Hi Wolfgang, we currently face an issue regarding the filtering of CAN messages since Xenomai 2.4. It was introduced in rev. 2202 (I know it is long ago but the problem popped up last week). The line in question is
http://www.rts.uni-hannover.de/xenomai/lxr/source/ksrc/drivers/can/rtcan_raw_filter.c?v=2.3.5#064 and http://www.rts.uni-hannover.de/xenomai/lxr/source/ksrc/drivers/can/rtcan_raw_filter.c?v=2.4.4#062 respectively. What worries me is the removal of the AND-operation (can_id & can_mask). From my POV this offends the CAN specification which says that the CAN filter mask shall indicate which bits are taken into account when comparing a CAN identifier and which shall be seen as "don't care". From your Changelog entry the reason for this modification was to be up to date with the Linux Socket CAN project. So maybe there is also the need to bring up this topic on their ML, too. -- Sebastian _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
