net/9p: fix client code to fail more gracefully on protocol error

2011-11-07T20:31:59+00:00

commit b85f7d92d7bd7e3298159e8b1eed8cb8cbbb0348 upstream. There was a BUG_ON to protect against a bad id which could be dealt with more gracefully. Reported-by: Natalie Orlin Signed-off-by: Eric Van Hensbergen Signed-off-by: Greg Kroah-Hartman

9p: strlen() doesn't count the terminator

2010-08-10T17:20:39+00:00

commit 5c4bfa17f3ec46becec4b23d12323f7605ebd696 upstream. This is an off by one bug because strlen() doesn't count the NULL terminator. We strcpy() addr into a fixed length array of size UNIX_PATH_MAX later on. The addr variable is the name of the device being mounted. Signed-off-by: Dan Carpenter Signed-off-by: David S.

9p: fix readdir corner cases

2009-11-02T14:43:45+00:00

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

virtio: let header files include virtio_ids.h

2009-10-22T06:09:28+00:00

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 " 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.

virtio: add virtio IDs file

2009-09-23T12:56:32+00:00

Virtio IDs are spread all over the tree which makes assigning new IDs bothersome. Putting them together should make the process less error-prone. Signed-off-by: Fernando Luis Vazquez Cao Signed-off-by: Rusty Russell

virtio: get rid of redundant VIRTIO_ID_9P definition

2009-09-23T12:56:32+00:00

VIRTIO_ID_9P is already defined in include/linux/virtio_9p.h so use that definition instead. Signed-off-by: Fernando Luis Vazquez Cao Signed-off-by: Rusty Russell Cc: Eric Van Hensbergen

virtio: make add_buf return capacity remaining

2009-09-23T12:56:31+00:00

This API change means that virtio_net can tell how much capacity remains for buffers. It's necessarily fuzzy, since VIRTIO_RING_F_INDIRECT_DESC means we can fit any number of descriptors in one, *if* we can kmalloc. Signed-off-by: Rusty Russell Cc: Dinesh Subhraveti

net/9p: insulate the client against an invalid error code sent by a 9p server

2009-08-17T21:39:54+00:00

A looney tunes server sending an invalid error code (which is !IS_ERR_VALUE) can result in a client oops. So fix it by adding a check and converting unknown or invalid error codes to -ESERVERFAULT. Signed-off-by: Abhishek Kulkarni Signed-off-by: Eric Van Hensbergen
