This is what I've been playing with in response to my earlier question about what to do with 'nbdkit -s sh -' (https://www.redhat.com/archives/libguestfs/2020-April/msg00032.html) I'm still open to ideas on a better name, and/or whether adding <stdbool.h> to our public include files is a good idea (if not, returning int instead of bool is tolerable).

In v2: - use int instead of bool in the public header - split the tests from the code - don't overload test-layers; instead, add new tests - add a missing fflush exposed by the new tests - other minor cleanups Eric Blake (3): server: Add nbdkit_stdio_safe server: Sanitize stdin/out before running plugin code server: More tests of stdin/out handling docs/nbdkit-plugin.pod |

Thinking about Sasha's patches, we can reduce ring usage for virtio net small packets dramatically if we put virtio net header inline with the data. This can be done for free in case guest net stack allocated extra head room for the packet, and I don't see why would this have any downsides. Even though with my recent patches qemu no longer requires header to be the first s/g element, we
