ILinus Torvalds imemezele kuleli Sonto ukutholakala okujwayelekile kwenguqulo 5.6 ye-Linux kernel ngemuva kwama-CR ahlukahlukene ashicilelwe. I-Linux 5.6 iqukethe izinguquko eziningi nokuthuthuka. Njengayo yonke inguqulo entsha yolayini omkhulu wentuthuko, okusha kakhulu kuletha izinguquko ezingaphezu kwezinkulungwane eziyishumi, ezinye zivuselela imisebenzi emisha, ezinye zithuthukise ezikhona kakade.
Izici ezibalulekile zale nguqulo faka ukwesekwa kwe-Arm EOPD, izikhala zamagama wesikhathi, I-BPF dispatcher kanye ne-batch BPF card works kanye ne-openat2 call, ukuqaliswa kwe-VPN WireGuard njll.
Ukuhambisana kwe-USB 4
Izinga le-USB 4 lingesinye sezici eziyinhloko yale nguqulo ye-Linux Kernel kusukela Ukusekelwa kwe-USB4 kwaqaliswa okususelwa kuchazwe kwe-Thunderbolt 3. Ngokombono, isivinini singafinyelela kuma-40 Gb / s ngesixhumi se-USB-C, ngaphezu kwe- amandla wokusekela afinyelela kuma-watts ayi-100 nge-PD port (Ukulethwa kwamandla). I-USB4 ikuvumela ukuthi uxhume izibonisi ezingama-4K noma eziyi-8K ku-USB, futhi uxhume nochungechunge lwamadivayisi amaningi e-USB kuketanga echwebeni elifanayo.
Lobu buchwepheshe bokuxhuma, obaphothulwa ehlobo eledlule futhi bavela kuThunderbolt 3, kufanele ngabe sebivele kumasistimu ezinyangeni ezimbalwa. Amaprosesa wesizukulwane se-Intel Tiger Lake, adla ifa lamanje lama-processor we-Ice Lake wedeskithophu namalaptop, kufanele asekwe.
Ukulungiswa kwamaphutha ngonyaka ka-2038
Olunye ushintsho oluza ku-Linux 5.6 ngu iphutha lonyaka ka-2038 elithinta izakhiwo ezingama-32-bit ngenxa yenkinga yokuchichima kwenamba.
Eqinisweni, i-Unix neLinux zigcina inani lesikhathi ngefomethi yenombolo engama-32 esayiniwe enenani eliphakeme elingu-2147483647. Ngaphandle kwale nombolo, ngenxa yokuchichima kwenani, amanani azogcinwa njengenombolo engemihle Lokhu kusho ukuthi ngohlelo lwama-32-bit, inani lesikhathi alikwazi ukweqa amasekhondi angama-2147483647 ngemuva kukaJanuwari 1, 1970.
Ngamagama alula, ngemuva kuka-03: 14: 07 UTC ngoJanuwari 19, 2038, ngenxa yokuchichima kwenamba, isikhathi kuzoba ngoDisemba 13, 1901 esikhundleni sikaJanuwari 19, 2038.
Ukusekelwa kwe-WireGuard
I-Linux 5.6 iza nobuchwepheshe be-Wireguard VPN, ubekhuluma kakhulu ngaye isikhashana. Lokhu kufanele, phakathi kwezinye izinto, kube yi-a ukusungulwa kokuxhumeka okusheshayo, ukusebenza okuhle nokusingathwa okuqinile, okusheshayo nokusobala ukuxhumana kukhipha. Ngaphezu kwalokho, ubuchwepheshe bomhubhe isebenza kahle kakhulu futhi kulula kakhulu ukuyilungisa kunobuchwepheshe obudala be-VPN; I-Wireguard inikeza ukuphepha ekulahlekelweni kwe-evesdropping ngama-encryption algorithm amasha.
I-WireGuard isebenzisa i-Curve25519 ukushintshanisa ukhiye, i-ChaCha20 ukubethela, I-Poly1305 yokufakazela ubuqiniso bedatha, i-SipHash okhiye be-hashtable, kanye ne-BLAKE2s ye-hash. Ixhasa u-Layer 3 we-IPv4 ne-IPv6 futhi ingafaka i-v4-in-v6 futhi ngokufanayo. I-WireGuard yamukelwe abanye abahlinzeki bezinsizakalo zeVPN abanjengoMullvad VPN, AzireVPN, IVPN, kanye ne-cryptostorm, isikhathi eside ngaphambi kokufakwa kwayo kwiLinux, ngenxa yedizayini yayo "enhle kakhulu".
Ukusekelwa kwe-ARM EOPD
Ngenxa yokuba sengozini kweMeltdown okuvumela umhlaseli esikhaleni somsebenzisi ukuthi afunde idatha kusuka esikhaleni se-kernel kusetshenziswa inhlanganisela yokwenziwa kokuqagela neziteshi zezingane ezisuselwa kunqolobane. Ukuzivikela kwekernel ngokumelene neMeltdown ukuhlukaniswa kwamatafula ekhasi le-kernel, isusa ngokuphelele amatafula ekhasi le-kernel kusuka kumephu yesikhala somsebenzisi. Kuyasebenza kodwa inezindleko zokusebenza ezibaluleke kakhulu futhi kungaphazamisa ukusetshenziswa kweminye imisebenzi yeprosesa.
Kodwa-ke, kwamukelwa kabanzi ukuthi ukuhlukaniswa kwesikhala sekheli kuzodingeka kakhulu ukuvikela amasistimu esikhathini esizayo.
Kukhona okunye, okuyisinyathelo esuselwa ku-E0PD, engezwe njengengxenye yezandiso ze-Arm v8.5. E0PD kuqinisekisa ukufinyelela kusuka esikhaleni somsebenzisi kuye maphakathi nememori khadi I-kernel ihlala yenziwa ngesikhathi esingaguquguquki, ngaleyo ndlela igweme ukuhlaselwa kokuvumelanisa.
Ngakho-ke I-E0PD ayikuvimbeli ukuthi isebenze ngokuqagela kwimemori lapho isikhala somsebenzisi kungafanele sikwazi ukufinyelela khona, kepha ivimba isiteshi eseceleni esivame ukusetshenziselwa ukukhipha idatha kuvezwe yimisebenzi eqagelwe kabi.
Okokugcina uma ufuna ukwazi kabanzi ngayo, ungabonisana isixhumanisi esilandelayo.
