Tools: hv: kvp: ensure kvp device fd is closed on exec
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 <vkuznets@redhat.com> Signed-off-by: K. Y.
