The new debug support lacks some of the information that the previous fcprint code provided -- this patch focuses on better presentation of debug data along with more helpful debug along error paths. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

One of the current debug options allows users to get a verbose dump of fcalls. This isn't really necessary as correctly parsed protocol frames can be printed as part of the code in the client functions. The consolidated printfcalls structure would require new entries to be added for every extension. This patch removes the debug print methods and their use.

Alsmot all 9P client wire functions have their own (set of) functions. Tversion is an exception as its encapsulated into the client_create code. This patch moves the protocol specifics of this to a function to match the rest of the code. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

Currently reading a directory is implemented in the client code. This function is not actually a wire operation, but a meta operation which calls read operations and processes the results. This patch moves this functionality to the fs layer and calls component wire operations instead of constructing their packets. This provides a cleaner separation and will help when we reorganize the client functions and protocol processing methods. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

There are a couple of methods in the client code which aren't actually wire operations. To keep things organized cleaner, these operations are being moved to the fs layer. This patch moves the readn meta-function (which executes multiple wire reads until a buffer is full) to the fs layer. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

Currently there are two separate versions of read and write. One for dealing with user buffers and the other for dealing with kernel buffers. There is a tremendous amount of code duplication in the otherwise identical versions of these functions. This patch adds an additional user buffer parameter to read and write and conditionalizes handling of the buffer on whether the kernel buffer or the user buffer is populated.

This code moves the rpc function to the common client base, reorganizes the flush code to be more simple and stable, and makes the necessary adjustments to the underlying transports to adapt to the new structure. This reduces the overall amount of code duplication between the transports and should make adding new transports more straightforward. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

The virtio transport uses a simplified request management system that I want to use for all transports. This patch adapts and moves the exisiting code for managing requests to the client common code. Later patches will apply these mechanisms to the other transports. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

Cleanup files by reordering functions in order to remove need for unnecessary function prototypes. There are no code changes here, just functions being moved around and prototypes being eliminated. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

Right now there is a transport module structure which provides per-transport type functions and data and a transport structure which contains per-instance public data as well as function pointers to instance specific functions. This patch moves public transport visible instance data to the client structure (which in some cases had duplicate data) and consolidates the functions into the transport module structure.

This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.

9p trans modules aren't refcounted nor were they unregistered properly. Fix it. * Add 9p_trans_module->owner and reference the module on each trans instance creation and put it on destruction. * Protect v9fs_trans_list with a spinlock. This isn't strictly necessary as the list is manipulated only during module loading / unloading but it's a good idea to make the API safe. * Unregister trans modules when the corresponding module is being unloaded. * While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().

Propagate changes that were made to the parse_options code to the other parse options pieces present in the other modules. Looks like the client parse options was probably corrupting the parse string and causing problems for others. Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step.

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: NLatchesar Ionkov <lucho@ionkov.net> Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p. It moves the transport, packet marshalling and connection layers to net/9p leaving only the VFS related files in fs/9p. This work is being done in preparation for in-kernel 9p servers as well as alternate 9p clients (other than VFS).
