Inguqulo entsha yeLinux Kernel 5.5 isivele ikhishiwe futhi lezi yizindaba zayo

Ngemuva kwezinyanga ezimbili zentuthuko, ILinus Torvalds yethule inguqulo ye-Linux kernel 5.5, inguqulo lapho phakathi kwezinguquko eziphawuleka kakhulu, singamtholaikhono lokwabela amanye amagama kuma-interface enethiwekhi, ukuhlanganiswa kwemisebenzi ye-cryptographic yelabhulali yeZinc, ikhono lokulingisa ngaphezu kwama-disk angu-2 ku-Btrfs RAID1, indlela yokuqapha isimo sezimagqabhagqabha ezibukhoma, uhlaka lokuhlolwa kweyunithi le-kunit, ukusebenza okwandisiwe kwesitaki esingenantambo se-mac80211, amandla okufinyelela ukwahlukanisa izimpande nge-SMB protocol nokunye okuningi.

Uhlobo olusha lwamukele izingqimba zonjiniyela eziyi-15505, usayizi wepatch ungama-44MB (ushintsho luthinte amafayela ayi-11781, imigqa engama-609208 yekhodi ingeziwe, kususwe imigqa engama-292520) Cishe u-44% wazo zonke izinguquko ezethulwe ku-5.5 ahlobene nezishayeli zedivayisi, cishe u-18% wezinguquko uhlobene nokuvuselela ikhodi ethile yezakhiwo zehadiwe, i-12% ixhunywe kusitaki senethiwekhi, i-4% yokufaka amasistimu kanye ne-3 % kumasistimu angaphansi we-kernel.

Izinto ezintsha ezintsha zeLinux Kernel 5.5

Kule nguqulo entsha yeLinux Kernel 5.5 ukusekelwa kwe-xxhash64, blake2b, ne-sha256 checksums ukuze uhlelo lwefayela Ama-Btrfs.

Ekuqalisweni kwe- I-RAID1, kungenzeka ukuphinda idatha kokuthathu (nokuthula1) noma ezine (nokuthula1) amadivaysi (isibuko sangaphambilini besilinganiselwe kumadivayisi amabili), sikuvumela ukuthi ugcine idatha ngenkathi ulahlekelwa amadivayisi amabili noma ama-2 ngasikhathi sinye.

Ngesikhathi I-Ext4 inikeza amandla okusebenzisa amabhlogo amancane ukubethela (Ngaphambilini, ukubethela kwakwenziwa kuphela ngamabhulokhi asayizi wawo afana nosayizi wamakhasi wememori (4096))

En I-F2FS isebenzisa imodi yokuphina ifayili ngokuqondanisa eceleni konqenqema lwe-2 MB ukuze kubekwe esigabeni esifanele ngokuphelele, kuqinisekiswe ukungabikho kokusabalalisa kabusha leli fayela ngumqoqi kadoti.

Okunye okusha okubalulekile yi- ungeze ukusekelwa ukuqapha isimo se- izinzwa Ithempelesha yedivayisi ye-NVMe usebenzisa i-hwmon API (ehambisana nabasizi be-libsensors kanye nomyalo "wezinzwa"), ongadingi amalungelo aphakeme ukufinyelela (ngaphambili, imininingwane yokushisa ibonakalisiwe ku- "smart log", ebitholakala kuphela ngezimpande).

Ngaphezu kwalokho, njengengxenye yephrojekthi enkulu yokuhlanganisa ye- I-WireGuard VPN, imisebenzi eminingi yelabhulali ye-crypto yeZinc zidluliselwe ku-Crypto API okujwayelekile, kufaka phakathi ukusetshenziswa okusheshayo kwama-algorithm we-ChaCha20 ne-Poly1305.

En i-KVM hypervisor x86 izakhiwo se inikeza amandla okucubungula amatafula asezingeni afihlekile amakhasi ememori futhi engeza ukusekelwa kwemiyalo ye-XSAVES yamaprosesa we-AMD. Kumaprosesa we-ARM64, amandla wokudlulisa imininingwane yesikhathi afakiwe.

Tambien ungeze ukusekelwa komsebenzi we-blake2b hash ohlelweni olungaphansi lwe-crypto, olunikeza ukusebenza kwe-hashing okuphezulu kakhulu ngenkathi kugcinwa ukuthembeka ezingeni le-SHA-3, kanye nohlobo olufushane lwamaBlake2s.

Olunye ushintsho oluphawulekayo lwale nguqulo entsha yeLinux Kernel 5.5 kuyinto indlela entsha yokwabela amanye amagama kuzindawo zokuxhumana zenethiwekhi, okuvumela amagama amaningi ukuthi asetshenziswe ngasikhathi sinye esibonakalayo (kufaka phakathi ukusetshenziswa kwezifanekiso eziningi ze-udev).

Usayizi wegama angafika ezinhlamvini eziyi-128 (phambilini igama lesibonisi senethiwekhi lalinqunyelwe ezinhlamvini eziyi-16)

Ukuze unamathisele igama elengeziwe, sebenzisa umyalo «ip link prop engeza" (Ngokwesibonelo, "ip link prop engeza i-enx00e04c361e4c altname someothernamfuthi "). Ukuqaliswa kusekelwe ekuhlanganiseni izakhiwo ezengeziwe kusixhumi esibonakalayo futhi kunganwetshwa ngokuzayo ngamanye amapharamitha, kungagcini kwamanye amagama.

Ekugcineni, uma ufuna ukwazi kabanzi ngohlu oluphelele lwezinguquko ezifakwe kule nguqulo entsha yeLinux Kernel, ungayithinta Kulesi sixhumanisi esilandelayo.

Mayelana nokutholakala kwenguqulo entsha, ungalanda ikhodi ukuhlanganisa iKernel kuwebhusayithi yayo esemthethweni noma ulinde amaphakheji ahlanganisiwe ukuthi afakwe kumakhosombe wokusabalalisa kwakho.
