Hi Stephen (and others),

I'm trying to move the functionality from a small user space tool I wrote for 
listening to HSR Netlink messages into iproute2. The tool uses generic netlink 
through libnl3. 

It seems iproute2 uses libnl-1 though:

iphsr.c:325:6: warning: 'struct nl_sock' declared inside parameter list
iphsr.c:334:30: error: 'NL_AUTO_PORT' undeclared (first use in this function)
iphsr.c:341:2: warning: implicit declaration of function 'nl_send_auto'
iphsr.c:417:2: warning: implicit declaration of function 'genl_ctrl_resolve_grp'
iphsr.c:424:2: warning: implicit declaration of function 'nl_socket_add_memberships'
iphsr.c:455:2: warning: implicit declaration of function 'nl_socket_alloc'
iphsr.c:463:2: warning: implicit declaration of function 'nl_socket_disable_seq_check'

Are there alternatives to the above functionality in libnl-1, or do I need to 
implement it myself (copy them from the libnl3 code perhaps)?

Upstream version of iproute does not use libnl.
Any patches to use libnl are rejected. iproute2 has its own internal libnetlink  library.
