[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.

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
The android-linux-stable Telegram channel: https://t.me/alsupdates

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.

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!

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!

That is strange. Will reupload.
EDIT: Done see OP

I've always wondered something, since COS charges money for phone flashing and the only way to get it yourself is to compile it yourself and flash. Once you flash your self compiled build, do you have to build the updates or does the built in updater work?

I didn't see the updater, and even if it was there the keys would not match so you would not be able to update.
Ideally, we would put this on a build server and release the full install and OTA every time there was an update so we would get the updates within a few hours of official. A few changes could be made to either change the updater (if it is there, which I did not see it) or use lineageOS one and modify it to point to the release server.

Yeah CopperheadOS uses the stock recovery iirc. They do it like this to use verified boot iirc. I personally loved COS on my Nexus 5 and missed it on my pixel.

how likely are weekly builds for this rom? also did you find a workaround for the F-Droid extension? I tried manually removing it and disabling it via twrp, but it seems to restore itself or simply refuse to delete, showing as deleted from within twrp

Thank you for building this, I tried and failed miserably. Will flash it today :good:

Fdroid Keys and BuildSystem
Thanks for building.
Please add your keys to the fdroid whitelist.
Could you write/post about your build system?(Like a Howto)?

The fdroid extension needs the keys as I pointed out in the 2nd or 3rd post notes. Regular builds would require a build server but a build server costs money. So, will try to update when I can.

Please see the build instructions in the op that I posted.

Ideally, I would like to make another rom that has the restricted sigspoof added so we could have an option for microg

Meant like a user-doable way until the keys updated, I'm fine with the full screen dialog for now

I have seen and read it before
I setup an build host based on copperheads documentation, I read about the java whitelisting of my keys for fdroid, but the build process itself fails from time to time.
So my question was more about, how did you manage to setup a reliable environment for building. What OS did you use, installed dependencies etc.

What happened to @VR25's modules in the repo?

What happened to @VR25's modules in the repo? Today I looked but his most excellent modules are gone from the repo. Good thing I downloaded them a few days ago, so I'm wondering if there's a reason for the modules' disappearance?

He didn't have time to update them to the new template before the repo purge. I'm sure he'll update and resubmit when time permits...

The modules will be back.

Don't ignore

Sir I am working with a recovery project. I added magisk manager in the recovery by the help of your code. I also gave credit to you. I am asking the permission that can I release the project or I did a wrong step.

[UNOFFICIAL][MAGISK MODULE] Active Edge Mod for Edge Sense Plus - continuation for patch levels 2021-01-05 and later

EDIT: It's too annoying to maintain and edit 6 separate threads. The installer works across all devices, so please visit this post for the latest version: https://forum.xda-developers.com/t/...or-patch-levels-2021-01-05-and-later.4226343/
Thanks!

NOTE: Download link in the OP will install mod for the current patch level down to January 2021. It will detect your current patch level and install the correct file. For earlier system builds from 2020 and prior, please use the official discontinued module on the Magisk Manager repo. I did not clone the entire Active Edge Mod repository; my unofficial repository only hosts January 2021 and later builds.
Changes:
I know, I know... I said I was done with releasing my Unofficial Active Edge Mod installer, yet here's another month's update. I might keep doing it for those that update immediately and want it a bit sooner, so long as it's fortunate enough to happen on a day when I'm able to do it relatively quickly. Since I'm building these anyway and sending them over to the dev, for now, to upload to the official Magisk repo, for now I don't mind also updating it here a bit sooner. Anyway, more on this below and some of the headache involved moving forward...
04-05-2021: Soooo... the script I wrote to churn these out as quickly as possible as Google releases the updates, relied on system image dumps on GitRip... unfortunately the domain was seized by the FBI (lol) and so it looks like the old dumper is no longer updating his Android dumps repo on GitRip. Fortunately, mikalovtch pointed me over to a new source that hosts such system dumps, and I was able to get these done relatively quickly afterwards. OP is updated with the 04-05-2021 installer now!
03-02-2021: Meant to post an update a week or two ago. Noticed the magisk module on the official Magisk repo now says [RE-CONTINUED], so there really isn't much need for me to continue updating this anymore! As a final gift, I ran my batch builder script and built the modded apk's for all variants for the 2021-03-05 patch level, and download link for the module installer is in the OP.
02-02-2021: February 2021 mod is now uploaded. Updated installer is in the link in the OP.
02-01-2021: Modified and uploaded modded SystemUIGoogle.apk files for 3 / 3 XL / 3a / 3a XL to GitHub repository. Updated Magisk installer slightly to accommodate this, and removed a few unnecessary lines. Won't make any difference if you already installed the first release.

ONLY WORKS FOR PIXEL 4 XL "CORAL" AND PIXEL 4 "FLAME"!!!!
(WON'T EVEN INSTALL ON OTHER DEVICES, SO DON'T BOTHER)
tl;DR - A continuation of the "[Discontinued]Active Edge Mod for Pixel devices" Magisk module on the Magisk Module Repository, discontinued and last released for 2020-12-05 patch level. This is simply the same exact mod applied to the 2021-01-05 patch level. PLEASE DO NOT BOTHER THE ORIGINAL DEV FOR ANY SUPPORT - THIS IS AN UNOFFICIAL MOD.

awesome work mate, love this mod. i saw ur post on pixel 4xl forum first and downloaded and flashed that. everything seems 2b working fine! but then i noticed this thread posted seperately on our phone's forum. is there any difference between them?? just wanna make sure that i flashed the rite file. thx again for all mate

Yep, you flashed the right file. Both posts link to the same zip file. The module installer, like the original module, gathers your device information and then downloads the correct file for your device and installs it. Even has an MD5 hash checksum check to make sure it's all good before installing. It was actually a really fun little project to work on, and interesting to see how Jan designed it to be semi-automated, with several fail-safe checks. For example, there's a post fs data script to also disable the module automatically if the user upgrades the system patch level and hasn't yet upgraded the module, likely to ensure the systemuigoogle mod isn't incompatible with the new update and potentially cause issues. Really well designed by the original dev!

How do I actually map it? I have installed on my pixel 4xl but it only opens an unusable google assistant UI.

FoxMMM

The last several versions of Fox Magisk Module Manager has been crashing for me and the app has no way of reporting issues. And the dev is not on GitHub any longer.
Anyone else having the same problems? Are there any other module managers?

Same here.It just started today

A few weeks ago I was having problems with it. The, I saw on the github page that the project was transferred to a different repo with a different developer. So, I installed the build from the new repo and it work for a while and now it is crashing every time I open it. It does have a report feature now though when it crashes.
The old repo is here: https://github.com/Fox2Code/FoxMagiskModuleManager
Scroll down and they link you to the new repo here:
The new repo is here: https://github.com/Androidacy/MagiskModuleManager
The new one seems to still be having some issues though.

Today it happened here as well and the reporting function is outgreyed. Is there any alternative? It showed strange behaviour: it tried (unsuccessful) to use the camera, check the sensors and asked for tracking

It also stopped working for me and gives me an error...
