    two predefined FPGA bitstreams before booting the kernel. Both define an

  • Pull xfs fixes from Dave Chinner:
    "This update fixes a warning in the new pagecache_isize_extended() and
    updates some related comments, another fix for zero-range
    misbehaviour, and an unforntuately large set of fixes for regressions
    in the bulkstat code.

    The bulkstat fixes are large but necessary. I wouldn't normally push
    such a rework for a -rcX update, but right now xfsdump can silently
    create incomplete dumps on 3.17 and it's possible that even xfsrestore
    won't notice that the dumps were incomplete. Hence we need to get
    this update into 3.17-stable kernels ASAP.

    In more detail, the refactoring work I committed in 3.17 has exposed a
    major hole in our QA coverage. With both xfsdump (the major user of
    bulkstat) and xfsrestore silently ignoring missing files in the
    dump/restore process, incomplete dumps were going unnoticed if they
    were being triggered. Many of the dump/restore filesets were so small
    that they didn't evenhave a chance of triggering the loop iteration
    bugs we introduced in 3.17, so we didn't exercise the code
    sufficiently, either.

    We have already taken steps to improve QA coverage in xfstests to
    avoid this happening again, and I've done a lot of manual verification
    of dump/restore on very large data sets (tens of millions of inodes)
    of the past week to verify this patch set results in bulkstat behaving
    the same way as it does on 3.16.

    Unfortunately, the fixes are not exactly simple - in tracking down the
    problem historic API warts were discovered (e.g xfsdump has been
    working around a 20 year old bug in the bulkstat API for the past 10
    years) and so that complicated the process of diagnosing and fixing
    the problems. i.e. we had to fix bugs in the code as well as
    discover and re-introduce the userspace visible API bugs that we
    unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.

    Summary:

    - incorrect warnings about i_mutex locking in pagecache_isize_extended()
    and updates comments to match expected locking
    - another zero-range bug fix for stray file size updates
    - a bunch of fixes for regression in the bulkstat code introduced in
    3.17"

  • There is a race condition when removing glue directory.
    It can be reproduced in following test:

    path 1: Add first child device
    device_add()
    get_device_parent()
    /*find parent from glue_dirs.list*/
    list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry)
    if (k->parent == parent_kobj) {
    kobj = kobject_get(k);
    break;
    }
    ....

    path2: Remove last child device under glue dir
    device_del()
    cleanup_device_parent()
    cleanup_glue_dir()
    kobject_put(glue_dir);

    If path2 has been called cleanup_glue_dir(), but not
    call kobject_put(glue_dir), the glue dir is still
    in parent's kset list. Meanwhile, path1 find the glue
    dir from the glue_dirs.list. Path2 may release glue dir
    before path1 call kobject_get(). So kernel will report
    the warning and bug_on.

    This is a "classic" problem we have of a kref in a list
    that can be found while the last instance could be removed
    at the same time.

    This patch reuse gdp_mutex to fix this race condition.

    the latest kernel still has this bug.

  • Starting with version 2.24.51.20140728 MIPS binutils complain loudly
    about mixing soft-float and hard-float object files, leading to this
    build failure since GCC is invoked with "-msoft-float" on MIPS:

    {standard input}: Warning: .gnu_attribute 4,3 requires `softfloat'
    LD arch/mips/alchemy/common/built-in.o
    mipsel-softfloat-linux-gnu-ld: Warning: arch/mips/alchemy/common/built-in.o
    uses -msoft-float (set by arch/mips/alchemy/common/prom.o),
    arch/mips/alchemy/common/sleeper.o uses -mhard-float

    To fix this, we detect if GAS is new enough to support "-msoft-float" command
    option, and if it does, we can let GCC pass it to GAS; but then we also need
    to sprinkle the files which make use of floating point registers with the
    necessary ".set hardfloat" directives.

  • The bulkstat main loop progress is tracked by the "lastino"
    variable, which is a full 64 bit inode. However, the loop actually
    works on agno/agino pairs, and so there's a significant disconnect
    between the rest of the loop and the main cursor. Convert this to
    use the agino, and pass the agino into the chunk formatting function
    and convert it too.

