Mushure memwedzi miviri yekuvandudza, Linus Torvalds yakazivisa kuburitswa kweLinux kernel 5.19, muchiziviso, Linus akataura kuti inotevera kernel vhezheni inogona kunge iri 6.0, sezvo kune shanduro dzakakwana pabazi re 5.x kushandura nhamba yekutanga munhamba yeshanduro. Shanduko yenhamba inoitwa nekuda kwezvikonzero zvekunaka uye inhanho yepamutemo inoderedza kusagadzikana kunokonzerwa nekuunganidzwa kwenhamba huru munhevedzano.
linus futi wakataura kuti wakashandisa Apple laptop yakavakirwa paArM64 architecture (Apple Silicon) ine Linux nharaunda yakavakirwa pakugoverwa kweAsahi Linux kugadzira kutanga . Haisiyo nzvimbo huru yekushanda yaLinus, asi akashandisa chikuva kuyedza kukodzera kwayo kwekernel basa uye kuve nechokwadi chekuti anogona kuvaka kernel inovaka panhunzi aine isingaremi laptop padyo.
Main nyowani maficha eLinux 5.19
Mune iyi vhezheni itsva inoratidzwa kwakakosha optimizations yakaitwa kune exFAT mutyairi, Zvinechekuita nekuona kupukuta panguva imwe chete yeboka rezvikamu zvine 'dirsync' modhi inoshanda, pane inotevedzana chikamu-ne-chikamu kupukuta. Nekudzikisa huwandu hwezvikumbiro zveblock mushure mekugadzirisa, kuita kwekugadzira nhamba huru yedhairekitori pane SD kadhi yakawedzera neinopfuura 73-85%, zvichienderana nehukuru hwesumbu.
Iyo yekutanga kugadzirisa update ye ntfs3 mutyairi iyo inosanganisirwa mu kernel iyi. Kubva pakaiswa ntfs3 mu kernel 5.15 muna Gumiguru gore rapfuura, mutyairi haana kuvandudzwa uye kutaurirana nevagadziri kwakarasika, asi ikozvino vagadziri vakatangazve kutumira shanduko. Iwo mapeche akarongwa anogadzirisa tsikidzi dzinokonzera kudonha kwendangariro uye kuputsika, kugadzirisa matambudziko nekumhanya xfstests, chenesa kodhi isina kushandiswa, uye gadzirisa typos.
Mukuwedzera kune izvi, zvinoratidzwa zvakare kuti yakabviswa kodhi kutsigira a.out inogoneka faira fomati, iyo yakabviswa muvhezheni 5.1. Iyo a.out fomati haisati yashandiswa paLinux masisitimu kwenguva yakareba, uye maturusi emazuva ano haatsigire kugadzira a.out mafaera mukumisikidzwa kweLinux. Iyo a.out file uploader inogona kuitwa zvachose munzvimbo yemushandisi.
Zvekuvakwa RISC-V, tsigiro inopihwa yekumhanyisa 32-bit eecutable mafaera pane 64-bit masisitimu. bits, nzira yekusunga hunhu hunogumira kumapeji ekurangarira (semuenzaniso, kudzima caching) inowedzerwa, uye kexec_file_load () basa rinoitwa.
Sisitimu EFI inoshandisa kugona kutumira zvakavanzika ruzivo kune masisitimu vaenzi pasina kuzvizivisa kune iyo host system. Iyo data inopihwa kuburikidza nechengetedzo / coco dhairekitori mune securityfs.
Iyo Lockdown kuchengetedza modhi, iyo inorambidza kupinda kwemidzi kune kernel uye inovharira UEFI Chengetedza Boot yekupfuura nzira, yakagadzirisa mukaha waibvumira kuchengetedzwa kupfuudzwa nekushandisa kernel debugger.
Kune rimwe divi, zvinoratidzwa izvo yakawedzera rutsigiro rwe AMD SEV-SNP yekuwedzera (Yakachengeteka Nested Paging), iyo inopa kushanda kwakachengeteka neinested memory peji matafura uye inodzivirira kubva ku "undeSerVed" uye "SEVerity" kurwiswa kwe AMD EPYC processors, iyo inobvumira iyo AMD SEV (Yakachengeteka Encrypted Virtualization) yekuwedzera kuti ipfuure. ) nzira yekudzivirira.
Yakawedzerwa rutsigiro rweIntel TDX michina (Trusted Domain Extensions), iyo inokutendera kuti uvhare kuedza kwevechitatu mapato kuwana iyo encrypted memory yemuchina chaiwo.
Pamusoro pazvo, akaramba achishanda stack kubatanidzwa network zvishandiso zvekutsvaga zvikonzero zvekudonhedza mapaketi (chikonzero makodhi). Chikonzero kodhi inotumirwa panguva yekuburitswa kwendangariro yakabatana nepakiti uye inobvumira mamiriro akadai sekurasa pakiti nekuda kwekukanganisa mukuzadza minda mumusoro, kuona spoofing ne rp_filter sefa, checksum isiriyo, kunze kwendangariro kutorwa. muakaundi. , IPSec XFRM mutemo activation, isiriyo TCP kutevedzana nhamba, nezvimwe.
Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo nezve iyi vhezheni nyowani, iwe unogona kutarisa iyo ruzivo Mune inotevera chinongedzo.
