Description of problem: When I setup a GRED Queue in grio mode, the VQs prio parameter should be configurable. But somehow it is always set to the default value, no matter what value I try to set it to. Version-Release number of selected component: Package: iproute-2.6.33-8.fc13(i686) -> tc utility, iproute2-ss100224 Package: kernel-2.6.34.8-68.fc13(i686) How reproducible: ALWAYS Steps to Reproduce: tc qdisc add dev eth0 root gred setup DPs 3 default 0 grio tc qdisc change dev eth0 root gred limit 60KB min 15KB max 30KB burst 30 avpkt 576 probability 0.01 DP 0 prio 1 tc qdisc change dev eth0 root gred limit 60KB min 15KB max 30KB burst 30 avpkt 576 probability 0.02 DP 1 prio 2 tc qdisc change dev eth0 root gred limit 60KB min 15KB max 30KB burst 30 avpkt 576 probability 0.03 DP 2 prio 3 tc qdisc show dev eth0 Actual results: qdisc gred 800d: root refcnt 2 DP:0 (prio 8) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 21 Scell_log 12 DP:1 (prio 8) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 20 Scell_log 12 DP:2 (prio 8) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 19 Scell_log 12 Expected results: qdisc gred 800d: root refcnt 2 DP:0 (prio 1) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 21 Scell_log 12 DP:1 (prio 2) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 20 Scell_log 12 DP:2 (prio 3) Average Queue 0b Measured Queue 0b Packet drops: 0 (forced 0 early 0) Packet totals: 0 (bytes 0) ewma 3 Plog 19 Scell_log 12 Additional info:
I cannot reproduce this in f15, iproute-2.6.38.1-4.fc15.x86_64 Now just to find the fix and backport it to f13 and possibly f14...
(In reply to comment #1) > I cannot reproduce this in f15, iproute-2.6.38.1-4.fc15.x86_64 > Now just to find the fix and backport it to f13 and possibly f14... It might be this: diff iproute2-2.6.33/tc/q_gred.c iproute2-2.6.38/tc/q_gred.c 54c54 < struct tc_gred_sopt opt; --- > struct tc_gred_sopt opt = { 0 }; 86c86 < opt.grio=1; --- > opt.grio = 1; 103d102 < memset(&opt, 0, sizeof(struct tc_gred_sopt));
Didn't work for me. Might be a kernel problem...
CORRECTION: That did work. I compiled the unpatched version by mistake. Bug solved. Thanks
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
