Linux 5.18 kernel kuburitswa

Mushure memwedzi miviri yebudiriro, Linus Torvalds akapa kuburitswa kweLinux kernel 5.18. Pakati peshanduko dzinonyanya kukosha: kucheneswa kukuru kwekushanda kwechinyakare kwakaitwa, iyo Reiserfs FS yakanzi haichashandi, mushandisi maitiro ekutsvaga zviitiko akaiswa, kutsigirwa kweiyo nzira yekuvharira Intel IBT exploits yakawedzerwa, buffer mafashama yekuona modhi yakagoneswa. uchishandisa memcpy () basa, nzira yekutevera fprobe basa rekufona yakawedzerwa, Kuita kwemugadziri webasa pa AMD Zen CPUs kwakagadziridzwa, mutyairi wekutonga Intel CPU mashandiro (SDS) akaverengerwa, mamwe mapeche akabatanidzwa. nokuda kwekugadzirisa mafaira emusoro, uye kushandiswa kweC11 chiyero kwakagamuchirwa.

Iyo vhezheni itsva inosanganisira 16206 zvigadziriso kubva kune 2127 vagadziri (mukuburitswa kwekupedzisira paive ne14203 zvigadziriso kubva kune 1995 vanogadzira), saizi yechigamba ndeye 108 MB (shanduko dzakakanganisa 14235 mafaera, 1340982 mitsetse yekodhi yakawedzerwa, 593836 mitsara). Inenge 44% yeshanduko dzese dzakaunzwa mu5.18 dzine chekuita nevatyairi vemidziyo, ingangoita 16% yeshanduko ine chekuita nekuvandudza kodhi yakanangana nehardware architecture, 11% ine chekuita netiweki stack, 3% ine hukama nemafaira masisitimu, uye 3% zvine hukama nemukati kernel subsystems.

Makiyi matsva mu kernel 5.18:

  • Disk Subsystem, I/O uye File Systems
    • Iyo Btrfs faira sisitimu yakawedzera tsigiro yekutumira yakadzvanywa data paunenge uchiita kutumira uye kugamuchira mashandiro. Pakutanga, kana uchishandisa kutumira / kugamuchira, rutivi rwekutumira rwakadzikisa data rakachengetwa mufomu yakamanikidzwa, uye rutivi rwakagamuchira rwakaidzokorora zvakare isati yanyora. Muiyo 5.18 kernel, mushandisi-nzvimbo yekushandisa achishandisa kutumira/kugamuchira mafoni akapihwa kugona kufambisa data rakamanikidzwa pasina kurongedzazve. Kuita uku kunoitwa nekuda kweiyo ioctl mashandiro matsva BTRFS_IOC_ENCODED_READ uye BTRFS_IOC_ENCODED_WRITE, ayo anotendera iwe kuverenga nekunyora zvakananga ruzivo kusvika kumazinga.

      Mukuwedzera, Btrfs inovandudza fsync performance. Yakawedzera kugona kudonhedza uye kuita reflink (cloning faira metadata nekugadzira chinongedzo kune iripo data pasina kunyatsoikopa) kune yese chengetedzo, isina kuganhurirwa kumapoinzi.

    • Mune Yakananga I / O modhi, zvinokwanisika kuwana mafaera akavharidzirwa kana fscrypt inoshandisa inline encryption, umo encryption uye decryption mashandiro anoitwa nedhiraivha controller kwete kernel. Nenguva dzose kernel encryption, kuwana mafaera akavharidzirwa uchishandisa Direct I/O hazvisati zvaita, sezvo mafaera anowanikwa nekupfuura nzira yekubhuroka mukernel.
    • Sevha yeNFS inosanganisira tsigiro yeNFSv3 protocol nekukasira, iyo zvino isingade kugoneswa kwakasiyana uye inowanikwa kana NFS ichigoneswa kazhinji. NFSv3 inoonekwa seyakanyanya uye inogara ichitsigirwa shanduro yeNFS, uye tsigiro yeNFSv2 inogona kumiswa mune ramangwana. Kubudirira kwekuverenga dhairekitori zvirimo kwakagadziridzwa zvakanyanya.
    • Iyo ReiserFS faira system yakaderedzwa uye inotarisirwa kubviswa muna 2025. Kudzikisira ReiserFS kunoderedza kuedza kunodiwa kuchengetedza faira system-wide shanduko ine chekuita nerutsigiro rweiyo API nyowani yekuisa, iomap, uye tomes.
