    Pull ext4 bugfixes from Ted Ts'o:
    "These changes contains a fix for overlayfs interacting with some
    (badly behaved) dentry code in various file systems. These have been
    reviewed by Al and the respective file system mtinainers and are going
    through the ext4 tree for convenience.

    This also has a few ext4 encryption bug fixes that were discovered in
    Android testing (yes, we will need to get these sync'ed up with the
    fs/crypto code; I'll take care of that). It also has some bug fixes
    and a change to ignore the legacy quota options to allow for xfstests
    regression testing of ext4's internal quota feature and to be more
    consistent with how xfs handles this case"

  • 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.

  • be62a1a8f   nfs: use file_dentry() ... Browse Code »

    NFS may be used as lower layer of overlayfs and accessing f_path.dentry can
    lead to a crash.

    Fix by replacing direct access of file->f_path.dentry with the
    file_dentry() accessor, which will always return a native object.

  • d9186c039   nfs/blocklayout: add SCSI layout support ... Browse Code »

    This is a trivial extension to the block layout driver to support the
    new SCSI layouts draft. There are three changes:

    - device identifcation through the SCSI VPD page. This allows us to
    directly use the udev generated persistent device names instead of
    requiring an expensive lookup by crawling every block device node
    in /dev and reading a signature for it.
    - use of SCSI persistent reservations to protect device access and
    allow for robust fencing. On the client sides this just means
    registering and unregistering a server supplied key.
    - an optimized LAYOUTCOMMIT payload that doesn't send unessecary
    fields to the server.

    If the server reboots while there is a layoutget outstanding, then
    the call to pnfs_choose_layoutget_stateid() will fail with an EAGAIN
    error, which causes an infinite loop in send_layoutget(). The reason
    why we never break out of the loop is that the layout 'plh_block_lgets'
    field is never cleared.

    Fix is to replace plh_block_lgets with NFS_LAYOUT_INVALID_STID, which
    can be reset after a new layoutget.

  • 4bdf87ebd   nfs4: fix stateid handling for the NFS v4.2 operations ... Browse Code »

    The newly added NFS v4.2 operations (ALLOCATE, DEALLOCATE, SEEK and CLONE)
    use a helper called nfs42_set_rw_stateid to select a stateid that is sent
    to the server. But they don't set the inode and state fields in the
    nfs4_exception structure, and this don't partake in the stateid recovery
    protocol. Because of this they will simply return errors insted of trying
    to recover a stateid when the server return a BAD_STATEID error.

    Additionally CLONE has the problem that it operates on two files and thus
    two stateids, and thus needs to call the exception handler twice to
    recover stateids.

    While we're at it stop grabbing an addititional reference to the open
    context in all these operations - having the file open guarantees that
    the open context won't go away.

    All this can be produces with the generic/168 and generic/170 tests in
    xfstests which stress the CLONE stateid handling.

    In the case where d_add_unique() finds an appropriate alias to use it will
    have already incremented the reference count. An additional dget() to swap
    the open context's dentry is unnecessary and will leak a reference.

  • 13c13a6ad   pNFS: Fix missing layoutreturn calls ... Browse Code »

    The layoutreturn code currently relies on pnfs_put_lseg() to initiate the
    RPC call when conditions are right. A problem arises when we want to
    free the layout segment from inside an inode->i_lock section (e.g. in
    pnfs_clear_request_commit()), since we cannot sleep.

    The workaround is to move the actual call to pnfs_send_layoutreturn()
    to pnfs_put_layout_hdr(), which doesn't have this restriction.

    Pull final vfs updates from Al Viro:

    - The ->i_mutex wrappers (with small prereq in lustre)

    - a fix for too early freeing of symlink bodies on shmem (they need to
    be RCU-delayed) (-stable fodder)

    - followup to dedupe stuff merged this cycle

    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
    vfs: abort dedupe loop if fatal signals are pending
    make sure that freeing shmem fast symlinks is RCU-delayed
    wrappers for ->i_mutex access
    lustre: remove unused declaration
