Unfortunatly it seems that broadcom is in no way interested in releasing the specifications. I actually had a chat with the guy who's in charge of driver develpment for that chipset over there and he said that there was "sensative data" which the Government had banned them from sharring. It would seem that there are capabilities built into the hardware which are limitied by their drivers. This is unfortunate however he did express intrest in producing closed source linux drivers and is still currently in the process of hiring linux developers....so it's probably not too far off in the future. I'd exspect the source forge project to be completed before broadcom actually releases one however. Sorry about the bad news.

As an update from the sourceforge project: We've now decompiled 64% of the driver and are continuing to decompile and write up information regarding the registers used, memory addresses etc. We've got a new site that should go up in a few days that should keep everyone more informed of the progress.

What could the community do/provide to speed this along? Anything?

What's preventing it from being done? Time? Manpower? Finances? Hardware?

yes yes please let us know if there is anything you need.
I would be happy to test any version on my new ibook G4.

I do have a question... any idea what these hidden airforce features are? I am assuming it has something to do with encryption, as I believe encryption that is too strong is illegal in the US. This is probably nothing I would find useful, I am just curious what this super secret sensative feature is.

again, contact me if I can help.

From what I've understood from JoseJX they follow this procedure:
1. Decompile the binary driver to c code. This code will not be made public since it is basically broadcoms source code.
2. Look at the decompiled source and write down specifications of how the chip works. Those specification documents will be made public.
3. Write new drivers based purely on the written specifications. This will be completely new code with absolutely no code reused from the decompiled source. This to avoid violatiing the IP of broadcoms driver.

So until the specifications are written up and published there's not much that can be done to speed things up.

that's sound very interedting
what are theses hidden capabilities???
is it interesent for a user/hacker or it's only ininteressant military stuff as protection to interferences or things like thiis
maby it's a combinaison between:
-changing frequency atvery high rate
-very high end efficient cripting alghoritm

that would be cool...i could have wifi without preocupating me about security and it wouldn't be anymore the huge security hole that evrybody is talking about

powerbook/panasonic notebook +hummer + airport extreme lol that would be fun

Thanks for that... Decompiling is no fun =(

I've got a HP notebook with this chipset, and even though it's not PPC, the topic here got my attention... I contacted Broadcom's web support, asking them to say something official about linux support for the 4306 chipset. This is what I got:
Quote:
Case Title: Linux support please!!!

Response from Broadcom: Support for Non-Ethernet NIC Products Broadcom offers support for its BCM57xx and BCM4401 Ethernet controller products only.
Since we do not sell products directly to end-users, we do not offer comprehensive support for Broadcom's customers' products.
If you are having a problem with a Broadcom-based Ethernet controller product, please contact either the PC or board manufacturer
for technical support.


Don't know what that has to do with what has been said here, about Broadcom hiring linux developers to work on binary drivers, but it certainly didn't motivate me.... I'm using ndiswrapper right now, and I can't connect to b networks, so I really want a proper native driver :(
