I kodebasen af Linux-kernen, som release 6.19 vil blive dannet ud fra i begyndelsen af februar, er koden til LUO (Live Update Orchestrator) subsystemet blevet accepteret. Denne teknologi, udviklet af Google, muligg\u00f8r opdatering af kernen i Live-tilstand uden fysisk genstart. Subsystemet er baseret p\u00e5 KHO-mekanikken (Kexec HandOver), som tidligere blev tilf\u00f8jet i kerneversion 6.16 og tillader opstart af en ny kerne fra den gamle uden tab af systemtilstand. <\/p>\n

Live Update Orchestrator g\u00f8r det muligt at genstarte og opdatere kernen uden at stoppe arbejdet og uden at miste systemtilstand, enheder og processer. Ud over KHO-funktionaliteten bevarer LUO subsystemet tilstanden af enheder og RAM, samt sikrer kontinuitet i operationer relateret til DMA og interrupt behandling. Tilstanden bevares indtil omkoblingen til den nye kerne og genoprettes efter aktivering af den nye kerne uden at forstyrre kontinuerlige operationer med enheder udf\u00f8rt af systemet og applikationer i brugerrummet. <\/p>\n

En s\u00e6rlig egenskab ved den nye serie patcher er muligheden for at bevare filh\u00e5ndtag memfd for at opretholde tilstanden af vigtige data i hukommelsen mellem genstarter, s\u00e5som indholdet i RAM. virtual machines<\/a>. Som grundl\u00e6ggende anvendelsesomr\u00e5de for subsystemet n\u00e6vnes hurtig opdatering servere<\/a> med virtualiseringssystemer baseret p\u00e5 KVM-hypervisoren for at l\u00f8se problemer med sikkerhed og stabilitet med minimal nedetid for virtuelle maskiner. Google anvender allerede denne teknologi i sine arbejdsomgivelser. <\/p>\n

I mods\u00e6tning til livepatch, Ksplice, kpatch, kGraft og andre metoder til hot patching, er det nye subsystem ikke begr\u00e6nset til at kunne anvende individuelle rettelser til den k\u00f8rende kerne, men muligg\u00f8r fuldst\u00e6ndig udskiftning af kernen. I mods\u00e6tning til kexec-anrop bevarer LUO subsystemet tilstanden af enheder og kernesubsystemer mellem genstarter, mens kexec-anropet kun fungerer som en loader, der starter en ny kerne med fuld geninitialisering af systemet (\u00e6kvivalent med en genstart, men uden at overf\u00f8re kontrol til firmware).
