My Free Software Activities in November 2016

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you’re interested in Java, Games and LTS topics, this might be interesting for you.

Debian Android

  • Chris Lamb was so kind to send in a patch for apktool to make the build reproducible (#845475). Although this was not enough to fix the issue it set me on the right path to eventually resolve bug number 845475.

Debian Games

  • I packaged a couple of new upstream releases for extremetuxracer, fifechan, fife, unknown-horizons, freeciv, atanks and armagetronad. Most notably fifechan was accepted by the FTP team which allowed me to package new versions of fife and unknown-horizons which are both back in testing again. I expect that upstream will make their final release sometime in December. Atanks has been orphaned a while ago and since upstream is still active and I kinda like the game I decided to adopt it. I also uploaded a backport of Freeciv 2.5.6 to jessie-backports.
  • In November we received a bunch of RC bug reports again because, hey, it is almost time for the Freeze, let’s break some packages. Thus I spent some time fixing freeorion (#843132), pokerth (#843078), simutrans (#828545), freeciv (#844198) and warzone2100 (#844870).
  • I also updated the debian-games blend, we are at version 1.6 now, and made some smaller adjustments. The most important change was adding a new binary package, games-all, that installs..well, all! I know this will make at least one person on this planet happy. Actually I was kind of forced into adding it because blends-dev automatically creates it as a requirement for choosing blends with the Debian Installer. But don’t be afraid games-all only recommends games-finest, the rest is suggested.
  • Last but not least I worked on performous and could close a wishlist bug report (#425898). The submitter asked to suggest some free song packages for this karaoke game.

Debian Java

  • I sponsored uncommons-watchmaker for Kai-Chung and also reviewed libnative-platform-java and granted upload rights to him.
  • I packaged new upstream releases of lombok-patcher, electric, undertow, sweethome3d and sweethome3d-furniture-editor.
  • I spent quite some time on reviewing (especially the copyright review took most of the time) and improving the packaging for tycho (#816604) which is a precondition for packaging the latest upstream release of Eclipse, a popular Java IDE. Luca Vercelli has been working on it for the last couple of months and he did most of the initial packaging. Unfortunately I was only able to upload the package last week which means that the chances for updating Eclipse for Stretch are slim.
  • Due to time constraints I could not finish the Netbeans update in time which I had started back in October. This is on my priority list for December now.
  • Several security issues were reported against Tomcat{6,7,8}. I helped with reviewing some of the patches that Emmanuel prepared for Jessie and worked on fixing the same bugs in Wheezy.

Debian LTS

This was my ninth month as a paid contributor and I have been paid to work 11 hours on Debian LTS, a project started by Raphaël Hertzog. In that time I did the following:

  • From 14. November until 21. November I was in charge of our LTS frontdesk. I triaged bugs in teeworlds, libdbd-mysql-perl, bash, libxml2, tiff, firefox-esr, drupal7, moin, libgc, w3m and sniffit.
  • DLA-715-1. Issued a security update for drupal7 fixing 2 CVE.
  • DLA-717-1. Issued a security update for moin fixing 2 CVE.
  • DLA-728-1. Issued a security update for tomcat6 fixing 8 CVE. (Debian bug #845385 was assigned a CVE later).
  • DLA-729-1. Issued a security update for tomcat7 fixing 8 CVE. (Debian bug #845385 was assigned a CVE later).
  • Especially the patches and the subsequent testing for CVE-2016-0762 and CVE-2016-6816 required most of the time.

Non-maintainer uploads

  • I uploaded an NMU for angband to fix #837394. The patch was kindly prepared by Adrian Bunk.

It is already this time of the year again. See you next year for another report. 🙂

My Free Software Activities in October 2016

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you’re interested in Android, Java, Games and LTS topics, this might be interesting for you.

Debian Android

Debian Games

  • I fixed RC bugs in lordsawar (#839323) and doomsday (#839338).
  • I packaged new upstream releases of atanks, lordsawar, blockattack and peg-e.
  • I completed the Bullet transition (#839243). Bullet 2.85 has also been released this month but it is now too late for Stretch because the transition freeze is already on the 5th of November. I expect more point releases a la 2.85.x during the coming weeks and I intend to provide an updated package in experimental soon.
  • I did some cleanups, package upgrades and bug fixes for box2d and redeclipse (apparently redeclipse-server requires the -data package to be present now).
  • I uploaded Redeclipse 1.5.6 to jessie-backports in the hope that more players will be able to connect to the multiplayer servers. Unfortunately network compatibility breaks rather frequently.
  • I applied a patch from Gianfranco Costamagna to address an Multiarch installation issue (#841824) in FreeOrion.

