Ngemva kwezinyanga ezimbili zokuthuthukiswa, uLinus Torvalds ukhiphe inguqulo 5.5 ye-Linux kernel . Phakathi kwezinguquko eziphawuleka kakhulu kule nguqulo yikhono lokunikeza amagama ahlukile kuma-interface enethiwekhi, ukuhlanganiswa kwemisebenzi ye-cryptographic kusuka kulabhulali ye-Zinc, ikhono lokuphinda amadiski angaphezu kwamabili ku-Btrfs RAID 1, indlela yokuqapha isimo sama-patches abukhoma, uhlaka lokuhlola i-kunit drive, ukusebenza okuthuthukisiwe kwe-wireless stack ye-mac80211, ikhono lokufinyelela i-root partition nge-protocol ye-SMB, nokunye okuningi.
Inguqulo entsha yamukele ama-patches onjiniyela angu-15505, anosayizi we-patch ongu-44 MB (izinguquko zithinte amafayela angu-11781, zengeza imigqa yekhodi engu-609208 futhi zasusa imigqa engu-292520). Cishe u-44% wazo zonke izinguquko kunguqulo 5.5 zihlobene nabashayeli bedivayisi, cishe u-18% ezibuyekezweni zekhodi ethile yesakhiwo sehadiwe, u-12% esitokisini senethiwekhi, u-4% ezihlelweni zamafayela, kanye no-3% ezihlelweni zangaphakathi ze-kernel.
Izinto ezintsha ezintsha zeLinux Kernel 5.5
Kule nguqulo entsha ye-Linux Kernel 5.5, ukwesekwa kwama-xxhash64, blake2b, kanye nama-sha256 checksums kwengezwe ohlelweni lwefayela lwe -Btrfs .
Ekusetshenzisweni kwe-RAID1 , kungenzeka ukukopisha idatha kumadivayisi amathathu ( raid1c3) noma amane (raid1c4) (ngaphambilini ukukopisha kwakukhawulelwe kumadivayisi amabili), okuvumela idatha ukuthi ilondolozwe ngenkathi kulahlekelwa amadivayisi amabili noma amathathu ngesikhathi esisodwa.
Nakuba i-Ext4 inikeza ikhono lokusebenzisa amabhlogo amancane ukuze abethelwe (ngaphambilini, ukubethela kwakwenziwa kuphela ngamabhlogo anosayizi ofana nosayizi wamakhasi ememori (4096)).
I-F2FS isebenzisa imodi yokuphina amafayela enokuqondaniswa eceleni komphetho we-2MB ukuze ibekwe engxenyeni efanele ngokuphelele, okuqinisekisa ukungabikho kokusatshalaliswa kabusha kwaleli fayela ngumqoqi kadoti.
Esinye isici esisha esibalulekile ukwesekwa okwengeziwe kokuqapha isimo sezinzwa zokushisa zedivayisi ye-NVMe kusetshenziswa i-hwmon API (ehambisana nama-libsensors kanye nomyalo "wezinzwa"), ongadingi amalungelo aphezulu ukuze ufinyelele (ngaphambilini, ulwazi lokushisa lwalubonakala ku-"smart log", eyayitholakala kuphela ku-root).
Ngaphezu kwalokho, njengengxenye yephrojekthi enkulu yokuhlanganisa i-WireGuard VPN , izici eziningi ezivela kulabhulali ye-cryptographic ye-Zinc zathunyelwa ku- Crypto API ejwayelekile, okuhlanganisa nokusetshenziswa okusheshayo kwama-algorithms e-ChaCha20 kanye ne-Poly1305.
I- x86 architecture KVM hypervisor inikeza ikhono lokucubungula amathebula ahlanganisiwe amazinga amahlanu amakhasi enkumbulo futhi ingeza ukwesekwa kwemiyalelo ye-XSAVES yamaprosesa e-AMD. Kumaprosesa e-ARM64, ikhono lokudlulisa ulwazi lwesikhathi lengeziwe.
Ukusekelwa komsebenzi we-blake2b hash kufakwe ohlelweni olungaphansi lwe-cryptographic, okunikeza ukusebenza okuphezulu kakhulu kokubala i-hash ngenkathi kugcinwa ukuthembeka ezingeni le-SHA-3, kanye nenguqulo emfushane ye-Blake2s.
Olunye ushintsho olubalulekile kule nguqulo entsha ye-Linux Kernel 5.5 yindlela entsha yokwabela amagama ahlukile kuma-interface enethiwekhi, okuvumela amagama amaningi ukuthi asetshenziswe ngesikhathi esisodwa ku-interface (kufaka phakathi ukusetshenziswa kwamathempulethi amaningi e-udev).
Usayizi wegama angafika ezinhlamvini eziyi-128 (phambilini igama lesibonisi senethiwekhi lalinqunyelwe ezinhlamvini eziyi-16)
Ukuze ungeze igama elengeziwe, sebenzisa umyalo othi " ip link prop add " (isibonelo, " ip link prop add enx00e04c361e4c altname someothername "). Ukuqaliswa kusekelwe ekufakazeni izakhiwo ezengeziwe ku-interface futhi kungandiswa esikhathini esizayo ngamanye amapharamitha, kungagcini nje ngamagama ahlukile.
Okokugcina, uma ufuna ukufunda kabanzi ngohlu oluphelele lwezinguquko ezifakiwe kule nguqulo entsha ye-Linux Kernel, ungayibheka kusixhumanisi esilandelayo.
Mayelana nokutholakala kwenguqulo entsha, ungalanda ikhodi ukuhlanganisa iKernel kuwebhusayithi yayo esemthethweni noma ulinde amaphakheji ahlanganisiwe ukuthi afakwe kumakhosombe wokusabalalisa kwakho.
