    [ Upstream commit ae15a41a641449f536578b0d9ec0e4ade130deb5 ]

    Originally in patch e6d20c55a4 ("openrisc: entry: Fix delay slot
    detection") I fixed delay slot detection, but only for QEMU. We missed
    that hardware delay slot detection using delay slot exception flag (DSX)
    was still broken. This was because QEMU set the DSX flag in both
    pre-exception supervision register (ESR) and supervision register (SR)
    register, but on real hardware the DSX flag is only set on the SR
    register during exceptions.

    Fix this by carrying the DSX flag into the SR register during exception.
    We also update the DSX flag read locations to read the value from the SR
    register not the pt_regs SR register which represents ESR. The ESR
    should never have the DSX flag set.

    In the process I updated/removed a few comments to match the current
    state. Including removing a comment saying that the DSX detection logic
    was inefficient and needed to be rewritten.

    I have tested this on QEMU with a patch ensuring it matches the hardware
    specification.

  • 2abfcdf8e   kmemcheck: remove annotations ... Browse Code »

    commit 4950276672fce5c241857540f8561c440663673d upstream.

    Patch series "kmemcheck: kill kmemcheck", v2.

    As discussed at LSF/MM, kill kmemcheck.

    KASan is a replacement that is able to work without the limitation of
    kmemcheck (single CPU, slow). KASan is already upstream.

    We are also not aware of any users of kmemcheck (or users who don't
    consider KASan as a suitable replacement).

    The only objection was that since KASAN wasn't supported by all GCC
    versions provided by distros at that time we should hold off for 2
    years, and try again.

    Now that 2 years have passed, and all distros provide gcc that supports
    KASAN, kill kmemcheck again for the very same reasons.

    This patch (of 4):

    Remove kmemcheck annotations, and calls to kmemcheck from the kernel.

  • 34ad59099   signal/openrisc: Fix do_unaligned_access to send the proper signal ... Browse Code »

    commit 500d58300571b6602341b041f97c082a461ef994 upstream.

    While reviewing the signal sending on openrisc the do_unaligned_access
    function stood out because it is obviously wrong. A comment about an
    si_code set above when actually si_code is never set. Leading to a
    random si_code being sent to userspace in the event of an unaligned
    access.

    Looking further SIGBUS BUS_ADRALN is the proper pair of signal and
    si_code to send for an unaligned access. That is what other
    architectures do and what is required by posix.

    Given that do_unaligned_access is broken in a way that no one can be
    relying on it on openrisc fix the code to just do the right thing.

  • e2be04c7f   License cleanup: add SPDX license identifier to uapi header files with a license ... Browse Code »

    Many user space API headers have licensing information, which is either
    incomplete, badly formatted or just a shorthand for referring to the
    license under which the file is supposed to be. This makes it hard for
    compliance tools to determine the correct license.

    Update these files with an SPDX license identifier. The identifier was
    chosen based on the license information in the file.

    GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
    identifier with the added 'WITH Linux-syscall-note' exception, which is
    the officially assigned exception identifier for the kernel syscall
    exception:

    NOTE! This copyright does *not* cover user programs that use kernel
    services by normal system calls - this is merely considered normal use
    of the kernel, and does *not* fall under the heading of "derived work".

    This exception makes it possible to include GPL headers into non GPL
    code, without confusing license compliance tools.

    Headers which have either explicit dual licensing or are just licensed
    under a non GPL license are updated with the corresponding SPDX
    identifier and the GPLv2 with syscall exception identifier. The format
    is:
    ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)

    SPDX license identifiers are a legally binding shorthand, which can be
    used instead of the full boiler plate text. The update does not remove
    existing license information as this has to be done on a case by case
    basis and the copyright holders might have to be consulted. This will
    happen in a separate step.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne. See the previous patch in this series for the
    methodology of how this patch was researched.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 4c97a0c8f   arch: define CPU_BIG_ENDIAN for all fixed big endian archs ... Browse Code »

    Patch series "Define CPU_BIG_ENDIAN or warn for inconsistencies", v3.

    While working on enabling queued rwlock on SPARC, found this following
    code in include/asm-generic/qrwlock.h which uses CONFIG_CPU_BIG_ENDIAN to
    clear a byte.

    static inline u8 *__qrwlock_write_byte(struct qrwlock *lock)
    {
    return (u8 *)lock + 3 * IS_BUILTIN(CONFIG_CPU_BIG_ENDIAN);
    }

    Problem is many of the fixed big endian architectures don't define
    CPU_BIG_ENDIAN and clears the wrong byte.

