I kodbasen f\u00f6r Linux-k\u00e4rnan, som i b\u00f6rjan av februari kommer att ge upphov till version 6.19, har kod f\u00f6r subsystemet LUO (Live Update Orchestrator) antagits. Det har utvecklats av Google f\u00f6r att uppdatera k\u00e4rnan i realtid utan fysisk omstart. Subsystemet baseras p\u00e5 mekanismen KHO (Kexec HandOver), som tidigare togs in i k\u00e4rna 6.16 och m\u00f6jligg\u00f6r att starta en ny k\u00e4rna fr\u00e5n den gamla utan att f\u00f6rlora systemets tillst\u00e5nd. <\/p>\n

Live Update Orchestrator m\u00f6jligg\u00f6r en fullst\u00e4ndig omstart och uppdatering av k\u00e4rnan utan att stoppa verksamheten och utan att f\u00f6rlora systemets, enheternas och processernas tillst\u00e5nd. Ut\u00f6ver KHO:s funktionalitet sparar subsystemet LUO tillst\u00e5ndet f\u00f6r enheter och RAM-minne samt s\u00e4kerst\u00e4ller oavbruten funktion av operationer relaterade till DMA och avbrottshantering. Tillst\u00e5ndet sparas fram tills \u00f6verg\u00e5ngen till den nya k\u00e4rnan och \u00e5terst\u00e4lls efter att den nya k\u00e4rnan aktiverats utan att st\u00f6ra oavbrutna operationer med enheterna som utf\u00f6rs av systemet och anv\u00e4ndarapplikationerna. <\/p>\n

En speciell funktion hos den nya serie patchar \u00e4r m\u00f6jligheten att spara filbeskrivare memfd f\u00f6r att beh\u00e5lla tillst\u00e5ndet f\u00f6r viktiga data i minnet mellan omstarter, s\u00e5som inneh\u00e5llet i RAM-minnet. virtuella maskiner<\/a>Som grundl\u00e4ggande anv\u00e4ndningsomr\u00e5de f\u00f6r subsystemet n\u00e4mns snabb uppdatering servrar<\/a> med virtualiseringssystem baserade p\u00e5 hypervisorn KVM, f\u00f6r att \u00e5tg\u00e4rda s\u00e4kerhets- och stabilitetsproblem med minimal stillest\u00e5ndstid f\u00f6r virtuella maskiner. Google anv\u00e4nder redan denna teknologi i sina arbetsmilj\u00f6er. <\/p>\n

Till skillnad fr\u00e5n livepatch, Ksplice, kpatch, kGraft och andra mekanismer f\u00f6r live patching, begr\u00e4nsar sig det nya subsystemet inte till att till\u00e4mpa enskilda korrigeringar p\u00e5 den aktiva k\u00e4rnan och till\u00e5ter en fullst\u00e4ndig ers\u00e4ttning av k\u00e4rnan. Till skillnad fr\u00e5n att anropa kexec, bevarar subsystemet LUO tillst\u00e5ndet f\u00f6r enheter och subsystem mellan omstarter, medan anropet av kexec fungerar bara som en laddare som startar en ny k\u00e4rna med fullst\u00e4ndig \u00e5terinitialisering av systemet (motsvarar omstart men utan att \u00f6verf\u00f6ra kontrollen till firmwaren).
