tools: hv: skip iso9660 mounts in hv_vss_daemon

2013-04-24T16:02:35Z

fsreeze does not work for iso9660 filesystems. A ENOSUPP may be caught in the freeze case, but the subsequent thaw call would fail and leads to a false error. Signed-off-by: Olaf Hering Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools: hv: use FIFREEZE/FITHAW in hv_vss_daemon

2013-04-24T16:02:35Z

As suggested by Paolo Bonzini, use ioctl instead of calling fsfreeze. Signed-off-by: Olaf Hering Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools: hv: fix checks for origin of netlink message in hv_vss_daemon

2013-04-24T16:02:35Z

Similar to what commit 95a69adab9acfc3981c504737a2b6578e4d846ef ("tools: hv: Netlink source address validation allows DoS") does in hv_kvp_daemon, improve checks for origin of netlink connector message. Signed-off-by: Olaf Hering Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Tools: hv: fix warnings in hv_vss_daemon

Drivers: hv: Add a new driver to support host initiated backup

2013-03-15T19:12:36Z

This driver supports host initiated backup of the guest. On Windows guests, the host can generate application consistent backups using the Windows VSS framework. On Linux, we ensure that the backup will be file system consistent. This driver allows the host to initiate a "Freeze" operation on all the mounted file systems in the guest. Once the mounted file systems in the guest are frozen, the host snapshots the guest's file systems. Once this is done, the guest's file systems are "thawed". This driver has a user-level component (daemon) that invokes the appropriate operation on all the mounted file systems in response to the requests from the host. The duration for which the guest is frozen is very short - a few seconds. During this interval, the diff disk is comitted. In this version of the patch I have addressed the feedback from Olaf Herring. Also, some of the connector related issues have been fixed. Signed-off-by: K. Y.

tools: hv: daemon should check type of received Netlink msg

2013-03-15T18:23:16Z

HyperV KVP daemon should check nlmsg_type in received netlink message header. If message type is NLMSG_DONE daemon can proceed with processing otherwise it should wait for next message. Signed-off-by: Tomas Hozza Acked-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools: hv: daemon setsockopt should use options macros

2013-03-15T18:23:16Z

HyperV daemon should use macros for option values when calling setsockopt. Using specific numeric values instead of macros is confusing. Signed-off-by: Tomas Hozza Acked-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman
