-- [Futag] ERROR on target  PQputnbytes2

-- [Futag] Result of compiling: 0 fuzz-driver(s)

При генерации целей их получается 590, при компиляции в виде libFuzzer их выходит >600, а для AFL++ - 0.

[thientc]

если вы собираете Futag на своем компе, проблема будет?

[CourteousSleet]

При окончании сборки получаю такое сообщение:

[thientc]

Необходимо собирать AFLplusplus на вашем компе чтобы все сработало.
можете проверить докер здесь https://github.com/thientc/Futag-tests/tree/main/libpq-standalone.
Если проблема не устранится откройте эту проблему еще раз.

По поводу собирать AFL++ - не актуально, так как проблема в сборке LLVM из FUTAG. В докере всё работает:

afl-fuzz++4.02c based on afl by Michal Zalewski and a large online community
[+] afl++ is maintained by Marc "van Hauser" Heuse, Heiko "hexcoder" Eißfeldt, Andrea Fioraldi and Dominik Maier
[+] afl++ is open source, get it at https://github.com/AFLplusplus/AFLplusplus
[+] NOTE: This is v3.x which changes defaults and behaviours - see README.md
[+] No -M/-S set, autoconfiguring for "-S default"
[*] Getting to work...
[+] Using exponential power schedule (FAST)
[+] Enabled testcache with 50 MB
[+] Generating fuzz data with a length of min=1 max=1048576
[*] Checking core_pattern...
[*] Checking CPU scaling governor...
[+] You have 12 CPU cores and 2 runnable tasks (utilization: 17%).
[+] Try parallel jobs - see docs/parallel_fuzzing.md.
[*] Setting up output directories...
[+] Output directory exists but deemed OK to reuse.
[*] Deleting old session data...
[+] Output dir cleanup successful.
[*] Checking CPU core loadout...
[+] Found a free CPU core, try binding to #0.
[*] Scanning 'input/'...
[+] Loaded a total of 1 seeds.
[*] Creating hard links for all input files...
[*] Validating target binary...
[+] Persistent mode binary detected.
[+] Deferred forkserver binary detected.
[*] Spinning up the fork server...
[+] All right - fork server is up.
[*] Using SHARED MEMORY FUZZING feature.
[*] Target map size: 12
[*] No auto-generated dictionary tokens to reuse.
[*] Attempting dry run with 'id:000000,time:0,execs:0,orig:1'...
    len = 10, map size = 4, exec speed = 92 us
[+] All test cases processed.
[+] Here are some useful stats:

    Test case count : 1 favored, 0 variable, 0 ignored, 1 total
       Bitmap range : 4 to 4 bits (average: 4.00 bits)
        Exec timing : 92 to 92 us (average: 92 us)

[*] No -t option specified, so I'll use an exec timeout of 20 ms.
[+] All set and ready to roll!
