[libvirt] [PATCH] virSecuritySELinuxTransactionCommit: Don't mask error
by Michal Privoznik 13 Nov '18

13 Nov '18

In 4674fc6afd6 I've implemented transactions for selinux driver. Well, now that I am working in this area I've notice a subtle bug: @ret is initialized to 0 instead of -1. Facepalm.

[libvirt] [PATCH] travis: Switch from Docker Hub to quay.io
by Andrea Bolognani 13 Nov '18

As it's currently impossible for us to create new automated builds on Docker Hub (see [1]), and quay.io doesn't suffer from the same problem while still having all the feature we need, switch to the latter.

[libvirt] [PATCH] util: fix handling of unspecified port in URI
by Daniel P. Berrangé 13 Nov '18

13 Nov '18

When no server name is provided in the URI, modern versions of libxml2 will set the port to '-1'. This is a change from behaviour with earlier versions which set it to 0. Libvirt expects the port to be 0 in these cases and as a result we get a bug when connecting to URIs which lack a server name: $ virsh -c test+ssh:///default list error: failed to connect to the hypervisor error: Cannot recv data: Bad port '-1': Connection reset by peer This libxml2 change was attempting to fix another bug identified by libvirt where it didn't roundtrip URIs correctly in: https://github.com/GNOME/libxml2/commit/beb7281055dbf0ed4d041022a67c6c5cfd1… Essentially libxml2 was not expecting apps to look at the URI port field when the server name is not provided. This was a reasonable assumption, but none the less libvirt did look at it :-) The fix is to ensure we explicitly set port to 0 when server name is not present, avoiding undefined behaviour for the port field in libxml2.

[libvirt] [PATCH v3] lxc: Include support to lxc version 3.0 or higher.
by Julio Faracco 12 Nov '18

12 Nov '18

This patch introduce the new settings for LXC 3.0 or higher. The older versions keep the compatibility to deprecated settings for LXC, but after release 3.0, the compatibility was removed. This commit adds the support to the refactored settings. v1-v2: Michal's suggestions to handle differences between versions. v2-v3: Adding suggestions from Pino and John too.

[libvirt] [PATCH v2] conf: Add new module node_device_util
by Erik Skultety 12 Nov '18

12 Nov '18

There's a lot of stuff going on in src/conf/nodedev_conf which is sometimes not directly related to config and we're not really consistent with putting only parser/formatter related stuff here, e.g. like we do for domains. So, let's start simply by adding a new module node_device_util containing some of the helpers. Unfortunately, even though these helpers tend to open a secondary driver connection and would be much therefore better suited as a nodedev driver module, we can't do that without pulling headers from the driver into conf/ and that's wrong because we want conf/ to stay driver-agnostic.

[libvirt] [PATCH] bt: Mark the bluetooth subsystem as deprecated
by Thomas Huth 12 Nov '18

12 Nov '18

It has been unmaintained since years, and there were only trivial or tree-wide changes to the related files since many years, so the code is likely very bitrotten and broken. For example the following segfaults as soon as as you press a key: qemu-system-x86_64 -usb -device usb-bt-dongle -bt hci -bt device:keyboard Since we are not aware of anybody using bluetooth with the current version of QEMU, let's mark the subsystem as deprecated, with a special request for the users to write to the qemu-devel mailing list in case they still use it (so we could revert the deprecation status in that case).
