Can't flash - No such file or directory about kernelsu

[powellnorma]

Ok, I used https://github.com/FerryAr/e2fsprogs-arm/blob/master/system/bin/mke2fs - I saved it to /data/adb/ksu/bin/mkfs.ext4 - Now flashing the module works fine!

Ok, attached is the full log (tar.gz), after fresh reboot + failed attempt to flash the module.

Btw, I was unable to directly safe/share the log, because of:

[   76.590362] [pid:367,cpu2,logd.auditd]type=1400 audit(1714983679.109:209): avc: denied { open } for pid=3397 comm="Binder:3397_3" path="/data/data/me.weishu.kernelsu/cache/KernelSU_bugreport_2024-05-06_10_21.tar.gz" dev="mmcblk0p56" ino=16258 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:app_data_file:s0 tclass=file permissive=0

Any idea why this might be happening? I am using the stock image, so the selinux config should be normal(?)

Your kernel doesn't work normally:

[   16.928131] [pid:433,cpu4,init]init: cannot execve('/data/adb/ksud'): Permission denied

Check #943 first.

[powellnorma]

Probably relevant: #270 (comment)

[powellnorma]

@tiann

cannot execve('/data/adb/ksud'): Permission denied

Fixed that, the issue still persists though, see new attachment:

Sorry, I don't have time to play with this old kernel; there must be something wrong somewhere else, like an ext4 mount failure, or the file doesn't have permission to create; please add your own logs to see where the problem is.

I see, no problem. I too think there is something wrong in general, because the "file not found" issue appears in other apps too. I might later try to disable selinux / set it to permissive.

please add your own logs to see where the problem is

Ah, you mean recompile ksud to increase the logging level, so one can see exactly what fails? Will maybe try that later, too

I think it is due to missing mkfs.ext4:

HWPRA-H:/ # mkfs.ext4

Please save and check the log.

I wonder what the problem is.. Maybe unsupported options?

Anyone has an idea?

[powellnorma]

Hm, maybe its because that mkfs.ext4 asks for confirmation.. ?

Proceed anyway? (y,n)
