[Bug 2042885] [NEW] [UBUNTU 22.04] Running smartctl on NVME hit segmentation fault

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Andreas Hasenack (ahasenack):

[ Impact ]

 * smartmontools crash when it is reading NVME error log on a big-endian
system.

[ Test Plan ]

 * Prepare a big-endian system (like an Ubuntu on s390y)
   and attach an NVME drive to it.
   This nvme drive could have error logs, but it's ok if it doesn't.

 * Run `sudo smartctl -i -a /dev/nvme0` against NVME drive to get SMART data
   and hit Segmentation fault.

 * Run this command again with patched smartctl will show SMART data and error
   logs normally

[ Where problems could occur ]

 * The process of reading error log page from NVME device on big-endian
system.

[ Other Info ]

 * Ubuntu 'noble' is not affected, since it incl. v7.4 which incl. the
fix already.

 * We skip 23.04, since it is too close to end of life (in about 2 weeks
from now).
