Osiguravaju\u0107a kompanija GEICO objavila je preliminarnu verziju alata TuxTape, koji omogu\u0107uje postavljanje vlastite infrastrukture za kreiranje, izradu i distribuciju live-patch-ova za Linux kernel. Live-patch-ovi omogu\u0107uju primjenu ispravki na Linux kernelu u stvarnom vremenu, bez ponovnog pokretanja i zaustavljanja sustava. Kod projekta napisan je na jeziku Rust i distribuira se pod licencom Apache 2.0. <\/p>\n

Live-patch-ovi za ispravljanje ranjivosti pru\u017eaju za svoje distribucije kompanije kao \u0161to su Red Hat, Oracle, Canonical i SUSE, ali im je otvorena samo niskonivo alata za rad s patch-ovima, dok se sami patch-ovi formiraju iza zatvorenih vrata. Distribucije Gentoo i Debian poku\u0161avale su razvijati otvorene projekte elivepatch i linux-livepatching, ali je prvi ve\u0107 6 godina napu\u0161ten, dok je drugi zako\u010dio u fazi izrade testnog prototipa. <\/p>\n

TuxTape je usmjeren na organiziranje rada vlastitog sustava za izradu i distribuciju live-patch-ova, neovisnog o vanjskim dobavlja\u010dima i prilagodljivog za sve Linux jezgre, a ne samo za pakete s kernelom odre\u0111enih distribucija. TuxTape mo\u017ee kreirati live-patch-ove kompatibilne s alatom kpatch, koji je razvila kompanija Red Hat (pored kpatch-a postoje sli\u010dni alati: kGraft od SUSE, Ksplice od Oraclea i univerzalni livepatch). Patch-ovi se formiraju u obliku u\u010ditavih modula jezgre, koji zamjenjuju funkcije u jezgri, koriste\u0107i podsustav ftrace za preusmjeravanje na nove funkcije uklju\u010dene u modul.

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

TuxTape mo\u017ee pratiti informacije o ispravljanju ranjivosti u Linux kernelu, objavljene na mailing listi linux-cve-announce i u Git repozitoriju, rangirati ranjivosti po stepenu opasnosti, utvrditi primjenjivost na odr\u017eavane jezgre Linux i generirati live-patch-ove na temelju uobi\u010dajenih patch-ova za LTS grane jezgre. Primjenjivost izvornih patch-ova procjenjuje se profiliranjem izgradnji jezgre. Patch-ovi s ranjivostima koje ne utje\u010du na ciljni kernel se ignoriraju. <\/p>\n

TuxTape uklju\u010duje sustav za pra\u0107enje novih ranjivosti u jezgru, graditelja Baze podataka patch-ova i ranjivosti, server<\/a> za pohranu metapodataka, sustav za raspore\u0111ivanje izgradnje jezgre, graditelj jezgre, generator patch-ova, arhivu patch-ova, klijent za primanje patch-ova za krajnje hostove i interaktivno su\u010delje za upravljanje stvaranjem live-patch-ova.

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

Razvoj se trenutno nalazi u fazi eksperimentalnog prototipa. Za po\u010detno testiranje su ponu\u0111eni: tuxtape-cve-parser za analizu informacija o ranjivostima i izgradnju baze podataka s zakrpama; tuxtape-server s implementacijom gRPC su\u010delja za usluge koje generiraju zakrpe; tuxtape-kernel-builder za sastavljanje kernela u zadanom konfiguraciju i formiranje profila sastavljanja; tuxtape-dashboard \u2014 konzolno su\u010delje za recenziranje i stvaranje live-zakrpa na temelju izvornih zakrpa dobivenih iz tuxtape-server.
