Release Metrics and Incoming Bugs

Release metrics and incoming bug data can be reviewed at the following link:

  • http://people.canonical.com/~kernel/reports/kt-meeting.txt


Status: Precise Development Kernel

The Precise kernel is currently frozen and we are gearing up for release
this Thurs Apr 24. Release candidate images are already available. We
have prepared a day-0 kernel upload that contains a few bug fixes which
we would like to have immediately available to users. We will upload the
day-0 kernel to precise-proposed today and it will be pocket copied to
precise-updates. I then intend to hand the maintenance repsonibilities
of the Precise kernel over to the Stable Maintenance Kernel Team on
Friday.
Important upcoming dates:

  • Thurs Apr 26 – Final Release (2 days! \o/)


Status: CVE’s

Currently we have 76 CVEs on our radar, with 5 new CVEs added this week.
See the CVE matrix for the current list:

  • http://people.canonical.com/~kernel/cve/pkg/ALL-linux.html

    Overall the backlog has increased slightly slightly this week:

  • http://people.canonical.com/~kernel/status/cve-metrics.txt

  • http://people.canonical.com/~kernel/cve/pkg/CVE-linux.txt

    This week sees the vestages of maverick dropping from the tracker.


Status: Stable, Security, and Bugfix Kernel Updates – Oneiric/Natty/Maverick/Lucid/Hardy

Here is the status for the main kernels, until today (Apr. 24):

  • Hardy – 2.6.24-31.101 – Nothing last cycle
  • Lucid – 2.6.32-41.88 – In updates
  • Natty – 2.6.38-14.58 – In updates
  • Oneiric – 3.0.0-19.32 – Regression testing

    Current opened tracking bugs details:

  • http://people.canonical.com/~kernel/reports/kernel-sru-workflow.html

    For SRUs, SRU report is a good source of information:

  • http://people.canonical.com/~kernel/reports/sru-report.html

    Future stable cadence cycles:

  • https://wiki.ubuntu.com/PrecisePangolin/ReleaseInterlock

    Due to this being releas week and people get testy when we upload
    a barrage of SRU kernels, we are starting the next cadence cycle
    next week. This also works out conveniently making UDS week a
    bug verification week.

Status: Precise Development Kernel

The Precise kernel is currently frozen and release candidate images are
set to be spun this Thurs Apr 19. Final release is almost 1 week away
on Thurs Apr 26. We have started queuing patches for the first kernel
SRU. This includes patches from the most recent v3.2.15 upstream stable
release. Should an additional upload be required before final release,
we will try to include a few bug fixes which have been queued. Please
note that at this point in time, all patches are subject to our SRU
policy and uploads will only be granted at the discretion of the release
team.

Important upcoming dates:

  • Thurs Apr 19 – Release Candidate (~1 day)
  • Thurs Apr 26 – Final Release (~1 week)


Status: CVE’s

Status: Stable, Security, and Bugfix Kernel Updates – Oneiric/Natty/Maverick/Lucid/Hardy

Here is the status for the main kernels, until today (Apr. 10):

Oneiric has been somewhat problematic. We ran into a couple of very bad regressions
that were pretty quickly identified. Our policy is to “revert aggressively” however
our number one rule is to “Use our best judgement and do the right thing”. In this
case we are also running into the end of the Precise development cycle when testing
resources (human) are scarce. After discussing this with a number of people we have
decided to fix these known regressions and also pull in the stable release that was
sitting on master-next and crank that out. The cycle will be extended with regression
testing happening the week of May 1st.

  • Hardy – 2.6.24-31.101 – Nothing this cycle
  • Lucid – 2.6.32-41.88 – Verification; 52 commits in total.
  • Maverick – 2.6.35-32.68 – Ready for -updates; NOTE: THIS IS THE LAST MAVERICK KERNEL!
  • Natty – 2.6.38-14.58 – Ready for -updates; 12 commits in total. Mostly eCryptfs and KVM.
  • Oneiric – 3.0.0-19.32 – Verification;

ARM Status

P/omap4: mainly config changes trying to mimic master/generic config as much as possible. The dss/video issue (lp963512) found in the previous rebase is still unresolved (waiting for a new panda board since my own broke down exactly the day after the issue came up) – for the time being (kernel freeze) we are gonna stay with 3.2.0-1411.14 as it is good and no one complained about it, but as soon as i get the new board, it’ll be a
lp971091 (“Pandaboard ES freezes with the default CPU scaling governor ondemand”): i’m investigating this one with the reporter (sending debug kernels&c).

Status: Precise Development Kernel

Kernel Freeze is this Thurs Apr 5. I’ve already began prepping our
final upload prior to freeze and plan to upload after the meeting. If
they are any patches which need to land, let us know immediately. After
Kernel Freeze, all patches are subject to our SRU policy and uploads
will only be granted at the discression of the release team.
