Linuxi tuumse koosseisus rakendatud tekstikonsoli on eemaldatud kood<\/a><\/noindex>, mis v\u00f5imaldab teksti tagasi kerida (CONFIG_VGACON_SOFT_SCROLLBACK). Kood eemaldati, kuna leiti vigu, mille parandamiseks ei olnud kedagi, kes hoolitseks vgacon arenduse eest.<\/p>\n

Suvel avastati vgaconis on k\u00f5rvaldatud<\/a><\/noindex> turvaauk (CVE-2020-14331), mis v\u00f5ib p\u00f5hjustada puhver\u00fclese \u00fclevoolu, kuna puhverkerimise ajal ei kontrollitud piisavalt m\u00e4lu k\u00e4ttesaadavust. Turvaauk t\u00f5mbas arendajate t\u00e4helepanu, kes korraldasid vgaconi koodi fuzzing-testimist syzbot<\/a><\/noindex>.<\/p>\n

Lisa kontrollid avastasid veel m\u00f5ned sarnased probleemid vgaconi koodis, samuti probleemid puhverkerimise programmialases teostuses fbcon draiveris. Kahjuks on probleemne kood juba ammu hoolduseta, eeldatavasti kuna arendajad on l\u00e4inud \u00fcle graafilistele konsoolidele ning tekstikonsolid on j\u00e4\u00e4mas tahaplaanile (kuigi inimesed kasutavad j\u00e4tkuvalt vgacon ja fbcon konsoole, ei ole need juba aastaid olnud tuuma peamine liides ja sellised laiendatud funktsioonid nagu draiverisse integreeritud kerimine (Shift+PageUp\/PageDown) pole t\u00f5en\u00e4oliselt enam n\u00f5utud). <\/p>\n

Seet\u00f5ttu otsustas Linus Torvalds, et ei p\u00fc\u00fca hooldada n\u00f5udluseta koodi, vaid lihtsalt eemaldada selle. Kui leitakse kasutajaid, kellele see funktsionaalsus on vajalik, siis tugikood konsooli kerimise toetamiseks tagastatakse tuuma, kui leitakse hooldaja, kes on valmis seda enda hoole alla v\u00f5tma.<\/p>\n
