* netfilter: ctnetlink: remove bogus module dependency between ctnetlink and ↵Pablo Neira Ayuso2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | nf_nat This patch removes the module dependency between ctnetlink and nf_nat by means of an indirect call that is initialized when nf_nat is loaded. Now, nf_conntrack_netlink only requires nf_conntrack and nfnetlink. This patch puts nfnetlink_parse_nat_setup_hook into the nf_conntrack_core to avoid dependencies between ctnetlink, nf_conntrack_ipv4 and nf_conntrack_ipv6. This patch also introduces the function ctnetlink_change_nat that is only invoked from the creation path. Actually, the nat handling cannot be invoked from the update path since this is not allowed. By introducing this function, we remove the useless nat handling in the update path and we avoid deadlock-prone code. This patch also adds the required EAGAIN logic for nfnetlink.

* net: fix dummy 'nf_conntrack_event_cache()'Linus Torvalds2008-10-11
| | | | | | | | | | | | | | | | | The dummy version of 'nf_conntrack_event_cache()' (used when the NF_CONNTRACK_EVENTS config option is not enabled) had not been updated when the calling convention changed. This was introduced by commit a71996fccce4b2086a26036aa3c915365ca36926 ("netfilter: netns nf_conntrack: pass conntrack to nf_conntrack_event_cache() not skb") Tssk.

* inet: Make tunnel RX/TX byte counters more consistentHerbert Xu2008-10-09
| | | | | | | | | | | | | | 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.

* dsa: add support for Trailer tagging formatLennert Buytenhek2008-10-08
| | | | | | | | | | | | This adds support for the Trailer switch tagging format. This is another tagging that doesn't explicitly mark tagged packets with a distinct ethertype, so that we need to add a similar hack in the receive path as for the Original DSA tagging format.

* dsa: add support for original DSA tagging formatLennert Buytenhek2008-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: Distributed Switch Architecture protocol supportLennert Buytenhek2008-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

* sctp: shrink sctp_tsnmap some more by removing gabs arrayVlad Yasevich2008-10-08
| | | | | | | | | | | | | The gabs array in the sctp_tsnmap structure is only used in one place, sctp_make_sack(). As such, carrying the array around in the sctp_tsnmap and thus directly in the sctp_association is rather pointless since most of the time it's just taking up space. Now, let sctp_make_sack create and populate it and then throw it away when it's done. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sctp: Rework the tsn map to use generic bitmap.Vlad Yasevich2008-10-08
| | | | | | | | | | | | | | | | | | | The tsn map currently use is 4K large and is stuck inside the sctp_association structure making memory references REALLY expensive. What we really need is at most 4K worth of bits so the biggest map we would have is 512 bytes. Also, the map is only really usefull when we have gaps to store and report. As such, starting with minimal map of say 32 TSNs (bits) should be enough for normal low-loss operations. We can grow the map by some multiple of 32 along with some extra room any time we receive the TSN which would put us outside of the map boundry. As we close gaps, we can shift the map to rebase it on the latest TSN we've seen. This saves 4088 bytes per association just in the map alone along savings from the now unnecessary structure members.

* inet: cleanup of local_port_rangeEric Dumazet2008-10-08
| | | | | | | | | | | | | | | | | | I noticed sysctl_local_port_range[] and its associated seqlock sysctl_local_port_range_lock were on separate cache lines. Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values.