    This gets rid of the inconsistency in the loop processing, and
    finally makes it simple for us to skip inodes at any point in the
    loop simply by incrementing the agino cursor.

  • The error propagation is a horror - xfs_bulkstat() returns
    a rval variable which is only set if there are formatter errors. Any
    sort of btree walk error or corruption will cause the bulkstat walk
    to terminate but will not pass an error back to userspace. Worse
    is the fact that formatter errors will also be ignored if any inodes
    were correctly formatted into the user buffer.

    Hence bulkstat can fail badly yet still report success to userspace.
    This causes significant issues with xfsdump not dumping everything
    in the filesystem yet reporting success. It's not until a restore
    fails that there is any indication that the dump was bad and tha
    bulkstat failed. This patch now triggers xfsdump to fail with
    bulkstat errors rather than silently missing files in the dump.

    This now causes bulkstat to fail when the lastino cookie does not
    fall inside an existing inode chunk. The pre-3.17 code tolerated
    that error by allowing the code to move to the next inode chunk
    as the agino target is guaranteed to fall into the next btree
    record.

    With the fixes up to this point in the series, xfsdump now passes on
    the troublesome filesystem image that exposes all these bugs.

  • The loop construct has issues:
    - clustidx is completely unused, so remove it.
    - the loop tries to be smart by terminating when the
    "freecount" tells it that all inodes are free. Just drop
    it as in most cases we have to scan all inodes in the
    chunk anyway.
    - move the "user buffer left" condition check to the only
    point where we consume space int eh user buffer.
    - move the initialisation of agino out of the loop, leaving
    just a simple loop control logic using the clusteridx.

    Also, double handling of the user buffer variables leads to problems
    tracking the current state - use the cursor variables directly
    rather than keeping local copies and then having to update the
    cursor before returning.

  • The xfs_bulkstat_agichunk formatting cursor takes buffer values from
    the main loop and passes them via the structure to the chunk
    formatter, and the writes the changed values back into the main loop
    local variables. Unfortunately, this complex dance is full of corner
    cases that aren't handled correctly.

    The biggest problem is that it is double handling the information in
    both the main loop and the chunk formatting function, leading to
    inconsistent updates and endless loops where progress is not made.

    To fix this, push the struct xfs_bulkstat_agichunk outwards to be
    the primary holder of user buffer information. this removes the
    double handling in the main loop.

    Also, pass the last inode processed by the chunk formatter as a
    separate parameter as it purely an output variable and is not
    related to the user buffer consumption cursor.

    Finally, the chunk formatting code is not shared by anyone, so make
    it local to xfs_itable.c.

  • The bulkstat code has several different ways of detecting the end of
    an AG when doing a walk. They are not consistently detected, and the
    code that checks for the end of AG conditions is not consistently
    coded. Hence the are conditions where the walk code can get stuck in
    an endless loop making no progress and not triggering any
    termination conditions.

    Convert all the "tmp/i" status return codes from btree operations
    to a common name (stat) and apply end-of-ag detection to these
    operations consistently.

  • XFS doesn't always hold i_mutex when calling truncate_setsize() and it
    uses a different lock to serialize truncates and writes. So fix the
    comment before truncate_setsize().

  • Add new quirk for devices that cannot handle control-line state
    requests.

    Note that we currently send these requests to all devices, regardless of
    whether they claim to support it, but that errors are only logged if
    support is claimed.

    Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which
    only changed the timings for these requests slightly, this has been
    reported to cause occasional firmware crashes on Simtec Electronics
    Entropy Key devices after re-enumeration. Enable the quirk for this
    device.

    usb: fixes for v3.18-rc4

    A single fix this for dwc2 this time. Because of
    excessive debugging messages, dwc2 would sometimes
    fail enumeration. The fix is simple, just converting
    a dev_info() into dev_dbg().

    introduces a race window where a pty master can be signalled that the pty
    slave was closed before all the data that the slave wrote is delivered.
    Commit f8747d4a466a ("tty: Fix pty master read() after slave closes") fixed the
    problem in case of n_tty_read, but the problem still exists for n_tty_poll.
