I'm looking for a way to store variable,value pairs in the kernel at
runtime. For example, I need to able to execute a command from the
user-space and say
my-kernel-set myvar "arbitrary value"
This should create a variable in the kernel space with the name "myvar"
and set its value to "arbitrary value". Later, I want to be able to load
a
kernel module, that uses one of these variables. For example a kernel
module may make a call to the api as:
my_kernel_get("myvar", buf, sizeof (buf));
Also, I want to be able to do:
my-kernel-get myvar
from the userspace.
What I want to know is that if such a mechanism already exists in the
kernel or not? If not, do you people see if wanting such a module is a
valid requirement or the same problem could be solved in some other
existing/non-existing way, efficiently.
thanks

Ideally, I want the module to use the variable just as any other symbol.
For example instead of the call to my_kernel_get(), I want to just use
the
variable "myvar" as:
myvar = 10;
This is only possible if the module which defines the variables can
change
the symbol table dynamically, which doesn't sound easily do-able to me.
But, still any insight, thoughts on that would help greatly too.
