Extracting kernel config from I9000XXJP3

Dear all,
Did anyone succeed extracting kernel configuration from I9000XXJP3? Kernel version is 2.6.32.9, the vermagic is "2.6.32.9 mod_unload ARMv7"
extract-ikconfig doesn't work on it.
I succeeded extracting a zImage gzipped payload, but it seems not to contain any configuration in it (see attached).
/proc/config.gz doesn't exist, Samsung open source package (downloaded from Samsung open source site) contains only Android 2.1 Eclair or previous versions.
My target is to build tun.ko and, eventually, ext3/ext4 modules to make them working in Samsung Galaxy S I9000 with rooted I9000XXJP3.
Any idea?

Without froyo source code or a good Samsung Kernel (es. for himem capable) I think is impossible to play good with theses beta roms.
Ciao

Any news? I need tun.ko for jp3 too..

I have tried to compile the 2.6.32.9 kernel editing the .config in 2.6.9, the module tun.ko is accepted by the device, but I get a kernel panic!

Did you use the stock linux kernel? Or the common from android.kernel.org?
I'm trying the same thing actually. Isn't there any default config for the processor that might work? I tried with the config from .29 but when loading the module it says wrong format.

try to build 2.6.32 with the 2.6.29 config ("yes" all missing stuff)
turn on your galaxy, adb push the tun.ko
try to load it, it will say "missing symbols" blabla
find the config options that match those symbols, enable them, recompile, try again

Great to see some people who are hacking the kernel! Keep it up!
But I'm afraid it is not going to be as easy as dropping aries_rev03_defconfig as .config in a 2.6.32 kernel tree and doing 'make oldconfig'. That's because many of Samsung's changes have not been included in the newer mainline kernel versions yet.
Samsung added quite a lot of low-level board support for their dev boards (and for the SGS, of course), did some customization and added a few drivers which you will need to forward-port to the newer kernel.
Please have a look at this thread, in which I've started a breakdown of the Samsung patches against Android Eclair's 2.6.29 kernel.
The best course of action I think is to git clone Android's kernel from AOSP, checkout the android-2.6.29 branch, apply Samsung's patches to that, then attempt to rebase your tree to a newer kernel version. (Note, you may want to start with small steps, to get a feel for what you're up against )
Note that there probably will be lots of merge conflicts which you need to resolve, and after dealing with all those, you also have to make sure that everything else that's merged still works as expected, but at least that will show you the amount of work involved. You will basically be doing all the work that Samsung is doing right now for their kernel for FroYo. It will be interesting to follow their progress on the mailing lists and on IRC.

Thats exactly what I did, but I got wrong module format... which is a fatal error. I need to invest further in the used config... maybe i did not pick up the right one properly..

Yes that would be a lot of work. Maybe its better to just wait until they release the kernel from froyo. I read that they release their opensource stuff rather fast. But just for adding a module like ext4 I don't think you need those patches, because imho they didn't touch the fs of the kernel. We just need an adaquate kernel config and adding modules should be possible.

Make sure you're using the same kernel version number and build number, because samsung kernels do not have the option to load incorrect module versions

Yes i've set the subversion as well but without the patches from samsung its impossible it seems. We need to wait and hope that they release the froyo kernel sources soon....

Are you sure they set CONFIG_MODVERSIONS? It's off in the downloadable sources.
Just compare the output of `modinfo -F vermagic <yourmodule>` to `modinfo -F vermagic <modulewhichloads>` or to /proc/version .

did this get solved yet? I google'd for the tun.ko file for my i9000 using jp3 but nothing yet... if you have a proper one for the MoDaCo version here please attach it! ~

I think I saw someone's post with tun.ko for FroYo beta somewhere in these forums, I mean i9000 Android Dev. One of the guys here has found a way to compile kernel for jp* here. I am sure.

I actually found it attached somewhere in the forum and it was 1,5447 mb big I think it was... but it still didn't work for me so I presumed the kernel or something must have been wrong.

