tools: hv: Netlink source address validation allows DoS
The source code without this patch caused hypervkvpd to exit when it processed a spoofed Netlink packet which has been sent from an untrusted local user. Now Netlink messages with a non-zero nl_pid source address are ignored and a warning is printed into the syslog. Signed-off-by: Tomas Hozza <thozza@redhat.com> Acked-by: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
