Remove cargo afl installation

[tokatoka]

If I understand the Dockerfile correctly, smite is not really instrumenting any Rust code. (and neither is it using cargo afl subcommands)

so I think we can delete it from the Dockerfile

fwiw; it was removed from fuzzamoto too

makes sense to me

If I understand the Dockerfile correctly, smite is not really instrumenting any Rust code. (and neither is it using cargo afl subcommands)

It's instrumenting the rust-lighting (LDK) code, that's why it's only used in the LDK Dockerfile. It won't instrument any Smite code. If we remove it, the fuzzer will not get any coverage feedback from LDK workloads.

Here, it compiles rust-lightning with instrumentation.

cargo afl build --release

fwiw; it was removed from fuzzamoto too

I believe they removed it because they only need to instrument the C++/Go code, and they don't need to compile Fuzzamoto with instrumentation.

Here's a bit more context: #2

I see.
I thought this cargo-afl came from the dockerfile of fuzzamoto, but didn't know it was really actually used.
thanks for clarifying this!
