Blueprints: Natty Bug Handling

Nothing to report.

Blueprints: Kernel Configuration Review

PV on HVM support (XEN_PCI_PLATFORMDEV) testing is still pending for natty-alpha-2. The only other remaining action here currently is to report on the final config at beta time, this is waiting on the final kernel version.

Blueprints: Enhancements to the firmware test suite

Nothing to report

Blueprints: Handling of Deviations from Standard Kernels

I got a little farther with the tool by now. Detection seems to work. The output needs a bit of polish still.

Blueprints: Review of the Stable Maintenance Process (sconklin / bjf)

The new cadence is working pretty well, but we continue to address issues as they arise. These mostly have to do with insuring adequate communication between various teams. I'm concerned that thw two-week cycle may not leave us enough time for exceptions and tools development, and we will be discussing this at the platform rally next week. We're planning to begin a cycle by uploading new kernels this Friday, which will put us in verification phase during the rally.

Status: Cert. Team

We found this bug before the holidays: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/693042 and it wasn't being worked upon since then, but I have seen that now apw is on it.

That one is looking like it may be an issue with upstart, see comment #7.

I will try this week with the latest ISOs, although it seems it is still there.

Blueprints: Ubuntu Kernel Delta Review

15 of the 19 personal patch reviews are now done. All of the ubuntu drivers are now updated and reviewed. Some work remains on compcache which is now superceeded by zram in staging, but some userspace work is required to switch to it.

Blueprints: Kernel Version and Flavours

We are still working to determine how to provide omap3 kernels, testing is ongoing of a master based kernel.

Status: Ecryptfs

Prototype is in progress, but isn't up yet. It should be working in a day or two. I started messing with putting the long names in the header but switched to xattrs due to the factors detailed below.

  • Storing long names in meta data is problematic for hardlinks - this can be handled somewhat by either allowing a single longname or by allowing multiple longnames as space allows fail over to storing long names in header
  • long directory names - problematic. There is no header for directories
  • long symlink names - problematic.
  • require update of header (reencryption) on rename fail over to storing long names in xattrs
  • problematic for filesystems that don't support xattrs
  • leaks fact that long name is present unless all files are given longname xattr
  • requires update of xattr (reencryption) on rename

Combine current FNEK names and longnames requires encoding information to that a given name was long and stored differently, this leaks some information about the filename. This leak provides more information than the xattr on the file, in that it provides information on which dentry is long when a file has multiple names.

Status: Natty

The main distro kernel is now at 2.6.37-11.25 (v2.6.37-rc7 based). v2.6.37-rc8 has already released and we are expecting v2.6.37-final shortly, we are planning one more upload before the Rally.
