  • be629c62a   Fix directory hardlinks from deleted directories ... Browse Code »

    When a directory is deleted, we don't take too much care about killing off
    all the dirents that belong to it — on the basis that on remount, the scan
    will conclude that the directory is dead anyway.

    This doesn't work though, when the deleted directory contained a child
    directory which was moved *out*. In the early stages of the fs build
    we can then end up with an apparent hard link, with the child directory
    appearing both in its true location, and as a child of the original
    directory which are this stage of the mount process we don't *yet* know
    is defunct.

    To resolve this, take out the early special-casing of the "directories
    shall not have hard links" rule in jffs2_build_inode_pass1(), and let the
    normal nlink processing happen for directories as well as other inodes.

    Then later in the build process we can set ic->pino_nlink to the parent
    inode#, as is required for directories during normal operaton, instead
    of the nlink. And complain only *then* about hard links which are still
    in evidence even after killing off all the unreachable paths.

  • 1d5cfdb07   tree wide: use kvfree() than conditional kfree()/vfree() ... Browse Code »

    There are many locations that do

    if (memory_was_allocated_by_vmalloc)
    vfree(ptr);
    else
    kfree(ptr);

    but kvfree() can handle both kmalloc()ed memory and vmalloc()ed memory
    using is_vmalloc_addr(). Unless callers have special reasons, we can
    replace this branch with kvfree(). Please check and reply if you found
    problems.

  • 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.

  • c00c310ea   [JFFS2] Tidy up licensing/copyright boilerplate. ... Browse Code »

    In particular, remove the bit in the LICENCE file about contacting
    Red Hat for alternative arrangements. Their errant IS department broke
    that arrangement a long time ago -- the policy of collecting copyright
    assignments from contributors came to an end when the plug was pulled on
    the servers hosting the project, without notice or reason.

    We do still dual-license it for use with eCos, with the GPL+exception
    licence approved by the FSF as being GPL-compatible. It's just that nobody
    has the right to license it differently.

  • aa98d7cf5   [JFFS2][XATTR] XATTR support on JFFS2 (version. 5) ... Browse Code »

    This attached patches provide xattr support including POSIX-ACL and
    SELinux support on JFFS2 (version.5).

    There are some significant differences from previous version posted
    at last December.
    The biggest change is addition of EBS(Erase Block Summary) support.
    Currently, both kernel and usermode utility (sumtool) can recognize
    xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype.

    In addition, some bugs are fixed.
    - A potential race condition was fixed.
    - Unexpected fail when updating a xattr by same name/value pair was fixed.
    - A bug when removing xattr name/value pair was fixed.

    The fundamental structures (such as using two new nodetypes and exclusion
    mechanism by rwsem) are unchanged. But most of implementation were reviewed
    and updated if necessary.
    Espacially, we had to change several internal implementations related to
    load_xattr_datum() to avoid a potential race condition.

    Fix fairly sad NOR-specific bug - during FS building ic->scan_dents
    isn't zero, but jffs2_mark_node_obsolete() migt be called it tries to
    finde the ic corresponding to ref - this requires ic->scan_dents = 0.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
