Gadget limitations

This guide covers the known limitations of gadgets.

Uprobes on statically compiled binaries

Uprobe-based gadgets, such as trace_malloc, cannot trace statically compiled binaries. They also cannot trace binaries that invoke syscalls directly via syscall(syscall_id, ...), since this bypasses the standard C library wrappers that uprobes attach to.

Tracing I/O performed via io_uring

Gadgets that trace I/O operations, such as trace_open, rely on hooking individual syscalls (e.g., open()). These gadgets cannot observe operations submitted via io_uring, because io_uring bypasses the normal syscall entry path and dispatches requests directly within the kernel.
