  • 01cfb7937   squashfs: be more careful about metadata corruption ... Browse Code »

    Anatoly Trosinenko reports that a corrupted squashfs image can cause a
    kernel oops. It turns out that squashfs can end up being confused about
    negative fragment lengths.

    The regular squashfs_read_data() does check for negative lengths, but
    squashfs_read_metadata() did not, and the fragment size code just
    blindly trusted the on-disk value. Fix both the fragment parsing and
    the metadata reading code.

  • 09cbfeaf1   mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros ... Browse Code »

    PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
    ago with promise that one day it will be possible to implement page
    cache with bigger chunks than PAGE_SIZE.

    This promise never materialized. And unlikely will.

    We have many places where PAGE_CACHE_SIZE assumed to be equal to
    PAGE_SIZE. And it's constant source of confusion on whether
    PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
    especially on the border between fs and mm.

    Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
    breakage to be doable.

    Let's stop pretending that pages in page cache are special. They are
    not.

    The changes are pretty straight-forward:

    - << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

    - page_cache_get() -> get_page();

    - page_cache_release() -> put_page();

    This patch contains automated changes generated with coccinelle using
    script below. For some reason, coccinelle doesn't patch header files.
    I've called spatch for them manually.

    The only adjustment after coccinelle is revert of changes to
    PAGE_CAHCE_ALIGN definition: we are going to drop it later.

    There are few places in the code where coccinelle didn't reach. I'll
    fix them manually in a separate patch. Comments and documentation also
    will be addressed with the separate patch.

  • 846b730e9   Squashfs: Generalise paging handling in the decompressors ... Browse Code »

    Further generalise the decompressors by adding a page handler
    abstraction. This adds helpers to allow the decompressors
    to access and process the output buffers in an implementation
    independant manner.

    This allows different types of output buffer to be passed
    to the decompressors, with the implementation specific
    aspects handled at decompression time, but without the
    knowledge being held in the decompressor wrapper code.

    This will allow the decompressors to handle Squashfs
    cache buffers, and page cache pages.

    This patch adds the abstraction and an implementation for
    the caches.
