* [IPv4]: FIB configuration using struct fib_configThomas Graf2006-09-22
| | | | | | | | | | | | | | | Introduces struct fib_config replacing the ugly struct kern_rta prone to ordering issues. Avoids creating faked netlink messages for auto generated routes or requests via ioctl. A new interface net/nexthop.h is added to help navigate through nexthop configuration arrays. A new struct nl_info will be used to carry the necessary netlink information to be used for notifications later on. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

* [IPV4]: Increase number of possible routing tables to 2^32Patrick McHardy2006-09-22
| | | | | | | | | Increase the number of possible routing tables to 2^32 by replacing the fixed sized array of pointers by a hash table and replacing iterations over all possible table IDs by hash table walking.

* [NET]: Introduce RTA_TABLE/FRA_TABLE attributesPatrick McHardy2006-09-22
| | | | | | | | | | | | Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute to hold 32 bit routing table IDs. Usespace compatibility is provided by continuing to accept and send the rtm_table field, but because of its limited size it can only carry the low 8 bits of the table ID. This implies that if larger IDs are used, _all_ userspace programs using them need to use RTA_TABLE. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Use u32 for routing table IDsPatrick McHardy2006-09-22
| | | | | | | | | | Use u32 for routing table IDs in net/ipv4 and net/decnet in preparation of support for a larger number of routing tables. net/ipv6 already uses u32 everywhere and needs no further changes. No functional changes are made by this patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [IPV4]: Use network-order dport for all visible inet_lookup_*Herbert Xu2006-09-22
| | | | | | | | | | | | | | | | Right now most inet_lookup_* functions take a host-order hnum instead of a network-order dport because that's how it is represented internally. This means that users of these functions have to be careful about using the right byte-order. To add more confusion, inet_lookup takes a network-order dport unlike all other functions. So this patch changes all visible inet_lookup functions to take a dport and move all dport->hnum conversion inside them.

* [IPV4] fib: convert reader/writer to spinlockStephen Hemminger2006-09-22
| | | | | | | | | Ther is no point in using a more expensive reader/writer lock for a low contention lock like the fib_info_lock. The only reader case is in handling route redirects. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4]: Uninline inet_lookup_listenerHerbert Xu2006-09-22

| | | | | | | | | | | Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose checksum still needs to be completed) and CHECKSUM_COMPLETE (for incoming packets, device supplied full checksum).

* [NetLabel]: CIPSOv4 enginePaul Moore2006-09-22
| | | | | | | | | | | | | | | | | | | | | Add support for the Commercial IP Security Option (CIPSO) to the IPv4 network stack. CIPSO has become a de-facto standard for trusted/labeled networking amongst existing Trusted Operating Systems such as Trusted Solaris, HP-UX CMW, etc. This implementation is designed to be used with the NetLabel subsystem to provide explicit packet labeling to LSM developers. The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API function which attaches a CIPSO label (IPv4 option) to a given socket; this in turn attaches the CIPSO label to every packet leaving the socket without any extra processing on the outbound side. On the inbound side the individual packet's sk_buff is examined through a call to a NetLabel API function to determine if a CIPSO/IPv4 label is present and if so the security attributes of the CIPSO label are returned to the caller of the NetLabel API function.

* [MLSXFRM]: Auto-labeling of child socketsVenkat Yekkirala2006-09-22
| | | | | | | | | | | | | This automatically labels the TCP, Unix stream, and dccp child sockets as well as openreqs to be at the same MLS level as the peer. This will result in the selection of appropriately labeled IPSec Security Associations. This also uses the sock's sid (as opposed to the isec sid) in SELinux enforcement of secmark in rcv_skb and postroute_last hooks.

* [MLSXFRM]: Add flow labelingVenkat Yekkirala2006-09-22
| | | | | | | | | | | | | | | | | | | | | | This labels the flows that could utilize IPSec xfrms at the points the flows are defined so that IPSec policy and SAs at the right label can be used. The following protos are currently not handled, but they should continue to be able to use single-labeled IPSec like they currently do. ipmr ip_gre ipip igmp sit sctp ip6_tunnel (IPv6 over IPv6 tunnel device) decnet Signed-off-by: Venkat Yekkirala <vyekkirala@TrustedCS.com> Signed-off-by: David S.

* [IPSEC]: Use HMAC template and hash interfaceHerbert Xu2006-09-20
| | | | | | | | | | | | | This patch converts IPsec to use the new HMAC template. The names of existing simple digest algorithms may still be used to refer to their HMAC composites. The same structure can be used by other MACs such as AES-XCBC-MAC. This patch also switches from the digest interface to hash.

* [IPSEC] ESP: Use block ciphers where applicableHerbert Xu2006-09-20
| | | | | | | | This patch converts IPSec/ESP to use the new block cipher type where applicable. Similar to the HMAC conversion, existing algorithm names have been kept for compatibility. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
