Here is my monthly update covering what I have been doing in the free software world in October 2017 (previous month):
- Wrote and released python-gfshare, a Python library that implements Shamir’s method for secret sharing, a cryptography technique to split a file into multiple parts. I blogged about it earlier in the month.
- Improved the new-style URL handling in the 2.x branch of the Django web framework to check for incorrectly migrated calls from the old system. [...]
- Added support for Python 3, Django 1.9 & Django 2.0 to django-auto-one-one-to-one, my library to cleanly manage related model instances.
- Proposed two small pull requests for Redisearch, a search engine module for the Redis key-value storage database:
- In Peter Bengtsson's new django-cache-memoize library, suggested an addition to the store_result documentation. [...]
- Made two pull requests for django-auditlog, a Django app that maintains an audit trail of changes in your application:
- Yet more Lintian hacking (previously):
- New features:
- Warn when packages unnecessararily set dpkg-architecture(1) variables. (#793554)
- Check for files that use content from the /etc/init.d/skeleton template. (#879152)
- Warn about certain files under debian/* that contain trailing whitespace characters. (#748405)
- Ignore embedded jQuery libraries for Doxygen. (#736360)
- Warn about Django libraries that do not depend on Django itself. (#877292)
- Check for Python modules with overly generic names such as tests or test. (#875964)
- Warn if packages set CFLAGS if the value of DEB_BUILD_OPTIONS contains noopt. (#718640)
- Ignore embedded jQuery libraries for Doxygen. (#736360)
- Warn about empty fields in debian/control. (#744388)
- Add bionic as known Ubuntu distribution. (#880115)
- Warn if native systemd .service files only wrap the existing SysV/LSB init scripts. (#870704)
- Emit new empty-section-field tag instead of uninitialized value warnings on an empty Section: field. (#878515)
- Warn about debian/watch files using insecure URIs, similar to vcs-field-uses-insecure-uri. (#849515)
- Include the offending URI in debian-watch-uses-insecure-uri output, not the line number.
- Allow empty md5sums files. (#781372)
- Move latest-debian-changelog-entry-without-new-date tag into a new check of type source. (#873612)
- Add cwl-runner to the list of known interpreters. (#851126)
- Also match packages named python2-* as relating to the Python 2.x migration.
- Bug fixes:
- Don't error out when AppStream metadata is invalid; emit appstream-metadata-invalid instead. (#879661)
- Actually check for a dependency on sensible-utils before emitting script-needs-depends-on-sensible-utils. (#877439)
- Avoid a false positives in debian-control-has-empty-field when the field is wrapped onto a new line. (#879977)
- Drop README.source from files to check against file-contains-trailing-whitespace as it can include literal quotes from upstreams that would be ideally left intact.
- Lower the severity of package-installs-java-bytecode from E: to W:. (#879862)
- Do not trigger package-installs-java-bytecode if the path contains WEB-INF, demo, doc etc. (#879860)
- Verify files triggering package-installs-java-bytecode files really are Java .class files. (#879861)
- Check the Recommends field as well when testing scripts for script-needs-depends-on-sensible-utils. (#879953)
- Ignore the "magic" http://sf.net/ redirector URI for the debian-watch-uses-insecure-uri tag. (#879206)
- Revert addition of "none were" -> "none was" multiword spelling correction as it is "acceptable beyond serious criticism". (#878457)
- Drop copyright-year-in-future; too error prone and time-consuming to maintain given the severity of the issues it can find. (#877766)
- Exempt debian/copyright from the license-problem-non-free-RFC tag to avoid false-positives "meta" references. (#877999)
- Avoid warning for init.d-script-not-marked-as-conffile when the init.d script does not exist as we will already be alerted via the init.d-script-not-included-in-package tag.
- Do not emit python-foo-but-no-python3-foo for packages ending with -common.
- Add missing example-script-uses-deprecated-nodejs-location tag. (#877142)
- Correct invalid link to upgrading-checklist in Standards-Version checks. (#878184)
- Add a note to orig-tarball-missing-upstream-signature regarding support in pristine-tar and git-buildpackage.
- Add example on how to remove trailing whitespace with sed.
