Ukukhutshwa kwe-kernel ye-Linux 5.7

Emva kweenyanga ezimbini zophuhliso, uLinus Torvalds wazisiwe ukukhutshwa kwe-kernel Linux 5.7. Phakathi kwezona nguqu ziphawulekayo: ukuphunyezwa okutsha kwenkqubo yefayile ye-exFAT, imodyuli ye-bareudp yokudala iitonela ze-UDP, ukhuseleko olusekwe kungqinisiso lwesalathisi se-ARM64, ukukwazi ukuncamathisela iinkqubo ze-BPF kubaphathi be-LSM, ukuphunyezwa okutsha kwe-Curve25519, ukwahlula- umtshina wokutshixa, ukuhambelana kwe-BPF kunye ne-PREEMPT_RT, ukususa umda kumgca we-80-ubungakanani bomgca kwikhowudi, kuthathelwa ingqalelo izikhombisi ze-CPU zobushushu kumcwangcisi wemisebenzi, ukukwazi ukusebenzisa i-clone () ukuzala iinkqubo kwelinye iqela, ukukhuselwa ekubhaleni. kwinkumbulo usebenzisa userfaultfd.

Inguqulelo entsha ibandakanya ukulungiswa kwe-15033 evela kubaphuhlisi be-1961,
ubungakanani bepatch - 39 MB (utshintsho oluchaphazelekayo kwiifayile ze-11590, zongezwa imigca ye-570560 yekhowudi,
297401 imiqolo isusiwe). Malunga ne-41% yazo zonke ezithiwe thaca kwisi-5.7
utshintsho lunxulumene nabaqhubi besixhobo, malunga ne-16% yotshintsho
isimo sengqondo malunga nokuhlaziya ikhowudi ethile kwi-architecture ye-hardware, i-13%
ehambelana ne-stack yenethiwekhi, i-4% kwiinkqubo zefayile kunye ne-4% yangaphakathi
iinkqubo ezisezantsi zekernel.

Siseko ezintsha:

• Inkqubo engaphantsi kweDisk, I/O kunye neeNkqubo zeFayile
  • Kongezwe ukuphunyezwa komqhubi omtsha we-exFAT, yasekwa ngokusekelwe kwisiseko sekhowudi yangoku "sdfat" (2.x) ephuhliswe yi-Samsung kwii-smartphones zayo ze-Android. Umqhubi wongezwa ngaphambili kwi-kernel wayesekelwe kwikhowudi ye-Samsung yelifa (uhlobo lwe-1.2.9) kwaye yayimalunga ne-10% emva komqhubi omtsha ekusebenzeni. Masikhumbule ukuba ukongeza inkxaso ye-exFAT kwi-kernel yenzeka emva kweMicrosoft ipapashiwe iinkcukacha zoluntu kunye ne-patent ze-exFAT zenziwe zifumaneke ukuze zisetyenziswe simahla kwi-Linux.

  • Kwi-dm_integrity yongezwe inkxaso yokusebenza "yokulahla".
  • Kwi-null_blk yongezwe inkxaso yokutshintshwa kwempazamo ukulinganisa ukusilela ngexesha lovavanyo.
  • Yongeziwe ukukwazi ukuthumela izaziso ze-udev malunga nokutshintsha kobungakanani besixhobo.
• Inkqubo engaphantsi yothungelwano
  • I-Netfilter ibandakanyiwe utshintsho, ikhawulezisa ngokuphawulekayo ukusetyenzwa koluhlu lomdlalo omkhulu (iiseti ze-nftables), ezifuna ukukhangela indibaniselwano ye-subnets, izibuko zenethiwekhi, iprotocol kunye needilesi ze-MAC.
    Ukuphucula yaziswa kwimodyuli ye-nft_set_pipapo (PIle PAcket Policies), esombulula ingxaki yokuthelekisa imixholo yepakethi enoluhlu olungenamkhethe lwemeko yendawo esetyenziswa kwimithetho yokucoca, njenge IP kunye noluhlu lwezibuko lomnatha (nft_set_rbtree kunye nft_set_hash sebenzisa isithuba sokuthelekisa kunye nokubonisa ngokuthe ngqo amaxabiso. ). Uguqulelo lwe pipapo vectorized usebenzisa 256-bit imiyalelo AVX2 kwinkqubo nge AMD Epyc 7402 iprosesa ibonise i-420% ukwanda ukusebenza xa ukwahlula 30 amawaka iirekhodi kuquka port-protocol indibaniselwano. Ukunyuka xa kuthelekiswa indibaniselwano ye-subnet kunye nenombolo yezibuko xa kucazululwa iirekhodi ze-1000 kwakuyi-87% ye-IPv4 kunye ne-128% ye-IPv6.

  • Yongeziwe imodyuli ye-bareudp, ekuvumela ukuba udibanise iprotocol ezahlukeneyo ze-L3, njengeMPLS, IP kunye ne-NSH, kwitonela ye-UDP.
  • Ukuhlanganiswa kwamacandelo e-MPTCP (i-MultiPath TCP), ukwandiswa kwe-protocol ye-TCP yokuququzelela ukusebenza koxhulumaniso lwe-TCP kunye nokuhanjiswa kweepakethi ngaxeshanye kunye neendlela ezininzi ngokusebenzisa i-interfaces ezahlukeneyo zenethiwekhi ezibophelelwe kwiidilesi ze-IP ezahlukeneyo, kuye kwaqhubeka.
