Does anyone have a tun.ko module for the DroidX?
Running update1:
busybox uname -a
Linux localhost 2.6.29 #1 PREEMPT Thu Jul 1 18:18:04 CDT 2010 armv7l GNU/Linux
Running strings and grep on the modules shows:
vermagic=2.6.29 preempt mod_unload ARMv7
I couldn't find Motorola's kernel source for the DX (but the Droid is posted).
Any tips, tricks, or info would be appreciated.
Thanks, Jeb

Well I have a 2.6.29 kernel tree ready to go, but I can't find a kernel config for the DX.
I can't find /proc/config.gz on the system (thanks Motorola...).
Does anyone know the "ARM system type"? I used a HTC config, but the version came out ARMv6, not ARMv7.
For some weeks I've been trying to set up an environment in which I'm able to compile the stock kernel for my LG2X on my own. Following various tips and hints were unsuccessful and several restarts were required until a kernel which was compiled on my own box was running on my phone. Since I had to patch together all the information because there was no complete guide available/findable, I'd like to list here all the steps from the beginning which I had to perform to boot my own compiled kernel. Maybe this is also useful for others. Note: again, this approach is for compiling STOCK kernel sources which are based on the public sources from LG. (The build process for CM is different and cannot be applied to stock kernels)
I began with a freshly installed Ubuntu 11.10 32bit (http://www.ubuntu.com/download/ubuntu/download) running in a VMware virtual machine. In it I entered a shell and switched to root to be able to perform the required actions:
Code:
sudo su -
The next step was to add the package-sources for the cross-compiler toolchain (see next step) and to bring the system up to the latest state.
Code:
add-apt-repository ppa:linaro-maintainers/toolchain
apt-get update
apt-get upgrade
This takes some time but after it's finished I installed the cross-compiler toolchain to be able to compile applications for the LGs ARM platform
Code:
apt-get install gcc-linaro
apt-get install gcc-linaro-arm-linux-gnueabi
After this I've been ready to begin with the source-works. I closed the root-shell and opened up a new one (required to make sure that all paths are correctly set and recognized again). Test it by executing
Code:
arm-linux-gnueabi-gcc --version
When this executed without error I started with downloading the sources for version 20q from http://www.lg.com/global/support/opensource/opensource-detail.jsp?detailCustomerModelCode=LGP990 into a new directory.
When the file 'LGP990_Android_Gingerbread_V20Q.zip' had finished downloading I unzipped the complete package by
Code:
unzip LGP990_Android_Gingerbread_V20Q.zip
resulting in three files. A README, one .tar.gz with the ROM sources and finally one .tar.gz with the kernel sources. To unpack the kernel sources I issued
Code:
tar xvzf P990_Stardop_IFX_GingerBread_V20Q_KERNEL.tar.gz
and the complete LG 20q kernel sources were finally located in a new 'kernel' subdirectory.
The kernel sources themselves are not yet ready to be compiled. This is because LG most probably has a different/special build environment and our standard environment produces errors and unbootable kernels. Some patching is required to succeed to a running kernel.
Firstly the compilation options for the wireless module have to be tweaked as the default settings break compilation at some unused variables in the source. This is set to be just treated as warnings for the wireless-module by applying following patch:
Code:
diff -u -r original/kernel/drivers/net/wireless/bcm4329/Makefile kernel/drivers/net/wireless/bcm4329/Makefile

We're not finished yet. We've to create the correct kernel configuration and (again) apply some patches. I'm not so sure about these changes but the kernel refused to boot on my phone without them. It is again provided by spica1234 and contains a number of changes. I did not research which of these changes allowed to boot since most of them are generally useful and I didn't do the work trying them out one-by-one.

