Re: Possible GPL violation in Canyon CN-WF514 WLAN router

Hi!

(lkml readers please consider replying to me or tech and not to lkml)

I posted [1] on the GPL-violations mailing list, but got no response, so I'll
try here.

What :

  It seems Canyon [2] distributes [3] a firmware update file [4]
  for their CN-WF514 WLAN router that contains the linux kernel
  image. nmap scan guesses the router is running "Linux 2.4.X|2.5.X"
  There is no mention of used GPL software and no source code.
  A direct enquiry to Canyon was responded with : 

This product is not using GNU GPL license.

(yes, that's all of it)


What I need : 

 Help disecting the FW package [4]. It is a ZIP archive containing 
 a text file and a *.bin file. This *.bin file appears to be some kind
 of another archive, containing two files : webpages-6104ipc.bin
 and vmlinux.bin
 The *.bin archive file begins with the string "WBIP". I guess it uses
 compression, since "strings" does not give out anything useful, except
 the mentioned two filenames.
 There[3] is another firmware update [5] that is in slightly different
 format. "strings" there finds this :

RtosTxImage
Uncompressing Linux...
Ok, booting the kernel.


Any ideas ?

As this is partly off topic for lkml, I suggest replying to the gpl
violations mail list.

Here is what I asked Canyon and got the above answer :

Is any software distributed with the CN-WF514 router,
that is licensed under the GNU General Public License ?

Hm, maybe they thought I'm talking about the acompanying
CD media ...

David Balazic
