** Description changed:
[Impact]
* The openafs DKMS module fails to build on 5.0 kernels due to changes
in the kernel API between 4.15 and 5.0. This affects the Bionic
HWE{-edge} kernels which are based on 5.0.
[Test Case]
* Install the `openafs` dkms modules package (sudo apt install openafs-
modules-dkms)
Expected result: the package installs without any build-time errors, and
the module is listed when `sudo dkms status` is ran.
Actual result: the package installation fails because the openafs dkms
module fails to build with compilation errors
[Testing]
These instructions were carried out in an amd64 Bionic virtual machine
with the 4.15 Bionic kernel and the 5.0 Bionic HWE kernel.
* Install the 5.0 kernel (sudo apt update; sudo apt install
linux-image-generic-hwe-18.04)
- * Install the ubuntu-dev-tools package (sudo apt install ubuntu-dev-tools)
- * Download the openafs package (pull-lp-source openafs bionic)
- * In the openafs directory, run "quilt pop -a"
- * Apply the .debdiff in comment #3 (patch -p1 < ../path-to-file.debdiff)
- * Apply all patches (quilt push -a)
- * Build the package (debuild -b -uc -us)
- * Install the `openafs-modules-dkms_1.8.0~pre5-1ubuntu1.1_all.deb` produced
from the previous step.
+ * Install `openafs-modules-dkms` from -proposed
* Confirm the package installs correctly on 4.15 and 5.0 kernels (it should
install for both). Run "sudo dkms status" and ensure it's listed there.
If it doesn't install for both kernels, you can prompt it to install for
a specific kernel like this: "sudo dkms install openafs/1.8.0pre5 -k
4.15.0-55-generic/x86_64
[Regression Potential]
Low. These changes use preprocessor define macros that are deduced at
configuration time to tell the package to act "normal" if a given
feature exists or doesn't exist.
