Microsoft on avaldanud eBPF alamkihi Windowsile, v\u00f5imaldades k\u00e4ivitada juhte, mis t\u00f6\u00f6tavad operatsioonis\u00fcsteemi tuumatasemel. eBPF tarjoaa sisseehitatud tuumainterpreteri, mis v\u00f5imaldab luua kasutajaruumi laaditavaid v\u00f5rguoperatsioonide k\u00e4sitlejaid, hallata juurdep\u00e4\u00e4su ja j\u00e4lgida s\u00fcsteemi toimimist. eBPF on kaasatud Linuxi tuuma alates versioonist 3.18 ning v\u00f5imaldab t\u00f6\u00f6delda sissetulevaid\/v\u00e4ljuvaid v\u00f5rgu pakette, suunata pakette, hallata ribalaiust, pealtkuulata s\u00fcsteemik\u00f5nesid, kontrollida juurdep\u00e4\u00e4su ja teostada j\u00e4lgimist. JIT-kompileerimise rakendamise t\u00f5ttu t\u00f5lgitakse bytecode reaalajas masinakeelde ja seda t\u00e4idetakse kompileeritud koodi j\u00f5udlusega. eBPF algkood Windowsile on avatud MIT litsentsi alusel. <\/p>\n

eBPF Windowsile saab kasutada juba olemasolevate eBPF t\u00f6\u00f6riistadega ja see pakub t\u00fc\u00fcpilist API-d, mida rakendatakse eBPF rakendustes Linuxis. Projekti kaudu on v\u00f5imalik kompileerida C keeles kirjutatud kood eBPF bytecode'iks, kasutades Clangi baasil p\u00f5hinevat eBPF kompilaatorit ja k\u00e4ivitada Linuxile loodud eBPF t\u00f6\u00f6tlusi Windowsi kernelis, pakkudes spetsiaalset \u00fchilduvuskihti ja toetades Libbpf API-d, et s\u00e4ilitada \u00fchilduvus rakendustega, mis suhtlevad eBPF programmidega. Samuti pakutakse kihi, mis annab Linuxi sarnased hook\u2019id XDP (eXpress Data Path) ja socket bind jaoks, abstraktsiat juurdep\u00e4\u00e4suks Windowsi v\u00f5rgu kihti ja v\u00f5rgu draiveritele. Tuleviku plaanides mainitakse t\u00e4iemahulise \u00fchilduvuse pakkumist l\u00e4htekooditasemel t\u00fc\u00fcpiliste eBPF t\u00f6\u00f6tlejatega Linuxis.

eBPF-i rakendamise peamine erinevus Windows'is seisneb alternatiivse baitkoodi kontrollija kasutamises, mille algselt pakkusid v\u00e4lja VMware t\u00f6\u00f6tajad ja Kanada ning Iisraeli \u00fclikoolide teadlased. Kontrollija k\u00e4ivitatakse eraldi isoleeritud protsessis kasutajaruumi andmev\u00e4ljas ning seda rakendatakse enne BPF-programmide t\u00e4itmist, et avastada vigu ja blokeerida v\u00f5imalikke pahatahtlikke tegevusi. <\/p>\n

Windowsi eBPF-s kasutatakse staatilise anal\u00fc\u00fcsi meetodit, mis p\u00f5hineb abstraktsel t\u00f5lgendusel (Abstract Interpretation), millel on v\u00f5rreldes Linuxi eBPF kontrollijaga madalam valepositiivide m\u00e4\u00e4r, see toetab ts\u00fcklite anal\u00fc\u00fcsi ja tagab hea skaleeritavuse. Meetod arvestab mitmeid t\u00fc\u00fcpilisi t\u00e4itmismustreid, mis on saadud olemasolevate eBPF-programmide anal\u00fc\u00fcsi p\u00f5hjal. <\/p>\n
