  • Linux 4.0 ate my docker images

    I have previously written about the gitlab CI runners that use docker.  Yesterday I made some changes to procps and pushed them to gitlab which would then start the CI.  This morning I checked and it said build failed – ok, so that’s not terribly unusual. The output from the runner was:

    gitlab-ci-multi-runner 0.3.3 (dbaf96f)
Using Docker executor with image csmall/testdebian ...
Pulling docker image csmall/testdebian ...
Build failed with Error: image csmall/testdebian: not found

    Hmm, I know I have that image, it just must be the runner so, let’s see what images I have:

    $ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE

    Now, I know I have images, I had about 10 or so of them, where did they go? I even looked in the /var/lib/docker directories and can see the json configs, what have you done with my images docker?

  • Debian, WordPress and Multi-site

    For quite some time, the Debian version of WordPress has had a configuration tweak that made it possible to run multiple websites on the same server. This came from a while ago when multi-site wasn’t available. While a useful feature, it does make the initial setup of WordPress for simple sites more complicated.

    I’m looking at changing the Debian package slightly so that for a single-site use it Just Works. I have also looked into the way WordPress handles the content, especially themes and plugins, to see if there is a way of updating them through the website itself. This probably won’t suit everyone but I think its a better default.

  • procps using GitLab CI

    procps-ciThe procps project for a few years has been hosted at Gitorious.  With the announcement that Gitorious has been acquired by GitLab and that all repositories need to move there, procps moved along to GitLab. At first I thought it would just be a like for like thing, but then I noticed that GitLab has this GitLab CI feature and had to try it out.

    CI here stands for Continuous Integration and is a way of automatically testing your program builds using a bunch of test scripts.  procps already has a set of tests, with some a level of coverage that has room for improvement, so it was a good candidate to use for CI. The way GitLab works is they have a central control point that is linked to the git repo and you create runners, which are the systems that actually compile the programs and run the tests. The runners then feed back their results and GitLab CI shows it all in pretty red or green.

  • Mudlet 3 beta

    Mudlet - Graphical MUD client

    A break from wordpress, I was trying to get the beta version of mudlet 3.0 compiling. On the surface the program looks a lot like the existing v2.0 that is currently within Debian.  The developers have switched from qt4 to qt5 which means a lot of dependency fun for me but I got there in the end.

    As it is only a beta and not their final release, the package is located within the Debian experimental release. Once 3.0 hits a final release, I’ll switch it to sid.  If you do use the current mudlet, give 3.0 a try. I’d be interested to know what you think.

  • WordPress 4.1 for Debian

    Release 4.1 of WordPress came out on Friday so after some work to fit in with the Debian standards, the Debian package 4.1-1 of WordPress will be uploaded shortly.  WordPress have also updated their themes with a 14-day early theme called twentyfifteen.  This is the default theme for WordPress 4.1 on-wards.

  • WordPress 4.0.1 fixes for Debian stable

    Previously I posted a short article about the WordPress package for Debian and how that SID was getting the updated WordPress 4.0.1 which had some security fixes.

    The question a lot of people were asking was: What about stable (or Wheezy).  After way too much time due to other pressing issues, I have just uploaded the patched WordPress debian package for stable.  The fixed version has the catchy number of 3.6.1~deb7u5.  This package has all of the relevant patches that went in from WordPress 3.7.4 to 3.7.5 and there are even CVE IDs for this package (and 4.0.1 which all this stems from).

  • WordPress 4.0.1 for Debian

    WordPress recently released an update that had multiple security patches for their (then) current version 4.0. This release is 4.0.1 and includes important security fixes.  The Debian packages got just uploaded, if you are running the Debian packaged wordpress, you should update to 4.0.1+dfsg-1 or later.

    I am going to look at these patches and see if they can and need to be backported to wordpress 3.6.1. Unfortunately I believe they will be. I’m also asking it to be unblocked into Jessie as it is a security fix.

    There was, at the time of writing, no CVE numbers.

  • IPv6 and bridges

    I’ve reported a bug on bridge-utils, but perhaps someone has already seen this and has a fix. My virtual IPv6 machines often lose connectivity from time to time. Tracking this down, it seems that the router sends Neighbor Solicitations (IPv6 ARPs basically). The physical interface of the bridge group receives it, but the vnet0 one does not.

    Using tshark I can see the pings on vnet0 but on br0 and eth1 I see the ping requests and the NS packets. So there is something odd going on with the bridge interface.

    If I remove and add the vnet0 interface from the bridge group, the connectivity comes back.

  • WordPress 4.0 for Debian

    Yesterday WordPress released version 4.0 or “Benny” of WordPress. I have now downloaded it and packed up for Debian users. The files just hit the ftp-master a few minutes ago and will then be distributed out to the various Debian mirrors.

    The upgrade should go smoothly but you will probably need to upgrade the twentytwelve/twentyfourteen themes if you have them installed. It seems release 4.0 they also updated these themes.

    My next Debian task for wordpress is to re-examine the permissions and locations of wp-content to see if we can have something that permits online updates of the plugins and themes but is still FHS compliant. I’ve also had some people report they have some installation problems, mainly around configuration and directories so let’s see if that can get fixed too.

  • WordPress 3.9.2 for Debian

    WordPress released today a security release 3.9.2 which they fix several security issues, including a denial of service issue around XML.  The corresponding Debian package 3.9.2+dfsg-1 is currently being uploaded to the Debian ftp-master server as I write this and should be available on the mirrors soon.

    Unfortunately at the time of writing, there are no CVE identifiers to match these problems up with, but refer to the wordpress page for details about these bugs.

    Andrew Nacin from WordPress has kindly outlined what versions are susceptible and it looks like the Debian squeeze (3.6.1+dfsg-1~deb6u4)  and wheezy (3.6.1+dfsg-1~deb7u3) are vulnerable to at least some of these bugs which means for me its patch reading and back-porting time
