[PATCH nbdkit v2 0/2] Implement fuzzing using Clang's libFuzzer.
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-November/msg00003.html
This version depends on:
https://www.redhat.com/archives/libguestfs/2019-November/msg00004.html
and this series:
https://www.redhat.com/archives/libguestfs/2019-November/msg00009.html
The delta has been reduced slightly because of changes made possible
by cleaning up and fixing the quit path in nbdkit. It's

[PATCH nbdkit 0/2] Implement fuzzing using Clang's libFuzzer.
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.

Re: Fuzzing Questions
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 get the following error:

[nbdkit PATCH 0/4] More work with retry safety
I'm still working on another set of patches to have reopen call
.finalize/.prepare (so that another filter can safely appear between
retry and the plugin), but for tonight, these are the patches I think
are ready to go.
Eric Blake (4):
retry: Handle can_fua and can_fast_zero changes
tests: Test retry with different fua/fast-zero flags
server: Close backends if a filter's .open fails
