[libvirt] [PATCH for 4.6.0] tests: qemucapsprobe: Fix output after swithching to jansson
by Peter Krempa 01 Aug '18

01 Aug '18

Jansson does not put a newline at the end of formatted JSON strings. This breaks the qemucapsprobe utility as we need to keep the spacing so that tests work. Add an explicit newline.

[libvirt] [jenkins-ci PATCH] lcitool: Update OS when building Docker images
by Andrea Bolognani 01 Aug '18

01 Aug '18

The last build of the Fedora Rawhide Docker image failed with Transaction check error: file /usr/lib64/libgdbm_compat.so.4.0.0 from install of gdbm-libs-1:1.16-1.fc29.x86_64 conflicts with file from package gdbm-1:1.14.1-3.fc28.x86_64 caused by the gdbm package having recently been split. Especially with fast-moving distribution such as Fedora Rawhide and Debian Sid, we can't rely on the base OS not changing over time, so merely installing the packages we need on top of that is not enough. Additionally, updating the OS brings the Docker images closer to the guests running on CentOS CI, which are updated daily.

[libvirt] [dbus PATCH] Install daemon under @sbindir@
by Andrea Bolognani 01 Aug '18

The libvirt-dbus daemon is not supposed to be invoked explicitly by the user, but rather to be spawned on-demand by the D-Bus daemon: as such, @sbindir@ is a more suitable location in which to install it.

[libvirt] [PATCH] util: avoid symbol clash between json libraries
by Daniel P. Berrangé 01 Aug '18

01 Aug '18

The jansson and json-glib libraries both export symbols with a json_ name prefix and json_object_iter_next() clashes between them. Unfortunately json_glib is linked in by GTK, so any app using GTK and libvirt will get a clash, resulting in SEGV. This also affects the NSS module provided by libvirt Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL flag which allows us to hide the symbols from the application that loads libvirt or the NSS module. Some preprocessor black magic and wrapper functions are used to redirect calls into the dlopen resolved symbols. Signed-off-by: Daniel P.

[libvirt] [PATCH v2 RESEND 00/12] PCI passthrough support on s390
by Yi Min Zhao 01 Aug '18

01 Aug '18

Abstract ======== The PCI representation in QEMU has recently been extended for S390 allowing configuration of zPCI attributes like uid (user-defined identifier) and fid (PCI function identifier). The details can be found here: https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg07262.html To support the new zPCI feature of the S390 platform, two new XML attributes, @uid and @fid, are introduced for device addresses of type 'pci', i.e.: <hostdev mode='subsystem' type='pci'> <driver name='vfio'/> <source> <address domain='0x0001' bus='0x00' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0' uid='0x0003' fid='0x00000027'/> </hostdev> uid and fid are optional attributes. If they are defined by the user, unique values within the guest domain must be used. If they are not specified and the architecture requires them, they are automatically generated with non-conflicting values. Current implementation is the most seamless one for the user as it unites the address specific data of a PCI device on one XML element. It could accommodate both specifying our special parameters (uid and fid) and re-using standard statements (domain, bus, slot and function) for PCI devices. User can still specify bus/slot/function for the virtualized PCI devices in the XML. Thus uid/fid act as an extension to the PCI address and are stored in a new structure 'virZPCIDeviceAddress' which is a member of common PCI Address structure. Additionally, two hashtables are used for assignment and reservation of uid/fid. In support of extending the PCI address, a new PCI address extension flag is introduced. This extension flag allows is not only dedicated for the S390 platform but also other architectures needing certain extensions to PCI address space. Code Base ========= commit in master: 767f9e1449b1a36111532847f0c62dc758263c42 qemu: validate: Enforce compile time switch type checking for videos Change Log ========== v1->v2: 1.

[libvirt] [PATCH v2] util: avoid symbol clash between json libraries
by Daniel P. Berrangé 31 Jul '18

31 Jul '18

The jansson and json-glib libraries both export symbols with a json_ name prefix and json_object_iter_next() clashes between them. Unfortunately json_glib is linked in by GTK, so any app using GTK and libvirt will get a clash, resulting in SEGV. This also affects the NSS module provided by libvirt Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL flag which allows us to hide the symbols from the application that loads libvirt or the NSS module. Some preprocessor black magic and wrapper functions are used to redirect calls into the dlopen resolved symbols. Signed-off-by: Daniel P.

[libvirt] [PATCH 00/11] Add checks to ensure a name isn't all whitespace
by John Ferlan 31 Jul '18

31 Jul '18

https://bugzilla.redhat.com/show_bug.cgi?id=1107420 As unusual as the case may be, having a name of all white space has been allowed. This leads to the obvious problem of how a future usage would be able to "utilize" that resource since it's not "simple" to determine what combination of spaces and tabs are being used for the name. So add code to various drivers in order to inhibit this for those resources that would consider using a name for some sort of lookup type reference. For a majority of drivers, the schema validation also allowed the name; however, a couple (secrets and nwfilters) the virt-xml-validate would fail. Still this wouldn't necessarily stop someone - just slow them down. So for those the test xml file must use the *-invalid.xml type syntax to inhibit virschematest from looking at the schema. Similar validation for node devices and interfaces is not necessary since those are referencing system named elements which wouldn't have the oddly named resource. Also, while it could be checked, avoid the check for Storage Volumes as there's no way to "inhibit" in the parse logic algorithm. This is not for 4.6.0, but figured I'd get it on list for consideration for 4.7.0. Yes, it's quite unusual and one has to wonder who thinks up this type of situation, but still in the long run we should attempt to avoid it anyway. I've only added the extra checking for qemu and lxc domains, leaving others to those maintainers to choose to utilize.
