Updated spice-server packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol 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 Kernel-based Virtual Machine (KVM) hypervisor or on Red Hat Enterprise Virtualization Hypervisors.
The spice-server packages have been upgraded to upstream version 0.10.1, which fixes multiple bugs and adds multiple enhancements. (BZ#758089)
- Prior to this update, the smart card channel looked for the error code at the wrong location. As a consequence, the error messages contained random code instead of the actual error code. This update modifies the smart card channel code so that correct error messages are now sent.
- Prior to this update, the server rejected connections without logging any information to the qemu log if the client provided a wrong password. This update modifies qemu-kvm so that the messages "Invalid password" or "Ticket has expired" are sent when the client provides a wrong password.
- Prior to this update, qemu did not log X.509 files. As a consequence, no output regarding certificates or keys was available. This update modifies the underlying code so that information on X.509 files is now available.
- Prior to this update, the "struct sockaddr" code in the spice server library API was too short to hold longer IPv6 addresses. As a consequence, the reported IPv6 address appeared to be broken or incomplete. This update modifies the underlying code to use "struct sockaddr_storate" that can now hold complete IPV6 addresses.
- Prior to this update, the default lifetime of the "SpiceChannelEventInfo" event was too short for the "main_dispatcher_handle_channel" event. As a consequence, freed memory could be accessed after the RedsStream was freed for the cursor and display channels. This update allocates the "SpiceChannelEventInfo" event together with allocating the "RedsStream" event, and deallocates it only after the "DESTROY" event.
- Prior to this update, the display driver could send bitmaps to the spice server that contained video frames, but were larger than the frames sent before. As a consequence, the larger frames were not synchronized with the video stream, and their display time could differ from the display time of other frames and the playback seemed to skip and interrupt. With this update, large bitmaps are directly attached to the video stream they contain. Now, the playback is smooth and no longer interrupts.
- Prior to this update, USB devices could not be redirected over the network. This update adds USB redirection support to the to spice-server.
All users requiring spice-server are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
