[REFERENCE] Pixel kernel source with linux-stable (3.18.124)

Introduction
Hello everyone, this is a thread to introduce both users and kernel developers to the concept of linux-stable as well as give developers some tips and a tree to either merge into their own, use as a base, or just as a reference. Feel free to ask questions and enjoy!
What is it?
linux-stable is, as the name implies, the stable branch of the Linux kernel, the base of Android. The phone could not run without the Linux kernel (at least not without reworking a lot of stuff). The Android kernels are based on the longterm stable trees:
Longterm
There are usually several "longterm maintenance" kernel releases provided for the purposes of backporting bugfixes for older kernel trees. Only important bugfixes are applied to such kernels and they don't usually see very frequent releases, especially for older trees.

Source: https://www.kernel.org/category/releases.html
All Linux development happens on the master branch, which is governed by Linus Torvalds. When issues are discovered there, the fixes are applied then backported to these various stable trees for consumption. It is not uncommon for a fix to need to go back a few years.
There is a LOT more information available in the notes repo in the android-linux-stable organization if you care to learn more in-depth: https://github.com/android-linux-stable/notes
What does this mean for me?
If you are a developer, this means you should be merging these changes into your own tree. These are vetted, stable fixes to real world problems and they are being handed out for free. It does not take long to get up to date (as you can just merge this tree directly into your own or do it yourself using the tree as a reference) and once you are up to date, there is usually a release once every two weeks, give or take. I provide a rebuttal to a lot of various complaints here. If you still feel like there is a good reason not to do this, please let me know, I'll be happy to try and debate on it!
If you are a user, it means that you should be looking for and using kernels that have these fixes, as it shows the developers care for your security and stability. The current version for this device is 3.18.100 and the current version upstream is 3.18.124 so all you need to do is go into Settings > About phone and look at the kernel version to know if you are up to date.
How do I use?
If you are a developer, the reference tree is located in the android-linux-stable organization: https://github.com/android-linux-stable/marlin
This can either be merged into your existing kernel tree if you have one or be used as a fresh base. You do not need my permission to use it nor do you need to give me credit (although it would be appreciated).
If you are a user, use a kernel that has the changes added in!
Getting notified about updates
There are a few ways to get notified of linux-stable updates:
The linux-kernel-announce mailing list: http://vger.kernel.org/vger-lists.html#linux-kernel-announce

Hi Nathan, thanks for the code - built the kernel and flashed (wasn't easy at first). All working well, will use it at a later stage when I build the ROM. BTW, I am running the factory image. Credit also to Anykernel for the zip file

Hi, No problem. There you go... Just flash in TWRP and feedback if all went ok

3.18.92 has been merged in.

Hi, thanks for the code, compiled it against linaro 6.4 (built the cross-compiler following your thread). Tested for one day. All smooth. Sharing the job for those who might be interested. BTW, flashed it directly from fastboot....
Code:
fastboot flash kernel Image.lz4-dtb

Hi, added WireGuard support.

Running this now, so far so good! Thanks!
Definitely interested in wire guard, but currently use WindScribe and am not sure how to properly configure it.
Will try and Frankenstein a config file together tonight and report back [emoji106]
Thanks again

Hi, question. Added DSPManager to my ROM and see that it always gets killed. Can you support the idea to build the kernel with
Code:
CONFIG_SECURITY_SELINUX=n
. Will this get me the kernel permissive and any disadvantages with this? I also see that Viper4android needs a permissive kernel.

3.18.93 has been merged in.

Somebody willing to do a build of the update to flash with fastboot?
I would if I could (still learning how to build myself)
Thnx in advance.
Cheers

If it's ok, here is my personal first ever self built kernel from source. It's 3.18.93 and flashable in fastboot (unzip the zip and then: fastboot flash kernel Image.lz4-dtb)
Offcourse thnx to @nathanchance for the source and all the work!
Cheers

Thanks for doing this, very much appreciate it! For some reason though, this prevented my phone from booting. Ended up restoring my boot partition and things are well now!

