Since the remaining bits are not filled in struct bpf_tunnel_key
resp. struct bpf_xfrm_state and originate from uninitialized stack
space, we should make sure to clear them before handing control
back to the program.
Also add a padding element to struct bpf_xfrm_state for future use
similar as we have in struct bpf_tunnel_key and clear it as well.
struct bpf_xfrm_state {
__u32 reqid; /* 0 4 */
__u32 spi; /* 4 4 */
__u16 family; /* 8 2 */
/* XXX 2 bytes hole, try to pack */
union {
__u32 remote_ipv4; /* 4 */
__u32 remote_ipv6[4]; /* 16 */
}; /* 12 16 */
/* size: 28, cachelines: 1, members: 4 */
/* sum members: 26, holes: 1, sum holes: 2 */
/* last cacheline: 28 bytes */
};
