This security issue was fixed:

- CVE-2018-3639: Spectre v4 vulnerability mitigation support for KVM guests (bsc#1092885).

 Systems with microprocessors utilizing speculative execution and speculative
 execution of memory reads before the addresses of all prior memory writes are
 known may allow unauthorized disclosure of information to an attacker with
 local user access via a side-channel analysis.

 This patch permits the new x86 cpu feature flag named 'ssbd' to be
 presented to the guest, given that the host has this feature, and
 KVM exposes it to the guest as well.

 For this feature to be enabled please use the qemu commandline
 -cpu $MODEL,+spec-ctrl,+ssbd
 so the guest OS can take advantage of the feature.

 spec-ctrl and ssbd support is also required in the host.

This feature was added:

- Add support for block resize support for xen disks through the monitor

This non-security issue was fixed:

- bsc#1079405: Add new look up path 'sys/class/tpm' for tpm cancel path based
 on Linux 4.0 change");
