Intercept

Provides an abstraction to the kernel interface:
Run a binary and attach to it.
Callbacks for system calls:
intercept_register_sccb("native", "open", trans_cb, NULL);

Generic framework for system call argument translation.
intercept_register_transfn("native", "open", 0);
intercept_register_translation("native", "open", 1, &oflags);

System call argument replacement.
intercept_replace_init(&repl);
intercept_replace_add(&repl, tl->off, tl->trans_data, tl->trans_size);
[...]
intercept_replace(fd, pid, &repl);
