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
97
Functions that are reachable but not covered
54
Reachable functions
79
Percentage of reachable functions covered
31.65%
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.

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.

Implementing fuzzers that target the above functions will improve reachability such that it becomes:
Functions statically reachable by fuzzers
1632 / 5972
Cyclomatic complexity statically reachable by fuzzers
8154 / 24731
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 driver synthesis
New fuzzers
The below fuzzers are templates and suggestions for how to target the set of optimal functions above
window-customize.c
Target file: /src/tmux/window-customize.cTarget functions: window_customize_menu
#include "ada_fuzz_header.h"
int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
af_safe_gb_init(data, size);
/* target window_customize_menu */
UNKNOWN_TYPE unknown_0;
structclient* new_var1 = calloc(sizeof(structclient), 1);
UNKNOWN_TYPE unknown_2;
window_customize_menu(unknown_0, new_var1, unknown_2);
af_safe_gb_cleanup();
}
regress_http.c
Target file: /src/libevent/test/regress_http.cTarget functions: http_cancel_test
#include "ada_fuzz_header.h"
int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
af_safe_gb_init(data, size);
/* target http_cancel_test */
UNKNOWN_TYPE unknown_3;
http_cancel_test(unknown_3);
af_safe_gb_cleanup();
}
tty.c
Target file: /src/tmux/tty.cTarget functions: tty_read_callback
#include "ada_fuzz_header.h"
int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
af_safe_gb_init(data, size);
/* target tty_read_callback */
UNKNOWN_TYPE unknown_4;
UNKNOWN_TYPE unknown_5;
UNKNOWN_TYPE unknown_6;
tty_read_callback(unknown_4, unknown_5, unknown_6);
af_safe_gb_cleanup();
}
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

Function call coverage
This section shows a list of 3rd party function calls and their relative coverage information. By static analysis of the target project code, all of the 3rd party function call and their caller information, including the source file and line number that initiate the call are captured. The caller source code file and line number are shown in column 2 while column 1 is the function name of the 3rd party function call. Each occurrent of the 3rd party function call will occuply a separate row. Column 3 of each row indicate if the 3rd party call in the source file line is unreachable. Column 4 lists all fuzzers that have covered that particular system call in that specific location (source file and line)during their dynamic fuzzing.

Sink analyser for CWEs
This section contains multiple tables, each table contains a list of sink functions/methods found in the project for one of the CWE supported by the sink analyser, together with information like which fuzzers statically reach the sink functions/methods and possible call path to that sink functions/methods if it is not statically reached by any fuzzers. Column 1 is the function/method name of the sink functions/methods found in the project. Column 2 lists all fuzzers (or no fuzzers at all) that have covered that particular function method statically. Column 3 shows a list of possible call paths to reach the specific function/method call if none of the fuzzers cover the target function/method calls. Lastly, column 4 shows possible fuzzer blockers that prevent an existing fuzzer from reaching the target sink functions/methods dynamically.
