La compagnia assicurativa GEICO ha pubblicato una versione preliminare dello strumento TuxTape, che consente di implementare una propria infrastruttura per la creazione, l'assemblaggio e la distribuzione di live patch per il kernel Linux. I live patch permettono di applicare correzioni al kernel Linux al volo, senza riavviare e fermare il sistema. Il codice del progetto \u00e8 scritto in Rust ed \u00e8 distribuito sotto la licenza Apache 2.0. <\/p>\n

I live patch che risolvono vulnerabilit\u00e0 sono forniti da aziende come Red Hat, Oracle, Canonical e SUSE per le loro distribuzioni, ma l'unico strumento a disposizione \u00e8 quello di basso livello per lavorare con i patch, mentre i patch stessi vengono creati dietro porte chiuse. Le distribuzioni Gentoo e Debian hanno tentato di sviluppare progetti aperti elivepatch e linux-livepatching, ma il primo \u00e8 abbandonato da sei anni, mentre il secondo si \u00e8 fermato alla fase di creazione di un prototipo di test. <\/p>\n

TuxTape \u00e8 progettato per organizzare un sistema autonomo per la creazione e distribuzione di live patch, indipendente dai fornitori esterni e adattabile a qualsiasi kernel Linux, non solo ai pacchetti con kernel di specifiche distribuzioni. TuxTape pu\u00f2 generare live patch compatibili con lo strumento kpatch sviluppato da Red Hat (oltre a kpatch esistono strumenti simili: kGraft di SUSE, Ksplice di Oracle e il livepatch universale). I patch sono generati come moduli del kernel caricabili, che sostituiscono le funzioni nel kernel utilizzando il sottosistema ftrace per indirizzare alle nuove funzioni incluse nel modulo.

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

TuxTape pu\u00f2 monitorare le informazioni sulle vulnerabilit\u00e0 nel kernel Linux, pubblicate nella mailing list linux-cve-announce e nel repository Git, classificare le vulnerabilit\u00e0 in base al livello di gravit\u00e0, determinare l'applicabilit\u00e0 ai kernel Linux supportati e generare live patch basati su normali patch per i rami LTS del kernel. L'applicabilit\u00e0 delle patch originali viene valutata tramite il profilo delle compilazioni del kernel. I patch con vulnerabilit\u00e0 che non colpiscono il kernel target vengono ignorati. <\/p>\n

TuxTape comprende un sistema per il monitoraggio delle nuove vulnerabilit\u00e0 nel kernel, un costruttore di DB di patch e vulnerabilit\u00e0, un server<\/a> per la memorizzazione dei metadati, un sistema di gestione delle compilazioni del kernel, un assemblatore del kernel, un generatore di patch, un archivio di patch, un client per ricevere patch per host finali e un'interfaccia interattiva per gestire la creazione di live patch.

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

Lo sviluppo \u00e8 attualmente in fase di prototipo sperimentale. Per i test iniziali sono stati proposti: tuxtape-cve-parser per analizzare le informazioni sulle vulnerabilit\u00e0 e costruire un database con le patch; tuxtape-server con l'implementazione dell'interfaccia gRPC per i servizi che generano patch; tuxtape-kernel-builder per compilare il kernel in una configurazione specifica e generare il profilo di compilazione; tuxtape-dashboard — interfaccia console per la revisione e la creazione di live-patch basati su patch originali ottenute da tuxtape-server.
