* [NETFILTER]: nf_nat: kill global 'destroy' operationYasuyuki Kozakai2007-07-102-32/+22
| | | | | | | | | | This kills the global 'destroy' operation which was used by NAT. Instead it uses the extension infrastructure so that multiple extensions can register own operations.

* [NETFILTER]: nf_conntrack: introduce extension infrastructureYasuyuki Kozakai2007-07-103-1/+200
| | | | | | | | | | | | | | | | Old space allocator of conntrack had problems about extensibility. - It required slab cache per combination of extensions. - It expected what extensions would be assigned, but it was impossible to expect that completely, then we allocated bigger memory object than really required. - It needed to search helper twice due to lock issue. Now basic informations of a connection are stored in 'struct nf_conn'. And a storage for extension (helper, NAT) is allocated by kmalloc.

| | | | | | | | | | | | | | The initial rate for STA's using rc80211_simple is set to the last rate in the rate table. For situations for which the signal is weak, the rate may be too high for authentication and association. Although the rc80211_simple module will adjust the speed, the response may not be fast enough for a successful connection. This modification sets the initial rate to the lowest supported value.

* [UDP]: Introduce UDP encapsulation type for L2TPJames Chapman2007-07-101-4/+23
| | | | | | | | | | | | | | | | | | This patch adds a new UDP_ENCAP_L2TPINUDP encapsulation type for UDP sockets. When a UDP socket's encap_type is UDP_ENCAP_L2TPINUDP, the skb is delivered to a function pointed to by the udp_sock's encap_rcv funcptr. If the skb isn't wanted by L2TP, it returns >0, which causes it to be passed through to UDP. Include padding to put the new encap_rcv field on a 4-byte boundary. Previously, the only user of UDP encap sockets was ESP, so when CONFIG_XFRM was not defined, some of the encap code was compiled out. This patch changes that. As a result, udp_encap_rcv() will now do a little more work when CONFIG_XFRM is not defined. Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: dev: secondary unicast address supportPatrick McHardy2007-07-102-52/+129
| | | | | | | | | | | | Add support for configuring secondary unicast addresses on network devices. To support this devices capable of filtering multiple unicast addresses need to change their set_multicast_list function to configure unicast filters as well and assign it to dev->set_rx_mode instead of dev->set_multicast_list. Other devices are put into promiscous mode when secondary unicast addresses are present. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: dev_mcast: switch to generic net_device address listsPatrick McHardy2007-07-101-81/+15

* [NET]: IPV6 checksum offloading in network devicesStephen Hemminger2007-07-106-8/+37
| | | | | | | | | | | | | | | The existing model for checksum offload does not correctly handle devices that can offload IPV4 and IPV6 only. The NETIF_F_HW_CSUM flag implies device can do any arbitrary protocol. This patch: * adds NETIF_F_IPV6_CSUM for those devices * fixes bnx2 and tg3 devices that need it * add NETIF_F_IPV6_CSUM to ipv6 output (incl GSO) * fixes assumptions about NETIF_F_ALL_CSUM in nat * adjusts bridge union of checksumming computation Signed-off-by: David S.

| | | | | | | | | | | | | | | It is clean-up for XFRM type modules and adds aliases with its protocol: ESP, AH, IPCOMP, IPIP and IPv6 for IPsec ROUTING and DSTOPTS for MIPv6 It is almost the same thing as XFRM mode alias, but it is added new defines XFRM_PROTO_XXX for preprocessing since some protocols are defined as enum.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes MIPv6 loadable module named "mip6". Here is a modprobe.conf(5) example to load it automatically when user application uses XFRM state for MIPv6: alias xfrm-type-10-43 mip6 alias xfrm-type-10-60 mip6 Some MIPv6 feature is not included by this modular, however, it should not be affected to other features like either IPsec or IPv6 with and without the patch. We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt separately for future work. Loadable features: * MH receiving check (to send ICMP error back) * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS) * XFRM policy/state database handling for RO These are NOT covered as loadable: * Home Address flags and its rule on source address selection * XFRM sub policy (depends on its own kernel option) * XFRM functions to receive RO as IPv6 extension header * MH sending/receiving through raw socket if user application opens it (since raw socket allows to do so) * RH2 sending as ancillary data * RH2 operation with setsockopt(2) Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

* [RTNETLINK]: Add nested compat attributePatrick McHardy2007-07-101-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a nested compat attribute type that can be used to convert attributes that contain a structure to nested attributes in a backwards compatible way. The attribute looks like this: struct { [ compat contents ] struct rtattr { .rta_len = total size, .rta_type = type, } rta; struct old_structure struct; [ nested top-level attribute ] struct rtattr { .rta_len = nest size, .rta_type = type, } nest_attr; [ optional 0 .. n nested attributes ] struct rtattr { .rta_len = private attribute len, .rta_type = private attribute typ, } nested_attr; struct nested_data data; }; Since both userspace and kernel deal correctly with attributes that are larger than expected old versions will just parse the compat part and ignore the rest.