After these patches, were finally ready to compile the kernel
Code:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- STAR_TMUS_REV=TMUS_10 TARGET_STAR_HWREV=TMUS_E TARGET_MODEM=ifx
Now go grab some coffee. This takes a while. When it's finished, the compressed kernel-image is found in
arch/arm/boot/zImage
For the experienced kernel-hackers this might be enough. It wasn't for me and I wanted to have it easily installable like other kernels from the forum. So I downloaded a kernel zip package, eg. the one from spica1234 at http://forum.xda-developers.com/showpost.php?p=18253696&postcount=1
Any version will do as long as the kernel is contained in a .zip archive and installable via CWM. In my case I downloaded the kernel zip in a new directory 'build' and unpacked it.
Code:
unzip HP_2x_RC12-RevOTF-PRO.zip
This creates the subdirectories 'data', 'kernel', 'META-INF' and 'system'. Here we now have to replace the kernel and the kernel-modules with our self-compiled versions.
Code:
cd ~build/kernel
rm zImage
cp ~kernel/arch/arm/bootzImage ./zImage
cd ../system/lib/modules
rm *.ko
find ~kernel/ -name "*.ko" -exec cp '{}' . \;
cd ../../..
One last step, creating the zip which carries the new kernel:
Code:
zip -r -FS new_kernel.zip data/ kernel/ META-INF/ system/
This new_kernel.zip can now be flashed with CWM and should boot without problems.
For easier usage, I've attached the three patched files in the build_set.zip attachment so you don't have to patch the stock files by hand. Just extract it in the kernel directory and overwrite the existing files.
I hope I did not make any error in the compilation of this information and that it can be helpful for the interested reader.
Thanks goes especially to spica1234 and the material which he provided me to come through to a successful boot.
Very good explanation. I wish such useful info available b4 an year for me while i published 1st kernel at samdroid for my older device

Bloody hell! I never realised it took so much to simply compile!!!! (I build JEE systems at work, but we scripted most of it, stuff that used to take a day and half now takes a few minutes).
Excellent guide Kosi! I'm a linux and kernel n00b and I understand your instructions pretty well.
Ubuntu 11 is not the best choice though I currently use it myself. v11 can cause problems, especially when not compiling kernels but compiling Android ROMs.
Ubuntu 10 is the better choice.
Also there is a VMware Android Developer Environment available for download, providing nearly all the necessary tools for compilation preinstalled and set-up.
http://forum.xda-developers.com/showthread.php?t=1386918
You can compile your kernel directly in the virtual machine p.ex. on your Windows 7 PC. That's the way I do it for my kernel. VMware Player is available for free, so you can just run the image.
Also install VMware tools, so you can set up a directory for exchanging files between your Windows Host and the virtual Machine Ubuntu. In this directory I usually paste the compiled kernel for further use under Win7 (making the CWM update ZIPs).
Just note that you should have a dual/quadcore CPU strong enough to host the linux and compile the kernel in an acceptable time (usually it takes me 1-2 minutes for complete kernel compilation under virtual machine ubuntu using -j24 option on make).
Can u guys add a bit in this tutorial, example, at which file / folder need to edit for OCUV, add swap function, enable ext4, etc.. seriously like this thread..

As the topic of this thread is just how to get the stock kernel compiling I won't step into modifying it. Please open a separate thread for that.
Small hints though, OCUV requires deeper code changes, swap and ext4 can just be enabled in the kernel config.
Hey,
I follow the guide, but ubuntu (11.04 64 bit) doesn't find the pack
Code:
apt-get install gcc-linaro
so I can't install the pack
Code:
apt-get install gcc-linaro-arm-linux-gnueabi
Edit: With Ubuntu 11.10, it works.
Has anyone compiled and booted a kernel successfully with this guide? Can't get mine to boot, so before I look any further I'd thought I'd check if anyone else has gotten a workable kernel out of it.

Ubuntu 11.xx is still a good choise if you want to build ROMs it is very easy to set it up (it is just one step more then on 10.xx)
i also use ubuntu 11.10 and it is working fine for me with building android ROMs
and of course it can take 1-2 minutes but it also can take up to an hour for a kernel to compile
it all depends on how good your computer is
on my home computer i build a kernel in a matter of seconds (clobber builds)
but when i am at my girlfriend my build (also clobber) on her craptop will take up to 20 minutes
nice guide kosi2801!

