| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commenters may not receive new versions of patches via the lists. Without a directed notification to them they might miss those new versions. This is frustrating for the patch developers as they don't receive their earned Reviewed-by. It is also frustrating for the commenters, as they might think their review got ignored or they have to dig up new versions from the archive manually. So encourage patch submitters to make sure that all commenters get notified also when no Reviewed-by was issued yet.

By adding this to the kernel as documentation we can more easily point to it e.g. from stable emails about failed backports, as well as allow the community to modify it over time if necessary. I've added this under process/ since it also has process/applying-patches.rst. Another interesting document is maintainer/rebasing-and-merging.rst which maybe should eventually refer to this one, but I'm leaving that as a future cleanup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtualization Kernel developers working on confidential computing for virtualized environments in x86 operate under a set of assumptions regarding the Linux kernel threat model that differs from the traditional view. Historically, the Linux threat model acknowledges attackers residing in userspace, as well as a limited set of external attackers that are able to interact with the kernel through networking or limited HW-specific exposed interfaces (e.g. USB, thunderbolt). The goal of this document is to explain additional attack vectors that arise in the virtualized confidential computing space.

Also, following the BPF instructions[1], to run the bpf selftests one would need to enter in the tools/testing/selftests/bpf/ directory, and then run make, which is not the standard way to run selftests per it's documentation.

The use of Linux on Itanium appears to be limited to enthusiasts that occasionally boot a fresh Linux kernel to see whether things are still working as intended, and perhaps to churn out some distro packages that are rarely used in practice. None of the original companies behind Itanium still produce or support any hardware or software for the architecture, and it is listed as 'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers that contributed on behalf of those companies (nor anyone else, for that matter) have been willing to support or maintain the architecture upstream or even be responsible for applying the odd fix. The Intel firmware team removed all IA-64 support from the Tianocore/EDK2 reference implementation of EFI in 2018. (Itanium is the original architecture for which EFI was developed, and the way Linux supports it deviates significantly from other architectures.) Some distros, such as Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have dropped support years ago. While the argument is being made [1] that there is a 'for the common good' angle to being able to build and run existing projects such as the Grid Community Toolkit [2] on Itanium for interoperability testing, the fact remains that none of those projects are known to be deployed on Linux/ia64, and very few people actually have access to such a system in the first place. Even if there were ways imaginable in which Linux/ia64 could be put to good use today, what matters is whether anyone is actually doing that, and this does not appear to be the case. There are no emulators widely available, and so boot testing Itanium is generally infeasible for ordinary contributors. GCC still supports IA-64 but its compile farm [3] no longer has any IA-64 machines. GLIBC would like to get rid of IA-64 [4] too because it would permit some overdue code cleanups. In summary, the benefits to the ecosystem of having IA-64 be part of it are mostly theoretical, whereas the maintenance overhead of keeping it supported is real. So let's rip off the band aid, and remove the IA-64 arch code entirely. This follows the timeline proposed by the Debian/ia64 maintainer [5], which removes support in a controlled manner, leaving IA-64 in a known good state in the most recent LTS release. Other projects will follow once the kernel support is removed.
