* [PATCH] v9fs: readlink extended mode checkEric Van Hensbergen2005-09-091-5/+30
| | | | | | | | | | | | LANL reported some issues with random crashes during mount of legacy protocol servers (9P2000 versus 9P2000.u) -- crash was always happening in readlink (which should never happen in legacy mode). Added some sanity conditionals to the get_inode code which should prevent the errors LANL was seeing. Code tested benign through regression.

It can be used to share all sorts of resources: static files, synthetic file servers (such as /proc or /sys), devices, and application file servers (such as FUSE). BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) is a research operating system and associated applications suite developed by the Computing Science Research Center of AT&T Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX , C, and C++. Plan 9 was initially released in 1993 to universities, and then made generally available in 1995. Its core operating systems code laid the foundation for the Inferno Operating System released as a product by Lucent Bell-Labs in 1997. The Inferno venture was the only commercial embodiment of Plan 9 and is currently maintained as a product by Vita Nuova (http://www.vitanuova.com). After updated releases in 2000 and 2002, Plan 9 was open-sourced under the OSI approved Lucent Public License in 2003. The Plan 9 project was started by Ken Thompson and Rob Pike in 1985. Their intent was to explore potential solutions to some of the shortcomings of UNIX in the face of the widespread use of high-speed networks to connect machines. In UNIX, networking was an afterthought and UNIX clusters became little more than a network of stand-alone systems. Plan 9 was designed from first principles as a seamless distributed system with integrated secure network resource sharing. Applications and services were architected in such a way as to allow for implicit distribution across a cluster of systems. Configuring an environment to use remote application components or services in place of their local equivalent could be achieved with a few simple command line instructions. For the most part, application implementations operated independent of the location of their actual resources. Commercial operating systems haven't changed much in the 20 years since Plan 9 was conceived. Network and distributed systems support is provided by a patchwork of middle-ware, with an endless number of packages supplying pieces of the puzzle. Matters are complicated by the use of different complicated protocols for individual services, and separate implementations for kernel and application resources. 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. V9FS HISTORY V9FS was originally developed by Ron Minnich and Maya Gokhale at Los Alamos National Labs (LANL) in 1997. In November of 2001, Greg Watson setup a SourceForge project as a public repository for the code which supported the Linux 2.4 kernel. About a year ago, I picked up the initial attempt Ron Minnich had made to provide 2.6 support and got the code integrated into a 2.6.5 kernel. I then went through a line-for-line re-write attempting to clean-up the code while more closely following the Linux Kernel style guidelines. I co-authored a paper with Ron Minnich on the V9FS Linux support including performance comparisons to NFSv3 using Bonnie and PostMark - this paper appeared at the USENIX/FREENIX 2005 conference in April 2005: ( http://www.usenix.org/events/usenix05/tech/freenix/hensbergen.html ). CALL FOR PARTICIPATION/REQUEST FOR COMMENTS Our 2.6 kernel support is stabilizing and we'd like to begin pursuing its integration into the official kernel tree. We would appreciate any review, comments, critiques, and additions from this community and are actively seeking people to join our project and help us produce something that would be acceptable and useful to the Linux community. STATUS The code is reasonably stable, although there are no doubt corner cases our regression tests haven't discovered yet. It is in regular use by several of the developers and has been tested on x86 and PowerPC (32-bit and 64-bit) in both small and large (LANL cluster) deployments. Our current regression tests include fsx, bonnie, and postmark. It was our intention to keep things as simple as possible for this release -- trying to focus on correctness within the core of the protocol support versus a rich set of features. For example: a more complete security model and cache layer are in the road map, but excluded from this release. Additionally, we have removed support for mmap operations at Al Viro's request. PERFORMANCE Detailed performance numbers and analysis are included in the FREENIX paper, but we show comparable performance to NFSv3 for large file operations based on the Bonnie benchmark, and superior performance for many small file operations based on the PostMark benchmark. Somewhat preliminary graphs (from the FREENIX paper) are available (http://v9fs.sourceforge.net/perf/index.html). RESOURCES The source code is available in a few different forms: tarballs: http://v9fs.sf.net CVSweb: http://cvs.sourceforge.net/viewcvs.py/v9fs/linux-9p/ CVS: :pserver:anonymous@cvs.sourceforge.net:/cvsroot/v9fs/linux-9p Git: rsync://v9fs.graverobber.org/v9fs (webgit: http://v9fs.graverobber.org) 9P: tcp!v9fs.graverobber.org!6564 The user-level server is available from either the Plan 9 distribution or from http://v9fs.sf.net Other support applications are still being developed, but preliminary version can be downloaded from sourceforge. Documentation on the protocol has historically been the Plan 9 Man pages (http://plan9.bell-labs.com/sys/man/5/INDEX.html), but there is an effort under way to write a more complete Internet-Draft style specification (http://v9fs.sf.net/rfc). There are a couple of mailing lists supporting v9fs, but the most used is v9fs-developer@lists.sourceforge.net -- please direct/cc your comments there so the other v9fs contibutors can participate in the conversation.