[Request] tun.ko for kernel 2.6.32.15-ge2fb08e

Will someone please make a tun.ko for the new released kernel or send links on how to and the tools needed? Thanks in advanced.

until HTC releases the source for kernel 2.6.32.15-ge2fb08e
we can not compile a "Real" tun.ko
I modified the version string on the current released code 2.6.32.15-g746f4f0 to ge2fb08e and am compiling it right now.
This will allow it to load and as long as there are no major changes in the kernel it could work for you. It will at least load so you can test it.
I will up load it as soon as it is done compiling

to build it yourself
you can get instructions for an android build system here
http://source.android.com/source/download.html
download the source from HTC http://developer.htc.com/
you will need a .config file should be /proc/config.gz on your phone, uncompress and rename to .config
http://code.google.com/p/android/issues/detail?id=3803
you will need to setup your path to include the build environment you download from source.android.com I will put mine at the end of this
edit the Makefile and change EXTRAVERSION = .15-ge2fb08e to contain version string you need
do a make modules
as long as the kernel has not changed to much from the base source HTC has provided it should work.....
I added the folllowing path statements to my .bash_profile

Tun.ko vermagic=2.6.32.15-ge2fb08e
the attached tun.ko is build from the released HTC source with the version string changed to ge2fb08e
as long as the kernel has not changed much on the leaked kernels this should load and work
[[email protected] net]$ strings tun.ko | grep magic
vermagic=2.6.32.15-ge2fb08e preempt mod_unload ARMv7

You are awesome. Thanks
update - The tun.ko does work so it looks like the leaked kernel did not change much.
I will try and learn how to make one. I have ubuntu in vmware to use. Does this have to be a linux box or can it be done on a MacOSX?

Do you have the cifs.ko and nls_utf8.ko for 2.6.32.15-ge2fb08e?
I am trying to get cifs working on my evo.

Never mind. Thanks for everyone's help.
Here is what I did to get the cifs.ko and nls_utf8.ko (from here http://forum.xda-developers.com/showthread.php?t=754793) to work for my kernel.
I took the cifs.ko and nls_utf8.ko created by "snq-" and used a hex editor to edit the kernel number to match mine.
That was all, no re-compile needed. then I followed the rest of the steps laid out by snq- to install the files and test them.
Lastly I installed CifsManager which is available on Market and everything worked.
I am able to connect to my network only locally. Comcast seems to be blocking ports so I cannot access smb from outside my network.

please post link for cifs.ko
If you have a working cifs.ko for this kernel, please post a link!
Thanks!

Any Suggestions
Any where else to go for a tun.ko for ge2fb08e? I've almost exhausted my searching. Thanks!

i am trying to set up OpenVPN on my Evo with the same ge2fb08e kernel version. i installed the pre-requisites, but do not have the tun driver. can you send me a copy of the tun.ko zip? TheEdge88

SR, You can download the tun.ko file in the previous post, but you need to post 9 more times before you can access it. It worked for me and now I can connect to the OpenVPN server. I think I still have a problem with routing though.

[HOWTO] tun.ko to run OpenVPN on Froyo xxJPK Galaxy S I9000

NOTE: there is no guarantee this will work, because without access to the corresponding kernel source I can't be sure. It may wipe out your device if there's memory corruption! You're warned, use it only at your risk!!
Over the last weekend I wanted to familiarize with the arm assembly, buildsystem, SDK so I created a tun.ko module for kernel running in the JPK ROM. But lots of the time was also wasted trying to guess their config (things like disabled DMABOUNCE and removal of the dummy they added in 2.6.29 from struct net_device, I hope I got it all right).
I encourage to release the kernel source along with the ROM images in the future (it'd be much simpler if there was a git tree that they can just tag with the name of the ROM), and to include the tun device into the modules/tun/tun.c (as in the tarball) so that it is included by default in the future. I won't be doing this process again.
I had to install openvpn with the openvpn installer a second time with openvpn in xbin, busybox in xbin/bb and I created the bb directory and two symlinks from xbin/bb/{ifconfig,route} to xbin/busybox (after mounting /system rw). The DNS to change during VPN must be set by long pressing on the left of the openvpn config slot in the OpenVPN settings GUI.
The tun.ko I keep it in /sdcard/openvpn/tun.ko and the path has to be configured in the openvpn settings advanced settings menu and I choose to load it with insmod.
This JPK rom works great for me, so I'll likely keep using it for a long while now that I've got openvpn running fine.
252ae6e655fa08774f32f67dd76dad3a tun.ko
EDIT: the same tun.ko module works for JPM too

Great job!!!
I use vpnc daily, so I couldn't even think to upgrade to JPK without an available tun module.. now I can!
Would you share your .config, so other devs can use it? Maybe we can hope in a Froyo-voodoo in a short time..

