# Clixon fuzzing
|
|
|
|
This dir contains code for fuzzing clixon cli.
|
|
|
|
Note: cli plugins do not work.
|
|
|
|
## Prereqs
|
|
|
|
See [AFL docs](https://afl-1.readthedocs.io/en/latest) for installing afl.
|
|
On ubuntu this may be enough:
|
|
```
|
|
sudo apt install afl
|
|
```
|
|
|
|
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
|
|
|
|
Build clixon statically with the afl-clang compiler:
|
|
```
|
|
CC=/usr/bin/afl-clang-fast LINKAGE=static ./configure
|
|
make clean
|
|
cd apps/cli
|
|
make clixon_cli
|
|
sudo make install
|
|
```
|
|
|
|
## Run tests
|
|
|
|
Start the backend and Use the script `runfuzz.sh` to run one test with a cli spec and an input string, eg:
|
|
```
|
|
./runfuzz.sh /usr/local/etc/hello.xml "set table parameter a value 23"
|
|
```
|
|
|
|
After (or during) the test, investigate results in the output dir.
