Google teatas, et programmeerimiskeel Rust on n\u00fc\u00fcd lubatud Androidi platvormi arendamise keelte hulgas. Rust'i kompilaator liideti Androidi l\u00e4htekoodi puusse juba 2019. aastal, kuid selle keele tugi j\u00e4i katsetusj\u00e4rku. \u00dcks esimesi Rust'is loodud komponente, mis plaanitakse Androidisse lisada, on uued rakendused protsessidevahelise suhtluse mehhanismist Binder ja Bluetooth'i protokollist. <\/p>\n

Rust'i kasutuselev\u00f5tt on osa projektist, mille eesm\u00e4rk on tugevdada turvalisust, edendada turvalise programmeerimise praktikaid ja t\u00e4iustada m\u00e4luhaldusprobleemide avastamise efektiivsust Androidis. N\u00e4hakse, et ligikaudu 70% Androidis avastatud ohtlikest haavatavustest tuleneb m\u00e4luhaldusvigadest. Rust'i, mis keskendub m\u00e4luturvalisusele ja pakub automaatset m\u00e4luhaldust, kasutamine v\u00e4hendab ohtu haavatavuste tekkeks, mis on p\u00f5hjustatud m\u00e4luhaldusvigadest, nagu m\u00e4lupiirkondadele juurdep\u00e4\u00e4s p\u00e4rast nende vabastamist ja puhvriv\u00e4\u00e4rtuse \u00fcleastumine. <\/p>\n

Rust tagab m\u00e4lut\u00f6\u00f6 turvalisuse tagamise kompileerimise ajal viidete kontrollimise, objektide omandi j\u00e4lgimise ja objektide eluea (ulatus) arvestamise kaudu ning hindab koodi k\u00e4ivitamise ajal m\u00e4lu juurdep\u00e4\u00e4su \u00f5igsust. Rust pakub ka vahendeid t\u00e4isarvude \u00fclet\u00e4itumise vastu kaitsmiseks, n\u00f5uab muutujate v\u00e4\u00e4rtuste kohustuslikku initsialiseerimist enne kasutamist, haldab t\u00f5husamalt vigu standardses teegis, rakendab immutamatuse (immutable) viiteid ja muutujaid vaikimisi ning pakub tugevat staatilist t\u00fc\u00fcbistamist loogiliste vigade minimeerimiseks. <\/p>\n

Androidis tagab m\u00e4lut\u00f6\u00f6 turvalisuse juba toetatud keeltes Kotlin ja Java, kuid need ei sobi s\u00fcsteemikomponentide arendamiseks k\u00f5rgete kulude t\u00f5ttu. Rust v\u00f5imaldab saavutada j\u00f5udluse, mis on l\u00e4hedane C ja C++ keeltele, muutes selle sobivaks madala taseme platvormide ja riistvaraga suhtlemise komponentide arendamiseks. <\/p>\n

Koodi kaitsmiseks C ja C++ puhul Androidis rakendatakse sandbox-isolatsiooni, staatilist anal\u00fc\u00fcsi ja fuzzing-teste. Sandbox-isolatsiooni v\u00f5imalused on piiratud ja on saavutanud oma v\u00f5imekuse piiri (edasi jagamine protsessidesse ei ole ressursside tarbimise seisukohalt m\u00f5istlik). Sandbox'i rakendamise piirangutena mainitakse suurt t\u00e4iendavat kulu ja m\u00e4lutarbimise kasvu, mis tuleneb uute protsesside genereerimise vajadusest, samuti t\u00e4iendavaid viivitusi, mis on seotud IPC kasutamisega. <\/p>\n

Kuid sandbox ei k\u00f5rvalda koodivigu, vaid v\u00e4hendab ainult riske ja muudab r\u00fcnnaku l\u00e4biviimise keerulisemaks, kuna nende kasutamiseks on vajalik tuvastada mitte ainult \u00fcks, vaid mitu haavatavust. Kooditesti p\u00f5hine meetod on piiratud sellega, et vigade avastamiseks tuleb luua olukord, kus probleem avaldub. K\u00f5ikv\u00f5imalike variantide h\u00f5lmamine ei ole v\u00f5imalik, mist\u00f5ttu j\u00e4\u00e4b palju vigu avastamata. <\/p>\n

Google ei kavatse olemasolevat C\/C++ koodi Rustis \u00fcmber kirjutada, vaid plaanib kasutada seda keelt uue koodi arendamiseks. Rusti kasutamine uue koodi jaoks on m\u00f5ttekas, kuna statistika kohaselt ilmneb enamus vigu uues v\u00f5i hiljuti muudetud koodis. Eelk\u00f5ige tuvastatakse umbes 50% Androidi m\u00e4lut\u00f6\u00f6tluse vigu koodis, mis on kirjutatud alla aasta tagasi.
