Linux Kernell to be Updated to 4.18

Another update brings new features and improvements
14 August 2018   243

Linus Torvalds announced the release of the Linux kernel 4.18. The changes affect 13,067 files. Developers were able to make the kernel more compact by removing 677,480 and adding 578,788 code blocks.

It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announcement as "pending") and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering  fix).

Linus Torvalds

Creator, Linux

Two months passed since the announcement of the release candidate Linux 4.18-rc1, the developers conducted testing and eliminated kernel problems.

Most Important Changes
Changes affected the work with processors, file system and data storage, graphics processing. Some new features of Linux 4.18 should be highlighted:

  • Basic support for Qualcomm Snapdragon 845 SoC.
  • Support for Steam Controller from Valve.
  • The core infrastructure is added to the kernel for BPFILTER, which processes the iptables API requests and passes them to BPF programs.
  • DRM-driver AMDGPU now supports VegaM graphics processing on Intel Kabylake-G CPUs, as well as the forthcoming graphics card known as AMD Vega 20 GPU.
  • Various AMDGPU power management enhancements, such as profiles for Vega.
  • The AMDKFD kernel driver now supports GFX9 / Vega hardware.
  • Intel finalized support for the micro-architecture of Ice Lake.
  • Implemented by DM Writecache, which can be used to cache write operations of blocks on SSD-drives or in permanent memory.
  • Improved support for USB 3.2 and USB Type-C.
  • Already started work on a large update of Linux 4.19. It is assumed that this will be the latest version before 5.0.

Linux, open source OS, is developing rapidly. Only in 2018 came out the kernel versions 4.15, 4.16, 4.17, and now 4.18.

Cloudflare to Develop IPFS Gateway

According to the developers, new gateway will allow to create P2P based websites

Cloudflare told about the IPFS gateway, which will allow creating sites based on P2P network. The company said that access to content will be done without having to install special software on the devices.

As a technology feature, Cloudflare experts note decentralization. Using a standard network scheme with servers involves physical storage of data in one place. Hacking the server or damage to communications as a result of an emergency (for example, a natural disaster) will lead to inaccessibility of information or its loss. The same is threatened with information if the server owner has decided to refuse it.

The IPFS gateway combines computers, on each of which some information is stored, to the worldwide network. Therefore, the inaccessibility of one computer does not mean that the content can not be viewed or downloaded. Therefore, the key differences are two:

  1. With IPFS, anyone can freely post information instead of storing it on remote servers and paying for their services.
  2. Requests for access to data are carried out using cryptographic hashing, rather than by IP address. The query data is converted to a series of letters and numbers, by which the system finds the required files. For example, the query for any information will not like "get information that is located at IP address", but the kind "get information with hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy". This hash sum is part of the desired file and is on several computers.

The system automatically determines the authenticity of the file. If we take as an example a query with a hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy, then when receiving the information it should remain the same. If the hash value differs, then the file has been changed. In other words, the hash-sum can be represented as a unique fingerprint:

Supporters of decentralization are also in a number of other companies. Mozilla employees believe that consumers should not be tied to a particular product, brand or platform. In early August 2018, developers published a version of the IoT gateway Things Gateway 0.5. In it, they realized the possibility of loading third-party icons and an interface for complex devices.
