2020.2 nexmon

[rootboy01]

hi @re4son
what time the Nethunter's new version will be done ?
i am waiting especially for angler arm64 nexmon libs, because this device like my device (sony xperia z5 compact ( arm64 and sd810 same)
i patched my firmware from: https://github.com/seemoo-lab/nexmon/blob/master/README.md#build-patches-for-bcm4330-bcm4339-and-bcm4358-using-a-x86-computer-running-linux-eg-ubuntu-1604

my device supporting patch:
https://github.com/seemoo-lab/nexmon/blob/master/README.md#supported-devices

bcm43455 7_45_59_16 Sony Xperia Z5 Compact LineageOS 14.1

so just remaining, the libs..

if i use arm64 angler libs, ( future 2020.2 version)
it can be work in my device? i wonder very much..
thanks.

[re4son]

Soon :D

How about you create a NetHunter kernel and I promise to finish the new libs by the time you create a merge request?

[rootboy01]

i created already Nethunter kernel and built for my device and it working succesfull, you know :)
but you said my LineageOS kernel not custom. So you wont accept my merge :D

[re4son]

Yep, I said NetHunter kernel, not LineageOS kernel - We are not that cheap :D
We look after our own first, that's keeping us busy enough ;-)

Why don't you following this guide to create a NetHunter kernel? That's should get you going pretty quickly.

[re4son]

What you've done looks like a very time consuming and convoluted way of installing "Kali NetHunter Lite" :.-)

If you don't want additional wifi device support, injection, HID attacks, etc., then just install "Kali NetHunter Lite" and copy your nexmon files across. That would take less than half an hour.

[rootboy01]

i dont have pc, and i go net cafes for pc sir. nowadays there is corona virus ...
maybe you can create nexmon libs right ? because you have pc :)
also after add 64 bit libs, injections can work right ? ( aireplay-ng -9 wlan0 ) it must say "injections works!"

[re4son]

How about I create that kernel and you help me testing?

[rootboy01]

oww sure sirr :) you give honor.
here time is 03:55 so i must sleep.
maybe after 10 hours later.
i give you basic preferences:


arch= arm64

los 14.1 = https://github.com/LineageOS/android_kernel_sony_msm8994

boot = /dev/block/mmcblk0p29

kernel version = 3.10.84

need wlan0 injections work and maybe hid :) not need for external wifi

[rootboy01]

i used gcc linaro aarch64-linux-gnu latest , this is stable for sony. others giving error.

[rootboy01]

kernel config = arch/arm64/configs/kitakami_suzuran_defconfig

[rootboy01]

sir you will create local.config.example.suzuran right ?

[re4son]

Yep.

This is my standard workflow:


- open "https://github.com/LineageOS/android_kernel_sony_msm8994" in web browser
- Click "Fork"
- Open terminal, cd to build directory, e.g. ~/android
- git clone <remote repo> (e.g. https://github.com/Re4son/android_kernel_sony_msm8994)
- cd android_kernel_oppo_msm8974
- git checkout -b nethunter-7.1
- git clone https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-kernel
- cd kali-nethunter-kernel
- cp local.config.examples/local.config.example.bacon ./local.config
- vi local.config #If you'de like to customize paths
- ./build.sh
- "S"
- "1"
- Choose the device specific defconfig as default config
- Edit kernel config - Only remove "local version", untick "... append version ...", & change hostname to kali
- "2"; build and rebuild with option #3 adding more and more nethunter config items.
- Add one patch after another, build every time with "3" and git commit after every successful build.
- If all configurations and patches applied successfully, do a clean via "0" and a full NetHunter build via "N"
- Git commit of the nethunter_config and kali-nethunter-kernel/local.config, & push everything to the remote repository

[rootboy01]

thanks sir respect.

do you need another info about my device ? (suzuran)
if not i will sleep.
see you after 10 hours sir.

[rootboy01]

@re4son you forked my device's kernel source, thanks https://github.com/Re4son/android_kernel_sony_msm8994

so what about building process ?

[re4son]

@re4son you forked my device's kernel source, thanks https://github.com/Re4son/android_kernel_sony_msm8994

so what about building process ?

Haven't started yet. I'm in the middle of rebuilding my development environment and that'll take another day or two.

[rootboy01]

just boot kali iso sirr :)
thanks, congrats. i am waiting.
wanna ask any questions about suzuran ?

