Right -- systemd have just-now agreed to set the change in their upstream systemd sysctl files :- https://github.com/systemd/systemd/commit/6f130e85c76cfc2c58ba31f90d2ac3800866c1dd
I notice, however, that ubuntu's systemd pkg 'strips most those settings out', in 18.04 currently only carrying the 18.04 fq_codel switch-on in their sysctl.d.... I think, given what has been said, I would like to propose that I :- * Make a suggested text for a 10-network-bufferbloat.conf here in procps in 18.10 (hopefully-onwards, including suitable references/comments about BBR (which should be there but commented/not- enabled yet unless we are sure its' been fixed to respond to ECN notifications.). This text shall explain clearly these are deliberately being tested into 18.10 and where to report bugs. * Look at what ubuntu's systemd package towards 18.10 is importing in sysctl.d -- and likely suggest ubuntu 'taken out' entirely so procps is the 'one' location for these settings (i.e. no duplicate setting of qdisc=fq_codel in 2 different places). Some will want to boot ubuntu with OpenRC or upstart for whatever reasons and consistent-behaviour would be helpful... * Ask in the BBR community about tcp_congestion_control goings-on there, when they are ready for ECN-compatible BBR wider-deployment. * Then, as/when seems appropriate, suggest changes into upstream-debian and upstream-kernel on the defaults. @rbalint -- what do you think on this plan for the interim? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773157 Title: procps outdated network options, old syncookies, new ecn update please.