Yap. This
Code:
arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.6.2-14ubuntu2~ppa1) 4.6.2
to be specific.
Trymhanson, Try to downgrade with 4.5.3. 4.6.2 is causing this unable to boot issue which was not happening earlier with 4.6.1
try this
apt-get install gcc-4.5-arm-linux-gnueabi
apt-get install g++-4.5-arm-linux-gnueabi
rm /usr/bin/arm-linux-gnueabi-gcc
ln -s /usr/bin/arm-linux-gnueabi-gcc-4.5 /usr/bin/arm-linux-gnueabi-gcc
Thanks, that did it. I also had to change the -Ofast flag back to -O2 as -Ofast wasn't recognized by the 4.5.3 version. So now I'm thinking maybe the -Ofast flag was to blame, so I'll try a fresh 4.6.2 install with -O2. Thanks again.

no may be ofast is not to blame but 4.6.2. Ofast was introduced with 4.6.0 and doesnt work with < 4..6. 4.6.2 doesnt even work with o2. And IMHO kernel compiled with 4.5.3 ismore stable

Leave this 3.0.8 kernel info just for historical purpose:
I try to build Galaxy Tab 2 kernel from source for stock 4.0.4 firmware but no luck so far.
Source from http://opensource.samsung.com/ without modification, using the latest Sourcery G++ Lite: boot failed!
Souce from Samsung without modification, using Sourcery G++ Lite 2010q1-202: kernel boot but no hardware accelerated video, camera and video not working!
Source from codeworkx without modification: kernel boot but incompatible pvr driver, stuck on Samsung logo!
Source from codeworkx without modification, vendor blob updated: kernel boot but unstable graphics, gallery, camera and video not working!
Source from codeworkx, pvr driver revert back to Samsung source: kernel boot but no hardware accelerated video, camera and video not working!
Source from codeworkx, pvr driver revert back to tuna ICS source, using tuna ICS vendor blob: kernel boot but no hardware accelerated video, camera and video not working! Better 3D graphics performance.
UPDATE:
Soft decoding video player (MoboPlayer) work.
UPDATE 2:
Found the problems! libion.so and libtiutils.so not compatible to the old kernel source. Thanks for codeworkx, tracing his work on CM9 point me out to the proprietary libraries.

When you compile a kernel, some drivers should have also been compiled and their locations should have been displayed on the console. You should copy those drivers to a proper location, I copied those .ko files to /lib/modules of the ramdisk when compiling a P3110 kernel.

Yes.
Conclusion:
Using Galaxy Nexus PowerVR kernel driver and blob build [email protected], we got better 3D performance on stock 4.0.4 firmware but lost hardware accelerated video (base on Antutu result: 3D = ~1030, fps 40-50). Video failed to play, camera failed to open. So, the best kernel for user experience (slower 3D but smooth 2D) is 3.0.8 from 4.0.4 firmware for now.
Now I'm sure, Samsung has been making changes in the 3.0.8 kernel for ICS 4.0.4 but have not released it to the public. Please help me to write a petition for Samsung since my English not good enough :crying:
Last night I tried to rebuild the kernel from source (again) and this time set the kernel version exactly same as stock 4.0.4 kernel (3.0.8-583493-user). Using kernel source from Samsung, codeworkx's patch applied except tuna pvr driver patch. Keep the stock kernel 3.0.8-583493-user modules in /lib/modules and then rebuild the boot image. Damn Samsung, hardware accelerated video still does not work! 3D performance slower than tuna ICS pvr driver but 2D experience as smooth as stock 4.0.4 firmware.
/system/vendor/firmware/ducati-m3.bin not loaded properly by the kernel. No rpmsg-omx0 and rpmsg-omx1 inside /dev .

Solved!
Found the problems! libion.so and libtiutils.so not compatible to the old kernel source. Thanks for codeworkx, tracing his work on CM9 point me out to the proprietary libraries.

