  • b11b53342   [S390] Improve address space mode selection. ... Browse Code »

    Introduce user_mode to replace the two variables switch_amode and
    s390_noexec. There are three valid combinations of the old values:
    1) switch_amode == 0 && s390_noexec == 0
    2) switch_amode == 1 && s390_noexec == 0
    3) switch_amode == 1 && s390_noexec == 1
    They get replaced by
    1) user_mode == HOME_SPACE_MODE
    2) user_mode == PRIMARY_SPACE_MODE
    3) user_mode == SECONDARY_SPACE_MODE
    The new kernel parameter user_mode=[primary,secondary,home] lets
    you choose the address space mode the user space processes should
    use. In addition the CONFIG_S390_SWITCH_AMODE config option
    is removed.

    The syscall enter/exit tracing is no longer specific to just ftrace, so
    they now have names that reflect their tie to tracepoints instead.

  • 411ed3225   [S390] zfcpdump support. ... Browse Code »

    s390 machines provide hardware support for creating Linux dumps on SCSI
    disks. For creating a dump a special purpose dump Linux is used. The first
    32 MB of memory are saved by the hardware before the dump Linux is
    booted. Via an SCLP interface, the saved memory can be accessed from
    Linux. This patch exports memory and registers of the crashed Linux to
    userspace via a debugfs file. For more information refer to
    Documentation/s390/zfcpdump.txt, which is included in this patch.

    Generic bug implementation for s390. Will increase the value of the
    console output on BUG() statements since registers r0-r5,r14 will
    not be clobbered by a printk() call that was previously done before
    the illegal instruction of BUG() was hit.
    Also implements an architecture specific WARN_ON(). Output of that
    could be increased but requires common code change.

  • ab14de6c3   [S390] Convert memory detection into C code. ... Browse Code »

    Hopefully this will make it more maintainable and less error prone.
    Code makes use of search_exception_tables(). Since it calls this
    function before the kernel exeception table is sorted, there is an
    early call to sort_main_extable().

    This way it's easy to use the already present infrastructure of fixup
    sections. Also this would allows to easily convert the rest of
    head[31|64].S into C code.

  • 1b2782948   [S390] Support for s390 Pseudo Random Number Generator ... Browse Code »

    Starting with the z9 the CPU Cryptographic Assist Facility comes with
    an integrated Pseudo Random Number Generator. The generator creates
    random numbers by an algorithm similar to the ANSI X9.17 standard.
    The pseudo-random numbers can be accessed via a character device driver
    node called /dev/prandom. Similar to /dev/urandom any amount of bytes
    can be read from the device without blocking.

  • c1821c2e9   [S390] noexec protection ... Browse Code »

    This provides a noexec protection on s390 hardware. Our hardware does
    not have any bits left in the pte for a hw noexec bit, so this is a
    different approach using shadow page tables and a special addressing
    mode that allows separate address spaces for code and data.

    As a special feature of our "secondary-space" addressing mode, separate
    page tables can be specified for the translation of data addresses
    (storage operands) and instruction addresses. The shadow page table is
    used for the instruction addresses and the standard page table for the
    data addresses.
    The shadow page table is linked to the standard page table by a pointer
    in page->lru.next of the struct page corresponding to the page that
    contains the standard page table (since page->private is not really
    private with the pte_lock and the page table pages are not in the LRU
    list).
    Depending on the software bits of a pte, it is either inserted into
    both page tables or just into the standard (data) page table. Pages of
    a vma that does not have the VM_EXEC bit set get mapped only in the
    data address space. Any try to execute code on such a page will cause a
    page translation exception. The standard reaction to this is a SIGSEGV
    with two exceptions: the two system call opcodes 0x0a77 (sys_sigreturn)
    and 0x0aad (sys_rt_sigreturn) are allowed. They are stored by the
    kernel to the signal stack frame. Unfortunately, the signal return
    mechanism cannot be modified to use an SA_RESTORER because the
    exception unwinding code depends on the system call opcode stored
    behind the signal stack frame.

    This feature requires that user space is executed in secondary-space
    mode and the kernel in home-space mode, which means that the addressing
    modes need to be switched and that the noexec protection only works
    for user space.
    After switching the addressing modes, we cannot use the mvcp/mvcs
    instructions anymore to copy between kernel and user space. A new
    mvcos instruction has been added to the z9 EC/BC hardware which allows
    to copy between arbitrary address spaces, but on older hardware the
    page tables need to be walked manually.

    This patch moves the config options for the s390 crypto instructions
    to the standard "Hardware crypto devices" menu. In addition some
    cleanup has been done: use a flag for supported keylengths, add a
    warning about machien limitation, return ENOTSUPP in case the
    hardware has no support, remove superfluous printks and update
    email addresses.

  • bcc8bcb1f   [S390] revert add_active_range() usage patch. ... Browse Code »

    Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
    s390. DCSS needs initialized struct pages to work. With the usage of
    add_active_range() only the struct pages for physically present pages
    are initialized.
    This could be fixed if the DCSS driver would initiliaze the struct pages
    itself, but this doesn't work too. This is because the mem_map array
    does not include holes after the last present memory area and therefore
    there is nothing that could be initialized.
    To fix this and to avoid some dirty hacks revert this patch for now.
    Will be added later when we move to a virtual mem_map.
