Round 3 Changes: - changed netlink msg for neighbour change to (RTM_NEIGHUPD) - added netlink msg for PMTU change events (RTM_ROUTEUPD) - added netlink messages for redirect (RTM_DELROUTE + RTM_NEWROUTE) - tested neighbour change events via netlink for ipv4 and ipv6. - tested redirect change events via netlink for ipv4.
Round 2 Changes: - cleaned up event structures per review feedback. - began integration with netlink (see neighbour changes in patch 2). - added IPv6 support. TODO: - review feedback changes, if any - more testing - retest with RDMA NIC ------ This patch implements a mechanism that allows interested clients to register for notification of certain network events. The intended use is to allow RDMA devices (linux/drivers/infiniband) to be notified of neighbour updates, ICMP redirects, path MTU changes, and route changes. The reason these devices need update events is because they typically cache this information in hardware and need to be notified when this information has been updated. For information on RDMA protocols, see: http://www.ietf.org/html.charters/rddp-charter.html. The key events of interest are: - neighbour mac address change - routing redirect (the next hop neighbour changes for a dst_entry) - path mtu change (the path mtu for a dst_entry changes). - route add/deletes NOTE: These new netevents are also passed up to user space via netlink. We would like to get this or similar functionality included in 2.6.19 and request comments. This patchset consists of 2 patches: 1) New files implementing the Network Event Notifier 2) Core network changes to generate network event notifications Signed-off-by: Tom Tucker <[EMAIL PROTECTED]> Signed-off-by: Steve Wise <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
