CONFIG_CAN disabled in kernel

Bug #327243 reported by yope on 2009-02-09

Affects		Status	Importance	Assigned to	Milestone

Bug Description

Binary package hint: linux-image

lsb_release -rd:
Description: Ubuntu 8.10
Release: 8.10
package: linux-image-2.6.27-9-generic

CONFIG_CAN is not defined in the kernel configuration, making it hard to user the Socket-CAN protocol introduced in kernel 2.6.25.
It should be trivial to enable the following options:

CONFIG_CAN=y
CONFIG_CAN_RAW=y
CONFIG_CAN_BCM=y
CONFIG_CAN_VCAN=y

That way one could actually use CAN interfaces (like Peak CAN) on ubuntu linux with the new socket-CAN API. One of the main reasons I upgraded in the first place ;-)

Still looks disabled for karmic. Setting this to Triaged.

Does CAN need in Ubuntu?!

Yes of course! There are numerous CAN network interfaces available for PC's, let alone embedded systems (where Ubuntu is also quite popular). Besides, it doesn't cost much to enable those modules in the kernel.
At our company we use ubuntu on several workstations, and we have CAN adapters on most of them. It is a hassle to have to compile my own kernel for each new release just because that one thing isn't enabled in the stock kernel.
Even more so, to have to explain to our customers the procedure to get this custom kernel installed on their ubuntu-systems in order to run our software!
