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

2017-12-16T09:33:48+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: kvp: ensure kvp device fd is closed on exec

2017-04-27T07:09:33+00:00

commit 26840437cbd6d3625ea6ab34e17cd34bb810c861 upstream. KVP daemon does fork()/exec() (with popen()) so we need to close our fds to avoid sharing them with child processes. The immediate implication of not doing so I see is SELinux complaining about 'ip' trying to access '/dev/vmbus/hv_kvp'. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y.

tools: hv: report ENOSPC errors in hv_fcopy_daemon

2016-09-15T06:27:40+00:00

[ Upstream commit b4ed5d1682c6613988c2eb1de55df5ac9988afcc ] Currently some "Unspecified error 0x80004005" is reported on the Windows side if something fails. Handle the ENOSPC case and return ERROR_DISK_FULL, which allows at least Copy-VMFile to report a meaning full error. Signed-off-by: Olaf Hering Signed-off-by: K. Y.

tools/hv: Use include/uapi with __EXPORTED_HEADERS__

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

By default lsvmbus lists all the devices in the VMBus. With -v or -vv, more information is printed, including the VMBus Rel_ID, class ID, device ID and which channel is bound to which virtual processor, etc. Signed-off-by: Dexuan Cui Signed-off-by: K. Y.
