Drivers: hv: util: On device remove, close the channel after de-initializing the service

2015-03-02T03:31:02Z

When the offer is rescinded, vmbus_close() can free up the channel; deinitialize the service before closing the channel. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

hv: hv_util: move vmbus_open() to a later place

2015-03-02T03:30:07Z

Before the line vmbus_open() returns, srv->util_cb can be already running and the variables, like util_fw_version, are needed by the srv->util_cb. So we have to make sure the variables are initialized before the vmbus_open(). CC: "K. Y. Srinivasan" Reviewed-by: Vitaly Kuznetsov Reviewed-by: Jason Wang Signed-off-by: Dexuan Cui Signed-off-by: K.

Drivers: hv: util: Fix a bug in the KVP code

2014-07-09T21:34:35Z

Add code to poll the channel since we process only one message at a time and the host may not interrupt us. Also increase the receive buffer size since some KVP messages are close to 8K bytes in size. Signed-off-by: K. Y. Srinivasan Cc: Signed-off-by: Greg Kroah-Hartman

Drivers: hv: Implement the file copy service

2014-02-18T18:53:48Z

Implement the file copy service for Linux guests on Hyper-V. This permits the host to copy a file (over VMBUS) into the guest. This facility is part of "guest integration services" supported on the Windows platform. Here is a link that provides additional details on this functionality: http://technet.microsoft.com/en-us/library/dn464282.aspx In V1 version of the patch I have addressed comments from Olaf Hering and Dan Carpenter In V2 version of this patch I did some minor cleanup (making some globals static). In V4 version of the patch I have addressed all of Olaf's most recent set of comments/concerns. In V5 version of the patch I had addressed Greg's most recent comments. I would like to thank Greg for suggesting that I use misc device; it has significantly simplified the code. In V6 version of the patch I have cleaned up error message based on Olaf's comments. I have also rebased the patch based on the current tip. In this version of the patch, I have addressed the latest comments from Greg. Signed-off-by: K. Y.

Drivers: hv: util: Correctly support ws2008R2 and earlier

2013-09-26T21:20:21Z

The current code does not correctly negotiate the version numbers for the util driver when hosted on earlier hosts. The version numbers presented by this driver were not compatible with the version numbers supported by Windows Server 2008. Fix this problem. I would like to thank Olaf Hering (ohering@suse.com) for identifying the problem. Reported-by: Olaf Hering Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

hv: Change variable type to bool

2013-09-26T15:53:23Z

The variable execute_shutdown is only assigned the values true and false. Change its type to bool. The simplified semantic patch that find this problem is as follows (http://coccinelle.lip6.fr/): @exists@ type T; identifier b; @@ - T + bool b = ...; ... when any b = \(true\|false\) Signed-off-by: Peter Senna Tschudin Signed-off-by: Greg Kroah-Hartman

Drivers: hv: remove HV_DRV_VERSION

2013-08-02T03:34:30Z

Remove HV_DRV_VERSION, it has no meaning for upstream drivers. Initially it was supposed to show the "Linux Integration Services" version, now it is not in sync anymore with the out-of-tree drivers available from the MSFT website. The only place where a version string is still required is the KVP command "IntegrationServicesVersion" which is handled by tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass the current string to the daemon during KVP userland registration. Signed-off-by: Olaf Hering Acked-by: K. Y.

Drivers: hv: util: Fix a bug in version negotiation code for util services

2013-07-26T23:40:41Z

The current code picked the highest version advertised by the host. WS2012 R2 has implemented a protocol version for KVP that is not compatible with prior protocol versions of KVP. Fix the bug in the current code by explicitly specifying the protocol version that the guest can support. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

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.