I'm confirming that it works.
Here is how I did it (I garantee that THIS IS NOT THE MOST ELEGANT WAY to make it work)
Install Openvpn from Openvpn Installer
openvpn in /system/xbin
route and ifconfig in /system/bin
At this point, Openvpn could connect and create a tun device, but route are not pushed so it's not very usefull
So, I downloaded this version of Openvpn
http://github.com/downloads/fries/android-external-openvpn/openvpn-static-2.1.1.bz2
As superuser
Code:
su
I remounted in rw /system
Code:
mount -o remount,rw /system
I renamed /system/xbin/openvpn into openvpn_old
Code:
mv /system/xbin/openvpn /system/xbin/openvpn_old
I put that new openvpn binary in /system/xbin
I created symlinks from /system/bin/route and ifconfig to /system/xbin
Code:
ln -s /system/bin/route /system/xbin/route
ln -s /system/bin/ifconfig /system/xbin/ifconfig
I also created a symlink os /system/xbin to /system/xbin/bb, just in case
Code:
ln -s /system/xbin /system/xbin/bb
Here we go

config attached, but the config is not enough and it may not be fully correct (it is enough as far as the data structures used by tun.ko are concerned, I checked them all against the zImage assembly). The diff of the v2.1 image, has to be applied too but with DMABOUNCE removed from Kconfig of the subarch of the galaxy as far as I can tell and the placeholder added to struct net_device in their v2.1 diff, has to be removed too. cifs.ko may be more complicated than tun, good luck. Unless you've personal interest to familiarize with the enviroment and the arm assmbly like I had, I would wait the source to released, it has to be released eventually to comply with the GPLv2.

Thankyou Newmail!!
I've tryed VPNC 0.99 and works great!!
You have only to type from terminal: insmod /system/folder/tun.ko
After that you can use VPNC...
I've found an issue with the FQDN of the VPN gateway... solved setting the IP address
Just a question:
when I'll update my JPK.. what I have to do to recompile the tun.ko?
Can you write here the procedure?
Cheers
Paolo

OK, but is the placeholder field at the end of the net_device struct?
If so it shouldn't matter and a module cross compiled from the 2.6.29 source should be OK. The absence of DMABOUNCE shouldn't matter for tun.ko either.
In theory you should be able to clone the AOSP git kernel repo and use that kernel for building a module, as long as the module itself doesn't actually use changes that have been made by Samsung (unlikely).
The .config used probably does deserve some attention though, as you have done.

Glad it works great for you too. So the tun.ko has to be recompiled if they alter .config. It may work but it's not guaranteed. The procedure is nasty and hard to document and I don't have enough time for that sorry. But I'm sure we'll get the source when there will be an official Froyo release that is shipped to all phones so I wouldn't worry.

The .config is the fundamental part, and it may be enough I'm not sure. There was a placeholder was a samsung customization done in the middle of net_device and that was removed in the Froyo ROM (initially I applied it). the DMABOUNCE removal affects the struct device that is part of net_device so a lot of stuff goes off by 4 bytes by tweaking that arch config option. That gets set in some Kconfig patched in by samsung. You're right that probably tun isn't affected by the DMABOUNCE but I tried to get the net_device size right (just in case) and it may affect other net modules.

Hi newmail, thanks so much for the tun.ko file, this is the first time I've managed to get VPNC working on my SGS!! One question though, I find I'm having to run insmod everytime I reboot the phone to make tun.ko available again, does anyone know if there's a way around this please so it stays permanently available? Many thanks!!

@bdl1969
I made a subdir in /system/lib called "modules" and placed my tun.ko there.
Now it's insmodded automagically..

Oh crap, that is bad news.
Then both the DMABOUNCE and the net_device are likely a problem.

hmm I tried and it didn't work for me... are you sure? openvpn GUI runs insmod for me so it's no big deal.

That worked great for me, thanks for the suggestion! The only problem I found was that it caused my Good for Enterprise app to crash so I uninstalled and reinstalled it and then it was all fine. Only problem I'm left with now is when using VPNC, I make the VPN connection fine but I can't disconnect via the app, I have to bounce the network connection (eg. toggle WiFi) to drop the tunnel!

I compiled tun.ko using the 2.6.32 kernel from android git and your .config, but it won't load with dmesg saying "Unknown symbol mem_map". May I ask which kernel version did you use, and what arm toolchain are you using?

