* netlink: Get rid of obsolete rtnetlink macrosThomas Graf2012-06-272-13/+8
| | | | | | | | | Removes all RTA_GET*() and RTA_PUT*() variations, as well as the the unused rtattr_strcmp(). Get rid of rtm_get_table() by moving it to its only user decnet. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

* ipv4: tcp: dont cache unconfirmed intput dstEric Dumazet2012-06-276-9/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | DDOS synflood attacks hit badly IP route cache. On typical machines, this cache is allowed to hold up to 8 Millions dst entries, 256 bytes for each, for a total of 2GB of memory. rt_garbage_collect() triggers and tries to cleanup things. Eventually route cache is disabled but machine is under fire and might OOM and crash. This patch exploits the new TCP early demux, to set a nocache boolean in case incoming TCP frame is for a not yet ESTABLISHED or TIMEWAIT socket. This 'nocache' boolean is then used in case dst entry is not found in route cache, to create an unhashed dst entry (DST_NOCACHE) SYN-cookie-ACK sent use a similar mechanism (ipv4: tcp: dont cache output dst for syncookies), so after this patch, a machine is able to absorb a DDOS synflood attack without polluting its IP route cache.

* mac802154: add wpan device-class supportalex.bluesman.smirnov@gmail.com2012-06-266-1/+573
| | | | | | | | | | | | | | | | | | | | Every real 802.15.4 transceiver, which works with software MAC layer, can be classified as a wpan device in this stack. So the wpan device implementation provides missing link in datapath between the device drivers and the Linux network queue. According to the IEEE 802.15.4 standard each packet can be one of the following types: - beacon - MAC layer command - ACK - data This patch adds support for the data packet-type only, but this is enough to perform data transmission and receiving over radio.

| | | | | | | | | | | | And account for the fact that, when we are not forwarding, we should bump statistic counters rather than emit an ICMP response.

* net/ipv6/route.c: packets originating on device match loDavid McCullough2012-06-251-0/+2
| | | | | | | | | | | | | | | Fix to allow IPv6 packets originating locally to match rules with the "iff" set to "lo". This allows IPv6 rule matching work the same as it does for IPv4. From the iproute2 man page: iif NAME select the incoming device to match. If the interface is loop‐ back, the rule only matches packets originating from this host. This means that you may create separate routing tables for for‐ warded and local packets and, hence, completely segregate them.
