Harsh Prateek Bora e06a765efb hw/9pfs: Add st_gen support in getattr reply
This patch use file system specific ioctl for getting i_generation
value. Not all file system support the ioctl. So we add an export
specific extended operation and assign right callback for the
file system that support i_generation ioctl

["M. Mohan Kumar" <mohan@in.ibm.com> we can do ioctl only for
regular files and directories on the server]

Venkateswararao Jujjuri (JV) faa44e3d3e [virtio-9p] Make rpath thread safe
Current rpath inline function is heavily used in all system calls.
This function has a static buffer making it a non-thread safe function.
This patch introduces new thread-safe routine and makes use of it.

Gerd Hoffmann 526c523781 Use machine_init() to register virtfs config options. 2010-09-21 18:35:30 +02:00
Venkateswararao Jujjuri (JV) 9ce56db6f0 virtio-9p: Introduces an option to specify the security model.
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.
