GSoC - SeND
Hi all, I am Ana Kukec, a research assistant and a PhD student at University of Zagreb. I will be working on the IPv6 Secure Neighbor Discovery (SeND - rfc3971, rfc4861) - the implementation of native kernel APIs for FreeBSD, within GSoC, with my mentor Bjoern Zeeb. More informations will be provided on http://wiki.freebsd.org/SOC2009AnaKukec.

[dummynet] Several queues connected to one pipe: "dummynet: OUCH! pipe should have been idle!"
Hi, I have next dummynet configuration: ipfw pipe 3 bw 3Mbit/s ipfw queue 10 config pipe 3 weight 10 mask src-ip 0x ipfw queue 11 config pipe 3 weight 10 mask dst-ip 0x Two queues for different traffic directions connected to one pipe. After update to r191410 my /var/log/messages filled with: Apr 24 16:33:31 imax kernel: dummynet: OUCH! pipe should have been idle! Apr 24 16:33:59 imax last message repeated 8 times Apr 24 16:35:53 imax last message repeated 519 times Apr 24 16:38:55 imax last message repeated 50 times Then I've changed ip_dummynet.c little, to see actual value of pipe->scheduler_heap.elements Here what I've got with one dynamic queue per parent: Apr 25 16:16:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 2 Apr 25 16:17:05 imax last message repeated 462 times Apr 25 16:18:48 imax last message repeated 1269 times With two queues per parent: Apr 26 16:51:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 4 Apr 26 16:51:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 3 Apr 26 16:51:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 4 Apr 26 16:51:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 3 Apr 26 16:51:34 imax kernel: dummynet: OUCH! pipe should have been idle!SCH len: 4 Thanks for attention, awaiting your comments and/or suggestions. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

Could you double check what is the last working version ? cheers luigi ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

I use HEAD, and before update it was r191201, if I'm not mistaking. Now I'm just removed queues from ruleset, but I may supply any additional information, if needed.
