Subject: Re: ERROR: Can't hook execve syscall
Hi,
The problem which you are hitting is connected to that:
"the system has Secure Boot enabled,"
Currently, many Linux distributions apply custom patches for better support
Secure Boot scenario. However, among others RedHat developed "kernel lockdown"
patch. As part of that patch they essentially disabled *kprobes, for unknown
to me reasons. LKRG is leveraging *kprobes to put essential hooks and under
that specific patch it is not possible. We are aware about that problem and
around 2018 I've tried to point that, they broke some of the essential kernel
functionality. However, this mailthread didn't go anywhere.
I'm going to poke them again that this became problematic since more people is
hitting this issue.
One way to workaround this problem is to disable SecureBoot. I don't know if it
is possible to disable just pure lockdown without disabling SecureBoot (maybe
it is).
You can also recompile the distro kernel and remove problematic patch:

Thanks,
Adam
