Project overview: boringssl
High level conclusions
Reachability and coverage overview
Warning:
The number of runtime covered functions are larger than the
number of reachable functions. This means that Fuzz Introspector found
there are more functions covered at runtime than what is considered
reachable based on the static analysis. This is a limitation in the
analysis as anything covered at runtime is by definition reachable by the
fuzzers.
This is likely due to a limitation in the static analysis. In this case, the
count of functions covered at runtime is the true value, which means this
is what should be considered "achieved" by the fuzzer.
Use the project functions table below to query all functions that were not covered at runtime.
Project functions overview
The following table shows data about each function in the project. The functions included in this table correspond 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
The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree
The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree.

Call tree
The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview
