      "message": "Allocate a small guard region around the shadow call stack.\n\nThis lets us do two things:\n\n1) Make setjmp and longjmp compatible with shadow call stack.\n   To avoid leaking the shadow call stack address into memory, only the\n   lower log2(SCS_SIZE) bits of x18 are stored to jmp_buf. This requires\n   allocating an additional guard page so that we\u0027re guaranteed to be\n   able to allocate a sufficiently aligned SCS.\n\n2) SCS overflow detection. Overflows now result in a SIGSEGV instead\n   of corrupting the allocation that comes after it.\n\nChange-Id: I04d6634f96162bf625684672a87fba8b402b7fd1\nTest: bionic-unit-tests\n"
