Libnice 0.1.0 released!

Posted on by

Yesterday, I released a new version of Libnice, This is a new major version that has a small API/ABI break from previous versions.

Here are the main changes :

  • Added nice_candidate_copy to the public API
  • Make stun_timer timeouts configurable (Breaks API and ABI)
  • Add compatibility support for MSOC 2007 and MSOC 2007 R2
  • Add MS-TURN support for MSOC
  • Added and completed TURN RFC 5766 support
  • Add a nice_agent_set_port_range API to force a component to use a specific port range
  • Fix various bugs and memory leaks
  • Improved documentation

The API and ABI break is with the StunTimer usage, so if you use it, you’ll need to do a small change to your code. Because the library version changed, you’ll also need to recompile your applications that link with libnice.

The biggest change in this version is the full support for the recently published RFC 5766 TURN standard (UDP and TCP) as well as the addition of MS Office Communicator compatibility. The API/ABI break introduced in the StunTimer usage is to allow specifying the timeout of STUN retransmissions. The timeout for the STUN and TURN discovery during the candidate gathering phase has also been lowered to 3 seconds now instead of the 9 second timeout that we had before, which should make for a quicker candidate gathering phase and a more responsive UI.

Another interesting change is the addition of the nice_agent_set_port_range API that allows you to specify a range of ports that you want a component to listen to for host candidates. This should help those who use port forwarding with symmetric NATs.

The stun_usage_timer configurable timeout as well as the nice_agent_set_port_range addition were suggested by Tom Kaminski.
The MSOC support was added by Jakub Adam.
The RFC 5766 TURN support was added by Marcus Lundblad and myself.
Other small fixes that were reported on the libnice mailing list were also fixed and included in this version.
Thanks to everyone who contributed in this release and thanks to Collabora and Nokia for sponsoring that work!

A new version of Farsight2 has also been released today (0.0.23) which should work with the new API of this Libnice release.

You can download this new version of Libnice from the usual place.

Enjoy!

Youness.

PS3: First ‘Custom Firmware’ now working!

Posted on by

Update: I’ve now fixed the issue about the missing game data icons. PS3-Hacks.com has a nice step-by-step tutorials and they posted the PUP files.

Update 2: DO NOT try to install this from the service mode, it might brick your console, install it normally from the normal menu or the recovery menu.

Great news!

Thanks to the tools made by the fail0verflow team (and thanks to sven in particular for his work on the pkg/unpkg tools), the first “Custom Firmware” is now available for the PS3!

I see a lot of questions coming up really fast on my Twitter account, so here are the basic things you need to know :

Because of legal/copyright issues, I will not provide the custom firmware to anyone, however, I’ve made available all the tools necessary to transform an Official firmware update, into a custom one, just grab my ps3utils repository from github, compile, then run :

./create_cfw.sh PS3UPDATE.PUP CFW.PUP

This will take the official firmware, unpack it, modify it, then repack it correctly (requires you to install ps3tools).

This should work on Linux and Mac for now, but I’m sure others will do it for the masses and illegally release those files somewhere.

The advantage here is that you can do it for any firmware, if you want to keep version 3.41, then give it the 3.41 update, if you are on 3.55 already and can’t downgrade, then run the script on the official 3.55 firmware and it will create a modified 3.55 firmware.

You can put the file in a USB drive under the filename “PS3/UPDATE/PS3UPDAT.PUP” and then go to system update in the XMB, and it will allow you to install the update (even if you’re already on 3.55).

People are asking what are the features of this firmware, it’s simple, all it does is to add those “Install Package Files” options to the Game section of the XMB. It doesn’t do anything else!

This firmware will not allow you to run the currently available homebrew application. Once the homebrew developers re-package their files in a ‘retail’ .pkg format with signed executable, then it will work (this should be coming soon thanks to the work of the fail0verflow team).

Since the kernel is left unmodified, this means that this custom firmware is really meant for future homebrew installation, and it will not allow piracy. I plan on keeping it that way.

This is just the first attempt at custom firmware, and it only contains a minor modification to allow you to install pkg files directly, eventually we’ll get some more options added to it in the future. This is just starting to get interesting!

p.s: Thanks to everyone who helped make this possible!

Enjoy! 🙂
