In the mapped security model, VirtFS server intercepts and maps the file object create and get/set attribute requests. Files on the fileserver will be created with VirtFS servers (QEMU) user credentials and the client-users credentials are stored in extended attributes. On the request to get attributes, server extracts the client-users credentials from extended attributes and sends them to the client.

mapped model changes the owner in the extended attributes. passthrough model does the change through lchown() as the server don't need to follow the link and client will send the actual filesystem object.

This patch adds required infrastructure for the new security model. - A new configure option for attr/xattr. - if CONFIG_VIRTFS will be defined if both CONFIG_LINUX and CONFIG_ATTR defined. - Defines routines related to both security models.

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.
