Fr\u00e5n leveransen av k\u00e4rnversionen av Linux, som inneh\u00e5ller textkonsolen har koden tagits bort<\/a><\/noindex>, som m\u00f6jligg\u00f6r rullning av text bak\u00e5t (CONFIG_VGACON_SOFT_SCROLLBACK). Koden togs bort p\u00e5 grund av fel, som ingen har kunnat \u00e5tg\u00e4rda p\u00e5 grund av bristen p\u00e5 en underh\u00e5llare som \u00f6vervakar utvecklingen av vgacon.<\/p>\n

Under sommaren uppt\u00e4cktes en har \u00e5tg\u00e4rdats<\/a><\/noindex> s\u00e4kerhetsbrist (CVE-2020-14331) i vgacon, som kan leda till buffert\u00f6verflyttning p\u00e5 grund av avsaknaden av ordentliga kontroller f\u00f6r tillg\u00e4ngligt minne i rullningsbufferten. S\u00e4kerhetsbristen v\u00e4ckte uppm\u00e4rksamhet fr\u00e5n utvecklarna, som organiserade fuzzing-testning av koden f\u00f6r vgacon i syzbot<\/a><\/noindex>.<\/p>\n

. Ytterligare kontroller har avsl\u00f6jat flera liknande problem i koden f\u00f6r vgacon, samt problem i den mjukvaruimplementeringen av rullning i fbcon-drivrutinen. Tyv\u00e4rr har den problematiska koden l\u00e4nge varit utan st\u00f6d, troligen eftersom utvecklarna har \u00f6verg\u00e5tt till att anv\u00e4nda grafiska konsoler och textkonsoler har fallit i gl\u00f6mska (folk forts\u00e4tter att anv\u00e4nda konsoler som vgacon och fbcon, men de har inte varit det prim\u00e4ra gr\u00e4nssnittet f\u00f6r k\u00e4rnan p\u00e5 \u00e5ratal och s\u00e5dana avancerade funktioner som inbyggd rullning i drivrutinen (Shift+PageUp\/PageDown) \u00e4r troligen inte s\u00e5 efterfr\u00e5gade). <\/p>\n

Mot bakgrund av detta har Linus Torvalds beslutat att inte f\u00f6rs\u00f6ka underh\u00e5lla den oanv\u00e4nda koden, utan ist\u00e4llet bara ta bort den. Om det finns anv\u00e4ndare som anser att denna funktionalitet \u00e4r n\u00f6dv\u00e4ndig, kommer koden f\u00f6r att st\u00f6dja rullning i konsolen att \u00e5terf\u00f6ras till k\u00e4rnan s\u00e5 snart en underh\u00e5llare finns tillg\u00e4nglig som kan ta p\u00e5 sig att underh\u00e5lla den.<\/p>\n
