• src/ - kernel module source files
  • src/module.c - kernel module entry point, netlink communication
  • src/user.c - keeps track of clients actively communicating with the kernel module
  • src/db.c - storage implementation. top-level put/get are implemented here
  • src/io.c - low-level block I/O system, and buffer manager
• client/ - user-space client library
  • client/client.c - client API functions
  • client/conn.c - netlink connection management
  • client/main.c - test program. built to bin/krcl
• include/ - common include files
  • include/kr_common.h - header file used by both client and kernel module
  • include/kr_client.h - client library API header

Note: on Ubuntu, you need the libnl-3-dev package.

1. Run make to build the kernel module and client library (must be on linux)
2. Run sudo insmod bin/krdb.ko to start the module
3. Run sudo rmmod krdb to remove it. (Or restart)
