This article mainly introduces the relevant knowledge of how the linux program runs at the specified address, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this linux program how to run the article at the specified address. Let's take a look at it.

We know that the address of the program is different every time it runs, and the reason why linux has such a design may be for security reasons, which is not conducive to hackers' attacks.

Let's look at a simple program:

# include

# include

Int main (int argc, char* argv [])

{

Int first = 0

Int * p = malloc (1024)

Printf ("paired% p\ n", p)

Return 0

}

Obviously, the address of the program is different every time!

Is there any way to make the same program run at the same address every time?

When you see here, you may ask why you let the program run at the same address every time. Does this not go against the original intention of OS design? Yes, this does go against the original intention of the linux kernel design. However, it is inevitable that strange requirements will not be encountered in the actual project. For example, some app needs to be run on the specified address due to historical reasons, so you need to turn off the randomization of the address space. For example, if you encounter a random address crash problem, you can also use this method to debug.

To cut the crap, let's take a look at the way address space is randomized and turned off.

Echo 0 > / proc/sys/kernel/randomize_va_space

Or

Sudo sysctl-w kernel.randomize_va_space=0

After turning it off, let's take a look at the test results of the program:
