Emva kweenyanga ezimbini zophuhliso, I-Linus Torvalds ivelise inguqulelo entsha ye "Linux Kernel 5.7" apho utshintsho olwahlukileyo lubonakala khona, njenge umiliselo olutsha lweFS exFAT, Imodyuli ye-bareudp yokwenza iitonela ze-UDP, Ukuqinisekiswa okusekwe kwisikhombisi kukhuseleko lwe-ARM64, Isakhono sokuncamathisela iinkqubo ze-BPF kubalawuli be-LSM, umiliselo olutsha lwe-Curve25519, isixhobo sokukhusela ukwahlulahlula, ukuhambelana kweBPF nePREEMPT_RT nokunye okuninzi.
Le nguqulo intsha yamkele ukulungiswa kwe-15033 ukusuka kubaphuhlisi bango-1961, Ubungakanani beepatch ngu-39MB (utshintsho oluchaphazele iifayile ezili-11590, imigca engama-570560 yekhowudi eyongeziweyo, imigca engama-297401 isusiwe). Phantse iipesenti ezingama-41 zazo zonke iinguqu ezenziwe ngo-5.7 zinxulumene nabaqhubi bezixhobo, malunga neepesenti ezili-16 zotshintsho zinxulumene nokuhlaziya ikhowudi ethile yoyilo lwezixhobo.
Yintoni eNtsha kwiLinux Kernel 5.7
Kule nguqulo intsha a umiliselo olutsha lomqhubi we-exFAT, esekwe ngoku "sdfat" (2.x) ikhowudi esekwe yiSamsung. Umqhubi ebekongezwe ngaphambili kwi-kernel ibisekwe kwikhowudi ye-Samsung ephelelwe lixesha (inguqulelo 1.2.9) kwaye ishiye umva umqhubi omtsha malunga ne-10% ekusebenzeni.
Kwimeko yeXFS, ukuqinisekiswa kwemethadatha kunye nokuphunyezwa kwe-fsck kuphuculwe izahlulelo ezisebenzayo. Ithala leencwadi licetyiswa ukuba kwakhiwe kwakhona izakhiwo ze-btree, eziza kuthi kamva zisetyenziselwe ukulungisa i-xfs_repair kunye nokuqonda ukubakho kokuphinda kuphile ngaphandle kokudiliza isahlulelo.
Kwicandelo lenkqubo esezantsi yenethiwekhi, I-Netfilter ibandakanya utshintsho olukhawulezisa kakhulu ukwenziwa kweseti enkulu yezinto ezingafunekiyo, ezifuna ukuqinisekiswa ngokudityaniswa kwee-subnet, i-network port, protocol, kunye ne-MAC.
Ngaphandle koko kuyacaciswa ukuba yongeze inkxaso yeendlela zokukhawulezisa izixhobo zekhompyuter zokufaka isakhelo se-Ethernet Ngo-802.11 (iWi-Fi).
Kwamkelwe isinye kwisithathu seepatches esiguqulela ioctl () izixhobo ze-ethtool zokusebenzisa ujongano lwenethiwekhi. Ujongano olutsha lwenza lula ukongeza izandiso, luphucula ukuphathwa kwempazamo, likuvumela ukuba uthumele izaziso xa imeko itshintsha, yenza lula unxibelelwano phakathi kwekernel kunye nendawo yomsebenzisi, kwaye inciphise inani lodweliso olunamagama.
Ngelixa lokubonwa kunye nokhuseleko ukumiliselwa kwehardware yokuQinisekiswa kwesiKhombisi kongezwe, usebenzisa imiyalelo ekhethekileyo I-ARM64 CPU ukukhusela ngokuchasene nokuhlaselwa kusetyenziswa ubuchule beROP apho umhlaseli angazami ukubeka ikhowudi yakhe kwimemori, kodwa endaweni yoko isebenza kwizicucu zemiyalelo yomatshini esele ikwilayibrari elayishiwe ephela ngomyalelo wolawulo lokubuya.
Kwi-SELinux, iparameter "checkreqprot" isusiwe, ukuvumela ukuba ukhubaze inkumbulo yokujonga ukukhuselwa xa kusenziwa imigaqo (ivumela ukusetyenziswa kweendawo zememori ezisebenzayo, ngaphandle kweemfuno ezichazwe kwimigaqo). Amakhonkco okomfuziselo we-kernfs angawudla ilifa umxholo wabazali.
Inkxaso eyongeziweyo ye-EFI mode boot exubeneyo, evumela ukulayishwa kwe-64-bit kernel kwi-32-bit firmware eqhuba kwi-64-bit CPU ngaphandle kokusebenzisa i-boot loader ekhethekileyo.
Ngaphandle koko Inkqubo enikwe amandla okuchonga kunye nokulungisa isitshixo sokwahlula kubonakalisiwe, Oku kwenzeka xa ufikelela kwidatha engalunganga kwimemori ngenxa yokuba xa idatha yemiyalelo ye-athomu iwele ngemigca emibini ye-CPU.
Izitshixo ezinjalo zikhokelela ekwehleni okukhulu kwintsebenzo (i-1000 imijikelezo icotha kunokwenziwa kweathom enedatha ewela kumgca ofanayo we-cache). Kuxhomekeka kwi "split_lock_detect" iparameter yesiqalo, i-kernel iyakwazi ukubona oko kutshixwa kubhabho kwaye ikhuphe izilumkiso okanye ithumele uphawu lwe-SIGBUS kwisicelo esenze ingozi.
Ukukhuphela
Gqibela ukuba ufuna ukwazi ngakumbi ngayo Malunga nale nguqulo intsha yeLinux Kernel, ungajonga kuluhlu olupheleleyo lwe utshintsho kwikhonkco elilandelayo.
Ngokumalunga nokufumaneka kwenguqulelo entsha, kuya kufuneka uyazi ukuba ngoku iyafumaneka ukukhuphela kunye nokudityaniswa ukusuka kwisiza I-Linux kernel iwebhusayithi esemthethweni, Ngelixa kwimeko yeenguqulelo esele zicwangcisiwe zolwabiwo oluthile, sele zifumaneka kwezinye.
