RHBA-2011:0705 - spice-server bug fix and enhancement update

Synopsis

spice-server bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

An updated spice-server package that fixes several bugs and adds a number of enhancements is now available.

Description

The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol designed for virtual environments. SPICE users can access a virtualized desktop or server from the local system or any system with network access to the server. SPICE is used in Red Hat Enterprise Linux for viewing virtualized guests running on the KVM hypervisor or on Red Hat Enterprise Virtualization Hypervisors.

The spice-server package has been rebased to upstream version 0.8, which fixes the following bugs and adds the following enhancements (BZ#672035, BZ#645096):

  • spice-server tried to use migration information even when it was not provided or required. This resulted in a segmentation fault in the client machine (the source of the migration operation). A check now determines whether the client has provided or is required to provide migration information. (BZ#674451)

  • JPEG message encoding was handled differently between client and server, such that the server passed the client a value to determine an image's orientation, which the server interpreted as being invalid. This resulted in the client aborting. The value passed from the server is now the one the client expects, so the client no longer aborts. (BZ#670239)

  • The palette cache was not always synchronized between client and server following live migration of a virtual machine with multiple monitors. The client side palette cache was not cleaned after migration, which caused the client to terminate unexpectedly. The target server now sends the "RESET" instruction to the client for all monitors, so this crash no longer occurs. (BZ#622278)

  • A typographical error in qemu-kvm output has been corrected. (BZ#646483)

  • Several superfluous dependencies were removed, including unnecessary dependencies on libcacard, CEGUI, X-libs and alsa packages. (BZ#670245)

  • The spice-server and spice-client packages use common libraries in Red Hat Enterprise Linux 6.1. This renders the following packages obsolete: cairo-spice 1.8.7.2 and earlier, ffmpeg-spice 0.4.9-1 and earlier, pixman-spice 0.13.3-6 and earlier, and spice-common 0.4.2-8 and earlier. These removed and obsoleted packages are now recorded in the spice-server.spec file.

Note that if both spice-client and spice-server are installed on a system, upgrading one of them will also cause the other to be upgraded. (BZ#674171)

  • Smart card (Common Access Card) support has been added to spice-server, allowing single sign-on and other card services such as signing and encryption. (BZ#674937)

All users requiring spice-server are advised to upgrade to this updated package, which adds these enhancements.
