Looking at that code I suppose that if I want send/receive "struct pps_netlink_msg" to/from the kernel I have to define: static struct genl_family pps_gnl_family = { .id = GENL_ID_GENERATE, /* don't bother with a hardcoded ID */ .name = "PPS", .hdrsize = 0, /* no private header */ .version = PPS_FAMILY_VER, .maxattr = 1, }; static struct nla_policy pps_genl_policy[1] = { [0] = { .type = NLA_BINARY, .len = sizeof(struct pps_netlink_msg), }, }; static struct genl_ops pps_gnl_ops = { .cmd = 0x1, .policy = pps_genl_policy, .doit = pps_genl_data_ready, }; Then the pps_genl_data_ready() should do: static int pps_genl_data_ready(struct sk_buff *skb, struct genl_info *info) { struct pps_netlink_msg *msg = nla_data(info->attrs[0]); int cmd, source; unsigned long timeout; int ret; if (!msg) return -EINVAL; /* Do the job and put the answer into msg struct itself... */ genlmsg_unicast(skb, info->snd_pid); return 0; } Is that right?
