Tun.ko in HTC Stock Rom

Hey,
Not sure if this is the right forum or not. But I have tried a few places and ended up with no reply or a dead end so I'm hoping I will actually get some where here.
But is there any way that makes it possible to get tun.ko working on a stock HTC Desire rom?. I have been searching for god know hows long to find any help or instructions on the matter without much help being offered :/
Its because I want to run VPNC on my Desire and I got all the stuff bar tun.ko, so that is the only thing stopping me from going any further and any and all help will be appreciated.
Kind regards.

Yes, you can download the desire kernel from http://developer.htc.com/
You also need the build toolchain for arm processors, find it on http://developer.android.com/sdk/index.html
You need to root your desire, so you can copy files to the system partition. http://unrevoked.com/
The kernel .config file for making oldconfig is , as far as I remember, delivered with the kernel package by htc. If not you can get it from your phone.
Build tun as module, and copy it on yor device.
Hope thats a good quick start for you.

It helped somewhat, althought I am not sure how I actually build something as a module etc considering I dont really have much in the way of linux/unix experience.
But my phone is both rooted and S-OFF.
So considering my lack of experience with these things a more elaborate/comprehensive guide or just the steps I need to reproduce to actually build the file as a module, would be greatly appreciated.

You don't have to build one per say, you just need to find the Tun module (Tun.ko) for your specific kernel.
If you go to the "About phone" -> "Software Information" section, you'll see a Kernel version.
For example, the phone I have is using Kernel 2.6.32.15-gf5a401c - so I have a tun.ko that loads for that kernel.
There's quite a few TUN modules posted on this forum for various versions of the HTC kernels.

If you don't find a module that fits your kernel version , I can build it for you if you want.

My kernel seems to be the same, so would you mind sharing your tun.ko and possibly any instructions on how to get it on my phone and working ?
But my kernel version says: 2.6.32.15-gf5a401c

Here's the tun.ko I made for my ROM:
Tun.ko for 2.6.32.15-gf5a401c
It's not a flashable zip though, you need to push it to your phone using ADB (or use QtADB if you want a UI program to help you).
You need to put it in /system/lib/modules/
To load it, run terminal emulator on your device (it's free on the market) and run the command:
Code:
insmod /system/lib/modules/tun.ko
Although, if you're using a VPN application on your phone, the application might have an option to load the TUN module for you - so the insmod command might not be needed.

Mekrel,
Do you have the "exact" ADB command on hand?. Because I know how what ADB is for, but doesn't know the commands etc by heart

This is the error I get when I try :/
D:\Test\android-sdk-windows\platform-tools>adb push D:/tun.ko /system/lib/module
s
failed to copy 'D:/tun.ko' to '/system/lib/modules/tun.ko': Read-only file syste

Hi!
Seems like there is the same problem on all Android devices. OpenVPN requires the tun.ko kernel module that is hard to get. And it also seems like it must be compiled more or less exactly to much your rom version :-( .
I have a HTC Desire HD running stock rom kernel version 2.6.32.21-gf3f553d [email protected] #1
I have tried various tun.ko modules I have found, but none is comaptible; insmod tun.ko fails.
Questions:
#1 Where can the right version of this magical module tun.ko be found?
#2 Is it hard to compile it for the correct ROM?
#3 How? Isthere any good step-by-step guides.
This could also be a good way to get introduced to compiling kernel modules fro Android devices.

[kernel/rom] cm9/ics build with fixes [02/09/2012 flash.zip update or full rom]

