Hi Evgeniy, I am not quite sure how to assign nl_groups when using connector. You Documentation/connector/connector.txt don't explain it very clearly. I thought it's a bitmask representing only 32 groups. If I just want to subscribe only one group such as CN_KVP_IDX, what shall I do? Which one below is correct? a) l_local.nl_groups = CN_KVP_IDX; Or b) l_local.nl_groups = 1 << (CN_KVP_IDX -1) and bind with bind(s, (struct sockaddr *)&l_local, sizeof(struct sockaddr_nl)). I ran your example in Documentation/connector/. 'l_local.nl_groups = -1' in ucon.c seems subscribe all channels, because if I start cgred service, ucon will receive messages with idx=1. And it seems setsockopt is not needed now, for it is done by netlink_autobind? You even comment it out using '#if 0' in Documentation/connector/ucon.c. Could you do me a favor to check http://driverdev.linuxdriverproject.org/pipermail/devel/2013-March/036306.html to see if my understanding is correct or not? Thanks. -- Regards, Vaughan _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
