In my previous post I mentioned my involvement with the OpenRISC or1k port. It was the technical activity in which I spent most time during 2014 (Debian and otherwise, day job aside). I thought that it would be nice to talk a bit about the port for people who don't know about it, and give an update for those who do know and care. So this post explains a bit how it came to be, details about its development, and finally the current status. It is going to be written as a rather personal account, for that matter, since I did not get involved enough in the OpenRISC community at large to learn much about its internal workings and aspects that I was not directly involved with. There is not much information about all of this elsewhere, only bits and pieces scattered here and there, but specially not much public information at all about the development of the Debian port. There is an OpenRISC entry in the Debian wiki, but it does not contain much information yet. Hopefully, this piece will help a bit to preserve history and give an insight for future porters. First Things First I imagine that most people reading this post will be familiar with the terminology, but just in case, to create a new Debian port means to get a Debian system (GNU/Linux variant, in this case) to run in the OpenRISC or1k computer architecture. Setting to one side all differences between hardware and software, and as described in their site:

The aim of the OpenRISC project is to create free and open source computing platforms

It is therefore a good match for the purposes of Debian and Free Software world in general. The processor has not been produced in silicon, or not available for the masses in any case. People with the necessary know-how can download the hardware description (Verilog) and synthesise it in a FPGA, or otherwise use simulators. It is not some piece of hardware that people can purchase yet, and there are no plans to mass-produce it in the near future either. The two people (including me) involved in this Debian port did not have the hardware, so we created the port entirely through cross-compiling from other architectures, and then compiling inside Qemu. In a sense, we were creating a Debian port for hardware that "does not [phisically] exist". The software that we built was tested by people who had hardware available in FPGA, though, so it was at least usable. I understand that people working in the arm64 port had to work similarly in the initial phases, working in the dark without access to real hardware to compile or test. The Spark The first time that I heard about the initiative to create the port was in late February of 2014, in a post which appeared in Linux Weekly News (sent by Paul Wise) and Slashdot. The original post announcing it was actually from late January, from Christian Svensson (blueCmd):

Some people know that I've been working on porting Glibc and doing some toolchain work. My evil master plan was to make a Debian port, and today I'm a happy hacker indeed! Below is a link to a screencast of me installing Debian for OpenRISC, installing python2.7 via apt-get (which you shouldn't do in or1ksim, it takes ages! (but it works!)) and running a small Python script. http://asciinema.org/a/7362

So, now, what can a Debian Hacker do when reading this? (Even if one's Hackery Level is not that high, as it is my case). And well, How Hard Can It Be? I mean, Really? Well, in my own defence, I knew that the answer to the last two questions would be a resounding Very . But for some reason the idea grabbed me and I couldn't help but think that it would be a Really Exciting Project, and that somehow I would like to get involved. So I wrote to Christian offering my help after considering it for a few days, around mid March, and he welcomed me aboard. The Ball Was Already Rolling Christian had already been in contact with the people behind DebianBootstrap, and he had already created the repository http://openrisc.debian.net/ with many packages of the base system and beyond (read: packages name_version_or1k.deb available to download and install). Still nowadays the packages are not signed with proper keys, though, so use your judgement if you want to try them. After a few weeks, I got up to speed with the status of the project and got my system working with the necessary tools. This meant basically sbuild/schroot to compile new packages, with the base system that Christian already got working, installed in a chroot, probably with the help of debootstrap, and qemu-system-or1k to simulate the system. Only a few of the packages were different from the version in Debian, like gcc, binutils or glibc -- they had not been upstreamed yet. sbuild ran through qemu-system-or1k, so the compilation of new packages could happen "natively" (running inside Qemu) rather than cross-compiling the packages, pulling _or1k.deb packages for dependencies from the repository that he had prepared, and _all.deb packages from snapshots.debian.org. I started by trying to get the packages that I [co-]maintain in Debian compiled for this architecture, creating the corresponding _or1k.deb. For most of them, though, I needed many dependencies compiled before I could even compile my packages. The GNU autotools / autoreconf Problem Since very early, many of the packages failed to build with messages such as:

Invalid configuration 'or1k-linux-gnu': machine 'or1k' not recognized
configure: error: /bin/bash ../config.sub or1k-linux-gnu failed

