Konstantin Ryabtsev, administrateur de l'infrastructure kernel.org, a publi\u00e9 les r\u00e9sultats d'une analyse du trafic du service git.kernel.org, qui permet de consulter le contenu des d\u00e9p\u00f4ts git des projets li\u00e9s au d\u00e9veloppement du noyau Linux. Chaque jour, le service traite environ 6 millions de requ\u00eates d'informations sur les commits, dont 66 % proviennent de bots que l'on parvient \u00e0 bloquer gr\u00e2ce au syst\u00e8me Anubis. 33 % des requ\u00eates passent par le syst\u00e8me Anubis, qui n'autorise l'acc\u00e8s qu'apr\u00e8s avoir trouv\u00e9 en JavaScript une valeur dont le hachage SHA-256, combin\u00e9 avec une cha\u00eene fournie par le serveur, comporte un certain nombre de z\u00e9ros initiaux (cette t\u00e2che n\u00e9cessite des ressources CPU pour \u00eatre r\u00e9solue, mais pas pour la v\u00e9rification). <\/p>\n

Il est impossible de d\u00e9terminer exactement qui parmi ces 33 % sont des humains et qui sont des bots avanc\u00e9s, mais en raison de la nature des requ\u00eates, on conclut que la part totale des requ\u00eates l\u00e9gitimes est d'environ 2 %, tandis que les 98 % restants concernent des scrapers. L'une des caract\u00e9ristiques des bots est de faire des requ\u00eates directes sur d'anciens commits dans des branches anciennes au hasard, ce qui est peu probable qu'il soit n\u00e9cessaire pour les humains dans leur travail. L'activit\u00e9 des bots g\u00e9n\u00e8re une \u00e9norme surcharge parasite sur serveurs<\/a> plut\u00f4t que de t\u00e9l\u00e9charger une seule fois tout le code et l'historique des commits via l'op\u00e9ration «git clone», les bots envoient des milliards de requ\u00eates, explorant toutes les options d'acc\u00e8s via l'interface web et demandant \u00e0 plusieurs reprises les m\u00eames donn\u00e9es avec diff\u00e9rents param\u00e8tres. <\/p>\n

Le blocage des bots par adresses IP<\/a> et syst\u00e8mes autonomes a rapidement cess\u00e9 de fonctionner, car les bots ont commenc\u00e9 \u00e0 envoyer des requ\u00eates depuis des millions d'adresses IP al\u00e9atoires provenant de r\u00e9seaux domestiques ou mobiles, obtenues gr\u00e2ce \u00e0 l'activit\u00e9 de botnets ou \u00e0 la mon\u00e9tisation d'extensions de navigateur. Depuis chaque adresse, seulement 4 \u00e0 5 requ\u00eates sont envoy\u00e9es, il est donc inutile de les bloquer au niveau du pare-feu. <\/p>\n

Pendant un certain temps, le syst\u00e8me Anubis a aid\u00e9 \u00e0 bloquer les bots, mais avec le temps, les bots se sont adapt\u00e9s pour r\u00e9aliser les calculs propos\u00e9s dans Anubis. Parmi d'autres, les bots ont appris \u00e0 r\u00e9soudre des probl\u00e8mes de niveau 5 de difficult\u00e9, et il devient difficile d'augmenter le niveau car m\u00eame le cinqui\u00e8me niveau n\u00e9cessite plusieurs secondes de calcul, ce qui agace fortement les utilisateurs l\u00e9gitimes. <\/p>\n

En fin de compte, le traitement des requ\u00eates des scrapers dans l'infrastructure kernel.org n\u00e9cessite plus de ressources que toutes les autres op\u00e9rations l\u00e9gitimes, y compris «git clone». serveurs<\/a>, servant git.kernel.org, \u00e0 tout moment, 14-16 des 90 c\u0153urs CPU disponibles sont constamment occup\u00e9s \u00e0 afficher les commits git pour les bots. Afin de r\u00e9duire la charge, les administrateurs essaient d\u00e9sormais de restreindre les capacit\u00e9s du service, de d\u00e9sactiver certaines op\u00e9rations gourmandes en ressources, de limiter l'acc\u00e8s anonyme et de r\u00e9duire le nombre de liens disponibles pour la navigation.
