No special workarounds in my package that I'm aware of! My guess would
be that it's inconsistent between netlink families. I've only really
played with genetlink and rtnetlink.

Hmm fails with EPERM when we try to listen for CN_IDX_PROC I guess that
may be a special case given what it is.
Be interested to know if your module avoids this issue somehow?

This appears not to be true, at least in the case of rtnetlink and
listening to multicast notifications for link additions and removals.

It's required for read only in some situations too, for example we use
it here to listen for process exit codes.

Sure, I can make a note of this. Almost everything I've done with netlink
so far has been read-only, which is probably why I haven't run into any
issues.

One thing you don't mention, which we found particularly frustrating
with netlink, is that using it can often need cap_net_admin :(

I recently spent some time working with Linux's netlink IPC mechanism in
