Also, many hardware number generators have limited bandwidth, so it's natural for their output to be only used for seeding a random number generator.

Title: Stack Protection Support Description: This test verifies that stack canaries operate as expected. -------------------------------------------------------------------------------- Building and Running Project: This project outputs to the console. It can be built and executed on QEMU as follows: make run -------------------------------------------------------------------------------- Troubleshooting: Problems caused by out-dated project information can be addressed by issuing one of the following commands then rebuilding the project: make clean # discard results of previous builds # but keep existing configuration info or make pristine # discard results of previous builds # and restore pre-defined configuration info -------------------------------------------------------------------------------- Sample Output: tc_start() - Test Stack Protection Canary Starts main Starts alternate_thread alternate_thread: Input string is too long and stack overflowed! ***** Stack Check Fail! ***** Current thread ID = 0x00103180 Faulting segment:address = 0xdead:0xdeaddead eax: 0xdeaddead, ebx: 0xdeaddead, ecx: 0xdeaddead, edx: 0xdeaddead esi: 0xdeaddead, edi: 0xdeaddead, ebp: 0deaddead, esp: 0xdeaddead eflags: 0xdeaddead Fatal fault in thread 0x00103180!
