Adds support for specifying a range of queues instead of a single queue
id.
Flows will be distributed across the given range.
This is useful for multicore systems: Instead of having a single
application read packets from a queue, start multiple
instances on queues x, x+1, .. x+n. Each instance can process
flows independently.
Packets for the same connection are put into the same queue.
Nice work, applied. I've made two minor cosmetic changes:
+#if defined(CONFIG_IP6_NF_IPTABLES) || defined(CONFIG_IP6_NF_IPTABLES_MODULE)
+static u32 hash_v6(const struct sk_buff *skb)
+{
+ const struct ipv6hdr *ip6h = ipv6_hdr(skb);
+ u32 addr[4];
+
+ addr[0] = ip6h->saddr.s6_addr32[0] ^ ip6h->daddr.s6_addr32[0];
+ addr[1] = ip6h->saddr.s6_addr32[1] ^ ip6h->daddr.s6_addr32[1];
+ addr[2] = ip6h->saddr.s6_addr32[2] ^ ip6h->daddr.s6_addr32[2];
+ addr[3] = ip6h->saddr.s6_addr32[3] ^ ip6h->daddr.s6_addr32[3];
+
+ return jhash2(addr, 4, jhash_initval);
I changed 4 to ARRAY_SIZE(addr)
+static bool nfqueue_tg_v1_check(const struct xt_tgchk_param *par)
+{
+ const struct xt_NFQ_info_v1 *info = par->targinfo;
+ u32 maxid;
+
+ if (info->queues_total == 0) {
+ printk(KERN_ERR "NFQUEUE: number of total queues is 0\n");
+ return false;
+ }
+ maxid = info->queues_total - 1 + info->queuenum;
+ if (maxid > 0xffff) {
+ printk(KERN_ERR "NFQUEUE: number of queues (%u) out of range (got %u)\n",
+ info->queues_total, maxid);
+ return false;
+ }
+ return true;
+}
and these printks to use pr_err to bring the line size down.
