New b43 firmware via ASUS/broadcom? postinst and documentation updates? downstream bugs?

New b43 firmware via ASUS/broadcom? postinst and documentation updates? downstream bugs?

[Drew Scott Daniels]

Hi,
Thanks for all your work on the b43 drivers and tools.

I have some questions that I'm hoping you can help answer, or help point
me in the right direction:

1) Is there new firmware via ASUS?

https://www.asus.com/us/Networking/RTAC66U/HelpDesk_Download/ says:
Version 3.0.0.4.378.9313
Description 	GPL of ASUS RT-AC66U for firmware 3.0.0.4.378.9313
File Size 	567.48 MBytes update 2015/11/16
Download from 	Global

"Global" is a link to
http://dlcdnet.asus.com/pub/ASUS/wireless/RT-AC66U/GPL_RT_AC66U_30043789313.zip
contains
GPL_RT-AC66U_3.0.0.4.378.9313-g53ab20f.tgz
contains other files and the following files (md5sum in front):
ad1372a88f5ce40a1d1e6869d5c24580  asuswrt/License
27030a199072d086d746a679f4f23567

asuswrt/release/src-rt-6.x/wl/sysdeps/RT-AC66U/linux/wl_sta.o

2) Are these ASUS released files GPL that could be included in the Linux
kernel?

3) https://www.broadcom.com/support/802.11 also has a download to
hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz with files dated
2015-09-18 including lib/wlc_hybrid.o_shipped with md5sum
6889dbd24abf8006de5cc6eddd138518. This looks newer than
broadcom-wl-6.30.163.46.tar.bz2 which had support added in 2013 to
fwcutter.

It's hard to tell without trying to cut the files out, and I'm not sure if
that's the right file.

4) http://linuxwireless.org/en/users/Drivers/b43/ lists b43-fwcutter-018
but I see http://bues.ch/b43/fwcutter/ lists:
b43-fwcutter-019.tar.bz2	25-Jun-2014 16:05 	46K

5) http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/ lists
http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 but
http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/developers/
shows a table with a link to
http://www.lwfinger.com/b43-firmware/broadcom-wl-6.30.163.46.tar.bz2 which
looks newer. Does it not work as well as 5.100.138?

6) b43-fwcutter-0.19.tar.bz2 contains:
./debian/firmware-b43-installer/DEBIAN/postinst
that downloads broadcom-wl-5.100.138.tar.bz2 and not 6.30.136.46
Debian and Ubuntu b43-fwcutter_019-2 contain the same postinst.

7) Debian, Ubuntu and Arch are all tracking issues with b43-fwcutter
including file permissions being 750 or 755. See:
https://launchpad.net/ubuntu/+source/b43-fwcutter/+bugs
https://bugs.debian.org/cgi-bin/pkgreport.cgi?repeatmerged=yes&src=b43-fwcutter
https://aur.archlinux.org/packages/b43-firmware/
Fedora doesn't list any open bugs at
https://apps.fedoraproject.org/packages/b43-fwcutter/ and doesn't seem to
have the postinst script.
There may be other issues being tracked in the other distributions like
openSUSE.

Are the file permissions intentional? Just needed temporarily?


Thanks,

It is new firmware for that ASUS AP, but it is impossible to tell whether the 
b43 firmware is new.

The short answer is no. These .o files do have the b43 firmware included in 
them, but it would be useful only after extraction using b43-cutter. The 
resulting firmware files would not be redistributable. Including a file of 567 
MB in the kernel or in any distro will not happen. That is why the distros 
include a script to download some file and run fwcutter on it.

It appears the wiki needs an update.

The wiki at en/users/Drivers/b43/ is out of date. I have no idea what the 
changes are between firmware version 666.2 and 784.2.

I do not know who wrote that code and as I do not understand Debian installers, 
I will leave that question for them.

The extracted firmware files are created with permissions 311, which is correct. 
If they end up with some other permissions in some distro, I expect that is a 
problem with their installation process. On my openSUSE 13.2 system, the 
permissions are correct.

The firmware version is 784.2. It is not new b43 firmware.