[rootboy01]

@re4son sir what about the last situation https://github.com/Re4son/android_kernel_sony_msm8994

[re4son]

I'm gonna be out of action for a while while I refresh my environment. It's taking longer than expected - maybe a week or two.

[rootboy01]

ok sir. good luck, keep it up..

[rootboy01]

@re4son thanks for quick edit sir, you rock :) https://github.com/Re4son/android_kernel_sony_msm8994/tree/nethunter-14.1?files=1
so what you will change in kernel ? can i learn ? regards..

[rootboy01]

@re4son i can see nethunter defconfig. is there another changes ?

[rootboy01]

Also i see you add oreo toolchain but los 14.1 is nougat.
https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-kernel/-/blob/master/local.config.examples/local.config.example.suzuran

[re4son]

A few patches.
I followed the kernel build section in the NetHunter documentation, starting with this page

https://www.kali.org/docs/nethunter/nethunter-kernel-1-patching/

and working my way through the next six pages.

[re4son]

Also i see you add oreo toolchain but los 14.1 is nougat.
https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-kernel/-/blob/master/local.config.examples/local.config.example.suzuran

It's not really an oreo toolchain. It's an Android toolchain that was released with Oreo to build Oreo and below.

[rootboy01]

oww ok sir i understand you are geniuss :)
can i ask which patches are you added and how you patching ?
i prefer specially nexmon and hid patches you know :)
I am grateful for adding my device..

[re4son]

I used the kernel-builder for patching, following the exact steps as listed in the documentation.
The name of the patches I applied are in the commit messages.

I did not apply any Nexmon patches. Nexmon is not part of the kernel and there are no patches to apply. I will, however, add some helper files to the kernel installation zip later.

[rootboy01]

you mean helper files are 'kalililibnexmon' libs right ?

[re4son]

libs, nexutil, and scripts

[rootboy01]

thanks sir :)
i will ask good question now :D
how can i reduce kernel wakelocks by editing: https://github.com/Re4son/android_kernel_sony_msm8994/blob/nethunter-14.1/arch/arm64/configs/nethunter_defconfig
kernel wakelocks like: timerfd, PowerManagerService.WakeLock, WifiConnnectivityManagerSchedulePeriodicScan etc..
for powersave..

[rootboy01]

@re4son sir also fix false things: https://github.com/Re4son/android_kernel_sony_msm8994/commit/4bf6700debe5c1db9df654cf1337bb819f714ad3

edit: ok sir i see cleanup . thanks..

[re4son]

You really don't want to reduce wakelocks by editing the kernel config. Wakelocks are requested by apps and disabling wifi in the kernel to avoid wifi managers requesting a wakelock is not really a suitable approach.

I'd recommend reading these guides to get you started with optimize your battery life:
https://forum.xda-developers.com/showthread.php?t=1827676
https://forum.xda-developers.com/showthread.php?t=1759541

Having said that, the kernel config you've sent me is optimized for performance and not for battery life. If you are after battery life than I better don't use that.

[rootboy01]

@re4son no problem sir, keep it up :)
i use LKT and Amplify thanks sir.
what time can you submit suzuran with libs into kali-nethunter-devices ?
regards..

[re4son]

hopefully tomorrow

[re4son]

Done:

https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-devices/-/tree/master/nougat/suzuran

Would you mind testing it, please?

And could you also send me a copy of the original fw_bcmdhd.bin and copy of the nexmon patched fw_bcmdhd.bin, please?

Many thanks

[rootboy01]

i thank you sir, i am testing now: https://cdn-16.anonfile.com/V1TbBdvcod/4175d6f3-1588516125/Screenshot_20200503-171705.png

oww sorry, i removed original fw_bcmdhd :D you can get it in kernel source? i can upload patched firmware:
https://anonfile.com/J9X9B6veo5/fw_bcmdhd_bin

[rootboy01]

if all is finish, i will notice you sir

[rootboy01]

sir 2020.2 nethunter-project build py file giving error: https://cdn-06.anonfile.com/zfh0Cavfo4/6714d073-1588516746/Screenshot_20200503-172732.png
i trying master now.

