Re: Kernel Module with multiple source files not initializing

[Irfan Ullah (울라 이르판) <irfan@xxxxxxxxxxxxx>]

Thanks you. 

Yes, I have tested it. " smod | grep your_module_name" command shows that the module is loaded but the "dmesg" shows nothing. 

Following is the output of the commands.

ssd@ssd:~/Desktop/Kernel_User_comm$ lsmod | grep netlink_kernel_module

netlink_kernel_module    16384  0

ssd@ssd:~/Desktop/Kernel_User_comm$ dmesg
ssd@ssd:~/Desktop/Kernel_User_comm$

Dear All,

I have developed a kernel module consists of one source file that sends and receives  message to the user space.  I have spitted the source code in two files, and now I  am trying to develop kernel module from these source files. After compiling and linking without any problems, I insmod the module but I didn’t see any of the printk() I wrote, in fact, the module can be inserted and removed, but it does nothing. Code is in the attached file zipped file.

I tried many things , e.g.,  link1, link2, and link3 etc.  but nothings worked out. 

I also used nm to inspect the module, but, as expected, there was no signs of "__init and __exit" functions can in the output. 

I assume you have verified that your module is loaded by something like

lsmod | grep your_module_name

and log level allows KERN_ALERT printing.
