Looks like only OSPF prefixes appear there, although my kernel protocol 
was configured with "import none":

I don't see anything, but I've added "log stderr all" and "debug 
protocols all" to my config, and have pasted the output of "bird -d" here:

The first of the Netlink errors occurs at line 720, and just repeats 
after that.

So with static routes defined in bird's config, I don't get the Netlink 
errors on them.  They appear in 'ip route list', and on other OSPF 
routers.  Config and debug startup pasted here:

With learn commented, the Netlink errors still occur.

Mmm, yes, this is strange.  I'm not able to import static routes from 
the Linux kernel.  They don't show in birdc's "show route" output and 
don't get exported to OSPF.  I've pasted 'ip route list' output, bird 
config, debug startup, and bird routes here:

Thank you, Ondrej, for looking at this. :)