Debian Java

Debian LTS

This was my eight month as a paid contributor and I have been paid to work 13 hours on Debian LTS, a project started by Raphaël Hertzog. In that time I did the following:

  • From 10. October until 17. October I was in charge of our LTS frontdesk. I triaged bugs in libgd2, graphicsmagick, libxrender, mupdf, libxfixes, guile-2.0, glance, inspircd, libxi, libxv, libxst, spip, libxml2, libarchive and jasper.
  • DLA-648-1. Issued a security update for c-ares fixing 1 CVE.
  • DLA-664-1. Issued a security update for libxrender fixing 2 CVE.
  • DLA-666-1. Issued a security update for guile-2.0 fixing 2 CVE.
  • DLA-667-1. Issued a security update for libxv fixing 1 CVE.
  • DLA-668-1. Issued a security update for libass fixing 2 CVE. I triaged CVE-2016-7970 and marked the version in Wheezy as not affected.
  • DLA-673-1. Issued a security update for kdepimlibs fixing 1 CVE.

Non-maintainer uploads

  • I fixed various RC bugs in gnudoq and xsok which are not maintained by the Games Team. The following games are available in Stretch again: gnudoq (#817296, #817484), xsok (#817738) and I also worked on four more bug fixes to improve the game’s desktop integration and internationalization support.
  • I fixed another RC bug in trackballs (#831119) but while I was working on the update I discovered that the game frequently segfaults which makes it kind of unplayable (#839788). I haven’t found a solution yet but I suspect the switch to guile-2.0 and related patches introduced this behavior.

QA

  • I uploaded a new revision of criticalmass and applied a patch from Adrian Bunk to fix #811816, a FTBFS.
  • I triaged an RC bug for raptor2 (#824735) and the issue could be closed after the bug reporter confirmed that raptor2 built fine again.

My Free Software Activities in September 2016

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you’re interested in Android, Java, Games and LTS topics, this might be interesting for you.

Debian Android

Debian Games

  • I packaged a new upstream release of hyperrogue, a rogue-like game settled in a non-euclidian world, fixing one RC bug (#811991). I uploaded two more revisions later that addressed  build failures on arm64 and hppa.
  • I fixed more RC bugs (build failures with GCC-6) in torus-trooper (#835712) and fife (#811858).
  • I packaged new upstream releases of pygame-sdl2, renpy, freeorion, netrek-client-cow, redeclipse, redeclipse-data, hitori, atomix, adonthell and adonthell-data.
  • I updated gtkballs and fixed a documentation bug (#820588) but also a /usr/share/locale issue that prevented the actual use of the translations.
  • I raised the severity of #797998 to grave in unknown-horizons because the game cannot be started currently. In order to fix this issue I packaged a new build-dependency, fifechan, which is currently awaiting approval by the FTP team. As soon as fifechan got accepted I will upload new upstream releases of fife and unknown-horizons.
  • I released debian-games 1.5, a Debian blend and collection of games metapackages.
  • Hardening-wrapper has been deprecated for some time and this issue became release critical now. I updated cookietool, alex4 and netrek-client-cow to use dpkg-buildflags instead.
  • Together with Russel Coker I packaged a new upstream release of warzone2100. This package would benefit from a new regular uploader. If you are interested in it, please get involved. (Same story for hyperrogue, redeclipse, renpy and unknown-horizons and many other games.)
  • I started a new Bullet transition (#839243). The package is currently waiting in the NEW queue and I hope to complete this work in October.
  • I triaged #838199 and reassigned the issue to fonts-roboto. Initially I prepared an NMU but eventually the maintainer uploaded a new revision himself. It is now possible to install the hinted and unhinted versions of fonts-roboto together which also resolved former installation problems with kodi and freeorion.

