ARM Status

P/omap4: a new kernel version (1405.7) was released, with improved PM support and fixes for the usb subsystem (CMA revert).
P/master: problems with mmc were due to twl4030’s GPIO lines being inactive at boot time since support was factored out in a kernel module; recompiling it in the main kernel made omap3 boards boot off the mmc again (12.20).
SRU: new kernels were released for every supported arch/release.

Release Metrics and Incoming Bugs

Milestone Targeted Work Items

I’ve pushed out any open work items from Alpha-2 to Beta-1.
Additionally, some work items have come to my attention but I’m unaware
of anyone from our team actually working on them:
[canonical-kernel-team] investigate large xattr support patch from Ted T’so in ext4: TODO
[canonical-kernel-team] potentially help push large xattr support to ext4: TODO

Did anyone attend that session at UDS and commit us to those work items?
I suspect these may just get postponed. They were for the cluster filesystem, which is used in openstack.
There will be a follow up and see if more details can be found.
[canonical-kernel-team] provide a kernel with uuid support in the internal initrd for measuring

I vaguely recall there were discussions regarding this work item at the rally, but I’m unaware of what the outcome was?

The foundations WIs were all postponed/blocked yesterday, including the above work item?
A test of with/without initrd can be done, but that wont tell anything about with/with minimal initrd in kernel

slangasek set his items to blocked.

ogra_, but don’t we have an option to generate a minimal initrd now ?

ogra can easily provide you with data tomorrow if that helps anyone

Those would be interesting numbers.

Minimal means the in-kernel initrd just containing teh blkid command as we had discussed

Though i think slangasek would even like to see that done in-kernel with a patch (which i think you already said is to intrusive)

A plan should be discussed for this feature offline, we are clearly confused on who is doing what when in which order

tgardner: FSVO “minimal” that always includes udev and sundry other utilities

slangasek, not necessarily, thats why we have devtmpfs, no ?

slangasek, I guess I was referring to the “tailored” initrd so taht we could see if there was _any_ time differences

there is no support for generating any genuinely minimal initramfs out of initramfs-tools

right, it will always be bloated and at least contain both libc’s
we’ll discuss it offline ..

Everyone OK with moving on?

Blueprint: hardware-p-kernel-power-management

nothing to report this week

Status: Precise Development Kernel

Last week we rebased to v3.2.2 and uploaded. There is a potential
regression in v3.2.2 that I’m concerned about, bug 923512. jsalisbury
is working with the bug reporters and has a test kernel with the
offending patch reverted. If anyone else has hw which uses the ath9k
driver, it would be nice if you could test. I’d consider this would
warrent an upload to fix before the milestone which is in 2 days, Thurs

Status: CVE’s

Currently open CVEs for each supported branch:

Note that the table has a new column this week, the “Defd” column
represents the number of CVEs which have been referred back to security for
resoution, either for lack of a fix or if the fix is not clearly complete.

Nine new CVEs were added this week, of which about 6 have been resolved.
We have also finally dropped lucid/mvl-dove from the table above.
