Contrairement \u00e0 d'autres outils de d\u00e9veloppement de programmes eBPF, Aya ne s'appuie pas sur libbpf et le compilateur bcc, mais propose sa propre impl\u00e9mentation, \u00e9crite en Rust, qui utilise le paquet crate libc pour un acc\u00e8s direct aux appels syst\u00e8me du noyau. Aucun outil de d\u00e9veloppement C et aucun fichier d'en-t\u00eate du noyau ne sont n\u00e9cessaires pour compiler Aya. Le code de la biblioth\u00e8que est distribu\u00e9 sous les licences MIT et Apache 2.0.    <\/p>\n<p>Fonctionnalit\u00e9s principales :  <\/p>\n<ul>\n<li class=\"l\"> Prise en charge du format BTF (BPF Type Format), qui fournit des informations de type dans du pseudocode BPF pour la v\u00e9rification de types et la correspondance avec les types fournis par le noyau actuel. L'utilisation de BTF permet de cr\u00e9er des gestionnaires eBPF universels pouvant \u00eatre utilis\u00e9s sans recompilation avec diff\u00e9rentes versions du noyau Linux.\n<li class=\"l\"> Support for 'bpf-to-bpf' calls, global variables, and initializers, allowing the design of eBPF programs similarly to regular programs using aya as a runtime, overriding functions based on the operation in eBPF.\n<li class=\"l\"> Prise en charge de divers types de noyaux, notamment des tableaux ordinaires, des hachages (hash map), des piles, des files d'attente, des tra\u00e7ages de pile, ainsi que des structures pour les sockets et le suivi des performances.\n<li class=\"l\"> Possibilit\u00e9 de cr\u00e9er divers types de programmes eBTF, y compris des programmes pour le filtrage et la gestion du trafic, des gestionnaires de cgroup et diverses op\u00e9rations sur les sockets, des programmes XDP.\n<li class=\"l\"> Prise en charge des plateformes pour le traitement asynchrone des requ\u00eates en mode non-bloquant tokio et async-std.\n<li class=\"l\"> Compilation rapide, sans d\u00e9pendance \u00e0 la compilation du noyau et aux fichiers d'en-t\u00eate du noyau.    <\/ul>\n<p>The project is still considered experimental \u2014 the API is not yet stabilized and continues to evolve. Not all intended features have been implemented. By the end of the year, developers expect to bring Aya's functionality to parity with libbpf, and in January 2022, to produce the first stable release. It is also planned to combine parts of Aya necessary for writing code in Rust for the Linux kernel with components that operate in user space and are used for loading, attaching, and interacting with eBPF programs.   <\/p>\n<p>Rappelons que l'eBPF est un interpr\u00e9teur de bytecode int\u00e9gr\u00e9 au noyau Linux, permettant de cr\u00e9er des gestionnaires d'op\u00e9rations r\u00e9seau, de surveiller le fonctionnement des syst\u00e8mes, d'intercepter des appels syst\u00e8me, de contr\u00f4ler l'acc\u00e8s, de traiter des \u00e9v\u00e9nements tout en conservant le chronom\u00e9trage, de compter la fr\u00e9quence et le temps d'ex\u00e9cution des op\u00e9rations, d'effectuer des traces \u00e0 l'aide de kprobes\/uprobes\/tracepoints. Gr\u00e2ce \u00e0 l'utilisation de la compilation JIT, le bytecode est traduit \u00e0 la vol\u00e9e en instructions machine et ex\u00e9cut\u00e9 avec la performance d'un code natif. XDP fournit des moyens pour ex\u00e9cuter des programmes BPF au niveau du pilote r\u00e9seau, offrant un acc\u00e8s direct au buffer DMA des paquets, ce qui permet de cr\u00e9er des gestionnaires \u00e0 haute performance pour fonctionner dans des conditions de charge r\u00e9seau \u00e9lev\u00e9e.<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=55340\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u043f\u0435\u0440\u0432\u044b\u0439 \u0432\u044b\u043f\u0443\u0441\u043a \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0438 Aya, \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0435\u0439 \u0441\u043e\u0437\u0434\u0430\u0432\u0430\u0442\u044c \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 Rust \u043e\u0431\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u0438 eBPF, \u0437\u0430\u043f\u0443\u0441\u043a\u0430\u0435\u043c\u044b\u0435 \u0432\u043d\u0443\u0442\u0440\u0438 \u044f\u0434\u0440\u0430 Linux \u0432 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u043e\u0439 \u0432\u0438\u0440\u0442\u0443\u0430\u043b\u044c\u043d\u043e\u0439 \u043c\u0430\u0448\u0438\u043d\u0435 \u0441 JIT. \u0412 \u043e\u0442\u043b\u0438\u0447\u0438\u0435 \u043e\u0442 \u0434\u0440\u0443\u0433\u0438\u0445 \u0438\u043d\u0441\u0442\u0440\u0443\u043c\u0435\u043d\u0442\u043e\u0432 \u0434\u043b\u044f \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 eBPF-\u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c, Aya \u043d\u0435 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442 libbpf \u0438 \u043a\u043e\u043c\u043f\u0438\u043b\u044f\u0442\u043e\u0440 bcc, \u0430 \u043f\u0440\u0435\u0434\u043b\u0430\u0433\u0430\u0435\u0442 \u0441\u043e\u0431\u0441\u0442\u0432\u0435\u043d\u043d\u0443\u044e \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u044e, \u043d\u0430\u043f\u0438\u0441\u0430\u043d\u043d\u0443\u044e \u043d\u0430 Rust, \u043a\u043e\u0442\u043e\u0440\u0430\u044f \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442 crate-\u043f\u0430\u043a\u0435\u0442 libc \u0434\u043b\u044f \u043f\u0440\u044f\u043c\u043e\u0433\u043e \u043e\u0431\u0440\u0430\u0449\u0435\u043d\u0438\u044f \u043a \u0441\u0438\u0441\u0442\u0435\u043c\u043d\u044b\u043c \u0432\u044b\u0437\u043e\u0432\u0430\u043c \u044f\u0434\u0440\u0430.
