Supporting x86/x86_64

[hmtheboy154]

Hi, I just read about the project and I really like it. I am maintaining BlissOS and currently looking for a better root solution than the old Superuser made by koush. But looking at the codes, it seems like the project only support arm64 so far, are there any plan for x86/x86_64 ? I can help you test with x86_64 if you want.

[tiann]

x86_64 is feasible and I will try it, but 32bit arch such as x86 and arm is unsupported

[hmtheboy154]

thanks

[tiann]

x86_64 support is added in 0d8785e, could you test it with the latest commit?

[hmtheboy154]

ok, by the way I can only test SELinux in permissive because this is Android-x86

[tiann]

If it is permissive, may this cause bootloop?

[hmtheboy154]

if you make that hack then it might be, iirc we can't even get SurfaceFlinger running with enforcing

[tiann]

2806601 keeps permissive if it is

[hmtheboy154]

I compiled the kernel module and the app, but the app said not detected......... does that mean I have to compile the userspace su too ?

[tiann]

If you build the manager app yourself, you should also change this to the apk's signature: https://github.com/tiann/KernelSU/blob/main/kernel/apk_sign.c#L115

[tiann]

The signature ensure only the manager can allow/disallow root request, you can try my build(it's the builtin
app-release.apk.zip
signature)

[tiann]

You can modify this line https://github.com/tiann/KernelSU/blob/main/kernel/apk_sign.c#L79 and read the dmesg to get your EXPECTED_SIZE and EXPECTED_HASH.

I tested this and it still not working, but on dmesg it show this

The system doesn't have /data/adb directory?

[hmtheboy154]

It does but it got mounted in this stage

[tiann]

show some load_allow_list open "/data/adb" failed -2 is OK, when /data/ is mounted, it wouldn't show
This log is actually waiting /data to be mounted.

[hmtheboy154]

by the way, a small request
can you limit the manager app to only compile x86_64 and arm64 lib ? to avoid in case the system use x86/arm libs instead

Sure, please try this build: https://github.com/tiann/KernelSU/actions/runs/3709915866

[hmtheboy154]

The app does run but su still not working, here is what I got on dmesg.

[hmtheboy154]

https://github.com/hmtheboy154/Darkmatter-kernel/tree/umbral
This is how I integrate it into my kernel

[tiann]

Does the kernel have CONFIG_KPROBES enabled?

[hmtheboy154]

Does the kernel have CONFIG_KPROBES enabled?

it haven't, and when compile it show this

ld.lld: error: undefined symbol: task_stack_page
>>> referenced by ld-temp.o
>>>               vmlinux.o:(sh_user_path)

[hmtheboy154]

I'm including linux/sched/task_stack.h to sucompat.c right now, I'll see if that help

[tiann]

Maybe you should enable CONFIG_THREAD_INFO_IN_TASK?

[hmtheboy154]

I turn that on already

[hmtheboy154]

It compiled and works perfectly

I also made a PR, can you check it, I don't know if older kernel have task_types.h like this

[hmtheboy154]

guess we should close this issue, x86_64 is working now

[iiowoii3389]

Hello, I see that your Android x86 is using Linux kernel 5.15. Do you have any available source code? The 5.15 kernel compiled by myself does not work, and the system graphical interface does not refresh

Hello, @tiann @hmtheboy154
I made a self-compiled blissos (Bliss-v16.9.7-x86_64-UNOFFICIAL-gapps-20241013.iso), and install it to virtualbox.
Why the manager app only has the home tab, but no SuperUser and Module tabs?

logcat.txt
dmesg.txt
Wish for your help, thks!!!

test #2102

[zsmweb]

@hmtheboy154 working! thks!!!
But i have another question.
Do you have a note for how to porting KernelSU to Blissos that includes all commit?
I build my own aosp with the same kernel with BlissOS (umbral-20230826) .
but enter boot loop!

@hmtheboy154 working! thks!!! But i have another question. Do you have a note for how to porting KernelSU to Blissos that includes all commit? I build my own aosp with the same kernel with BlissOS (umbral-20230826) . but enter boot loop!

I don't build 5.15 anymore so idk, you have to switch to newer ver

There's nothing to do with Superuser it has to do with bootloader unlocked everybody don't even need to be rooted to do that just need to put a loader unlocked on your device and all of it's unlocked cuz when you're turning on your Android you'll say you're unlocked every time you turn on your device this is how you know you're bootloaders actually unlocked cuz it tells you every time you turn on your device if it doesn't then it's not really unlocked that's your issue everybody I'm pretty sure and if you don't believe me I will make a video and post it right here so you all can see this every time I turn on my phone it says bootloader unlocked so why are you almost seeing that if you're not seeing that this software won't work that's correct has nothing to do with super use or anything like that
