While looking at UDP port randomization, I noticed it was litle bit pessimistic, not looking at type of sockets (IPV6/IPV4) and not looking at bound addresses if any.

2008-10-09inet: Make tunnel RX/TX byte counters more consistentHerbert Xu
This patch makes the RX/TX byte counters for IPIP, GRE and SIT more consistent. Previously we included the external IP headers on the way out but not when the packet is inbound. The new scheme is to count payload only in both directions. For IPIP and SIT this simply means the exclusion of the external IP header. For GRE this means that we exclude the GRE header as well.

2008-10-09gre: Add Transparent Ethernet BridgingHerbert Xu
This patch adds support for Ethernet over GRE encapsulation. This is exposed to user-space with a new link type of "gretap" instead of "gre". It will create an ARPHRD_ETHER device in lieu of the usual ARPHRD_IPGRE. Note that to preserver backwards compatibility all Transparent Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel if its key matches and there is no ARPHRD_ETHER device whose key matches more closely.

2008-10-09gre: Add netlink interfaceHerbert Xu
This patch adds a netlink interface that will eventually displace the existing ioctl interface. It utilises the elegant rtnl_link_ops mechanism. This also means that user-space no longer needs to rely on the tunnel interface being of type GRE to identify GRE tunnels. The identification can now occur using rtnl_link_ops.

2008-10-09gre: Move MTU setting out of ipgre_tunnel_bind_devHerbert Xu
This patch moves the dev->mtu setting out of ipgre_tunnel_bind_dev. This is in prepartion of using rtnl_link where we'll need to make the MTU setting conditional on whether the user has supplied an MTU. This also requires the move of the ipgre_tunnel_bind_dev call out of the dev->init function so that we can access the user parameters later. This patch also adds a check to prevent setting the MTU below the minimum of 68. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-09gre: Use needed_headroomHerbert Xu
Now that we have dev->needed_headroom, we can use it instead of having a bogus dev->hard_header_len. This also allows us to include dev->hard_header_len in the MTU computation so that when we do have a meaningful hard_harder_len in future it is included automatically in figuring out the MTU. Incidentally, this fixes a bug where we ignored the needed_headroom field of the underlying device in calculating our own hard_header_len.

2008-10-08dsa: add support for the Marvell 88E6131 switch chipLennert Buytenhek
Add support for the Marvell 88E6131 switch chip. This chip only supports the original (ethertype-less) DSA tagging format. On the 88E6131, there is a PHY Polling Unit (PPU) which has exclusive access to each of the PHYs's MII management registers. If we want to talk to the PHYs from software, we have to disable the PPU and wait for it to complete its current transaction before we can do so, and we need to re-enable the PPU afterwards to make sure that the switch will notice changes in link state and speed on the individual ports as they occur. Since disabling the PPU is rather slow, and since MII management accesses are typically done in bursts, this patch keeps the PPU disabled for 10ms after a software access completes. This makes handling the PPU slightly more complex, but speeds up something like running ethtool on one of the switch slave interfaces from ~300ms to ~30ms on typical hardware.

2008-10-08dsa: add support for original DSA tagging formatLennert Buytenhek
Most of the DSA switches currently in the field do not support the Ethertype DSA tagging format that one of the previous patches added support for, but only the original DSA tagging format. The original DSA tagging format carries the same information as the Ethertype DSA tagging format, but with the difference that it does not have an ethertype field. In other words, when receiving a packet that is tagged with an original DSA tag, there is no way of telling in eth_type_trans() that this packet is in fact a DSA-tagged packet. This patch adds a hook into eth_type_trans() which is only compiled in if support for a switch chip that doesn't support Ethertype DSA is selected, and which checks whether there is a DSA switch driver instance attached to this network device which uses the old tag format. If so, it sets the protocol field to ETH_P_DSA without looking at the packet, so that the packet ends up in the right place.
