2012-01-19hw/9pfs: Add new security model mapped-file.Aneesh Kumar K.V1-4/+8
This enable us to do passthrough equivalent security model on NFS directory. NFS server mostly do root squashing and don't support xattr. Hence we cannot use 'passthrough' or 'mapped' security model Also added "mapped-xattr" security to indicate earlier "mapped" security model Older name is still supported. POSIX rules regarding ctime update on chmod are not followed by this security model. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2012-01-04hw/9pfs: Add support to use named socket for proxy FSM. Mohan Kumar1-0/+2
Add option to use named socket for communicating between proxy helper and qemu proxy FS. Access to socket can be given by using command line options -u and -g. Signed-off-by: M. Mohan Kumar <mohan@in.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2012-01-04hw/9pfs: Move opt validation to FsDriver callbackAneesh Kumar K.V1-2/+13
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>
2011-12-21hw/9pfs: Use the correct signed type for different variablesAneesh Kumar K.V1-1/+1
Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-12-04hw/9pfs: Use the correct file descriptor in Fsdriver CallbackAneesh Kumar K.V1-2/+2
Fsdriver callback that operate on file descriptor need to differentiate between directory fd and file fd. Based on the original patch from Sassan Panahinejad <sassan@sassan.me.uk> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-31hw/9pfs: Abstract open state of fid to V9fsFidOpenStateAneesh Kumar K.V1-13/+19
To implement synthetic file system in Qemu we may not really require file descriptor and Dir *. Make generic code use V9fsFidOpenState instead. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-31hw/9pfs: Read-only support for 9p exportM. Mohan Kumar1-1/+3
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>
2011-10-15hw/9pfs: Use export flag for indicating security modelAneesh Kumar K.V1-19/+17
This helps to remove some of the structure members Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-15hw/9pfs: Use export_flag for indicating whether fs driver use path names.Aneesh Kumar K.V1-5/+2
This allows us to remove another member from the struct Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-15hw/9pfs: Add st_gen support in getattr replyHarsh Prateek Bora1-0/+8
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] Signed-off-by: Harsh Prateek Bora <harsh@linux.vnet.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-12hw/9pfs: Add new virtfs option writeout=immediate skip host page cacheAneesh Kumar K.V1-0/+4
writeout=immediate implies the after pwritev we do a sync_file_range. Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Add fs driver specific details to fscontextAneesh Kumar K.V1-0/+6
Add a new context flag PATHNAME_FSCONTEXT and indicate whether the fs driver track fid using path names. Also add a private pointer that help us to track fs driver specific values in there Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Add init callback to fs driverAneesh Kumar K.V1-0/+2
This call back can be used to do fs driver specific initialization. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Move fid pathname tracking to seperate data type.Aneesh Kumar K.V1-18/+28
This enables us to add handles to track fids later. The V9fsPath added is similar to V9fsString except that the size include the NULL byte also. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

2011-06-01[virtio-9p] Make rpath thread safeVenkateswararao Jujjuri (JV)1-7/+0
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. Signed-off-by: Venkateswararao Jujjuri "<jvrao@linux.vnet.ibm.com>
2011-04-27virtio-9p: move 9p files aroundAneesh Kumar K.V1-0/+107
Now that we start adding more files related to 9pfs it make sense to move them to a separate directory Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Venkateswararao Jujjuri <jvrao@linux.vnet.ibm.com>
