how trick linux thinking memory read/write successful? writing c++ library such reads/writes redirected , handled transparently end user. anytime variable written or read from, library need catch request , shoot off hardware simulation handle data there. note library platform dependent on: linux ubuntu 3.16.0-39-generic #53~14.04.1-ubuntu smp x86_64 gnu/linux gcc (ubuntu 4.8.2-19ubuntu1) 4.8.2 current approach: catch sigsegv , increment reg_rip my current approach involves getting memory region using mmap() , shutting off access using mprotect() . have sigsegv handler info containing memory address, export read/write elsewhere, increment context reg_rip. void handle_sigsegv(int code, siginfo_t *info, void *ctx) { void *addr = info->si_addr; ucontext_t *u = (ucontext_t *)ctx; int err = u->uc_mcontext.gregs[reg_err]; bool is_write = (err & 0x2); // send data read/write simulation... // continue execution of program incrementing r...