    Define CPU_BIG_ENDIAN for all the fixed big endian architecture to fix it.

    Also found few more references of this config parameter in
    drivers/of/base.c
    drivers/of/fdt.c
    drivers/tty/serial/earlycon.c
    drivers/tty/serial/serial_core.c

    problems in the above code already. Remove the work-around.

  • 30d6e0a41   futex: Remove duplicated code and fix undefined behaviour ... Browse Code »

    There is code duplicated over all architecture's headers for
    futex_atomic_op_inuser. Namely op decoding, access_ok check for uaddr,
    and comparison of the result.

    Remove this duplication and leave up to the arches only the needed
    assembly which is now in arch_futex_atomic_op_inuser.

    This effectively distributes the Will Deacon's arm64 fix for undefined
    behaviour reported by UBSAN to all architectures. The fix was done in
    commit 5f16a046f8e1 (arm64: futex: Fix undefined behaviour with
    FUTEX_OP_OPARG_SHIFT usage). Look there for an example dump.

    And as suggested by Thomas, check for negative oparg too, because it was
    also reported to cause undefined behaviour report.

    Note that s390 removed access_ok check in d12a29703 ("s390/uaccess:
    remove pointless access_ok() checks") as access_ok there returns true.
    We introduce it back to the helper for the sake of simplicity (it gets
    optimized away anyway).

    Since commit fcc8487d477a ("uapi: export all headers under uapi
    directories"), all (and only) headers under uapi directories are
    exported, but asm-generic wrappers are still exceptions.

    To complete de-coupling the uapi from kernel headers, move generic-y
    of exported headers to uapi/asm/Kbuild.

    With this change, "make headers_install" will just need to parse
    uapi/asm/Kbuild to build up exported headers.

    Also, move "generic-y += kprobes.h" up in order to keep the entries
    sorted.

  • b0f5a8f32   kthread: fix boot hang (regression) on MIPS/OpenRISC ... Browse Code »

    This fixes a regression in commit 4d6501dce079 where I didn't notice
    that MIPS and OpenRISC were reinitialising p->{set,clear}_child_tid to
    NULL after our initialisation in copy_process().

    We can simply get rid of the arch-specific initialisation here since it
    is now always done in copy_process() before hitting copy_thread{,_tls}().

    Review notes:

    - As far as I can tell, copy_process() is the only user of
    copy_thread_tls(), which is the only caller of copy_thread() for
    architectures that don't implement copy_thread_tls().

    - After this patch, there is no arch-specific code touching
    p->set_child_tid or p->clear_child_tid whatsoever.

    - It may look like MIPS/OpenRISC wanted to always have these fields be
    NULL, but that's not true, as copy_process() would unconditionally
    set them again _after_ calling copy_thread_tls() before commit
    4d6501dce079.

    In fact, all headers under uapi directories should be exported, thus it's
    useless to have an exhaustive list.

    After this patch, the following files, which were not exported, are now
    exported (with make headers_install_all):
    asm-arc/kvm_para.h
    asm-arc/ucontext.h

    Note that I have removed from this list the files which are generated in every
    exported directories (like .install or .install.cmd).

    Thanks to Julien Floret for the tip to get all
    subdirs with a pure makefile command.

    For the record, note that exported files for asm directories are a mix of
    files listed by:
    - include/uapi/asm-generic/Kbuild.asm;
    - arch//include/uapi/asm/Kbuild;
    - arch//include/asm/Kbuild.

    Was getting the following error with allmodconfig:

    ERROR: "__get_user_bad" [lib/test_user_copy.ko] undefined!

    This was simply a missing break statement, causing an unwanted fall
    through.

    When building allmodconfig this warning shows.

    fs/ocfs2/file.c: In function 'ocfs2_file_write_iter':
    ./arch/openrisc/include/asm/cmpxchg.h:81:3: warning: value computed is
    not used [-Wunused-value]
    ((typeof(*(ptr)))__xchg((unsigned long)(with), (ptr), sizeof(*(ptr))))
    ^

    Applying the same patch logic that was done to the cmpxchg macro.

  • 9849a5697   arch, mm: convert all architectures to use 5level-fixup.h ... Browse Code »

    If an architecture uses 4level-fixup.h we don't need to do anything as
    it includes 5level-fixup.h.

    If an architecture uses pgtable-nop*d.h, define __ARCH_USE_5LEVEL_HACK
    before inclusion of the header. It makes asm-generic code to use
    5level-fixup.h.

    If an architecture has 4-level paging or folds levels on its own,
    include 5level-fixup.h directly.
