Tianocore gets Brotli compression support

BinX Song of Intel has submitted a patch to EDK2 with support for Google’s Brotli compression algorithm.

[PATCH 0/4] MdeModulePkg/BaseTools: Add Brotli algorithm support

Brotli algorithm has a little less compress ratio than Lzma, but has better decompress performance than it.  Add Brotli algorithm support, include Brotli decompression library and tool set.

Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

Siemens industrial plant firmware malware

Quoting the Register article:

[…]Malware posing as legitimate firmware for Siemens control gear has apparently infected industrial equipment worldwide over the past four years. The cyber-nasty is packaged as software to be installed on Siemens programmable logic controllers (PLC), we’re told. At least 10 industrial plants – seven in the US – were found running the infected firmware, a study by industrial cybersecurity firm Dragos claims. According to the Texas-based biz, this particular malware was specifically thrown at industrial control equipment. Exactly what it does, or did, is not explained, although it is described as “crimeware”. […]

The Dragos blog post is worth reading:

UTTOS: UEFI testing research

A paper from October 2016 that I just noticed:

UTTOS: A Tool for Testing UEFI Code in OS Environment

Unit tests are one of the most widely used tools to assure a minimal level of quality and compliance during development. However, they are not used in many projects where development takes place at low-level contexts. The main reason is that unit test development itself demands more time and becomes expensive in this context and tools that assist test creation are rare or absent. In UEFI development this scenario matches the reality of most teams and unit testing as well as other testing techniques are often not used. To address this fault we propose UTTOS, a tool that parses EDKII build configuration files, mocks the UEFI-specific functions for C development and enables UEFI test suite code to run in the operating system. We show that UTTOS is able to run the test suit in the operating system and save development time.

Redfish and SDI

Redfish Emerges as an Interoperability Standard for SDI
The world’s data centers are working to adopt Software Defined Infrastructure (SDI) – but they are far from reaching their goals. The single biggest challenge in SDI is achieving interoperability between many kinds of hardware. Without that, a data center’s systems become a Tower of Babel, preventing IT system admins from seeing a unified view of all resources – and managing them. Built to leverage virtualized infrastructure, SDI will be easier to achieve if there are more bridges between platforms – leading to better management. This blog focuses on an emerging management standard called Redfish, which is designed to help make SDI a day-to-day reality for hybrid cloud.[…]
