The 4.8.0 series of the kernel is not supported in Ubuntu any more.

subhash (subhash090) said : #4

I did not got clear details and clarification on this.
I have got the 4.8.0 kernel series downloaded from the ubuntu source repositories.
i am looking to hook some system call table and it happing in 4.4.0 series kernel and i have issue while same steps to hook the system call table not working on 4.8.0 series kernel on the same system. Something has changed in kernel symbol table loading in 4.40 series to 4.8.0 series.
I appreciate if any one drive me to right direction at least. kernel does not support does not bring any point here.

Manfred Hampl (m-hampl) said : #6

The 4.8.0 kernel version is obsolete in Ubuntu.
You cannot expect any answer on it any more.

subhash (subhash090) said : #7

Then how about 4.9.0, 4.10.0, 4.11.0 and 4.13.0. I have facing the same issue with all the kernel.

Manfred Hampl (m-hampl) said : #8

I am not sure what you intentions are.
Kernel address space layout randomization is a security feature.
Do you want to request that it is removed from the Ubuntu kernels?

Manfred Hampl (m-hampl) said : #9

Subhash, why have you replaced the question description and title by nonsense?

The original contents were:
kernel version 4.8.0-58 having kernel randomisation which does allow system call hooking

we have a kernel module which hooks kernel symbol table and replace with the customise system calls. We are able to do the same with the kernel 4.4.0- series but once tried with the 4.8.0 series we have intermediate kernel panic or system does not get booted up once my kernel modules get installed.
I have a observation in the kernel configuration, On 4.8.0 series we see kernel randomisation option is enabled with respect of 4.4.0 kernel series.
Is this is the reasons ? or Do you guys have any idea why this behaviour is showing on the 4.8.0 kernel series.

Any suggestion will appreciated
