Looks much better now! There are message for state changes to error
warning and passive. Just the following message is not correct:

 (000.200824)  can0  20000004   [8]  00 40 00 00 00 00 5F 19
ERRORFRAME
    controller-problem{}
    error-counter-tx-rx{{95}{25}}

Sorry, forgot to mention... the function can_change_state() [1]
should be used for that purpose, if possible. It fixes the issue
above as well.

The updated driver (the one used to create the above log) is using
can_change_state() function. data[1] 40 corresponds to
CAN_ERR_CRTL_ACTIVE, so looks correct? Could it be that the can-utils I
am using is old and not reporting state change?

Hm, yes. The raw data looks correct. You could download and build a
recent version from "https://github.com/linux-can/can-utils" to check.
It could also be a bug.

Support for that flags has been added in December 2014.
