net: Dont use ifindices in hash fns

2012-08-09T23:18:06Z

Eric noticed, that when there will be devices with equal indices, some hash functions that use them will become less effective as they could. Fix this in advance by mixing the net_device address into the hash value instead of the device index. This is true for arp and ndisc hash fns. The netlabel, can and llc ones are also ifindex-based, but that three are init_net-only, thus will not be affected. Many thanks to David and Eric for the hash32_ptr implementation!

ipv4: Fix neigh lookup keying over loopback/point-to-point devices.

2012-07-20T23:06:10Z

We were using a special key "0" for all loopback and point-to-point device neigh lookups under ipv4, but we wouldn't use that special key for the neigh creation. So basically we'd make a new neigh at each and every lookup :-) This special case to use only one neigh for these device types is of dubious value, so just remove it entirely.

ipv4: Make neigh lookups directly in output packet path.

2012-07-05T08:02:12Z

Do not use the dst cached neigh, we'll be getting rid of that. Signed-off-by: David S. Miller

ipv4: Eliminate spurious argument to __ipv4_neigh_lookup

2012-02-15T22:48:35Z

'tbl' is always arp_tbl, so specifying it is pointless. Signed-off-by: David S. Miller

ipv6: Use universal hash for NDISC.

2011-12-28T20:06:58Z

In order to perform a proper universal hash on a vector of integers, we have to use different universal hashes on each vector element. Which means we need 4 different hash randoms for ipv6. Signed-off-by: David S. Miller

net: Add ->neigh_lookup() operation to dst_ops

2011-07-18T07:40:17Z

In the future dst entries will be neigh-less. In that environment we need to have an easy transition point for current users of dst->neighbour outside of the packet output fast path. Signed-off-by: David S. Miller

ipv4: Inline neigh binding.

2011-07-13T08:12:28Z

Get rid of all of the useless and costly indirection by doing the neigh hash table lookup directly inside of the neighbour binding. Rename from arp_bind_neighbour to rt_bind_neighbour. Use new helpers {__,}ipv4_neigh_lookup() In rt_bind_neighbour() get rid of useless tests which are never true in the context this function is called, namely dev is never NULL and the dst->neighbour is always NULL.

ipv4: Use universal hash for ARP.

2011-07-11T08:37:28Z

We need to make sure the multiplier is odd. Signed-off-by: David S. Miller

arp: allow to invalidate specific ARP entries

2011-01-11T00:10:37Z

IPv4 over firewire needs to be able to remove ARP entries from the ARP cache that belong to nodes that are removed, because IPv4 over firewire uses ARP packets for private information about nodes. This information becomes invalid as soon as node drops off the bus and when it reconnects, its only possible to start talking to it after it responded to an ARP packet. But ARP cache prevents such packets from being sent. Signed-off-by: Maxim Levitsky Signed-off-by: David S. Miller

arp: remove unnecessary export of arp_broken_ops

2010-09-30T02:45:35Z

arp_broken_ops is only used in arp.c Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller
