Hi,

I would like to test out Nezha on the WolfSSL and mbedTLS libraries. Could you share out the below files, please? Thanks!

build_wolfssl_lf.sh build_mbedtls_lf.sh

Hi,

I cloned nezha-0.1 and run the ./utils/build_helpers/setup.sh but the setup was terminated when I received an error message "FAILED" during the Installation of LibFuzzer.

I opened the README.txt in the directory /nezha-0.1/examples/src/libs/libFuzzer/ and it says "libFuzzer was moved to compiler-rt in https://reviews.llvm.org/D36908"

Did you encounter the same issue? thanks!

When I try to follow the tutorial by running mkdir -p out && ./a.out -diff_mode=1 -artifact_prefix=out/ I get the following error:

INFO: Seed: 3228985162
a.out: ./FuzzerTracePC.cpp:52: void fuzzer::TracePC::InitializeDiffCallbacks(fuzzer::ExternalFunctions *): Assertion `EF->__sanitizer_update_counter_bitset_and_clear_counters' failed.

In the file "/examples/bugs/boringssl-f0451ca3/README.md", the 27th line says "cmd:./test_boringssl ..." and the 43rd line says "cmd:./test_libressl ...". The "./test_boringssl ..." and "./test_libressl ..." were run in the directory "sslcert" but the bash said "./test_boringssl: No such file or directory" and "./test_libressl: No such file or directory".
Do the "./test_boringssl" and "./test_libressl"point to "./test_boringssl.pem.dbg" or "./test_boringssl.der.dbg" or "./test_libressl.pem.dbg" or "./test_libressl.der.dbg" which are generated after executing "./make_all_tests.sh"? If not, how to generate them?

In the same file, the same line says "...18010_0_18010_..." and the 36th line says "openssl: 18010". Does the "18010" in the 36th line refer to the first "...18010_..." or the second "...0_18010..." in the 27th line?

In the same file, the 51st line says "libressl: 1 (ok)". Is the number "1" the return value of LibreSSL? If yes, why "18010_0_18010" instead of "18010_1_1801" in the 27th line?

On the contrary, the 57th line of the file "examples/bugs/libressl-2.4.0/README.md" says "openssl: 1 (ok) and the 48th line ("1_libressl_9010_0689e3080ef6eedb9fee46e0bf9ed8fe__MIN") starts with "1".

In the 48th line of the file "examples/bugs/libressl-2.4.0/README.md", "1_libressl_9010_0689e3080ef6eedb9fee46e0bf9ed8fe__MIN" does not have the same format as in the 27th line of "/examples/bugs/boringssl-f0451ca3/README.md", i.e., "1_libressl_9010" vs "18010_1_1801".

(This problem has been deleted since it was solved.)

In the file "/examples/bugs/boringssl-f0451ca3/README.md", the "stdout" (from the 32nd line to the 35th line) is the output of "./test_openssl.der.dbg" instead of "./test_boringssl.der.dbg". The 36th line, i.e., "openssl: 18010" is not output by the "./test_boringssl.der.dbg". Similarly, the 51st line is not output by "./test_libressl.der.dbg".

In the file "examples/bugs/libressl-2.4.0/README.md", the 57th line is not output by the "./test_openssl.der.dbg"; the 69th line is not output but the "[LSSL] [cert:0x62000000f080 sz:3494] ret=0 depth=2 err=13" is got; the 70th and 71st line are not output by "./test_openssl.der.dbg".

Thanks a lot!
