completing richacl support (http://en.wikipedia.org/wiki/Richacls) in the vfs, local file systems, nfs, cifs. Right now, we don't have kernel support for a file permission model powerful enough to support both POSIX permissions and NFSv4 / CIFS access control lists at the same time. As a result, support for the NFSv4 and CIFS permission models is very limited, and permission wise, Linux is neither a very good client nor server to other systems. For example, the permission to only append to a file or to take ownership of a file cannot be represented. When files are copied across systems, file permissions change or are lost. This should be improved. I've started working on this a long time ago but didn't have enough time to complete it. More recently, Aneesh Kumar has spent time on this topic (http://lwn.net/Articles/596517/) but eventually also stopped working on it. Things have improved on my side and I'll be able to work on this again now, though.
