2011-10-15hw/9pfs: Add open flag mappingM. Mohan Kumar
Some of the flags are OS/arch dependent we need to use 9P defined value on wire, Based on the original patch from Venkateswararao Jujjuri <jvrao@linux.vnet.ibm.com> Signed-off-by: M. Mohan Kumar <mohan@in.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-15virtio-9p: Use 9P specific Lock constantsM. Mohan Kumar
Use 9P specific lock constants instead of arch specific lock constants. Signed-off-by: M. Mohan Kumar <mohan@in.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-12hw/9pfs: Add new virtfs option writeout=immediate skip host page cacheAneesh Kumar K.V
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>

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.V
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: Move fid pathname tracking to seperate data type.Aneesh Kumar K.V
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>
2011-09-22hw/9pfs: Use read-write lock for protecting fid path.Aneesh Kumar K.V
On rename we take the write lock and this ensure path doesn't change as we operate on them. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-22hw/9pfs: Make v9fs_string* functions non-staticAneesh Kumar K.V
We will use them later in other files Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-09hw/9pfs: add 9P2000.L unlinkat operationAneesh Kumar K.V
unlinkat - Remove a directory entry size[4] Tunlinkat tag[2] dirfid[4] name[s] flag[4] size[4] Runlinkat tag[2] older Tremove have the below request format size[4] Tremove tag[2] fid[4] The remove message is used to remove a directory entry either file or directory The remove opreation is actually a directory opertation and should ideally have dirfid, if not we cannot represent the fid on server with anything other than name. We will have to derive the directory name from fid in the Tremove request. NOTE: The operation doesn't clunk the unlink fid. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-09hw/9pfs: add 9P2000.L renameat operationAneesh Kumar K.V

The rename opreation is actually a directory opertation and should ideally have olddirfid, if not we cannot represent the fid on server with anything other than name. We will have to derive the old directory name from fid in the Trename request. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

2011-09-09hw/9pfs: Initialize rest of qid field to zero.Aneesh Kumar K.V
Since qid is allocated out of stack we need to intialize the field to zero. Otherwise we will send wrong qid value to client. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-09-09hw/9pfs: Update the fidp path before opendirAneesh Kumar K.V
We need to update the fidp path before opendir. Since we don't use the fid returned by mkdir, earlier code should not have much issue. We do a double v9fs_string_copy here. The later patch cleanup the entire function. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