This means that software packages based on GNU autotools and using configure scripts need recent versions of the files config.sub and config.guess that they ship in their root directory, to be able to detect the architecture and generate the code accordingly. This is counter-intuitive, having into account that GNU autotools were designed to help with portability. Yet, in the case of creating new Debian ports, it meant that unless upstream had very recent versions of config. guess,sub , it would prevent the package to compile straight away in the new architectures -- even if invoking gcc without ado would have worked without problems in most cases for native compilation. Of course this did not only affect or1k, and there was already the autoreconf effort underway as a way to update these files automatically when building Debian packages, pushed by people porting Debian to the new architectures added in 2013/2014 (mips64el, arm64, ppc64el), which encountered the same roadblock. This affected around a thousand source packages in unstable. A Royal Pain. Also, all of their reverse dependencies (packages that depended on those to be built) could not be compiled straight away. The bugs were not Release Critical, though (none of these architectures were officially accepted at the time), so for people not concerned with the new ports there was no big incentive to get them fixed. This problem, which conceptually is easily solvable, prevented new ports to even attempt compile vast portions of the archive straight away (cleanly, without modifications to the package or to the host system), for weeks or months. The GNU autotools / autoreconf Solution We tackled this problem mainly in two ways. First, more useful for Debian in general, was to do as other porters were doing and submit bug reports and patches to Debian packages requesting them to use autoreconf, and NMUing packages (uploading changes to the archive without the official maintainers' intervention). A few NMUs were made for packages which had bug reports with patches available for a while, that were in the critical path to get many other packages compiled, and that were orphan or had almost no maintainer activity. The people working in the other new ports, and mainly Ubuntu people which helped with some of those ports and wanted to support them, had submitted a large amount of requests since late 2013, so there was no shortage of NMUs to be made. Some porters, not being Debian Developers, could not easily get the changes applied; so I also helped a bit the porters of other architectures, specially later on before the freeze of Jessie, to get as many packages compiled in those architectures as possible. The second way was to create dpkg-buildpackage hooks that updated unconditionally config. guess,sub before attempting to build the package in the local build system. This local and temporary solution allowed us in the or1k port to get many _or1k.deb packages in the experimental repository, which in turn would allow many more packages to compile. After a few weeks, I set up many sbuilds in a multi-core machine attempting to build uninterruptedly packages that were not previously built and which had their dependencies available. Every now and then (typically several times per day in peak times) I pushed the resulting _or1k.deb files to the repository, so more packages would have the necessary dependencies ready to attempt to build. Christian was doing something similar, and by April at peak times, among the two of us, we were compiling some days more than a hundred packages -- a huge amount of packages did not need any change other than up-to-date config. guess,sub files. At some point, late April, Christian set up wanna-build in a few hosts to do this more elegantly and smartly than my method, and more effectively as well. Ugly Hacks, Bugs and Shortcomings in the Toolchain and Qemu Some packages are extremely important because many other packages need them to compile (like cmake, Qt or GTK+), and they are themselves very complex and have dependency loops. They had deeper problems than the autoreconf issue and needed some seriously dirty hacking to get them built. To try to get as many packages compiled as possible, we sometimes compiled these important packages with some functionality disabled, disabling some binary packages (e.g. Java bindings) or specially disabling documentation (using DEB_BUILD_OPTIONS=nodoc when possible, and more aggressively when needed by removing chunks of debian/rules). I tried to use the more aggressive methods in as few packages as possible, though, about a dozen in total. We also used DEB_BUILD_OPTIONS=nocheck for speeding up compilation and avoiding build failures -- many packages' tests failed due to qemu-system-or1k not supporting multi-threading, which we could do nothing about at the time, but otherwise the packages mostly passed tests fine. Due to bugs and shortcomings in Qemu and the toolchain --like the compiler lacking atomics, missing functionality in glibc, Qemu entering in endless loops, or programs segfaulting (especially gettext, used by many packages and causing the packages failing to build)--, we had to resort to some very creative ways or time-consuming dull work to edit debian/rules, or to create wrappers of the real programs avoiding or forcing certain options (like gcc -O0, since -O2 made buggy binaries too often). To avoid having a mix of cleanly compiled and hacked packages in the same repository, Christian set up a two-tiered repository system -- the clean one and the dirty one. In the dirty one we dumped all of the packages that we got built, no matter how. The packages in the clean one could use packages from the dirty one to build, but they themselves were compiled without any hackery. Of course this was not a completely airtight solution, since they could contain code injected at build time from the "dirty repository" (e.g. by static linking), and perhaps other quirks. We hoped to get rid of these problems later by rebuilding all packages against clean builds of all their dependencies. In addition, Christian also spent significant amounts of time working inside the OpenRISC community, debugging problems, testing and recompiling special versions of the toolchain that we could use to advance in our compilation of the whole archive. There were other people in the OpenRISC community implementing the necessary bits in the toolchain, but I don't know the details. Good Progress Olof Kindgren wrote the OpenRISC health report April 2014 (actually posted in May), explaining the status at the time of projects in the broad OpenRISC community, and talking about the software side, Debian port included. Sadly, I think that there have been no more "health reports" since then. There was also a new post in Slashdot entitled OpenRISC Gains Atomic Operations and Multicore Support shortly thereafter. In the side of the Debian port, from time to time new versions of packages entered unstable and we started to use those newer versions. Some of them had nice fixes, like the autoreconf updates, so they did not require local modifications. In other cases, the new versions failed to build when old ones had worked (e.g. because the newer versions added support and dependencies of new versions of gnutls, systemd or other packages not yet available for or1k), and we had to repeat or create more nasty hacks to get the packages built again. But in general, progress was very good. There were about 10k arch-dependent packages in Debian at the time, and we got about half of them compiled by the beginning of May, counting clean and dirty. And, if I recall correctly, there were around the same number of arch=all (which can be installed in any architecture, after the package is built in one of them). Counting both, it meant that systems using or1k got about 15k packages available, or 75% of the whole Debian archive (at least "main", we excluded "contrib" and "non-free"). Not bad. By the middle to end of May, we had about 6k arch-dependent packages compiled, and 4k to go. The count of packages eventually reached ~6.6k at its peak (I think that in June/July). Many had been built with hacks and not rebuilt cleanly yet, but everything was fine until the amount of packages built plateaued. Plateauing There were multiple reasons for that. One of them is that after having fixed the autoreconf issue locally in some packages, new versions were uploaded to Debian without fixing that problem (in many cases there was no bug report or patch yet, so it was understandable; in other cases the requests were ignored). The wanna-build for the clean repository set up by Christian rightly considered the package out-of-date and prepared to build the more recent version, that failed. Then, other packages entering the unstable archive and build-depending on newer versions of those could not be built ("BD-Uninstallable"), until we built the newer versions of the dependencies in the dirty repository with local hacks. Consequently, the count of cleanly built packages went back-and-forth, when not backwards. More challenging was the fact that when creating a new port, language compilers which are written in that same language need to be built for that architecture first. Sometimes it is not the compiler, but compile-time or run-time support for modules of a language are not ported yet. Obviously, as with other dependencies, large amounts of packages written in those languages are bound to remain uncompiled for a long time. As Colin Watson explained in porting Haskell's GHC to arm64 and ppc64el, untangling some of the chicken-and-egg problems of language compilers for new ports is extremely challenging. Perl and Python are pretty much a pre-requisite of the base Debian system, and Christian got them working early on. But for example in May, 247 packages depended on r-base-dev (GNU R) for building, and 736 on ghc, and we did not have these dependencies compiled. Just counting those two, 1k source packages of the remaining 4k to 5k to be compiled for the new architecture would have to wait for a long time. Then there was Java, Mono, etc... Even more worrying problems were the pending issues with the toolchain, like atomics in glibc, or make check failing for some packages in the clean repository built with wanna-build. Christian continued to work on the toolchain and liasing with the rest of the OpenRISC community, I continued to request more changes to the Debian archive through a few requests to use autoreconf, and pushing a few more NMUs. Though many requests were attended, I soon got negative replies/reactions and backed off a bit. In the meantime, the porters of other new architectures at the time were mostly submitting requests to support them and not NMUing much either. Upstreaming Things continued more or less in the same state until the end of the summer. The new ports needed as many packages built as possible before the evaluation of which official ports to accept (in early September, I think, the final decision around the time of the freeze). Porters of the other new architectures (and maintainers, and other helpful Debian Developers) were by then more active in pushing for changes, specially remaining autoreconf issues, many of which benefited or1k. As I said before, I also kept pushing NMUs now and then, specially during summer, for packages which were not of immediate benefit for our port but helped the others (e.g. ppc64el needed updates to ltmain.sh for libtool which were not necessary for or1k, in addition to config. guess,sub ). In parallel in the or1k camp, there were patches that needed changes to be sent upstream, like for example Python's NumPy, that I submitted in May to the Debian package and upstream, and was uploaded to Debian in September with a new upstream release. Similar paths were followed between May and September for packages such as jemalloc, ocaml, gstreamer0.10, libgc, mesa, X.org's cf module and cmake (patch created by Christian). In April, Christian had reached the amazing milestone of tracking and getting all of the contributors of the port of GNU binutils to assign copyright to the Free Software Foundation (FSF), all of the work was refreshed and upstreamed. In July or August, he started to gather information about the contributors of the GCC port, which had started more than a decade ago. After that, nothing much happened (from the outside) until the end of the year, when Christian sent a message about the status of upstreaming GCC to the OpenRISC community. There was only one remaining person to assign the copyright to the FSF, but it was a blocker. In addition, there was the need to find one or more maintainers to liaise with upstream, review the patches, fix the remaining failures in the test suite and keeping the port in good shape. A few months after that and from what I could gather, the status remains the same. Current Status, and The Future? In terms of the Debian port, there have not been huge visible changes since the end of the summer, and not only because of the Jessie freeze. It seems that for this effort to keep going forward and be sustainable, sorting out the issues with GCC and Glibc is essential. That means having the toolchain completely pushed upstream and in good shape, and particularly completing the copyright assignment. Debian will not accept private forks of those essential packages without a very good reason even in unofficially supported ports; and from the point of view of porters, working in the remaining not-yet-built packages with continuing problems in the toolchain is very frustrating and time-consuming. Other than that, there is already a significant amount of software available that could run in an or1k system, so I think that overall the project has achieved a significant amount of success. Granted, KDE and LibreOffice are not available yet, neither are the tools depending on Haskell or Java. But a lot of software is available (including things high in the stack, like XFCE), and in many aspects it should provide a much more functional system that the one available in Linux (or other free software) systems in the late 1990s. If the blocking issues are sorted out in the near future, the effort needed to get a very functional port, on par with the unofficial Debian ports, should not be that big. In my opinion, and looking at the big picture, not bad at all for an architecture whose hardware implementation is not easy to come by, and in which the port was created almost solely with simulators. That it has been possible to get this far with such meagre resources, it's an amazing feat of Free Software and Debian in particular. As for the future, time will tell, as usual. I will try to keep you posted if there is any significant change in the future.

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me. Debian LTS This month I have been paid to work 15.25 hours on Debian LTS. In that time I did the following:

• CVE triage: I pushed 37 commits to the security tracker and contacted 20 maintainers about security issues affecting their packages.
• I started a small helper script based on the new JSON output of the security tracker (see #761859 for details). It s not ready yet but will make it easier to detect issues where the LTS team lags behind the security team, and other divergences like this and will speed up future CVE triage work (once done).
• I sent DLA-174-1 (tcpdump update fixing 3 CVE) after having received a debdiff from the Romain Fran oise.
• I prepared DLA-175-1 on gnupg, fixing 3 CVE.
• I prepared DLA-180-1 on gnutls26, fixing 3 CVE.