Debian Java

  • I packaged new upstream releases of undertow, activemq and jackrabbit.
  • I fixed RC bugs in libphonenumber (#836768), wagon2 (#837022) and activemq (#839244).
  • I updated syncany in experimental and simplified the packaging a little. Unfortunately upstream has been on hiatus for the past year and we haven’t seen new releases in the meantime. Nevertheless give it a try, even though it is still alpha software, it’s an useful cloud-storage and synchronization tool.
  • I sponsored a new upstream release of freeplane for Felix Natter.
  • I prepared and uploaded security updates for jackrabbit and zookeeper in Jessie.

Debian LTS

This was my eight month as a paid contributor and I have been paid to work 12,25 hours on Debian LTS, a project started by Raphaël Hertzog. In that time I did the following:

  • From 12. September until 19. September I was in charge of our LTS frontdesk. I triaged bugs in tiff3, mysql-5.5, curl, dropbear, mantis, icu, dwarfutils, jackrabbit, zendframework, zookeeper and graphicsmagick. For the latter I skimmed through all commits since the last version to identify the patches that fix the recent issues in graphicsmagick. I also answered questions on the mailing list and contacted Diego Biurrun again about his progress with libav. It is now anticipated that Hugo Lefeuvre and Diego will issue a new libav security release this month.
  • I reviewed and tested a patch by Raphaël Hertzog for roundcube.
  • DLA-629-1. Issued a security update for jackrabbit fixing 1 CVE.
  • DLA-630-1. Issued a security update for zookeeper fixing 1 CVE.
  • DLA-633-1. Issued a security update for wordpress fixing 7 CVE. This one also required backports of certain functions from newer releases and a database upgrade that required careful testing.
  • I also issued DLA-622-1 and DLA-623-1, two security issues that I already mentioned last month. It was discovered that Debian’s versions of Tomcat were vulnerable to a root privilege escalation issue. However it was also necessary that another exploit, for instance in a web application, could be used to gain write access as the tomcat user. Former security issues were already fixed and new ones are not known. Nevertheless since a zero-day exploit could not be ruled out, the issue was embargoed for a month to give other distributions time to fix this issue as well. You can read more about this topic at legalhackers.com.

Non-maintainer uploads

Misc

  • I packaged a new upstream release of MediathekView.
  • I uploaded a new revision of xarchiver and applied a patch from Helmut Grohne that made it possible to cross-build the package.

My Free Software Activities in August 2016

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you’re interested in Android, Java, Games and LTS topics, this might be interesting for you.

Debian Android

Debian Games

  • I started the month with package updates for foobillardplus, tuxpuck, etw, cube2, cube2-data and neverball.
  • I released a new revision of triplane to fix a reproducible build issue.
  • I packaged a new upstream release of springlobby.
  • I fixed GCC-6 FTBFS bugs in stormbaancoureur and love and updated both packages to use modern Debian helpers (stormbaancoureur needed it badly).
  • I invested some time to package Liquidwar 6 (#680023) and attached my preliminary work to the bug report. Liquidwar 6 has been in the works for a long time now and is a complete rewrite of the original Liquidwar game. The graphics are much more polished and dozens of new levels are available. I didn’t complete my work on Liquidwar 6 because, at least on my system, the game constantly consumes 100% CPU time. Network modus isn’t finished yet and it still depends on SDL 1. Nowadays I’m only interested in SDL 2 (or similar) games though because I think the library is more future-proof and SDL 1 will probably become a burden for future maintainers.
  • In the second half of the month I fixed a couple of RC bugs again caused by the Boost 1.61 transition and yes still more GCC-6 bugs : libclaw (GCC-6 and Boost 1.61 issues, new upstream release), freeorion (Boost 1.61 FTBFS, #833773. This one was arguably a regression in Boost 1.61 and I filed #833794 because of it), pokerth (GCC-6 RC bugs. I also took the opportunity to implement systemd support for pokerth-server and I modified the package to run the server as the _pokerth system user out-of-the-box.), 0ad (missing build-dependency on python).
  • Even music packages can pile up bug reports, so I went ahead and updated fretsonfire-songs-muldjord and fretsonfire-songs-sectoid.
  • In the last days of August 2016 I packaged a new upstream release of redeclipse and redeclipse-data, a first-person shooter. The older version was network-incompatible and long unsupported.

