9p: fix readdir corner cases

2009-11-02T14:43:45Z

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 Signed-off-by: Eric Van Hensbergen

9p: Add fscache support to 9p

2009-09-23T18:03:46Z

This patch adds a persistent, read-only caching facility for 9p clients using the FS-Cache caching backend. When the fscache facility is enabled, each inode is associated with a corresponding vcookie which is an index into the FS-Cache indexing tree. The FS-Cache indexing tree is indexed at 3 levels: - session object associated with each mount. - inode/vcookie - actual data (pages) A cache tag is chosen randomly for each session. These tags can be read off /sys/fs/9p/caches and can be passed as a mount-time parameter to re-attach to the specified caching session.

net/9p: handle correctly interrupted 9P requests

2009-04-05T21:54:53Z

Currently the 9p code crashes when a operation is interrupted, i.e. for example when the user presses ^C while reading from a file. This patch fixes the code that is responsible for interruption and flushing of 9P operations. Signed-off-by: Latchesar Ionkov

9p: fix sparse warnings

2008-10-22T23:54:47Z

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

9p: rdma: RDMA Transport Support for 9P

2008-10-22T23:47:39Z

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 Signed-off-by: Latchesar Ionkov

9p: fix debug build error

2008-10-22T23:47:40Z

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

9p: Improve debug support

2008-10-17T21:20:07Z

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

9p: eliminate depricated conv functions

2008-10-17T16:06:57Z

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

9p: rework client code to use new protocol support functions

2008-10-17T16:04:45Z

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

9p: remove unnecessary tag field from p9_req_t structure

2008-10-17T16:04:45Z

This removes the vestigial tag field from the p9_req_t structure. Signed-off-by: Eric Van Hensbergen
