9p: add missing end-of-options record for trans_fd

2007-11-06T14:02:53Z

The list of options that the fd transport accepts is missing end-of-options marker. This patch adds it. Signed-off-by: Latchesar Ionkov Acked-by: Eric Van Hensbergen

9p: return NULL when trans not found

2007-11-06T14:02:53Z

v9fs_match_trans function returns arbitrary transport module instead of NULL when the requested transport is not registered. This patch modifies the function to return NULL in that case. Signed-off-by: Latchesar Ionkov Acked-by: Eric Van Hensbergen

9p: add virtio transport

2007-10-23T18:47:31Z

This adds a transport to 9p for communicating between guests and a host using a virtio based transport. Signed-off-by: Eric Van Hensbergen

typo fixes

2007-10-19T23:34:40Z

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. Signed-off-by: Matt LaPlante Acked-by: Randy Dunlap Signed-off-by: Adrian Bunk

9p: remove sysctl

2007-10-17T19:35:15Z

A sysctl method was added to enable and disable debugging levels. After further review, it was decided that there are better approaches to doing this and the sysctl methodology isn't really desirable. This patch removes the sysctl code from 9p. Signed-off-by: Eric Van Hensbergen

9p: fix bad kconfig cross-dependency

2007-10-17T19:31:07Z

This patch moves transport dynamic registration and matching to the net module to prevent a bad Kconfig dependency between the net and fs 9p modules. Signed-off-by: Eric Van Hensbergen

9p: attach-per-user

2007-10-17T19:31:07Z

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=) 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 Signed-off-by: Eric Van Hensbergen

9p: Make transports dynamic

2007-10-17T19:31:07Z

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

9p: fix bad error path in conversion routines

When buf_check_overflow() returns != 0 we will hit kfree(ERR_PTR(err)) and it will not be happy about it. Signed-off-by: Mariusz Kozlowski Signed-off-by: Eric Van Hensbergen
