Ntxiv chav kawm SELinux txoj cai tshiab: bpf, uas tswj hwm nkag tau mus rau Berkeley Pob Ntawv Lim (BPF) thiab tshuaj xyuas cov ntawv thov rau eBPF.

Lub moj khaum suav nrog SELinux cov ntawv qhia, tsom rau kev siv nrog cov ntim sib cais thiab tso cai ntau rau cov kev pabcuam uas khiav hauv cov thawv los tuav lub peev txheej system.

Txhawm rau tsim SELinux cov cai rau cov ntim khoom, ib qho tshiab Udic nqi hluav taws xob, uas tso cai, coj mus rau hauv tus account cov yam ntxwv ntawm lub thawv tshwj xeeb, muab kev nkag mus tsuas rau cov kev pab sab nraud uas tsim nyog, xws li cov tsev khaws khoom, khoom siv, thiab kev sib txuas.

Hauv kev sib ntsib classic ntawm Gnome Classic, hloov lub desktop virtual hloov. Lub widget hloov ntawm desktops yog tam sim no nyob rau sab xis ntawm lub vaj huam sib luag hauv qab thiab yog tsim los ua ib txoj kab txaij nrog desktop duab me me (kom hloov mus rau lwm lub desktop, tsuas yog nyem rau ntawm tus ntiv tes xoo uas qhia nws cov ntsiab lus).

Cov pob khoom ntxiv nrog GCC 9, LLVM 8.0.1, Xeb 1.37 thiab Mus 1.12.8 mus rau lub software sau.

Qhov SystemTap kab qhia lub cuab yeej tau hloov kho rau ceg 4.1, thiab Valgrind nco debugging vam tau hloov kho rau version 3.15.

Lub pob ntawm dnf-utils tau pauv mus rau yum-utils rau kev siv tau (Lub peev xwm los nruab dnf-utils tau khaws cia, tab sis cov pob no yuav cia li hloov los ntawm yum-utils).

DRM cov kab ke ua haujlwm (Tus Thawj Coj Lub Cev Rov Qab Los) thiab cov tsav tsheb muaj duab tsawg (amdgpu, nouveau, i915, mgag200) lawv tau hloov kho rau lub xeev sib haum rau pob hauv Linux 5.1.