* [PATCH] files: lock-free fd look-upDipankar Sarma2005-09-093-19/+27
| | | | | | | | | | | | With the use of RCU in files structure, the look-up of files using fds can now be lock-free. The lookup is protected by rcu_read_lock()/rcu_read_unlock().

* [PATCH] files: files struct with RCUDipankar Sarma2005-09-095-150/+303
| | | | | | | | | | | | | | | | | | | | | Patch to eliminate struct files_struct.file_lock spinlock on the reader side and use rcu refcounting rcuref_xxx api for the f_count refcounter. The updates to the fdtable are done by allocating a new fdtable structure and setting files->fdt to point to the new structure. The fdtable structure is protected by RCU thereby allowing lock-free lookup. For fd arrays/sets that are vmalloced, we use keventd to free them since RCU callbacks can't sleep. A global list of fdtable to be freed is not scalable, so we use a per-cpu list. If keventd is already handling the current cpu's work, we use a timer to defer queueing of that work. Since the last publication, this patch has been re-written to avoid using explicit memory barriers and use rcu_assign_pointer(), rcu_dereference() premitives instead. This required that the fd information is kept in a separate structure (fdtable) and updated atomically.

* [PATCH] files: break up files structDipankar Sarma2005-09-098-63/+104
| | | | | | | | | | | | | | | In order for the RCU to work, the file table array, sets and their sizes must be updated atomically. Instead of ensuring this through too many memory barriers, we put the arrays and their sizes in a separate structure. This patch takes the first step of putting the file table elements in a separate structure fdtable that is embedded withing files_struct. It also changes all the users to refer to the file table using files_fdtable() macro. Subsequent applciation of RCU becomes easier after this.

* [PATCH] move truncate_inode_pages() into ->delete_inode()Mark Fasheh2005-09-091-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow file systems supporting ->delete_inode() to call truncate_inode_pages() on their own. OCFS2 wants this so it can query the cluster before making a final decision on whether to wipe an inode from disk or not. In some corner cases an inode marked on the local node via voting may not actually get orphaned. A good example is node death before the transaction moving the inode to the orphan dir commits to the journal. Without this patch, the truncate_inode_pages() call in generic_delete_inode() would discard valid data for such inodes. During earlier discussion in the 2.6.13 merge plan thread, Christoph Hellwig indicated that other file systems might also find this useful. IMHO, the best solution would be to just allow ->drop_inode() to do the cluster query but it seems that would require a substantial reworking of that section of the code. Assuming it is safe to call write_inode_now() in ocfs2_delete_inode() for those inodes which won't actually get wiped, this solution should get us by for now. Trivial testing of this patch (and a related OCFS2 update) has shown this to avoid the corruption I'm seeing.