You really did an excellent job with TW kernel.
Is it possible for you to compile an updated kernel for CM10.1?
Stock CM10.1 kernel does not support overclock.
cmenard AOKP kernel works well with CM10.1, and it supports both CPU and GPU OC, but it is based on the old source, with 690mb available, compiled for 4.1.2
It would be awesome if you could update one of those 2 kernels.
First page updated, including the patch!
- omaplfb now integrated into kernel
- overclock code updated, lock CPU @ 1.008GHz on boot
Hey guys are there some existing cisf module to mount cifs and nfs partition on the Galaxy Tab 2 3110?
I would like to mount my share (not for copy) but for directly playing movies. I did with some old pads but i don't know if this module are available for the Tab 2

KK-Boot has it.
First page updated, kernel source and patch.
This is an EXPERIMENTAL Kernel that continues the work of @pengus77, but with some additions i make. That means a huge thank to pengus77! Please check his thread http://forum.xda-developers.com/showthread.php?t=2097788
This kernel is completely based on his latest release.
This kernel only supports newbl and will only work on roms with 3.1 support (these are atm only 4.4 (aka KitKat) Roms and tonyps TheRom that is compatible with the 3.1 kernel
Features:
Features from the kowalski kernel:
3.1.10 Kernel Version
bcmdhd wifi driver
Dynamic FSync
Overclock to 1.5 GHz (Not all phones work well with 1.5 Ghz!)
Undervolting
MultiCore Sched PM
Auto Hotplug
Fast charge
Wifi PM
and many more ...
Features added by me:
PKSM as enhanced KSM module
Built in ZRAM Modul (that makes it possible to use the android default zram solution)
Possibility to use deferred_timer for (P)KSM
0, 16 or 32 MB Ramhack
Support for extra free kbytes tunable (more a ROM dev feature)
Custom vibration force/strength through sysfs
120MHz and 168 MHz frequencies for more battery savings during wakelock
Known bugs:
Camera Bug
Gyro does not work properly
If you want to report a new kernel bug, you must describe your problem in detail, post your kmsg and last_kmsg (if available) (you can found them under /proc/kmsg and /proc/last_kmsg) otherwise the rule is: no log = no issue
Downloads:
This is more a personal kernel build. I have built these kernels for weeks for myself and used them in private. Now i just want to share them with you guys!
You can download the kernels here: https://s.basketbuild.com/devs/firtecy/p990/kernel/3.1/ They are labeled like this: firtecy_kernel_X-N.zip where X is either exp for an experimental kernel release and stable for a stable kernel and where N is the build number (this number is always incremental!)
Sourcecode:
You can find the sourcecode at github: https://github.com/Firtecy/kowalski/ the branch is exp. The config file is: "kowalski_defconfig"
The intention of this thread is to continue the 3.1 kernel development pengus started. Development related questions or discussions are appreciated
Have fun!
And to quote pengus77:
On a side note... i'm not really responsible if you decide to test it and your phone melts... right?
Thanks to:
@hjunii for bringing up 3.1 Kernel
@pengus77 for the kowalski kernel

Kernel Special Features:
Version Information
Status: Beta
Current Beta Version: 3.1#5
Beta Release Date: 2014-08-25
Created 2014-10-31
Last Updated 2014-10-31
Changelog:
firtecy_kernel_exp-5 - 25.8.2014
Added intellactive governor (thanks to @faux123) and powersave
Some bug fixes
Added sync framework and exfat support (but not active for the moment)
Added a "kowalski touch driver" and dt2w files (since they are not stable enough for now, they are disabled)
The reason why I disabled those things is that I didn't had the time to test them. If you want to test them you have to build your own version. Especially for other developers that can be interesting.

firtecy_kernel_exp-4 - 25.6.2014
minor updates/fixes from other kernels
Added the min screen on freq back
Added a sysfs attribute to change the min screen on freq
when disabling pksm, it will be disabled completely
Screen on min freq
If your screen is on, this frequency is the lowest that will be used. If your screen goes off for whatever reason the cpu will go to the normal min frequency.
Note: It seems like 120MHz and 168MHz are stable even for screen on, but since there was the question if i can add it, here you go:
How to change the value:
Code:
echo [value] > /sys/module/cpu_tegra/parameters/cpu_screen_on_min_cap
You have to use a value that is in the frequency table, but you have to echo the frequency in KHz, so 120MHz -> 120000KHz:
Code:
echo 120000 > /sys/module/cpu_tegra/parameters/cpu_screen_on_min_cap
This option does not stick after a reboot
According to @BS86 this release should be more stable than exp3 and thanks for testing!

