Gli utenti dei sistemi che utilizzano il meccanismo zRAM per la compressione dello spazio di swap in memoria hanno riscontrato un problema che causa il fallimento dell'avvio dopo l'aggiornamento del kernel Linux alla versione 6.12. Il problema si manifesta in Gentoo, Void e altre distribuzioni che supportano zRAM e forniscono pacchetti con nuove versioni del kernel. <\/p>\n

La causa del fallimento \u00e8 stata una modifica introdotta nel kernel 6.12 che aggiunge la possibilit\u00e0 di configurare gli algoritmi di compressione durante il runtime. Di conseguenza, nella configurazione Kconfig \u00e8 stata modificata la logica di selezione degli algoritmi di compressione disponibili al momento della compilazione del kernel. Questa modifica ha portato a problemi nelle distribuzioni che si sono basate sulle impostazioni predefinite e non hanno abilitato separatamente tutti gli algoritmi zRAM disponibili nella configurazione Kconfig per il kernel 6.12. <\/p>\n

Dopo l'aggiornamento al kernel 6.12, in distribuzioni simili \u00e8 rimasto disponibile per la selezione solo l'algoritmo di compressione di base impostato per impostazione predefinita, e non tutti gli algoritmi supportati. Pertanto, tentando di abilitare algoritmi zRAM che non corrispondono a quello di default, si verificava un errore durante il boot. Ad esempio, selezionando l'algoritmo lz4 durante il boot si riceveva l'errore \u00abzramctl: \/dev\/zram0: failed to set algorithm: Invalid argument\u00bb, poich\u00e9 rimaneva solo il supporto per lzo, invece dei precedenti supporti per lzo, lz4, lz4hc, 842 e zstd. <\/p>\n

Il problema si risolve abilitando in Kconfig ciascun backend di compressione separatamente (le impostazioni CONFIG_ZRAM_BACKEND_* sono state aggiunte nel kernel 6.12): CONFIG_ZRAM_BACKEND_LZ4=y CONFIG_ZRAM_BACKEND_LZ4HC=y CONFIG_ZRAM_BACKEND_ZSTD=y CONFIG_ZRAM_BACKEND_842=y CONFIG_ZRAM_DEF_COMP_LZO=y CONFIG_ZRAM_DEF_COMP=\"lzo\"
