This patch set expands the KVP (Key Value Pair) functionality to implement the mechanism to GET/SET IP addresses in the guest. This functionality is used in Windows Server 2012 to implement VM replication functionality. The way IP configuration information is managed is distro specific. Based on the feedback I have gotten from Olaf, Greg, Steve, Ben and Mairus, I have chosen to seperate distro specific code from this patch-set. Most of the GET operation can be implemented in a way that is completely distro independent and I have implemented that as such and is included in this patch-set. Some of the attributes that can only be fetched in a distro dependent way as well the mechanism for configuring an interface (the SET operation) that is clearly distro specific is to be implemented via external scripts that will be invoked via the KVP code. We define here the interface to these scripts. Adding support for IP injection resulted in some changes to the protocol between the user level daemon and the kernel driver. These changes have been implemented in way that would retain compatibility with older daemons. I would like to thank Olaf and Greg for pointing out the compatibility issue. This version of the patch set addresses all of the comments that I have received to date from Olaf, Ben and others. Specifically, I have cleanedup all of the string manipulation code. Furthermore, I have also simplified the format of the interface configuration file that is generated by the KVP daemon and gotten rid of some constant strings that may not be relevant on all distros. I would like to thank Olaf and Ben for their detailed review. Following are the changes from V2 of this patch set: 1. Addressed the indentation issue Greg noted in the patch: 0001-Drivers-hv-kvp-Support-the-new-IP-injection-messages.patch 2. Cleaned up the Reviewed-byi line based on input from Ben and Greg. 3. Since Ben had an identical patch for properly closing the open streams, I have not included that patch in this series. 4. Greg applied the first 3 patches of the V2 patch set. This version has the remaining patches. K. Y.