That s it for the paid work. But still about LTS, I proposed two events for Debconf 15:

• Inner workings of an unusual team in Debian: the Long Term Support team: a generic presentation of the team and the project;
• Preparing for Wheezy LTS: a work session between the security team and the LTS team.

In my last Freexian LTS report, I mentioned briefly that it would be nice to have a logo for the LTS project. Shortly after I got a first logo prepared by Damien Escoffier and a few more followed: they are available on a wiki page (and the logo you see above is from him!). Following a suggestion of Paul Wise, I registered the logo request on another wiki page dedicated to artwork requests. That kind of collaboration is awesome! Thanks to all the artists involved in Debian. Debian packaging Django. This month has seen no less than 3 upstream point releases packaged for Debian (1.7.5, 1.7.6 and 1.7.7) and they have been accepted by the release team into Jessie. I m pleased with this tolerance as I have argued the case for it multiple times in the past given the sane upstream release policy (bugfix only in a given released branch). Python code analysis. I discovered a few months ago a tool combining the power of multiple Python code analysis tools: it s prospector. I just filed a Request for Package for it (see #781165) and someone already volunteered to package it, yay \o/ update-rc.d and systemd. While working on a Kali version based on Jessie, I got hit by what boils down to a poor interaction between systemd and update-rc.d (see #746580) and after some exchanges with other affected users I raised the severity to serious as we really ought to do something about it before release. I also opened #781155 on openbsd-inetd as its usage of inetd.service instead of openbsd-inetd.service (which is only provided as a symlink to the former) leads to multiple small issues. Misc Debian France. The general assembly is over and the new board elected its new president: it s now official, I m no longer Debian France s president. Good luck to Nicolas Dandrimont who took on this responsibility. Salt s openssh formula. I improved salt s openssh formula to make it possible to manage the /etc/ssh/ssh_known_hosts file referencing the public SSH keys of other managed minions. Tendenci.com. I was looking for a free software solution to handle membership management of a large NPO and I discovered Tendenci. It looked very interesting feature wise and written with a language/framework that I enjoy (Python/Django). But while it s free software, there s no community at all. The company that wrote it released it under a free software license and it really looks like that they did intend to build a community but they failed at it. When I looked their development forums were web-based and mostly empty with only initial discussion of the current developers and no reply from anybody there s also no mention of an IRC channel or a mailing list. I sent them a mail to see what kind of collaboration we could expect if we opted for their software and got no reply. A pity, really. What free software membership management solution would you use when you have more than 10000 members to handle and when you want to use the underlying database to offer SSO authentication to multiple external services? Thanks See you next month for a new summary of my activities.

I previously wrote about tracking a ship around the world, but never followed up with the practical details involved with shipping my life from the San Francisco Bay Area back to Belfast. So here they are, in the hope they provide a useful data point for anyone considering a similar move. Firstly, move out. I was in a one bedroom apartment in Fremont, CA. At the time I was leaving the US I didn t have anywhere for my belongs to go - the hope was I d be back in the Bay Area, but there was a reasonable chance I was going to end up in Belfast or somewhere in England. So on January 24th 2014 I had my all of my belongings moved out and put into storage, pending some information about where I might be longer term. When I say all of my belongings I mean that; I took 2 suitcases and everything else went into storage. That means all the furniture for probably a 2 bed apartment (I d moved out of somewhere a bit larger) - the US doesn t really seem to go in for the concept of a furnished lease the same way as the UK does. I had deliberately picked a moving company that could handle the move out, the storage and the (potential) shipping. They handed off to a 3rd party for the far end bit, but that was to be expected. Having only one contact to deal with throughout the process really helped. Fast forward 8 months and on September 21st I contacted my storage company to ask about getting some sort of rough shipping quote and timescales to Belfast. The estimate came back as around a 4-6 week shipping time, which was a lot faster than I was expecting. However it turned out this was the slow option. On October 27th (delay largely due to waiting for confirmation of when I d definitely have keys on the new place) I gave the go ahead. Container pickup (I ended up with exclusive use of a 20ft container - not quite full, but not worth part shipment) from the storage location was originally due on November 7th. Various delays at the Port of Oakland meant this didn t happen until November 17th. It then sat in Oakland until December 2nd. At that point the ETA into Southampton was January 8th. Various other delays, including a week off the coast of LA (yay West Coast Port Backups) meant that the ship finally arrived in Southampton on January 13th. It then had to get to Belfast and clear customs. On January 22nd 2015, 2 days shy of a year since I d seen them, my belongings and I were reunited. So, on the face of it, the actual time on the ship was only slightly over 6 weeks, but all of the extra bits meant that the total time from Ship it to I have it was nearly 3 months. Which to be honest is more like what I was expecting. The lesson: don t forget to factor in delays at every stage. The relocation cost in the region of US$8000. It was more than I d expected, but far cheaper than the cost of buying all my furniture again (plus the fact there were various things I couldn t easily replace that were in storage). That cost didn t cover the initial move into storage or the storage fees - it covered taking things out, packing them up for shipment and everything after that. Including delivery to a (UK) 3rd floor apartment at the far end and insurance. It s important to note that I d included this detail before shipment - the quote specifically mentioned it, which was useful when the local end tried to levy an additional charge for the 3rd floor aspect. They were fine once I showed them the quote as including that detail. Getting an entire apartment worth of things I hadn t seen in so long really did feel a bit like a second Christmas. I d forgotten a lot of the things I had, and it was lovely to basically get a home in a container delivered.

Today early in the morning my monitoring system notified me about unusual high outgoing traffic on my hosting plattform. I traced the problem down the webserver which is also hosting this abondened website. Looking into this with iptraf revealed that this traffic is coming only from one IP. At first I thought anybody might grabbing my Debian packages from ftp.cyconet.org. But no, it was targeting my highly sophisticated blogging plattform.

It makes me really sad to see, that dictionary attacks are smashing with such a high power these days, even without evaluating the 404 response.

I have just released version 1.9 of Obnam, my backup program. See the website at http://obnam.org for details. The new version is available from git (see http://git.liw.fi) and as Debian packages from http://code.liw.fi/debian. Due to the freeze of Debian for the jessie release, I've not uploaded this version to Debian yet (not experimental and not backports). This is the first Obnam release since May 13, 2014, 313 days ago. That's a long time. I make no excuses: Obnam is a hobby project, which I work on when I have the time and energy. The past year has been very /interesting/ year for me, in all sorts of stressful ways: I've changed jobs, moved to another country, and dealt with the loss of a close relative. Because of this, I've not been able to spend as much time on Obnam as I'd like. The NEWS file extract below gives the highlights of what has happened to Obnam during this time. There's been a lot of things, actually. My plans for Obnam next are mainly centered around performance. This will require developing a new repository format, to allow things that are not possible with the current format. For example, the current format stores each data chunk in its own file in the repository, and that is quite wasteful when live data files (and therefore their chunks) are quite small. As preparation for this work, the silly-looking "simple" format has been added, mostly to make sure the internal code infrastructure is ready to support multiple repository formats in the same Obnam version. Those interested in discussing ways to make Obnam fast should join the obnam-dev mailing list. Version 1.9, released 2015-03-22 New features:

• James Vasile changed Obnam so it can backup an individual file, instead of an entire directory.
• James Vasile added the --include option to Obnam, allowing one to include files that would otherwise be excluded (see --exclude).
• Carlo Teubner changed obnam fsck to remove unused chunks, if the --fsck-fix or --fsck-rm-unused settings are used. He also made it not check for unused chunks when it's useless to do so, because of various --fsck-skip settings are used.
• A start of a French translation of the manual by pedrito2.
• Ian Cambell provided a new Obnam command, obnam kdirstat, which makes the KDE k4dirstat utility be able to show graphically which parts of a backup generation use most space.
• Lars Wirzenius added the simple repository format, which is for demonstration only. It is much too simplistic to be used for real.

