I-Oracle ikhiphe isibuyekezo sesihlanu sokusebenza se-Unbreakable Enterprise Kernel R5, ebekwe endaweni ezosetshenziswa ekusabalaliseni i-Oracle Linux njengenye indlela yephakheji evamile ene-kernel evela kuRed Hat Enterprise Linux. I-kernel iyatholakala kuma-architectures we-x86_64 kanye ne-ARM64 (aarch64). Imithombo ye-kernel, okuhlanganisa ukuhlukaniswa kweziqephu ngazinye, kushicilelwa endaweni yokugcina ye-Oracle Git yomphakathi.
I-Unbreakable Enterprise Kernel 5 isekelwe ku-Linux kernel 4.14 (i-UEK R4 yayisekelwe ku-kernel 4.1, futhi i-UEK R6 yayisekelwe ku-5.4), ebuyekezwe ngezici ezintsha, ukuthuthukiswa nokulungiswa, futhi ihlolwe ukuhambisana nezinhlelo zokusebenza eziningi. isebenza ku-RHEL futhi ilungiselelwe ngokukhethekile ukusebenza nesofthiwe yezimboni ne-Oracle hardware. Ukufakwa kanye namaphakheji we-src ane-UEK R5U5 kernel alungiselelwa i-Oracle Linux 7 (azikho izithiyo ekusebenziseni le kernel kuzinguqulo ezifanayo ze-RHEL, i-CentOS ne-Scientific Linux).
Ukuthuthukiswa Okubalulekile:
- Ikhodi enesibopho sokusula inqolobane yekhasi lememori ku-hypervisor ye-KVM ithuthukisiwe, okuthuthukise ukusebenza kwamasistimu amakhulu wezihambeli futhi kwanciphisa isikhathi sazo sokuqalisa.
- Iziphazamisi zilungisiwe futhi kwenziwe ukuthuthukiswa kukhodi ye-btrfs, CIFS, ext4, NFS, OCFS2 kanye nezinhlelo zefayela le-XFS.
- I-RDMA ithuthukise ukusebenza kwe-RDS (Reliable Datagram Sockets) amaswishi e-failover/failback uma kwenzeka ukwehluleka. Kwengezwe amathuluzi amasha okususa iphutha e-RDS enza ukulandela ngomkhondo kusetshenziswa i-eBPF ne-DTrace.
- Isixhumi esibonakalayo /sys/kernel/security/lockdown sengezwe kuma-securityfs ukuphatha imodi yokuvala i-Secure Boot lockdown, ekhawulela ukufinyelela komsebenzisi ku-kernel futhi ivimbe izindlela zokudlula i-UEFI Secure Boot.
- Izishayeli zedivayisi zibuyekeziwe, okuhlanganisa izinguqulo ezintsha zabashayeli be-LSI MPT Fusion SAS 3.0, BCM573xx, Intel QuickData, Intel i10nm EDAC, Marvell PHY, Microsoft Hyper-V kanye ne-QLogic Fiber Channel HBA.
