Abstract
High-throughput BPF map manipulations with uprobes are disclosed. A method for manipulating a Berkeley Packet Filter (BPF) map comprises running a user program in a user space of a computing environment. The user program includes a trigger function. A corresponding kernel BPF probe is installed by the user program on the trigger function. The kernel BPF probe is triggered by reaching a memory address of the trigger function in the user space. The trigger function includes one or more arguments that the BPF map agent interprets as operation parameters. The BPF map agent performs one or more operations to manipulate a BPF map in the kernel space based on the operation parameters.
