  • bcc54e2a6   jffs2: fix up rb_root initializations to use RB_ROOT ... Browse Code »

    jffs2 uses rb_node = NULL; to zero rb_root.

    The problem with this is that 17d9ddc72fb8bba0d4f678 ("rbtree: Add
    support for augmented rbtrees") in the linux-next tree adds a new field
    to that struct which needs to be NULL as well. This patch uses RB_ROOT
    as the intializer so all of the relevant fields will be NULL'd.

  • 4c41bd0ec   [JFFS2] fix mount crash caused by removed nodes ... Browse Code »

    At scan time we observed following scenario:

    node A inserted
    node B inserted
    node C inserted -> sets overlapped flag on node B

    node A is removed due to CRC failure -> overlapped flag on node B remains

    while (tn->overlapped)
    tn = tn_prev(tn);

    ==> crash, when tn_prev(B) is referenced.

    When the ultimate node is removed at scan time and the overlapped flag
    is set on the penultimate node, then nothing updates the overlapped
    flag of that node. The overlapped iterators blindly expect that the
    ultimate node does not have the overlapped flag set, which causes the
    scan code to crash.

    It would be a huge overhead to go through the node chain on node
    removal and fix up the overlapped flags, so detecting such a case on
    the fly in the overlapped iterators is a simpler and reliable
    solution.

  • fcf3cafb3   [JFFS2] Remove another bogus optimisation in jffs2_add_tn_to_tree() ... Browse Code »

    We attempted to insert new nodes into the tree by just using
    rb_replace_node to let them replace an earlier node which they
    completely overlapped. However, that could place the new node into the
    wrong place in the tree, since its start could be node only before the
    start of the victim, but before the node _before_ the victim in the tree
    (if that previous node actually ends _after_ the new node, thus isn't
    entirely overlapped and wasn't itself chosen to be the victim).

  • 96dd8d25d   [JFFS2] Remove broken insert_point optimisation in jffs2_add_tn_to_tree() ... Browse Code »

    The original code would remember, during the first pass over the tree,
    a suitable place to start the insertion from when we eventually come
    to add a new node.

    The optimisation was broken, and we sometimes ended up inserting a new
    node in the wrong place because we started the insertion from the wrong
    point.

    Just ditch the optimisation and start the insertion from the root of the
    tree, for now. I'll try it again when I'm feeling cleverer.

  • df8e96f39   [JFFS2] Improve read_inode memory usage, v2. ... Browse Code »

    We originally used to read every node and allocate a jffs2_tmp_dnode_info
    structure for each, before processing them in (reverse) version order
    and discarding the ones which are obsoleted by later nodes.

    With huge logfiles, this behaviour caused memory problems. For example, a
    file involved in OLPC trac #1292 has 1822391 nodes, and would cause the XO
    machine to run out of memory during the first stage of read_inode().

    Instead of just inserting nodes into a tree in version order as we find
    them, we now put them into a tree in order of their offset within the
    file, which allows us to immediately discard nodes which are completely
    obsoleted.

    We don't use a full tree with 'fragments' pointing to the real data
    structure, as we do in the normal fragtree. We sort only on the start
    address, and add an 'overlapped' flag to the tmp_dnode_info to indicate
    that the node in question is (partially) overlapped by another.

    When the scan is complete, we start at the end of the file, adding each
    node to a real fragtree as before. Where the node is non-overlapped, we
    just add it (it doesn't matter that it's not the latest version; there is
    no overlap). When the node at the end of the tree _is_ overlapped, we sort
    it and all its overlapping nodes into version order and then add them to
    the fragtree in that order.

    This 'early discard' reduces the peak allocation of tmp_dnode_info
    structures from 1.8M to a mere 62872 (3.5%) in the degenerate case
    referenced above.

    This version of the patch also correctly rememembers the highest node
    version# seen for an inode when it's scanned.

  • 10731f830   [JFFS2] fix buffer sise calculations in jffs2_get_inode_nodes() ... Browse Code »

    In read inode we have an optimization which prevents one
    min. I/O unit (e.g. NAND page) to be read more then once.

    Namely, at the beginning we do not know which node type we read,
    so we read so we assume we read the directory entry, because it
    has the smallest node header. When we read it, we read up to the
    next min. I/O unit, just because if later we'll need to read more,
    we already have this data.

    If it turns out to be that the node is not directory entry, and
    we need more data, and we did not read it because it sits in the
    next min. I/O unit, we read the whole next (or several next)
    min. I/O unit(s). And if it happens to be that we read a data node,
    and we've read part of its data, we calculate partial CRC.
    So if later we need to check data CRC, we'll only read the rest
    of the data from further min. I/O units and continue CRC checking.

    This code was a bit messy and buggy. The bug was that it assumed
    relatively large min. I/O unit, so that the largest node header
    could overlap only one min. I/O unit boundary.

    This parch clean-ups the code a bit and fixes this bug.
    The patch was not tested on flash with small min. I/O unit, like
    NOR-ECC, nut it was tested on NAND with 512 bytes NAND page, so
    it at least does not break NAND. It was also tested with mtdram
    so it should not break NOR.

    It ensures to release acl cache when inode is cleared.
