Tools: hv: Fix a bug in the key delete code

2018-09-26T06:33:57+00:00

commit 86503bd35dec0ce363e9fdbf5299927422ed3899 upstream. Fix a bug in the key delete code - the num_records range from 0 to num_records-1. Signed-off-by: K. Y. Srinivasan Reported-by: David Binderman Cc: Reviewed-by: Michael Kelley Signed-off-by: Greg Kroah-Hartman

hv: kvp: Avoid reading past allocated blocks from KVP file

2017-12-16T09:32:26+00:00

commit 297d6b6e56c2977fc504c61bbeeaa21296923f89 upstream. While reading in more than one block (50) of KVP records, the allocation goes per block, but the reads used the total number of allocated records (without resetting the pointer/stream). This causes the records buffer to overrun when the refresh reads more than one block over the previous capacity (e.g. reading more than 100 KVP records whereas the in-memory database was empty before). Fix this by reading the correct number of KVP records from file each time. Signed-off-by: Paul Meyer Signed-off-by: Long Li Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

tools/hv: Use include/uapi with __EXPORTED_HEADERS__

[ Upstream commit 50fe6dd10069e7c062e27f29606f6e91ea979399 ] Use the local uapi headers to keep in sync with "recently" added #define's (e.g. VSS_OP_REGISTER1).

tools: hv: Makefile: Add hv_fcopy_daemon to Makefile

2016-04-12T13:11:13+00:00

[ Upstream commit ca04455fba937eb2d85f437900cd1726166192e6 ] hv_fcopy_daemon is not mentioned in Makefile so it must be built manually. Add hv_fcopy_daemon to Makefile. Signed-off-by: Matej Muzila Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

Tools: hv: fix file overwriting of hv_fcopy_daemon

2014-07-09T21:21:26+00:00

hv_fcopy_daemon fails to overwrite a file if the target file already exits. Add O_TRUNC flag on opening. Signed-off-by: Yue Zhang Signed-off-by: Greg Kroah-Hartman

Tools: hv: Handle the case when the target file exists correctly

2014-04-16T21:10:36+00:00

Return the appropriate error code and handle the case when the target file exists correctly. This fixes a bug. Signed-off-by: K. Y. Srinivasan Cc: [3.14] Signed-off-by: Greg Kroah-Hartman

Drivers: hv: Implement the file copy service

2014-02-18T18:53:48+00:00

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.

Tools: hv: vssdaemon: Ignore VFAT mounts during the Freeze operation

2014-02-15T19:53:39+00:00

If the guest has a FAT file system mounted, skip it during the FREEZE operation. With this change we can support host initiated backup of the guest even when the guest may have FAT file systems mounted. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Adding makefile for tools/hv

2014-02-15T19:52:35+00:00

Currently, there is no makefile for the Hyper-V tools. This patch adds the missing makefile, and adds it to the main tools makefile. Signed-off-by: Bjarke Istrup Pedersen Signed-off-by: Greg Kroah-Hartman

Tools: hv: remove inclusion of linux/types.h

2013-12-09T06:47:12+00:00

With very old libc headers the inclusion of sys/types.h causes conflicts with linux/types.h. Since the latter is not required anyway, remove it from the source files. If any of the headers really needs linux/types.h it has to include it itself. Signed-off-by: Olaf Hering Signed-off-by: Greg Kroah-Hartman
