Genode OS Framework release 20.05 | 2020-05-28
##############################################
| Version 20.05 wraps up the consolidation of Noux with the C runtime,
| advances the device-driver infrastructure and virtualization support on ARM,
| reaches feature-completion of our block encryptor, and leverages seccomp for
| sandboxing components on top of Linux.
It has become almost a tradition to dedicate the spring release to topics
under the hood of the Genode OS framework, taking the time for careful
consolidation, and architectural improvements.
On the latter account, the Linux version gained an architectural revamp of its
inter-component communication model, leveraging the combination of the
seccomp and epoll kernel mechanisms to enable Genode's capability-based
security concept on this kernel. The new version applies strict sandboxing
to each component individually. In particular, the host file system is
shielded from Genode components and Genode's least-privilege access-control
scheme comes into effect.
As the second prominent architectural topic, the release features new
device-driver infrastructure for the ARM universe along with a unified
version of the formerly distinct virtual machine monitors for ARMv7 and
ARMv8. These are important steps to bring Genode on ARM to parity with the
x86 version.
Further highlights of the release are the first feature-complete version
of our custom block-encryption component, the improved management of CPU
affinities on x86, and new tracing utilities. Last but not least, the
release is accompanied with an updated version of the Genode Foundations
book, reflecting the changes of the framework since one year ago.
