Yes. Think about the multi-user capabilities of your system.
You may open many CAN_BCM sockets as well as CAN_RAW sockets.
When creating a CAN_RAW socket you may use it as-is (and get all CAN traffic)
or you may filter the CAN_RAW socket by CAN-ID filters (see documentation):
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=Documentation/networking/can.txt;h=820f55344edc0a035358fa643bbe79c48d4d887f;hb=HEAD#l424
Additionally you may create one or more CAN_BCM sockets to create BCM jobs to
send CAN frames periodically or to detect payload changes in received
messages as well as timeouts.

Oliver
