| | | | | | | quick pass to update the documentation to include instructions for the new cache=mmap mode as well as clean up some out-of-date bits. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: fix 9p.txt to advertise msize instead of maxdataNicolae Mogoreanu2011-10-241-1/+1
| | | | | | | | | 9p.txt advertises that maxdata mount option should be used to specify msize, in the code though we use msize option and completely ignore maxdata if passed Signed-off-by: Nicolae Mogoreanu <mogoreanu@gmail.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

* Documentation: update broken web addresses.Justin P. Mattock2010-08-041-1/+1
| | | | | | | | | | | | | | | | | | Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

* typo fixesMatt LaPlante2007-10-201-1/+1
| | | | | | | | | | | | Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

* 9p: attach-per-userLatchesar Ionkov2007-10-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: rename uid and gid parametersLatchesar Ionkov2007-10-171-2/+2
| | | | | | | | | | Change the names of 'uid' and 'gid' parameters to the more appropriate 'dfltuid' and 'dfltgid'. This also sets the default uid/gid to -2 (aka nfsnobody) Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: Make transports dynamicEric Van Hensbergen2007-10-171-4/+4
| | | | | | | | | This patch abstracts out the interfaces to underlying transports so that new transports can be added as modules. This should also allow kernel configuration of transports without ifdef-hell. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: update maintainers and documentationEric Van Hensbergen2007-08-231-5/+19
| | | | | | | | | Updates to the MAINTAINERS file and documentation for 9p to point to the swik wiki versus the outdated sf.net page. Also updated some email addresses and added pointers to papers which better describe the implementation and application of the Linux 9p client. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: implement optional loose read cacheEric Van Hensbergen2007-02-181-0/+4
| | | | | | | | | | | | | | | While cacheing is generally frowned upon in the 9p world, it has its place -- particularly in situations where the remote file system is exclusive and/or read-only. The vacfs views of venti content addressable store are a real-world instance of such a situation. To facilitate higher performance for these workloads (and eventually use the fscache patches), we have enabled a "loose" cache mode which does not attempt to maintain any form of consistency on the page-cache or dcache. This results in over two orders of magnitude performance improvement for cacheable block reads in the Bonnie benchmark. The more aggressive use of the dcache also seems to improve metadata operational performance. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

* [PATCH] 9p: fix name consistency problemsEric Van Hensbergen2006-03-251-0/+99
There were a number of conflicting naming schemes used in the v9fs project. The directory was fs/9p, but MAINTAINERS and Documentation referred to v9fs. 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. We'll also start using 9p instead of v9fs as our patch prefix. 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.
