htb qdisc malfunctions

[GSMD]

Binary package hint: linux-source-2.6.22

--
tc qdisc add dev ppp0 root handle 3:0 htb default 30
tc class add dev ppp0 parent 3:0 classid 3:1 htb rate 220kbit #for a 256k link
# the default one
tc class add dev ppp0 parent 3:1 classid 3:30 htb rate 10kbit ceil 220kbit burst 6k prio 3
# for p2p traffic
tc class add dv ppp0 parent 3:1 classid 3:50 htb rate 5kbit ceil 6kbit prio 5
# p2p client running on LAN and port 10720 is DNATed to ppp0
tc filter add dev ppp0 parent 3: protocol ip u32 match ip sport 10720 0xff flowid 3:50

Now, consider 2 options: 1)the last line is commented out and 2)the last line is uncommented.
1) p2p traffic gets to the default class 3:30 and shapes accordingly to ceil. No prob here.
2) p2p traffic gets to 3:50 (checked with 'tc -s -d class show dev ppp0', it really does) and consumes all the bandwidth (uploading files)! The ceil of 6 kbytes doesn't matter at all!

Not sure how much this will help as I'm not completely familiar with manipulating traffic control settings. However, the Hardy Heron Alpha series is currently under development and contains an updated version of the kernel. It would be helpful if you could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. Thanks.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
