v1 was posted here: https://www.redhat.com/archives/libguestfs/2019-September/thread.html#00337 v2: - Drop the first patch. - Hopefully fix the multiple issues with fork-safety and general behaviour on error paths. Note this requires execvpe for which there seems to be no equivalent on FreeBSD, except some kind of tedious path parsing (but can we assign to environ?) Rich.

This adds a new nbdkit_shutdown() API whereby plugins and filters can request that the server shuts down (asynchronously) during the serving phase. Two new filters are added, one of which depends on this feature and the other not needing it but being somewhat related. Rich.

This works. I'm in the middle of testing whether there is any noticable benefit. Rich.

This is a series of patches to libnbd and nbdkit adding AF_VSOCK support. On the host side it allows you to start an nbdkit instance which listens on a virtio-vsock socket: $ ./nbdkit -fv --vsock memory 1G ... nbdkit: debug: bound to vsock 2:10809 On the guest side you can then use libnbd to connect to the server: $ ./run nbdsh -c 'h.connect_vsock(2, 10809)' -c

The patches following do indeed allow you to compile nbdkit.exe, but it does not actually work yet. I'm posting this experimental series more as a work in progress and to get feedback. Note this does not require Windows itself to build or test. You can cross-compile it using mingw64-* packages on Fedora or Debian, and test it [spoiler alert: it fails] using Wine. Rich.

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw-nolib After a lot of work I have made the port to Windows work without using a separate library. Instead, on Windows only, we build an "import library" (library of stubs) which resolves references to nbdkit_* functions in the main program and fixes up the plugin, basically the first technique outlined in

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw This is the port to Windows using native Windows APIs (not MSYS or Cygwin). This patch series is at the point where it basically now works. I can run the server with the memory plugin, and access it remotely using guestfish, creating filesystems and so on without any apparent problems. Nevertheless there are many
