Compania Solo.io, care dezvolt\u0103 produse pentru func\u021bionarea sistemelor cloud, microserviciilor, containerelor izolate \u0219i calculului serverless, a publicat un toolkit deschis numit BumbleBee, destinat simplific\u0103rii preg\u0103tirii, distribuirii \u0219i lans\u0103rii programelor eBPF, care sunt executate \u00eentr-o ma\u0219in\u0103 virtual\u0103 special\u0103 din interiorul nucleului Linux \u0219i permit procesarea opera\u021biunilor de re\u021bea, controlul accesului \u0219i monitorizarea func\u021bion\u0103rii sistemelor. Codul este scris \u00een limbajul Go \u0219i este distribuit sub licen\u021ba Apache 2.0. <\/p>\n

BumbleBee permite ambalarea programului eBPF sub forma unei imagini de container \u00een format OCI (Open Container Initiative), care poate fi rulat\u0103 pe orice sistem f\u0103r\u0103 recompilare \u0219i utilizarea componentelor suplimentare \u00een spa\u021biul utilizatorului. Interac\u021biunea cu codul eBPF din nucleu, inclusiv procesarea datelor primite de la handlerul eBPF, este gestionat\u0103 de BumbleBee, care export\u0103 automat aceste date sub form\u0103 de metrici, histograme sau loguri, la care se poate accesa, de exemplu, folosind utilitarul curl. Abordarea propus\u0103 permite dezvoltatorului s\u0103 se concentreze pe scrierea codului eBPF \u0219i s\u0103 nu fie distras de organizarea interac\u021biunii cu acest cod din spa\u021biul utilizatorului, compilarea \u0219i \u00eenc\u0103rcarea \u00een nucleu. <\/p>\n

Pentru gestionarea programelor eBPF, se propune o utilitar\u0103 de tip Docker numit\u0103 «bee», cu ajutorul c\u0103reia se poate \u00eenc\u0103rca imediat handlerul eBPF de interes dintr-un repository extern \u0219i rula pe sistemul local. Instrumentul permite generarea unei structuri de cod \u00een C pentru handlerii eBPF pe o tem\u0103 aleas\u0103 (\u00een prezent, sunt suportate doar handlerii pentru opera\u021biuni de re\u021bea \u0219i fi\u0219iere, care intercept\u0103 apelurile din stiva de re\u021bea \u0219i sistemele de fi\u0219iere). Pe baza structurii generate, dezvoltatorul poate implementa rapid func\u021bionalitatea dorit\u0103. <\/p>\n

Spre diferen\u021b\u0103 de BCC (BPF Compiler Collection), BumbleBee nu efectueaz\u0103 recompilarea complet\u0103 a codului handler-ului pentru fiecare versiune a nucleului Linux (BCC folose\u0219te compilarea \u00een timp real cu Clang la fiecare rulare a programului eBPF). Pentru a rezolva problemele de portabilitate, se dezvolt\u0103 instrumentele CO-RE \u0219i libbpf, care permit compilarea codului o singur\u0103 dat\u0103 \u0219i utilizarea unui \u00eenc\u0103rc\u0103tor universal special adaptat pentru nucleul curent \u0219i tipurile BTF (BPF Type Format). BumbleBee este un strat deasupra libbpf \u0219i ofer\u0103 tipuri suplimentare pentru interpretarea \u0219i af\u0219area automat\u0103 a datelor plasate \u00een structuri standard eBPF map, RingBuffer \u0219i HashMap. <\/p>\n

Pentru a construi programul final eBPF \u0219i a-l salva sub form\u0103 de imagine OCI, este suficient s\u0103 executa\u021bi comanda «bee build fi\u0219ier_cu_cod nume:versiune», iar pentru a rula, comanda «bee run nume:versiune». \u00cen mod implicit, evenimentele ob\u021binute de la handler vor fi afi\u0219ate \u00een fereastra terminalului, dar, dac\u0103 este necesar, se pot ob\u021bine date apel\u00e2nd utilitarii curl sau wget la portul de re\u021bea legat de handler. Handlerii pot fi distribui\u021bi prin repository-uri compatibile OCI; de exemplu, pentru a lansa un handler extern din repository-ul ghcr.io (GitHub Container Registry) se poate executa comanda «bee run ghcr.io\/solo-io\/bumblebee\/tcpconnect:$(bee version)». Pentru a plasa un handler \u00een repository se propune comanda «bee push», iar pentru a lega o versiune \u2014 «bee tag».
