The commit "s390/qeth: fix false reporting of VNIC CHAR config failure"
is in focal master-next and tagged with:
Ubuntu-5.4-5.4.0-13.16
Ubuntu-5.4-5.4.0-14.17
We have currently the following kernels in focal:
linux-generic | 5.4.0.12.15 | focal | s390x
linux-generic | 5.4.0.13.16 | focal-proposed | s390x
Hence the above patch is not yet in 5.4.0.12.15 that's currently in the
release pocket, but already in proposed. Hence changing the focal status
here to Fix Committed.
** Changed in: linux (Ubuntu Focal)
Status: Triaged => Fix Committed
** Changed in: ubuntu-z-systems
Status: In Progress => Fix Committed

Bug description:
SRU Justification:
------------------
[Impact]
* For devices that don't support the 'INVISIBLE' characteristic (ie.
OSA), the resulting IO failure raises the noisy error message
"Configuring the VNIC characteristics failed"
* The INVISIBLE characteristic unconditionally gets switched off,
which is reverted with this patch.
* For Internal Queued Direct communication (IQD) 'INVISIBLE' is off by
default.
* Hence the INVISIBLE characteristic case is unnecessary.
[Fix]
* 68c57bfd52836e31bff33e5e1fc64029749d2c35 68c57bf "s390/qeth: fix
false reporting of VNIC CHAR config failure"
* Upstream accepted with v5.5-rc5, but backport for 4.19-stable and
5.4-stable here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-
queue.git
[Test Case]
* Configure an IBM z15 for LinuxONE III machine with at least one OSA
adapter.
* Check dmsg for message "Configuring the VNIC characteristics failed"
while setting an OSA device online.
[Regression Potential]
* The regression potential is low, since the patch is limited to a
single line
* again limited to the s390x architecture and once again limited to
the qeth network driver
* and on z15 hardware only.
[Other Info]
* This bug was identified at IBM while testing and is now rolled out
to several different kernels.
* Once the patch got applied to the Ubuntu kernel(s) and a
verification is required,
* this needs to be done by IBM, since Canonical doesn't have the
needed machine generation.
