Status: Raring Development Kernel

We are 2 days from 13.04′s release. All kernel patches submitted must
adhere to our SRU policy. Only critical bug fixes necessary for the
13.04 release will warrant an upload at this time. There are currently
no plans for a 0-day SRU kernel either.

Important upcoming dates:

  • Thurs Apr 25 – Ubuntu 13.04 Final (2 days)


Status: CVE’s

== 2013-04-23 (weekly) ==
Currently we have 81 CVEs on our radar, with 18 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 decreased slightly this week:

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


Status: Stable, Security, and Bugfix Kernel Updates – Quantal/Precise/Oneiric/Lucid/Hardy

  • Lucid – In Verification; (14 commits)
  • Precise – In Verification; 2 upstream releases; (170 commits)
  • Quantal – In Verification; 2 upstream releases; (225 commits)
    Precise and Quantal had multiple regressions during verification.
    One regression has been isolated to an i915 patch which has been reverted
    The other is almost completely bisected.
    When complete, Precise and Quantal will be respun.

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

Open Discussion or Questions? Raise your hand to be recognized

There was a question about what’s going on the arm side.
The question was rather open ended, so further discussion was moved to #ubuntu-kernel.
The following patch was also discussed: http://cgit.freedesktop.org/~mlankhorst/linux/commit/?id=ae7b687c2a57ec50a9d3dde7b0a80a262fdc8c8
It was requested that a bug is opened, and a SRU request can be submitted.

ARM Status

R/master: found a fix for lp1168039 (“highbank: network corruption”) and
lp1166956 (“[highbank] Oops: PC is at pl330_irq_handler+0x21c/0x3b0 [pl330]“),
still working on the reboot issue on highbank (but i tracked it down to a pl310
errata).
R/nexus4: sent a config diff that made our nexus4 kernel work with the phablet
image.
ppisati, will the highbank fixes make it today ?
rtg: nope, i wanted to send them all together when i’ve fixed the reboot issue too
tomorrow is last upload before release

branch to the latest upstream v3.9-rc5.
