I need to move the IP in user-space which currently is as a proprietary
module and release the kernel component as GPL.
So for decision making I require this communication.
Any help in terms of ideas or existing solutions would be apprecia
ernel. Is it possible to send event from user-space
to kernel space in -case of fanotify.
I there any other way present which is better than these two above ways.
Any ideas to implement a new mechanism are also appreciated.

You can get the address of the sys_call_table from the /proc/kallsyms and
regarding the read-only section of the this symbol you can re-map the
addresses by making use of vmap api in kernel. This will avoid the need for
the compilation of the kernel. But I would not recommend you to do this.
Their is LSM framework specifically available for this try to see if you
can make use of that.

Now this function gets called in

Hi,
I think you can make use of user-defined signal handlers.

ere are lots of things which need to
be considered instead of setting CPU_THOUSAND_HZ to any particular value,
some of them are whether its multi-core or single core CPU. On multi-core
its quite difficult to get the correct answers, The problems are mentioned
in the above wiki link.

I agree with Mulyadi, you maintain a static global variable (int),
in device_open() ->
if(var)
return -EBUSY
var++
&
in device_release() ->
var--
I think this should do the job.

Hi,
You can get it from following link : -
https://github.com/torvalds/linux/tree/v2.6.12 This is for 2.6.12 as 2.6.11
link is present but not accessible.
You may use 2.6.12 kernel and can get started.

Kern
t node.
So, if for NUMA i mean for DISCONTIGMEM, you want to mem_map ptr, then that
would be maintained per node (per processor), so you need to get hold of all
the nodes in the system, in this way you can complete your assigment.
