ipv4: fix nexthop attlen check in fib_nh_match

2015-05-24T08:10:53Z

commit f76936d07c4eeb36d8dbb64ebd30ab46ff85d9f7 upstream. fib_nh_match does not match nexthops correctly. Example: ip route add 172.16.10/24 nexthop via 192.168.122.12 dev eth0 \ nexthop via 192.168.122.13 dev eth0 ip route del 172.16.10/24 nexthop via 192.168.122.14 dev eth0 \ nexthop via 192.168.122.15 dev eth0 Del command is successful and route is removed. After this patch applied, the route is correctly matched and result is: RTNETLINK answers: No such process Please consider this for stable trees as well.

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: Fix routing tables with id > 255 for legacy software

2008-06-10T22:44:49Z

Most legacy software do not like tables > 255 as rtm_table is u8 so tb_id is sent &0xff and it is possible to mismatch for example table 510 with table 254 (main). This patch introduces RT_TABLE_COMPAT=252 so the code uses it if tb_id > 255. It makes such old applications happy, new ones are still able to use RTA_TABLE to get a proper table id.

[NETNS]: Lookup in FIB semantic hashes taking into account the namespace.

2008-02-01T03:28:41Z

The namespace is not available in the fib_sync_down_addr, add it as a parameter. Looking up a device by the pointer to it is OK. Looking up using a result from fib_trie/fib_hash table lookup is also safe. No need to fix that at all. So, just fix lookup by address and insertion to the hash table path. Signed-off-by: Denis V.

[NETNS]: Add a namespace mark to fib_info.

2008-02-01T03:28:40Z

This is required to make fib_info lookups namespace aware. In the other case initial namespace devices are marked as dead in the local routing table during other namespace stop. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller
