Please solve and show work. Thank you. Assume val is an atomic integer in a Linux system. What is the value of val after the following operations have been completed? atomic set(&val,10); atomic sub(8,&val); atomic inc(&val); atomic inc(&val); atomic add(6,&val); atomic sub(3,&val); Show your work (Clearly outline the results of the implementation of each statement)
The security research group, Last Stage of Delirium, wrote some clean portbinding shellcode for Linux. Clean shellcode is shellcode that does not containNULL characters. NULL characters, as mentioned earlier, cause most bufferoverflow vulnerabilities to not be triggered correctly since the function stopscopying when a NULL byte is encountered.
The purpose of this assignment is to learn to develop multi-process programs. You are expected to extend the myshell.c program and add pipelines and I/O redirections. In particular, your shell program should recognize the following: > - Redirect standard output from a command to a file. Note: if the file already exists, it will be erased and overwritten without warning. For example, COP4338$ ls > 1COP4338$ sort myshell.c > 2Note that you're not supposed to implement the Unix commands (ls, sort, ...). You do need to implement the shell that invoke these commands and you need to "wire" up the standard input and output so that they "chain" up as expected. >> - Append standard output from a command to a file if the file exists; if the file does not exist, create one. For example, COP4338$ sort myshell.c >> 1COP4338$ echo "Add A Line" >> 1< - Redirect the standard input to be from a file, rather than the keyboard. For example, COP4338$ sort <…
The original Linux developers built a non-preemptible kernel for whatever reason.What good does it do to have a non-preemptible kernel in a single-processor computer? However, with a system with several processors, why does this benefit decrease?
