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

[Andreas Hasenack]

This was accepted for jammy so that the verification there can start,
but an upload for mantic is still needed before anything can be released
to updates.

Title:
  [UBUNTU 22.04] Running smartctl on NVME hit segmentation fault

Status in Ubuntu on IBM z Systems:
  In Progress
Status in smartmontools package in Ubuntu:
  Fix Released
Status in smartmontools source package in Jammy:
  Fix Committed
Status in smartmontools source package in Lunar:
  Won't Fix
Status in smartmontools source package in Mantic:
  In Progress

Bug description:
  [ 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).
