Chris Lamb: Free software activities in September 2017

Here is my monthly update covering what I have been doing in the free software world in September 2017 (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:
  • Published a short blog post about how to determine which packages on your system are reproducible. [...]
  • Submitted a pull request for Numpy to make the generated config.py files reproducible. [...]
  • Provided a patch to GTK upstream to ensure the immodules.cache files are reproducible. [...]
  • Within Debian:
    • Updated isdebianreproducibleyet.com, moving it to HTTPS, adding cachebusting as well as keeping the number up-to-date.
    • Submitted the following patches to fix reproducibility-related toolchain issues:
      • gdk-pixbuf: Make the output of gdk-pixbuf-query-loaders reproducible. (#875704)
      • texlive-bin: Make PDF IDs reproducible. (#874102)
    • Submitted a patch to fix a reproducibility issue in doit.
  • Categorised a large number of packages and issues in the Reproducible Builds "notes" repository.
  • Chaired our monthly IRC meeting. [...]
  • Worked on publishing our weekly reports. (#123, #124, #125, #126 & #127)


I also made the following changes to our tooling:
reproducible-check

reproducible-check is our script to determine which packages actually installed on your system are reproducible or not.

  • Handle multi-architecture systems correctly. (#875887)
  • Use the "restricted" data file to mask transient issues. (#875861)
  • Expire the cache file after one day and base the local cache filename on the remote name. [...] [...]
I also blogged about this utility. [...]
diffoscope

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

  • Filed an issue attempting to identify the causes behind an increased number of timeouts visible in our CI infrastructure, including running a number of benchmarks of recent versions. (#875324)
  • New features:
    • Add "binwalking" support to analyse concatenated CPIO archives such as initramfs images. (#820631).
    • Print a message if we are reading data from standard input. [...]
  • Bug fixes:
    • Loosen matching of file(1)'s output to ensure we correctly also match TTF files under file version 5.32. [...]
    • Correct references to path_apparent_size in comparators.utils.file and self.buf in diffoscope.diff. [...] [...]
  • Testing:
    • Make failing some critical flake8 tests result in a failed build. [...]
    • Check we identify all CPIO fixtures. [...]
  • Misc:
    • No need for try-assert-except block in setup.py. [...]
    • Compare types with identity not equality. [...] [...]
    • Use logging.py's lazy argument interpolation. [...]
    • Remove unused imports. [...]
    • Numerous PEP8, flake8, whitespace, other cosmetic tidy-ups.

strip-nondeterminism

strip-nondeterminism is our tool to remove specific non-deterministic results from a completed build.

  • Log which handler processed a file. (#876140). [...]

disorderfs

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



Debian My activities as the current Debian Project Leader are covered in my monthly "Bits from the DPL" email to the debian-devel-announce mailing list.
Lintian I made a large number of changes to Lintian, the static analysis tool for Debian packages. It reports on various errors, omissions and general quality-assurance issues to maintainers: I also blogged specifically about the Lintian 2.5.54 release.

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.

  • Comparators:
    • Display magic file type when we know the file format but can't find file-specific details. (Closes: #850850).
    • Ensure our "APK metadata" file appears first, fixing non-deterministic tests. (998b288)
    • Fix APK extration with absolute filenames. (Closes: #850485).
    • Don't error if directory containing ELF debug symbols already exists. (Closes: #850807).
    • Support comparing .ico files (Closes: #850730).
    • If we don't have a tool (eg. apktool), don't blow up when attempting to unpack it.
  • Output formats:
    • Add Markdown output format. (Closes: #848141).
    • Add RestructuredText output format.
    • Use an optimised indentation routine throughout all presenters.
    • Move text presenter to use the Visitor pattern.
    • Correctly escape value of href="" elements (re. #849411).
  • Tests:
    • Prevent FTBFS by loading fixtures as UTF-8 in case surrounding terminal is not Unicode-aware. (Closes: #852926).
    • Skip tests if binutils can't handle the object file format. (Closes: #851588).
    • Actually compare the output of text/ReST/Markdown formats to fixtures.
    • Add tests for: Comparing two empty directories, HTML output, image.ICOImageFile, --html-dir, --text-color & no arguments (beyond the filenames) emits the text output.
  • Profiling:
    • Count the number of calls, not just the total time.
    • Skip as much profiling overhead when not enabled for a ~2% speedup.
  • Misc:
    • Alias an expensive Config() lookup for a 10% optimisation.
    • Avoid expensive regex creation until we actually need it, speeding up diff parsing by 2X.
    • Use Pythonic logging functions based on __name__, etc.
    • Drop milliseconds from logging output.

buildinfo.debian.net

buildinfo.debian.net is my experiment into how to process, store and distribute .buildinfo files after the Debian archive software has processed them.

