RHEL 8.3: Security updates and new admin functions

With the new 8.3 release, Red Hat is updating its Linux distribution for businesses. RHEL now disables Intel’s Transactional Synchronization Extensions (TSX) by default. This is done for security reasons, as the TSX Asynchronous Abort (TAA) vulnerability of certain Xeon processors represents a serious security hole.

If desired However, users activate TSX manually; it can also be switched off in the BIOS setup of most systems. TSX – formerly known as Transactional Memory – is primarily intended to accelerate databases. TAA has been known since 2018 and Intel drew severe criticism with its late security updates that do not fully fix them.

New for the System Roles Red Hat is also expanding its System Roles, which can be used to specify and automate configurations. Among other things, the support of kernel parameters, log settings as well as SAP HANA and SAP NetWeaver is new. In addition, the administrator can now use the system roles to make security configurations for Identity Management, Certificate Management and Network-Bound Disk Encryption (NBDE).

There is also an update for Tuned that improves the performance of the RHEL -System with preconfigured profiles optimized for the respective server architecture. Also on board are new SCAP profiles (Secure Content Automation Protocol) for the Center for Internet Security (CIS) and HIPAA, which is a US law for the protection of health information. With the SCAP profiles, companies are supposed to increase the security of their systems with the help of best practices and technical standards.

Furthermore, the application streams receive an update, which is now support including Node.js 14 and Ruby 2.7. The tool separates frameworks for developers, databases and container tools from core components of the operating system. There are also many updates for packages, readers can find details on this in the announcement of the release. The predecessor 8.2 saw the light of day in April 2020, while RHEL 8 2019 appeared and receives support for ten years.

Watch Dogs Legion – Performance test of RTX and DLSS graphics cards

The Watch Dogs series has been remembered as sandboxes with great ambitions, which, despite loud announcements and interesting patents, did not harm the position of Grand Theft Auto, but found a group faithful admirers. Each time, “Crackling Dogs” came with relatively high hardware requirements, but the next installment, in addition to standard graphics options, also includes ray tracing, DLSS. The impact of additional goodies will of course be subject to the Watch Dogs Legion performance test, albeit without the GeForce RTX dedicated functions 1920 / 3000 will also be available. What equipment do you need to calmly wander the streets of London and fight for freedom?

Watch Dogs has had a serious history in its history. metamorphosis, because each subsequent edition changed the atmosphere to a noticeably looser one. One was a dark story about the cold revenge of an injured man, two of them told about the subversive actions of a homeland-hacker group, while three showed the fight against the repressive system in an even more chaotic and exaggerated form. The title Legion is a metaphorical reference to a disobedient society, whose representatives belonging to various professions, social classes, races and religions organize a militant underground against the vile organization ruling the city. Literally anyone can become a subversive, because in the new incarnation of Watch Dogs one hero has been replaced with a whole bunch of not very expressive NPCs. This approach will not suit everyone, as well as the greater emphasis on developing and retrofitting agents, but the rest of the mechanics remained roughly the old way – bypassing security, freely moving around the agglomeration, manipulating urban infrastructure, etc.

Watch Dogs Legion brings not only a change of environment, gameplay rules and story building, but also introduces new graphics options dedicated to GeForce RTX 2000 / 3000 – ray tracing and DLSS.

Ubisoft has carefully prepared the hardware requirements, divided into RTX OFF and RTX ON categories together with active DLSS, because the developer lists only NVIDIA products in place of the graphics card , I chose the equivalents from the AMD stable by myself. Basic computer for Watch Dogs Legion, allowing to enable High settings in resolution 1920 x 1080, should have AMD Ryzen 5 processor 1600 / Intel Core i7 – 4790 and a graphics card like NVDIA GeForce GTX 890 / AMD Radeon RX 580 Requirements for 2560 x 1440 High rise to AMD Ryzen 5 3600 / Intel Core i7 – 9700 K and GeForce RTX 2060 SUPER / AMD Radeon RX 5700. To play 3840 x 2160 must have AMD Ryzen 7 3700 X / Intel Core i7 – 9700 K and GeForce RTX 2080 Ti / AMD Radeon VII. If you want to enable ray tracing and DLSS, the requirements for processors are of course increasing, but above all for graphics systems, where, depending on the resolution, you need NVIDIA GeForce RTX 2000 (1920 x 1080), GeForce RTX 3070 (2560 x 1440 and GeForce RTX 3080 (3840 x 2160).

