20110726 Meeting Agenda


ARM Status

  • Oneiric/ti-omap4: finally pushed out the first oneiric 3.0 + TI BSP kernel (3.0.0-1200.2), and there’s already a BSP update in the pipe.
  • Oneiric/tegra: forward ported/triaged around ~600 patches from 2.6.38 to 3.0 – basically video/ and arch/arm/mach-tegra/, plus some glue functions here and there. The kernel doesn’t compile yet.

Blueprints: Oneiric Delta Review

apw, lag, rsalveti: you have work items to review your set of Ubuntu patches. I’ve pushed these out to Alpha-3 for you. Please take a moment to review when you have a chance. See https://wiki.ubuntu.com/KernelTeam/Specs/KernelOneiricUbuntuDeltaReview for your specific set of patches. Note, these are the only remaining work items for this blueprint.


Status: General Oneiric

Last week we uploaded the 3.0.0-7.8 kernel. This most notably enabled overlayfs as well as rebased to upstream v3.0 final. Alpha-3 is next Thurs, Aug 4th. I intend to upload our final Alpha-3 this Friday, July 29th. If there are any patches that need to land for Alpha-3, get them sent to the kt-ml asap.


Status: CVE’s

CVE Metrics

After hitting 0 CVEs open on all branches but Hardy at the start of the week we have seen, one CVE has resurface and 8 new ones have been added. Luckily a large number of the new CVEs are already fixed in Lucid and later.

ARM Status

Kernel development: nothing to report.
Oneiric/ti-omap4: got a new BSP drop from agreen, rebased on top of rc7 and rolled out a new kernel. People in the arm team are testing it and so far (besides an audio bug that looks like a pulseaudio issue) it looks good. A kernel package is available here: http://people.canonical.com/~ppisati/ti-omap4-next/ while the source code is available on ppisati@zinc:oneiric-git/ti-omap4-next.

Blueprints: Oneiric Server Requirements

No change here. As the remains items are pretty much depending on outcome of something else and either fall off completely or get pushed out as we go, I am not sure it really needs to be on the agenda anymore. Would people mind dropping it?

This will be dropped from the weekly agenda.


Status: General Oneiric

Nothing very exciting this past week. I plan to do an upload today or tomorrow to get patches on master-next released. Alpha-3 is Thurs Aug 4th. I intend to upload our final Alpha-3 kernel next Friday July 29th. If there are any patches that need to land for Alpha-3, get them sent to the kt-ml asap.

Status of kernels

Several regressions have been reported in Natty after release last week,
None of these were detected in QA, Certification, or -proposed testing.


Hardy

  • Hardy Tracking Bug
  • A new kernel is in -proposed. Since this kernel contains only CVE fixes, there is no verification to be done, and it is ready for QA


Lucid

  • Previous kernel has been released, but a new one has not been prepared yet


Maverick

  • Maverick Tracking Bug
  • Kernel in -proposed from the last cycle is awaiting certification and regression testing.


Natty

  • Natty Tracking Bug
  • Previous kernel has been released, and a new one is in -proposed.
  • Verification has begun for this kernel, and will continue through next week.

I was out last week, but we’ve recently uploaded the 3.0.0-5.6 Oneiric kernel. It’s based on the latest v3.0-rc7 mainline kernel. We’ve also converged upon using a 3 digit version scheme for our Ubuntu kernel version, ie. 3.0.0 rather than 3.0

Natty

[[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/802464]]

Kernel in -proposed is ready to be published to -updates and -security

There was a failure of this kernel in QA due to a kernel option that was not correctly set.
This option had been changed to work around some problems in the ec2 environment.
Those issues have been resolved and the option can be returned to the former state.
This was not serious enough of an issue to prevent releasing this kernel.

ARM Status

Kernel development: usual CVE fixes across different branches.
Oneiric/ti-omap4: we reached an agreement with agreen/linaro to get the TI BSP on top of a vanilla kernel, as a result a new oneiric/master-next-based kernel is in the work – see git://kernel.ubuntu.com/ppisati/ubuntu-oneiric.git ti-omap4-next. Still a WIP, kernel panics on boot ATM, do not use.

  • seccomp in progress

Status: Development Kernel Team

Overall we are progressing well, the kernel is stabalising nicely and regressions and bugs seem tractable at this time. We have a number of outstanding tasks for oneiric-alpha-2 which likely will slip further, most are upstreaming tasks and as such not release critical.

Development kernels – Oneiric

The oneiric kernel is currently at 3.0-3.4 which is based on 3.0-rc5 from mainline. As well as the mainline kernel update this kernel also dropped the ARM versatile flavour which is deprecated.

We are in milestone freeze for oneiric-alpha-2 which releases this upcoming thursday. We expect to upload an upstream 3.0-rc6 kernel as soon as the freeze lifts.

Status: Stable Kernel Team

The commits responsible for the known regressions in Lucid and Natty were identified, their kernel packages are not being held anymore. Everything is progressing in the SRU workflow process.

Status now is:

  • Hardy: kernel in -proposed is in verification. One bug remaining to be verified.
  • Lucid: Currently in verification. In the end of verification phase it should progress to qa/regression testing and for security-signoff.
  • Maverick: Currently in verification. No regressions so far. Two bugs remaining to be verified.
  • Natty: Passed verification, security-signoff done. Waiting for regression-testing to start, and going through certification testing.
  • Current SRU status is here:
