Oracle tau tshaj tawm Unbreakable Enterprise Kernel R5U4

Oracle tuam txhab tso tawm thib plaub ua haujlwm hloov tshiab rau lub kernel Unbreakable Enterprise Kernel R5, positioned rau siv nyob rau hauv lub Oracle Linux faib raws li ib tug lwm txoj rau cov txheej txheem pob nrog lub ntsiav los ntawm Red Hat Enterprise Linux. Lub kernel muaj rau x86_64 thiab ARM64 (aarch64) architectures. Kernel qhov chaw, suav nrog kev tawg mus rau hauv ib tus neeg thaj ua rau thaj, luam tawm hauv Oracle public Git repository.

Lub Unbreakable Enterprise Kernel 5 pob yog raws li cov ntsiav Linux 4.14 (UEK R4 yog raws li 4.1 ntsiav, thiab UA R6 ntawm 5.4), uas yog ntxiv nrog cov yam ntxwv tshiab, kev ua kom zoo dua qub thiab kho, thiab tseem raug sim rau kev sib raug zoo nrog feem ntau cov ntawv thov khiav ntawm RHEL, thiab tshwj xeeb tshaj yog ua kom zoo rau kev ua haujlwm nrog software thiab Oracle hardware. Kev teeb tsa thiab src pob nrog UEK R5U4 kernel npaj rau Oracle Linux 7 (tsis muaj teeb meem rau kev siv cov ntsiav no hauv cov qauv zoo sib xws ntawm RHEL, CentOS thiab Scientific Linux).

Ntsiab kev txhim kho:

• Ntxiv kev txhawb nqa rau kev tshwj tseg ntawm qhov chaw nyob virtual ntawm cov txheej txheem (Cov Txheej Txheem Virtual Chaw Nyob Chaw Nyob), uas tso cai rau kom muaj kev ruaj ntseg ntawm Oracle DBMS thaum chaw nyob qhov chaw randomization (ASLR) tau qhib.
• Kho thiab optimizations rau NFS ntsig txog nplooj ntawv cache nkag, RPC hu ua, thiab NFSv4 tus neeg siv kev txhawb nqa tau nqa los ntawm kev tshaj tawm tsis ntev los no ntawm cov ntsiav tseem ceeb. Cov teeb meem nrog NFS khiav dhau OCSF2 tau raug daws.
• TCP pawg tshuaj ntsuam xyuas cov cuab yeej tau nthuav dav, kev txhawb nqa rau eBPF-raws li cov ntsiab lus tau raug ntxiv, thiab kev taug qab cov nyiaj siv ua haujlwm tau raug txo.
• Cov thaj ua rau thaj tshiab tau raug pauv los ntawm ntsiav 5.6 los tiv thaiv Spectre v1 chav kawm tsis muaj zog.
• Cov cuab yeej tsav tsheb tau raug hloov kho, suav nrog cov tsav tsheb tshiab rau BCM573xx (bnxt_en), Intel Ethernet Hloov Tus Tswv Cuab Interface (fm10k), Intel Ethernet Connection XL710 (i40e), Broadcom MegaRAID SAS (megaraid_sas), LSI MPT Fusion SAS 3.0 (mpt3sas), QLog Fiber Channel HBA (qla2xxx), Microsemi Smart Family Controller (smartpqi), Intel Volume Management Device (vmd) thiab Mware Virtual Machine Communication Interface (vmw_vmci).
