libFuzzer is Clang's fuzzer, and alternative to using AFL: https://llvm.org/docs/LibFuzzer.html I implemented an alternative method of fuzzing for libnbd earlier today and it's pretty simple: https://github.com/libguestfs/libnbd/commit/c19a6fbae9a21a7d4693418706c59e81ed256875 However it's considerably more difficult to use libFuzzer with non-library code -- in this case nbdkit.

It's

For commands with long names and/or short descriptors, you can end up going over 72 characters in the first line of the man page (causing podwrapper to complain).

Hi all, The blog entry [1] suggest that one of the buildbots constantly fuzzes clang and clang-format. However, the actual bot [2] only tests the fuzzer itself over a well-known set of bugs in standard software (eg. Heartbleed [3] seems to be among them). Has there actually ever been a buildbot that fuzzes clang/LLVM itself? Another (obvious?) fuzzing candidate would be the LLVM's bitcode

Thanks for your comments, Ralph and Jean-Marc. Please find attached the amended patch: - decodes a sequence of input packets rather than just one (I'm planning on using the Opus test vectors as the seed corpus) - decides on decoder setup and FEC independently of the packet data - uses Opus functions to parse ToC Cheers, Felicia On Sun, Jan 29, 2017 at 9:48 PM Jean-Marc Valin <jmvalin at

I have a project I want to do based on Libfuzzer. Is there a separate list for it or should I bring up any ideas for it here? What I have in mind is to fuzz Postgres. Trying to fuzz the SQL interpreter in general is not very productive because traditional fuzzers try to execute the entire program repeatedly and it has a fairly high startup and shutdown cost. Also the instrumentation-guided

HI think I have a fairly nicely integrated Libfuzzer based fuzzer in Postgres now. I can run things like: SELECT fuzz(100000,'select regexp_matches(''foo/bar/baz'',$1,''g'')') Which makes it convenient to fuzz arbitrary public functions available in SQL. (I haven't figured out what interface to make for fuzzing internal functions which take char

At the moment it is empty, so probably it does not exist. Remove it to avoid adding spurious content to the pkg-config file in case that variable will get a value in the future. --- lib/libnbd.pc.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/libnbd.pc.in b/lib/libnbd.pc.in index ba91f49..294c090 100644 --- a/lib/libnbd.pc.in +++ b/lib/libnbd.pc.in @@ -8,4 +8,4 @@

Hi all, While playing with libFuzzer, it's a little cumbersome to having to copy the buffer just in order to null-terminate it. Is a null-terminated buffer an often-enough usage scenario to warrant a libFuzzer commandline configuration switch to always generate a null-terminated test case?

I'm pleased to announce the releases of libnbd 1.2 and nbdkit 1.16. These are a high performance Network Block Device (NBD) client library and server. Key features of libnbd: * Synchronous API for ease of use. * Asynchronous API for writing non-blocking, multithreaded clients. You can mix both APIs freely. * High performance. * Minimal dependencies for the basic library. *
