Do bazy kodu j\u0105dra Linux, na podstawie kt\u00f3rej na pocz\u0105tku lutego zostanie zbudowana wersja 6.19, wprowadzono kod podsystemu LUO (Live Update Orchestrator), opracowanego przez firm\u0119 Google do aktualizacji j\u0105dra w trybie na \u017cywo bez fizycznego restartu. Podsystem oparty jest na mechanizmie KHO (Kexec HandOver), kt\u00f3ry wcze\u015bniej zosta\u0142 dodany do j\u0105dra 6.16 i umo\u017cliwia uruchomienie nowego j\u0105dra ze starego bez utraty stanu systemu. <\/p>\n

Live Update Orchestrator umo\u017cliwia pe\u0142ne zrestartowanie i zaktualizowanie j\u0105dra bez zatrzymywania dzia\u0142ania oraz bez utraty stanu systemu, urz\u0105dze\u0144 i proces\u00f3w. Opr\u00f3cz funkcjonalno\u015bci KHO, podsystem LUO zachowuje stan urz\u0105dze\u0144 i pami\u0119ci operacyjnej, a tak\u017ce zapewnia ci\u0105g\u0142o\u015b\u0107 operacji zwi\u0105zanych z DMA oraz przetwarzaniem przerwa\u0144. Stan jest zachowywany a\u017c do prze\u0142\u0105czenia na nowe j\u0105dro i przywracany po uruchomieniu nowego j\u0105dra, bez zak\u0142\u00f3cania ci\u0105g\u0142ych operacji z urz\u0105dzeniami, realizowanych przez system i aplikacje w przestrzeni u\u017cytkownika. <\/p>\n

Cech\u0105 nowej serii poprawek jest mo\u017cliwo\u015b\u0107 zachowania deskryptor\u00f3w plik\u00f3w memfd w celu utrzymania stanu wa\u017cnych danych w pami\u0119ci mi\u0119dzy restartami, takich jak zawarto\u015b\u0107 pami\u0119ci operacyjnej. maszyn wirtualnych<\/a>. Jako podstawowy obszar zastosowa\u0144 podsystemu wymieniane jest szybkie aktualizowanie serwer\u00f3w<\/a> z systemami wirtualizacji opartymi na hipervizorze KVM, aby wyeliminowa\u0107 problemy z bezpiecze\u0144stwem i stabilno\u015bci\u0105 przy minimalnym czasie przestoju maszyn wirtualnych. Firma Google ju\u017c stosuje t\u0119 technologi\u0119 w swoich \u015brodowiskach roboczych. <\/p>\n

W odr\u00f3\u017cnieniu od livepatch, Ksplice, kpatch, kGraft i innych mechanizm\u00f3w stosowania poprawek na gor\u0105co, nowy podsystem nie ogranicza si\u0119 do mo\u017cliwo\u015bci stosowania pojedynczych poprawek do dzia\u0142aj\u0105cego j\u0105dra i pozwala na ca\u0142kowit\u0105 wymian\u0119 j\u0105dra. W przeciwie\u0144stwie do wywo\u0142ania kexec, podsystem LUO zachowuje stan urz\u0105dze\u0144 i podsystem\u00f3w j\u0105dra mi\u0119dzy restartami, podczas gdy wywo\u0142anie kexec dzia\u0142a jedynie jako bootloader, uruchamiaj\u0105cy nowe j\u0105dro z pe\u0142n\u0105 reinicjalizacj\u0105 systemu (odpowiednik restartu, ale bez przekazywania kontroli do oprogramowania uk\u0142adowego).
