Free software activities in January 2018

By Chris Lamb

Here is my monthly update covering what I have been doing in the free software world in January 2018 (previous month):


Reproducible builds


Whilst anyone can inspect the source code of free software for malicious flaws, most software is distributed pre-compiled to end users.

The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced — either maliciously or accidentally — during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised.

I have generously been awarded a grant from the Core Infrastructure Initiative to fund my work in this area.

This month I:



I also made the following changes to our tooling:

diffoscope

diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues.

  • New features:
    • Compare JSON files using the jsondiff module. (#888112)
    • Report differences in extended file attributes when comparing files. (#888401)
    • Show extended filesystem metadata when directly comparing two files not just when we specify two directories. (#888402)
    • Do some fuzzy parsing to detect JSON files not named .json. [...]
  • Bug fixes:
    • Return unknown if we can't parse the readelf version number for (eg.) FreeBSD. (#886963)
    • If the LLVM disassembler does not work, try the internal one. (#886736)
  • Misc:
    • Explicitly depend on e2fsprogs. (#887180)
    • Clarify Unidentified file log message as we did try and lookup via the comparators first. [...]

I also fixed an issue in the "trydiffoscope" command-line client that was preventing installation on non-Debian systems (#888882).


disorderfs

disorderfs is our FUSE-based filesystem that deliberately introduces non-determinism into directory system calls in order to flush out reproducibility issues.

  • Correct "explicitly" typo in disorderfs.1.txt. [...]
  • Bump Standards-Version to 4.1.3. [...]
  • Drop trailing whitespace in debian/control. [...]


Debian

My activities as the current Debian Project Leader are covered in my "Bits from the DPL" email to the debian-devel-announce mailing list.

In addition to this, I:

  • Published whydoesaptnotusehttps.com, an overview of why APT does not rely solely on SSL for validation of downloaded packages as I noticed it was being asked a lot on support forums.
  • Reported a number of issues for the mentors.debian.net review service.

Patches contributed

  • dput: Suggest --force if package has already been uploaded. (#886829)
  • linux: Add link to the Firmware page on the wiki to failed to load log messages. (#888405)
  • markdown: Make markdown exit with a non-zero exit code if cannot open input file. (#886032)
  • spectre-meltdown-checker: Return a sensible exit code. (#887077)

Debian LTS


This month I have been paid to work 18 hours on Debian Long Term Support (LTS). In that time I did the following:

  • Initial draft of a script to automatically detect when CVEs should be assigned to multiple source packages in the case of legacy renames, duplicates or embedded code copies.
  • Issued DLA 1228-1 for the poppler PDF library to fix an overflow vulnerability.
  • Issued DLA 1229-1 for imagemagick correcting two potential denial-of-service attacks.
  • Issued DLA 1233-1 for gifsicle — a command-line tool for manipulating GIF images — to fix a use-after-free vulnerability.
  • Issued DLA 1234-1 to fix multiple integer overflows in the GTK gdk-pixbuf graphics library.
  • Issued DLA 1247-1 for rsync, fixing a command-injection vulnerability.
  • Issued DLA 1248-1 for libgd2 to prevent a potential infinite loop caused by signedness confusion.
  • Issued DLA 1249-1 for smarty3 fixing an arbitrary code execution vulnerability.
  • "Frontdesk" duties, triaging CVEs, etc.

Uploads

  • adminer (4.5.0-1) — New upstream release.
  • bfs (1.2-1) — New upstream release.
  • dbus-cpp (5.0.0+18.04.20171031-1) — Initial upload to Debian.
  • installation-birthday (7) — Add e2fsprogfs to Depends so it can drop Essential: yes. (#887275
  • process-cpp:
    • 3.0.1-1 — Initial upload to Debian.
    • 3.0.1-2 — Fix FTBFS due to symbol versioning.
  • python-django (1:1.11.9-1 & 2:2.0.1-1) — New upstream releases.
  • python-gflags (1.5.1-4) — Always use SOURCE_DATE_EPOCH from the environment.
  • redis:
    • 5:4.0.6-3 — Use --clients argument to runtest to force single-threaded operation over using taskset.
    • 5:4.0.6-4 — Re-add procps to Build-Depends. (#887075)
    • 5:4.0.6-5 — Fix a dangling symlink (and thus a broken package). (#884321)
    • 5:4.0.7-1 — New upstream release.
  • redisearch (1.0.3-1, 1.0.4-1 & 1.0.5-1) — New upstream releases.
  • trydiffoscope (67.0.0) — New upstream release.

I also sponsored the following uploads:
