[Launchpad Bug Tracker <1838555@xxxxxxxxxxxxxxxxxx>]

[Impact]

This was discovered at a customer site and affects all of their Bionic
installs that have Micron NVMe drives.

The version of nvme-cli present in Ubuntu 18.04 Bionic Beaver (1.5-1)
does not include support to manage updating the firmware on Micron NVMe
drives. The missing support also means that the customer cannot format
their block size to 4k, as needed by Ceph.

Version 1.6-1 and later versions do include this support, and can be
used by rebuilding the package from upstream source as a static binary.
This is not ideal, but a workaround.

[Test Case]

Install nvme-cli from Bionic, and attempt to update firmware for any
Micron NVMe drive, using a command similar to the below. It will fail,
as the drive is not supported.

$ nvme micron select-download /dev/<nvme_device>n1 --fw
./Micron_9200_FW-101008S0.tar --select=ALL

With the upstream commit patched into place, we can verify the
subcommands function with:

$ nvme micron

This will display the help screen and a list of supported commands.

$ nvme micron select-download

This will show the help page for firmware updating, and required
arguments. Running again with the arguments from the first example will
update the firmware on the drives successfully.

You can find a test package for Bionic here:

[Regression Potential]

The opportunity for regression is low. The Micron support is implemented
as a plugin for the application and the changes are more or less
standalone. The code paths can only be accessed via "nvme micron"
subcommands.

If a regression happens, then users should refrain from running "nvme
micron" commands while the package is fixed.

[Other Info]

The commit that adds support for Micron drives is:

commit 0124daa3331602365d009a9e8229454c41931c07

Subject: Add support for Micron plugin

https://github.com/linux-nvme/nvme-
cli/commit/0124daa3331602365d009a9e8229454c41931c07

This commit landed in version 1.6, and is present in the following
distros:

$ rmadison nvme-cli -a amd64
nvme-cli | 1.5-1 | bionic/universe | amd64
nvme-cli | 1.6-1 | cosmic/universe | amd64
nvme-cli | 1.7-1 | disco/universe  | amd64
nvme-cli | 1.7-1 | eoan/universe   | amd64

There is a minor backport required for the commit into version 1.5, and
that is in the Makefile. Some other plugins which are not currently
present are in the patch, and needed to be removed from the OBJS line.
