net: Allow fib_rule_unregister to batch

2009-12-03T20:22:55Z

Refactor the code so fib_rules_register always takes a template instead of the actual fib_rules_ops structure that will be used. This is required for network namespace support so 2 out of the 3 callers already do this, it allows the error handling to be made common, and it allows fib_rules_unregister to free the template for hte caller. Modify fib_rules_unregister to use call_rcu instead of syncrhonize_rcu to allw multiple namespaces to be cleaned up in the same rcu grace period. Signed-off-by: Eric W.

net 04/05: fib_rules: allow to delete local rule

2009-12-03T20:14:37Z

commit d124356ce314fff22a047ea334379d5105b2d834 Author: Patrick McHardy Date: Thu Dec 3 12:16:35 2009 +0100 net: fib_rules: allow to delete local rule Allow to delete the local rule and recreate it with a higher priority. This can be used to force packets with a local destination out on the wire instead of routing them to loopback. Additionally this patch allows to recreate rules with a priority of 0. Combined with the previous patch to allow oif classification, a socket can be bound to the desired interface and packets routed to the wire like this: # move local rule to lower priority ip rule add pref 1000 lookup local ip rule del pref 0 # route packets of sockets bound to eth0 to the wire independant # of the destination address ip rule add pref 100 oif eth0 lookup 100 ip route add default dev eth0 table 100 Signed-off-by: Patrick McHardy Signed-off-by: David S.

net 03/05: fib_rules: add oif classification

2009-12-03T20:14:36Z

commit 68144d350f4f6c348659c825cde6a82b34c27a91 Author: Patrick McHardy Date: Thu Dec 3 12:05:25 2009 +0100 net: fib_rules: add oif classification Support routing table lookup based on the flow's oif. This is useful to classify packets originating from sockets bound to interfaces differently. The route cache already includes the oif and needs no changes.

net 02/05: fib_rules: rename ifindex/ifname/FRA_IFNAME to iifindex/iifname/FRA_IIFNAME

net: Remove unused parameter from fill method in fib_rules_ops.

2009-05-21T00:26:23Z

The netlink message header (struct nlmsghdr) is an unused parameter in fill method of fib_rules_ops struct. This patch removes this parameter from this method and fixes the places where this method is called. (include/net/fib_rules.h) Signed-off-by: Rami Rosen Signed-off-by: David S. Miller

netlink: change nlmsg_notify() return value logic

2009-02-25T07:18:28Z

This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

net: fib_rules ordering fixes.

2008-11-08T06:52:34Z

We need to setup the network namespace state before we register the notifier. Otherwise if a network device is already registered we get a nasty NULL pointer dereference. Signed-off-by: Eric W. Biederman Signed-off-by: David S. Miller
