Linus Torvalds yakafumura kuvhurwa kwe iyo nyowani vhezheni yekernel Linux 5.8 uye muchikamu ichi chitsva pakati pekuchinja kwakakurumbira they are the KCSAN nhangemutange yekumisikidza detector, yepasirese mashandiro ekutumira Notices kune mushandisi nzvimbo, rutsigiro rwe Hardware rwekunyorera pamhepo, epamberi nzira dzekudzivirira dzeARM64, rutsigiro rweRussia Baikal-T1 processor, iyo kugona kwega kupatsanura maitiro enzira, kuitiswa kweiyo Shadow dziviriro nzira dzeARM64 Call Stack uye BTI.
Iyi vhezheni itsva Kernel yakava yakakura kwazvo maererano nehuwandu hwekuchinja dzese nuclei mukati mehupenyu hweprojekti. Panguva imwecheteyo, shanduko hadzibatanidzwe nechero hurongwa, asi inovhara zvikamu zvakasiyana zveiyo uye inowanzoenderana nekugadziriswa kwemukati nekuchenesa.
Main nyowani maficha eLinux 5.8
Mune ino vhezheni itsva yeLinux Kernel 5.8 kukiya kunopihwa kurodha kernel module dzine zvikamu zvine kodhi, mune mabheti anotendera kuisirwa uye kunyora panguva imwe chete.
Iye zvino zvinokwanisika kugadzira akasiyana maitiro maitiro, ichibvumira akawanda maitiro kukwirisa mapoinzi, akaiswa nesarudzo dzakasiyana, asi achiratidza yakafanana pid namespace.
Yeplatform ARM64, rutsigiro rweShadow-Call Stack michina inoitwa, yakapihwa naClang compiler kudzivirira kubva pakunyora kero yekudzoka yebasa kana chiitiko chebhavhu rakafashukira mudura.
kunze kwaizvozvo tsigiro yeARMv8.5-BTI mirairo yakawedzerwawo (Bazi Target Chiratidziro) kuchengetedza kuisirwa kwemaiseti seti iyo isingafanire bazi.
Wakawedzera rutsigiro rwe Hardware rwekunyorera pamhepo pamabhuroko emidziyo, iyo inline encryption zvishandiso iyo inowanzo yakavakirwa mudhiraivha inogona kuiswa zvine mutsindo pakati peiyo system memory uye diski, ichiita pachena kujekesa uye kududzira kunobva pane kernel-yakatsanangurwa encryption algorithm nemakiyi.
Zvakare, mune iyi vhezheni itsva Kurudziro pakushandiswa kweshoko remazwi rakabatanidzwa izvo zvinogamuchirwa mugwaro rinotsanangura iyo mitemo yekukodha.
Zvakare, zvakare nyowani KCSAN chishandiso chekugadzirisa chakaratidzwa (Kernel Concurrency Sanitizer), yakagadzirirwa kuratidza zvine mutsindo mamiriro emujaho mukati meiyo kernel. Chinonyanya kukosheswa mukuvandudza kweKCSAN ndeyekudzivirira kwakanaka kwenhema, kusagadzikana, uye nyore kushandisa.
Imwe shanduko yakakosha ndeyekuti se yawedzera nyowani dm-ebs driver kuMuchina Mapper, iyo inogona kushandiswa kuteedzera diki inonzwisisika block saizi (semuenzaniso, kutevedzera 512-byte sectors pane anotyaira ane 4K chikamu chikamu).
Btrfs yakavandudza mashandiro ekuverenga mashandiro munzira yakatwasuka. Pakukwidza, kumhanyisa kutsvaga kwekubvisa madhairekitori uye subkeys kwakasiiwa pasina mubereki.
Ext4 yakavandudza ENOSPC kukanganisa kubata apo multithreading inoshandiswa. Xattr inowedzera kutsigira gnu. * Namespace inoshandiswa neGNU Hurd.
Para Ext4 uye XFS, rutsigiro rwemabasa eDAX rwunosanganisirwa (yakanangana nekuwana mafaera masystem usingapfuure neiyo peji cache usingashandisi ichivharira nhanho yedhijitari) inoenderana neayo mafaera uye madhairekitori.
Uye zvakare, rutsigiro rwakawedzerwa kune iyo kernel uye ethtool utility kuyedza iyo yakabatana network tambo uye yekuzviongorora-wega kwema network zvigadzirwa.
Nguva yeiyo IPv6 stack inowedzera rutsigiro rweMPLS algorithm (Multiprotocol Label switching) kuendesa mapaketi uchishandisa multiprotocol label switching (ye IPv4, MPLS yaimbotsigirwa).
Finalmente yeiyo Hardware mune iyi vhezheni itsva tinogona kuwana kuti:
- DRM mutyairi weIntel i915 kadhi yevhidhiyo inogoneswa nekutadza
- Tsigiro yeIntel Tiger Lake (GEN12) machipisi
- Iyo amdgpu mutyairi inowedzera rutsigiro rweiyo FP16 pixel fomati uye inoshandisa kugona kushanda neakavharidzirwa mabhauda mune vhidhiyo ndangariro.
- Tsigiro ye AMD Zen uye Zen2 processor magetsi maseru uye AMD Ryzen 4000 Renoir tembiricha sensors.
- Wakawedzera rutsigiro rweNVIDIA modifier fomati kune mutyairi weNouveau.
- MSM (Qualcomm) mutyairi anowedzera rutsigiro rweAdreno A405, A640 uye A650 GPUs.
- Yakawedzera chimiro chemukati chekugadzirisa DRM (Direct Rendering Manager) zviwanikwa.
- Yakawedzera rutsigiro rweXiaomi Redmi Cherechedzo 7 uye Samsung Galaxy S2 mafoni, pamwe neElm / Hana Chromebook.
- Kuwedzera madhiraivha eLCD mapaneru: ASUS TM5P5 NT35596, Starry KR070PE2T, Leadtek LTK050H3146W, Visionox rm69299, Boe tv105wum-nw0.
- Wakawedzera rutsigiro rweARM mabhodhi uye mapuratifomu Renesas "RZ / G1H", Realtek
- Wakawedzera rutsigiro rweMIPS Loongson-2K processor