Minor changes:

• The manual page and obnam --help are now clearer that the --root setting and command line arguments to obnam backup can be SFTP URLs. Thanks to Simone Piccardi for reporting the issue.
• David Fries filled in the displayed file permission mode bits.
• Grammar and typo fixes for the obnam.1 manual page, from Jean Jordaan.
• Tom Chiverton suggested a clarification to the manual page for "obnam mount" to say that each generation is a subdirectory.
• David Fries changed restore to set the group ownership if possible even when not root. No warnings are issued if the attempt fails.
• Jan Niggemann added a little to the German translation of the Obnam manual.
• Lars Wirzenius added the path to the error message about a missing chunk (R43272X).
• Lars Wirzenius made the message at the end of a backup report more statistics about transfers during the backup.

Bug fixes:

• The Obnam SFTP plugin would loop infinitely if it lost the connection to the SSH server while creating a temporary file. Itamar Turner-Trauring provided a fix for this.
• Will Dyson fixed a bug about locking while removing checkpoint generations.
• Michel Alexandre Salim fixed a Python 2.6 compatibility problem in the unit tests (use of assertRaises as a context manager).
• Lars Kruse fixed a bug with backing up of overlapping backup roots (e.g., / and /boot), given a test case by Adrien Clerc.
• Thomas Eschenbacher fixed a bug in the format 6 repository code that would crash when there is an obscure problem and a B-tree code can't be found in the tree.
• Tom Chiverton pointed out that the manual page was using "obnam restore" instead of "obnam mount" in an example for "obnam mount".
• The yarn test suite now runs FUSE tests (obnam mount) when fusermount is available, rather than checking for membership in the group fuse. The latter is a Debianism (fixed in Debian jessie).
• Thomas Waldmann noticed that obnam verify didn't notice that a file had new data, when the modification time was the same. Obnam now notices this.
• Thomas Waldmann fixed many typos and minor bugs in the source code.
• Laurence Perkins reported that the Tahoe-LAFS SFTP server returned some stat fields as None. Fixed to change those to be 0 instead.
• Lars Wirzenius fixed double-downloading of chunks during restores.

Notice: There were several requests for me to more elaborate on my path to Debian and impact on life so here it is. It's going to be a bit long so anyone who isn't interested in my personal Debian journey should skip it. :) In 2007. I enrolled into Faculty of Mechanical Engineering (at first at Department of Industrial Management and later transfered to Department of Mechatronics - this was possible because first 3 semesters are same for both departments). By the end of same year I was finishing my tasks (consisting primarily of calculations, some small graphical designs and write-ups) when famous virus, called by users "RECYCLER", sent my Windows XP machine into oblivion. Not only it took control over machine and just spawned so many processes that system would crash itself, it actually deleted all from hard-disk before it killed the system entirely. I raged - my month old work, full of precise calculations and a lot of design details, was just gone. I started cursing which was always continued with weeping: "Why isn't there an OS that can whithstand all of viruses, even if it looks like old DOS!". At that time, my roommate was my cousin who had used Kubuntu in past and currently was having SUSE dual-booted on his laptop. He called me over, started talking about this thing called Linux and how it's different but de facto has no viruses. Well, show me this Linux and my thought was, it's probably so ancient and not used that it probably looks like from pre Windows 3.1 era, but when SUSE booted up it had so much more beautiful UI look (it was KDE, and compared to XP it looked like the most professional OS ever). So I was thrilled, installed openSUSE, found some rough edges (I knew immediately that my work with professional CAD systems will not be possible on Linux machines) but overall I was bought. After that he even talked to me about distros. Wait, WTF distros?! So, he showed me distrowatch.com. I was amazed. There is not only a better OS then Windows - there where dozens, hundreds of them. After some poking around I installed Debian KDE - and it felt great, working better then openSUSE but now I was as most newbies, on fire to try more distros. So I was going around with Fedora, Mandriva, CentOS, Ubuntu, Mint, PCLinuxOS and in beginning of 2008 I stumbled upon Debian docs which where talking about GNU and GNU Manifesto. To be clear, I was always as a high-school kid very much attached to idea of freedom but started loosing faith by faculty time (Internet was still not taking too much of time here, youth still spent most of the day outside). So the GNU Manifesto was really a big thing for me and Debian is a social bastion of freedom. Debian (now with GNOME2) was being installed on my machine. As all that hackerdom in Debian was around I started trying to dig up some code. I never ever read a book on coding (until this day I still didn't start and finish one) so after a few days I decided to code tetris in C++ with thought that I will finish it in two days at most (the feeling that you are powerful and very bright person) - I ended it after one month in much pain. So instead I learned about keeping Debian system going on, and exploring some new packages. I got thrilled over radiotray, slimvolley (even held a tournament in my dorm room), started helping on #debian, was very active in conversation with others about Debian and even installed it on few laptops (I became de facto technical support for users of those laptops :D ). Then came 2010 which with negative flow that came in second half of 2009, started to crush me badly. I was promised to go to Norway, getting my studies on robotics and professor lied (that same professor is still on faculty even after he was caught in big corruption scandal over buying robots - he bought 15 years old robots from UK, although he got money from Norway to buy new ones). My relationship came to hard end and had big emotional impact on me. I fell a year on faculty. My father stopped financing me and stopped talking to me. My depression came back. Alcohol took over me. I was drunk every day just not to feel anything. Then came the end of 2010, I somehow got to the information that DebConf will be in Banja Luka. WHAT?! DebConf in city where I live. I got into #debconf and in December 2010/January 2011 I became part of the famous "local local organizers". I was still getting hammered by alcohol but at least I was getting out of depression. IIRC I met Holger and Moray in May, had a great day (a drop of rakia that was too much for all of us) and by their way of behaving there was something strange. Beatiful but strange. Both were sending unique energy of liberty although I am not sure they were aware of it. Later, during DebConf I felt that energy from almost all Debian people, which I can't explain. I don't feel it today - not because it's not there, it's because I think I integrated so much into Debian community that it's now a natural feeling which people here, that are close to me are saying that they feel it when I talk about Debian. DebConf time in Banja Luka was awesome - firstly I met Phil Hands and Andrew McMillan which were a crazy team, local local team was working hard (I even threw up during the work in Banski Dvor because of all heat and probably not much of sleep due to excitement), met also crazy Mexican Gunnar (aren't all Mexicans crazy?), played Mao (never again, thank you), was hanging around smart but crazy people (love all) from which I must notice Nattie (a bastion of positive energy), Christian Perrier (which had coordinated our Serbian translation effort), Steve Langasek (which asked me to find physiotherapist for his co-worker Mathias Klose, IIRC), Zach (not at all important guy at that time), Luca Capello (who gifted me a swirl on my birthday) and so many others that this would be a post for itself just naming them. During DebConf it was also a bit of hard time - my grandfather died on 6th July and I couldn't attend the funeral so I was still having that sadness in my heart, and Darjan Prtic, a local team member that came from Vienna, committed suicide on my birthday (23 July). But DebConf as conference was great, but more importantly the Debian community felt like a family and Meike Reichle told me that it was. The night it finished, me and Vedran Novakovic cried. A lot. Even days after, I was getting up in the morning having the feeling I need something to do for DebConf. After a long time I felt alive. By the end of year, I adopted package from Clint Adams and Moray became my sponsor. In last quarter of 2011 and beginning of 2012, I (as part of LUG) held talks about Linux, had Linux installation in Computer Center for the first time ever, and installed Debian on more machines. Now fast forwarding with some details - I was also on DebConf13 in Switzerland, met some great new friends such as Tincho and Santiago (and many many more), Santiago was also my roommate in Portland on the previous DebConf. In Switzerland I had really great and awesome time. Year 2014 - I was also at DebConf14, maintain a bit more packages and have applied for DD, met some new friends among which I must put out Apollon Oikonomopoulos and Costas Drogos which friendship is already deep for such a short time and I already know that they are life-long friends. Also thanks to Steve Langasek, because without his help I wouldn't be in Portland with my family and he also gave me Arduino. :) 2015. - I am currently at my village residence, have a 5 years of working experince as developer due to Debian and still a lot to go, learn and do but my love towards Debian community is by magnitude bigger then when I thought I love it at most. I am also going through my personal evolution and people from Debian showed me to fight for what you care, so I plan to do so. I can't write all and name all the people that I met, and believe me when I say that I remember most and all of you impacted my life for which I am eternally grateful. Debian, and it's community effect literally saved my life, spring new energy into me and changed me for better. Debian social impact is far bigger then technical, and when you know that Debian is a bastion of technical excellence - you can maybe picture the greatness of Debian. Some of greatest minds are in Debian but most important isn't the sheer amount of knowledge but the enormous empathy. I just hope I can in future show to more people what Debian is and to find all lost souls as me to give them the hope, to show them that we can make world a better place and that everyone is capable to live and do what they love. P.S. I am still hoping and waiting to see Bdale writing a book about Debian's history to this day - in which I think many of us would admire the work done by project members, laugh about many situations and have fun reading a book about project that was having nothing to do but fail and yet it stands stronger then ever with roots deep into our minds.

