  • 534667102   jffs2: fix up error handling for insert_inode_locked ... Browse Code »

    after 250df6ed274d767da844a5d9f05720b804240197
    (fs: protect inode->i_state with inode->i_lock), insert_inode_locked()
    no longer returns the inode with I_NEW set on failure. However,
    the error handler still calls unlock_new_inode() on failure,
    which does a WARN_ON if I_NEW is not set, so any failure spews
    a lot of warnings.

    We can just drop the unlock_new_inode() if insert_inode_locked()
    fails here.

  • 92abc475d   jffs2: implement mount option parsing and compression overriding ... Browse Code »

    Currently jffs2 has compile-time constants (and .config options)
    controlling whether or not the various compression/decompression
    drivers are built in and enabled. This is fine for embedded
    systems, but it clashes with distribution kernels. Distro kernels
    tend to turn on everything; this causes OpenFirmware to fall
    over, as it understands ZLIB-compressed inodes. Booting a kernel
    that has LZO compression enabled, writing to the boot partition,
    and then rebooting causes OFW to fail to read the kernel from
    the filesystem. This is because LZO compression has priority
    when writing new data to jffs2, if LZO is enabled.

    This patch adds mount option parsing, and a single supported
    option ("compr=none"). This adds the flexibility of being
    able to specify which compressor overrides on a per-superblock
    basis. For now, we can simply disable compression;
    additional flexibility coming soon.

    v2: kill some printks, and implement show_options as suggested
    by Artem Bityutskiy.

  • aa3857295   fs: pass exact type of data dirties to ->dirty_inode ... Browse Code »

    Tell the filesystem if we just updated timestamp (I_DIRTY_SYNC) or
    anything else, so that the filesystem can track internally if it
    needs to push out a transaction for fdatasync or not.

    This is just the prototype change with no user for it yet. I plan
    to push large XFS changes for the next merge window, and getting
    this trivial infrastructure in this window would help a lot to avoid
    tree interdependencies.

    Also remove incorrect comments that ->dirty_inode can't block. That
    has been changed a long time ago, and many implementations rely on it.

  • 65e5a0e18   jffs2: Dynamically choose inocache hash size ... Browse Code »

    When JFFS2 is used for large volumes, the mount times are quite long.
    Increasing the hash size provides a significant speed boost on the OLPC
    XO-1 laptop.

    Add logic that dynamically selects a hash size based on the size of
    the medium. A 64mb medium will result in a hash size of 128, and a 512mb
    medium will result in a hash size of 1024.

  • 2c27c65ed   check ATTR_SIZE contraints in inode_change_ok ... Browse Code »

    Make sure we check the truncate constraints early on in ->setattr by adding
    those checks to inode_change_ok. Also clean up and document inode_change_ok
    to make this obvious.

    As a fallout we don't have to call inode_newsize_ok from simple_setsize and
    simplify it down to a truncate_setsize which doesn't return an error. This
    simplifies a lot of setattr implementations and means we use truncate_setsize
    almost everywhere. Get rid of fat_setsize now that it's trivial and mark
    ext2_setsize static to make the calling convention obvious.

    Keep the inode_newsize_ok in vmtruncate for now as all callers need an
    audit for its removal anyway.

    Note: setattr code in ecryptfs doesn't call inode_change_ok at all and
    needs a deeper audit, but that is left for later.

    Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more

    Stop the JFFS2 filesystem from using iget() and read_inode(). Replace
    jffs2_read_inode() with jffs2_iget(), and call that instead of iget().
    jffs2_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

    jffs2_do_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

    [In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem
    with standard permissions on newly-created inodes, when POSIX ACLs are
    enabled. This cleans it up...]

    The attached patch separate jffs2_init_acl() into two parts.

    The one is jffs2_init_acl_pre() called from jffs2_new_inode().
    It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL
    objects associated with the new inode just before when inode meta
    infomation is written to the medium.

    The other is jffs2_init_acl_post() called from jffs2_symlink(),
    jffs2_mkdir(), jffs2_mknod() and jffs2_do_create().
    It actually writes in-memory ACL objects into the medium next to
    the success of writing meta-information.

    In the current implementation, we have to write a same inode meta
    infomation twice when inode->i_mode is updated by the default ACL.
    However, we can avoid the behavior by putting an updated i_mode
    before it is written at first, as jffs2_init_acl_pre() doing.

    I've bisected the deadlock when many small appends are done on jffs2 down to
    this commit:

    commit 6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2
    Author: Nick Piggin
    Date: Sun May 6 14:49:04 2007 -0700

    mm: make read_cache_page synchronous

    Ensure pages are uptodate after returning from read_cache_page, which allows
    us to cut out most of the filesystem-internal PageUptodate calls.

    I didn't have a great look down the call chains, but this appears to fixes 7
    possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in
    ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in
    block2mtd. All depending on whether the filler is async and/or can return
    with a !uptodate page.

    It introduced a wait to read_cache_page, as well as a
    read_cache_page_async function equivalent to the old read_cache_page
    without any callers.

    Switching jffs2_gc_fetch_page to read_cache_page_async for the old
    behavior makes the deadlocks go away, but maybe reintroduces the
    use-before-uptodate problem? I don't understand the mm/fs interaction
    well enough to say.
