I-Linus Torvalds ityhila ukumiliselwa kwe Inguqulelo entsha yekernel Linux 5.8 kwaye kwesi sitolimende sitsha phakathi kweenguqu eziphawuleka kakhulu yiyo Umtshini wokujonga imeko weKCSAN, isixhobo sendalo iphela sokuthumela izaziso kwindawo yomsebenzisi, Inkxaso yezixhobo zekhompyuter iindlela zokhuselo eziphambili ze-ARM64, inkxaso yeprosesa yaseRussia yeBaikal-T1 Ukukwazi ukwahlula ngokwahlukeneyo iimeko zenkqubo, ukuphunyezwa kweendlela zokhuselo lweShadow ye-ARM64 Call Stack kunye neBTI.
Le nguqulo intsha inkozo yaba lelona likhulu ngokwexabiso lesixa sotshintsho Zonke ii-nuclei kubomi beprojekthi. Kwangelo xesha, utshintsho aluhambelani nayo nayiphi na inkqubo esezantsi, kodwa zigubungela iindawo ezahlukeneyo zekernel kwaye ikakhulu zihambelana nokulungiswa kwangaphakathi nokucoca.
Iimpawu ezintsha eziphambili zeLinux 5.8
Kule nguqulo intsha yeLinux Kernel 5.8 Ukutshixa kubonelelwa ngokulayisha iimodyuli zekernel ezinamacandelo anekhowudi, apho iibits ezivumela ukwenziwa kunye nokubhala kusetwa ngaxeshanye.
Ngoku kunokwenzeka ukuba wenze iimeko ezahlukeneyo zenkqubo, ukuvumela iinkqubo ezininzi zokufaka amanqaku, inyuswe ngeendlela ezahlukeneyo, kodwa ibonisa indawo efanayo ye-pid.
Yeqonga I-ARM64, inkxaso yenkqubo yeShadow-Call Stack iyenziwa, ebonelelwe ngumhlanganisi we Clang ukukhusela ekubhaleni ngaphezulu idilesi yokubuyisa yomsebenzi kwimeko yokugcwala kwempazamo kwisitaki.
ngaphandle koko Inkxaso yeARMv8.5-BTI imiyalelo yongezwa (Isalathiso esijolise kwiSebe) ukukhusela ukwenziwa kweeseti zemiyalelo engafanelekanga ukuba ibe lisebe.
Ukongezwa kwenkxaso yehardware yokubethela kwi-Intanethi kwezixhobo zebhloko, apho izixhobo ezisemgceni zokubethela ezakhelwe ngokubanzi kwi-drive zinokubekwa ngokufanelekileyo phakathi kwememori yenkqubo kunye nediski, ukwenza ukubethela okucacileyo kunye nokuseta ngokusekwe kumaqhosha kunye ne-encryption algorithm echazwe yikernel.
Kule nguqulo intsha Iingcebiso malunga nokusetyenziswa kwesigama esibandakanyayo zibandakanyiwe eyamkelwe kuxwebhu oluchaza imigaqo yokufaka iikhowudi.
Ngaphezu koko Isixhobo esitsha sokulungisa ingxaki seKCSAN sibonisiwe (IKernel Concurrency Sanitizer), eyilelwe ukuba ichonge ngamandla imeko yeembaleki ngaphakathi kernel. Eyona nto kugxilwe kuyo kuphuhliso lwe-KCSAN kukuthintela okungalunganga, ukungabinakho ukusebenza, kunye nokulula kokusebenzisa.
Olunye utshintsho olubalulekileyo kukuba se yongeze umqhubi omtsha we-dm-ebs kwiMephu yeMephu, enokusetyenziselwa ukulinganisa ubungakanani bebhloko encinci (umzekelo, ukulinganisa amacandelo angama-512-byte kwiimoto ezinobungakanani becandelo le-4K).
Ii-Btrf ziphucule ukuphathwa kwemisebenzi yokufunda kwimowudi ethe ngqo. Ekunyukeni, ukukhangela okukhawulezayo kwezikhombisi ezisusiweyo kunye nee-subkeys zashiywa ngaphandle komzali.
I-Ext4 iphucule ukuphatha impazamo ye-ENOSPC xa kusetyenziswa imultithreading. I-Xattr yongeza inkxaso kwi-gnu. Isithuba segama esisetyenziswe yiGNU Hurd.
ukuba I-Ext4 kunye ne-XFS, inkxaso yokusebenza kwe-DAX ifakiwe (ukufikelela ngokuthe ngqo kwiinkqubo zefayile ngokudlula kwindawo yokugcina iphepha ngaphandle kokusebenzisa inqanaba lesixhobo sokutshixa) ngokunxulumene neefayile ezizodwa kunye nezikhombisi.
Ukongeza, inkxaso yongezwa kwikernel kunye nokusetyenziswa kwe-ethtool ukuvavanya intambo yenethiwekhi edibeneyo kunye nokuziqonda ngokwakho kwezixhobo zenethiwekhi.
Ngexesha Isitaki se-IPv6 songeza inkxaso kwi-algorithm ye-MPLS (Multiprotocol Label switching) ukuhambisa iipakethi kusetyenziswa iilebhile zeprotocol yokutshintsha (ye-IPv4, i-MPLS yayixhaswa ngaphambili).
Gqibela kwizixhobo ezikwinguqulelo entsha sinokufumana ukuba:
- Umqhubi we-DRM kwikhadi levidiyo le-Intel i915 lwenziwa ngokusisiseko
- Inkxaso yeetshipsi ze-Intel Tiger Lake (GEN12)
- Umqhubi we-amdgpu wongeza inkxaso kwifomathi ye-pP16 ye-pixel kwaye asebenzise amandla okusebenza kunye ne-encrypted buffers kwimemori yevidiyo.
- Inkxaso ye-AMD Zen kunye ne-Zen2 iprosesa yamandla ombane kunye ne-AMD Ryzen 4000 Renoir sensor sensors.
- Yongeze inkxaso yefomathi yokuguqula i-NVIDIA kumqhubi weNouveau.
- Umqhubi weMSM (Qualcomm) wongeza inkxaso kwiAdreno A405, A640 kunye neA650 GPUs.
- Yongeza isikhokelo sangaphakathi sokulawula izixhobo ze-DRM (uMlawuli oNikelayo ngokuthe ngqo).
- Yongeze inkxaso yeXiaomi Redmi Qaphela i-7 kunye nee-smartphones ze-Samsung Galaxy S2, kunye nee-Elm / Hana Chromebook.
- Abaqhubi abongezelelweyo beepaneli zeLCD: ASUS TM5P5 NT35596, Starry KR070PE2T, Leadtek LTK050H3146W, Visionox rm69299, Boe tv105wum-nw0.
- Inkxaso eyongeziweyo yeebhodi ze-ARM kunye namaqonga eRenesas "RZ / G1H", Realtek
