The target program (stack-L4) in this task is similar to the one in the Level 2, except that the buffer size is extremely small. We set the buffer size to 10, while in Level 2, the buffer size is much larger. Your goal is the same: get the root shell by attacking this Set-UID program. You may encounter additional challenges in this attack due to the small buffer size. If that is the case, you need to explain how your have solved those challenges in your attack.

3 Malloc—Dynamic Memory Allocation 1. Give an example where a malloc()-like allocator would fail due to external fragmentation. 2. Give an example where returning a block to the allocator results in reducing the number of free blocks. Assume an implicit free list is used.
Develop a C/C++ program that accepts the name of a memory trace file as a command line argument. Use the data to simulate a set associative cache using LRU replacement. Additional command line arguments will be needed to identify the details of the simulated cache. The arguments should appear in the following order: the memory trace input file X, where 2X == the number of direct-mapped sets Y, where 2Y == the number of blocks per set Z, where 2Z == the number of cached words per block Your program (say it's a compiled C program) could be run like this: ./cache data.tra 3 2 4 This would simulate an 8 set associative LRU cache with 4 blocks per set, where each block caches 16 addresses. NOTE… the reason I've chosen to use exponents for arguments is to ensure we have powers of 2 for everything. Trace File The trace file is line based with each line containing a memory address requested, in hex. Please note this data is real, so the addresses are larger than 32-bits. In…
(T/F) In dynamic relocation, the base and bounds values are part of the process state. (Y/N) In base and bounds addressing, can the base and bounds values for a process change during the lifetime of a process? If a process attempts to access a memory location outside its own virtual address space, what is the result? 1) a trap 2) an exception (T/F) A user process can change its own base and bounds values. Suppose we are using base and bounds addressing. If the virtual address is 5321, the base register value is 100, and the bounds register value is 4500, then what is the corresponding physical address. (The values given are decimal values.)
Note: Write a bash script to simulate producer-consumer problem using semaphores. Producer-consumer problem is a common paradigm for cooperating processes. A producer process produces information that is consumed by a consumer process. One solution to the producer-consumer problem uses shared memory. To allow producer and consumer processes to run concurrently, there must be available a buffer of items that can be filled by the producer and emptied by the consumer. This buffer will reside in a region of memory that is shared by the producer and consumer processes. A producer can produce one item while the consumer is consuming another item. The producer and consumer must be synchronized, so that the consumer does not try to consume an item that has not yet been produced.
“Prefetching” is a technique that leverages predictable address patterns to speculatively bring in additional cache blocks when a particular cache block is accessed. One example of prefetching is a stream buff er that prefetches sequentially adjacent cache blocks into a separate buff er when a particular cache block is brought in. If the data is found in the prefetch buff er, it is considered as a hit and moved into the cache and the next cache block is prefetched. Assume a two-entry stream buff er and assume that the cache latency is such that a cache block can be loaded before the computation on the previous cache block is completed. What is the miss rate for the address stream above?Cache block size (B) can aff ect both miss rate and miss latency. Assuming a 1-CPI machine with an average of 1.35 references (both instruction and data) per instruction, help find the optimal block size given the following miss rates for various block sizes. 8: 4% 16: 3% 32: 2% 64: 1.5% 128: 1%…
Implement and demonstrate a disk-based buffer pool class based on the LRU buffer pool replacement strategy. Disk blocks are numbered consecutively from the beginning of the file with the first block numbered as 0. Assume that blocks are 4096 bytes in size. Use the supplied C++ files to implement your LRU Buffer Pool based on the instructions below. Implement a BufferBlock class using the supplied BufferBlockADT.h Your Buffer Block must inherit BufferBlockADT or you will not get credit for your work. All BufferBlockADT virtual functions must be implemented in BufferBlock Block Size: 4096 bytes Add an instance variable to your buffer block implementation to store the block id; i.e., “int blockID.” Implement a Buffer Pool by inheriting BufferPoolADT (BufferPoolADT.h) – implement all of BufferPoolADT’s functions Your buffer pool should consist of 5 buffer blocks Your buffer pool should manage the buffers using the LRU strategy Your buffer pool should be named LRUBufferPool and…