Debian Java

Debian LTS

This was my seventh month as a paid contributor and I have been paid to work 14,75 hours on Debian LTS, a project started by Raphaël Hertzog. In that time I did the following:

  • From 01. August to 07. August I was in charge of our LTS frontdesk. I triaged CVEs in wordpress, mysql-5.5, libsys-syslog-perl, libspring-java, curl and squid and answered questions on the debian-lts mailing list.
  • DLA-586-1. Issued a security update for curl fixing 2 CVE.
  • DLA-585-1. Announced the security update for firefox-esr which was prepared by Mike Hommey.
  • I was involved in an embargoed security issue that currently affects two source packages in Wheezy. The update will be released on 15. September 2016 and will be coordinated with Debian’s Security Team and other distributions. I will add more information next month.
  • DLA-610-1. I spent most of the time this month on triaging and fixing security issues in tiff3, a library providing support for the Tagged Image File Format (TIFF). 99 source packages currently build-depend on this library in Wheezy. In total I triaged 35 CVEs and fixed 23 of them. I could confirm that CVE-2015-1547, CVE-2016-5322, CVE-2016-5314, CVE-2016-5315, CVE-2016-5316, CVE-2016-5317 and CVE-2016-5320 were duplicates of other CVEs fixed in this update. The update hardened the library and fixed possible denial-of-service (application crash) and arbitrary code execution issues. I tested whenever possible against the provided reproducers (malicious tiff images). The tiff3 package now includes all currently available patches. Most of the current open vulnerabilities do not directly affect end-users since no binary package has been provided for the tiff tools in Wheezy. However they can still pose a threat to people who build these tools from source manually. Though the majority of users should not be affected. It is also unlikely that the remaining issues will be fixed by tiff’s upstream developers since they decided to remove the affected applications from newer releases but again most of them can’t be exploited since the tools are not built by default in this version.

Non-maintainer uploads

  • I did a NMU for pacman fixing one GCC-6 RC bug.

QA

  • I packaged a new upstream release of pygccxml and worked around a RC bug that threatened to remove spring. For similar reasons I filed #835121 against castxml that got quickly fixed by Gert Wollny.

My Free Software Activities in July 2016

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian.

Debian Android

Debian Games

  • This month GCC-6 bugs became release critical. I fixed and triaged those kind of bugs in games like supertransball2, berusky2, freeorion, bloboats, armagetronad and megaglest.
  • I packaged new upstream releases of scorched3d, bzflag, spring, springlobby, freeorion, freeciv and extremetuxracer.
  • Freeciv, one of the best strategy games ever by the way, also got a new binary package freeciv-client-gtk3. This package will eventually become the new default client to play the game in the future. You are welcome to test it.
  • I packaged a new upstream release of adonthell and adonthell-data. This game is built with Python 3 and SDL 2 now and also uses the latest version of swig to generate its sources. We will probably see only one other future upstream release of adonthell because the main developer has decided to move on after more than 15 years of development.
  • I fixed another RC bug in minetest, updated whichwayisup for this release cycle and moved the package to Git.

Debian Java

Debian LTS

This was my sixth month as a paid contributor and I have been paid to work 14,7 hours on Debian LTS. In that time I did the following:

  • DLA-554-1. I spent most of the time this month on completing my work on libarchive. I issued DLA-554-1 and fixed 18 CVE plus another issue which was later assigned CVE-2016-6250.
  • DLA-555-1. Issued a security update for python-django fixing 1 CVE.
  • DLA-561-1. Issued a security update for uclibc fixing 3 CVE.
  • DLA-562-1. Issued a security update for gosa fixing 1 CVE. I could triage another open CVE as not-affected after confirming that the issue had already been fixed two years ago.
  • DLA-568-1. Issued a security update for wordpress fixing 6 CVE. I decided to go ahead with this update because I could not find any regressions. Unfortunately this wasn’t true for my intended fix for CVE-2015-8834. The database upgrade did not succeed hence I decided to postpone the fix for CVE-2015-8834 until we can narrow down the issue.
  • DLA-576-1. Issued a security update for libdbd-mysql-perl fixing 2 CVE.
  • From 04. July to 10. July I was in charge of our LTS frontdesk. I triaged CVEs in librsvg, bind9, trn, pdns and drupal7 and answered questions on the debian-lts mailing list.

Misc and QA

  • I fixed another GCC-6 bug in wbar, a light and fast launch bar.
  • Childsplay and gvrng were orphaned last month. I updated both of them, fixed the RC-bug in childsplay (non-free font) and moved the packages to the Debian QA Group.

