-+ * The hash value of an address is its last byte.
-+ *
-+ * In real-world ethernet addresses, values of the last byte are
-+ * evenly distributed and there is no need to consider other bytes.
-+ * It would only slow the routines down.
++ * Authors:
++ * Bart De Schuymer <bart.de.schuymer@pandora.be>
+ *
-+ * For MAC address comparison speedup reasons, we introduce a trick.
-+ * MAC address is mapped onto an array of two 32-bit integers.
-+ * This pair of integers is compared with MAC addresses in the
-+ * hash table, which are stored also in form of pairs of integers
-+ * (in `cmp' array). This is quick as it requires only two elementary
-+ * number comparisons in worst case. Further, we take advantage of
-+ * fact that entropy of 3 last bytes of address is larger than entropy
-+ * of 3 first bytes. So first we compare 4 last bytes of addresses and
-+ * if they are the same we compare 2 first.

-+ * The table's mode will be honoured both for sys_sysctl(2) and
-+ * proc-fs access.
++ * April, 2003
+ *
-+ * Leaf nodes in the sysctl tree will be represented by a single file
-+ * under /proc; non-leaf nodes will be represented by directories. A
-+ * null procname disables /proc mirroring at this node.
-+ *
-+ * sysctl(2) can automatically manage read and write requests through
-+ * the sysctl table. The data and maxlen fields of the ctl_table
-+ * struct enable minimal validation of the values being written to be
-+ * performed, and the mode field allows minimal authentication.
-+ *
-+ * More sophisticated management can be enabled by the provision of a
-+ * strategy routine with the table entry. This will be called before
-+ * any automatic read or write of the data is performed.
-+ *
-+ * The strategy routine may return:
-+ * <0: Error occurred (error is passed to user process)
-+ * 0: OK - proceed with automatic read or write.
-+ * >0: OK - read or write has been done by the strategy routine, so
-+ * return immediately.
-+ *
-+ * There must be a proc_handler routine for any terminal nodes
-+ * mirrored under /proc/sys (non-terminals are handled by a built-in
-+ * directory handler). Several default handlers are available to
-+ * cover common cases.

-+/* This requires some explaining. If DNAT has taken place,
-+ * we will need to fix up the destination Ethernet address,
-+ * and this is a tricky process.
-+ *
-+ * There are two cases to consider:
-+ * 1. The packet was DNAT'ed to a device in the same bridge
-+ * port group as it was received on. We can still bridge
-+ * the packet.
-+ * 2. The packet was DNAT'ed to a different device, either
-+ * a non-bridged device or another bridge port group.
-+ * The packet will need to be routed.
-+ *
-+ * The correct way of distinguishing between these two cases is to
-+ * call ip_route_input() and to look at skb->dst->dev, which is
-+ * changed to the destination device if ip_route_input() succeeds.
-+ *
-+ * Let us first consider the case that ip_route_input() succeeds:
-+ *
-+ * If skb->dst->dev equals the logical bridge device the packet
-+ * came in on, we can consider this bridging. We then call
-+ * skb->dst->output() which will make the packet enter br_nf_local_out()
-+ * not much later. In that function it is assured that the iptables
-+ * FORWARD chain is traversed for the packet.
-+ *
-+ * Otherwise, the packet is considered to be routed and we just
-+ * change the destination MAC address so that the packet will
-+ * later be passed up to the IP stack to be routed.
-+ *
-+ * Let us now consider the case that ip_route_input() fails:

++ * netfilter module for userspace bridged Ethernet frames logging daemons
++ *
++ * Authors:
++ * Bart De Schuymer <bdschuym@pandora.be>
++ *
++ * November, 2004
++ *
++ * Based on ipt_ULOG.c, which is
++ * (C) 2000-2002 by Harald Welte <laforge@netfilter.org>
++ *
++ * This module accepts two parameters:
++ *
++ * nlbufsiz:
++ * The parameter specifies how big the buffer for each netlink multicast
++ * group is. e.g. If you say nlbufsiz=8192, up to eight kb of packets will
++ * get accumulated in the kernel until they are sent to userspace. It is
++ * NOT possible to allocate more than 128kB, and it is strongly discouraged,
++ * because atomically allocating 128kB inside the network rx softirq is not
++ * reliable. Please also keep in mind that this buffer size is allocated for
++ * each nlgroup you are using, so the total kernel memory usage increases
++ * by that factor.
++ *
++ * flushtimeout:
++ * Specify, after how many hundredths of a second the queue should be
++ * flushed even if it is not full yet.
+ *
-+ * If (nf_bridge->mask & BRNF_BRIDGED_DNAT) then the packet is bridged
-+ * and we fake the PF_BRIDGE/FORWARD hook. The function br_nf_forward()
-+ * will then fake the PF_INET/FORWARD hook. br_nf_local_out() has priority
-+ * NF_BR_PRI_FIRST, so no relevant PF_BRIDGE/INPUT functions have been nor
-+ * will be executed.
-+ * Otherwise, if nf_bridge->physindev is NULL, the bridge-nf code never touched
-+ * this packet before, and so the packet was locally originated. We fake
-+ * the PF_INET/LOCAL_OUT hook.
-+ * Finally, if nf_bridge->physindev isn't NULL, then the packet was IP routed,
-+ * so we fake the PF_INET/FORWARD hook. ipv4_sabotage_out() makes sure
-+ * even routed packets that didn't arrive on a bridge interface have their
-+ * nf_bridge->physindev set.

