Red Hat Enterprise Linux inozivikanwawo neacronym yayo RHEL kugovera kwekutengesa kweGNU/Linux kwakagadzirwa neRed Hat.
Red Hat ichangobva kuzivisa kuburitswa kwe yako Linux kugovera, "Red Hat Enterprise Linux 9.1", vhezheni iyo iyo RHEL 9 bazi rinoenderera mberi nekushanduka neyakavhurika nzira yekuvandudza uye inovaka pahwaro hweCentOS Stream 9 package.
CentOS Stream yakamisikidzwa seyepamusoro purojekiti yeRHEL, ichibvumira mapato echitatu kudzora kugadzirira kweRHEL mapakeji, kurudzira shanduko, uye kupesvedzera sarudzo. Zvinoenderana negumi-gore rekutsigira kutenderera kwekugovera, RHEL 10 ichachengetwa kusvika 9.
Chii Chitsva muRed Hat Enterprise Linux 9.1
Mune iyi vhezheni itsva inounzwa, inosimbiswa kuti SELinux yakagadziridzwa kune shanduro 3.4, iyo yave iri yakavandudzwa relabel performance (relabel) nekuda kwekufananidzwa kwekushanda, sarudzo «-m»(«--checksum") kune semodule yekushandisa kuti utore SHA256 hashes kubva kumamodule, mcstrans yaendeswa kuPCRE2 raibhurari. Pamusoro peizvi, SELinux marongero akawedzerwa kuchengetedza masevhisi ksm, nm-priv-helper, rhcd, stalld, systemd-network-generator, targetclid, uye wg-nekukurumidza.
Chimwe chitsva chinoratidzwa ndechekuti kugona kushandisa mutengi weClevis (clevis-luks-systemd) kuvhura otomatiki dhisiki zvikamu zvakavharidzirwa neLUKS uye yakasimudzwa pane imwe nguva yebhutsu, pasina chikonzero chekushandisa murairo "systemctl inogonesa clevis-luks-askpass.path".
Kugona kwekugadzirira system mifananidzo kwakawedzerwa, iyo zvino inotsigira kurodha mifananidzo kuGoogle Cloud Platform (GCP), ichiisa mufananidzo wacho zvakananga murejista yemidziyo, kuseta saizi ye / boot partition, uye tuning paramita (Blueprint) panguva yekufungidzira (semuenzaniso, pakuwedzera mapakeji nekugadzira vashandisi) .
Yakawedzerwa chinoshandiswa keylime yekupupurira (kutendeseka uye kuenderera mberi kwekutarisa kuvimbika) kweiyo yekunze sisitimu uchishandisa TPM (Trusted Platform Module) tekinoroji, semuenzaniso, kuratidza huchokwadi hweEdge neIoT zvishandiso zviri munzvimbo isingadzoreki uko kunowanikwa kusingatenderwe.
SSSD yakawedzera rutsigiro rwe caching SID zvikumbiro (semuenzaniso, GID/UID macheki) mu RAM, izvo zvakaita kuti zvikwanise kukurumidza kukopa mashandiro enhamba huru yemafaira kuburikidza neSamba server.
MuOpenSSH, saizi shoma shoma yemakiyi eRSA ndeye 2048 bits. uye maraibhurari eNSS haichatsigiri makiyi eRSA madiki pane 1023 bits. Iyo InodiwaRSasize parameter yakawedzerwa kuOpenSSH kuti uise yako miganhu. Yakawedzerwa tsigiro ye sntrup761x25519-sha512@openssh.com kiyi yekutsinhana nzira, iyo inoshingirira kurwiswa pamakomputa equantum.
iyo subsystemeBPF inotakura kuvandudzwa kwakaitwa muLinux 5.15 uye 5.16 kernels. Semuenzaniso, kune zvirongwa zveBPF, kugona kubvunza uye kugadzirisa zviitiko zvenguva, kugona kuwana uye kuseta socket sarudzo ku setsockopt, tsigiro yekufona kernel module mabasa, yekuchengetedza chimiro bloom sefa, probabilistic data (BPF mepu) uye kugona Wedzera ma tag ekusunga kumabasa paramita.
Izvo zvakare zvakasimbiswa izvo MPTCP protocol kuita yakagadziridzwa (MultiPath TCP), ichiwedzera rutsigiro rweMPTCP yekubatanidza yekudzokera kumashure kune TCP yakajeka uye ichipa API kubata MPTCP hova kubva munzvimbo yemushandisi).
Of the dzimwe shanduko dzinomira pachena yeiyi vhezheni itsva:
- Iyo chaiyo-nguva system chigamba seti inoshandiswa mu rt-kernel yakagadziridzwa kune iyo nyika inoenderana ne5.15-rt kernel.
- Pane masisitimu ane 64-bit ARM, AMD, uye Intel processors, kugona kushandura chaiyo-nguva modhi maitiro mu kernel panguva yekumhanya nekunyora iyo modhi zita kune iyo .
- Iyo GRUB bootloader gadziriso yakashandurwa kuti ivanze iyo default boot menyu, ichiratidza menyu kana bhutsu yapfuura ikatadza.
- Tsigiro yekugadzira chaiyo hardware wachi (PHC, PTP hardware wachi) yakawedzerwa kune PTP (Precision Time Protocol) mutyairi.
- Yakawedzera iyo modulesync yekuraira iyo inodhawunirodha module RPM mapakeji uye inogadzira repository mudhairekitori rekushanda ine metadata inodiwa kuisa module mapakeji.
- NetworkManager inoshandisa shanduro yekubatanidza profiles kubva ku ifcfg configuration format kusvika kune keyfile-based format.
- Mutyairi weIntel E800 Ethernet Adapter inotsigira iWARP neRoCE protocol.
Chekupedzisira, kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.

For the kufarira uye kuwana iyo Red Hat mutengi portal, iwe unofanirwa kuziva kuti iyi vhezheni yakagadzirirwa x86_64, s390x (IBM System z), ppc64le uye Aarch64 (ARM64) zvivakwa. Iwo masosi eRed Hat Enterprise Linux 9 rpm mapakeji ari muCentOS Git repository.
Yakagadzirirwa-yakagadzirwa yekuisa mifananidzo inowanikwa kune vakanyoreswa vashandisi veRed Hat Mutengi Portal (unogona zvakare kushandisa CentOS Stream 9 iso mifananidzo kuongorora kushanda).
