I'd like to see a little more smoke testing before 17:03:01 uploading. 17:03:01 We've also began providing the 12.10 kernel for 12.04. We welcome any 17:03:01 early adopters to please install, test, and let us know your feedback. 17:03:01 It is available from the following PPA: 17:03:03 https://launchpad.net/~ubuntu-x-swat/+archive/q-lts-backport 17:03:05 Important upcoming dates: 17:03:07 * Thurs Jun 28 - Alpha 2 (~2 weeks) 17:03:11 .. 17:03:24 [TOPIC] Status: Stable, Security, and Bugfix Kernel Updates - Precise/Oneiric/Natty/Lucid/Hardy (bjf/herton/henrix) 17:03:29 Here is the status for the main kernels, until today (June 05): 17:03:29 17:03:30 * Hardy - 2.6.24-31.102 - Being prepared; 2 CVEs 17:03:31 * Lucid - 2.6.32-41.91 - Being prepared; 2 CVEs 17:03:32 * Natty - 2.6.38-15.61 - Being prepared; 3 CVEs 17:03:33 * Oneiric - 3.0.0-22.36 - Being prepared; 1 upstream stable release (approx. 60 commits), 1 CVE 17:03:34 * Precise - 3.2.0-26.41 - Being prepared; 1 upstream stable release (approx. 137 commits) 17:03:35 17:03:36 Current opened tracking bugs details: 17:03:37 * http://people.canonical.com/~kernel/reports/kernel-sru-workflow.html 17:03:38 17:03:39 For SRUs, SRU report is a good source of information: 17:03:40 * http://people.canonical.com/~kernel/reports/sru-report.html 17:03:41 17:03:42 Future stable cadence cycles: 17:03:43 * https://wiki.ubuntu.com/QuantalQuetzal/ReleaseInterlock 17:03:44 17:03:45 .. 17:03:52 [TOPIC] Status: CVE's (sconklin) 17:03:56 == 2012-06-12 (weekly) == 17:03:56 Currently we have 89 CVEs on our radar, with 0 new CVEs added this week. 17:03:57 See the CVE matrix for the current list: 17:03:57 [LINK] http://people.canonical.com/~kernel/cve/pkg/ALL-linux.html 17:03:57 There is no change in the backlog this week: 17:03:57 [LINK] http://people.canonical.com/~kernel/status/cve-metrics.txt 17:03:59 [LINK] http://people.canonical.com/~kernel/cve/pkg/CVE-linux.txt 17:04:01 .. 17:04:13 [TOPIC] Open Discussion or Questions? Raise your hand to be recognized (o/) 17:04:17 o/ 17:04:23 kamal, go 17:04:24 o/ 17:04:31 I've recently been working with the upstream Bufferbloat group: http://www.bufferbloat.net ... 17:04:32 They have implemented new network scheduler algorithms designed to address the performance drag induced by large unmanaged network buffers. The new stuff ("fq_codel" and "codel") just landed in linux 3.5. 17:04:40 A good article about the bufferbloat problem and the new scheduling algo's is here: http://queue.acm.org/detail.cfm?id=2209336 17:04:40 The result is *very* impressive: I see a 30X reduction in ping latency on a fully saturated 10Mbps network, just by switching on the new fq_codel scheduler. 17:04:49 For an interactive ssh session over that same saturated 10Mbps network, fq_codel totally eliminates the laggy keyboard response -- it feels like there's no other network traffic at all! 17:04:49 I have produced a Bufferbloat PPA to allow us to experiment with this stuff now in Precise and Quantal: 17:04:58 https://launchpad.net/~kamalmostafa/+archive/bufferbloat 17:04:58 The PPA includes a "quantal-3.4-plus-bufferbloat" kernel for precise and quantal. (The new schedulers won't work on pre-3.3 kernels). The PPA page links to a quick how-to-smoke-test-it guide and more info. 17:05:07 The Bufferbloat group is eager for testing and feedback and general eyeball time from the Ubuntu kernel team and the Ubuntu community. Their channel is #bufferbloat on freenode. 17:05:07 Please give my PPA a whirl, and get a taste of the new cutting-edge network goodness. Any questions about it -- I'll at least know who to direct you to, so feel free to ask me. 17:05:08 .. 17:05:45 BenC, go 17:05:48 I had this on the meeting agenda, but don't see it above. 17:05:52 Trying to get some feedback for the patches I sent to kernel-team@, hoping to get it merged for next kernel upload 17:05:57 Re: PowerPC e500mc 17:06:17 .. 17:07:00 BenC, i think that are being reviewed at the moment arn't they ? 17:07:10 If so, I'm unaware :) 17:08:28 Also, if there are any suggestions on changes to my workflow for getting powerpc stuff merged, let me know 17:08:32 we are looking at them and seeing if they scare us or not 17:09:01 bjf: The only scary one(s) are the mdio phy changes, but I have tested them extensively on non-ppc 17:09:13 BenC: just got back after 5 days off. they are on my todo list. 17:09:33 Everything else is either nop or segmented on non-ppc 17:09:35 tgardner: thanks 17:09:52 a lot of the patches are sauce, are those also heading upstream ? 17:10:00 All of them have been pushed upstream 17:10:03 2 have been accepted 17:10:07 BenC: I should have some comments by tomorrow. got a huge pile of email to deal with... 17:10:11 Oh wait, not the SAUCE, not yet 17:10:36 freescale had 360+ patches last year, so they've done a lot to get this merged upstream 17:10:50 These are the last few, and are being dealt with in the coming months 17:11:42 tgardner: ok, please email, ping me if any questions come up… 17:11:51 will do 17:11:52 .. 17:11:55 .. 17:12:11 Anything else for open discussion? 17:12:39 Thanks everyone 17:12:39 #endmeeting