My wife and I have been thinking of visiting the UK for awhile, and we re finally starting to make some plans. I would be grateful to anyone reading this that might have some time to make suggestions on places to go, things to do, etc. Here s a bit of background, if it helps. We have both traveled internationally before; this would actually be the first time either of us has visited another English-speaking country. We are content, and in fact would prefer, to venture outside the most popular touristy areas (though that doesn t mean we d want to miss something awesome just because it s popular.) We will have a little less than a week, most likely. That means staying on one area, or two at the most. Some other tidbits:

• I particularly enjoy old buildings: churches, castles, cathedrals. A 400-year-old country church off a dusty road would be as interesting to me as Westminster Abbey I d consider both awesome to see. Castles that are in a good state of repair would also be great. I d enjoy getting in the countryside as well.
• My wife would enjoy literary connections: anything related to Dickens, A. A. Milne, Jane Austen, C. S. Lewis, etc.
• Although I know London is full of amazing sights, and that is certainly one destination we re considering, I am also fine with things like Roman ruines in Wales, A. A. Milne s estate, country churches, sites in Scotland, etc.
• Ireland / Northern Ireland might be a possibility, but we are mainly focused on Great Britain so far.
• Would we be able to accomplish this without a car? I understand it is rather difficult for Americans to have to drive in the UK.
• Are there non-conventional lodging options such as bed and breakfasts that might let us get to know our hosts a little better?
• If it helps understand me better, some highlights from my past trips included the amazing feeling of stepping back in time at Marienkirche in L beck or the Museum in der Runden Ecke (a former Stasi building in Leipzig), exploring the old city of Rhodes, or becoming friends with a shop owner in Greece and attending an amateur radio club meeting with him.

Finally, we would probably not be able to go until September. Is that a reasonable time? Is part of September maybe less busy but still decent weather? Thanks for any advice!

The new release 0.11.5 of Rcpp just reached the CRAN network for GNU R, and a Debian package has also been be uploaded. Rcpp has become the most popular way of enhancing GNU R with C++ code. As of today, 345 packages on CRAN depend on Rcpp for making analyses go faster and further; BioConductor adds another 41 packages, and casual searches on GitHub suggests dozens mores. This release continues the 0.11.* release cycle, adding another large number of small bug fixes, polishes and enhancements. Since the previous release in January, we incorporated a number of pull requests and changes from several contributors. This time, JJ deserves a special mention as he is responsible for a metric ton of the changes listed below, making Rcpp Attributes even more awesome. As always, you can follow the development via the GitHub repo and particularly the Issue tickets and Pull Requests. And any discussions, questions, ... regarding Rcpp are always welcome at the rcpp-devel mailing list. See below for a detailed list of changes extracted from the NEWS file.

Changes in Rcpp version 0.11.5 (2015-03-04)

Changes in Rcpp API:

• An error handler for tinyformat was defined to prevent the assert() macro from spilling.
• The Rcpp::warning function was added as a wrapper for Rf_warning.
• The XPtr class was extended with new checked_get and release functions as well as improved behavior (throw an exception rather than crash) when a NULL external pointer is dereferenced.
• R code is evaluated within an R_toplevelExec block to prevent user interrupts from bypassing C++ destructors on the stack.
• The Rcpp::Environment constructor can now use a supplied parent environment.
• The Rcpp::Function constructor can now use a supplied environment or namespace.
• The attributes_hidden macro from R is used to shield internal functions; the R_ext/Visibility.h header is now included as well.
• A Rcpp::print function was added as a wrapper around Rf_PrintValue.

Changes in Rcpp Attributes:

• The pkg_types.h file is now included in RcppExports.cpp if it is present in either the inst/include or src.
• sourceCpp was modified to allow includes of local files (e.g. #include "foo.hpp"). Implementation files (.cc; .cpp) corresponding to local includes are also automatically built if they exist.
• The generated attributes code was simplified with respect to RNGScope and now uses RObject and its destructor rather than SEXP protect/unprotect.
• Support addition of the rng parameter in Rcpp::export to suppress the otherwise automatic inclusion of RNGScope in generated code.
• Attributes code was made more robust and can e.g. no longer recurse.
• Version 3.2 of the Rtools is now correctly detected as well.
• Allow 'R' to come immediately after '***' for defining embedded R code chunks in sourceCpp.
• The attributes vignette has been updated with documentation on new features added over the past several releases.

Changes in Rcpp tests:

• On Travis CI, all build dependencies are installed as binary .deb packages resulting in faster tests.

Thanks to CRANberries, you can also look at a diff to the previous release As always, even fuller details are on the Rcpp Changelog page and the Rcpp page which also leads to the downloads page, the browseable doxygen docs and zip files of doxygen output for the standard formats. A local directory has source and documentation too. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.

I am reminded by Gunnar's wonderful news that I have been very remiss in publishing my own. Mathilda Sophie Hands, our second daughter, was delivered on the 9th of January. Her arrival was a little more interesting than we'd have preferred (with Gunde being suddenly diagnosed with HELLP Syndrome), but all has turned out well, with Gunde bouncing back to health surprisingly quickly, and Mathilda going from very skinny to positively chubby in a few short weeks, so no harm done. Today Mathilda produced her first on-camera smile. It's lovely when they start smiling. It seems to signal that there's a proper little person beginning to take shape.

FTP assistant Processing the new queue got off the ground again. This month I marked 154 packages for accept and rejected 20 packages. Some emails I got were rather funny and people are very creative when trying to interpret the license of upstream. But hey, most of the time upstream has a reason to choose a specific wording. You can try to interpret those words, but don t waste your time. Better ask upstream about their intention and whether this fits into the world of Debian. It only sounds strange when upstream publishes their stuff under licenseA and wants to distribute their files under licenseB but insists on keeping the wording of licenseA. That s life! Squeeze LTS This was my eighth month that I did some work for the Squeeze LTS initiative, started by Raphael Hertzog at Freexian. This month I got assigned a workload of 14.5h and I spent these hours to upload new versions of:

• [DLA-145-2] php5 regression update
• [DLA 146-1] krb5 security update
• [DLA 150-1] unzip security update
• [DLA 151-1] libxml2 security update
• [DLA 162-1] e2fsprogs security update

For whatever reason, the DLA-145-2 didn t reach debian-lts-announce. As the listmaster didn t find any reason for this (at least the other emails all appeared), I think there has been some extraterrestrial influence ( The Truth Is Out There ). Anyway, I also worked on an upload for binutils, but one patch is a real 100kB-beast. Meanwhile I am down to only one regression in one source file, so I hope that there will be an upload in March. I also uploaded one DLA for libgtk2-perl ([DLA 161-1] libgtk2-perl security update although no LTS sponsor indicated any interest. Other packages I didn t do any work on other packages, but looking at the bug count, the number of bugs has increased. So, sorry, if you sent in a bug report and I didn t answer. It is not forgotten. Donations After adding some micro payment buttons to my blog in January, I already got a donation of 20 in February. I really appreciate this and I feel vindicated that my contributions to Debian are still useful.

