binder_linux: loading out-of-tree module taints kernel.
binder_linux: module verification failed: signature and/or required key missing - tainting kernel

Now, the build is depend on the "/usr/include/linux/android*", but the files here on the system may be not matched the binder codes.

For example:
I build your aosp 12 binder (checkout to the previous commit) on Ubuntu 24.04 whose linux-libc-dev's version 6.4, it failed:

/root/repos/nixwic/binder-linux/android/native/libs/binder/binder_module.h:48:8: error: redefinition of 'binder_freeze_info'
48 | struct binder_freeze_info {
| ^
/usr/include/linux/android/binder.h:220:8: note: previous definition is here
220 | struct binder_freeze_info {

It seems that the 6.4 kernel headfile has already contained many definitions in binder_module.h of AOSP12...

So I have to copy binder.h and binderfs.h from 5.4 kernel headfiles into the project.

Hi Jeff Kim
I'm following your instruction but there are some errors:

Could you point me out what am I missing?

My kernel version: 5.16.5-051605-generic

Thank you in advanced!