- Split out checks for debconf-config-not-executable into a separate test protected by a Test-Requires now that dpkg ≥ 1.19.0 will bail out on that condition.
- Correct Depends of python2.7 → python3 in a Python 3 test package.
- Add test for ignoring python-foo-doc packages for the Python 3 migration and correct short descriptions of test packages.
- New features:
- Finally, I was interviewed by HostingAdvice about my role as Debian Project Leader.
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.
This month I:
- Presented at All Things Open, 2017 in Raleigh, NC, United States.
- Attended the third Reproducible Builds summit in Berlin, Germany.
- Presented at the inaugural Freenode #live conference in Bristol, United Kingdom.
- In Debian, I:
- Kept isdebianreproducibleyet.com up to date.
- Submitted 10 patches to fix specific reproducibility issues in argagg, cadvisor, fmtlib, geographiclib, live-build, plr, polygen, python-amqp, rcs & sdlgfx.
- Made the following non-maintainer uploads (NMUs) to Debian to fix reproducibility issues:
- Updated the try.diffoscope.org SSL key.
- Categorised a large number of packages and issues in the Reproducible Builds "notes" repository.
- Worked on publishing our weekly reports. (#128, #129, #130 & #131)
I also made the following changes to our tooling:
diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues.
- Improve names in output of "internal" binwalk members. (#877525).
- Don't crash on malformed md5sums files. (#877473).
- Omit misleading "any of" prefix when only complaining about a single module on import. [...]
- Adjust tests as ps2ascii now varies its output on timezone. [...]
strip-nondeterminism is our tool to remove specific non-deterministic results from a completed build.
- Clojure considers .class file to be stale if it shares the same timestamp of the .clj. We thus adjust the timestamps of the .clj to always be younger. (#877418).
- Print a message in --verbose mode if no canonical time was specified. [...]
buildinfo.debian.net is my experiment into how to process, store and distribute .buildinfo files after the Debian archive software has processed them.
- Always show SHA-256 checksums, regardless of the browser viewport size. [...]
- Add an API endpoint to fetch specific .buildinfo files for a certain package/version/architecture. [...]
My activities as the current Debian Project Leader are covered in my "Bits from the DPL" email to the debian-devel-announce mailing list.
This month I have been paid to work 18 hours on Debian Long Term Support (LTS). In that time I did the following:
- "Frontdesk" duties, triaging CVEs, etc.
- Followed up on a large number of upstream "pings" that have been left dormant.
- Issued DLA 1121-1 to fix an out-of-bounds read vulnerability in curl where a malicious FTP server could abuse this to prevent clients from interacting with it.
- Issued DLA 1123-1 for the "Go" programming language where an attacker could generate a MIME request such that the server ran out of file descriptors.
- Issued DLA 1126-1 for the libxfont font selection and rasterisation library, correcting two vulnerabilities, both involving the library being tricked into reading invalid/random memory.
- Issued DLA 1134-1 for sdl-image1.2, an image loading library. A maliciously-crafted .xcf file could cause a stack-based buffer overflow resulting in potential code execution.
- 2.0~beta1-1 — New upstream 2.x release.
- 1.11.6-1 — New upstream bugfix release.
- gunicorn (19.6.0-10+deb9u1) — Prepared a release for stable to avoid a runtime dependency on a compiler. (#877722)
- Drop the Debian-specific /etc/redis/redis-server.pre-up.d (etc.) hooks and remove them if unchanged.
- Include systemd redis-server@.service and redis-sentinel@.service template files to easily run multiple Redis instances. (#877702)
- Patch redis.conf and sentinel.conf with quilt instead of maintaining our own versions under debian/.
- Add input validity checking to cluster config slot numbers to fix CVE-2017-15047. (#878076)
- Drop debian/bin/generate-parts now we aren't calling it.
- Correct Bash-ism in NEWS file.
- 4:4.0.2-5: Replace the existing patch for CVE-2017-15047 with an upstream-blessed version that covers another case.
- redisearch (0.21.3-5) — Initial release.
- docbook2man (2.0.0-40) — Correct spelling mistakes in binaries and other misc packaging tidying.
- python-redis (2.10.6-1) — New upstream release.
- bfs (1.1.3-1) — New upstream release.
