Kindle Touch/PW1/PW2 5.0.x - 5.4.4.2 JailBreak. Plus FW 5.x USBNetwork. - Page 27

Yeah, my main issue is that it's a bitch to do in a safe/sane way on FW 4.x & 5.x, because the modprobe call is (and has to be, to avoid a host of weird shit) handled by volumd, and can only be tweaked through kdb, whose db lives in a ro cramfs... So I'm open to ideas on how to handle that safely, in a not too ugly way...

Aside from that, knc1 mentioned building the mac address based on the s/n, which is a pretty neat idea.

OK, mac address ball is in my court now.
Let's see if I fumble it.

OUI field - Can't find one registered to Amazon under any name that I can think of, so . . .

Will steal an OUI from the reserved field CF:00:00 ... CF:FF:FF (some PPP registrations - as long as we don't collide with Amazon's 3G MACS - will make my choice carefully to avoid the registered 3G carriers).

(CF:DE:AD jumps to mind)

Edit:
Looks like that is workable:

The unique USB networking MAC addresses plan.
Both ends of the cable **should** have a globally unique MAC address.

Code:

[root@kindle root]# cat /proc/usid ; echo
B0241604311703FA

Make a conservative estimate of the entropy in that:

Code:

B024  - 5 bits
1604311703 - 10 * 3 == 30 bits
FA - 2 * 4 == 8 bits

Total entropy: 43 bits, need at least 48 bits

Code:

[root@kindle root]# cat /proc/board_id ; echo
00A1607131130CYG

That is certainly another 3 bits worth.

Code:

[root@kindle root]# cat /proc/usid /proc/board_id ; echo
B0241604311703FA00A1607131130CYG

That should serve as the "Hello, I am: ...." name tag.

Now, not to disclose device private information, take a one-way hash sum:

Code:

[root@kindle root]# cat /proc/usid /proc/board_id | md5sum
af75bab85599c7cc2abb95a248da709b  -

With a bit of string chopping:
af:75:ba
b85599c7cc2abb95a248
da:70:9b

Plus the prior post OUI, yields (on the Kindle):

Code:

g_ether dev_addr="cf:de:ad:af:75:ba" host_addr="cf:de:ad:da:70:9b"

And on the workstation end, stuff a rule file into the /etc/udev tree, like:

Code:

ACTION!="add", GOTO="net-end"
SUBSYSTEM!="net", GOTO="net-end"

# Kindle USB network interface name(s)

# My first paperwhite's persistent USBnetwork interface name:
ATTR{address}=="cf:de:ad:da:70:9b", KERNEL="usb*", NAME="kpw0"

# Others

LABEL="net_end"

Now, whatever network automation your workstation uses, it can configure for a specific Kindle by the interface name (kpw0) you assigned in your rules file.

Next -
Figure out how to automate that in the Kindle's firmware image.

Okay, got something working on the unique MAC addresses front. For the K2/3/4 for now, will port it to FW 5.x in a bit. Hopefully will be less painful.

As I feared, the volumd handling is terribly awful, so it's hidden behind a config switch, but it appears to work, and handles both sides.

EDIT: K5 port done.

(Everything's on SVN, if someone wants to take the plunge).

Dumb question: What SVN?
Maybe a link to it?

NiLuJe · 08-09-2013, 09:41 PM

Legacy: https://svn.ak-team.com/svn/Configs/trunk/Kindle/Hacks/

Needs to be checked out side by side or the buildscripts will shout at you

I haven't (yet) done an integration package for the KUAL Firewall and the KUAL USBnetworking applications.

i haven't intstalled any firewall or filter, although i am planning to do it soon.

Haven't tried it yet, but have had time to do a bit of "proof reading".
Looks like you have the unique MAC address problem solved for the next release.
A big: Thanks for that.

In the mean time, I will just plug in my kindles one at a time.
**AND**
Work on fixing the various problems of my own posted buttons.

NiLuJe · 08-10-2013, 11:37 AM

@knc1: Great, thanks for taking a look at it

.

That said, if someone has a better method to trick volumd, I'm all ears, because the current workaround isn't terribly pretty...

.

NiLuJe · 08-17-2013, 12:19 PM

Released USBNet 0.10.N, which includes, besides updated binaries, the unique MAC address stuff discussed before.

As mentioned previously and in the comments of the config file, I wouldn't recommending enabling this unless you really need it, the way it's implemented isn't really pretty

.

It's hidden behind a config switch, so you will need to update your config file manually if you have customized it. There's now a KUAL button that restores the default config, and the default config is available in usbnet/etc to ease manual merging.

Thanks a lot -
Since it is a "development environment" sort of thing, a developer should be able to deal with a hidden option.
And/Or with reading the directions.

NiLuJe · 08-17-2013, 06:04 PM

@knc1: True, but the behavior isn't specific to this switch, it's just how the installer behaves to try to preserve non-default config files. This was just the perfect example to explain this again, and introduce some stuff to help managing custom configs (hence the KUAL button)

Great work..

How do i upgrade from v0.9.N..?

uninstall, re-install..?