firtecy_kernel_exp-3 - 13.6.2014
tons of updates to zram/zcache (picked from faux123 tegra kernels)
crypto: added optimized AES and SHA1 routines
added permission checker for binder IPC
tegra video driver updates
Fixed the voltage table -> all values below 770 MHz are not supported by the regulator chip (thanks to all who helped researching! )
Click to expand...
Click to collapse
firtecy_kernel_exp-2 - 8.6.2014
Added the possibility to change the vibration force (or vibration strength)
Added 120MHz and 168MHz as cpu frequencies
Enabled 600 mV as lowest undervolting value (undervolting is very dangerous if you go too low! Better stay at defaults)
Fixed a nvidia or lg cpu derp.
For security reasons it is not possible that the cpu will go underneath 216MHz when screen is on!
Option to use: No ramhack, 16Mb Ramhack or 32 Mb Ramhack!
Vibration force:
to change the vibration force echo a number between 0 and 127 to /sys/module/tspdrv/parameters/vibration_force. Where 127 is the highest and the default. 20 seems to be the last noticeable value.
Code:
echo [force] > /sys/module/tspdrv/parameters/vibration_force
This option does not stick after a reboot. Rom support will be available (hopefully) soon. I'm preparing a patch for tonyps Rom, so that it is possible to change it in the Rom settings.
120 and 168Mhz:
These values are useful for the case where the phone helds a wake lock. This means because of the wake lock it won't enter deepsleep. The phone would run at 216MHz even if it isn't needed. Running at 168Mhz or even 120MHz should result in a better battery life.
If you experience any problems, try to raise the voltage at this frequencies to a higher value and test again. If it is still unstable report it (with a description of the problem) and change the minimum frequency to 216Mhz.

firtecy_kernel_exp-1 - 1.6.2014
Initial release
Base source: kowalski kernel
Added built in ZRam (no need to use zram.ko for longer)
Added PKSM as replacement for ksm (http://code.google.com/p/pksm/)
Enabled deferred timers for pksm and ksm
Notice: Since there is no ksm available, but pksm you will not find the options for ksm in any app. All configurations are no longer under: /sys/kernel/mm/ksm/ , but under: /sys/kernel/mm/pksm/
To deativate pksm run this command as root:
Code:
echo 0 > /sys/kernel/mm/pksm/run
This option does not stick after a reboot

