v1 was here: https://www.redhat.com/archives/libguestfs/2020-February/msg00220.html This patch series is a little bit better. It's still a bit of a hack. The _real_ fix for this is outlined in the TODO file (see patch 1) but that requires a lot more work than we could do before 1.42 is released, unless we delay 1.42 for a lot longer. I'm hoping with this to have something which works

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the

This is a series of simplifications to the stubs code. It's all refactoring, there is no functional change. Rich.

These 3 patches implement support for APIs which must accept a mountable, but don't update apis which must return mountables. Matt

https://bugzilla.redhat.com/show_bug.cgi?id=1477623 The first two patches are cleanups. The third patch changes the way that we handle Device and Dev_or_Path parameters so that a parameter marked as such can really only contain a block device name (and not, for instance, a chardev). Using a chardev here caused hangs in the API. The next two patches fix API usage to conform to this new stricter

Various changes/fixes to use smaller stack frames. Rich.

In the kernel and qemu communities it is routine for patches that will be backported to stable branches to be posted for review. I'm proposing we do the same for libguestfs stable branches. All of the attached have been tested with 'make check-release'. Rich.

This started as a simple warning-elimination change. I'll get back to that series shortly ;-) It turned into a factorization and constification exercise during which I got a taste of ocaml. Thanks to Rich Jones for help with a few snippets in generator.ml. The overall result is that many previously-manually-maintained bits from daemon/*.c functions are now hoisted into the automatically-
