Feature buffer full in precise with LTS kernel

Marking confirmed as both rtg and I have seen it.

The kernel is the one from https://launchpad.net/~ubuntu-x-swat/+archive/s-lts-backport

I verified that this patch applied to 2.7.102-0ubuntu3.8 allows lxc to be installed when the host is has booted a Saucy LTS kernel (v3.11.0).

P.S. The patch in #3 is a backport from apparmor 2.8.0-0ubuntu24 (0041-parser-fix-flags.patch)

Tim, I have finished validation on bug #987578 which had held up a previous SRU of apparmor to precise.

Tim, the apparmor 2.7.102-0ubuntu3.8 package will not be pushed through SRU quickly as the 12.04.3 update is taking precedence. Adam Conrad suggested bundling this patch together on top of the apparmor package in -proposed and pushing on Monday:

Wed 21 15:46:50 < infinity> sarnold: Given a point release is in progress pretty much as we speak, releasing that today is a no-go anyway.
Wed 21 15:47:25 < infinity> sarnold: So, you could just upload on top of that for the other bug as well, verify the lot, and we can push it all in on, say, Monday.

Thanks

debdiff looks good. ACK. I'm testing locally now and report back and upload in a bit.

Uploaded 2.7.102-0ubuntu3.9 to precise-proposed. Local testing shows all patches applied, no new compiler warnings/errors, upgrades fine and passes QRT.

Hello Serge, or anyone else affected,

I tested apparmor 2.7.102-0ubuntu3.9 on both 12.04 LTS i386 and amd64 with the above PPA kernel (known to overflow the small buffer). In both cases, the updated package allowed AppArmor profiles to be loaded and thus allowed lxc package install to finish.

Thanks

This bug was fixed in the package apparmor - 2.7.102-0ubuntu3.9
