  • b70174509   docs: can.rst: fix a footnote reference ... Browse Code »

    As stated at:
    http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#footnotes

    A footnote should contain either a number, a reference or
    an auto number, e. g.:
    [1], [#f1] or [#].

    While using [*] accidentaly works for html, it fails for other
    document outputs. In particular, it causes an error with LaTeX
    output, causing all books after networking to not be built.

    So, replace it by a valid syntax.

  • ee410f15b   lib/test_printf.c: call wait_for_random_bytes() before plain %p tests ... Browse Code »

    If the test_printf module is loaded before the crng is initialized, the
    plain 'p' tests will fail because the printed address will not be hashed
    and the buffer will contain '(ptrval)' instead.

    This patch adds a call to wait_for_random_bytes() before plain 'p' tests
    to make sure the crng is initialized.

  • fe6bdfc8e   mm: fix oom_kill event handling ... Browse Code »

    Commit e27be240df53 ("mm: memcg: make sure memory.events is uptodate
    when waking pollers") converted most of memcg event counters to
    per-memcg atomics, which made them less confusing for a user. The
    "oom_kill" counter remained untouched, so now it behaves differently
    than other counters (including "oom"). This adds nothing but confusion.

    Let's fix this by adding the MEMCG_OOM_KILL event, and follow the
    MEMCG_OOM approach.

    This also removes a hack from count_memcg_event_mm(), introduced earlier
    specially for the OOM_KILL counter.

  • 0825a6f98   mm: use octal not symbolic permissions ... Browse Code »

    mm/*.c files use symbolic and octal styles for permissions.

    Using octal and not symbolic permissions is preferred by many as more
    readable.

    https://lkml.org/lkml/2016/8/2/1945

    Prefer the direct use of octal for permissions.

    Done using
    $ scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace mm/*.c
    and some typing.

    Before: $ git grep -P -w "0[0-7]{3,3}" mm | wc -l
    44
    After: $ git grep -P -w "0[0-7]{3,3}" mm | wc -l
    86

    Miscellanea:

    o Whitespace neatening around these conversions.

    Use new return type vm_fault_t for fault handler. For now, this is just
    documenting that the function returns a VM_FAULT value rather than an
    errno. Once all instances are converted, vm_fault_t will become a
    distinct type.

  • ec67aaa46   sysvipc/sem: mitigate semnum index against spectre v1 ... Browse Code »

    Both smatch and coverity are reporting potential issues with spectre
    variant 1 with the 'semnum' index within the sma->sems array, ie:

    ipc/sem.c:388 sem_lock() warn: potential spectre issue 'sma->sems'
    ipc/sem.c:641 perform_atomic_semop_slow() warn: potential spectre issue 'sma->sems'
    ipc/sem.c:721 perform_atomic_semop() warn: potential spectre issue 'sma->sems'

    Avoid any possible speculation by using array_index_nospec() thus
    ensuring the semnum value is bounded to [0, sma->sem_nsems). With the
    exception of sem_lock() all of these are slowpaths.

  • 758517202   arm: port KCOV to arm ... Browse Code »

    KCOV is code coverage collection facility used, in particular, by
    syzkaller system call fuzzer. There is some interest in using syzkaller
    on arm devices. So port KCOV to arm.

    On implementation level this merely declares that KCOV is supported and
    disables instrumentation of 3 special cases. Reasons for disabling are
    commented in code.

    Tested with qemu-system-arm/vexpress-a15.

  • 0ed557aa8   sched/core / kcov: avoid kcov_area during task switch ... Browse Code »

    During a context switch, we first switch_mm() to the next task's mm,
    then switch_to() that new task. This means that vmalloc'd regions which
    had previously been faulted in can transiently disappear in the context
    of the prev task.

    Functions instrumented by KCOV may try to access a vmalloc'd kcov_area
    during this window, and as the fault handling code is instrumented, this
    results in a recursive fault.

    We must avoid accessing any kcov_area during this window. We can do so
    with a new flag in kcov_mode, set prior to switching the mm, and cleared
    once the new task is live. Since task_struct::kcov_mode isn't always a
    specific enum kcov_mode value, this is made an unsigned int.

    The manipulation is hidden behind kcov_{prepare,finish}_switch() helpers,
    which are empty for !CONFIG_KCOV kernels.

    The code uses macros because I can't use static inline functions without a
    circular include dependency between and ,
    since the definition of task_struct uses things defined in
