Red Hat Enterprise Linux 8.3 Inosvika neKuvandudzwa, Kernel Enhancements, uye Zvimwe

 

Red Hat yazivisa kuburitswa kweshanduro nyowani yekugovera «Red Hat Enterprise Linux 8.3«, Shanduro inoenda kusvika pakuratidza izvozvoe bazi 8.x irikushanduka zvinoenderana newanofungidzira kutenderera kutenderera, zvinoreva kuti shanduro dzinogadzirwa mwedzi mitanhatu yega panguva yakatarwa.

RHEL's Nyowani Chigadzirwa Chekuvandudza Cycle inosanganisira akawanda akaturikidzana, kusanganisira Fedora sechitubu chekugona nyowani, CentOS Stream yekuwana mapakeji einotevera kuburitswa kweRHEL (RHEL mobile variant), minimalist Universal Base Image (UBI) yekumhanyisa kunyorera mumidziyo iri kwayo yega, uye iyo RHEL Developer Kunyorera kushandisa RHEL yemahara panguva yekusimudzira.

Chii Chitsva muRed Hat Enterprise Linux 8.3

Mune iyi vhezheni itsva rutsigiro rwekuyedza rwakaenderera mberi (Technology Preview) yenmstate, AF_XDP, XDP, KTLS, dracut, kexec inokurumidza kumisikidza, eBPF, igc, NVMe pamusoro peTCP / IP, DAX pane ext4 uye xfs, OverlayFS, Stratis, DNSSEC, GNOME pane ARM, AMD SEV masisitimu eKVM , Intel vGPU.

Mune iyo GNOME Classic nharaunda, iyo chaiyo desktop switch bhatani yaendeswa kukona yezasi yekurudyi uye yakagadzirirwa kunge tambo yezvigunwe.

Iyo giraidhi subsystem DRM (Direct Inopa Maneja) inoenderana neLinux kernel vhezheni 5.3.

Iyo osbuild-composer backend yakatsiviwa. Mifananidzo yemifananidzo yakatsigirwa inosanganisira TAR (.tar), QEMU QCOW2 (.qcow2), VMware Virtual Machine Disk (.vmdk), Amazon Machine Image (.ami), Azure Disk Image (.vhd), uye OpenStack Image (.qcow2). Ext4, yakakamurwa diski, Alibaba Cloud uye Google GCE haisati yavapo. Wakawedzera kugona kuisa chifananidzo mugore.

Ma module ane matavi matsva GCC 10, LLVM 10, Rust 1.43, nginx 1.18, Node.js 14, Perl 5.30, PHP 7.4, Ruby 2.7 akawedzerwa kune AppStream repository. Yakagadziridzwa mapakeji eGit 2.27, Go 1.14.4, Python 3.8.3, uye squid 4.11.

The installer Anaconda yakagadziridzwa kuita vhezheni 33.16.3.1, iyo inoshandisa chikamu saizi kuratidzwa kweNVDIMM, yakavandudzwa IPv6 kumisikidzwa, inobvumidzwa kushandisa isiri-ASCII mavara mune password ye disk encryption, yakaratidza kurudziro chaiyo yekusarudza FS ye / boot, / tmp, / var uye / usr, LUKS2 se inoshandiswa nekutadza midziyo yakavharidzirwa.

Muchidimbu ruzivo hwindo, zvinokwanisika kuseta password yemidzi uye kugadzira mushandisi mutsva padanho pamberi pekutanga kwekumisikidza (kare, matanho aya akaitwa mushure mekutanga kwekumisikidza).

Nekukanganisa, iko kushandiswa kwe Intel TSX (Transactional sync inowedzera) akaremara, Inopa maturusi ekuvandudza mashandiro emashandisirwo akaverengeka nekubvisa zvine simba mashandiro ekufananidza.

Kuwedzeredzwa vakaremara nekuda kwekugona kwekurwiswa kweZombieload iyo inoshandura ruzivo rwunodonha kuburikidza nemumatanho ematanho ayo anoitika kana asynchronous kubvisa nhumbu mashandiro (TAA, TSX Asynchronous Abort) irikumhanya. Kugonesa tsigiro yeTSX, takura kernel ne "tsx = pane" paramende.

Uye zvakare, tinogona kuwana shanduro dzakagadziridzwa dze NetworkManager 1.26.0, sunga 9.11, samba 4.12, gnutls 3.6.14 (ine OCSP stapling rutsigiro), USBGuard 0.7.8 (ine rutsigiro rwezviitiko zveGUI), smartmontools 7.1, Libreswan 3.32 ikozvino SHA-2 uye RSA-PSS zvinoshandiswa pachinzvimbo cheSHA-1 uye RSA-PKCS v1.5, rutsigiro rweXFRMi chaiwo maficha akawedzerwa), powertop 2.12 (ine rutsigiro rweIntel Comet Lake, Skylake uye Jasper Lake), zvakanaka -akagadzirirwa 2.14. 0 (yakagadziridzwa serial console nhoroondo uye yakawedzera irqbalance plugin, pamwe nekugadzirisa kweMarvell ThunderX uye AMD masisitimu), tcpdump 4.9.3, libpcap 1.9.1, memcached 1.5.22, libssh 0.9.4, stunnel 5.56, libkcapi 1.2 0, setools 4.3.0, OpenSCAP 1.3.3, scap-chengetedzo-gwara 0.1.50, clevis 13, fapolicyd 1.0, libseccomp 2.4.3, firewalld 0.8.2, tpm2-maturusi 4.1.1, pacemaker 2.0.4, krb5 1.18.2. 2.1, OpenDNSSEC 1.10.1, tigervnc XNUMX.

Uyewo Zvinosimbiswa kuti basa rakaenderera mberi kudzikamisa masisitimu eBPF. Yakawedzerwa tsigiro izere ye libbpf. MuRHEL 8.3, zvinotevera zvinonzi zvakadzikama: BCC (BPF Compiler Unganidzo) raibhurari uye chishandiso chekugadzira BPF yekutsvagisa uye kugadzirisa zvirongwa, eBPF rutsigiro mu tc (Traffic Kudzora) yekumisikidza mapaketi uye kugadzirisa mitsara inopinda uye inobuda. Iyo bpftrace uye eXpress Dhata Path (XDP) zvikamu zvinoramba zviri muTechnical Preview nhanho.

Mifananidzo yekumisikidza haisati yaumbwa parizvino, asi zvakavimbiswa kuti vachave vakagadzirira svondo rinouya kweiyo x86_64, s390x (IBM System z), ppc64le uye Aarch64 zvivakwa.

Kana iwe uchida kuziva zvakawanda nezvazvo, iwe unogona kutarisa iyo ruzivo Mune inotevera chinongedzo.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
