## Prereqs
See [AFL docs](https://afl-1.readthedocs.io/en/latest) for installing afl.
On ubuntu this may be enough:
```
sudo apt install afl
```
Install AFL, see [..](..)
You may have to change cpu frequency:
```
cd /sys/devices/system/cpu
echo performance | tee cpu?/cpufreq/scaling_governor
```
And possibly change core behaviour:
```
echo core >/proc/sys/kernel/core_pattern
```
Build and install a clixon system (in particular the backend, the CLI will be replaced)
## Build
Build clixon statically with the afl-clang compiler:
Build clixon cli statically with the afl-clang compiler:
```
CC=/usr/bin/afl-clang-fast LINKAGE=static ./configure
CC=/usr/bin/afl-clang-fast LINKAGE=static ./configure # Dont care about restconf
make clean
cd apps/cli
make clixon_cli

After (or during) the test, investigate results in the output dir.