Probably you have discontigmem off in the .config. The platform of the galaxy isn't in the android kernel, it's in arch/arm/plat-s5pc11x (it's the thing that sets DMABOUNCE in v2.1 roms and I guess it doesn't on the JPK kernel).
You need to make a diff between android 2.6.29 and their tree, and apply it to the 2.6.32 kernel, then you need to solve enough rejects so that it can build external module. I didn't port the whole diff of course, just enough so make can start with the headers and .config all right. Then I built the module externally (adding the tun/ directory to their modules/ directory) but it should also work with just make modules setting CONFIG_TUN=m if you want to build it in-tree.
It's a bit tricky.. If you really need I can give you the broken diff to apply to the 2.6.32.9 android kernel. That is enough to build some module including tun.ko

Did you find the source now that JPM has been released officially with Kies? I upgraded to JPM now, in the hope we get the source....
BTW, my tun.ko and my rfs_async.ko also works fine on JPM. I don't know about my ext4 build but I assume that will work too.
I used one CSC of this thread http://forum.xda-developers.com/showthread.php?t=802909 and I deleted the KOR /efs/nv_data* created by the JPK ROM (leaving the .nv_data.bak*). So with this combination of CSC from that thread, and MODEM and PDA from the JPM rar, I apparently restored the original product_id (SGSToolbox also says I'm back to the original product_id). Not that product_id matters but I thought I'd try that next time I flashed and apparently it worked fine...

The JPM source was avialable for a few hours on the samsung's site, did grap it. You can find it on megaupload somewhere. I couldn't manage to compile a working module from that source either (it now loads fine, but does a kernel panic when I try to mount a loop device formatted with ext4), but I'm sure that's my fault.

compilng modules for Samsung Galaxy S - config.gz for the kernel is required

I am trying to compile a module for Samsung Galaxy S Froyo kernel. (Actuallu tunnel module - tun.ko)

Unfortunately I couldn't find it under /proc filesystem.
Where can I get it ?
Thanks.

i don have such file but i don have any problem

That's just the gzipped file that shows the compile time options. General setup -> tick "Enable .config support"
Would be great if all the kernel devs would tick this, it'd be a lot easier to build custom ones tailored to just me.

You are mean the "General setup" of the Kernel- config (make menuconfig), right?
The SpeedMod Kernel I'm running at this time has no config.gz, so if I want that file I have to try some other Kernels, hoping that the Kernel- Modder checked ".config support" before building, is that right?

That's just the gzipped file that shows the compile time options. General setup -> tick "Enable .config support"
Would be great if all the kernel devs would tick this, it'd be a lot easier to build custom ones tailored to just me.

i thought the same thing several times in the past

Xperis S: cifs support?

Does XS has a cifs.ko in stock rom to use samba shares? If not, as I assume, is there a way to get this module for an rooted XS? Or are there any custom kernels with cifs support, which I can use on a stock rom?

If you gain root access to your XPERIA S(LT26i) you should be fine.
You can then use CIFS Manager and Samba Fileshaing as is your want.
I chose to use RaymanFX' ELiTE V2 Kernel on my XPERIA S in case that is a factor in making CIFS and Samba share operational, but I don't think it's required.
I'm using CIFS and Samba file sharing without any problems, no *.ko downloads required.

CIFSManager is only a manager, it needs cifs support in kernel.
But I will have a closer look at your kernel, at first sight it looks interesting.

I'm am using an SXAS and I've been looking into this, tool.
After some trying with different kernel modules I downloaded the kernel sources from Sony's developer webpage. And then it became very clear:
Theoretically our 6.2.B.0.200 firmware's kernel has integrated cifs support. The kernel config says so.
So I connected with adb and tried to mount via command line and looked at dmesg. It says: "CIFS VFS: Connecting to DFS root not implemented yet". This means: The kernel should be able to handle cifs, but there is a bug. Either it is the mount utility from the busybox I've installed or it is a bug in the kernel. Since our firmware uses a 3.4.0 Linux kernel and due to some googleing, I assume this to be a kernel bug.
You can find some source code patches in the internet. Maybe I'am patient enough to try building my own kernel.

I did build the kernel with the applied patch, but it didn't solve the problem. I guess I have to do some more research within the kernel forums. So no cifs yet.

Okay, for anybody, who is interested: I have not tried the following using the stock kernel of .200 or .211 since I'm on Forzaferrarileo's JB kernel at the moment. However, after a lot of internet research I found out how to configure the cifs manager app to mount Samba shares again.
Share Path: //<ip>/<share>
Mount Point as you like it
Username as needed
Password as needed
Options: sec=ntlm,iocharset=utf8,unc=\\\\<ip>\\<share>
It appears that the Samba developers changed their mounting syntax. Although the app states to start the share path with the ip, you need the double slash. And although the share path is already defined, they want it again in the options with the unc option. There you need to double all backslashes. If you have spaces in the unc path, use double quotation marks around your path.
Additional info: currently, I'm using busybox version 1.20.2.

Cifs is enabled and the module is built in kernel . Need only right use of cifs manager

Forgot to mention that explicitly, thx.
