Description

For context, initial analysis, and test results, see Bug #16177.

Next steps:

  1. Verify that squashfs-tools 4.3-3.0tails4 does honor -mem consistently (I think I did already but let’s be sure).
  2. Find out why squashfs-tools 4.3-11 does not honor -mem consistently, e.g.:
    1. Try to reproduce with pristine 4.3-3 changes
    2. Try reverting the 4.3-3..4.3-11 changes
    3. Try applying the patchset collected by lynxis on top of 4.3-11
  3. Report the bug, ideally with a patch attached.

Mon 18 14:22 <@lamby> Looks like something that could be handled under FT.
Mon 18 14:23 <@lamby> If so, I'll file an issue in Redmine

This was fixed in:

 squashfs-tools (1:4.3-12) unstable; urgency=medium
 .
   [ Alexander Couzens <lynxis@fe80.eu> ]
   * Fix compressor initialization in frag_deflator() (closes: #923711).

I’m going to request an unblock for buster.

Resolving to match.

Woohoo!

> Resolving to match.

I think we’ll need to revert commit:6370ba62f331a6c715cbcdb625f4b9a5f7af13a4 in order to switch to this new, unblocked version (otherwise we’re stuck with a temporary workaround).
