deadman

Simple kernel module to kill your machine if sh*it happened.

Note: This is very hacky. Also my first steps into writing kernel-space code. So please be gentile :)

Stuff it can do:

• ping a host periodically
• watch for unresponsiveness/suspension
• suicide on rmmod

Stuff I wanna fix:

• not use user-land calls to ping to check availability of a host.
• optionally make sure test conditions are met at least once before engaging
• more...

Usage:

make                # You need to `make clean` if you updated you kernel before building
modinfo deadman.ko  # To see what it's like
insmod deadman.ko   # Hope it does not blow up unexpectedly :)

License:

GPLv2. I would use the Apache-2.0 license, but some symbols in the kernel require GPL compliance.
