initrd insmod: error inserting '/lib/foo.ko' : -1 operation not permitted

initrd insmod: error inserting '/lib/foo.ko' : -1 operation not permitted

[leo liang]

Hi,

I am trying to add one driver to my kernel.

I have the kernel source and use make all build all the modules and bzImage.

I already have initrd.img in my machine. I extract it to a tmp folder.
Then I copy the driver module into the lib folder. I edited the init
file to insert the module when machine boot. After that, I recreated
the initrd.img by cpio and gzip.

When machine boot,  I got "insmod: error inserting '/lib/foo.ko' : -1
operation not permitted" error.

Did I missed any step? What caused the error?

Thanks.

Are bzImage that you compiled and foo.ko from the initrd.img compiled
at the same time from the same source?

No, the foo.ko is existing module in the initrd image.

Thank you. I think I got the issue.

I should replace all the modules in the initrd.img with the new build.
