Project overview
High level conclusions
Fuzzers reach 17.25% of all functions. Improvements need to be made
Fuzzers reach 16.72% of cyclomatic complexity. Improvements could be made
Fuzzer theme-load-fuzz is blocked: runtime coverage only covers 0.0% of its reachable functions.
Fuzzer server-fuzz is blocked: runtime coverage only covers 0.0% of its reachable functions.
Fuzzer irssi-fuzz is blocked: runtime coverage only covers 0.0% of its reachable functions.
Fuzzer event-get-params-fuzz is blocked: runtime coverage only covers 0.0% of its reachable functions.

Project functions overview
The following table shows data about each function in the project. The functions included in this table corresponds to all functions that exist in the executables of the fuzzers. As such, there may be functions that are from third-party libraries.
For further technical details on the meaning of columns in the below table, please see the Glossary .
| Func name | Functions filename | Args | Function call depth | Reached by Fuzzers | Fuzzers runtime hit | Func lines hit % | I Count | BB Count | Cyclomatic complexity | Functions reached | Reached by functions | Accumulated cyclomatic complexity | Undiscovered complexity |

Call tree overview
The following is the call tree with color coding for which functions are hit/not hit. This info is based on the coverage achieved of all fuzzers together and not just this specific fuzzer. This should change in the future to be per-fuzzer-basis.
For further technical details on what the call tree overview is, please see the Glossary .
Full calltree
The following link provides a visualisation of the full calltree overlayed with coverage information: full calltree
For futher technical details on how the call tree is made, please see the Glossary .
Fuzz blockers
The followings nodes represent call sites where fuzz blockers occur

Functions hit (dynamic analysis based)
Covered functions
0
Functions that are reachable but not covered
577
Reachable functions
577
Percentage of reachable functions covered
0.0%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.

The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.

Remaining optimal interesting functions
The following table shows a list of functions that are optimal targets. Optimal targets are identified by finding the functions that in combination reaches a high amount of code coverage.

Implementing fuzzers that target the above functions will improve reachability such that it becomes:
Functions statically reachable by fuzzers
3005/4330
Cyclomatic complexity statically reachable by fuzzers
22843 / 29034
All functions overview
The status of all functions in the project will be as follows if you implement fuzzers for these functions
| Func name | Functions filename | Args | Function call depth | Reached by Fuzzers | Fuzzers runtime hit | Func lines hit % | I Count | BB Count | Cyclomatic complexity | Functions reached | Reached by functions | Accumulated cyclomatic complexity | Undiscovered complexity |
