Cross Compilation to Arm64 for OpenJDK, JogAmp on GNU/Linux, iOS, ..

Finally pushed our crosstool-ng-projects configuration to our SCM repositories and published the binaries here.

Changes to the last April toolchain builds are multiple:

  • Updating crosstool-ng to latest release 1.24.0
  • Aligning configuration with Debian 10 (Buster):
    • glibc 2.28
    • binutils 2.31.1
    • gcc 8.3.0 (unchanged)
  • Using 4-tuple symbolic links to 3-tuple, dropping vendor. This allows drop-in usage for OpenJDK cross-compilation via –with-toolchain-path=/usr/local/x-tools/aarch64-unknown-linux-gnu/bin

Debian 10 (Buster) ZFS Live Image Recipe

First of all KUDOS to Debian’s new release this month, Debian 10 (Buster).

Notable to me is the effort for reproducible binaries, which aligns with my security Source Certification Contract (SCC) goals of Are You Who You Say You Are? Trust the Source, User.
Debian’s Buster release PR accordingly:

Thanks to the Reproducible Builds project, over 91% of the source packages included in Debian 10 will build bit-for-bit identical binary packages. This is an important verification feature which protects users against malicious attempts to tamper with compilers and build networks. Future Debian releases will include tools and metadata so that end-users can validate the provenance of packages within the archive.

JogAmp iOS Arm64 Port: NEWT

JogAmp port to iOS, tested on ipad pro 11, arm64.
We use our own OpenJDK 9 x86_64 and arm64 build for the arm64 device and the x86_64 simulation.
The iOS port complements our wide range of supported platforms as demonstrated here. Continue reading “JogAmp iOS Arm64 Port: NEWT”

JogAmp iOS Arm64 Port: First Visuals …

My favorite tagline from Niels Bohr, which I also have chosen for our Jenkins build & test server?

An expert is a man who has made all the mistakes which can be made, in a narrow field.

The OpenJDK build and GlueGen iOS bring-up had its own little challenges, now I walked through another bunch of Apple API wonders as provided by iOS. It surely is not my personal platform of choice by any means, but providing a true platform agnostic solution one cannot choose 😉

So after countless of further iOS obstacles, I finally got a first visual just now: Continue reading “JogAmp iOS Arm64 Port: First Visuals …”

Will making Noise become a Crime?

Functional cryptography, meaning something that works, is feasible for the masses and suits a purpose. Spoiler: They (not only Germany) want to remove that right from you once again.

I remember, back then I used loop-aes for my whole disk encryption. I like this clean module, because it is fully functional. It fulfills the purpose of creating perfect noise over the whole block storage media. No cryptography header or anything else which could raise a flag. Why else would one apply whole disk-encryption if not to at least attempt full deniability? Conventional wisdom dictates that a system is compromised if hardware access has been achieved. Deniable disk encryption is one last resort in these cases. Sadly the Linux kernel community didn’t include this module in its base tree and one would suspect politics were the issue at hand. Instead, we have some soft disk encryption per default, which IMHO is useless as deniability can’t be achieved. Continue reading “Will making Noise become a Crime?”

Oracle Java[tm] 8u202 last supported version for JogAmp

Oracle Binary Code License

Around January 2019, Oracle made its last Java[tm] release, namely 8u202, under their Oracle Binary Code License Agreement for the Java SE Platform Products and JavaFX, last updated 21 September 2017.

This binary license still allows personal and commercial users to use and distribute their binary freely, i.e. commercially use the JDK + JRE, bundle the application w/ the JRE and even distribute the JDK unchanged within an electronic magazine.
