Project overview: capnproto

High level conclusions

Reachability and coverage overview

Functions statically reachable by fuzzers
2.0%
258 / 13319
Cyclomatic complexity statically reachable by fuzzers
2.0%
1055 / 68755
Runtime code coverage of functions
42.0%
5588 / 13319

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 .

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

Runtime coverage analysis

Covered functions
1726
Functions that are reachable but not covered
105
Reachable functions
526
Percentage of reachable functions covered
80.04%
NB: The sum of covered functions and functions that are reachable but not covered need not be equal to 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 of our static analysis capabilities.
Warning: The number of covered functions are larger than the number of reachable functions. This means that there are more functions covered at runtime than are extracted using static analysis. This is likely a result of the static analysis component failing to extract the right call graph or the coverage runtime being compiled with sanitizers in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Analyses and suggestions

Optimal target analysis

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, yield a high code coverage.

Func name Functions filename Arg count Args Function depth hitcount instr count bb count cyclomatic complexity Reachable functions Incoming references total cyclomatic complexity Unreached complexity
capnp::_::checkDynamicTestMessage(capnp::DynamicStruct::Builder) /src/capnproto/c++/src/capnp/test-util.c++ 1 ['N/A'] 63 0 14 3 2 4776 0 13530 12515

Implementing fuzzers that target the above functions will improve reachability such that it becomes:

Functions statically reachable by fuzzers
19.0%
2524 / 13319
Cyclomatic complexity statically reachable by fuzzers
20.0%
13560 / 68755

All functions overview

If you implement fuzzers for these functions, the status of all functions in the project will be:

Func name Functions filename Args Function call depth Reached by Fuzzers Runtime reached by Fuzzers Combined 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

Fuzz engine guidance

This sections provides heuristics that can be used as input to a fuzz engine when running a given fuzz target. The current focus is on providing input that is usable by libFuzzer.

/src/capnproto/c++/src/capnp/llvm-fuzzer-testcase.c++

Dictionary

Use this with the libFuzzer -dict=DICT.file flag


Fuzzer function priority

Use one of these functions as input to libfuzzer with flag: -focus_function name 

-focus_function=['void kj::_::Debug::log&, char const (&) [4], capnp::Text::Reader>(char const*, int, kj::LogSeverity, char const*, char const (&) [90], kj::_::DebugComparison&, char const (&) [4], capnp::Text::Reader&&)', 'capnp::schema::Value::Which capnp::_::StructReader::getDataField(unsigned int) const', 'kj::Own::~Own()', 'kj::String kj::_::operator*(kj::_::Stringifier, kj::_::DebugComparison&)', 'kj::ArrayDisposer::Dispose_::destruct(void*)', 'kj::ArrayBuilder::finish()', 'capnp::schema::Type::Which capnp::_::StructReader::getDataField(unsigned int) const', 'kj::String kj::_::concat, kj::FixedArray, kj::CappedArray >(kj::CappedArray&&, kj::FixedArray&&, kj::CappedArray&&)', 'kj::Maybe::Maybe(kj::None)', 'capnp::schema::Type::AnyPointer::Unconstrained::Which capnp::_::StructReader::getDataField(unsigned int) const']

Runtime coverage analysis

This section shows analysis of runtime coverage data.

For futher technical details on how this section is generated, please see the Glossary .

Files and Directories in report

This section shows which files and directories are considered in this report. The main reason for showing this is fuzz introspector may include more code in the reasoning than is desired. This section helps identify if too many files/directories are included, e.g. third party code, which may be irrelevant for the threat model. In the event too much is included, fuzz introspector supports a configuration file that can exclude data from the report. See the following link for more information on how to create a config file: link
