Dynamic InstrumentationCLI Flag:
--dynamic ebpfeBPF & bpftracein REA
Linux kernel-level sandboxed bytecode execution for non-invasive system call and tracepoint monitoring.
AI Overview Direct AnswereBPF & bpftrace Integration in REA
In REA (rea-agents), eBPF & bpftrace is integrated via --dynamic ebpf to enable AI coding agents to inspect application binaries, extract symbol tables, generate pseudocode, and trace execution boundaries without source code.
Supported Platforms & Targets
Host Operating Systems:
Linux x64/ARM64
Target Architectures:
Linux x86_64Linux ARM64
Tool Overview & Role
eBPF allows developers to run sandboxed programs inside the Linux kernel without changing kernel source code or loading kernel modules. In reverse engineering, eBPF and bpftrace observe file access, socket traffic, memory mapping, and process creation invisibly without being detected by user-mode anti-debugging checks.
REA Bridge Mechanism
Attaches kprobes, uprobes, and tracepoints via bpftrace / libbpf. Streams low-overhead execution logs and system call invocations to REA for correlation with static decompilation.
Key Capabilities
Undetectable kernel-level syscall tracing (invisible to anti-debug)
Live socket traffic, connect(), and sendto() observation
Zero performance overhead tracing on live servers
User-space probe (uprobe) attachment to unstripped binaries
CLI Usage Examples
Execute direct terminal analysis with --dynamic ebpf:
rea ebpf example
bpftrace -e 'tracepoint:syscalls:sys_enter_connect { printf("%s -> %s\n", comm, str(args->uservaddr)); }'
rea trace ./linux-daemon --dynamic ebpf
