Ukukhishwa kwe-kernel ye-Linux 5.7

Ngemuva kwezinyanga ezimbili zokuthuthuka, uLinus Torvalds kwethulwa ukukhishwa kwe-kernel Linux 5.7. Phakathi kwezinguquko eziphawuleka kakhulu: ukuqaliswa okusha kohlelo lwefayela le-exFAT, imojula ye-bareudp yokudala imigudu ye-UDP, ukuvikelwa okusekelwe ekuqinisekiseni isikhombisi se-ARM64, ikhono lokunamathisela izinhlelo ze-BPF kubaphathi be-LSM, ukuqaliswa okusha kwe-Curve25519, ukuhlukaniswa- umtshina wokukhiya, ukuhambisana kwe-BPF ne-PREEMPT_RT, ukususa umkhawulo kusayizi womugqa wezinhlamvu ezingu-80 kukhodi, kucatshangelwa izinkomba zokushisa ze-CPU kusihleli somsebenzi, ikhono lokusebenzisa i-clone() ukuzalanisa izinqubo kwelinye iqembu, ukuvikelwa ekubhaleni kumemori usebenzisa i-userfaultfd.

Inguqulo entsha ifaka phakathi ukulungiswa okungu-15033 okuvela kubathuthukisi abayi-1961,
usayizi wesichibi - 39 MB (izinguquko zithinte amafayela angu-11590, zengeza imigqa yekhodi engu-570560,
297401 imigqa isusiwe). Cishe u-41% wabo bonke owethulwe ngo-5.7
izinguquko zihlobene nezishayeli zedivayisi, cishe u-16% wezinguquko zinjalo
isimo sengqondo mayelana nokuvuselela ikhodi eqondene nezakhiwo zehadiwe, i-13%
okuhlobene nesitaki senethiwekhi, i-4% kumasistimu wefayela kanye no-4% kuya kwangaphakathi
i-kernel subsystems.

main emisha:

  • I-Disk Subsystem, I/O kanye ne-File Systems
    • Kwengezwe ukuqaliswa okusha komshayeli we-exFAT, yasungulwa ngokusekelwe kusisekelo samanje sekhodi β€œsdfat” (2.x) esakhiwe i-Samsung yama-smartphones ayo e-Android. Umshayeli owengezwe ngaphambilini ku-kernel wayesekelwe kukhodi ye-Samsung yefa (inguqulo 1.2.9) futhi wayecishe abe ngu-10% ngemuva komshayeli omusha ekusebenzeni. Masikhumbule ukuthi ukwengeza ukwesekwa kwe-exFAT ku-kernel kwenzeke ngemuva kweMicrosoft eshicilelwe ukucaciswa komphakathi nokwenza amalungelo obunikazi e-exFAT atholakale ukuze asetshenziswe mahhala ku-Linux.
    • I-Btrfs isebenzisa umyalo omusha we-ioctl() - BTRFS_IOC_SNAP_DESTROY_V2, okuvumela ukuthi ususe isigatshana ngesihlonzi saso.

    • Ku-dm_writecache kwenziwe ikhono lokusula kancane kancane inqolobane ngokusekelwe kupharamitha ye-max_age, ebeka isikhathi sokuphila esiphezulu sebhulokhi.
    • Ku-dm_integrity kwengezwe usekelo lokusebenza "lahla".
    • Ku-null_blk kwengezwe ukusekelwa kokushintshwa kwephutha ukuze kulingise ukwehluleka ngesikhathi sokuhlola.
    • Kwengeziwe ikhono lokuthumela izaziso ze-udev mayelana nezinguquko zikasayizi wedivayisi.
  • Isistimu engaphansi yenethiwekhi
    • I-Netfilter ifakiwe shintsha, isheshisa ngokuphawulekayo ukucutshungulwa kohlu olukhulu lokufanisa (amasethi we-nftables), okudinga ukuhlola inhlanganisela yama-subnet, izimbobo zenethiwekhi, amakheli omthetho kanye namakheli e-MAC.
      Ukuthuthukisa yethulwe kumojula ye-nft_set_pipapo (PIle Packet POlicies), exazulula inkinga yokumatanisa okuqukethwe kwephakethe ngobubanzi besimo senkambu engafanele esetshenziswa emithethweni yokuhlunga, njenge-IP kanye nobubanzi bembobo yenethiwekhi (nft_set_rbtree kanye ne-nft_set_hash baphatha ukufanisa isikhawu nokuboniswa okuqondile kwamanani ). Inguqulo ye-pipapo vectorized kusetshenziswa imiyalelo engu-256-bit AVX2 kusistimu ene-AMD Epyc 7402 processor ibonise ukukhuphuka kokusebenza okungu-420% lapho kudluliswa amarekhodi ayizinkulungwane ezingu-30 okuhlanganisa nezinhlanganisela ze-port-protocol. Ukwenyuka lapho kuqhathaniswa inhlanganisela ye-subnet nenombolo yembobo lapho kudluliswa amarekhodi angu-1000 kube ngu-87% we-IPv4 kanye no-128% we-IPv6.