[ 02/09/2012: Screen Flicker / Brightness is an issue. I'll be looking at it. ]
Hi guys,
In an attempt to help further kernel development for the Kindle Fire, I'd like to share my stock defconfig. It's a bit different than the original otter_android_defconfig that g1011999 came up with.
I was never able to get a usable kernel. So I took some time and built up mine.
https://github.com/KFire-Android/kernel_omap/blob/stock/arch/arm/configs/otter_android_defconfig
This kernel builds using the preferred TI compiler used in all of their walk-thrus: CodeSourcery 2010-q1
Moving forward into CM9/ICS, some changes need to happen to the kernel over time. The migration kernel is found in a branch: "L27.13.1-ICS". The END result of this will be a kernel / source that fully support hw codecs for ICS.
[02/08/2012] FLASH ZIP FOR THOSE RUNNING NIND'S BUILDS: http://bit.ly/xYOf0V
The following ROM is built from the sources at GitHub under the KFire-Android org. Many of those files and configurations are the result of countless hours of development by JackpotClavin. I don't want there to be any confusion as to who put in a ton of time getting this to work.
[02/09/2012] FULL ROM INSTALL: http://bit.ly/ygVvQB
Changelog:
- Screen flicker IS an issue right now. Digging into it
- Touchscreen "Slop" set to 16. This should help touches register on the touchscreen.
- Working Data usage stats (xt_qtaguid / xt_quota2 kernel modules)
- TUN, CIFS support
- USB mounting fixes

Thanks Hashcode, currently building a latest ICS version of it.
A little note for those who also want to compile: arm-eabi-4.4.3 and arm-eabi-4.4.0 did not work for me, they ended the compile without any errormessage in the middle of nowhere, arm-eabi-4.3.1 did the job. Took me some time to figure that out ...

If you want to follow a very good step by step guide for setting this up the same way TI (the CPU maker) intended, then follow this:
http://www.omappedia.com/wiki/PandaBoard_L27.12.1-P2_Release_Notes#Setting_up_build_environment
Obviously, that's for PandaBoard, but the Toolchain source and setup are very good.

It goes into deep sleep for me and turning off the stay awake option in settings, developer options, the screen goes off like its supposed to.

Tonight, I'll go back to both of my in-progress kernels and do some testing to see if they'll boot.
EDIT:
Current issues being looked at with this kernel:
- Power off doesn't really power all the way down. It goes to a black screen, but requires long press to turn off.
- Deep sleep isn't happening. The backlight is on a tad while the screen should be off.
But this config is still MUCH better than trying the original.

So does this boot cm7 or anything? My kernel builds boot stock kindle but not cm7
Its something to do with netd/dnsproxyd. Just finding a fix that works is a PITA common issue, but then people dont say how they fixed it..

Right now ive only tested this with CM9

Any chance you're looking into enabling more than 2 touch points in this kernel?

I'm running nind/sitic's cm9-02-04 build with this kernel baked in. I, too, have Stay Awake disabled in Developer Options, and my Kindle is going into deep sleep. I am experiencing the power down issue, though.
It's something I'm absolutely willing to live with for the time being. This is good stuff. Thanks Hashcode!

Well reason I asked was because my kernel wont boot cm7 or cm9. It boots the stock kindle fire os okay. Im getting netd/dnsproxyd errors in the kernel when I try booting cm7.

Right now the difference between this kernel and stock is:
- About 8 ip6 netfilter modules were added
And that's about it.

Are you using the stock ramdisk or the modified ramdisk for cm? I know there must be a difference, as intersectRaven puts out several different variations of his kernel in boot.img form, but I haven't gotten around to diffing them yet

ill look into insectraven's cm kernel thanks!
Edit: That worked! Thanks!
he starts the dnsproxyd differently than what I've seen. But it works!

So I noticed that /mnt/ is mounted read-only which causes issues with apps installing to the sdcard and probably the issue people are having with mounting the sdcard to the computer. Some apps insist on installing to the sdcard (I hate that)
Edit: or do I have this all wrong? Lol I'm no dev remounting it r/w gets the job done.

Is there any websites or anything that you guys would recommend to learn about the Linux kernel and development of it?

Tonight, I went back through and cleaned up my config some more. Removed extra power controls, usb mtp settings and omap mmc host controller (for sd card slot boards).
From my tests, everything deep sleeps correctly and the power off issue is fixed.

