Nicolas Dichtel d3623099d3 ipsec: add support of limited SA dump ... The goal of this patch is to allow userland to dump only a part of SA by specifying a filter during the dump. The kernel is in charge to filter SA, this avoids to generate useless netlink traffic (it save also some cpu cycles). This is particularly useful when there is a big number of SA set on the system. Note that I removed the union in struct xfrm_state_walk to fix a problem on arm. struct netlink_callback->args is defined as a array of 6 long and the first long is used in xfrm code to flag the cb as initialized. Hence, we must have: sizeof(struct xfrm_state_walk) <= sizeof(long) * 5. With the union, it was false on arm (sizeof(struct xfrm_state_walk) was sizeof(long) * 7), due to the padding. In fact, whatever the arch is, this union seems useless, there will be always padding after it. Removing it will not increase the size of this struct (and reduce it on arm).
