Per l'inclusione nel kernel Linux 5.20 (\u00e8 possibile che il ramo assuma il numero 6.0), \u00e8 stato proposto un insieme di patch che implementano il meccanismo RV (Runtime Verification), che fornisce strumenti per verificare la correttezza operativa in sistemi ad alta affidabilit\u00e0, garantendo l'assenza di guasti. La verifica avviene durante l'esecuzione attraverso l'aggancio di gestori ai punti di tracciamento, confrontando il percorso effettivo di esecuzione con un modello deterministico di riferimento predefinito, che definisce il comportamento atteso del sistema. <\/p>\n

Le informazioni dai punti di tracciamento trasferiscono il modello da uno stato all'altro e, se il nuovo stato non corrisponde ai parametri del modello, viene generato un avviso o il kernel viene portato nello stato \"panic\" (si presume che i sistemi ad alta affidabilit\u00e0 possano rilevare tali situazioni e reagire di conseguenza). Il modello dell'automa, che definisce le transizioni da uno stato all'altro, viene esportato nel formato \"dot\" (graphviz) e successivamente tradotto utilizzando lo strumento dot2c in una rappresentazione in linguaggio C, che viene quindi caricata come modulo del kernel, monitorando le deviazioni dell'esecuzione dal modello predeterminato.

\"Per<\/center> <\/p>\n

La verifica con il modello durante l'esecuzione \u00e8 posizionata come un metodo pi\u00f9 leggero e semplice da implementare nella pratica per confermare la correttezza operativa in sistemi critici, integrando i metodi classici di verifica della affidabilit\u00e0, come la verifica del modello e le dimostrazioni matematiche di conformit\u00e0 del codice alle specifiche definite in linguaggio formale. Tra i vantaggi dell'RV si evidenzia la possibilit\u00e0 di garantire una rigorosa verifica senza necessit\u00e0 di una implementazione completa dell'intero sistema in linguaggio di modellazione, nonch\u00e9 una risposta flessibile a eventi imprevisti, ad esempio per bloccare la diffusione di guasti in sistemi critici.
