Iyo Linux kernel 5.6 iri pano uye idzi ndidzo nhau dzayo

Mushure memwedzi miviri yekuvandudza, Linus Torvalds yakaunza iyo nyowani Linux kernel vhezheni 5.6, vhezheni iyo inosvika neshanduko dzakasiyana uye nhau uye pakati pechakakurumbira shanduko kusanganisa kweiyo interface WireGuard VPN, USB4 rutsigiro, nzvimbo dzemazita yenguva, iko kugona kwekugadzira TCP kusanganisa vatongi vachishandisa BPF, kutanga rutsigiro rweMultipath TCP, bug 2038 kernel kubvisa, bootconfig mashandiro, uye ZoneFS FS.

Iyi vhezheni nyowani yakagamuchira huwandu hwemakumi matatu nematatu emapatch Kunze kweva 1810 vanogadzira, chigamba kukura kuri 40MB (shanduko dzakabata 11577 mafaera, 610012 mitsara yekodhi yakawedzerwa, mitsara 294828 yabviswa).

Main nyowani maficha eLinux 5.6

Imwe yemabhuku makuru eiyi vhezheni nyowani ndiyo kuitiswa kweiyo WireGuard VPN interfaceque inoshandisa hwaro hwazvino nzira dzekunyorera (ChaCha20, Poly1305, Curve25519, BLAKE2s), iri nyore kushandisa, haina matambudziko, Yakave yakaratidzirwa mune yakawanda nhamba yakakura deployments uye inopa kwakanyanya kwazvo kuita (3.9x nekukurumidza kupfuura OpenVPN Bandwidth).

Imwe yeshanduko inomira mushanduro iyi nyowani ndiyo kubatanidzwa kwezvinhu zvinoda kutsigira MPTCP (MultiPath TCP) uye TCP protocol yekuwedzera yekuronga iyo TCP-yekubatanidza pamwe nekuendeswa kwemapaketi panguva imwechete munzira dzinoverengeka kuburikidza neakasiyana maratidziro epamhepo akabatanidzwa kune akasiyana IP kero.

Zvemashandisirwo enetiweki, akadaro kubatana kwakawedzerwa inoita kunge yakajairwa TCP kubatana uye ese kuyerera kwekuparadzanisa pfungwa kunoitwa neMPTCP. Multipath TCP inogona kushandiswa zvese kuwedzera kuita uye kuwedzera kuvimbika.

Kune rimwe divi, zvinoratidzwa izvo iyo kernel yakagamuchira iyo ZoneFS faira system, , que inorerutsa yakaderera-chikamu basa nematanho ekuchengetedza maturusi. Dhiraivhoni dzakatemwa michina iri pane magineti akaomesa dhiraivha kana NVMe SSDs, ine nzvimbo yekuchengetera yakakamurwa kuita matunhu ayo anoumba mapoka emabhuroko kana zvikamu, umo kungowedzerana kwakateedzana kwedata kunotenderwa nekuvandudzwa kweboka rese remabhuroko.

Pamusoro peizvi, iyo kuitiswa kweUSB 4.0 kududzirwa, iyo yakavakirwa paThunderbolt 3 protocol uye inopa bandwidth inosvika ku40 Gb / s, uku uchichengetedza kuenderana neUSB 2.0 uye USB 3.2.

USB 4.0 inobvumira kugadziriswa kwema protocols akasiyana pamusoro peyechete Type-C tambo inosanganisira PCIe, Ratidza Port, uye USB 3.x, pamwe nekushambadzira kwesoftware, semuenzaniso, kuronga netiweki zvinongedzo pakati pevagari.

Iyo yekumisikidza inovaka pamusoro peThunderbolt mutyairi atove akaverengerwa muLinux kernel uye anochinjisa kuti ishande ne USB4 inoenderana mauto nemidziyo.

Nguva yeExt4 optimization yekuita inosanganisirwa zvine chekuita nekubata kweinode kukiya mukuverenga nekunyora mashandiro. Saka iko kunyorazve kuita kwakagadziridzwa muDirect I / O maitiro.

Nezve vatongi iyo shanduko dzakakosha kune ALSA ruzha system. Pane mutungamiriri nouveau dr inowedzera rutsigiro rwechokwadi firmware download mode yeNVIDIA GPUs yakavakirwa paTuring microarchitecture iyo yakaita kuti 3D ikurumidze rutsigiro rwemakadhi aya (yepamutemo firmware ine NVIDIA siginicha yedhijitari inofanira kutorwa), pamwe neiyo tsigiro yekumanikidza kwedata uchifambisa kuburikidza neDisplayPort MST (Yakawanda-Rukova Yekutakura).

Pakupedzisira kwechikamu chegadziriro dzebug mhinduro yedambudziko 2038 inosimbiswa, umo ma driver ekupedzisira asara akatsiviwa, mune iyo 32-bit time_t mhando (yakasainwa int) yakashandiswa pakaunda.

kunze kwaizvozvo tsigiro yeMPX yekuwedzera yakabviswa (Memory Kudzivirirwa Kuwedzeredzwa) yakawedzerwa mune kernel 3.19 uye ichibvumira iyo sangano kutarisa makomba ekucherechedza miganho yenzvimbo dzekurangarira. Iyi tekinoroji haina kunyanyo shandiswa mumakomputa uye yakabviswa kubva kuGCC.

Finalmente kana iwe uchida kuziva iro rakazara runyorwa rwe shanduko kuti iyi vhezheni itsva yeLinux Kernel inosanganisirwa iwe unogona tarisa chinotevera chinongedzo.