[rootboy01]

sorry its my fault :D

[rootboy01]

sir you need to edit devices.cfg suzuran add arch = arm64 because build downloads is downloading armhf

[rootboy01]

and sir you need to edit boot = /dev/block/mmcblk0p29

[rootboy01]

@re4son sir it giving bootloop.
your compiled Image.gz-dtb has issues. i removed from suzuran directory and pushed my precompiled image: https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-devices/-/merge_requests/229 and it worked.

[rootboy01]

:cry: it giving /usr/bin/sudo not found error :(
i think there is an issue in arm64 minimal tar.xz

[rootboy01]

i used gcc linaro aarch64-linux-gnu latest , this is stable for sony. others giving error.

sirrr you need to use linaro gcc..

[re4son]

What do you mean by latest? latest 4.9 release?

[rootboy01]

https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/

this sir.

[rootboy01]

This ^^^^^^^^^^^^^^^^^^ is not a product of that toolchain:
https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/

Please provide me with a link to the toolchain you would like me to use

[re4son]

I've built kernel ver 1.2 with the linaro toolchain version 5.5 from October 2017.
Please give that a try and let me know how you go.
Thanks

[rootboy01]

oww sir, again bootloop.
i used example_scripts for kernel build.
can you try with these scripts ?
https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-devices/-/tree/master/example_scripts

[re4son]

Would be better for you to take over now. Use the kernel-builder and apply kernel features and patches one at a time, build and test until you found the change that caused the bootloop.

[re4son]

Please raise a merge request once you've built one that boots.
Many thanks

[rootboy01]

but sir i dont have pc enviroment you know :(
please just one time try :)

[rootboy01]

the problem is Image.gz-dtb . can you try build with example scripts :) because i tried with these scripts and it worked.

[re4son]

Please compare those scripts to the kernel-builder and point out the difference that could cause a bootloop. Thanks :)

[rootboy01]

okey sir i using nethunter kex for build procces :) thanks for all.

[rootboy01]

sir remove suzuran from devices.

[rootboy01]

or just remove kernel image sir.
if i can build image succesfully, i will send merge request .

[rootboy01]

@re4son sir can we apply this patch to sony xperia z5 compact ? https://github.com/kimocoder/qualcomm_android_monitor_mode/blob/master/files/enable_monitor_mode.patch
its cooler than nexmon :D
also thanks sir, libs are worked enjections works :)
but when i . monstart-nh
then
nexutil, it says libdl.so not found

[rootboy01]

sir also Nethunter pre4 version has Kex issues.
When i enable Kex, device freezes.
pre3 version is good.

[rootboy01]

sir i think the problem is, using angler device's hid patch.
you patched hid using angler's patch please write patch and apply for z5 compact.
i tried but in chroot, it fails.. out of ram :((

[rootboy01]

@re4son https://github.com/Re4son/android_kernel_sony_msm8994/commit/ebd218ab8a1d2ae60a11dff418d9f8daded1404f

this cause bootloop .

[re4son]

sir also Nethunter pre4 version has Kex issues.
When i enable Kex, device freezes.
pre3 version is good.

Placebo effect. Pre4 is identical to pre3. The reason we have pre4 is so that Android 10 users can upgrade after flashing, which is a requirement to get around the scoped storage issue

[rootboy01]

please sir, try with correct hid patch :)
also what about https://github.com/kimocoder/qualcomm_android_monitor_mode/blob/master/files/enable_monitor_mode.patch :D

[re4son]

please sir, try with correct hid patch :)

Working on it:

https://forum.xda-developers.com/z5-compact/development/volunteers-to-debug-nethunter-kernel-t4094295

thanks sir good idea :)
why you patched z5c's hid using angler's patch?
its %99 bootloop causing i think :)
can you just undo hid patch and try again ?
after your compile procces, i will change my Image.gz-dtb to your new (without hid patch) Image.gz-dtb. (in installer zip)

[rootboy01]

Working on it:

https://forum.xda-developers.com/z5-compact/development/volunteers-to-debug-nethunter-kernel-t4094295

also can you add help for how to patch:https://github.com/kimocoder/qualcomm_android_monitor_mode/blob/master/files/enable_monitor_mode.patch :D

[re4son]

thanks sir good idea :)
why you patched z5c's hid using angler's patch?
Why not? Angler is the name I gave it after I made it apply succesfully on Angler. It's just a name.


its %99 bootloop causing i think :)
can you just undo hid patch and try again ?
I thought you had done that already. Didn't you say that was the cause of the bootloop? Didn't you test it?

