9p: fix bad error path in conversion routines

2007-08-23T15:25:05Z

When buf_check_overflow() returns != 0 we will hit kfree(ERR_PTR(err)) and it will not be happy about it. Signed-off-by: Mariusz Kozlowski Signed-off-by: Eric Van Hensbergen

9p: fix use after free

9p: Don't use binary sysctl numbers.

2007-07-22T19:43:28Z

The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that supposedly only moved files also introduced a new 9p sysctl interface that did not properly register it's sysctl binary numbers. And since it was only for debugging clearly did not need a binary fast path in any case. So this patch just remove the binary numbers. See Documentation/sysctl/ctl_unnumbered.txt for more details. While I was at it I cleaned up the sysctl initializers a little as well so there is less to read. Cc: Latchesar Ionkov Cc: Eric Van Hensbergen Signed-off-by: Eric W.

9p: fix a race condition bug in umount which caused a segfault

2007-07-14T20:14:19Z

umounting partitions after heavy activity would sometimes trigger a segmentation violation. This fix appears to remove that problem. Fix originally provided by Latchesar Ionkov. Signed-off-by: Eric Van Hensbergen

net/9p: set error to EREMOTEIO if trans->write returns zero

2007-07-14T20:14:01Z

If trans->write returns 0, p9_write_work goes through the error path, but sets the error code to zero. This patch sets the error code to EREMOTEIO if trans->write returns zero value. Signed-off-by: Latchesar Ionkov

net/9p: change net/9p module name to 9pnet

2007-07-14T20:13:50Z

Change module name of net/9p module from 9p.ko to 9pnet.ko. fs/9p module already uses 9p.ko name. Signed-off-by: Latchesar Ionkov

9p: Reorganization of 9p file system code

2007-07-14T20:13:40Z

This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p. It moves the transport, packet marshalling and connection layers to net/9p leaving only the VFS related files in fs/9p. This work is being done in preparation for in-kernel 9p servers as well as alternate 9p clients (other than VFS). Signed-off-by: Latchesar Ionkov Signed-off-by: Eric Van Hensbergen
