Hi, Based on Andrew Atrens previous work, I'm trying to bring netgraph up to date with FreeBSD. The latest patch I have can be downloaded from [1]. It builds but it's not yet working. I'm posting this message to ask for guidance as there is a lot to learn.
1) Locking. I have directly replaced all FreeBSD mutexes to lwkt_serialize locks on DragonFly, and all spl calls to critical sections. Is this the correct way to do this? 2) I think I'm having trouble with tsleep/wakeup in ng_socket. I'm testing using a vkernel, the configuration is at [2]. Inside the vkernel if I test the command 'ngctl list', ngctl will sleep (because of ng_socket tsleep) and then never wakes up again. A netisr is scheduled and should eventually wake up ngctl, but this doesn't seem to happen. I will keep looking, but I just wanted to post this just in case someone more experienced has a suggestion :-) . Thanks, Nuno [1] http://leaf.dragonflybsd.org/~nant/wip/netgraph-20071115.patch.gz [2] http://leaf.dragonflybsd.org/~nant/wip/NETGRAPH.VKERNEL
