Date: Tue, 10 Apr 2012 01:00:44 +0200 From: "Stian Skjelstad" <stian@...ia.no> To: linux-kernel@...r.kernel.org Subject: Is this intended design, or a bug? Missing event for gateway being deleted I'm sorry if this has been discussed before, but my google searches didn't give me any good hints so: I'm using rtnetlink for a project and I noticed a non-consistent behavior. When I tear down (the last) ip address, the default gateway is removed, but it is not announced on the netlink socket. This can also be verified using "ip monitor". This is tested with linux kernel version 3.2.6 on ARM. # ip monitor & # ip addr add 10.0.0.2/8 dev eth0 2: eth0 inet 10.0.0.2/8 scope global eth0 local 10.0.0.2 dev eth0 table local proto kernel scope host src 10.0.0.2 10.0.0.0/8 dev eth0 proto kernel scope link src 10.0.0.2 broadcast 10.0.0.0 dev eth0 table local proto kernel scope link src 10.0.0.2 broadcast 10.255.255.255 dev eth0 table local proto kernel scope link src 10.0.0.2 # ip route add via 10.0.1.22 default via 10.0.1.2 dev eth0 # ip addr del 10.0.0.2/8 dev eth0 Deleted 2: eth0 inet 10.0.0.2/8 scope global eth0 Deleted 10.0.0.0/8 dev eth0 proto kernel scope link src 10.0.0.2 Deleted broadcast 10.255.255.255 dev eth0 table local proto kernel scope link src 10.0.0.2 Deleted broadcast 10.0.0.0 dev eth0 table local proto kernel scope link src 10.0.0.2 Deleted local 10.0.0.2 dev eth0 table local proto kernel scope host src 10.0.0.2 (No Deleted default via line here) Stian Skjelstad -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
