The in-kernel dynamic tracing mode uses the JTAG interface to ``hot-patch'' the system calls at runtime, injecting introspection code. This mode is more transparent than emulator based approaches, but assumes that the traced program does not have access to the kernel memory where the introspection code is loaded.
Tracing the User Space and Operating System Interactions
https://www.linux.com/training-tutorials/tracing-user-space-and-operating-system-interactions/
Tracing System Calls with strace. strace traces both directions of the interaction between the kernel and the evaluated application, namely, it traces when an application executes a system call, and when the operating system sends a signal to the process. In its simplest form, strace runs the application passed in the command line and prints ...

The write() system calls writes the data from a user buffer into a device such as a file. This system call is one of the ways to output data from a program. In general, the write system calls takes three arguments i.e. file descriptor, pointer to the buffer where data is stored and number of bytes to write from the buffer. close()

• Sys-call delegated to an agent that decides if call is allowed –Can be done without changing app (requires an emulation layer in monitored process) • Incorrect state syncing will not result in policy violation • What should agent do when app calls execve? – Process can make the call directly. Agent loads new policy file.

You've chosen the wrong syscall number. Take a look at how the kernel checks the syscall number limits here. For example (x86, 32bit): 496 ENTRY (system_call) 497 RING0_INT_FRAME # can't unwind into user space anyway 498 pushl_cfi %eax # save orig_eax 499 SAVE_ALL 500 GET_THREAD_INFO (%ebp) 501 # system call tracing in operation / …

system_call. 我们的system_call代码如上所述。 有实际开发经验的人都知道，在操作系统上运行的某个应用程序，如果想完成一些实际有用的功能，必然会用到操作系统提供的接口，这些接口被称为系统调用（System Call）。
