libnl userspace to userspace

[Veytser, Leonid - 0665 - MITLL]

Looking through genetlink.h file I notice that among the control commands
there are CTRL_CMD_NEWFAMILY and CTRL_CMD_NEWMCAST_GRP commands defined.
Does this mean that in theory there is a facility to create new generic
netlink families and new multicast groups from userspace?

Thanks,

Lenny

I am trying to do the same thing actually. I am able to send and receive
netlink messages between userspace processes as long as the genl family is
registered by a kernel module. I am trying to remove the requirement of
needing this module and register the family from userspace. However, judging
by your last message that is not currently possible? Is that correct?

Thanks,

Lenny
