similar to: Dynamically-Linked MIPS binary to LLVM IR

Hi all, I'm not sure if this is the place I should ask this question, but as it is related to LLVM I'll post it. Is it possible to take an arbitrary MIPS ELF binary which is dynamically-linked and generate it's LLVM-IR in order to either execute it in an x86_64 machine or fuzz a function from that binary? This question seems simple but I've had some issues on finding useful

Hi, I wanted to propose another project that is based on LLVM for inclusion on the http://llvm.org/ProjectsWithLLVM/ page. Hope it qualifies and can be included. Below description is copied verbatim from their website. I formatted it to follow the format of entries on aforementioned page: > RetDec > > by Avast > > RetDec is an open-source machine-code decompiler based on LLVM.

Bugs found by oss-fuzz in llvm are now public: https://bugs.chromium.org/p/oss-fuzz/issues/list?q=proj-llvm (and the new ones will be public too). I've also added llvm-bugs at lists.llvm.org to the list of e-mail recipients: https://github.com/google/oss-fuzz/blob/master/projects/llvm/project.yaml On Tue, Aug 29, 2017 at 4:27 PM, Justin Bogner <mail at justinbogner.com> wrote: >

Hi, I need you help. I've been reading and searching on Google for a while know to try to get my gamepad (joystick, whatever) to work. Of course that the gamepad works fine under GNU/linux natives apps, like ZNES. First of all, is not a gamepad or joystick actually, it's an adaptor that lets me connect 2 PSII joysticks in one USB port. The module I'm using is joydev, and I'm

So I installed Libnbd which worked fined and then I was trying to run Libnbd-fuzz-wrapper.c and with afl using : afl-fuzz -i fuzzing/testcase_dir -o fuzzing/sync_dir -M fuzz01 \./fuzzing/libnbd-fuzz-wrapper @@ when I try that command it gives me an error saying Libnbd-fuzz-wrapper.c is not an EFL binary. Then I tried to compile Libnbd-fuzz-wrapper.c first into an executable file and then I

Hi, We have several llvm fuzz targets running on OSS-Fuzz, a continuous automated fuzzing service: https://github.com/google/oss-fuzz https://www.usenix.org/sites/default/files/conference/protected-files/usenixsecurity17_slides_serebryany.pdf It has reported a few bugs in cxa_demangler, clang, and dwarfdump already, and we expect to add more fuzz targets to it soon (llvm-isel-fuzzer,

Hi Mitch, Thank you for the response. 1. You don't need to build the library with `-fsanitize-coverage=...`, using `-fsanitize=fuzzer-no-link,address` should be sufficient. - Acknowledged 2. (although you can actually build object files/shared libraries with -fsanitize=fuzzer, and the libFuzzer main won't be linked, if this makes your build process easier). - with just the *fuzzer

I have a generic function test.equal <- function(obj1, obj2, ...) UseMethod("test.equal") however, the only argument that specific methods use is "fuzz" so I would like to change this to test.equal <- function(obj1, obj2, fuzz=???) UseMethod("test.equal") The problem is that some methods use slightly different default values for fuzz than others. How should

I am working of using libfuzzer and asan to test out a third-party library. As demonstrated in the tutorial, I wrote a fuzz target to fuzz a specific function in the library. The fuzz target is then linked to the library and compiles clean and I do see some tests generated by the fuzzer. However, I have some questions regarding the "right" way to go about doing this. I have doubts that

Hi all, I'm working on fuzzing Opus with OSS-Fuzz and have started with the decoder. Attached is a patch to add the corresponding fuzz target. Please let me know if there are any concerns?

Hi Felicia, Overall the patch looks good to me and it's a pretty reasonable starting points. Some minor comments below.

Hi, Recently I want to fuzz samba systematically (instead of functional fuzzing like OSS-Fuzz/samba). However, the fuzzer acts like smbclient and needs to establish a connection with the samba server via NTLM authentication. The NTLMSSP_Challenge sent by the server is not deterministic, which can render the fuzzing based on previously captured traffic futile. Does samba provide a fuzzing mode
