Oracle e lokolitse Unbreakable Enterprise Kernel R5U4

Khampani ea Oracle lokollotsoe ntlafatso ea bone ea ts'ebetso bakeng sa kernel Enterprise Kernel R5, e behiloeng bakeng sa tšebeliso ea Oracle Linux e le mokhoa o mong oa sephutheloana se tloaelehileng le kernel ho tsoa ho Red Hat Enterprise Linux. Kernel e fumaneha bakeng sa meralo ea x86_64 le ARM64 (aarch64). Mehloli ea kernel, ho kenyelletsa le karohano ea li-patches ka bomong, phatlalalitsoe sebakeng sa polokelo ea sechaba sa Oracle Git.

Sephutheloana sa Unbreakable Enterprise Kernel 5 se thehiloe holim'a kernel Linux 4.14 (UEK R4 e ne e ipapisitse le 4.1 kernel, le UEK R6 ka 5.4), e tlatselletsoang ka likarolo tse ncha, ntlafatso le litokiso, hape e lekoa bakeng sa ho lumellana le lits'ebetso tse ngata tse sebetsang ho RHEL, 'me e ntlafalitsoe ka ho khetheha ho sebetsa le software ea indasteri le lisebelisoa tsa Oracle. Ho kenya le liphutheloana tsa src ka kernel ea UEK R5U4 lokisitsoe bakeng sa Oracle Linux 7 (ha ho na litšitiso ho sebelisa kernel ena liphetolelong tse tšoanang tsa RHEL, CentOS le Scientific Linux).

Senotlolo ntlafatso:

• Tšehetso e ekelitsoeng bakeng sa ho boloka mekhahlelo ea sebaka sa aterese ea sebele ea ts'ebetso (Process Virtual Address Space Reservation), e lumellang ho eketsa botsitso ba Oracle DBMS ha sebaka sa aterese sa randomization (ASLR) se khoneha.
• Litokiso le lintlafatso tsa NFS tse amanang le phihlello ea cache ea leqephe, ts'ebetso ea mehala ea RPC, le ts'ehetso ea bareki ba NFSv4 li fetisitsoe ho tsoa ho litokollo tsa morao-rao tsa kernel ea mantlha. Mathata a NFS a fetang OCSF2 a rarollotsoe.
• Lisebelisoa tsa tlhahlobo ea li-stack tsa TCP li ekelitsoe, ts'ehetso ea lintlha tse thehiloeng ho eBPF e kentsoe, 'me ho ts'oaroa holimo ho fokotsoe.
• Li-patches tse ncha li fetisitsoe ho tloha kernel 5.6 ho sireletsa khahlanong le bofokoli ba sehlopha sa Specter v1.
• Bakhanni ba lisebelisoa ba ntlafalitsoe, ho kenyelletsa le mefuta e mecha ea mokhanni oa BCM573xx (bnxt_en), Intel Ethernet Switch Host Interface (fm10k), Intel Ethernet Connection XL710 (i40e), Broadcom MegaRAID SAS (megaraid_sas), LSI MPT Fusion SAS 3.0 (mpt3sas), Fiber Channel HBA (qla2xxx), Microsemi Smart Family Controller (smartpqi), Intel Volume Management Device (vmd) le Mware Virtual Machine Communication Interface (vmw_vmci).
