[Bug 2092053] Re: openafs-modules-dkms FTBS in Noble with linux-6.11-hwe kernel

[Timo Aaltonen]

Hello Massimiliano, or anyone else affected,

Accepted openafs into noble-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/openafs/1.8.10-2.1ubuntu3.3 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: openafs (Ubuntu Noble)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-noble

  [ Test case ]

  Install the latest linux-6.11 kernel on Noble:

  $ sudo add-apt-repository ppa:canonical-kernel-team/ppa
  $ sudo apt update
  $ sudo apt install linux-image-6.11.0-12-generic \
                     linux-modules-6.11.0-12-generic \
                     linux-modules-extra-6.11.0-12-generic \
                     linux-headers-6.11.0-12-generic

  Install openafs-modules-dkms:

  $ sudo apt install openafs-modules-dkms

  Load the module:

  $ sudo modprobe openafs

  The same procedure should be repeated on linux-6.8 to test for
  possible regressions.

  [ Fix ]

  Patch the code to properly support the new linux 6.11 ABI.

  [ Regression potential ]

  We may experience regressions in systems that are using openafs with
  the new 6.11 kernel.
