How Red Hat is making money on the public cloud with a hybrid approach
Red Hat hasn't traditionally played much of a part in public clouds, a fact its CEO Jim Whitehurst underscored in Red Hat's recent earnings call. Though the company is now dabbling in a true elastic/consumption-based delivery and pricing model via OpenShift, Red Hat remains a primarily on-premises business that only feints toward a true cloud model in terms of service delivery.
Ironically, the hybrid cloud may be the trend that gets Red Hat fully planted in the public cloud.
GE, Bosch and open source could bring more IoT tools
The two companies, both big players in industrial IoT, said they will establish a core IoT software stack based on open-source software. They plan to integrate parts of GE's Predix operating system with the Bosch IoT Suite in ways that will make complementary software services from each available on the other.
The work will take place in several existing open-source projects under the Eclipse Foundation. These projects are creating code for things like messaging, user authentication, access control and device descriptions. Through the Eclipse projects, other vendors also will be able to create software services that are compatible with Predix and Bosch IoT Suite, said Greg Petroff, executive director of platform evangelism at GE Software.
Unsafe at any clock speed: Linux kernel security needs a rethink
The Linux kernel today faces an unprecedented safety crisis. Much like when Ralph Nader famously told the American public that their cars were "unsafe at any speed" back in 1965, numerous security developers told the 2016 Linux Security Summit in Toronto that the operating system needs a total rethink to keep it fit for purpose.
No longer the niche concern of years past, Linux today underpins the server farms that run the cloud, more than a billion Android phones, and not to mention the coming tsunami of grossly insecure devices that will be hitched to the Internet of Things. Today's world runs on Linux, and the security of its kernel is a single point of failure that will affect the safety and well-being of almost every human being on the planet in one way or another.

ON.Lab’s ONOS Project noted its eighth SDN platform release expands southbound and northbound protocol, legacy device support
The telecommunications market’s choice of software-defined networking platforms continues to blossom, with the Open Networking Laboratory’s Open Network Operating System Project releasing its latest SDN platform variant under the “Hummingbird” tag.
OPNFV today issued its third software release, ending the agonizing six-month period in which folks had to pronounce and spell Brahmaputra. (See OPNFV Issues Third Software Release.)
This latest release continues the river theme but is sensibly named Colorado: It has other advantages as well, namely support for key features such as security, IPv6, service function chaining (SFC) testing, virtual private networks and more.
In addition, Colorado is laying some key groundwork for what lies ahead as the industry comes to terms with the MANO (management and network orchestration) dilemma, says Heather Kirksey, Open Platform for NFV Project Inc. 's executive director.
With AMD's forthcoming Zen processors is support for some new memory encryption technologies that are of particular benefit for virtualized environments.
I wrote about Linux patches for AMD memory encryption earlier this year while since then more information has come to light. At last month's Linux Security Summit, David Kaplan presented on these technologies coming with Zen; only today I had come across the slide deck for this presentation.
The technologies come down to Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). SME provides memory encryption on a per-page-table basis using AMD's ARM-based security co-processor. AMD SME + SEV are designed against both user-access attacks and physical access attacks with a particular focus on VM / hypervisor security.
Fuzz testing (or fuzzing) is a software testing technique that involves passing invalid or random data to a program and observing the results, such as crashes or other failures. Bamvor Jian Zhang of Huawei, who will be speaking at LinuxCon Europe, realized that existing fuzz testing tools -- such as trinity -- can generate random or boundary values for syscall parameters and inject them into the kernel, but they don’t validate whether the results of those syscalls are correct.
While GLAMOR has already been around for a number of years as a means of providing generic X11 2D acceleration over OpenGL for the X.Org Server, it's a seemingly never-ending process to optimize its code-paths for best performance. More improvements are en route for making GLAMOR 2D faster, which should especially be helpful for Raspberry Pi users making use of the VC4 driver stack on this very slow-speed hardware.
Benefits to the GLAMOR code in the X.Org Server obviously have the potential to benefit all users of this acceleration mechanism for code going into the xorg-server code-base as opposed to an individual GL driver, but for Raspberry Pi users in particular there is some efforts ongoing by Broadcom's Eric Anholt as well as Keith Packard's never-ending tinkering with the X Server code. GLAMOR continues to be used by default for all AMD GCN GPUs, Nouveau for the latest generations of GPU too, VC4 2D is only supported with GLAMOR, and optionally by other DDX drivers too.
