In Linux, the parameters of an eBPF program are passed through the context struct of the BPF program. Within the eBPF program, various fields of the context struct can be accessed to retrieve the passed parameters. For example, in the eBPF program, parameters can be accessed by using fields like ctx->arg1, ctx->arg2, etc.

It is important to note that the parameters in eBPF programs are not passed according to traditional C function call conventions, but are instead passed through the context structure of the BPF program. Therefore, when writing eBPF programs, it is necessary to determine the form of the parameters and how to access these parameters based on the incoming context structure.