  • Store files directly onto S3.
  • Drop big unique_together index to save disk space.
  • Show SHA256 checksums where space permits.


Debian LTS

This month I have been paid to work 12.75 hours on Debian Long Term Support (LTS). In that time I did the following:
  • "Frontdesk" duties, triaging CVEs, etc.
  • Issued DLA 773-1 for python-crypto fixing a vulnerability where calling AES.new with an invalid parameter could crash the Python interpreter.
  • Issued DLA 777-1 for libvncserver addressing two heap-based buffer overflow attacks based on invalid FramebufferUpdate data.
  • Issued DLA 778-1 for pcsc-lite correcting a use-after-free vulnerability.
  • Issued DLA 795-1 for hesiod which fixed a weak SUID check as well as removed the hard-coding of a fallback domain if the configuration file could not be found.
  • Issued DLA 810-1 for libarchive fixing a heap buffer overflow.

Uploads
  • python-django:
    • 1:1.10.5-1 New upstream stable release.
    • 1:1.11~alpha1-1 New upstream experimental release.
  • gunicorn (19.6.0-10) Moved debian/README.Debian to debian/NEWS so that the recent important changes will be displayed to users when upgrading to stretch.
  • redis:
    • 3:3.2.6-2 & 4:4.0-rc2-2 Tidy patches and rename RunTimeDirectory to RuntimeDirectory in .service files. (Closes: #850534)
    • 3:3.2.6-3 Remove a duplicate redis-server binary by symlinking /usr/bin/redis-check-rdb. This was found by the dedup service.
    • 3:3.2.6-4 Expand the documentation in redis-server.service and redis-sentinel.service regarding the default hardening options and how, in most installations, they can be increased.
    • 3:3.2.6-5, 3:3.2.6-6, 4:4.0-rc2-3 & 4:4.0-rc2-4 Add taskset calls to try and avoid build failures due to parallelism in upstream test suite.

I also made the following non-maintainer uploads:
  • cpio:
    • 2.12+dfsg-1 New upstream release (to experimental), refreshing all patches, etc.
    • 2.12+dfsg-2 Add missing autoconf to Build-Depends.

Paul Wise: Check All The thingS!

check-all-the-things (aka cats, Meow!) is a tool that aims to make it easy to know which tools can be used to check a directory tree and to make it easy to run those tools on the directory tree. The tree could either be a source tree or a build tree or both. It aims to check as much of the tree as possible so the output can be very verbose and have many false positives. It is not for the busy, lazy or noise intolerant. It runs the checks by matching file names and MIME types against those registered for a list of checks. Each check has a set of dependencies, flags, filename wildcards, MIME type wildcards, comments and prerequisite commands. By default it: It runs all checks for the current distro/release except: There are command-line options to customise the behaviour and automatic bash shell completion via argcomplete. There are 177 checks (including TODO ones) in 73 different categories. There are an additional 224 not-well-specified TODO items for new checks in comments. It is exceptionally easy to add new checks once one knows how to use the tool one wants to add. At this point in time it is probably not a good idea to run it in an untrusted directory tree for several reasons: The project initially started as really hacky wiki page full of commands to run. At some point I figured it was time to make this actually be maintainable and started on a project to do that. At around the same time Jakub Wilk was working on maquack to replace the wiki page. Somehow I found out about it and talked to him about it. It was vastly less hacky than my version so I ended up taking it over and continuing it under the check-all-the-things name. I polished it for the last two years and finally released it into Debian unstable during DebCamp16.

David Bremner: Converting PDFs to DJVU

Today I was wondering about converting a pdf made from scan of a book into djvu, hopefully to reduce the size, without too much loss of quality. My initial experiments with pdf2djvu were a bit discouraging, so I invested some time building gsdjvu in order to be able to run djvudigital. Watching the messages from djvudigital I realized that the reason it was achieving so much better compression was that it was using black and white for the foreground layer by default. I also figured out that the default 300dpi looks crappy since my source document is apparently 600dpi. I then went back an compared djvudigital to pdf2djvu a bit more carefully. My not-very-scientific conclusions: Perhaps most compellingly, the output from pdf2djvu has sensible metadata and is searchable in evince. Even with the --words option, the output from djvudigital is not. This is possibly related to the error messages like
Can't build /Identity.Unicode /CIDDecoding resource. See gs_ciddc.ps .
It could well be my fault, because building gsdjvu involved guessing at corrections for several errors. Some of these issues have to do with building software from 2009 (the instructions suggestion building with ghostscript 8.64) in a modern toolchain; others I'm not sure. There was an upload of gsdjvu in February of 2015, somewhat to my surprise. AT&T has more or less crippled the project by licensing it under the CPL, which means binaries are not distributable, hence motivation to fix all the rough edges is minimal.

