Warbixinta Horumarka ee FreeBSD Q2019 XNUMX

la daabacay warbixin ku saabsan horumarinta mashruuca FreeBSD laga bilaabo Abriil ilaa Juun 2019. Waxaa ka mid ah isbeddellada waxaan ka xusi karnaa:

• Arrimaha guud iyo nidaamka
  • Kooxda Core waxay go'aansatey in ay dhisto koox shaqo si ay u sahamiso suurtagalnimada in laga raro koodhka isha laga soo guuriyo nidaamka xakamaynta isha-hoosaadka loona wareejiyo nidaamka Git ee baahsan.
  • Waxaa la sameeyay tijaabada fuzzka ee kernel-ka FreeBSD iyadoo la adeegsanayo nidaamka syzkaller waxaana la saxay khaladaad badan oo la aqoonsaday. Waxaa lagu daray lakab loogu talagalay tijaabinta qallafsan ee maktabadaha si ay ula jaanqaadaan jawiga 32-bit ee nidaamyada leh kernel 64-bit ah. Awoodda lagu socodsiiyo syzkaller ee mashiinnada farsamada ee ku saleysan bhyve ayaa la hirgeliyay. Marxaladda xigta, waxaa la qorsheeyey in la balaadhiyo daboolida tijaabada wicitaanka nidaamka, isticmaal nadiifiyaha LLVM si aad u hubiso kernel-ka, adeegso netdump si aad u badbaadiso qashinka kernel-ka inta lagu jiro shilalka inta lagu jiro tijaabada jahawareerka, iwm.
  • Shaqada ayaa ka bilaabatay cusboonaysiinta hirgelinta zlib ee heerka kernel-ka. Helitaanka kernel-ka zlib code-ka, hagaha wax-ka-qabashada/zlib waxaa loo beddelay sys/contrib/zlib, iyo faylka madaxa ee crc.h ayaa sidoo kale loo beddelay si looga fogaado isku dhaca zlib/crc.h. Nadiifiyey koodka dhaxalka ee ku tiirsan zlib iyo sicir-barar. Marka xigta, waxaa la qorsheeyay in la bixiyo awoodda lagu dhisayo kernel-ka isla mar ahaantaana la jirkii hore iyo kan cusub ee zlib si tartiib tartiib ah loogu wareejiyo nooca cusub ee shaqooyinka isticmaala cadaadiska;
