| * 9p: add more conservative lockingEric Van Hensbergen2008-10-171-7/+17
| | | | | | | | | | | | | | | | | | During the reorganization some of the multi-theaded locking assumptions were accidently relaxed. This patch moves us back towards a more conservative locking strategy. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: fix oops in protocol stat parsing error path.Eric Van Hensbergen2008-10-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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>
| * 9p: Improve debug supportEric Van Hensbergen2008-10-172-27/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: eliminate depricated conv functionsEric Van Hensbergen2008-10-173-1055/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * 9p: rework client code to use new protocol support functionsEric Van Hensbergen2008-10-175-515/+572
| | | | | | | | | | | | | | | | | | | | Now that the new protocol functions are in place, this patch switches the client code to using the new support code. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: remove unnecessary tag field from p9_req_t structureEric Van Hensbergen2008-10-171-1/+1

| * 9p: remove 9p fcall debug printsEric Van Hensbergen2008-10-174-385/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: add new protocol support codeEric Van Hensbergen2008-10-173-0/+489
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: encapsulate version functionEric Van Hensbergen2008-10-171-30/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: move dirread to fs layerEric Van Hensbergen2008-10-171-103/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * 9p: move readn meta-function from client to fs layerEric Van Hensbergen2008-10-171-26/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * 9p: consolidate read/write functionsEric Van Hensbergen2008-10-171-122/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: drop broken unused error path from p9_conn_create()Tejun Heo2008-10-171-16/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p: make rpc code common and rework flush codeEric Van Hensbergen2008-10-173-307/+311
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * 9p: use the rcall structure passed in the request in trans_fd read_workEric Van Hensbergen2008-10-171-63/+66
| | | | | | | | | | | | | | | | | | This patch reworks the read_work function to enable it to directly use a passed in rcall structure. This should help allow us to remove unnecessary copies in the future. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: apply common request code to trans_fdEric Van Hensbergen2008-10-173-171/+117

| * 9p: move request management to client codeEric Van Hensbergen2008-10-172-127/+161
| | | | | | | | | | | | | | | | | | | | 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.

| * 9p: eliminate callback complexityEric Van Hensbergen2008-10-171-83/+66
| | | | | | | | | | | | | | | | | | | | The current trans_fd rpc mechanisms use a dynamic callback mechanism which introduces a lot of complexity which only accomodates a single special case. This patch removes much of that complexity in favor of a simple exception mechanism to deal with flushes. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: consolidate mux_rpc and request structureEric Van Hensbergen2008-10-171-46/+22
| | | | | | | | | | | | | | | | | | | | Currently, trans_fd has two structures (p9_req and p9_mux-rpc) which contain mostly duplicate data. This patch consolidates these two structures and removes p9_mux_rpc. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: remove unnecessary prototypesEric Van Hensbergen2008-10-172-548/+495
| | | | | | | | | | | | | | | | | | | | | | 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: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: remove duplicate client stateEric Van Hensbergen2008-10-171-15/+11
| | | | | | | | | | | | | | | | Now that we are passing client state into the transport modules, remove duplicate state which is present in transport private structures. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * 9p: consolidate transport structureEric Van Hensbergen2008-10-174-157/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 9p-trans_fd: use single pollerTejun Heo2008-10-171-166/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The send marshaling code split a particular dprintk across two lines, which makes it hard to extract from logfiles. Signed-off-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| | * | RPC/RDMA: harden connection logic against missing/late rdma_cm upcalls.Tom Talpey2008-10-102-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add defensive timeouts to wait_for_completion() calls in RDMA address resolution, and make them interruptible. Fix the timeout units to milliseconds (formerly jiffies) and move to private header. Signed-off-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| | * | RPC/RDMA: fix connect/reconnect resource leak.Tom Talpey2008-10-101-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPC/RDMA code can leak RDMA connection manager endpoints in certain error cases on connect. Don't signal unwanted events, and be certain to destroy any allocated qp. Signed-off-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| | * | RPC/RDMA: return a consistent error, when connect fails.Tom Talpey2008-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xprt_connect call path does not expect such errors as ECONNREFUSED to be returned from failed transport connection attempts, otherwise it translates them to EIO and signals fatal errors. For example, mount.nfs prints simply "internal error". Translate all such errors to ENOTCONN from RPC/RDMA to match sockets behavior.

| | * | RPC/RDMA: adhere to protocol for unpadded client trailing write chunks.Tom Talpey2008-10-103-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPC/RDMA protocol allows clients and servers to avoid RDMA operations for data which is purely the result of XDR padding. On the client, automatically insert the necessary padding for such server replies, and optionally don't marshal such chunks.
