NLS: improve UTF8 -> UTF16 string conversion routine

2013-03-20T15:03:41Z

commit 0720a06a7518c9d0c0125bd5d1f3b6264c55c3dd upstream. 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 CC: Clemens Ladisch Signed-off-by: Greg Kroah-Hartman Signed-off-by: Ben Hutchings

Drivers: hv: Cleanup error handling in vmbus_open()

Drivers:hv: Fix a bug in vmbus_driver_unregister()

2012-01-12T19:29:33Z

commit 8f257a142fc3868d69de3f996b95d7bdbc509560 upstream. The function vmbus_exists() was introduced recently to deal with cases where the vmbus driver failed to initialize and yet other Hyper-V drivers attempted to register with the vmbus bus driver. This patch introduced a bug where vmbus_driver_unregister() would fail to unregister the driver. This patch fixes the problem. Signed-off-by: K. Y.

drivers: hv: Don't OOPS when you cannot init vmbus

2012-01-12T19:29:32Z

commit cf6a2eacbcb2593b5b91d0817915c4f0464bb534 upstream. The hv vmbus driver was causing an OOPS since it was trying to register drivers on top of the bus even if initialization of the bus has failed for some reason (such as the odd chance someone would run a hv enabled kernel in a non-hv environment).

hv: remove struct hv_device_info from hyperv.h

2011-10-11T15:51:22Z

This is only used/needed by the vmbus core code, so move it out of the hyperv.h file and into the .c file that uses it. Signed-off-by: Greg Kroah-Hartman

hv: remove free_channel() from hyperv.h

2011-10-11T15:51:22Z

This function is only used in the file it is declared in (channel_mgmt.c) so make it static and remove it from the hyperv.h file. Cc: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Staging: hv: remove vmbus_loglevel as it is not used at all anymore

2011-10-11T15:51:21Z

As there is no user of this variable, it's time to delete it. For dynamic debugging of the hyperv code, use the standard dynamic debug kernel interface. Cc: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Staging: hv: remove last user of DPRINT() macro

2011-10-11T15:51:21Z

This also removed the unused function hv_dump_ring_info(). Cc: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

hv: rename prep_negotiate_resp() to vmbus_prep_negotiate_resp()

2011-10-11T14:49:19Z

It's a global symbol, so properly prefix it and use the proper EXPORT value as well. Cc: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Staging: hv: remove unneeded asm include file in hyperv.h

2011-10-11T14:49:19Z

No one outside of the hyperv core needs to include the asm/hyperv.h file, so don't put it in the "global" include/linux/hyperv.h file. Cc: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman
