  • 09cbfeaf1   mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros ... Browse Code »

    PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
    ago with promise that one day it will be possible to implement page
    cache with bigger chunks than PAGE_SIZE.

    This promise never materialized. And unlikely will.

    We have many places where PAGE_CACHE_SIZE assumed to be equal to
    PAGE_SIZE. And it's constant source of confusion on whether
    PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
    especially on the border between fs and mm.

    Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
    breakage to be doable.

    Let's stop pretending that pages in page cache are special. They are
    not.

    The changes are pretty straight-forward:

    - << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

    - page_cache_get() -> get_page();

    - page_cache_release() -> put_page();

    This patch contains automated changes generated with coccinelle using
    script below. For some reason, coccinelle doesn't patch header files.
    I've called spatch for them manually.

    The only adjustment after coccinelle is revert of changes to
    PAGE_CAHCE_ALIGN definition: we are going to drop it later.

    There are few places in the code where coccinelle didn't reach. I'll
    fix them manually in a separate patch. Comments and documentation also
    will be addressed with the separate patch.

    pstore doesn't support unregistering yet. It was marked as TODO.
    This patch adds some code to fix it:
    1) Add functions to unregister kmsg/console/ftrace/pmsg.
    2) Add a function to free compression buffer.
    3) Unmap the memory and free it.
    4) Add a function to unregister pstore filesystem.

    Pull user namespace updates from Eric Biederman:
    "Long ago and far away when user namespaces where young it was realized
    that allowing fresh mounts of proc and sysfs with only user namespace
    permissions could violate the basic rule that only root gets to decide
    if proc or sysfs should be mounted at all.

    Some hacks were put in place to reduce the worst of the damage could
    be done, and the common sense rule was adopted that fresh mounts of
    proc and sysfs should allow no more than bind mounts of proc and
    sysfs. Unfortunately that rule has not been fully enforced.

    There are two kinds of gaps in that enforcement. Only filesystems
    mounted on empty directories of proc and sysfs should be ignored but
    the test for empty directories was insufficient. So in my tree
    directories on proc, sysctl and sysfs that will always be empty are
    created specially. Every other technique is imperfect as an ordinary
    directory can have entries added even after a readdir returns and
    shows that the directory is empty. Special creation of directories
    for mount points makes the code in the kernel a smidge clearer about
    it's purpose. I asked container developers from the various container
    projects to help test this and no holes were found in the set of mount
    points on proc and sysfs that are created specially.

    This set of changes also starts enforcing the mount flags of fresh
    mounts of proc and sysfs are consistent with the existing mount of
    proc and sysfs. I expected this to be the boring part of the work but
    unfortunately unprivileged userspace winds up mounting fresh copies of
    proc and sysfs with noexec and nosuid clear when root set those flags
    on the previous mount of proc and sysfs. So for now only the atime,
    read-only and nodev attributes which userspace happens to keep
    consistent are enforced. Dealing with the noexec and nosuid
    attributes remains for another time.

    This set of changes also addresses an issue with how open file
    descriptors from /proc//ns/* are displayed. Recently readlink of
    /proc//fd has been triggering a WARN_ON that has not been
    meaningful since it was added (as all of the code in the kernel was
    converted) and is not now actively wrong.

    There is also a short list of issues that have not been fixed yet that
    I will mention briefly.

    It is possible to rename a directory from below to above a bind mount.
    At which point any directory pointers below the renamed directory can
    be walked up to the root directory of the filesystem. With user
    namespaces enabled a bind mount of the bind mount can be created
    allowing the user to pick a directory whose children they can rename
    to outside of the bind mount. This is challenging to fix and doubly
    so because all obvious solutions must touch code that is in the
    performance part of pathname resolution.

    As mentioned above there is also a question of how to ensure that
    developers by accident or with purpose do not introduce exectuable
    files on sysfs and proc and in doing so introduce security regressions
    in the current userspace that will not be immediately obvious and as
    such are likely to require breaking userspace in painful ways once
    they are recognized"

  • 027bc8b08   pstore-ram: Allow optional mapping with pgprot_noncached ... Browse Code »

    On some ARMs the memory can be mapped pgprot_noncached() and still
    be working for atomic operations. As pointed out by Colin Cross
    , in some cases you do want to use
    pgprot_noncached() if the SoC supports it to see a debug printk
    just before a write hanging the system.

    On ARMs, the atomic operations on strongly ordered memory are
    implementation defined. So let's provide an optional kernel parameter
    for configuring pgprot_noncached(), and use pgprot_writecombine() by
    default.

  • 7ae9cb819   pstore-ram: Fix hangs by using write-combine mappings ... Browse Code »

    Currently trying to use pstore on at least ARMs can hang as we're
    mapping the peristent RAM with pgprot_noncached().

    On ARMs, pgprot_noncached() will actually make the memory strongly
    ordered, and as the atomic operations pstore uses are implementation
    defined for strongly ordered memory, they may not work. So basically
    atomic operations have undefined behavior on ARM for device or strongly
    ordered memory types.

    Let's fix the issue by using write-combine variants for mappings. This
    corresponds to normal, non-cacheable memory on ARM. For many other
    architectures, this change does not change the mapping type as by
    default we have:

    #define pgprot_writecombine pgprot_noncached

    The reason why pgprot_noncached() was originaly used for pstore
    is because Colin Cross had observed lost
    debug prints right before a device hanging write operation on some
    systems. For the platforms supporting pgprot_noncached(), we can
    add a an optional configuration option to support that. But let's
    get pstore working first before adding new features.

  • a28726b4f   pstore/ram: Strip ramoops header for correct decompression ... Browse Code »

    pstore compression/decompression was added during 3.12.
    The ramoops driver prepends a "====timestamp.timestamp-C|D\n"
    header to the compressed record before handing it over to pstore
    driver which doesn't know about the header. In pstore_decompress(),
    the pstore driver reads the first "==" as a zlib header, so the
    decompression always fails. For example, this causes the driver
    to write /dev/pstore/dmesg-ramoops-0.enc.z instead of
    /dev/pstore/dmesg-ramoops-0.

    This patch makes the ramoops driver remove the header before
    pstore decompression.

  • ef7488535   fs/pstore: logging clean-up ... Browse Code »

    - Define pr_fmt in plateform.c and ram_core.c for global prefix.

    - Coalesce format fragments.

    - Separate format/arguments on lines > 80 characters.

    Note: Some pr_foo() were initially declared without prefix and therefore
    this could break existing log analyzer.

    [akpm@linux-foundation.org: missed a couple of prefix removals]

    Pull ext4 updates from Ted Ts'o:
    "Major changes for 3.14 include support for the newly added ZERO_RANGE
    and COLLAPSE_RANGE fallocate operations, and scalability improvements
    in the jbd2 layer and in xattr handling when the extended attributes
    spill over into an external block.

    Other than that, the usual clean ups and minor bug fixes"