Github is now opened for the honor play (Devs mainly)

Hey, just opened a github specifically for lineage so if anyone wants to develop for the honor play and create repositories be my guest

Switching to stock is like a bad dream...atleast for me! :laugh:

Ok if anyone is interested i will be uploading the sources to github soon and me and another dev will be working on trying to get twrp to work as well as lineage os 15.1.... sources have not yet come for 16.1 sorry :/ so be ready to flash new stuff when bootloader unlock codes come for our devices in December

Don't have the time to upload sources yet however here is the link and if anyone can upload the sources to github for me i will be very greatful thanks http://download-c1.huawei.com/downl...oadId=99973&version=425859&siteCode=worldwide

Adhell 3 Update

Just downloaded the latest version as needed to update my license key also, but the new key I just generated is not working in the new version, it is asking for a ELM key, I have a KLM like I've always used, which isn't working, adhell gives error 201 when I try to use it. Anyone know what's going on? Do I need a new type of key? I see no options on SEAP to make anything other than the key I have..

See for link to edu key

And more info, last two pages
https://forum.xda-developers.com/galaxy-note-9/help/adhell-3-1-assistance-t3873831/page23

Thanks I figured it out already, never got notification of your reply which would have been helpful haha. But I'm sorted now anyway. Thanks again though ?

Because XDA doesn't provide a convenient way to host and support ongoing source code projects, and there are only 3 of us and only 24 hours per day!
Various XDA threads erroneously deal with AdHell3 as if it were a simple "download and install" app when it's actually a GitLab project which must be compiled by a Samsung Developer. It is not (and cannot legally) be distributed as a precompiled APK, and any such APK that you may find is the sole responsibility of its uploader (and hosting site), in violation of Samsung's policies. Improper distribution of earlier AdHell, AdHell2, and SABS led to those apps getting discontinued at Samsung's request. Furthermore, those APKs must be "patched" to be usable, possibly in violation of XDA's policies.
The AdHell3 project is alive and well, and fully supported in the venues mentioned in my previous post, including READMEs, FAQ, etc. See you there...
UPDATE:
Samsung is not currently issuing any keys suitable for use with AdHell3. Please see our official support areas or at least check out THIS post

[Android 11] Custom Roms Repo - My own builds and tests

First of all, I want to say that I'm not creating a normal rom thread for each ROM I'm building mainly because I'm really bad at post creation. This is just my builds, I got a new computer and felt like compiling. I have been compiling ROMS since my old Xioami Mi mix 1 (Lithium) so I'm kinda experienced. I'm creating my own device tree but for now I'm using sm8150-common (Chandra) and Guacamole (Chandra) and Kernel SM8150. That said I would like to share my AndroidFileHost account, feel free to share, report bugs or tell me which rom you would like .
I'll create a telegram group for discussions and all of that tomorrow.

Sorry but what is the point of this? People want MAINTAINED roms, not one offs that probably won't be updated?

sorry but you should know how things goes, he just started to do anything related to oneplus 7 Pro, there should be a discussion group and after testing and testing various roms if he and his users liked one rom and decided to settle on it he might go and maintain it officially, till that happens it's just a playground

anyone try the Nezuko OS rom yet...currently downloading...and could u look into Pixel Plus or Nitrogen? i think there was Rom with the combo of the two

Your kernel source link is not correct. Are you using the stock kernel? If this is just a modified stock ROM, you can find the stock kernel source here

Is this an Android 9 rom as you menthioned in the title? Gald to see that on Snapdragon S7e. Thanks for your work.

As you still have not posted the correct kernel source, I have closed this thread and removed the download links.
Please be aware that your kernel source link must point to the source code for the OEM kernel if you're using the stock one, OR if you are using a custom kernel, either the source used to build that kernel or its repository. You cannot use the ROM download link as your source.
