Revision 7307616245babb12c923151d8ef69af02e46c255 authored by Dan Carpenter on 13 October 2016, 08:06:06 UTC, committed by David S. Miller on 13 October 2016, 16:10:01 UTC
We should clear out the padding and unused struct members so that we don't expose stack information to userspace. Fixes: fdb3accc2c15 ('tipc: add the ability to get UDP options via netlink') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
