how to trace call from unknown number

Call Trace can print the current stack of function calls. kernel state Call Trace There are three types of error in the kernel state, namely bugs, oops and panic. Bugs are minor errors, such as calling sleep during spin_lock, causing a potential deadlock problem, and so on. Oops represents a user process error and need

Label:Lab Job: Make GDB Trace Parse a system call kernel function (I'm using Getuid) 20135313 Wu Ziyi. Beijing Institute of Electronic Technology "first part" according to the video demonstration steps, first part, the steps are as follows ① Updating the menu code to the latest version ② adding C functions and assembly functions to the Code ③ add Makeconfig to the main function ④make Rootfs ⑤ can see th

function backtrace_symbols FD , one per line. It does not use the malloc function, and can therefore is used in situations where the function might fail. The following program illustrates the use of these functions. Note that the array to contain the return addresses returned was backtrace allocated on the stack. Therefore code like this can is used in situations where the memory handling via malloc does don't work anymore (in which CAs E The have to is replaced by a

The example in this article describes the Android call stack trace method. Share to everyone for your reference. Specifically as follows: Android development, we also often encounter a segment error, that is, SIGSEGV (11), this time libc's backtrace will print out the corresponding stack information, and you see just a pair of numbers, it seems impossible to check. such as the following from a string faul

The usual way to see the function run-time stack is to use an external debugger such as GDB (BT command), but sometimes it is useful to print out the call stack of a function in case of a program error in order to parse the program's bug (mainly for long-running program analysis).In the glibc header file "Execinfo.h", three functions were declared to get the function call stack of the current thread.int bac

The cause of this is that the previous colleague's code had a memory pool where there was no recycling. That is, pop out of the object did not push back, the situation is difficult to reproduce, so in the pop print log, tracking is who called it, I think in the GDB debugging can be traced to the stack frame of the call, there must be a way to achieve. First search the internet for a bit, and no results! Fortunately, the amount of code is not many, onl
