ipv4: Flush per-ns routing cache more sanely.

2010-12-20T18:37:19Z

Flush the routing cache only of entries that match the network namespace in which the purge event occurred. Signed-off-by: David S. Miller Acked-by: Eric Dumazet

ipv4: Don't pre-seed hoplimit metric.

2010-12-13T06:08:17Z

Always go through a new ip4_dst_hoplimit() helper, just like ipv6. This allowed several simplifications: 1) The interim dst_metric_hoplimit() can go as it's no longer userd. 2) The sysctl_ip_default_ttl entry no longer needs to use ipv4_doint_and_flush, since the sysctl is not cached in routing cache metrics any longer. 3) ipv4_doint_and_flush no longer needs to be exported and therefore can be marked static. When ipv4_doint_and_flush_strategy was removed some time ago, the external declaration in ip.h was mistakenly left around so kill that off too. We have to move the sysctl_ip_default_ttl declaration into ipv4's route cache definition header net/route.h, because currently net/ip.h (where the declaration lives now) has a back dependency on net/route.h Signed-off-by: David S.

net: use the macros defined for the members of flowi

Use the macros defined for the members of flowi to clean the code up. Signed-off-by: Changli Gao Signed-off-by: David S. Miller

ipv4: Make rt->fl.iif tests lest obscure.

2010-11-12T01:07:48Z

When we test rt->fl.iif against zero, we're seeing if it's an output or an input route. Make that explicit with some helper functions. Signed-off-by: David S. Miller

net: get rid of rtable->idev

2010-11-11T18:29:40Z

It seems idev field in struct rtable has no special purpose, but adding extra atomic ops. We hold refcounts on the device itself (using percpu data, so pretty cheap in current kernel). infiniband case is solved using dst.dev instead of idev->dev Removal of this field means routing without route cache is now using shared data, percpu data, and only potential contention is a pair of atomic ops on struct neighbour per forwarded packet. About 5% speedup on routing test. Signed-off-by: Eric Dumazet Cc: Herbert Xu Cc: Roland Dreier Cc: Sean Hefty Cc: Hal Rosenstock Signed-off-by: David S. Miller

net-next: remove useless union keyword

2010-06-11T06:31:35Z

remove useless union keyword in rtable, rt6_info and dn_route. Since there is only one member in a union, the union keyword isn't useful. Signed-off-by: Changli Gao Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: implements ip_route_input_noref()

2010-05-18T00:18:51Z

ip_route_input() is the version returning a refcounted dst, while ip_route_input_noref() returns a non refcounted one. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

percpu: add __percpu sparse annotations to net

2010-02-17T07:05:38Z

Add __percpu sparse annotations to net. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds. The macro and type tricks around snmp stats make things a bit interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All snmp_mib_*() users which used to cast the argument to (void **) are updated to cast it to (void __percpu **). Signed-off-by: Tejun Heo Acked-by: David S.

net: NETDEV_UNREGISTER_PERNET -> NETDEV_UNREGISTER_BATCH

2009-12-02T00:15:50Z

The motivation for an additional notifier in batched netdevice notification (rt_do_flush) only needs to be called once per batch not once per namespace. For further batching improvements I need a guarantee that the netdevices are unregistered in order allowing me to unregister an all of the network devices in a network namespace at the same time with the guarantee that the loopback device is really and truly unregistered last. Additionally it appears that we moved the route cache flush after the final synchronize_net, which seems wrong and there was no explanation. So I have restored the original location of the final synchronize_net. Cc: Octavian Purdila Signed-off-by: Eric W. Biederman Signed-off-by: David S. Miller
