Compania de asigur\u0103ri GEICO a publicat o versiune preliminar\u0103 a instrumentului TuxTape, care permite desf\u0103\u0219urarea unei infrastructuri proprii pentru crearea, compilarea \u0219i livrarea live-patch-urilor pentru kernelul Linux. Live-patch-urile permit aplicarea corec\u021biilor la kernelul Linux \u00een timp real, f\u0103r\u0103 a restarta sau opri sistemul. Codul proiectului este scris \u00een limbajul Rust \u0219i este distribuit sub licen\u021ba Apache 2.0. <\/p>\n

Live-patch-urile care remediaz\u0103 vulnerabilit\u0103\u021bile sunt furnizate pentru distribu\u021biile lor de c\u0103tre companii precum Red Hat, Oracle, Canonical \u0219i SUSE, \u00eens\u0103 instrumentarul lor de baz\u0103 pentru lucrul cu patch-uri este deschis doar la nivel de baz\u0103, \u00een timp ce patch-urile \u00een sine sunt generate \u00een spatele u\u0219ilor \u00eenchise. Distribu\u021biile Gentoo \u0219i Debian au \u00eencercat s\u0103 dezvolte proiecte deschise elivepatch \u0219i linux-livepatching, dar primul este abandonat de 6 ani, iar al doilea a stagnat \u00een stadiul de dezvoltare a unui prototip de test. <\/p>\n

TuxTape vizeaz\u0103 organizarea func\u021bion\u0103rii unui sistem propriu pentru creare \u0219i livrare de live-patch-uri, independent de furnizorii externi \u0219i adaptabil pentru orice kernel Linux, nu doar pentru pachete cu kernelul unui anumit distribuitor. TuxTape poate genera live-patch-uri compatibile cu instrumentarul kpatch dezvoltat de Red Hat (\u00een afar\u0103 de kpatch exist\u0103 instrumente similare: kGraft de la SUSE, Ksplice de la Oracle \u0219i un livepatch universal). Patch-urile sunt create sub form\u0103 de module desc\u0103rcabile ale kernelului, care \u00eenlocuiesc func\u021biile din kernel, utiliz\u00e2nd subsistemul ftrace pentru a redirec\u021biona c\u0103tre noile func\u021bii incluse \u00een modul.

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

TuxTape poate urm\u0103ri informa\u021biile despre corectarea vulnerabilit\u0103\u021bilor din kernelul Linux, publicate \u00een lista de discu\u021bie linux-cve-announce \u0219i \u00een depozitul Git, poate clasifica vulnerabilit\u0103\u021bile \u00een func\u021bie de gravitate, identifica aplicabilitatea acestora la kernelurile Linux gestionate \u0219i genera live-patch-uri pe baza patch-urilor obi\u0219nuite pentru ramurile LTS ale kernelului. Aplicabilitatea patch-urilor surs\u0103 este evaluat\u0103 prin profilarea compunerilor kernelului. Patch-urile cu vulnerabilit\u0103\u021bi care nu afecteaz\u0103 kernelul \u021bint\u0103 sunt ignorate. <\/p>\n

TuxTape include un sistem pentru urm\u0103rirea noilor vulnerabilit\u0103\u021bi \u00een kernel, un constructor de baze de date pentru patch-uri \u0219i vulnerabilit\u0103\u021bi, serverul<\/a> pentru stocarea metadatelor, un sistem de gestionare a compunerii kernelului, un compilator de kernel, un generator de patch-uri, un arhivator de patch-uri, un client pentru ob\u021binerea patch-urilor pentru gazdele finale \u0219i o interfa\u021b\u0103 interactiv\u0103 pentru gestionarea gener\u0103rii live-patch-urilor.

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

Dezvoltarea se afl\u0103 \u00een stadiul prototipului experimental. Pentru testarea ini\u021bial\u0103 au fost propuse: tuxtape-cve-parser pentru analiza informa\u021biilor despre vulnerabilit\u0103\u021bi \u0219i construirea unei baze de date cu patch-uri; tuxtape-server cu implementarea interfe\u021bei gRPC pentru serviciile care genereaz\u0103 patch-uri; tuxtape-kernel-builder pentru compilarea nucleului \u00een configura\u021bia specificat\u0103 \u0219i generarea profilului de compilare; tuxtape-dashboard \u2014 o interfa\u021b\u0103 de consol\u0103 pentru revizuirea \u0219i crearea de patch-uri live pe baza patch-urilor surs\u0103 ob\u021binute din tuxtape-server.
