[PATCH] smbd: receive IP address changes via our addrchange netlink API

[Ralph Wuerthner]

Hi list,

some time ago I received the attached patch from Ralph Boehme to make 
smbd close the SMB session if the local IP address is dropped. We use 
this on a Samba/CTDB cluster where CTDB is not managing the IP addresses.
To get this feature into master I was thinking on writing a test case to 
automatically test this feature in autobuild. But I'm a little bit lost 
on how to write such a test case because it involves adding and removing 
a local IP address in order to test this. Do I have to enhance 
socket_wrapper to emulate the kernel netlink interface? Or are there any 
other ideas?

Any help is appreciated!

Regards

Ralph