Long story short, we put in a bid to host Debconf 16 in Cape Town, and we got it! Back at Debconf 12 (Nicaragua), many people asked me when we re hosting a Debconf in South Africa. I just laughed and said Who knows, maybe some day . During the conference I talked to Stefano Rivera (tumbleweed) who said that many people asked him too. We came to the conclusion that we d both really really want to do it but just didn t have enough time at that stage. I wanted to get to a point where I could take 6 months off for it and suggested that we prepare a bid for 2019. Stefano thought that this was quite funny, I think at some point we managed to get that estimate down to 2017-2018. That date crept back even more with great people like Allison Randal and Bernelle Verster joining our team, along with other locals Graham Inggs, Raoul Snyman, Adrianna Pi ska, Nigel Kukard, Simon Cross, Marc Welz, Neill Muller, Jan Groenewald, and our international mentors such as Nattie Mayer-Hutchings, Martin Krafft and Hannes von Haugwitz. Now, we re having that Debconf next year. It s almost hard to believe, not sure how I ll sleep tonight, we ve waited so long for this and we ve got a mountain of work ahead of us, but we ve got a strong team and I think Debconf 2016 attendees are in for a treat! Since I happened to live close to Montr al back in 2012, I supported the idea of a Debconf bid for Montr al first, and then for Cape Town afterwards. Little did I know then that the two cities would be the only two cities bidding against each other 3 years later. I think both cities are superb locations to host a Debconf, and I m supporting Montr al s bid for 2017. Want to get involved? We have a mailing list and IRC channel: #debconf16-capetown on oftc. Thanks again for all the great support from everyone involved so far!

Like each month, here comes a report about the work of paid contributors to Debian LTS. Individual reports In January, 48 work hours have been equally split among 4 paid contributors. Their reports are available:

• Ben Hutchings
• Holger Levsen
• Rapha l Hertzog
• Thorsten Alteholz

Evolution of the situation During the last month, the number of paid work hours has made a noticeable jump: we re now at 58 hours per month. At this rate, we would need 3 more months to reach our minimal goal of funding the equivalent of a half-time position. Unfortunately, the number of new sponsors actually in the process is not likely to be enough to have a similar raise next month. So, as usual, we are looking for more sponsors. In terms of security updates waiting to be handled, the situation looks a bit worse than last month: the dla-needed.txt file lists 37 packages awaiting an update (7 more than last month), the list of open vulnerabilities in Squeeze shows about 63 affected packages in total (7 more than last month). The increase is not too worrying, but the waiting time before an issue is dealt with is sometimes more problematic. To be able to deal with all incoming issues in a timely manner, the LTS team needs more resources: some months will have more issues than usual, some issues will be longer to handle than others, etc. Thanks to our sponsors The new sponsors of the month are in bold.

• Gold sponsors:

This was my second month working on Debian LTS, paid for by Freexian's Debian LTS initiative via Codethink. I spent 11.75 hours working on the kernel package (linux-2.6) and committed my changes but did not complete an update. I or another developer will probably release an update soon. I have committed fixes for CVE-2013-6885, CVE-2014-7822, CVE-2014-8133, CVE-2014-8134, CVE-2014-8160 CVE-2014-9419, CVE-2014-9420, CVE-2014-9584, CVE-2014-9585 and CVE-2015-1421. In the process of looking at CVE-2014-9419, I noticed that Linux 2.6.32.y is missing a series of fixes to FPU/MMX/SSE/AVX state management that were made in Linux 3.3 and backported to 3.2.y some time ago. These addressed possible corruption of these registers when switching tasks, although it's less likely to happen in 2.6.32.y. The fix for CVE-2014-9419 depends on them. So I've backported and committed all these changes, but may yet decide that they're too risky to include in the next update.

My LTS January It was very nice to hear many appreciations for our work on Squeeze LTS during the last weekend at FOSDEM. People really seem to like and use LTS a lot - and start to rely on it. I was approached more than once about Wheezy LTS already... (Most of my FOSDEM time I spent with reproducible builds however, though this shall be the topic of another report, coming hopefully soon.) So, about LTS. First I'd like to describe some current practices clearly:

• the Squeeze LTS team might fix your package without telling the maintainers in advance nor directly: dak will send a mail as usual, but that might be the only notification you'll get. (Plus the DLA send out to the debian-lts-announce mailing list.)
• when we fix a package we will likely not push these changes into whatever VCS is used for packaging. So when you start working on an update (which is great), please check whether there has been an update before. (We don't do this because we are mean, but because we normally don't have commit access to your VCS...
• we totally appreciate help from maintainers and everybody else too. We just don't expect it, so we don't go and ask each time there is a DLA to be made. Please do support us & please do talk to us!

I hope this clarifies things. And as usual, things are open for discussion and best practices will change over time. In January 2014 I spent 12h on Debian LTS work and managed to get four DLAs released, plus I've marked some CVEs as not affecting squeeze. The DLAs I released were:

• DLA 139-1 for eglibc fixing CVE-2015-0235 also known as the "Ghost" vulnerability. The update itself was simple, testing needed some more attention but then there were also many many user requests asking about the update, and some were providing fixes too. And then many people were happy, though one person seriously complained at FOSDEM that the squeeze update was released full six hours after the wheezy update. I think I didn't really reply to that complaint, though obviously this person was right
• DLA 140-1 for rpm was quite straightforward to do, thanks to RedHat unsurprisingly providing patches for many rpm releases. There was just a lots of unfuzzying to do...
• DLA 141-1 for libksba had an easy to pick git commit in upstreams repo too, except that I had to disable the testsuite, but given the patch is 100% trivial I decided that was a safe thing to do.
• DLA 142-1 for privoxy was a bit more annoying, despite clearly available patches from the maintainers upload to sid: first, I had to convert them from quilt to dpatch format, then I found that 2 ouf 6 CVEs were not affecting the squeeze version as the code ain't present and then I spent almost an hour in total to find+fix 10 whitespace difference in 3 patches. At least there was one patch which needed some more serious changes

Thanks to everyone who is supporting Squeeze LTS in whatever form! We like to hear from you, we love your contributions, but it's also totally ok to silently enjoy a good old quality distribution Finally, something for the future: checking for previous DLAs is currently best done via said mailing list archive, as DLAs are not yet integrated into the website due to a dependency loop of blocking bugs... see #761945 for a starting point.

Uploaded python-q-text-as-data to Sid (new awesome package!)
Uploaded Horizon with some triggers mechanisms to start the compress when one of its JS depends is updated. That s very important for security!
Uploaded a fixed version of heat-cfntools to Sid (it was missing the /usr/lib/python* folder). Asked the release team for an unblock so it can reach Jessie.
Fixed unit tests in fuel-nailgun, thanks to a patch from Sebastian Kalinowski. Now all unit tests are passing but one (for which I opened a launchpad bug: tests are trying to write in /var/log/nailgun, which is impossible at package build time). Wednesday 03:

