Need support for DD-WRT v24 preSP2 #78

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. ./extract-ng.sh
2. nothing
3. ./build_firmware.sh

What is the expected output? What do you see instead?
The image is builded ok, but it fails to flash through the web-interface on the 
same version of DD-WRT.

What version of the product are you using? On what operating system?
DD-WRT r19519-r20119, FMK r360.
Please provide any additional information below.

I assume DD-WRT changed their webui package and/or firmware image yet again as 
to break compatibility with the FMK, quite intentionally. From a legal 
stand-point, I believe support can only be added if he continued to use 
modification of GPL'd F/OSS tools (afaik) to create his webui. If he didn't, 
then we get into grey territory. From a consumer stand-point, you should at the 
very least be mindful of this not being a F/OSS project anymore, at least not 
in the true or full sense of the word, in my opinion.

'this' being DD-WRT of course

However, the source code available under the GPL?

GoogleCodeExporter commented 9 years ago 
DD-WRT's source code GPL.. well, being a derivative work you would think, and 
it always has been from top to bottom to the best of my knowledge. But, is it? 
Can you download and compile it? To date, I've not known anyone able to. 
Supposedly it is possible, but many developers have given up after addressing 
countless build problems and potentially huge missing components (e.g. the 
precious web ui, I am not sure if its presence is there, and if it is there 
somewhere, it is likely in its post-compiled/encrypted form). Ironically, as I 
allude to above, the tool he has used in the past to encrypt/decrypt his web UI 
is again a GPL derivative work, afaik. Thus, his modifications to it should be 
required to be published, but I'm not sure on this, and am no lawyer. He may 
well publish such if asked. In general, you get the idea, this F/OSS project 
has gone commercial and, seemingly at least to me, taken a lot of steps to 
protect itself from clones, forks, etc.. that normally come with a F/OSS 
project. That is fine and dandy if the code is 100% your own, but when you get 
into derivative works, that violates some licenses, in some cases, though I am 
not making any accusation or claim here. That's about as carefully as I can 
word things while being polite, thorough, and defensive.

And I think the evidence is the now several changes made specifically to break 
compatibility with this simple Firmware Mod Kit... Nothing new though, that has 
happened for years.

Though this is all assuming the issue is not just your own ... which I assume 
it isn't. You can test this by simply using an older revision of DD-WRT v24 SP2 
(same version number that has existed for years).

Difficult English for me. :)
But the essence I understood, and I agree with you. How easy is it to compile 
OpenWRT, and how many problems with DD-WRT...
I was just hoping that changes in the method of compressing images/GUI 
insignificant, and they will appear in your project.
Suffer with the Assembly of 12GB of source code, to change, sometimes, a couple 
of lines...

I tested on different images from here:
ftp://www.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2012/
(requires version starting with r19327 to support the RT-N13UB1 (for Zyxel 
Keenetic).

What are the results of the tests? Did older images work? If not, then despite 
my rant, it may be an issue of compatibility with that target device.

Hmmm... Sorry, I guess my statement of support for SP2 sounds wrong, the 
problem is with the way Asus-RTN13UB1.
With D-Link DIR-615(D) revision 19519 
(ftp://www.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2012/07-20-12-r19519/dli
nk-dir615d/)  disassembled and assembled successfully. But not work with Asus 
RT-N13UB1 image (testing with Zyxel Keenetic, some hardware, do not have the 
possibility to check the original RTN13UB1) - 'write /tmp/??? linux' exit with 
error, 'Upgrade failed.' in WebUI.
asustrx code? The resulting size is correct, the modified firmware successfully 
unpacked again.

Did you happen to solve this issue?

I have a similar issue.  I used the latest firmware-mod-kit on RT-N13UB1 fw 
images as follows:
1. ./extract-ng.sh
nothing
2. ./build-ng.sh

When I attempt to flush the new image into the dd-wrt device using web 
interface I get the "Upgrade failed." error message with no additional details.
I have also tried flushing the image using the tftp, and the device seem just 
to hung.

Any ideas where I can find more information on how to fix this?

I have also attempted to deconstruct and build DD-WRT v 20453 for the Asus 
RT-N13U (not B1), formware can be found here: 
ftp://www.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/01-01-2013-r20453/As
us-RTN13U/

extract-ng appears to work for the .bin, but even with no modifications it 
builds to a size greater than the original.  If I use the -min flag I can get 
it to build but then the firmware is incorrect, and bricks my device (brought 
back to life via asus restore utility ofc).

extract_firmware on the trx does not work, as it cannot identify the 
filesystem.  I get a segfault which I traced back to unsquashfs.

I'm a little perturbed to hear that brainslayer might be intentionally mucking 
with things to break compatibility with fmk.  Can't see the logic behind that.

In any case, if there is a possible resolution to modifying these latest DD-WRT 
firmwares please let us know.  The latest build is the first that will fit on 
this router in over a year.

Did a test of extracting/building/extracting and got some interesting results.  
Notably, the first extraction grabbed a 16-byte footer while the second found a 
32-byte footer.

Attempted to use extract_firmware/build_firmware on the trx of the firmware for 
a different version of my router (B1, available here:

extract_firmware.sh did *appear* to work on the B1 firmware, but when 
rebuilding I noticed this warning:

Support may vary depending on the target device, but generally speaking, all 
should work. The FMK has improved the last month. Retry, if problems, submit a 
new issue with a specific link to the firmware you are playing with.
