Hi, I would like to propose that we introduce a mechanism in IR to allow arbitrary data to be stashed before a function body. The purpose of this would be to allow additional data about a function to be looked up via a function pointer. Two use cases come to mind: 1) We'd like to be able to use UBSan to check that the type of the function pointer of an indirect function call matches the

This is an alternative approach to https://listman.redhat.com/archives/libguestfs/2023-January/030535.html After discussing this with Dan Berrange we came to the conclusion that you really might want to set LISTEN_FDNAMES to arbitrary short strings (or not set it). Especially when talking to qemu-storage-daemon which would allow you to use these names on the command line. Rich.

Hi, as a followup for the signature fix for mount_vfs [1], here it is a patch series to generate automatically most of the OCaml interfaces of daemon actions. Only the Lvm and Mount modules are left with hand-written interfaces.

This patch is just for discussion. There are still a couple of issues that I'm trying to fix. One is that all of the test guests I have, even ones with static IPs, have multiple interfaces, some using DHCP, so the conditions for adding the Powershell script don't kick in. This makes testing very awkward. However a bigger issue is that I think the premise is wrong. In some registries

v1 was here with much discussion: https://www.redhat.com/archives/libguestfs/2018-December/msg00048.html v2: - Fix the case where there are multiple interfaces. Note this does not preserve order correctly (see patch for comment on why that is a hard problem). - Preserve name servers. This patch is still for discussion only. I'd like to see what might be done to get this upstream

This adds coalescing of adjacent extents of the same type, as mentioned by Eric Blake in the commit message here: https://github.com/libguestfs/libnbd/commit/46072f6611f80245846a445766da071e457b00cd The patch series is rather long because it detours through adding the <vector.h> library from nbdkit into libnbd and replacing ad hoc uses of realloc, char ** etc in various places. Rich.
