Mounting windows shares on kindle PW2 (542)

[san3]

Hi,

at last I managed to mount my samba shares on kindle paperwhite 2 with cifs and wanted to share the howto in case anyone else is interested.
I'm not really used to compiling stuff for linux yet, so there might be easier ways, but it works.


First I compiled the cifs kernel module from recent Kernel sources
With codesourcerys arm toolchain. For details on compiling the kernel check yifalu's page or Christan Hoffs


In short

make make ARCH=arm CROSS_COMPILE=PATH TO YOUR TOOLCHAIN/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- imx60_wario_defconfig
make make ARCH=arm CROSS_COMPILE=PATH TO YOUR TOOLCHAIN/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- menuconfig
here you choose the modules 
make ARCH=arm CROSS_COMPILE=PATH TO YOUR TOOLCHAIN/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- modules

It took me a while to find out all the modules required for cifs to work.
First of all: the cifs.ko
Additionally different crypto modules:
md5.ko
md4.ko
des_generic.ko
hmac.ko

After compiling I loaded the into the kernel

insmod /PATH to/module.ko

and mounted my samba share with cifs

mount -t cifs //server/share /PATH TO FOLDER -o user=X,password=Y

I included the kernel modules, but i expect they only work for kernel version 5.4.2

Very nicely done! I don't have a PW2, but the process should be the same. Thanks!

Ah - they only work for the version of the Kernel that shipped with **FIRMWARE** version 5.4.2
(Use: uname -a command to display that information.)

Which, in general, never changes during the lifetime of the product regardless of other firmware updates.

[san3]

ah yes of course ... Kernel Version is 3.0.35
hmm ... now that I think of it:
It doesn't look as if they switched the kernel between 5.40 and 5.42 right ?
I recently compiled a tun.ko module from the sources included in the 5.40 code release that didn't work on v. 5.42 kindle. I had to recompile using
the sources from 5.42 ...

Good old symbols table issue?

[san3]

Possible ... but I'm not sure I get the "good old symbols table issue" yet - have to find some time to read about it.

Anyway: I made a small kual extension including the modules and a bit of code to load everything. Just edit the mount.sh and unmount.sh according to your needs.

Btw: I have had no issues with this, but it should be considered as experimental.

Thanks for the files - it seems zip or gz files are preferred here. If it works well, consider adding it to the KUAL extensions sticky thread. You can specify PW2 only if you want.

ok. np

Please post your experiences if you try this.

I have a kindle touch running 5.3.7 firmware with an older kernel:
Linux kindle 2.6.31-rt11-lab126 #1 Fri Jul 12 02:22:50 PDT 2013 armv7l GNU/Linux

I tried to make the same modules as you did, but some didn't like to me modules in my make menuconfig? I did make cifs, hmac, and md4 if they are needed (attached). I don't have a windows machine nearby to test, but I can mount a samba share in linux. Not quite the same

Oh - I used imx50_yoshime_defconfig instead of:
imx50_yoshi_defconfig
imx50_yoshime_defconfig
imx50_yoshime3_defconfig

I wasn't sure which to start with, so I guessed.

I built the kernel modules in my qemu chroot partition and then copied them over. Seems to work for me, but I would love to hear anyone else testing this also!

Getting insmod error -1 "Invalid module format" from inserting the .ko files on kernel 3.0.35-lab126. It's a PW3.

Modules are not universal, the must be built to match the kernel that will be using them.

See post immediately above your own, do you see any builds for recent kernels on i.MX6 devices?

That is your starting point, build what you need.

I know this is an old post but would this work on the latest Kindle?

[NiLuJe]

You'll have to build the cifs modules for the right kernel for your device/FW combo, but, apart from that, most likely.
