Dear All, I am posting again the same problem that is "Netlink socket creation returns NULL" when I try to create it in handle_ept_violation() in the vmx.c file. Actually, I am trying to use netlink to send information (i.e., guest physical address) from kernel space to user space. The netlink socket creation is not working in the context of vmx.c, but it works perfectly when I test my code in a kernel module and load it. Code is in the attachement. I have tested many things such as shared memory, kernel thread, sleep function, etc. but nothing worked out. Can you please what's the problem?
*What's the best too/way that can provide full duplex (two-way) communication between kernel and user spaces in any context (from any kernel source file)*. Thank you. -- *Best Regards,* *Mr. Irfan Ullah* PhD Candidate Data and Knowledge Engineering(DKE) Lab Department of Computer Science and Engineering Kyung Hee University, South Korea. +82-010-591-51651 <+82%2010-3877-8867> sahibzada...@gmail.com sahibzada_irfanullah
