      "message": "[S390] noexec protection\n\nThis provides a noexec protection on s390 hardware. Our hardware does\nnot have any bits left in the pte for a hw noexec bit, so this is a\ndifferent approach using shadow page tables and a special addressing\nmode that allows separate address spaces for code and data.\n\nAs a special feature of our \"secondary-space\" addressing mode, separate\npage tables can be specified for the translation of data addresses\n(storage operands) and instruction addresses. The shadow page table is\nused for the instruction addresses and the standard page table for the\ndata addresses.\nThe shadow page table is linked to the standard page table by a pointer\nin page-\u003elru.next of the struct page corresponding to the page that\ncontains the standard page table (since page-\u003eprivate is not really\nprivate with the pte_lock and the page table pages are not in the LRU\nlist).\nDepending on the software bits of a pte, it is either inserted into\nboth page tables or just into the standard (data) page table. Pages of\na vma that does not have the VM_EXEC bit set get mapped only in the\ndata address space. Any try to execute code on such a page will cause a\npage translation exception. The standard reaction to this is a SIGSEGV\nwith two exceptions: the two system call opcodes 0x0a77 (sys_sigreturn)\nand 0x0aad (sys_rt_sigreturn) are allowed. They are stored by the\nkernel to the signal stack frame. Unfortunately, the signal return\nmechanism cannot be modified to use an SA_RESTORER because the\nexception unwinding code depends on the system call opcode stored\nbehind the signal stack frame.\n\nThis feature requires that user space is executed in secondary-space\nmode and the kernel in home-space mode, which means that the addressing\nmodes need to be switched and that the noexec protection only works\nfor user space.\nAfter switching the addressing modes, we cannot use the mvcp/mvcs\ninstructions anymore to copy between kernel and user space. A new\nmvcos instruction has been added to the z9 EC/BC hardware which allows\nto copy between arbitrary address spaces, but on older hardware the\npage tables need to be walked manually.\n\nSigned-off-by: Gerald Schaefer \u003cgeraldsc@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n"
