2008-11-05p9: Fix leak of waitqueue in request allocation pathTom Tucker
If a T or R fcall cannot be allocated, the function returns an error but neglects to free the wait queue that was successfully allocated. If it comes through again a second time this wq will be overwritten with a new allocation and the old allocation will be leaked. Also, if the client is subsequently closed, the close path will attempt to clean up these allocations, so set the req fields to NULL to avoid duplicate free.

2008-11-059p: rdma: Set trans prior to requesting async connection opsTom Tucker

2008-10-179p: fix oops in protocol stat parsing error path.Eric Van Hensbergen
When we get an error on parsing a stat due to a protocol bug, we can generate an oops during cleanup because we didn't initialize the string pointers in the stat structure. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: Improve debug supportEric Van Hensbergen

2008-10-179p: eliminate depricated conv functionsEric Van Hensbergen
Remove depricated conv functions which have been replaced with new protocol routines. This patch also reworks the one instance of the file-system code which directly calls conversion routines (to accomplish unpacking dirreads). Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: rework client code to use new protocol support functionsEric Van Hensbergen

2008-10-179p: remove 9p fcall debug printsEric Van Hensbergen
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. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: add new protocol support codeEric Van Hensbergen
This adds a new protocol processing support code based on Anthony Liguori's 9p library code. This code performs protocol marshalling/unmarshalling using printf like strings to represent protocol elements. It is my intent to use them to replace the current functions in conv.c as well as the p9_create_* functions. This should make the client implementation much more clear, and also make it much easier to add new protocol extensions by limiting the number of places in which changes need to be made. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: encapsulate version functionEric Van Hensbergen
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: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: move dirread to fs layerEric Van Hensbergen
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: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: move readn meta-function from client to fs layerEric Van Hensbergen
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: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: consolidate read/write functionsEric Van Hensbergen
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.

2008-10-179p: drop broken unused error path from p9_conn_create()Tejun Heo
Post p9_fd_poll() error path which checks m->poll_waddr[i] for PTR_ERR value has the following problems. * It's completely unused. Error value is set iff NULL @wait_address has been specified to p9_pollwait() which is guaranteed not to happen. * It dereferences @m after deallocating it (introduced by 571ffeaf and spotted by Raja R Harinath. * It returned the wrong value on error. It should return poll_waddr[i] but it returnes poll_waddr (introduced by 571ffeaf). * p9_mux_poll_stop() doesn't handle PTR_ERR value. It will try to operate on the PTR_ERR value as if it's a normal pointer and cause oops. As the error path is bogus in the first place, there's no reason to hold onto it. Kill it.

2008-10-179p: make rpc code common and rework flush codeEric Van Hensbergen
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: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: use the rcall structure passed in the request in trans_fd read_workEric Van Hensbergen

2008-10-179p: move request management to client codeEric Van Hensbergen
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: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-179p: eliminate callback complexityEric Van Hensbergen
The current trans_fd rpc mechanisms use a dynamic callback mechanism which introduces a lot of complexity which only accomodates a single special case.

2008-10-179p: consolidate mux_rpc and request structureEric Van Hensbergen

2008-10-179p: consolidate transport structureEric Van Hensbergen
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.

2008-10-179p-trans_fd: use single pollerTejun Heo
trans_fd used pool of upto 100 pollers to monitor the r/w fds. The approach makes sense in userspace back when the only available interfaces were poll(2) and select(2). As each event monitor - trigger - handling iteration took O(n) where `n' is the number of watched fds, it makes sense to spread them to many pollers such that the `n' can be divided by the number of pollers. However, this doesn't make any sense in kernel because persistent edge triggered event monitoring is how the whole thing is implemented in the kernel in the first place. This patch converts trans_fd to use single poller which watches all the fds instead of the poll of pollers approach. All the fds are registered for monitoring on creation and only the fds with pending events are scanned when something happens much like how epoll is implemented. This change makes trans_fd fd monitoring more efficient and simpler. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-10-13vfs: Use const for kernel parser tableSteven Whitehouse
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.

2008-09-249p-trans_fd: fix trans_fd::p9_conn_destroy()Tejun Heo
p9_conn_destroy() first kills all current requests by calling p9_conn_cancel(), then waits for the request list to be cleared by waiting on p9_conn->equeue. After that, polling is stopped and the trans is destroyed. This sequence has a few problems. * Read and write works were never cancelled and the p9_conn can be destroyed while the works are running as r/w works remove requests from the list and dereference the p9_conn from them. * The list emptiness wait using p9_conn->equeue wouldn't trigger because p9_conn_cancel() always clears all the lists and the only way the wait can be triggered is to have another task to issue a request between the slim window between p9_conn_cancel() and the wait, which isn't safe under the current implementation with or without the wait. This patch fixes the problem by first stopping poll, which can schedule r/w works, first and cancle r/w works which guarantees that r/w works are not and will not run from that point and then calling p9_conn_cancel() and do the rest of destruction.

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().

2008-05-149p: fix error path during early mountEric Van Hensbergen
There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd transport separate from the core 9pnet code seemed like a good idea at the time, but in practice has caused more harm and confusion than good.
