Projekt xz hoidlas ilmuvad j\u00e4tkuvalt muudatused, mille on teinud tagauste autor kaitsemehhanismide blokeerimiseks. CMakeLists.txt kompileerimisstsenaariumis tuvastati muudatus, mis ei lubanud kasutada xz rakenduse isoleerimise mehhanismi Landlocki, kuigi see oli s\u00fcsteemis toetatud. C keeles kirjutatud koodis, mis kontrollib Landlocki s\u00fcsteemikutsumise olemasolu, oli tahtlikult lisatud \u00fcleliigne punkt, mis takistas Landlocki olemasolu kontrollimist mis tahes tingimustel. <\/p>\n

Kohandamine lisati Jia Tan 26. veebruaril, et rakendada laienenud Landlocki toe kontrolli. Varem tehti Landlocki toe j\u00e4reldus ainult faili «linux\/landlock.h» olemasolu p\u00f5hjal, kuid muudatuses lisati C keeles kirjutatud test, mis t\u00e4iendavalt kutsub v\u00e4lja prctl kontrollimiseks.