Assume that a virtual memory is managed using a buffer pool. The buffer pool contains five buffersand each buffer stores one block of data. Memory accesses are bydiskblock ID. Assume thefollowing series of memory accesses takes place: 5 2 5 1 2 3 6 5 9 3 2 4 1 5 9 8 1 5 3 7 2 5 9 1 0 4 6 8 5. For each of the following buffer pool replacement strategies, show the contents of the buffer poolat the end of the series, and indicate how many times a block was found in the buffer pool (insteadof being readinto memory). Assume that the buffer pool is initially empty. a. First in, first out. b. Least frequently used (with counts kept only for blocks currently in memory, counts for a pageare lost when that page is removed, and the oldest item with smallestcount is removed whenthere is a tie). c. Least frequently used (with counts kept for all blocks, and the oldest item with the smalles d.Least recently used
I need justify and explain briefly in at least 3 sentences the complexity of each operation in buffer operations in terms of Big O notation of the below code: struct Node { char data; struct Node *next; }; struct Node* head1 = NULL; struct Node* head = NULL; void push(struct Node** head_ref, char new_data) { struct Node* new_node = (struct Node*) malloc(sizeof(struct Node)); new_node->data = new_data; new_node->next = (*head_ref); (*head_ref) = new_node; } void print_list(struct Node* Head) { printf("values are: "); while(Head) { printf("%c ", Head->data); Head = Head->next; } printf("\n"); } bool isEmpty() { return head == NULL; } void pop(struct Node **head_ref, int position) { // If linked list is empty if (*head_ref == NULL) return; // Store head node struct Node* temp = *head_ref; // If head needs to be removed if (position == 0) { *head_ref = temp->next; // Change head…
Please write in C/C++Write a program that spawn 2 thread: a producer and a consumer The producer thread MUST open an input file and repeatedly copy values to a CIRCULAR BUFFER The consumer should open an output file and repeatedly copy values from the same circular buffer to the file. If the producer is unable to write to the buffer (because it does not contain enough empty elements), or if the consumer is unable to read from the buffer (because it does not contain enough unread items), then it should proceed to the next iteration, choosing a new random number of bytes to copy.
Implementation of a Disk-based Buffer Pool A buffer pool is an area of main memory that has been allocated for the purpose of caching datablocks as they are read from disk. The main purpose of a buffer pool is to minimize disk I/O.Tasks: Implement a disk-based buffer pool application based on the below three buffer poolreplacement schemes: FIFO (first in, first out), LRU (least recently used), and LFU (Leastfrequently used) buffer pool replacement strategies.FIFO (First In, First Out): the oldest data block in the buffer pool is replaced.LRU (Least Recently Used): the least recently accessed data block in the buffer pool is replaced.LFU (Least Frequently Used): the least frequently accessed data block in the buffer pool isreplaced.Initially, the buffer pool is free. Disk blocks are numbered consecutively from the beginning ofthe file with the first block numbered as 0. When I execute your program,First, it asks the user to input the following parameters:o ?: number of blocks in the…
On a 32-bit processor, a baggy bounds scheme is expected to set all of the bounds table entries to 31 at initialization time. Assume that a buggy implementation with a slot size of 32 bytes performs bounds table initialization inappropriately, resulting in random entries being incorrectly set to 1. Assume that a networked server processes network messages using an uninstrumented library. Assume that this library does not include some buffer overflow bugs (i.e., it never calls unsafe functions such as gets()). However, the server suffers from the above-mentioned bounds table initialization issue, and an attacker may submit messages to the server that force the library to dynamically assign and write memory in an attacker-controlled amount using uninstrumented code that looks like this: / N is the size of the buffer that the intruder gets to choose.for (int I = 0; I N/4; i++, p += 4) char *p = malloc(N); *p = 'a'; *(p+1) = 'b'; *(p+2) = 'c'; *(p+3) = 'd'; Assume the server is using a…
