* [DECNET]: Increase number of possible routing tables to 2^32Patrick McHardy2006-09-224-86/+93
| | | | | | | | | 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 McHardy2006-09-2213-12/+45
| | | | | | | | | | | | 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 McHardy2006-09-2210-31/+31
| | | | | | | | | | 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>
* [NEIGHBOUR]: Use ALIGN() macro.Stephen Hemminger2006-09-221-1/+1
| | | | | | | | Rather than opencoding the mask, it looks better to use ALIGN() macro from kernel.h. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NET]: sock_register interface changesStephen Hemminger2006-09-222-8/+6
| | | | | | | | | The sock_register() doesn't change the family, so the protocols can define it read-only. No caller ever checks return value from sock_unregister() Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: socket family using RCUStephen Hemminger2006-09-221-98/+76

* [DECNET]: Covert rules to use generic codeSteven Whitehouse2006-09-229-319/+196

* [IPV4]: Use network-order dport for all visible inet_lookup_*Herbert Xu2006-09-224-26/+43
| | | | | | | | | | | | | | | | 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 Hemminger2006-09-221-10/+10
| | | | | | | | | 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>
* [IPV6]: Make sure fib6_rule_lookup doesn't return NULLVille Nuorvala2006-09-221-1/+5
| | | | | | | | The callers of fib6_rule_lookup don't expect it to return NULL, therefore it must return ip6_null_entry whenever fib_rule_lookup fails. Signed-off-by: Ville Nuorvala <vnuorval@tcs.hut.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4]: Uninline inet_lookup_listenerHerbert Xu2006-09-222-34/+34
| | | | | | | | By modern standards this function is way too big to be inlined. It's even bigger than __inet_lookup_listener :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [INET]: Remove is_setbyuser patchLouis Nyffenegger2006-09-222-4/+1
| | | | | | | | | The value is_setbyuser from struct ip_options is never used and set only one time (http://linux-net.osdl.org/index.php/TODO#IPV4).

Also moves bits to be exported to userspace from net/neighbour.h to linux/neighbour.h and removes __KERNEL__ guards, userspace is not supposed to be using it. rtnetlink_rcv_msg() is not longer required to parse attributes for the neighbour layer, remove dependency on obsolete and buggy rta_buf.

* [IPV6]: Fix policy routing lookupPatrick McHardy2006-09-221-1/+3
| | | | | | | | | When the lookup in a table returns ip6_null_entry the policy routing lookup returns it instead of continuing in the next table, which effectively means it only searches the local table.

| | | | | | | | | | | 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).

* [NET]: Convert link dumping to new netlink apiThomas Graf2006-09-221-144/+137
| | | | | | | | | | | | | Transforms netlink code to dump link tables to use the new netlink api. Makes rtnl_getlink() available regardless of the availability of the wireless extensions. Adding copy_rtnl_link_stats() avoids the structural dependency of struct rtnl_link_stats on struct net_device_stats and thus avoids troubles later on.

| | | | | | | | | | | | | Transforms do_setlink() into rtnl_setlink() using the new netlink api. A warning message printed to the console is added in the event that a change request fails while part of the change request has been comitted already. The ioctl() based nature of net devices makes it almost impossible to move on to atomic netlink operations without obsoleting some of the functionality.