[Q] How to build a modified custom kernel for KF HD 8.9"

Hey guys.
I want to build a custom kernel compatible to CM11 roms, which allows to overclock gpu as well as cpu. I used these instructions for building.
My current status is, that i was able to build a zImage with Linaro 4.9.1 from the jem_android_defconfig and the Kindle Fire Android Development repository files. Along the way i noticed, that there are device specific folders for "jem", "tate", etc. and i was wondering if i should use them in any way to build the kernels(?). But i couldn't find any introduction which included device specific folders. What are these folders for?
I tried to use Maromis Kernel (tate) as a basis for my jem kernel (Source) but i have problems to find his build variables, because i lack a general understanding where these are defined (i know about the *.config, but couldt find his modifications there). Where can i find Maromis modifications?
If you in addition know good and recent introductions about kernel building in general, please let me know.
Thanks in advance,
mellhen

fhd kernel ( ZE551 ) & POSSIBLY hd (ZE550) with KVM & Bridge compiled. *need help*

fhd kernel ( ZE551 ) & POSSIBLY hd (ZE550) with KVM & Bridge compiled. *need help*
MODERATOR NOTICE:
All thread posted in the Development section must have a link to kernel sources to meet GPLv2 requirements. Because this thread does not have proper sources linked and because development has stopped, the thread has been closed.
This is my first time working with Android kernels, but I compiled the 2.12.40 kernel source adding in support for KVM ( Kernel supported Virtual Machines, ie running Windows almost full speed ) and Bridge ( to allow qemu-kvm to set up network adapters bridged with the current wifi adapter ).
I tar'd the bzImage & modules, but don't know what to do to make something installable/flashable so will need help on that end of things.
Edit:
I uploaded a new flashable kernel img based off 2.19. This one should support: kvm, bridge and NTFS read/ *LIMITED* write, swap and ignore kernel module signatures. XDA only allows 8mb for .img files, so I tar'd it.
Edit2:
I compiled a ZE550 kernel ( called hd ) and if some brave souls want to try it, I also put together a boot.img.
Edit3:
New fhd kernel has been compiled with additional usb modules. Kernel should now load kvm related modules automatically, so you shouldn't need to use the script anymore.
Anyone brave/crazy enough to try it out? I'm guessing you need an unlocked bootloader & root.
Edit 4:
New fhd & hd kernels for 2.20
Edit 5:
New exfat.ko module

Why 2.12? 2.18 kernel source is available...

That just happened to be the kernel source linked in Android development. If this test works out, I can probably do the same thing with whichever kernel source is available.
Our phones are pretty amazing to be able to compile their own kernels natively on the device.
Sent from my ASUS_Z00AD using XDA Free mobile app

Finally able to compile the 2.18 kernel.. it's a bit weird since it acted like it was missing some files. Untar'd the 2.18 kernel source over 2.12's kernel source and that allowed it compile.
Anyway, it's in the OP called fhd_kernel_20150629.tar and should have KVM ( kernel supported virtualization ), Bridge ( for Qemu-KVM to create bridging ethernet adapters ) & NTFS Read/ *LIMITED* Write.
Once again, it's in the form of bzImage and the modules since I don't know how to replace the kernel on Android devices. ( normally, I'd just make a test linux line in the boot menu for Linux )

One suggestion would be to flash the zImage using
Code:
fastboot flash zImage nameofzImage
or test it using
Code:
fastboot boot nameofzImage
but I dont know if the phone supports the "boot" command.
I´m not sure about the modules either and I can´t test it, as my phone didn´t arrive yet.
Other solution, try this:

Can I ask how you included NTFS r/w support into your kernel? Did you just set the CONFIG_NTFS_FS flag?

