net: use NLMSG_DEFAULT_SIZE in nlmsg_new() allocations
nlmsg_new() adds the size of the netlink header to the value that has been passed as parameter. If NLMSG_GOODSIZE is selected, we request an allocation of one memory page plus the size of the header. Instead, NLMSG_DEFAULT_SIZE should be used since it already substracts the size of the Netlink header. I have the impression that the similar naming in both constant is error prone when using it with nlmsg_new(). This is already documented in include/net/netlink.h Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
