* Drivers: hv: kvp: Copy the address family informationK. Y. Srinivasan2012-09-05
| | | | | | | | | | | | This is part of the IP injection protocol in that the host expects this field to reflect what addresses (address families) are currently bound to the interface. The KVP daemon is currently collecting this information and sending it to the kernel component. I had overlooked copying this and sending it back to the host. This patch addresses this issue.

* Drivers: hv: util: Properly handle version negotiations.K. Y. Srinivasan2012-05-14
| | | | | | | | | | | The current version negotiation code is not "future proof". Fix this by allowing each service the flexibility to either specify the highest version it can support or it can support the highest version number the host is offering. Signed-off-by: K. Y.

* Drivers: hv: Support the newly introduced KVP messages in the driverK. Y. Srinivasan2012-03-16
| | | | | | | | | | | | Support the newly defined KVP message types. It turns out that the host pushes a set of standard key value pairs as soon as the guest opens the KVP channel. Since we cannot handle these tuples until the user level daemon loads up, defer reading the KVP channel until the user level daemon is launched. Signed-off-by: K. Y.

* NLS: improve UTF8 -> UTF16 string conversion routineAlan Stern2011-11-18
| | | | | | | | | | | | | | | | | | | | The utf8s_to_utf16s conversion routine needs to be improved. Unlike its utf16s_to_utf8s sibling, it doesn't accept arguments specifying the maximum length of the output buffer or the endianness of its 16-bit output. This patch (as1501) adds the two missing arguments, and adjusts the only two places in the kernel where the function is called. A follow-on patch will add a third caller that does utilize the new capabilities. The two conversion routines are still annoyingly inconsistent in the way they handle invalid byte combinations. But that's a subject for a different patch. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> CC: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Staging: hv: move hyperv code out of staging directoryGreg Kroah-Hartman2011-10-11
After many years wandering the desert, it is finally time for the Microsoft HyperV code to move out of the staging directory. Or at least the core hyperv bus code, and the utility driver, the rest still have some review to get through by the various subsystem maintainers.