[rootboy01]

when i . monstart-nh
then
nexutil, it says libdl.so.2 not found
what cause this errors sir ?

[rootboy01]

when i first try to build image, i used only mac80211 patch and after install there isnt any bootloops sir.

[rootboy01]

why not? because angler and suzuran different devices you know. Sony and Huawei..

[re4son]

why not? because angler and suzuran different devices you know. Sony and Huawei..

Device drivers and kernel patches do not discriminate. Neither should we when we write low level software.

Just open the actual files I patched and learn what those changes do.

ok sir regards sorry for noob :)
can i ask a question.
when you build for suzuran, are you.get any errors ?

[re4son]

Nope. That's why I am 99% certain that the bootloop is not caused by the HID patch but another change I did.
Fits the pattern

[rootboy01]

why i get after . monstart-nh and nexutil: libdl.so.2 not found :(

[re4son]

Not sure. What have you done so far to troubleshoot it?

[rootboy01]

Not sure. What have you done so far to troubleshoot it?

i take an ss:

[re4son]

By troubleshooting i meant what have you done to find the cause of the error?

[rootboy01]

i cant do nothing cause idk about C language :(
i think issue is nexutil library.

[rootboy01]

some nh users have same issue:https://github.com/offensive-security/kali-nethunter/issues/878

[re4son]

Great opportunity to learn about C and to "Try Harder (https://www.offensive-security.com/offsec/what-it-means-to-try-harder/)" :)

[rootboy01]

Great opportunity to learn about C and to "Try Harder (https://www.offensive-security.com/offsec/what-it-means-to-try-harder/)" :)

good advertisement sirr :D
i know the basics of the C
but idk where to start "android kernel hacking"
if you succesfully buid new nexutil library, i promise to you i will be C master :D

[re4son]

I don't have to build a new library. You will understand that when you continue with your troubleshooting.

[rootboy01]

okey sir i will try thanks :)
i understand what you mean.
you did your best, now it's mine

[rootboy01]

@re4son sir i fixed missing lib file errors, thanks :)
so just copied not found libs in /usr/lib/aarch64-linux-gnu to /system/lib64 and done.

but after ' . monstart-nh ' and ' nexutil ',
i got;

nexutil: Segmentation fault

:D help mehh

[re4son]

:D help mehh

What have you done so far to troubleshoot this message?

[rootboy01]

What have you done so far to troubleshoot this message?

searched in google, but no luck..
If i ask you, then there is luck :)

[rootboy01]

also i press:

cd /system/xbin
gdb ./nexutil
run
(no any errors)
bt
(no stack)

and tried for kalilibnexmon.so but there isnt any errors.

[re4son]

why did you copy files from "/usr/lib/aarch64-linux-gnu" to "/system/lib64"?

[rootboy01]

cause missing lib files (e.g libdl.so.2 not found) in usr lib aarc64- folder.
i copied to kalilibnexmon's directory and it worked but now there is segfault :(

[re4son]

I see. What is the purpose of "/usr/lib/aarch64-linux-gnu"? And what is the purpose of "/system/lib64"?

[rootboy01]

sir really is it neccesary for fixing this error ?

[re4son]

Yes. If you want to fix the error then I suppose it is.

[rootboy01]

what am i must do sir, say it regularly please :)

[re4son]

I think you just have to try harder (https://www.offensive-security.com/offsec/what-it-means-to-try-harder/)

[rootboy01]

ooww here we go again..
please sir :(

[rootboy01]

I think you just have to try harder (https://www.offensive-security.com/offsec/what-it-means-to-try-harder/)

oww i think i found.
i must move libnexmon files to /usr/lib right ?

[rootboy01]

sir i am not developer . you are project owner of nethunter, so why you dont want help ? its crazy

[rootboy01]

dear @re4son please remove suzuran image in devices list.
if some suzuran users build nh installer zip for suzuran, users will shock for bricked device. in this world, i am not alone of using suzuran device.
remove kernel image sir..

[sonyvaio]

master @rootboy01 how is the nexmon z5 compact project going? I really hope to use it

[rootboy01]

dear @re4son are you read this: https://github.com/Re4son/android_kernel_sony_msm8994/blob/nethunter-14.1/README_Xperia

sony devices have diffconfig files and you need to export for specific device.
e.g export KBUILD_DIFFCONFIG=suzuran_diffconfig