Uploaded glance, neutron, nova, designate, keystone, heat, trove to Sid, so that all sysv-rc init scripts are fixed with the new openstack-pkg-tools 21. Designate, heat, keystone and trove contains other minor fixes reported to the Debian BTS. Wednesday 07:
Asked the Debian release team (open bugs with debdiff as attachment) for unblocks of glance, neutron, nova, designate, keystone, heat, trove so they migrate to Jessie.
Fixed a few minor issues tracked in the Debian BTS on various packages. Thesday 08:
James Page from Canonical informed me that they are now using openstack-pkg-tools for maintaining their daemons in Nova, Cinder and Keystone in Ubuntu. That s an awesome news : more QA for both platforms.
James Page found out that dh_installinit *must* be called *after* the call of dh_systemd_enable, otherwise, daemons aren t started automatically at the first install of packages, as the unmask of systemd happens after the invoke-rc.d. Friday 09:
Did some QA checks on the latest upload. Fixed Heat which broke because using the wrong template name (glance instead of heat). Monday 12:
Started re-running the automated openstack-deploy scrip in Icehouse, Juno and Kilo. Found out the issue in Keystone wasn t fixed in Juno (but was fixed in other releases), and fixed it.
Removed the use of ssl.PROTOCOL_SSLv3 from heat (removed form Debian). Uploaded the fixed package to Sid.
All of openstack-deploy (debian/kilo branch) now works and succesfully installs OpenStack again. If dh_installinit is called before, we have:

# Automatically added by dh_installinit
if [ -x "/etc/init.d/keystone" ]; then
update-rc.d keystone defaults >/dev/null
fi
if [ -x "/etc/init.d/keystone" ]   [ -e "/etc/init/keystone.conf" ]; then
invoke-rc.d keystone start   true
fi
# End automatically added section
# Automatically added by dh_systemd_enable
# This will only remove masks created by d-s-h on package removal.
deb-systemd-helper unmask keystone.service >/dev/null   true
# was-enabled defaults to true, so new installations run enable.
if deb-systemd-helper --quiet was-enabled keystone.service; then
# Enables the unit on first installation, creates new
# symlinks on upgrades if the unit file has changed.
deb-systemd-helper enable keystone.service >/dev/null   true
else
# Update the statefile to add new symlinks (if any), which need to be
# cleaned up on purge. Also remove old symlinks.
deb-systemd-helper update-state keystone.service >/dev/null   true
fi
# End automatically added section

If it s called after dh_systemd_enable, we have:

# Automatically added by dh_systemd_enable
# This will only remove masks created by d-s-h on package removal.
deb-systemd-helper unmask keystone.service >/dev/null   true
# was-enabled defaults to true, so new installations run enable.

else
# Update the statefile to add new symlinks (if any), which need to be
# cleaned up on purge. Also remove old symlinks.
deb-systemd-helper update-state keystone.service >/dev/null   true

if [ -x "/etc/init.d/keystone" ]   [ -e "/etc/init/keystone.conf" ]; then
invoke-rc.d keystone start   true
fi
# End automatically added section

As a consequence, I have to re-upload version 22 of openstack-pkg-tools and also re-upload all OpenStack core packages to Debian Sid. Fixed a number of issues like:
* dbc_upgrade = true check which shouldn t have been there in postinst.
* <project>/configure_db default value is now always false
* db_sync and pkgos_dbc_postinst are now only done if <project>/configure_db is set to true.
Rebuilt all packages in Juno and Kilo with the above changes. Tuesday 13:
Opened unblock bugs for the release team to unblock all fixed packages.
Made more tests in Juno and Kilo to make sure the fixed bugs in Icehouse are fixed there too.
Fixed numerous issues in Trove (missing trove-conductor.conf, wrong trove-api init file, etc.). More work will be needed for it for both Icehouse and newer releases. Wednesday 14:
Did a doc meeting about debconf. Some doc contributors still want to kill the debconf / debian manual, and I have to not agree.
Made a new patch to better document the keystone install procedure:
Did some bug triaging in the doc about Debian.
Uploaded new versions of core packages to Experimental (eg: Juno) built against openstack-pkg-tools >= 22~, and some fixes forward ported from Icehouse: Keystone, Ceilometer, Cinder, Glance, Heat, Ironic, Murano, Neutron, Nova, Saraha and Murano-agent. All where rebuilt in Juno (Wheezy + Trusty) and Kilo (Jessie only) on my Jenkins. Thuesday 15:
Succesfully booted a live-build Debian live image containing mcollective and nailgun-agent as a Debian replacement for the hardware discovery / boostrap image of Fuel. Now, I need to find a way to use just a kernel + initramfs Friday 16 to Tuesday 20:
Worked on the packaging CI. Wednesday 21:
Fixed https://bugs.debian.org/775636 (Horizon failed to build due to a Moscow timezone change and wrong test). Uploaded to Sid, asked for unblock.
Fixed https://bugs.debian.org/775926: CVE-2015-1195: Glance still allows users to download and delete any file in glance-api server (applied upstream patch). Uploaded to Sid, asked for unblock. Uploaded Juno version to Experimental.
Uploaded openstack-trove with the remaining fixes, asked release team for unblock.
Uploaded python-glanceclient 0.15.0 (Juno) to Experimental because it fixes an issue with HTTPS. Added to it a patch from James Page not yet merged, which fixes unit test with Python 2.7.9 (7 failures otherwise).
Uploaded python-xstatic-d3 as it can t be installed anymore in Sid after a new version of d3 was uploaded. Thursday 22:
Uploaded python-xstatic-smart-table and libjs-angularjs-smart-table to Sid (new packages, now in NEW queue). Friday 23:

libjs-twitter-bootstrap-wizard They are used only in OpenStack Horizon starting on 2014.2 (aka Juno), and Jessie is shipped with Icehouse, so it s IMO best to not carry the burden of maintaining these packages for the life of Jessie. Monday 26:
Enhanced and review requested changes for https://review.openstack.org/147296 (ie: Keystone install with more details about what the package does).
Finished testing network on the CI install. Now need to automate all. Tuesday 27:
Closed all bugs on the rabbitmq-server package (2 correction, one bug triage).

Fixed the image-guide patch after review (ie: https://review.openstack.org/151015)

FTP assistant This month at the beginning of the year has been rather quiet as well. All in all I marked 50 packages for accept and rejected only 17 packages. Squeeze LTS This was my seventh month that I did some work for the Squeeze LTS initiative, started by Raphael Hertzog at Freexian. This month I got assigned a workload of 12h and I spent these hours to upload new versions of:

• [DLA 127-1] pyyaml security update
• [DLA 128-1] sox security update
• [DLA 138-1] jasper security update
• [DLA 145-1] php5 security update

In doing so, preparing the upload for php5 consumed most of the time as support from Upstream for the old version in Squeeze no longer exists. Oddly enough, a simple one-line-patch seems to have created a regression I also sponsored the upload of [DLA 133-1] unrtf security update, [DLA 134-1] curl security update and [DLA 130-1] firebird2.1 security update. Many thanks to Nguyen Cong from Toshiba who prepared the patches for these packages. I also uploaded two DLAs for polarssel ([DLA 129-1] polarssl security update and [DLA 144-1] polarssl security update) although no LTS sponsor indicated any interest. Other packages Thanks to the relentless QA work of Andreas Beckmann, his piuparts tests detected an issue in the greylistd package. If greylistd has been installed in Wheezy, removed but not purged afterwards, the whole system dist-upgraded to Jessie and afterwards greylistd is installed again, there would be an error message. RC bug taken, fixed package uploaded and unblock request approved.

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me. Debian LTS This month I have been paid to work 12 hours on Debian LTS. I did the following tasks:

• CVE triage. I pushed 24 commits to the securitry tracker. I spent more time on this task than usually (see details below).
• I released DLA-143-1 on python-django (fixing 3 CVE). While I expected the update to be quick, my testing revealed that even though the patches applied mostly fine, they did not work as expected. I ended up spending almost 4 hours to properly backport the fixes and the corresponding tests (to ensure that the fixes are working properly).

