# Fuzz -- A kernel fuzzer from Plan 9 space ## Dependencies fuzz(1) is tested on the [9front](http://9front.org) operating system and as such uses its libraries and runs against its kernels. Theoretically fuzz could be ported to unix using [plan9port](https://github.com/9fans/plan9port), but this would require a Plan 9 kernel in user space which doesn't really exist outside of [9vx](https://swtch.com/9vx/) which is untested in this regard. ## Building mk ## Installing mk install ## Usage To perform up to round 5 of fuzzing for the read, write, open, and close calls: fuzz -n 5 read write open close ## Recommended reading - http://doc.cat-v.org/plan_9/4th_edition/papers/comp - http://doc.cat-v.org/plan_9/programming/c_programming_in_plan_9 - https://lsub.org/who/nemo/9.pdf - http://9.postnix.us/hist/3e/plan9_3e_kernel.tgz - http://doc.cat-v.org/plan_9/misc/adding_a_syscall_to_plan_9/plan9_syscall_howto.pdf - http://aiju.de/plan_9/plan9-syscalls - http://man.cat-v.org/9front/2/intro - http://man.cat-v.org/9front/1/syscall - http://mirror.postnix.us/plan9front/sys/src/cmd/syscall/ - http://mirror.postnix.us/plan9front/sys/src/libc/9syscall/ - http://lsub.org/who/nemo/9.intro.pdf - http://fxr.watson.org/fxr/source/?v=PLAN9
