Thanks for this bug report Can you post the original Netlink request message as well? The one preceeding the error message. |
|
Damn, error in copy/paste sorry. There is the full capture : -- Debug: Sent Message: 127.0.0.1/8 inet dev lo scope host Same result on kernel : Linux ubuntu 2.6.32-57-generic and 3.2.0 |

Without looking deep into this, it could be the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1063885#c22 Could you please retry with removing the line https://github.com/thom311/libnl/blob/master/lib/route/addr.c#L601 ? |
|
You got'it that resolve the problem. Thanks for the fast response. |
|
Interesting. But it's not really the solution, because this line should be correct and is actually needed. Could you please give more information about the system where this happens? Kernel version, architecture, ubuntu-version |
|
Informations about the first system (a little old) : Full uname -a : The ip configuration : NetworkManager is running The second system : |
|
I agree that this is a kernel bug but I can't reproduce this on a 3.13 kernel. |

Hi,
i am working on the 3.2.24 version of libnl, and i think there are a bug on the rtnl_addr_add and rtnl_addr_delete.
Even the test library in src fail to remove a route with interactive command :
swissdotnet@ubuntu:~/networkManager/workspace/libnl/libnl-3.2.24/src$ sudo ./nl-addr-delete -i
127.0.0.1/8 inet dev lo scope host
Delete? (y/N) n
10.110.0.247/24 inet dev eth3 scope global
Delete? (y/N) y
Error: Unable to delete address: Invalid input data or parameter
With debug informations :

I have check with version 3.2.7 and i have no problem with this version.
Thanks
