More patches on the way for improving .list_exports signature and adding .export_description, but this is the promised code showing why nbdkit_string_intern is useful. Patch 4 is somewhat RFC: we could either add new API to take the boilerplate from: foo_config(const char *key, const char *value) { if (strcmp (key, "file") == 0) { CLEANUP_FREE char *tmp = nbdkit_realpath (value);

These two commits add new APIs and enhance nbdkit-ip-filter to allow filtering of Unix domain sockets by the client's PID, UID or GID. eg: nbdkit -U sock --filter=ip ... allow=uid:`id -u` deny=all Rich.

v2 was here: https://www.redhat.com/archives/libguestfs/2020-October/msg00019.html v3: * defence -> defense * Use int64_t instead of int. This compiles on Windows. * Add GC wrappers to OCaml bindings. * New FreeBSD patch. * Removed "pid:" example from the ip filter manual, and added a warning beside the pid documentation. Rich.

This is just a simple update to: https://www.redhat.com/archives/libguestfs/2020-October/msg00015.html rebased on top of current nbdkit master because I pushed a few simple refactorings. Rich.

This is a revision of my .default_export work, plus new work on .export_descriptions and a new exportname filter. I think it is now ready to check in. Things I'd still like in 1.22: - the file plugin should implement .list_exports (patch already posted, but it needs rebasing on this series) - the ext2 filter should override .list_exports when in exportname mode - the nbd plugin should be
