Subject: fuzz: add a LLVMFuzzerInitialize() to all fuzzers
X-Git-Tag: tevent-0.11.0~1520
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e0dd4d0ac02c7040e8f6d346d4a8b7d087adfc04;p=thirdparty%2Fsamba.git

fuzz: add a LLVMFuzzerInitialize() to all fuzzers

To compile the AFL binaries, we need every fuzzer to have a consistent
set of functions. Some fuzzers require the initialize function, so all
the rest must have an empty one.

AFL binaires are handy for testing the fuzz results in a less magical
environment than libfuzzer/honggfuzz give you.
