Projektet udvikler <strong>Multikernel Technologies<\/strong>, et firma der promoverer split-kernel \/ multikernel arkitektur til Linux. Cong Wang, virksomhedens grundl\u00e6gger, pr\u00e6senterede KernelScript ved Linux Foundation Open Source Summit; projektkoden er offentliggjort p\u00e5 GitHub under licensen <strong>Apache 2.0<\/strong>.<\/p>\n<p><\/noindex><\/noindex><br \/>\n<noindex><\/p>\n<p>eBPF (Extended Berkeley Packet Filter) \u2014 en teknologi der tillader k\u00f8rsel af sm\u00e5 programmer direkte i Linux-kernen, uden at \u00e6ndre dens kode og uden at riskere systemets stabilitet. eBPF hj\u00e6lper med at l\u00f8se mange opgaver, fra overv\u00e5gning af ydeevne til sikkerhed og netv\u00e6rksoptimering. For eksempel kan eBPF bruges til at spore systemopkald, netv\u00e6rkstrafik og andre begivenheder i realtid. Dette g\u00f8r det muligt at finde flaskehalse i ydeevnen og optimere systemet (<a rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/companies\/selectel\/articles\/887272\/\">Habr<\/a>).<\/p>\n<p><\/noindex><\/p>\n<p>Id\u00e9en bag KernelScript er at g\u00f8re udviklingen af eBPF mindre smertefuld end ved brug af kombinationen C + libbpf, og ikke kun begr\u00e6nse sig til tracing, som bpftrace g\u00f8r. Udviklerne beskriver sproget som en type-sikker DSL, der kombinerer <strong>eBPF<\/strong>, brugerdefineret rum og kernelspace-udvikling: fra en enkelt kildefil skal compileren generere kode til eBPF-programmer, userspace-delen og integration med kernel-moduler gennem kfunc.<\/p>\n<p>De angivne funktioner af KernelScript:<\/p>\n<ul>\n<li>\n<p><strong>Kompilering til forskellige m\u00e5l fra en enkelt fil<\/strong> \u2014 funktioner med attributter som @xdp, @tc, @helper og @kfunc henf\u00f8res automatisk til den relevante del: XDP\/TC-programmet, helper-funktionen, kernel-funktionen eller almindelig userspace-kode.<\/p>\n<\/li>\n<li>\n<p><strong>Automatisering af tail calls<\/strong> \u2014 i stedet for manuel ops\u00e6tning af program array og kald af bpf_tail_call() opfordres udvikleren til at skrive et almindeligt kald til en anden funktion, mens lavniveau eBPF-kodegenerering overlades til compileren.<\/p>\n<\/li>\n<li>\n<p><strong>Forenklet arbejde med dynptr og eBPF maps<\/strong> \u2014 sproget skjuler en del af det manuelle arbejde med bpf_ringbuf_reserve_dynptr, bpf_dynptr_write og lignende API. eBPF-kort kan bruges som globale variabler, der er tilg\u00e6ngelige for forskellige programmer.<\/p>\n<\/li>\n<li>\n<p><strong>Kontrol af livscyklussen for programmer<\/strong> \u2014 eBPF-programmer pr\u00e6senteres som typede v\u00e6rdier, hvilket if\u00f8lge forfatternes plan forhindrer fejl som f.eks. at fors\u00f8ge at udf\u00f8re attach() f\u00f8r successful load().<\/p>\n<\/li>\n<li>\n<p><strong>Support for kfunc<\/strong> KernelScript muligg\u00f8r deklarering af funktioner med @kfunc-attributten, som k\u00f8rer i kernens rum og kan kaldes fra eBPF-programmer; der lover automatisk generation af kernel modul og BTF-registreringer.<\/p>\n<\/li>\n<li>\n<p><strong>Underst\u00f8ttelse af de grundl\u00e6ggende typer eBPF-programmer<\/strong> \u2014 README viser eksempler for XDP, TC, probe-programmer og perf_event, inklusive arbejde med hardware-ydeevnem\u00e5lere.<\/p>\n<\/li>\n<\/ul>\n<p>Forfatterne understreger, at KernelScript ikke er en erstatning for Linux-kernen eller en ny eBPF-runtime. Det er snarere en compiler og et h\u00f8jniveau-sprog, der skal generere de velkendte lavniveau-komponenter: eBPF-kode, userspace-ladere, Makefile og, om n\u00f8dvendigt, kernel modul.<\/p>\n<p>Projektet b\u00f8r i \u00f8jeblikket betragtes som et tidligt eksperiment.
