AFAIK the can-raw socket also supports polling:
static struct proto_ops raw_ops __read_mostly = {
.family = PF_CAN,
.release = raw_release,
.bind = raw_bind,
.connect = sock_no_connect,
.socketpair = sock_no_socketpair,
.accept = sock_no_accept,
.getname = raw_getname,
.poll = datagram_poll,
(..)
I use select() in many cases - but currently only for reading from
filedescriptors ...

Oliver
