  • 1146f7e2d   ntfs: fix ntfs_test_inode and ntfs_init_locked_inode function type ... Browse Code »

    Clang's Control Flow Integrity (CFI) is a security mechanism that can help
    prevent JOP chains, deployed extensively in downstream kernels used in
    Android.

    Its deployment is hindered by mismatches in function signatures. For this
    case, we make callbacks match their intended function signature, and cast
    parameters within them rather than casting the callback when passed as a
    parameter.

    When running `mount -t ntfs ...` we observe the following trace:

  • db6172c41   fs: cleanup slight list_entry abuse ... Browse Code »

    list_entry is just a wrapper for container_of, but it is arguably
    wrong (and slightly confusing) to use it when the pointed-to struct
    member is not a struct list_head. Use container_of directly instead.

  • a9185b41a   pass writeback_control to ->write_inode ... Browse Code »

    This gives the filesystem more information about the writeback that
    is happening. Trond requested this for the NFS unstable write handling,
    and other filesystems might benefit from this too by beeing able to
    distinguish between the different callers in more detail.

    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!
