Security and DRM Leftovers

Linux 5.15-rc3

So after a somewhat rocky merge window and second rc, things are now
actually looking pretty normal for rc3. Knock wood.

There are fixes all over, and the statistics look fairly regular, with
drivers dominating as they should (since they are most of the tree).
And outside of drivers, we have a fairly usual mix of changes -
architecture fixes, networking, filesystems, and tooling (the latter
being mostly kvm selftests).

Shortlog appended, it's not too long and easy to scan through to get a
flavor for the details if you happen to care.

Please do give it a whirl,

             Linus

Huawei launches OS openEuler, aims to construct 'ecological base of national digital infrastructure'

Chinese tech giant Huawei launched openEuler operating system (OS) on Saturday, another self-developed OS after the HarmonyOS, as it tries to "solve the domestic stranglehold problem of lacking its homegrown OS in basic technology," and build a full-scenario covered ecosystem to prepare for more US bans. The openEuler OS can be widely deployed in various forms of equipment such as servers, cloud computing and edge computing. Its application scenarios cover Information Technology, Communication Technology and Operational Technology to achieve unifying an operating system with multi-device support, according to the company's introduction. In the ICT field, Huawei provides products and solutions such as servers, storage, cloud services, edge computing, base stations, routers, industrial control among others, all of which need to be equipped with an OS. Huawei has therefore been building capabilities to achieve a unified OS architecture, and meet the demands of different application scenarios, the firm said on Saturday. The openEuler program was initially announced back in 2019 as an open source operating system. Today's launch is an updated one. Read more
