Eric Desrochers (slashd) wrote : [sos41] networking plugin may invoke devlink module when not loaded depending on how the kernel is configure

[Impact]

We don't want sosreport to triger kernel module to load.
This is causing Bionic autopkgtest to fails on 4.15 kernel.

simple.sh will report a failure:
"new kernel modules loaded during execution"

[Test case]

On a 4.15 kernel (Bionic)

root@srv:~# lsmod | grep -i devlink
root@srv:~# sos report -o networking
root@srv:~# lsmod | grep -i devlink
devlink 45056 0

Not reproducible on Bionic w/ 5.4 kernel for instance

Reason:
config-4.15.0-140-generic:CONFIG_MAY_USE_DEVLINK=m
config-5.4.0-70-generic:CONFIG_NET_DEVLINK=y

CONFIG_MAY_USE_DEVLINK:
Drivers using the devlink infrastructure should have a dependency on MAY_USE_DEVLINK to ensure they do not cause link errors when devlink is a loadable module and the driver using it is built-in.
