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

[Łukasz Zemczak]

Okay, this looks okay-ish enough to sponsor, so I will upload it to the jammy queue. However, there's a few things:
1) This is only the debdiff for jammy, and I see mantic also doesn't have this change. Should we also upload this to mantic? We have this rule to make sure every change is available in the newer series as well as the older ones.
2) The test case should be made a bit more specific. Like, this only reproduces on a big endian system, right? Can you detail a bit more on where to test it then etc.?

  [ Impact ]

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

  [ Test Plan ]

   * 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
