[libvirt] [PATCH 0/1] Rewrite virt-host-validate in Go & Go packaging complication
by Daniel P. Berrangé 03 Sep '19

03 Sep '19

This series contains code I mostly wrote some 6 months ago as an experiment. I've tidied it up and attempted to integrate it into the libvirt build system. Overall I much prefer the new impl of virt-host-validate, as explained in the commit message, I've wanted todo it this way for a long time, but was put off by C's XML handling verbosity. The main problem I've hit in integrating this work is the RPM build process integration. When building interactively, Go will dynamically download the 3rd party deps from git, similar to how we dynamically pull down gnulib. The difference is that this must happen for end users using tarballs too, not just devs usingn git. We could bundle the deps with our tarball the same way we do with gnulib, but Fedora would not accept using this, as it wants unbundled Go deps. I've done some things in the spec which makes this work against unbundled sources, but this still fails in mock as we don't get the build-id set in the resulting binary. I have attempted to fix that by passing extra flags to go build, but it still fails, so I've got some bug there. The resulting spec rules are very very very unpleasant, having to hardcode a bunch of build flags we should never touch. I've spoken with Nichlos Mailhot who is the Fedora Go packaging expert, who has basically confirmed my experiance that there is no nice solution to what I'm trying todo with the build process. He strongly recommends that we do *not* try to integrate Go into our existing build process, and that we instead keep any Go code as a completely seperate git repo that we build & install separately. This would make the RPM packaging much much simpler to deal with. Given what I've tried here, I'm inclined to agree with his recommendation. In the case of virt-host-validate, this is actually quite a straightforward thing to deal with, as the new impl of virt-host-validate has no direct dep wrt existing lkibvirt code in either direction. So we can trivially put it in a separate git repo. We would merely need an RPM dep from libvirt.spec.in to make the sure the external project gets pulled in on install of libvirt-daemon. Thus this patch is *NOT* something I'm proposing to merge as is. The code itself is fine, but it will need to go into a new git repo of its own. Daniel P.

[libvirt] [PATCH] docs: rewrite hvsupport.html page generator in python
by Daniel P. Berrangé 03 Sep '19

03 Sep '19

As part of an goal to eliminate Perl from libvirt build tools, rewrite the hvsupport.pl tool in Python. This was a straight conversion, manually going line-by-line to change the syntax from Perl to Python. Thus the overall structure of the file and approach is the same. The new impl generates byte-for-byte identical output to the old impl. Signed-off-by: Daniel P.

[libvirt] [PATCH for 5.7.0 0/2] virsh: Rename --precopy-bandwidth migration option
by Jiri Denemark 02 Sep '19

02 Sep '19

The (pre-copy) bandwidth was historically the only bandwidth we supported and thus it is called just "bandwidth" in all other places. E.g., virsh migrate-setspeed or in the migration typed parameter name. Let's make the new option for virsh migrate consistent.

[libvirt] [PATCH] qemu: domain: Fix potential NULL deref when parsing job private data
by Peter Krempa 02 Sep '19

02 Sep '19

A specially crafted XML which would reference a non-existing disk but request the mirror to be registered with the blockjob could potentially make the parser dereference NULL. Fix it by moving the code slightly and just treat it as a wrong job XML. Found by Coverity.

[libvirt] [PATCH] util: Set backing file name for LOOP_GET_STATUS64 queries.
by jcfaracco＠gmail.com 02 Sep '19

02 Sep '19

From: Julio Faracco <jcfaracco(a)gmail.com> This is an issue for LXC loop devices when you are trying to get loop devices info using `ioctl`. Modern apps uses `/sys/dev/block` to grab information about devices, but if you use the method mention you won't be able to retrive the associated file with that loop device. See example below from cryptsetup sources: static char *_ioctl_backing_file(const char *loop) { struct loop_info64 lo64 = {0}; int loop_fd; loop_fd = open(loop, O_RDONLY); if (loop_fd < 0) return NULL; if (ioctl(loop_fd, LOOP_GET_STATUS64, &lo64) < 0) { close(loop_fd); return NULL; } lo64.lo_file_name[LO_NAME_SIZE-2] = '*'; lo64.lo_file_name[LO_NAME_SIZE-1] = 0; close(loop_fd); return strdup((char*)lo64.lo_file_name); } It will return an empty string because lo_file_name was not set.

[libvirt] [RFC] On present using dummy hostdev usb device
by Nikolay Shirokovskiy 02 Sep '19

02 Sep '19

Hi, all! We use an interesting approach when starting/migrating/etc domain with usb hostdev with startupPolicy=optional. We add qemu usb-host device with missing hostaddr/hostbus parameters (dummy device). I guess there are 2 reasons why we do it. First without dummy device migration will fail as described in [1]. Second is an interesting property of dummy device that qemu starts to monitor for attaching of usb devices and binds the first attached to node to the dummy device. So one can start a domain with missing hostdev and attach it later or migrate a domain then detach hostdev on source and attach it on destination. But as qemu binds the first attached device this is not reliable, to say the least. And after all this does not work if domain uses distinct mount namespace which is default. So I question does it make sense to use dummy device at all? In case of migration/resume from suspend/revert to snapshot we can either fix qemu to ignore incoming missing hostdev data or add dummy device temporarily. The latter solution is worse as it brings dummy device behaviour even for a short period of time. However having a temporary dummy device is neccessary step towards the time when all supported versions of qemu do the mentioned ignoring. As to handling attaching of missing hostdev device to node it should be done in libvirt which can do necessary mount namespace actions. (Actually I developing such patches right now but some peculiarities of dummy device bring me here). Nikolay [1] https://www.redhat.com/archives/libvir-list/2012-October/msg00440.html