TheSSJ said:

Click to expand...
Click to collapse
I added CONFIG_NTFS_FS=m ( you could set to that y ) and CONFIG_NTFS_RW=y in /{working directory}/device/asus/moorefield/fhd/mofd_fhd_diffconfig
when you make the kernel, it's going to ***** about the config files not matching; follow the directions and manually update all of the other config files and it will finally compile.
Building for Android is a pita. )

Well, then here come the disappointing news (I discovered that when I wanted to include NTFS USB-OTG support directly by the kernel for my TWRP and it didn't mount it as R/W):
CONFIG_NTFS_RW is just a partial write support. It won't create files or folders, it can only overwrite existing files and only by the size they currently have
config NTFS_RW
bool "NTFS write support"
This enables the partial, but safe, write support in the NTFS driver. The only supported operation is overwriting existing files, without changing the file length. No file or directory creation, deletion or renaming is possible. Note only non-resident files can be written to so you may find that some very small files (<500 bytes or so) cannot be written to.

Only possibility available is to include ntfs-3g driver using fuse

Yeah, that is a bit of a downer. Now to figure out why nobody finished the NTFS kernel module.

Please keep me posted, I'd like to remove the dependency of ntfs-3g in recovery. I fear there actually is no native support of NTFS (googling was not helpful unfortunately)

1) modify module loading function to ignore module version/magic strings.
2) compile the kernel with toolchain used by ASUS (or close to it)
3) use pre-compiled tntfs.ko from original boot.img
I don't have right now the patch for module loading procedure. Need to check old Galaxy S3/S4 custom kernels source (but it's should be easy to patch by finding error string). In time when exFat module source wasn't available, this trick was very common in samsung custom kernels for exFat support.

Thanks

Wait wait wait. Did I read that correctly? Full speed windows? On the zenfone? I think I just died. Does this mean windows 8/10 or windows xp and below?

I know a bit about android kernel, and i'm thinking about buying this device. Well, i'm going to try to build a kernel for this device as soon as i got this device. One thing you should know is, android is an open-source, so before you uploading your compiled kernel, make sure you have already uploaded the sources

It's only in theory.
In reality, there is no Z35xx support in windows, and i doubt anyone will write drivers by himself (windows isn't opensource). Officially Z35xx is Android-only SoC.

The source is already available, so no worries there, since this is source that Asus released.

For all of the brave folks out there, I was finally able to create a bootable image of the latest 2.19.20 kernel. Anyone brave enough can find it in the OP.
I flashed it and my phone booted up, so that's a bonus.

To be honest? I can't remember since my main focus was getting kvm compiled in.
I've attached my .config for the 20150707 build ( in the boot image ).
I've also attached a screenshot of Windoze 7 being installed.
Commandline for Arch Linux x86_64 to start qemu-kvm to install windoze:
qemu-system-x86_64 -display none -vnc :1,password -monitor stdio -m 1G -smp 4 -enable-kvm -drive file=/mnt/0/machine1.img,format=raw -cpu host -cdrom /mnt/MicroSD/Vcd/en_windows_7.iso -boot menu=on --usbdevice tablet
breakdown of the command line:
-display none = no display, I did this to test the virtual machine. normally, you would probably use -display sdl w/ XServer-XSDL running
-vnc :1,password, This says to set up a vnc server with normal port + 1 ( 5901 ) and you expect a password to be set later
-m 1G, 1 gig of ram
-smp 4, our VM will use 4 cores
-enable-kvm, enable Kernel support Virtual Machines
-drive file=/mnt/0/machine1.img,format=raw, my "disk" file
-cpu host, use the same cpu information
-cdrom /mnt/MicroSD/Vcd/en_windows_7.iso, my Windows 7 install cd turned into an iso
-boot menu=on, enable the boot menu ( hit F12, etc.. )
--usbdevice tablet, Qemu's Vnc server sucks at tracking mouse positions so using tablet mode keeps the mouse pointer .. well on-point

Need help compiling sedikernel (or any kernel)