I want to expand on two cases that I stumbled upon in my CVE triage work and that took quite long to investigate each. While my after-the-fact description is rather straightforward, the real process involved more iterations and data gathering that I do not mention here. First I was investigating CVE-2012-6685 on libnokogiri-ruby and the upstream bug discussion revealed that libxml2 could also be part of the problem. Using the tests cases submitted there, I confirmed that libxml2 was also affected by an issue of its own then I started to analyze the history of CVE of libxml2 to find out whether that issue got a CVE assigned: yes, that was CVE-2014-0191 (although the CVE description is unrelated). But this CVE was marked as fixed in all releases. Why? It turns out that the upstream fix for this CVE is just the complement of another commit that was merged way earlier (and that was used as a basis for the commit as the copy/paste of the comment shows). When the security teams integrated the upstream patch in wheezy/squeeze, they were probably not aware that a full fix required to also include something else. In the end, I thus reopened CVE-2014-0191 on our tracker (commit here). The second problematic case was pound. Thijs Kinkhorst added pound related data on the multiple (high profile) SSL related issues. So it appeared on my radar of new vulnerable package in Squeeze because it was marked that CVE-2009-3555 was fixed in version 2.6-2 while Squeeze has 2.5-1. There was no bug reference in the security tracker and the Debian changelog for that version only mentioned an anti_beast patch which is yet another issue (CVE-2011-3389). I had to dig a bit deeper in the end I discovered that the above patch also has provisions for the CVE that was of interest to me, except that Brian May recently reported in #765649 that the package was still vulnerable to this issue I tried to understand where the above patch was failing and thus submitted my findings to the bug. And I updated the tracker data with my newly gained knowledge (commit 31751 and 31752). Tryton For me, January is always the month where I try to close the accounting books of Freexian. This year is no exception except that it s the first year where I do this with Tryton. I first upgraded to Tryton 3.4 to have the latest version. Despite this I discovered multiple problems while doing so since I don t want to have those problems next year, I reported them and prepared fixes for those related to the French chart of accounts:

• #4464: CSV export on tree views is unusable
• #4466: add missing deferral properties on accounts
• #4468: drop abusive reconcile properties on some accounts
• #4469: convert account 6354 into a real non-view account
• #4479: balance non-deferral accounts is broken with non-view parent accounts

Saltstack I mentioned this idea last month setting up and maintaining a lot of sbuild chroots can be tiresome so I wanted to automate this as much as possible. To achieve this I created three Salt formulas and got them added to the official Saltstack repository:

• debootstrap-formula
• schroot-formula
• sbuild-formula

Each one builds on top of the former. debootstrap-formula creates chroots with debootstrap or cdebootstrap. schroot-formula does the same and registers those chroots in schroot. And sbuild-formula does the same as schroot-formula but with different defaults that are more suited to sbuild chroots (and obviously ensures that sbuild is installed and that generated chroots are buildd chroots). With the sbuild formula I can put this in pillar data:

sbuild:
  chroots:
    wheezy:
      architectures: [amd64, i386]
      extra_dists:
        - wheezy-backports
        - wheezy-security
      extra_aliases:
        - wheezy-backports
        - stable-security
        - wheezy-security
    jessie:
    [...]

And then a simple salt-call state.highstate (I m running in standalone mode) will ensure that I have all the chroots properly setup. Misc packaging I packaged new upstream releases of Django in experimental and opened a pre-approval request to get the latest 1.7.x in jessie (#775892). It seems to be a difficult sell for the release team, which is a pity because we have active Debian developers, active upstream developers, and everybody is well aware of the no-new features rule to avoid regressions. Where is the risk? I also filed an unblock request for Dolibarr (on the request of the security team which wants to see the CVE fix reach Jessie). I did small contributions to two bugs that were of special interest to some of my donators (#751339 and #774811), they were not under my responsibility but I tried to get them moving by pinging the relevant people. I prepared a security upload for Django in Wheezy (python-django_1.4.5-1+deb7u9) and sent it to the security team. While doing this I discovered a small problem in their backported patch that I reported upstream in Django s ticket #24239. Debian France With the new year, it s again time to organize a general assembly with the election of a third of its board. So we solicited candidacies among the members and I m pleased to see that we got 6 candidacies for the 3 seats. It s a good sign that we still have enough persons caring about the association. One of them is even speaking of Debconf 17 in France great plans! On my side, I announced that I would not candidate to be president for the next year. I will stay on the board though to ensure we have a smooth transition. Thanks See you next month for a new summary of my activities.

I install the unattended-upgrades package on almost all of my Debian and Ubuntu servers in order to ensure that security updates are automatically applied. It works quite well except that I still need to login manually to upgrade my Rackspace servers whenever a new rackspace-monitoring-agent is released because it comes from a separate repository that's not covered by unattended-upgrades. It turns out that unattended-upgrades can be configured to automatically upgrade packages outside of the standard security repositories but it's not very well documented and the few relevant answers you can find online are still using the old whitelist syntax.

Initial setup The first thing to do is to install the package if it's not already done:

apt-get install unattended-upgrades

and to answer yes to the automatic stable update question. If you don't see the question (because your debconf threshold is too low -- change it with dpkg-reconfigure debconf), you can always trigger the question manually:

dpkg-reconfigure -plow unattended-upgrades

Once you've got that installed, the configuration file you need to look at is /etc/apt/apt.conf.d/50unattended-upgrades.

Whitelist matching criteria Looking at the unattended-upgrades source code, I found the list of things that can be used to match on in the whitelist:

• origin (shortcut: o)
• label (shortcut: l)
• archive (shortcut: a)
• suite (which is the same as archive)
• component (shortcut: c)
• site (no shortcut)

You can find the value for each of these fields in the appropriate _Release file under /var/lib/apt/lists/. Note that the value of site is the hostname of the package repository, also present in the first part these *_Release filenames (stable.packages.cloudmonitoring.rackspace.com in the example below). In my case, I was looking at the following inside /var/lib/apt/lists/stable.packages.cloudmonitoring.rackspace.com_debian-wheezy-x86%5f64_dists_cloudmonitoring_Release:

Origin: Rackspace
Codename: cloudmonitoring
Date: Fri, 23 Jan 2015 18:58:49 UTC
Architectures: i386 amd64
Components: main
...

which means that, in addition to site, the only things I could match on were origin and component since there are no Suite or Label fields in the Release file. This is the line I ended up adding to my /etc/apt/apt.conf.d/50unattended-upgrades:

 Unattended-Upgrade::Origins-Pattern  
         // Archive or Suite based matching:
         // Note that this will silently match a different release after
         // migration to the specified archive (e.g. testing becomes the
         // new stable).
 //      "o=Debian,a=stable";
 //      "o=Debian,a=stable-updates";
 //      "o=Debian,a=proposed-updates";
         "origin=Debian,archive=stable,label=Debian-Security";
         "origin=Debian,archive=oldstable,label=Debian-Security";
+        "origin=Rackspace,component=main";
  ;

Testing To ensure that the config is right and that unattended-upgrades will pick up rackspace-monitoring-agent the next time it runs, I used:

unattended-upgrade --dry-run --debug

which should output something like this:

Initial blacklisted packages: 
Starting unattended upgrades script
Allowed origins are: ['origin=Debian,archive=stable,label=Debian-Security', 'origin=Debian,archive=oldstable,label=Debian-Security', 'origin=Rackspace,component=main']
Checking: rackspace-monitoring-agent (["<Origin component:'main' archive:'' origin:'Rackspace' label:'' site:'stable.packages.cloudmonitoring.rackspace.com' isTrusted:True>"])
pkgs that look like they should be upgraded: rackspace-monitoring-agent
...
Option --dry-run given, *not* performing real actions
Packages that are upgraded: rackspace-monitoring-agent

Making sure that automatic updates are happening In order to make sure that all of this is working and that updates are actually happening, I always install apticron on all of the servers I maintain. It runs once a day and emails me a list of packages that need to be updated and it keeps doing that until the system is fully up-to-date. The only thing missing from this is getting a reminder whenever a package update (usually the kernel) requires a reboot to take effect. That's where the update-notifier-common package comes in. Because that package will add a hook that will create the /var/run/reboot-required file whenever a kernel update has been installed, all you need to do is create a cronjob like this in /etc/cron.daily/reboot-required:

#!/bin/sh
cat /var/run/reboot-required 2> /dev/null   true

assuming of course that you are already receiving emails sent to the root user (if not, add the appropriate alias in /etc/aliases and run newaliases).
