  • 0e1edbd99   [XFS] Fix xfs_free_extent related NULL pointer dereference. ... Browse Code »

    We recently fixed an out-of-space deadlock in XFS, and part of that fix
    involved the addition of the XFS_ALLOC_FLAG_FREEING flag to some of the
    space allocator calls to indicate they're freeing space, not allocating
    it. There was a missed xfs_alloc_fix_freelist condition test that did not
    correctly test "flags". The same test would also test an uninitialised
    structure field (args->userdata) and depending on its value either would
    or would not return early with a critical buffer pointer set to NULL.

    This fixes that up, adds asserts to several places to catch future botches
    of this nature, and skips sections of xfs_alloc_fix_freelist that are
    irrelevent for the space-freeing case.

  • d210a28cd   [XFS] In actual allocation of file system blocks and freeing extents, the ... Browse Code »

    transaction within each such operation may involve multiple locking of AGF
    buffer. While the freeing extent function has sorted the extents based on
    AGF number before entering into transaction, however, when the file system
    space is very limited, the allocation of space would try every AGF to get
    space allocated, this could potentially cause out-of-order locking, thus
    deadlock could happen. This fix mitigates the scarce space for allocation
    by setting aside a few blocks without reservation, and avoid deadlock by
    maintaining ascending order of AGF locking.

    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!
