clj-ebpf.dsl.core

Core DSL module that re-exports all DSL functionality.

This namespace provides a unified API for BPF program construction:

(require '[clj-ebpf.dsl.core :as dsl])

;; Build a simple XDP program that drops all packets
(def drop-all
  (dsl/assemble
    [(dsl/mov :r0 1)    ; XDP_DROP = 1
     (dsl/exit-insn)]))

For more focused imports, use the submodules directly:

  • clj-ebpf.dsl.instructions - Low-level instruction encoding
  • clj-ebpf.dsl.alu - Arithmetic operations
  • clj-ebpf.dsl.mem - Memory operations
  • clj-ebpf.dsl.jump - Control flow
  • clj-ebpf.dsl.atomic - Atomic memory operations
