Jussi Ohenoja

Dear friends and Maemoans, as it happens we did not get enough confirmed candidates in the set nomination period, so according to the Council Election Rules we need to extend the nomination period by 4 weeks.

This will push all dates one month to future. The new schedule of the voting is as follows:

  • Nomination period continues until Saturday 29.08.2015
  • Contemplation period starts on Sunday 30.08.2015 and continues until Saturday 05.09.2015.
  • Election period starts on Sunday 06.09.2015 and continues until 12.09.2015.

Currently we have 5 confirmed candidates. (endsormeans, juiceme, reinob, Win7Mac, peterleinchen)

On behalf of the outgoing community council,

Jussi Ohenoja

Gebruik maken van verbanden tussen metadata

Ik beweerde onlangs ergens dat een systeem dat verbanden (waar, wanneer, met wie, waarom) in plaats van louter metadata (titel, datum, auteur, enz.) over content verzamelt een oplossing zou kunnen bieden voor het probleem dat gebruikers van digitale media meer en meer zullen hebben; namelijk dat ze teveel materiaal gaan verzameld hebben om er ooit nog eens iets snel genoeg in terug te vinden.

New syscalls for armv8-64 kernel

I decided to use a different target platform for my project. Initially, I was using Android Kitkat + Galaxy Nexus (ARMv7 + TI OMAP 4460). To obtain best performance with some crypto operations, I am now using Android Lollipop + Nexus 9 (ARMv8 64bits). I did some tests with basic OpenSSL examples (for example, AES-128 and SHA1) and the numbers are impressive.

In my current project, the system has to notify the user about a certain action that actually takes place inside the kernel (in this case, transfer of security keys). I don't want to get into too much details about the tasks, but let's consider that the kernel and the Dalvik are the only trustworthy components and the security keys are stored inside the kernel. I've also seen some pieces of code that helps to implement this, but I could not find a end-to-end solution.

Let's now show how to install a module into the just compiled Android kernel (see this post for more information)

For compiling the module, it's important that you use the same kernel source that is installed in your device. Otherwise, you cannot install the module.

a. Go to the code that contains an example of kernel module for Android (for instance, [your_code]/module/intercept);
b. Update the makefile to point to your kernel source code;
c. You need to set some env variables, including the cross-compiler. In this case, you can use the ones provided by the Android source, in the folder prebuilts:

   @desktop:$ export CROSS_COMPILE=[android_sdk]/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7/bin/arm-eabi-
   @desktop:$ export ARCH=arm
   @desktop:$ export PATH=$PATH:/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7/bin/
   @desktop:$ make
   (a kernel module file will be generated ([your_module].ko) and this is the one that we need to install in our rooted device)

d. Copy the .ko file to the device using the following command:

   @desktop:$ adb push [your_module].ko /data/local/tmp

e. Install the kernel module using the following commands:

   @desktop:$ adb shell
   @android:$ su
   @android:$ cd /data/local/tmp
   @android:$ insmod [your_module].ko

f. You might get some errors, such as "function not implemented". To check more details about what's wrong, you can check the log file by typing the following command.

   @android:$ dmesg

As you need to implement your solution into Android system, you end up learning a lot about the different Android layers (kernel, OS and applications) and how to integrate them. I decided to add the following list with some tips, as these small things took me some precious time to get it solved. The list will be often edited:

#01 - Make sure that you're flashing the device with the proper kernel image

This is what happened to me: I had previously built the kernel (something like two months before). Then, I had to build the OS image from scratch, that is, cleaning up the previous build (with make clobber). When I used the command make bootimage, including setting the variables properly, the output always had the wrong kernel image (not the one that I had previously built, but the existing one in the directory prebuilts). The build process won't take too old kernel images. Therefore, make sure that the compressed kernel image is always new. Even if you don't make any change on the kernel source, do make again to generate a new file.

Updating Crucial MX100 Firmware with Ubuntu

There has been a Firmware update for the Crucial MX100 to MU02. In case you are running Ubuntu there is an easy way to perform the update without using a CD or USB Stick.

As the firmware comes in form of an iso image containing Tiny Core Linux, we can instruct grub2 to directly boot from it. Here is how:

  1. append the following to /etc/grub.d/40_custom:
    menuentry "MX100 FW Update" {
     set isofile="/home/<USERNAME>/Downloads/MX100_MU02_BOOTABLE_ALL_CAP.iso"
     # assuming your home is on /dev/sda3 ATTENTION: change this so it matches your setup
     loopback loop (hd0,msdos3)$isofile
     linux (loop)/boot/vmlinuz libata.allow_tpm=1 quiet base loglevel=3 waitusb=10 superuser rssd-fw-update rssd-fwdir=/opt/firmware rssd-model=MX100
     initrd (loop)/boot/core.gz
    }

    read this for details of the file format.

  2. run sudo update-grub
  3. reboot and select “MX100 FW Update”
  4. Now you can delete the menuentry created in step1

Note that this actually much “cleaner” than using windows where you have to download 150MB of the Crucial Store Executive Software which actually is a local webserver written in Java (urgh!). But all it can do is display some SMART monitoring information and automatically perform the above steps on windows.

Needed to make a Company Presentation recently so thought I would add it here.

EDIT: Two things: IANAL. I'm not stating there is a violation here. You can look at what's linked to yourself - it worries me that the scripts I know to be central to building a mediatek kernel comes with strange headers as well. Not all that's grep'able here is used in kernel. Second, this is my own personal opinion and blog, not that of my employer.

If you want to get your Xbox One/ Xbox 360 running on ubuntu you basically have the choice between the in-kernel xpad driver and the userspace xboxdrv driver.

Most of the guides recommend using xboxdrv as xpad has been stagnating. However using xboxdrv has some disadvantages; as it runs as a daemon in userspace you have to manually take care of starting/ stopping it and giving your user access to the virtual devices it creates.
Xpad on the other hand just works as any other linux driver directly inside the kernel which is more  efficient and hassle free.

Fortunately while pushing SteamOS Valve has updated the xpad driver bringing it on par with xboxdrv:

  • they added support for Xbox One Controller
  • they fixed the communication protocol – no more blinking controller light

Update July 22, 2015

Unfortunately there are still several issues with the SteamOS driver. This follow-up post discusses them and the solutions in detail.

The bottom line is that I updated the official linux driver with chunks found in the SteamOS driver, as well as in several patches floating around the internet. Code and install instructions are available at Github.