    • Kwengezwe bareudp module, ekuvumela ukuthi uhlanganise izivumelwano ezihlukahlukene ze-L3, njenge-MPLS, IP ne-NSH, emhubheni we-UDP.
    • Ukuhlanganiswa kwezingxenye ze-MPTCP (MultiPath TCP), ukunwetshwa kwephrothokholi ye-TCP yokuhlela ukusebenza koxhumano lwe-TCP nokulethwa kwamaphakethe ngesikhathi esisodwa emizileni eminingana ngokusebenzisa ukuxhumana kwenethiwekhi okuhlukene okuboshelwe kumakheli e-IP ahlukene, kuqhubekile.
    • Kwengeziwe usekelo lwezindlela zokusheshisa ihadiwe zokuhlanganisa ozimele be-Ethernet ku-802.11 (Wi-Fi).
    • Lapho uhambisa idivayisi isuka endaweni yegama yenethiwekhi iye kwenye, amalungelo okufinyelela nobunikazi bamafayela ahambisanayo kuma-sysfs ayalungiswa.
    • Kwengezwe amandla okusebenzisa ifulegi le-SO_BINDTODEVICE kubasebenzisi abangeyona impande.
    • Ingxenye yesithathu yamapeshi yamukelwe, iguqulela ikhithi yamathuluzi e-ethtool isuka ku-ioctl() iye ekusebenziseni isixhumi esibonakalayo se-netlink. I-interface entsha yenza kube lula ukwengeza izandiso, ithuthukisa ukuphathwa kwamaphutha, ivumela izaziso ukuthi zithunyelwe lapho isimo sishintsha, yenza kube lula ukuxhumana phakathi kwe-kernel nesikhala somsebenzisi, futhi inciphisa inombolo yohlu oluqanjiwe oludinga ukuvumelanisa.
    • Kwengezwe ikhono lokusebenzisa izisheshisi zehadiwe ezikhethekile ukwenza imisebenzi yokulandelela uxhumano.
    • Ku-netfilter kungezwe ihhuku yokuxhuma izigaba zamaphakethe aphumayo (i-egress), ehambisana nehhuku yangaphambilini yamaphakethe angenayo (i-ingress).

Ukuvikeleka kwehla ekusebenziseni amasiginesha edijithali ukuze kuqinisekiswe amakheli okubuyisela ezingeni le-kernel. Isiginesha igcinwa kumabhithi angaphezulu angasetshenzisiwe ephoyinti ngokwalo. Ngokungafani nokuqaliswa kwesofthiwe, ukudalwa nokuqinisekiswa kwamasignesha edijithali kwenziwa kusetshenziswa imiyalelo ekhethekile ye-CPU.
    • Kwengeziwe ikhono lokuvikela indawo yenkumbulo ekubhaleni usebenzisa i-userfaultfd() ikholi yesistimu, eklanyelwe ukuphatha amaphutha ekhasi (ukufinyelela kumakhasi enkumbulo angabelwe) endaweni yomsebenzisi. Umqondo uwukusebenzisa i-userfaultfd() kokubili ukuthola ukwephulwa kokufinyelela emakhasini amakwe njengavikelwe ngokubhaliwe futhi ushayele isibambi esingaphendula kuleyo mizamo yokubhala (isibonelo, ukuphatha izinguquko phakathi nokudalwa kwezifinyezo ezibukhoma zezinqubo ezisebenzayo, isimo. bamba lapho ulahla ukulahlwa kwememori kudiski, usebenzisa inkumbulo eyabiwe, ukulandelela izinguquko kwimemori). Ukusebenza kulingana usebenzisa i-mprotect() ngokuhambisana nesibambi sesignali ye-SIGSEGV, kodwa isebenza ngokushesha okubonakalayo.
    • I-SELinux ihoxise ipharamitha ye-"checkreqprot", ekuvumela ukuthi ukhubaze ukuhlola kokuvikela inkumbulo lapho ucubungula imithetho (ivumela ukusetshenziswa kwezindawo zememori ezisebenzisekayo, ngaphandle kwemithetho eshiwo emithethweni). Ama-symlink e-Kernfs avunyelwe ukuthi athathe ifa umongo wezinkomba zabo zabazali.
    • Ukuqanjwa kuhlanganisiwe module KRSI, okuvumela ukuthi unamathisele izinhlelo ze-BPF kunoma yiziphi izingwegwe ze-LSM ku-kernel.