Hello,
In order to debug the bluetooth problem, I'm trying to compile a kernel for the Captivate Glide. I can't get it to boot properly.
@steadfasterX 's SediROM is the highest-version ROM I know of on which bluetooth works so I've got it installed (version 2.1.2) on the phone.
The steps I've taken so far:
1. I have sedikernel from https://github.com/steadfasterX/kernel_samsung_i927 at commit 088aa4109ad144c583f32da5ffba7bac200f0575
2. I copied /proc/config.gz from a running phone, which contains CONFIG_LOCALVERSION="-sediKERNEL-v1.0", ungzipped it and saved it as .config . Haven't changed anything in it yet.
3. I ran `make CROSS_COMPILE=arm-linux-gnueabihf- zImage` (also tried arm-none-eabi- (both from Debian Jessie) as well as ~/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi- from the NDK)
4. I also made a TWRP backup of the boot partition, and used split_bootimg.pl from William Enck to split it into a kernel and initrd
5. I then ran mkbootimg with the initrd extracted in step 4 and the kernel obtained in step 3 in arch/arm/boot/zImage
6. Finally I flashed this new boot.img onto the phone with odin (Heimdall, specifically)
I see the white "SAMSUNG" logo (which is normal when booting) with a yellow-triangle with an exclamation mark in it. No further boot stage happens (no bootanim from sediROM). If I re-pack the original kernel with bootimg and flash that via odin, then after the next boot the yellow triangle changes into a blue one and sediROM boots correctly.
I'm a bit stuck at the moment, not sure what's going wrong there. Probably the kernel panics for some reason. Is there a way to read the kernel boot messages before android starts? Any help would be greatly appreciated.
Thanks!

Successful!
Thanks to a lot of help from @steadfasterX on IRC I finally managed to compile a working kernel
Here's a list of steps I had to follow in addition to https://github.com/steadfasterX/android_device_samsung_i927/blob/sediROM_CM-ICS/README.md :
1. as discussed on IRC, `repo sync` was not finding a branch. Needed to add
Code:
revision="refs/heads/ics-release"
in .repo/manifests/default.xml in the line with
Code:
CyanogenMod/android_vendor_qcom_opensource_v8
2. I removed the spurious comma in device/samsung/i927/cm.dependencies
3. In device/samsung/i927/, I changed vendorsetup.sh to point to vendorsetup.sh.nopatching rather than .patching (none of the patches could be applied)
4. lunch target was therefore the one with -eng, not -userdebug
5. I installed java 6 manually (didn't have sudo)
6. I installed schedtool
7. I adjusted the path to Java and my toolchain in build_sediROM.sh (taken from https://github.com/steadfasterX/android_buildtools )
8. I downgraded GNU make from 4.0 to 3.81
9. I installed linux-headers and created a symlink from /usr/include/asm-generic to /usr/include/asm
10. I changed the toolchain prefixes in device/samsung/i927/BoardConfig.mk to have 4.4.3 rather than 4.7
11. I built with
Code:
BUILDID=samsung/i927 LOKIFY=0 ../android_buildtools/build_sediROM.sh bootimage
12. I used the original ramdisk I had extracted from sediROM's boot image, rather than the one that was built (we discussed this on IRC too)
This got me a working kernel, yay

its really long guide. You have to replace kernel modules, wifi wouldnt work without modules.
Imho best is compile kernel, modules, replace zImage + modules in this
file and flash from recovery. You dont need to compile whole android just the kernel, you dont need java and other special things, this method is much more faster.

You are right for the kernel but we discussed on IRC to build ram disk too then you need all that stuff but most important he wants to build CM too.
However I'm always a fan of making it right so building a ram disk is the correct way of creating a bootimage. But to start its ok replacing kernel and modules first.

correct way is rebuild whole android, and reflash everything, wipe data/cache
You dont want to make new ramdisk without replace system. System and ramdisk bound together.
I hope you find something, and fix bluetooth or voip audio.
good luck

Well no and yes. I build kernels including ram disk without building system. This is not necessary as long both are compatible.
But you are right that booting fails when system and ram disk are not compatible so the correct way depends
However @uukgoblin I hope you get the fix you want :fingers-crossed:

would you tell me an example when kernel doesnt compatible with ramdisk but kernel does compatible with system?

No no my friend that's not what I said. :cyclops:
I meant if you have CM 9 as system you can build a boot image which includes kernel and a CM9 based ram disk without building cm9 system again. :laugh:
