I am trying to allocate the 0-th page with mmap function in my code.
I am always getting this error with this error-code: mmap error ffffffff
Then I was searching the internet for this topic and I have found the
same topic at stackoverflow web pages.
char *zero = mmap(NULL, 4096, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS | MAP_FIXED, -1, 0);
*(char *)(NULL) = 'A';
printf("%c\n", *zero);
still yields 'A' here with 6.10.2 w/ vm.mmap_min_addr=0.
Yeah and mind LSMs...
