Post your request for December Release

Currently the Barrier Breaker build is proceeding smoothly.
I integrated a few performance enhancement patches from QCA Upstream SDK.
Switched the Kernel Modules to AutoProbe loading and enable faster math routine for hostapd.
Changed the Kernel Clock to 250HZ instead of 100HZ.
All the changes are shown on my Github.

So the question is what additional programs do you guys want precompiled with the same optimization build?
I will not be building the modules into the kernel images as I want to leave free space for people to customize their own configuration.

For you guys who want certain programs I will add them as module and which you can manually download from my github repository.

Leave a post below if you want anything.

Barrier Breaker Release

OpenWRT Barrier Breaker has been released.
I have also uploaded the binaries on github under October Builds.
The new binaries are created by using my new patch builds
Previously I mentioned of using a new way to maintain my own patches and optimizations.
The repositories are here:

For Barrier Breaker WDR36XX/43XX
For Barrier Breaker WR1043ND

With this patches you can create your own builds easily.
Changes are clearly documented in the patch folder with each change written in the patch.
  1. mips16 is fully disabled as from my testing it doesn't seem to help in code compression and introduce execution overhead
  2. Add 24kc/74kc mtune flags to the respective router architecture
  3. Skip Certificate Checks on wget
  4. Renaming of LuCI pages
  5. Fix and unbrick LuCI OpenVPN packages and pages
  6. Add additional LuCI Switch features
  7. Add more LuCI Wifi Configs
  8. Sysctl default optimizations
  9. Remove PPPoA completely as it is only applicable for xDSL Devices
  10. Modify UPnP broadcast model names
  11. Unbrick L7-protocols
  12. Add some optimization I found in Lantiq SDKs
  13. OverClock Ralink RT3052 SoC to 433MHZ tested stable
  14. Change muti-wan pages 
  15. Unlock Wireless Regulatory
  16. Change Linux kernel config
  17. Use latest Kernel, Binutils and GCC
  18. Reduce ZRAM size
  19. Remove whatever unnecessary debug
  20. Fix bootstrap theme for mobile devices
  21. Disable firewall mss by default to increase NAT performance
  22. Disable unnecessary start ups by default
  23. Add additional function for realtek switch RTL8366RB
  24. Minify and Compress CSS and Javascript using yuicompressor and closure .
Upstream changes that breaks the patches are displayed during build process
Patches automate the compilation with the new patches I can build OpenWRT firmware for a particular Router under an hour assuming the sources have already been downloaded.
Porting to different branches like trunk is a breeze.
Consistency in the builds is assured.
Read the README in the repository for more information.

I made a lot of changes in the new builds
A lot of packages deemed unnecessary and big are removed.
If you want them you can download them as ipkgs and install it to the router.
Reason is most people do not solder 16MB flash on their router.
Giving them the flexibility to specialize their purpose is better.

If you are upgrading from older release it might be a good idea to try to reconfigure from scratch if your own config does not work. Then port the settings over.

As for benchmark of Barrier Breaker using my binaries on my Overclock@430MHZ WR1043ND.

TCP on JPerf NAT LAN TO WAN:


UDP on JPerf LAN TO WAN:


Wireless Performance Close Range No Encryption 2.4GHZ Band 40MHZ Force HT ( Fat Channel)


Wireless Performance Close Range WPA2-PSK 2.4GHZ Band 40MHZ Force HT (Fat Channel)


Some packages in my Repository might not be present in the official Barrier Breaker repo like LuCI OpenVPN which I unbroke in my Patches.
In that case download the individual ipkgs upload to your Router and install them.

Multi-Platform Portable TrueCrypt

This post about my latest creation, a portable multi-platform TrueCrypt that you can install on any generic cheap flashdrive.

Flashdrives controllers are actually programmable devices and manufacturer tools can enable special modes that can enumerate other devices like CD-ROMs.

This is very useful when we want to enable the same filesystem to deliver multi-platform binaries.
For people who value privacy and protection but do not have the money or means to buy secure encrypted flashdrives this article is very useful.

A show case of what it can do:

On Linux

It is enumerated as a Virtual CD-ROM Drive:



Double Click on TrueCrypt.sh

 


It launches TrueCrypt. Works for 32bit and 64bit Linux

On Windows

It appears as a CD-ROM Drive

 
 
Double Click on it to launch TrueCrypt.
And TrueCrypt launches...Works for 32bit and 64bit Windows

On Mac

Just Double Click on TrueCrypt.app

I don't have a screenshot because I don't care to own a Mac but I included it anyway for it to be truly multi-platform.

How to Obtain the Virtual CD-ROM Partition

Different FlashDrives use different controllers.

To obtain information about your FlashDrive use ChipEasy or ChipGenius.

 

As you can see my FlashDrive uses a Phison Controller.
The tool to enable addition modes in Phison Controller is called ModeConverterFF01.
For more information about different controllers and their manufacturers please visit
www.usbdev.ru

Google Translate is your good friend.
I will not be including the manufacturer tools because they are not OpenSource Freeware.
Be careful when downloading files from China Sites, malware advertisements abound!

 

How to use ModeConverterFF01

 

As you can see it is very simple, select 2 partitions and and choose the TrueCrypt.iso image and click Convert.
Make sure the size allocated is more than 26MB which is the size of the ISO Image.


Where to get the ISO File

Download it here from my github.

Why TrueCrypt rocks?

Regardless of the real reason why it was discontinue it is still useful because
It has been code audited but make sure the version is 7.1a.
This ISO I created is based on TrueCrypt 7.1a.
http://istruecryptauditedyet.com/
It can create encrypted File Containers and Volumes and Fake Volumes to confuse people who wants to look at your files.
It is portable as shown in this entry.

How to use TrueCrypt?

Please Google, there are 101 articles online to teach you.
There is also a guide included in the ISO FS.
