[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.

[PATCH nbdkit 1/2] server: Call .get_ready before redirecting stdin/stdout to /dev/null.
...n + --run was broken because of the following sequence of
events:
(1) After .config_complete, server redirects stdin/stdout to /dev/null.
(2) Server then calls vddk_get_ready which reexecs.
(3) We restart the server from the top, but with stdin/stdout
redirected to /dev/null. So saved_stdin/saved_stdout save
/dev/null.
(4) run_command is called which "restores" /dev/null as stdin/stdout.
(5) The output of the --run option is sent to /dev/null.
In addition to fixing this problem with VDDK, it also makes general
sense not to redirect stdin/stdout before calling .get_ready since
this...
