Status: Quantal Development Kernel

With 12.10 scheduled to release this Thurs Oct 18, we do not foresee any
critical kernel bugs which would warrant an upload and require a respin
of images. All patches currently queued will be available in the first
kernel SRU following 12.10′s release. Some of these queued patches
include the v3.5.6 and v3.5.7 upstream stable patch sets as well as
additional misc bug fixes.
Important upcoming dates:

  • Thurs Oct 18 – 12.10 Final (2 days!)
  • UDS-R – Oct 29 – Nov 1


Status: CVE’s

Milestone Targeted Work Items

I am now the proud owner of all remaining work items. I’ll be sure to
close these out asap.
This item will be removed from our agenda for the remaining meetings this release.

Status: Quantal Development Kernel

We have received a freeze exception and are planning to upload the
3.5.0-18.28 today. This will provide critical bug fixes for the 12.10
release. The bugs include:

  • 1063061 “please backport support for EFI vars ) 1KB”
  • 1061599 “beagle: omap3: usb is dead”
  • 1021471 “clone() hang when creating new network namespace”
  • 1030233 “not have bluetooth usb 0489:e046 Foxconn / Hon Hai”
  • 717970 “After sleep, key presses get lost and trackpad is jittery”
    As a reminder, because we are in kernel freeze, all patches are subject
    to the SRU policy and only critical bug fixes will warrent an upload.
    Non critical bug fixes and changes will be targetted to the first
    Quantal SRU kernel. As usual, all kernels will also get uploaded to the
    q-lts-backport [1] PPA to help facilitate testing of the 12.10 kernel in
    12.04. We welcome anyone to please install, test, and let us know your
    feedback.

Open Discussion or Questions? Raise your hand to be recognized

dhillon-v10 would like to discuss his approach to module signing. dhillon-v10 was asked how his approach is different from david howell’s. The approach from dhillon-v10 is a hybrid between what chrome os does and what David Howell posted.

It was suggested that dhillon-v10 post his approach to the kernel team mailing list. That way it preserves the discussion and gives people in different time zones an ability to review it.
