[Libguestfs] [PATCH nbdkit v2 0/2] Be careful not to leak server heap memory to the client.

Version 1 was here: https://www.redhat.com/archives/libguestfs/2019-April/msg00144.html Version 2 makes a couple of much larger changes: The OCaml patch changes the API of the pread method so it matches what other language bindings are already doing, ie. get the language plugin to return a newly allocated buffer, check it is long enough, copy out the data. The server patch implements a per-thread buffer for all pread and pwrite calls which is zeroed whenever it is extended to avoid the heap memory leak. Rich.
