Emva kweenyanga ezimbini zophuhliso, ILinus Torvalds ibhengeze ukukhutshwa kweLinux kernel 5.12, Inguqulelo apho olona tshintsho lubalulekileyo lubandakanya ukuxhotyiswa kwezixhobo zebhlokhi ecandekileyo kwii-Btrfs, ukukwazi ukwenza imephu ii-ID zomsebenzisi ukwenza iifayile, inkqubo yokulungisa ingxaki ye-KFENCE yokufumana iimpazamo xa usebenza ngememori, phakathi kwabanye.
Inguqulelo entsha ifumene izilungiso eziyi-14170 ezivela kubaphuhlisi baka-1946, Ubungakanani bepatch ngu-38MB (utshintsho lweefayile ezichaphazelekayo 12102 (12090), longezwe 538599 (868025) imigca yekhowudi, isuse imigca engama-333377 (261456)).
Iimpawu ezintsha eziphambili zeLinux 5.12
Isakhono sokumakisha ii-ID zomsebenzisi zeenkqubo zeefayile ezixhonyiweyo senziwe. Imephu yile iyahambelana neFS FAT, ext4 kunye neXFS, apho ukusebenza okucetywayo kwenza kube lula ukuba kwabelwane ngeefayile phakathi kwabasebenzisi abohlukeneyo kunye nakwiikhompyuter ezahlukeneyo, kubandakanya imephu eza kusetyenziswa kwinkqubo yolawulo lwasekhaya olunesistim.
Enye into enqabileyo kukuba inkqubo yefayile I-Btrfs yongeza inkxaso yokuqala yezixhobo zebhloko ebekiweyo. Kwimowudi yokufunda kuphela, inkxaso ibonelelwa ngeebhloko kunye nemethadatha kunye nedatha encinci kunelinye iphepha (iphepha elingaphantsi).
Kuyacaciswa ukuba Amandla okwakha i-kernel kunye ne-Clang compiler yaphunyezwa kubandakanya ukuXhobisa ukuXhobisa ixesha (LTO). Umzekelo, nge-LTO, ukuthunyelwa emgceni kunokwenzeka kwimisebenzi evela kwezinye iifayile, ikhowudi engasetyenziswanga ayifakwanga kwifayile ephumezekayo, uhlobo lokujonga kunye nokwenza ngokubanzi kwenziwa kwinqanaba leprojekthi lilonke. Inkxaso ye-LTO okwangoku inikwe umda kwi-x86 kunye ne-ARM64 yoyilo.
Kwakhona wongeze umqhubi we-nvmem ukufumana idatha kwiindawo zememori ezigcinwe yi-firmware ezingafikeleleki ngokuthe ngqo kwiLinux (umzekelo, inkumbulo ye-EEPROM ifikeleleka ngokwasemzimbeni kuphela kwi-firmware okanye idatha efumaneka kuphela kwinqanaba lokuqala lokulayisha).
Kwelinye icala, kuyacaciswa ukuba Inkqubo yokukhusela i-KFence yongezwa (Kernel Electric Fence), efumanisa iimpazamo xa usebenza ngememori, njengokugcwala kwempazamo kunye nokufikelela emva kokukhulula inkumbulo. Ngokungafaniyo nendlela yokulungisa ingxaki ye-KASAN, inkqubo esezantsi I-KFence yahlulahlulwe ngesantya esiphezulu kunye neendleko eziphantsi kwentloko, ekuvumela ukuba ubone iimpazamo zememori ezibonakala kuphela kwiinkqubo ezisebenzayo okanye ngexesha lokusebenza kwexesha elide.
Inkqubo yokuLinganiswa kweNdawo yokuGcina ingqibelelo (IMA), egcina isiseko sedatha sokungqinisisa ukuthembeka kweefayile kunye nemethadatha ehambelana nayo, ngoku inesakhono sokuqinisekisa ukuthembeka kweenkcukacha zekernel, umzekelo ukulandelela utshintsho kwimithetho ye-SELinux.
Isiphathamandla I-KVM ngoku inako ukubamba i-Xen hypercalls kwaye ubathumele kummeli wesithuba somsebenzisi.
Yongeze amandla okusebenzisa iLinux njengendawo yengcambu yeHyper-V hypervisor njengoko inofikelelo ngqo kwizixhobo kwaye isetyenziselwa ukuqhuba iinkqubo zeendwendwe (ezifanayo neDom0 kwiXen). Kude kube ngoku, iHyper-V (iMicrosoft Hypervisor) ixhasa kuphela iLinux kwimeko yeendwendwe, kodwa ihypervisor ngokwayo ilawulwa kwindawo esekwe kwiWindows.
Umlawuli i-amdgpu isebenzisa amandla okuba ngaphezulu (Ngaphezulu ukuqhuba) tAmakhadi asekwe eSienna Cichlid GPU (UNavi 22, uRadeon RX 6xxx).
Umlawuli I915 ye-Intel Graphics isebenzisa i915.mitigations parameter ukukhubaza ukwahlulwa kunye neendlela zokuzikhusela ngenjongo yokusebenza okungcono. Iichips eziqala nge I-Tiger Ichibi, i-VRR yendlela ebandakanyiweyo (Ixabiso eliguqukayo lokuhlaziya), ekuvumela ukuba uguqule ngokufanelekileyo inqanaba lokuhlaziya ukubek'esweni ukuze kuqinisekiswe ukuguda nokungabikho kwekhefu ngexesha lemidlalo. Kubandakanya inkxaso yeTekhnoloji yoMbala ye-Intel yokuCacisa ukuphucula umbala ngokuchanekileyo.
Umlawuli INouveau Yongeza iNkxaso yokuQala yeNVIDIA GPUs ngokusekwe kwi-Architecture ye-GA100 (Ampere). Umqhubi we-msm wongeza inkxaso kwi-Adreno 508, 509, kunye ne-512 GPUs ezisetyenziswa kwi-SDM (Snapdragon) 630, 636, kunye neetshipsi ezingama-660.
Inkxaso eyongeziweyo yeSandi BlasterX AE-5 Plus, Lexicon I-ONIX FW810s, kunye noovulindlela be-DJM-750 amakhadi esandi. Inkxaso eyongeziweyo ye-Intel Alder Lake PCH-P yeaudio subsystem.
Kwakhona, kule nguqulo intsha yeLinux 5.12 Inkxaso yemidlalo yomdlalo weNintendo 64 yenziwe yaseburhulumenteni yenziwe phakathi kuka-1996 no-2003 (iinzame zangaphambili zokungena kweLinux ukuya kwiNintendo 64 zazingaphelelanga kwaye zazinendawo yeVaporware).
Yongezwe Inkxaso yeqonga leLenovo IdeaPad ngesakhono sokulawula umthwalo rhoqo kunye nokukhanyisa kwebhodi yezitshixo. Ikwaxhasa iprofayile ye-ACPI yeqonga le-ThinkPad elinamandla olawulo. Umqhubi ongezelelweyo weLenovo ThinkPad X1 yeCwecwe Gen 2 HID subsystem.
Yongezwe Inkxaso yeebhodi ze-ARM, izixhobo kunye namaqonga: I-PineTab, i-Snapdragon 888 / SM8350, i-Snapdragon MTP, ii-Beacon ezimbini ezifakwe kwiWorks, i-Intel eASIC N5X, iNetgear R8000P, iPlymovent M2M, iBeacon i.MX8M Nano, iNanoPi M4B.
