[nbdkit PATCH v2 0/8] exportname filter
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

[nbdkit PATCH 0/5] Implement .default_export, nbdkit_string_intern
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);

[nbdkit PATCH v3 00/14] exportname filter
It's been several weeks since I posted v2 (I got distracted by improving libnbd to better test things, which in turn surfaced some major memory leak problems in nbdsh that are now fixed). Many of the patches are minor rebases from v2, with the biggest changes being fallout from: - patch 2: rename nbdkit_add_default_export to nbdkit_use_default_export - overall: this missed 1.22, so update

[RFC nbdkit PATCH 0/4] Progress towards .list_exports
This takes Rich's API proposal and starts fleshing it out with enough meat that I was able to test 'nbdkit eval' advertising multiple exports with descriptions paired with 'qemu-nbd --list'.

[PATCH nbdkit 0/2] Temporarily remove .list_exports for nbdkit 1.22
If you're following nbdkit development upstream you'll have seen that we are still making changes to the .list_exports and related APIs. The current .list_exports API upstream is not how it will look finally. The latest set of proposals was here: https://www.redhat.com/archives/libguestfs/2020-August/thread.html#00330 At the same time I'd like to do an nbdkit 1.22 (stable) release.

[RFC nbdkit PATCH] protocol: Alter .list_exports, add .default_export
I'm about to add an 'exportname' filter, and in the process, I noticed a few shortcomings in our API. Time to fix those before the 1.22 release locks our API in stone. First, .list_exports needs to know if it is pre- or post-TLS, as that may affect which names are exported. Next, overloading .list_exports to do both NBD_OPT_LIST and mapping "" to a canonical name is

[PATCH nbdkit v2] PROPOSED: server: Implement list_exports.
Updated proposal, taking into account the default export. Instead of adding a second call, I made a couple of changes to list_exports: (1) If the plugin has a concept of a default export, it should add it as the first element in the exports list. (2) There is a new default_only flag which tells the plugin that the client is trying to request the name of the default export, so the

[nbdkit PATCH 0/2] More language bindings for .list_exports
This picks up python and ocaml. Some of our languages are lacking a number of bindings (for example, lua and perl lack .extents, so I didn't have anything to copy from), and I felt less comfortable with golang and rust. But for python and ocaml, I was able to test a working implementation. Eric Blake (2): python: Implement .list_exports and friends ocaml: Implement .list_exports and

[PATCH nbdkit] New ondemand plugin.
This creates filesystems on demand. A client simply connects with a desired export name and a new export is created. The export is persistent (until deleted by the server admin), and clients may disconnect and reconnect. In some respects this is similar to the nbdkit-tmpdisk-plugin, or nbdkit-file-plugin with the dir= option. --- plugins/ondemand/nbdkit-ondemand-plugin.pod | 190 ++++++

[nbdkit PATCH 0/3] .list_exports in nbd plugin
Another series on top of my exportname filter, marking off another todo bullet point. With this, you can now use the NBD plugin as a transparent passthrough of all export names served by the remote server in both directions (list advertisement server to client, and export name from client to server).

[nbdkit RFC PATCH 4/4] exportname: New filter
Add a new filter to make it easier to add exports to a plugin that does advertise them, to avoid advertising where a plugin's list might be an information leak, and to alter which export name is used in place of "".
