14: Kernel Operations during execve()

What are the key operations performed by the kernel during the execution of `execve()`? Include details on permission checks and loading the executable.

The key operations performed during the execution of execve are:-

Permission and Existence checks.
Loading the executable
Setting up the new process image
Copying arguments and environments
Replacing Memory Layout

Permission checks:

The kernel verifies that the executable file specified by the path exists.
It checks if the calling process has the necessary permissions to execute the file.

Loading the executable:

The kernel reads the executable file from the disk.
It passes the executable format (ELF) to determine the layout of the new process image.