Official materials of the manufacturer do not mention the name the graphics engine on which Watch Dogs Legion was created, so it can only be assumed that the modified engine of the predecessor (Disr upt). On the other hand, however, some distinctive options have disappeared, which could point to a closer origin to Anvil Next driving the Assassin’s Creed franchise. Anyway, DirectX is finally introduced 10, which should be quite useful for large open world production that likes to pass a lot of data through the CPU. The use of a newer API has forced the implementation of ray tracing responsible for realistic reflections in real time visible in, among others, puddles, windows, wet surfaces, etc. The developer together with NVIDIA has also introduced the DLSS technique available in four variants. Both of the above goodies are dedicated to owners of NVIDIA GeForce RTX graphics cards 2000 and RTX 3000, while the latter Watch Dogs Legion will be added for free. All GeForc models e values ​​in this test were provided by KFA2.

HUAWEI: via the US ban? Semiconductor companies can supply the Chinese company

There seems to have been a green light from part of the US Department of Commerce regarding the semiconductor situation of HUAWEI. American companies seem to have received the green light to supply the Chinese company. On one condition: that these are not used to power modems for 5G networks.

Huawei 5G

New turning point in the affair between HUAWEI and the USA after the latter has blocked all types of concessions for months to American companies in supplying or selling their components or even their services to the Chinese company. A ban that weighed heavily on HUAWEI s especially on the mobile division that had to roll up its sleeves, as they say, and started creating its own operating system, its own services for developers, its own store for applications and all that. it concerns precisely the world of smartphones at the service level.

The problem, however, also concerned the impossibility of receiving fundamental components from American companies for making smartphones: we are talking about semiconductors but also about displays. Now, a few days later, from the news of the first authorization by the USA against Samsung Display, which was able to restart supplying HAUWEI with its panels, here comes a new good news concerning semiconductors.

HUAWEI: green light from the USA. Will it be the right time?

According to the words of the Financial Times, the major semiconductor companies which supplied their own HUAWEI, would have been given the green light by the US Department of Commerce to be able to sell and therefore concretely ” refresh ” HUAWEI without any more limitations or blocks. In this case, the US would have already allowed Samsung to produce and sell panels for smartphone screens to the Chinese company. The same fate would also be happening to Sony and OmniVision for the supply of photographic sensors. And not just because other semiconductor and memory companies would also be licensed to market their products to HUAWEI.

There would be only one condition to the permit: the components cannot be used by HUAWEI for the production of network equipment 5G such as classic modems. The only condition for the green light would be this from the US government. A choice that will therefore weigh on the business division of HUAWEI, essentially the one that is making products for the new 5G network. That very division would bother the US a lot but it is clear that in this case not giving American companies the opportunity to sell their products to HUAWEI was creating economic problems for the companies themselves and for the US economy.

Hence the lightening of the conditions that make the game of HUAWEI, part consumer , definitely easier and above all profitable since they can get back into the game with smartphones. We know, according to anonymous sources, that it was precisely on semiconductors that the Chinese company seemed to have implementation problems with the Kirin 9000 that could have been made with stocks only until March 2021. Now this problem will no longer exist and HUAWEI will be able to go back to working with TSMC , to name one, in the realization of the main components of their smartphones. And Google? In this case the question seems to be decidedly more complicated even if this opening could also be the antithesis of Google’s return to HUAWEI smartphones. Who knows, never say never.
