| | | | | | | | | | | | | * if we fail in p9_conn_create(), we shouldn't leak references to struct file. Logics in ->close() doesn't help - ->trans is already gone by the time it's called. * sock_create_kern() can fail. * use of sock_map_fd() is all fscked up; I'd fixed most of that, but the rest will have to wait for a bit more work in net/socket.c (we still are violating the basic rule of working with descriptor table: "once the reference is installed there, don't rely on finding it there again").

* 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.

* 9p: fix sparse warningsEric Van Hensbergen2008-10-222-12/+13
| | | | | | | | | Several sparse warnings were introduced by patches accepted during the merge window which weren't caught. This patch fixes those warnings. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: rdma: RDMA Transport Support for 9PTom Tucker2008-10-223-0/+722
| | | | | | | | | | This patch implements the RDMA transport provider for 9P. It allows mounts to be performed over iWARP and IB capable network interfaces. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Latchesar Ionkov <lionkov@lanl.gov>
* 9p: fix debug build errorEric Van Hensbergen2008-10-222-3/+10
| | | | | | | | | | Fixes build problem with 9p when building with debug disabled. Also contains some fixes for warnings which pop up when CONFIG_NET_9P_DEBUG is disabled. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 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. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 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
| | | | | | | | | | | This removes the vestigial tag field from the p9_req_t structure. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 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.
