    commit 6807c84652b0 ("x86: Enable KASLR by default") enables KASLR
    by default on x86. While KASLR will confuse gdb which resolve kernel
    symbol address from symbol table of vmlinux. We should turn off KASLR for
    kernel debugging.

    …x/kernel/git/shuah/linux-kselftest

    Pull Kselftest updates from Shuah Khan:
    "This update consists of:

    - TAP13 framework and changes to some tests to convert to TAP13.
    Converting kselftest output to standard format will help identify
    run to run differences and pin point failures easily. TAP13 format
    has been in use for several years and the output is human friendly.

    Please find the specification:
    https://testanything.org/tap-version-13-specification.html

    Credit goes to Tim Bird for recommending TAP13 as a suitable
    format, and to Grag KH for kick starting the work with help from
    Paul Elder and Alice Ferrazzi

    The first phase of the TAp13 conversion is included in this update.
    Future updates will include updates to rest of the tests.

    - Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.

    - Kselftest documnetation has been converted to ReST format. Document
    now has a new home under Documentation/dev-tools.

    - kselftest_harness.h is now available for general use as a result of
    Mickaël Salaün's work.

    - Several fixes to skip and/or fail tests gracefully on older
    releases"

  • 94f4a1618   mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objects ... Browse Code »

    Kmemleak requires that vmalloc'ed objects have a minimum reference count
    of 2: one in the corresponding vm_struct object and the other owned by
    the vmalloc() caller. There are cases, however, where the original
    vmalloc() returned pointer is lost and, instead, a pointer to vm_struct
    is stored (see free_thread_stack()). Kmemleak currently reports such
    objects as leaks.

    This patch adds support for treating any surplus references to an object
    as additional references to a specified object. It introduces the
    kmemleak_vmalloc() API function which takes a vm_struct pointer and sets
    its surplus reference passing to the actual vmalloc() returned pointer.
    The __vmalloc_node_range() calling site has been modified accordingly.

    The sparse-based checking for non-RCU accesses to RCU-protected pointers
    has been around for a very long time, and it is now the only type of
    sparse-based checking that is optional. This commit therefore makes
    it unconditional.

  • 9099daed9   mm: kmemleak: avoid using __va() on addresses that don't have a lowmem mapping ... Browse Code »

    Some of the kmemleak_*() callbacks in memblock, bootmem, CMA convert a
    physical address to a virtual one using __va(). However, such physical
    addresses may sometimes be located in highmem and using __va() is
    incorrect, leading to inconsistent object tracking in kmemleak.

    The following functions have been added to the kmemleak API and they take
    a physical address as the object pointer. They only perform the
    corresponding action if the address has a lowmem mapping:

    kmemleak_alloc_phys
    kmemleak_free_part_phys
    kmemleak_not_leak_phys
    kmemleak_ignore_phys

    The affected calling places have been updated to use the new kmemleak
    API.