James McCoy: porterbox-logins

Some time ago, pabs documented his setup for easily connecting to one of Debian's porterboxes based on the desired architecture. Similarly, he submitted a wishlist bug against devscripts specifying some requirements for a script to make this functionality generally accessible to the developer community. I have yet to follow up on that request mainly due to ENOTIME for developing new scripts outright. I also have my own script I had been using to get information on available Debian machines. Recently, this came up again on IRC and jwilk decided to actually implement pabs' DNS alias idea. Now, one can use $arch-porterbox.debian.net to connect to a porterbox of the specified architecture. Preference is given to debian.org domains when there are both debian.org and debian.net porterboxes, and it's a simple use first listed machine if there are multiple available porterboxes. This is all well and good, but if you have SSH's StrictHostKeyChecking enabled, SSH will rightly refuse to connect. However, OpenSSH 6.5 added a feature called hostname canonicalization which can help. The below ssh_config snippet allows one to run ssh $arch-porterbox or ssh $arch-porterbox.debian.net and connect to one of the porterboxes, verifying the host key against the canonical host name.
Host *-porterbox
  HostName %h.debian.net
Match host *-porterbox.debian.net
  CanonicalizeHostname yes
  CanonicalizePermittedCNAMEs *-porterbox.debian.net:*.debian.org

      2 debhelper (>= 9.2)
      1 debhelper (>= 9.2~)

Is it a way to protest against the current debhelper's version scheme?

Jakub Wilk: Joys of East Asian encodings

In i18nspector I try to support all the encodings that were blessed by gettext, but it turns out to be more difficult than I anticipated:
$ roundtrip()   c=$(echo $1   iconv -t $2); printf '%s -> %s -> %s\n' $1 $c $(echo $c   iconv -f "$2");  
$ roundtrip   EUC-JP
  -> \ -> \
$ roundtrip   SHIFT_JIS
  -> \ ->  
$ roundtrip   JOHAB
  -> \ ->  
Now let's do the same in Python:
$ python3 -q
>>> roundtrip = lambda s, e: print('%s -> %s -> %s' % (s, s.encode(e).decode('ASCII', 'replace'), s.encode(e).decode(e)))
>>> roundtrip(' ', 'EUC-JP')
  -> \ -> \
>>> roundtrip(' ', 'SHIFT_JIS')
  -> \ -> \
>>> roundtrip(' ', 'JOHAB')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <lambda>
UnicodeEncodeError: 'johab' codec can't encode character '\u20a9' in position 0: illegal multibyte sequence
So is 0x5C a backslash or a yen/won sign? Or both? And what if 0x5C could be a second byte of a two-byte character? What could possibly go wrong?

Jakub Wilk: More spell-checking

Have you ever wanted to use Lintian's spell-checker against arbitrary files? Now you can do it with spellintian:
$ zrun spellintian --picky /usr/share/doc/RFC/best-current-practice/rfc*
/tmp/0qgJD1Xa1Y-rfc1917.txt: amoung -> among
/tmp/kvZtN435CE-rfc3155.txt: transfered -> transferred
/tmp/o093khYE09-rfc3481.txt: unecessary -> unnecessary
/tmp/4P0ux2cZWK-rfc6365.txt: charater -> character
mwic (Misspelled Words In Context) takes a different approach. It uses classic spell-checking libraries (via Enchant), but it groups misspellings and shows them in their contexts. That way you can quickly filter out false-positives, which are very common in technical texts, using visual grep:
$ zrun mwic /usr/share/doc/debian/social-contract.txt.gz

Jakub Wilk: ~/.netrc security

TL;DR: don't put valuable passwords in ~/.netrc In the olden days, the ~/.netrc file was used for storing FTP usernames and passwords. These days we have clients of other protocols that use said file. Perhaps your IMAP or SMTP client use it. So you put your e-mail accounts password into ~/.netrc, and then meticulously configured the clients to always connect via TLS and to verify server certificates. You feel secure. But you shouldn't. Here's how an attacker capable of MiTM can exploit wget to steal ~/.netrc passwords: 1) Alice tries to download a file over HTTP:
$ wget http://xkcd.com/538/
2) Eve takes over the HTTP connection, sending a redirection response:
HTTP/1.1 303 See Other
Location: http://supersecuremail.example.net/
3) Alice's wget follows the redirection. 4) Eve takes over the connection to supersecuremail.example.net, requesting password authentication:
HTTP/1.1 401 Unauthorized
WWW-Authenticate: Basic realm="moo"
5) Alice's wget sends the supersecuremail.example.net password straight to Eve.

