Three related defects: - panic() halted with a single hlt instruction (no loop), so any resumable interrupt (LAPIC timer via iretq) caused it to return, allowing callers to continue executing. Add while(1) and declare __attribute__((noreturn)) in both definition and header. - x86_paging_setup_ptp guarded with == WOLFBOOT_PTP_NUM instead of >=, so if the counter ever exceeded that value (after a panic() return) the guard was permanently bypassed. - The ptp pointer was computed before the bounds check, creating an out-of-bounds pointer for one-past-end indices; move the assignment to after the guard so no invalid pointer is ever formed. Add unit-x86-paging-oob test that sets page_table_page_used to WOLFBOOT_PTP_NUM and verifies that every subsequent call to x86_paging_setup_ptp triggers panic (via longjmp stub) rather than silently proceeding with an out-of-bounds memset. |