-+ * netfilter module for userspace bridged Ethernet frames logging daemons
-+ *
-+ * Authors:

-+ *
-+ * November, 2004
-+ *
-+ * Based on ipt_ULOG.c, which is
-+ * (C) 2000-2002 by Harald Welte <laforge@netfilter.org>
-+ *
-+ * This module accepts two parameters:
-+ *
-+ * nlbufsiz:
-+ * The parameter specifies how big the buffer for each netlink multicast
-+ * group is. e.g. If you say nlbufsiz=8192, up to eight kb of packets will
-+ * get accumulated in the kernel until they are sent to userspace. It is
-+ * NOT possible to allocate more than 128kB, and it is strongly discouraged,
-+ * because atomically allocating 128kB inside the network rx softirq is not
-+ * reliable. Please also keep in mind that this buffer size is allocated for
-+ * each nlgroup you are using, so the total kernel memory usage increases
-+ * by that factor.
-+ *
-+ * flushtimeout:
-+ * Specify, after how many hundredths of a second the queue should be
-+ * flushed even if it is not full yet.

++/* Grzegorz Borowiak <grzes@gnu.univ.gda.pl> 2003
++ *
++ * Write-once-read-many hash table, used for checking if a given
++ * MAC address belongs to a set or not and possibly for checking
++ * if it is related with a given IPv4 address.
++ *
++ * The hash value of an address is its last byte.
++ *
++ * In real-world ethernet addresses, values of the last byte are
++ * evenly distributed and there is no need to consider other bytes.
++ * It would only slow the routines down.
++ *
++ * For MAC address comparison speedup reasons, we introduce a trick.
++ * MAC address is mapped onto an array of two 32-bit integers.
++ * This pair of integers is compared with MAC addresses in the
++ * hash table, which are stored also in form of pairs of integers
++ * (in `cmp' array). This is quick as it requires only two elementary
++ * number comparisons in worst case. Further, we take advantage of
++ * fact that entropy of 3 last bytes of address is larger than entropy
++ * of 3 first bytes. So first we compare 4 last bytes of addresses and
++ * if they are the same we compare 2 first.
++ *
++ * Yes, it is a memory overhead, but in 2003 AD, who cares?

++/* This requires some explaining. If DNAT has taken place,

++ *
++ * There are two cases to consider:
++ * 1. The packet was DNAT'ed to a device in the same bridge
++ * port group as it was received on. We can still bridge
++ * the packet.
++ * 2. The packet was DNAT'ed to a different device, either
++ * a non-bridged device or another bridge port group.
++ * The packet will need to be routed.
++ *
++ * The correct way of distinguishing between these two cases is to
++ * call ip_route_input() and to look at skb->dst->dev, which is
++ * changed to the destination device if ip_route_input() succeeds.
++ *
++ * Let us first consider the case that ip_route_input() succeeds:
++ *
++ * If skb->dst->dev equals the logical bridge device the packet
++ * came in on, we can consider this bridging. We then call
++ * skb->dst->output() which will make the packet enter br_nf_local_out()
++ * not much later. In that function it is assured that the iptables
++ * FORWARD chain is traversed for the packet.
++ *
++ * Otherwise, the packet is considered to be routed and we just
++ * change the destination MAC address so that the packet will
++ * later be passed up to the IP stack to be routed.
++ *
++ * Let us now consider the case that ip_route_input() fails:
++ *
++ * After a "echo '0' > /proc/sys/net/ipv4/ip_forward" ip_route_input()
++ * will fail, while __ip_route_output_key() will return success. The source
++ * address for __ip_route_output_key() is set to zero, so __ip_route_output_key
++ * thinks we're handling a locally generated packet and won't care
++ * if IP forwarding is allowed. We send a warning message to the users's
++ * log telling her to put IP forwarding on.
++ *
++ * ip_route_input() will also fail if there is no route available.
++ * In that case we just drop the packet.