Ben Armstrong: Taskwarrior new blog, getting involved

The Taskwarrior Team has just started a blog, kicking it off with a series of articles about development of Taskwarrior itself. Go, team! Almost from the moment I started using Taskwarrior (thanks to Jakub WIlk for an excellent job maintaining this) I knew I had finally found the todo system that I could love. Right away, I started hanging out with the Taskwarrior community at #taskwarrior @ irc.freenode.net and found out what an awesome bunch of people they are, both developers and users alike. I have plunged in with bug reports and feature requests, and am helping get more Taskwarrior-related things into Debian. In NEW right now I have uploaded several of the dependencies needed by my ITP of taskwarrior-web. It s looking like I ll have that finished later this month or early next month. Also, I have uploaded a wheezy backport of Taskwarrior itself (aka task ) which, if all goes well, enters the archive next week.

Paul Wise: Inadequate software

Just 168 of the 4961 packages (3%) I have installed are inadequate. Unfortunately those packages collectively have 3440 inadequacies. How much of the software on your system has these inadequacies? You can find out today by installing Jakub Wilk's software, which is appropriately named adequate. It is now available in Debian unstable. I recommend enabling the apt hook which notifies you when software you are installing is inadequate. Other ways of being notified when you are installing inadequate software include apt-listbugs and debsecan. If you are interested in software quality, Debian's QA activities wiki page provides a good overview of the quality assurance activities that are being worked on within the context of Debian. If you want to provide better quality software for Debian, please keep an eye on the PTS pages for software you maintain. You can also run various automated checks on your software before you make new releases or upload them to the Debian archive. More people are needed to improve and expand upon Debian's existing quality assurance activities and infrastructure. Come join us today!

Jakub Wilk: Internationalization environment variables

Setting internationalization environment variables is a bit tricky. For example, this:
$ LANG=sv_SE.UTF-8 stat /nonexistent
may look like a way to make stat(1) print the error message in Swedish. Yet there are many ways it could go wrong:
  1. LC_MESSAGES could be set in the environment, overriding LANG.
  2. LC_ALL could be set, overriding both LC_MESSAGES and LANG.
  3. LANGUAGE could be set, overriding LC_ALL, LC_MESSAGES, and LANG. For extra complexity, LANGUAGE has no effect if LC_MESSAGES is effectively set to C. (Also, this variable is a GNUism.)
  4. The locale could be simply missing from the system.
To make these things a little less intricate, I wrote localehelper. It's a bit like env(1), but it takes care of: This does the right thing:
$ localehelper LANG=sv_SE.UTF-8 stat /nonexistent
stat: kan inte ta status p   /nonexistent : Filen eller katalogen finns inte

Jakub Wilk: All those translations, how did you ever manage it?

I've just released initial version of gettext-inspector, a tool for checking gettext PO/POT/MO files. While it's in an early stage of development, it's already able to detect wide rage of problems. For example, this is what it emits on my system:
$ gettext-inspector /usr/share/locale/*/LC_MESSAGES/*.mo   cut -d ' ' -f 1,3   sort   uniq -c   sort -rn

Vasudev Kamath: Weekly Log - 22092012

After thinking a while I thought I should record my weekly FLOSS work and I'm starting by this week. This week I'm on vacation and in home town so I could give bit more time for my FLOSS activity. So here it goes this weeks work Bug Squashing
Both these packages are uploaded to unstable first RC bug was related to Debian Installer hence was unblocked before we could file unblock-request. Kartik filed an unblock-request and adsb unblocked it happily and both the packages landed in unstable. New Packages
Both these packages will be backported once Wheezy freezes. One pending wnpp is left on Debian-IN which I've left for Kartik to finish ;-). Font Package Helper I bumped version on dh-make-font[1] to 0.3 now it accepts upstream URL with -u, --upstream switch this will be placed in Homepage: field of control file and in Source: field of copyright file. Probably I need to think of introducing xz compression to original source tarball where upstream is not giving any tarball and probably rewrite it using Perl so it can get included dh-make package. Already a bug filed to get it included in dh-make package 658154. [1] http://anonscm.debian.org/gitweb/?p=debian-in/dh-make-font.git;a=summary Misc and Learnings
Well that is it for this week. Hopefully I will have new stuffs to put up here for the next week, till then Cya.

Jakub Wilk: Spell-checker for irssi

I tried many spell-checkers for irssi, and they all sucked (and some of them were also completely insane). So I took the one that seemed least crazy and forked it.

Next.