My Free Software Activities in June 2016

My monthly report covers what I have been doing for Debian. I write it for Debian’s Long Term Support sponsors but also for the wider free software community in the hope that it might inspire people to get more involved with Debian or free software in general.

Debian Android

Debian Games

  • I packaged CaveExpress and CavePacker for Debian. CaveExpress is a remake of the old Amiga classic Ugh! In this game you control a pedal-powered flying machine and pick up packages from your clients. An interesting aspect of CaveExpress is its physics-based gameplay. The packages must be delivered to a collection point and their movement is quite realistic thanks to the excellent Box2d physics engine. The other game, CavePacker, based on the same engine as CaveExpress is a Sokoban-like game. Both games feature dozens of levels and if you have nothing better to do, you should definitely check them out.
  • This month I also packaged a new upstream release of Netpanzer. Apparently there is new upstream activity.
  • Blockattack 2.0 was released and is now available in Debian.
  • I also updated the following packages: kball, pathogen, ceferino, slimevolley, pangzero and airstrike.
  • I adopted abe, berusky and berusky-data, updated the packages to use modern debian helpers and also packaged version 1.7 of berusky, a great Sokoban-like game by the way.
  • June also saw a new release of debian-games, several metapackages that make it much easier to install a subset of games or even the finest.
  • I sponsored RC-bug fixes for parsec47, tumiki-fighters, mu-cade and tatan all prepared by Peter De Wachter who keeps our D (yes, that’s a language) games alive. But we will face more issues in the post Stretch future. Apparently the D language people intend to remove parts of their API and of course all our D-based games are affected. Peter has announced more information about that. I think all these games are pretty unique and real gems. If you know a little D and want to help out, please get involved.

Debian Java

Debian LTS

This was my fifth month as a paid contributor and I have been paid to work 19,75 hours on Debian LTS. In that time I did the following:

  • DLA-501-1. Salvatore Bonaccorso from Debian’s Security Team discovered that the original fix for CVE-2015-7552 (DLA-450-1) was incomplete. I prepared and uploaded a new revision of gdk-pixbuf and issued the DLA.
  • DLA-502-1. Issued a security update for graphicsmagick fixing 1 CVE.
  • DLA-504-1. Issued a security update for libxstream-java fixing 1 CVE which was prepared by Emmanuel Bourg.
  • DLA-505-1. Issued a security update for libpdfbox-java fixing 1 CVE.
  • DLA-508-1. Issued a security update for expat fixing 2 CVE.
  • DLA-511-1. Issued a security update for libtorrent-rasterbar fixing 1 CVE.
  • DLA-526-1. Issued a security update for mysql-connector-java fixing 1 CVE. I also prepared the update for Jessie which is still pending to be reviewed by the Security Team.
  • DLA-528-1. Issued a security update for libcommons-fileupload-java fixing 1 CVE.
  • DLA-529-1. Issued a security update for tomcat7 fixing 1 CVE.
  • DLA-530-1. As previously announced I switched the default Java implementation from OpenJDK 6 to OpenJDK 7.
  • DLA-537-1. Issued a security update for roundcube fixing 1 CVE. I triaged CVE-2016-5103, CVE-2015-2180 and CVE-2015-2181 and marked them as „not-vulnerable“.
  • I triaged 22 CVEs for libarchive and marked two of them as „not-vulnerable“. You can find my preliminary work for libarchive on the wheezy branch in Debian’s git repository. I expect a security update very soon.
  • From 13 June to 19. June I was responsible for Wheezy’s LTS frontdesk. It was a rather calm week on the debian-lts mailing list and in our IRC channel. I triaged CVE-2016-4970 (netty), CVE-2016-3189 (bzip2), CVE-2016-1621 (libvpx) and CVE-2016-4493, CVE-2016-4492, CVE-2016-4491, CVE-2016-4490, CVE-2016-4489, CVE-2016-4488, CVE-2016-4487, CVE-2016-2226 which were all minor issues in developer tools or in the gcc toolchain.
  • I commented on Ola’s question about open security issues in phpmyadmin.

QA uploads

  • I fixed pygccxml that threatened to remove spring.
  • I completely overhauled gl-117, fixed four bugs and closed two obsolete ones. gl-117 always reminds me a little of the Falcon series from the early 90ies.
