2012-01-04hw/9pfs: Add new proxy filesystem driverM. Mohan Kumar
Add new proxy filesystem driver to add root privilege to qemu process. It needs a helper process to be started by root user. Following command line can be used to utilize proxy filesystem driver -virtfs proxy,id=<id>,mount_tag=<tag>,socket_fd=<socket-fd> Signed-off-by: M.

2012-01-04hw/9pfs: Move opt validation to FsDriver callbackAneesh Kumar K.V
This remove all conditional code from common code path and make opt validation a FSDriver callback. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-12-04hw/9pfs: Improve portability to older systemsAneesh Kumar K.V
handle fs driver require a set of newly added syscalls. Don't Compile handle FS driver if those syscalls are not available. Instead of adding #ifdef for all those syscalls we check for open by handle syscall. If that is available then rest of the syscalls used by the driver should be available.

2011-10-31hw/9pfs: Add synthetic file system support using 9pAneesh Kumar K.V
This patch create a synthetic file system with mount tag v_synth when -virtfs_synth command line option is specified in qemu. The synthetic file system can be mounted in guest using 9p using the below command line mount -t 9p -oversion=9p2000.L,trans=virtio v_synth <mountpint> Synthetic file system enabled different qemu subsystem to register callbacks for read and write events from guest. The subsystem can create directories and files in the synthetic file system as show in ex below qemu_v9fs_synth_mkdir(NULL, 0777, "test2", &node); qemu_v9fs_synth_add_file(node, 0777, "testfile", my_test_read, NULL, NULL); Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-31hw/9pfs: Read-only support for 9p exportM. Mohan Kumar
A new fsdev parameter "readonly" is introduced to control accessing 9p export. "readonly" can be used to specify the access type. By default "rw" access is given to 9p export. Signed-off-by: M. Mohan Kumar <mohan@in.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

2010-06-22virtio-9p: Introduces an option to specify the security model.Venkateswararao Jujjuri (JV)
The new option is: -fsdev fstype,id=myid,path=/share_path/,security_model=[mapped|passthrough] -virtfs fstype,path=/share_path/,security_model=[mapped|passthrough],mnt_tag=tag In the case of mapped security model, files are created with QEMU user credentials and the client-user's credentials are saved in extended attributes. Whereas in the case of passthrough security model, files on the filesystem are directly created with client-user's credentials.

This patch creates a new command line option named -fsdev to hold any file system specific information. The option will currently hold the following attributes: -fsdev fstype id=id,path=path_to_share where fstype: Type of the file system. id: Identifier used to refer to this fsdev path: The path on the host that is identified by this fsdev.