How to build your own kernel:
You need a Linux PC with either 32 or 64Bit. I'm using Linux Mint Debian Edition 64Bit. And you will need the following packages:
build-essential kernel-package libncurses5-dev bzip2
For example to install them run:
Code:
sudo apt-get install -y build-essential kernel-package libncurses5-dev bzip2
Hint: If you run into troubles with installing packages, check this post
1. Create a new directory for your kernel building (for example: ~/kernel_p990)
Code:
mkdir ~/kernel_p990
2. cd to your kernel dir
Code:
cd ~/kernel_p990
3. Run this command to download the source code for compiling:
Code:
git clone https://github.com/Firtecy/kowalski
4. Now we need to download the toolchain for compiling: Download it from here: http://www.linaro.org/downloads/ under the Bare-Metal section. It is labeled GCC ARM Embedded. Version: 4.7-2013.q3 ; Release: 13.11
5. Now extract the toolchain to a new dir, for example: ~/kernel_p990/toolchain
6. Now we have to define some values for the build enviroment:
Set the CROSS_COMPILE var to your path where you have downloaded your toolchain. For example:
Code:
export CROSS_COMPILE=~/kernel_p990/toolchain/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-
Notice at the end you find this prefix: arm-none-eabi- this is not a dir, but the prefix for all files inside the bin directory(for example: arm-none-eabi-gcc)
7. Set the architecture (processor architecture) for which the kernel should be build. So in our case arm:
Code:
export ARCH=arm
and
Code:
export SUBARCH=arm
8. The next step defines the configurations for the kernel (in this case the configuration is named kowalski_defconig)
Code:
make kowalski_defconfig
Notice: this takes the configuration from the file located under arch/arm/configs and will write it to .config
9. Now we can finally build the kernel :victory: Run:
Code:
make
You will find the kernel under: arch/arm/boot/zImage. You just have to copy the zImage and replace the one found in the flashable zip (e.g. my downloads) under kernel/zImage with your own.
Troubleshooting:
Before you can build or run any from step 8 or 9 you have to make sure that all three vars are set correctly (so ARCH, CROSS_COMPILE and SUBARCH). You can check it by running:
Code:
echo $ARCH
for ARCH (for CROSS_COMPILE and SUBARCH it is the seem, but you have to change the name)
If they are not set correctly repeat step 6 and 7.
If you get a compile error first try to run:
Code:
make clean
and try to build the kernel again.
How to diff 2 files or directories in linux
If you are running linux and have two files on your computer and you want to find the differences you can run the diff command in the terminal.
Let's say you have a file "hjunii/traps.c" and "kowalski/traps.c", this is how you compare them:
Code:
diff -u hjunii/traps.c kowalski/traps.c
The command will compare both and will print an output to the terminal that will be similar to this:

Then I am sorry, but it is not compatible.
The 3.1 kernel differs too much to be compatible with ROMs that are build for an 2.6 kernel

Oh my God, amazing! Finally some serious development! Great work Firtecy. Time to bust CM11 back on my device and try this ramhacked wonder
Oh...i see...this why no ksm settings
Btw...i would suggest a higher ramhack like 32mb like m1 ramhack...but this kernel works great so far...just classic low ram problem exist (well...obviously) need to set an aggresive value (i'm using swap without zram)
Do i need to post a logcat?

The first change:
Okay since there was the wish that there should be a 32 MB ramhack version and the poll showed the same i built one. You can find it at my basketbuild https://s.basketbuild.com/devs/firtecy/p990/kernel/3.1/.
So the 32 MB Ramhack version is labeled: firtecy_kernel_exp-1_32MB-RH.zip and the previous one is labeled: firtecy_kernel_exp-1_16MB-RH.zip
I have flashed it and in the settings app, I had 372MB available (Settings > About)
The second change:
Since i have been asked to explain how to build my kernel from source code i wrote a small how to in the third post of the thread. Check it and maybe try to build it for your own.
If you wish i can also write how to change the kernel by your own. (So add new stuff or something similiar)
Great job firtecy...downloading asap
--------------------++-
Very fluid ui with 32rh and with performance control app i can set lmk on boot (dunno..the one come with rom 0527 always reset after reboot)
So far...no bugs for me (except known bugs)
Btw i'm using swap only..no zram but zram works too (i turned it off)

I haven't got random reboots or always waking phone in fact on 3.1 kernel there's a bug for waking phone (need press power button twice or thrice)
Maybe your memory full ocupied and still lot queued job to do...that's sometimes happen to me...that's why i need to set lmk a bit aggresive...
Well as dev always said...log or it's not happen

Any kind of OC is really dangerous on Galaxy Tab2. While OMAP 4460 has a built-in temperature sensor, OMAP 4430 doesn't have one. Nothing stops it from overheating...

[#WARRANTY]
It is difficult to update all Roms frequently, and it does not always makes sense to compile, download and flash a whole rom, if only some kernel changes are applied.
This kernel will include changes before i add them official to our kernel source (most of the time security bugfixes)!
Android 5.1 and Android 6.0
This Kernel works on all Android 5.1 and Android 6.0 Roms for espressowifi and espresso3g.
Android 4.4
On Android 4.4 we need a different kernel, 4.4 Kernel includes "KitKat" tag on zip name.
What else to say
Kernel compiled using GCC 4.8
Anykernel based on Anykernel2 by @osm0sis ( https://github.com/osm0sis/AnyKernel2 ) - it will dump your boot.img and replace the zImage and add proper kernel modules.

