Fedora 34 inotarisira kubvisa SELinux kuremara uye kutamira kune KDE kubva Wayland

Kushanda mukati meFedora hakumire uye ndezvekuti ivo vagadziri vakapa izvo zvavanotaura nezvazvo uye nguva ino hazvisi zveiyo inotevera vhezheni yeFedora 33 asi izvo ivo vakatove vakatarisana neFedora 34.

Uye ndizvozvo munguva pfupi yapfuura pane zvinyorwa zvinyorwa Nhaurirano dzakasiyana dzakatanga kubuda pamusoro peshanduko dzakasiyana dzakatsanangurwa kuiyi vhezheni yekugovera. Imwe yeshanduko dzakatsanangurwa ndiko kubviswa kwerutsigiro rwekuremadza iyo SELinux nguva yekumhanya.

Imomo yeiyo Fedora 34 kuitiswa, shanduko inotsanangurwa kubvisa kugona kudzima SELinux panguva yekumhanya.

Nepo iko kugona kwekuchinja pakati pekumanikidza uye nekutendera nzira kuchachengetedzwa panguva yekutanga. Mushure meSELinux kutanga, Vatyairi veLSM vanozoiswa mune yekuverenga-chete maitiro, iyo inovandudza dziviriro kubva pakurwiswa kunoitirwa kuremadza SELinux mushure mekushandisa kusagadzikana kunogona kuchinja zvirimo mune memory kernel.

Kuti udzivise SELinux, ingoitazve sisitimu neparameter "selinux = 0" pamutsetse wekernel wekuraira.

Kunze kwaizvozvo zvinonzi kusagadziriswa hakugone kutsigirwa kuchinja kumisikidzwa kwe / etc / selinux / config (SELINUX = yakaremara). Pakutanga, kutsigira kurodha pasi module yeSELinux kwakadzoserwa muLinux 5.6 kernel.

Tsigiro yekuremadza iyo SELinux nguva yekumhanyisa kuburikidza »/ etc / selinux / config» yakatanga kugadzirwa kuti iite nyore kugoverwa kweLinux kutsigira zvivakwa uko kuwedzera paramende kumutemo wekernel kwainetsa.

Nehurombo, kutsigira nguva yekumhanya kuremadza kwaireva kuti taifanirwa kugadzira mamwe ekuchengetedza tradeoffs kana zvasvika kune kernel LSM hooks.

Kumaka kernel LSM zvikorekedzo sekuverenga-chete zvinopa zvimwe zvekuchengetedza mabhenefiti, asi zvinoreva kuti hatichakwanise kudzima SELinux panguva yekumhanya.

Imwe shanduko yakataurwa mukati mekutumira mazita eFedora 34, ndizvo inofunga kushandura default inovaka neiyo KDE desktop kuti ishandise Wayland nekumira, uko chikamu cheX11 chinotarisirwa kuve sarudzo.

Parizvino, iro KDE rinoshanda pamusoro peWayland nderekuyedza, asi muKDE Plasma 5.20 iyi nzira yekushanda ichave yakagadzirirwa mukushanda pamwe neyekushandisa modhi pamusoro peX11.

==== Wayland yakagadzirira? ====
Wayland yanga ichishandiswa nekutadza kweFedora Workstation kubvira Fedora 25. Uye kunyangwe zvaive zvisina kukura pakutanga, nhasi chiitiko chakasimba kwazvo mune zvese zvese.

Padivi re KDE, rakakomba basa rekutsigira Wayland rakatanga nguva pfupi GNOME ichinjira kuWayland nekukanganisa Kusiyana neGNOME, KDE ine seti yakafara yezvishandiso, uye zvakatora nguva yakareba kuti isvike inoshandisika nyika. Iine Plasma vhezheni 5.20, iyo Wayland protocol ye
screencasting uye yepakati bhatani kunamatira pakupedzisira inotsigirwa,
kupedzisa seti inodiwa yemabasa kuchinjira kuWayland
default.

Kubatanidzwa kwechikamu KDE 5.20 yakavakirwa Wayland ichatarisa screencast uye epakati kubaya nyaya. Iyo kwin-wayland-nvidia package inozoshandiswa kushanda kana uchishandisa muridzi weNVIDIA madhiraivha. X11 rutsigiro ruchapihwa kuburikidza nechikamu cheXWayland.

Sekupokana kupesana chengetedza default chikamu chakavakirwa pa X11, X11 server stall inotaurwa, iyo yakamira zvakanaka kwazvo kusimudzira mumakore achangopfuura uye inongogadzirisa zvembugs zvine njodzi uye kushomeka mukodhi.

==== Zvakadii neNVIDIA? ====
Plasma, muchokwadi, "hongu" inoenderana neNVIDIA GPUs ine muridzi weWayland mutyairi. Inofanirwa kwin-wayland-nvidia iyo kwin-wayland-nvidia package. Saka tarisiro ndeyekuti ese makuru maGPU anoshanda zvakanaka.

Kufambisa iyo default kuvaka kuWayland kunosimudzira kwakawanda basa rekuvandudza rine chekuita nerutsigiro rwemagetsi matsva emifananidzo muKDE, sezvo budiriro yaive panguva yakakodzera inoratidzwa mukutamisirwa kwechikamu cheGNOME paFedora 25 kuenda Wayland.
