2011-12-04hw/9pfs: use migration blockers to prevent live migration when virtfs export ↵Aneesh Kumar K.V
path is mounted Now when you try to migrate with VirtFS export path mounted, you get a proper QMP error: (qemu) migrate tcp:localhost:4444 Migration is disabled when VirtFS export path '/tmp/' is mounted in the guest using mount_tag 'v_tmp' (qemu) Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

Use file system driver specific lstat instead of generic lstat. 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: Add st_gen support in getattr replyHarsh Prateek Bora
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>
2011-10-15hw/9pfs: Ensure an error is reported to user if 9pfs mount tag is too longDaniel P. Berrange
If the 9pfs mount tag is longer than MAX_TAG_LEN bytes, rather than silently truncating the tag which will likely break the guest OS, report an immediate error and exit QEMU * hw/9pfs/virtio-9p-device.c: Report error & exit if mount tag is too long Signed-off-by: Daniel P.

2011-06-01virtio-9p: Use relative includes for files in hwStefan Weil
Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files without fixing the include paths. It used a modified CFLAGS to add hw to the include search path, but this breaks builds where the user wants to set special CFLAGS. Long include paths also increase compilation time. Therefore this patch removes the special CFLAGS for virtio and fixes the include statements by using relative include paths. v2: Remove special CFLAGS. v3: Update needed for latest QEMU.
