* 9p: fix readdir corner casesEric Van Hensbergen2009-11-021-3/+2
| | | | | | | | | | | | | | | | | | The patch below also addresses a couple of other corner cases in readdir seen with a large (e.g. 64k) msize. I'm not sure what people think of my co-opting of fid->aux here. I'd be happy to rework if there's a better way. When the size of the user supplied buffer passed to readdir is smaller than the data returned in one go by the 9P read request, v9fs_dir_readdir() currently discards extra data so that, on the next call, a 9P read request will be issued with offset < previous offset + bytes returned, which voilates the constraint described in paragraph 3 of read(5) description. This patch preseves the leftover data in fid->aux for use in the next call. Signed-off-by: Jim Garlick <garlick@llnl.gov> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* virtio: let header files include virtio_ids.hChristian Borntraeger2009-10-221-1/+0
| | | | | | | | | | | | | | | | | | | | | Rusty, commit 3ca4f5ca73057a617f9444a91022d7127041970a virtio: add virtio IDs file moved all device IDs into a single file. While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.

* 9p: disallow RDMA if RDMA CM isn't availableRoland Dreier2009-01-151-1/+1
| | | | | | | | | | | | | | | If INET=y and INFINIBAND=y, but IPV6=m then INFINIBAND_ADDR_TRANS is set to n and the RDMA CM functions rdma_connect() et al are not built. However, the current config dependencies allow NET_9P_RDMA to be selected in this, which leads to a build failure. Fix this by adding a dependency on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.

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>
