Topic: 9P2000


  
  USENIX '05 — Technical Paper, FREENIX Track
Implementing 9P2000 under Linux is a matter of mapping VFS operations to their associated 9P operations.
The Linux 9P2000 implementation seeks to preserve some of the atomicity of the original Plan 9 semantics by caching the fid in the inode structure - however, this does not guarantee the same atomic semantic.
While performance for static files isn’t a prime motivation for the 9P2000 protocol, we are confident that a loose consistency cache-layer similar to NFS could be implemented which would yield similar, if not better performance results.

 9P - The Plan 9 File Protocol   (Site not responding. Last check: 2007-10-21)
9P2000 is the latest version of the 9P protocol which was introduced with Plan 9 from Bell Labs 4th Edition; it introduced certain simplifications of the protocol.
Styx was a variant of the original 9P protocol for Inferno, most of those changes were rolled into 9P2000 and Inferno itself switched to use the new version of the protocol but keep the same name.
It is a set of extensions to 9P2000 as part of the v9fs project to support aspects of legacy Unix file systems that 9P never included because Plan 9 didn't need them(eg., SUID bit).

 9p - Article and Reference from OnPedia.com
The latest version of Inferno also uses 9P2000.
The Inferno file protocol was originally called Styx, but technically it has always been a variant of 9P.

 Styx revision
The original version of Styx was based on Plan 9's 9P, but stripped of things that were arguably inappropriate outside that environment.
Since then, 9P has changed to 9P2000, and although Walk is more complicated, the protocol has improvements that are attractive in the Inferno environment.
We are currently using Inferno with a Styx variant and device driver interface that is based on 9P2000.

 plan 9 from outer space… - csant/log - by Claudio Santambrogio
It presents a unified distributed resource sharing protocol that will be able to distribute devices, file systems, system services, and application interfaces.
It was revised for the 4th edition of Plan 9 under the name 9P2000.
The operating system Inferno is based on Plan 9, but both the original and the derivative product do not have a broad audience.

 Gmane -- Mail To News And Back Again
Hi everyone, we'd like to pre-announce our 9P2000 file system driver support for Linux in order to solicit comments/contributions/participation before we begin posting patches to the wider community.
BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) was a new research operating system and associated applications suite developed by the Computing Science Research Center of ATandT Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX, C, and C++.
The V9FS project (http://v9fs.sourceforge.net) is an attempt to bring Plan 9's unified approach to resource sharing to Linux and other operating systems via support for the 9P2000 resource sharing protocol.

 gmane.os.inferno.general
One of the advantages of 9P was that there existed a minimum message size which the protocol could support (~128 bytes).
Now for my question: inferno, when it negotiaties, won't accept a minimum packet size of less than 256 bytes; however, devmnt doesn't appear to enforce this size in a meaningful way.
It would almost be better to negotiate MAXWELEM and a maximum string length when setting up a connection to enable 9P like behavior within 9P2000.

* 9P2000 is a synchronous resource sharing protocol intended to allow sharing of devices and other system resources as well as files.
* 9P2000 is used by Plan 9 applications to expose synethetic file systems which are used to interact with the applications.

 Plan 9 Remote Resource Protocol Unix Extension
If the server agrees to 9P2000.u, then the wire protocol that follows is 9P2000 with these changes.
Support for 9P2000.u is an optional extension which isn't quite covered in the existing version semantics for 9P2000.
There are four new fields in the stat structure supporting 9P2000 extensions - as well as new qid.type bits and mode bits.

Ruby-IXP is an implementation of the 9P2000 protocol designed for use with Window Manager Improved.
It is written in pure Ruby to avoid periodical calling of the wmiir command, thus improving performance.
There is another full-blown 9P2000 implementation called Rstyx, but it's rather complex and slow.

The module name itself was 9p2000, and the file system type was 9P.
This patch attempts to clean that up, changing all references to 9p in order to match the directory name.
There is also a minor consistency cleanup in the options changing the name option to uname in order to more closely match the Plan 9 options.

The undocumented `noauth' configuration console command does not affect the 9P2000 side of things.
Had I realised in time, I'd have made the above change, and just in case that wasn't enough, I'd have opened a few more windows with the file server mounted.