DEVICE SPECIFIC ANYKERNEL
Edit 02.05.2020
Latest device specific AnyKernel-Zip can be found here:
https://forum.xda-developers.com/showpost.php?p=79259009&postcount=204
Please note: our kernel detects your Tab2 variant at boot and chooses the right driver and config for your device! In some cases (e.g. if the mainboard or the screen got replaced) your device variant isn't detected right and it will use wrong driver!
I am not sure how many user are affected, but in such case we can skip the intelligent board detection and hardcode the variant.
Attached device specific kernel should work on all unified espresso/espressowifi & espresso3g roms from Android 5 up to Android 7, for Android 4 Roms please use the "kitkat" version.
Feel free to buy me a coconut water if it helped you to keep your Tab still, after many years, almost up to date.
UPDATE AnyKernel-2016-10-21
- Update the ext-csd.rev check for eMMC5.1 (fixes emmc detection for some tab2)
- CVE-2016-5195
- CVE-2016-6828
- CVE-2016-7042
thanks andi.
working nice on my own builded aosp-6.0 10/16

Hi Android-Andi.
Has this kernel the OPTION (or plan to enable) to overclock ?
Thanks.

No as mentioned in first post! Move out of this thread if you are not able to read first post.
~ All my work, news etc. on http://andi34.github.io ~
Guys, if you don't read the OP the thread will be closed and you can take care about a security patched kernel yourself.
Source is available on github, add everything you miss by your own and stop spamming this thread!
Edit: everyone not accepting the forum rules will be reported!
Edit2: Thanks @ Moderator for the post remove / thread clean

It is quite funny making noise about a bug which existed 9 years now.
1. It is fixed on my kernel as mentioned on 2nd post (wonder why i spend time doing it)
2. I don't see an issue on custom roms (can be fixed within 2 minutes), i would worry about android by your Manufacturer (on all devices).
On android we change the wheel: no central updates like on linux or windows - it is up to your manufacturer to update your device and there's a lot of security issues fixed by google on android every month (and sure, some kernel side too). How many stock updates you get? 1, maybe 2 within 1 year and support drops after that.
To be true: i am not sure if my next device is an android device:
On my g4 i am on stock rom and LG cares 0 about it (Security patch level 2016-07-01... I waited 6 or 7 month to get that update and it was already 1 month behind).
If manufacturer don't care about theire flagships, what else can we do? Flashing custom roms? Right works, but on my daylie driver i don't like to be a flashahollic... I am more thinking about using a different OS.
You should think about my words and don't care about a already fixed security issue

Hi Andy,
First of all, many thanks for all your work! I´m using your ROMs and kernels since Slimkat and all are great!
I also do my best colaborating with the translating team of CyanogenMod and SlimRoms (Brazilian Portuguese).
But now I would like to compile a kernel bymyself, to patch the CVEs, changes I like, etc.
If you have time, can you post here the steps you do to compile the Anykernel?
Don´t need to waste time explaining the things, just post the step-by-step commands (git clone, makes, ADBs, etc) and I will do my research, ok?
Thanks in advance and greetings from Brazil!

Oh and @Android-Andi just a small request , change the color of the text for ""CVE-XXXXXYYYY" DOES NOT AFFECT" because This colour is hard to read on the screen .

Thank you very much, Andy!!!
It´s more than enough!
Everything else, I will read documentation at the Internet, but this is a great starting point for me.

Dont use it if you dont want it!
It is for the kind of people who want a secure kernel ... more secure than the one given by samsung (I dont remember the last time they sent us a patched kernel update ...or did they !)
Nearly all the device I own are waaaay too insecure (be it my router (its also a linux system) , phone Landline TV ...) except for my 4 year old tab all thanks to Andi ! Respect it
Besides OP is doing all this as a hobby and not for your or my benefit.
Stop spaming this thread ! Please READ
Please respect the following 2 points
No feature requests!
Overclocking will never be added here!
