Debian goes libjpeg-turbo 2.0.x [RFH]

I recently uploaded libjpeg-turbo 2.0.2-1~exp1 to Debian experimental. This has been the first upload of the 2.0.x release series of libjpeg-turbo.

After 3 further upload iterations (~exp4 that is), the package now builds on nearly all (except 3) architectures supported by Debian.

@all: Please Test

For those architectures that libjpeg-turbo 2.0.2-1~exp* is already available in Debian experimental, please start testing your applications on Debian testing/unstable systems with libjpeg-turbo 2.0.2-1~exp* installed from experimental. If you observe any peculiarities, please file bugs against src:libjpeg-turbo on Debian BTS. Thanks!

Please note: the major 2.x release series does not introduce an SOVERSION bump, so applications don't have to be rebuilt against the newer libjpeg-turbo. Simply drop-in-replace installed libjpeg62-turbo bin:pkg by the version from Debian experimental.

[RFH] FTBFS during Unit Tests

On the alphas, powerpc and sparc64 architectures, the builds [1] fail during unit tests:

301/302 Test #155: tjunittest-static-yuv-alloc .......................   Passed   60.08 sec
302/302 Test #156: tjunittest-static-yuv-nopad .......................

Kudos to the Rspamd developers

I just migrated the first / a customer's mail server site away from Amavis+SpamAssassin to Rspamd. Main reasons for the migration were speed and the setup needed a polish up anyway. People on site had been complaining about too much SPAM for quite a while. Plus, it is always good to dive into something new. Mission accomplished.

Implemented functionalities:

  • Sophos AV (savdi) antivirus checks backend
  • Clam AV antivirus backend as fallback
  • Auto-Learner CRON Job for SPAM mails published by https://artinvoice.hu
  • Work-around lacking http proxy support

Unfortunately, I could not enable the full scope of Rspamd features, as that specific site I worked on is on a private network, behind a firewall, etc. Some features don't make sense there (e.g. greylisting) or are hard-disabled in Rspamd once it detects that the mail host is on some local network infrastructure (local as in RFC-1918, or the corresponding fd00:: RFC for IPv6 I currently can't remember).

Kudos + Thanks!

Rspamd is just awesome!!! I am really really pleased with the result (and so is the customer, I heard). Thanks to the upstream developers, thanks to the Debian maintainers of the rspamd Debian package. [1]

Credits + Thanks for sharing your Work

The main part of the work had already been documented in a blog post [2] by someome with the nick "zac" (no real name found).

MATE 1.22 landed in Debian unstable

Last week, I did a bundle upload of (nearly) all MATE 1.22 related components to Debian unstable. Packages should have been built by now for most of the 24 architectures supported by Debian (I just fixed an FTBFS of mate-settings-daemon on non-Linux host archs). The current/latest build status can be viewed on the DDPO page of the Debian+Ubuntu MATE Packaging Team [1].

Credits

Again a big thanks goes to the packaging team and also to the upstream maintainers of the MATE desktop environment. Martin Wimpress and I worked on most parts of the packaging for the 1.22 release series this time. On the upstream side, a big thanks goes to all developers, esp. Vlad Orlov and Wolfgang Ulbrich for fixing / reviewing many many issues / merge requests. Good work, folks!!! plus Big Thanks!!!

My Work on Debian LTS/ELTS (July 2019)

In July 2019, I have worked on the Debian LTS project for 15.75 hours (of 18.5 hours planned) and on the Debian ELTS project for another 12 hours (as planned) as a paid contributor.

LTS Work

  • Upload to jessie-security: libssh2 (DLA 1730-3) [1]
  • Upload to jessie-security: libssh2 (DLA 1730-4) [2]
  • Upload to jessie-security: glib2.0 (DLA 1866-1) [3]
  • Upload to jessie-security: wpa (DLA 1867-1) [4]

The Debian Security package archive only has arch-any buildds attached, so source packages that build at least one arch-all bin:pkg must include the arch-all DEBs from a local build. So, ideally, we upload source + arch-all builds and leave the arch-any builds to the buildds. However, this seems to be problematic when doing the builds using sbuild. So, I spent a little time on...

  • sbuild: Try to understand the mechanism of building arch-all + source package (i.e. omit arch-any uploads)... Unfortunately, there is no "-g" option (like in dpkg-buildpackage). Neither does the parameter combination ''--source --arch-all --no-arch-any'' result in a source + arch-all build. More investigation / communication with the developers of sbuild required here. To be continued...

My Work on Debian LTS/ELTS (June 2019)

In June 2019, I did not at all reach my goal of LTS/ELTS hours, unfortunately. (At this point, I could come up with a long story about our dog'ish family member and the infection diseases he got, the vet visits we did and the daily care and attention he needed, but I won't...).

I have worked on the Debian LTS project for 9,75 hours (of 17 hours planned) and on the Debian ELTS project just for 1 hour (of 12 hours planned) as a paid contributor.

LTS Work

  • LTS: Setup physical box running Debian jessie (for qemu testing)
  • LTS: Bug hunting mupdf regarding my CVE-2018-5686 patch backport
  • LTS: Upload to jessie-security: mupdf (DLA-1838-1), 3 CVEs [1]
  • LTS: Glib2.0: request CVE Id (CVE-2019-13012) + email communication with upstream [2] (minor issue for Glib2.0 << 2.60)
  • LTS: cfengine3: triage CVE-2019-9929, email communication with upstream (helping out security team) [3]

ELTS Work

  • Upload to wheezy-lts: expat (ELA 136-1), 1 CVE [4]

List Open Files for a Running Application/Service

This is merely a little reminder for myself:

for pid in `ps -C <process-name> -o pid=`; do ls -l "/proc/$pid/fd"; done

On Linux, this returns a list of file handles being held open by all instances of <process-name>.

Update (2019-06-27): Martin Schuster suggested an even nicer (and regarding the output seemingly a more complete) approach to me by email:

lsof -c /^<process-name>$/ -a -d ^mem

My Work on Debian LTS/ELTS (May 2019)

  • Prepare a test-build for mupdf [5]. Testing still pending.
  • Triaging of open CVEs for 12 packages

Picnic in the Dead Zone

Today, I talked to Christoph. He is from a local, rather new intiative here in Nothern Germany:

     Picknick im Funkloch

(Picnic in the Dead Zone).

We discussed how DAS-NETZWERKTEAM (my FLOSS business) can support that initiative on the technical level (we will start with mailing lists).

The Picnic in the Dead Zone initiative aims at making people more aware of possible health and social consequences that may be caused by the upcoming 5G mobile standard reaching 90%-plus coverage.

Personally, I know individual people who are (highly) sensitive to electro-magnetic radiation and fields (they can tell you if wireless network is on or off, tell you which access point where in the house is on or off, can differentiate between WiFi and PoweLAN, etc.). For people with such a sensitivity it is crucial to have spots in the country they want to live in, where electro-magnetic radiation is at a minimum level. Mobile connectivity does not work for everyone. Hyper-sensitive people suffer from it, in fact.

@all-the-Germans: Currently, there is an ePetition waiting for (maybe your) signature(s) on the German Bundestag's ePetition home page. The signing deadline is pretty close: 4th April 2019.
