Revision 731abb9cb27aef6013ce60808a04e04a545f3f4e authored by Josh Boyer on 10 November 2011, 15:10:23 UTC, committed by David S. Miller on 14 November 2011, 05:24:06 UTC
Commit 1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create because register_netdevice will now create a valid name. This works for the net_device itself. However the tunnel keeps a copy of the name in the parms structure for the ip6_tnl associated with the tunnel. parms.name is set by copying the net_device name in ip6_tnl_dev_init_gen. That function is called from ip6_tnl_dev_init in ip6_tnl_create, but it is done before register_netdevice is called so the name is set to a bogus value in the parms.name structure. This shows up if you do a simple tunnel add, followed by a tunnel show: [root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200 [root@localhost ~]# ip -6 tunnel show ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) ip6tnl%d: ipv6/ipv6 remote fec0::100 local fec0::200 encaplimit 4 hoplimit 64 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) [root@localhost ~]# Fix this by moving the strcpy out of ip6_tnl_dev_init_gen, and calling it after register_netdevice has successfully returned.
