Hi,
I have next dummynet configuration:
ipfw pipe 3 bw 3Mbit/s
ipfw queue 10 config pipe 3 weight 10 mask src-ip 0xffffffff
ipfw queue 11 config pipe 3 weight 10 mask dst-ip 0xffffffff
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.
