  • 2b6b5caa6   Decompressors: include <linux/slab.h> in <linux/decompress/mm.h> ... Browse Code »

    Currently users of mm.h need to include to use the macros
    malloc() and free() provided by mm.h. This fixes it.

  • 93685ad24   Decompressors: get rid of set_error_fn() macro ... Browse Code »

    set_error_fn() has become a useless complication after c1e7c3ae59
    ("bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure") fixed
    the use of error() in malloc(). Only decompress_unlzma.c had some use for
    it and that was easy to change too.

    This also gets rid of the static function pointer "error", which
    should have been marked as __initdata.

  • 9e5cf0ca2   lib/decompress_*: only include <linux/slab.h> if STATIC is not defined ... Browse Code »

    These includes were added by 079effb6933f34b9b1b67b08bd4fd7fb672d16ef
    ("kmemtrace, kbuild: fix slab.h dependency problem in
    lib/decompress_inflate.c") to fix the build when using kmemtrace. However
    this is not necessary when used to create a compressed kernel, and
    actually creates issues (brings a lot of things unavailable in the
    decompression environment), so don't include it if STATIC is defined.

  • daeb6b6fb   bzip2/lzma/gzip: fix comments describing decompressor API ... Browse Code »

    Fix and improve comments in decompress/generic.h that describe the
    decompressor API. Also remove an unused definition, and rename INBUF_LEN
    in lib/decompress_inflate.c to conform to bzip2/lzma naming.

    Impact: fix build

    lib/decompress_inflate.c depends on slab.h without including it:

    CC lib/decompress_inflate.o
    lib/decompress_inflate.c: In function ‘gunzip’:
    lib/decompress_inflate.c:45: error: implicit declaration of function ‘kmalloc’
    lib/decompress_inflate.c:45: warning: assignment makes pointer from integer without a cast
    lib/decompress_inflate.c:57: warning: assignment makes pointer from integer without a cast
    lib/decompress_inflate.c:65: warning: assignment makes pointer from integer without a cast
    lib/decompress_inflate.c:71: warning: assignment makes pointer from integer without a cast
    lib/decompress_inflate.c:154: error: implicit declaration of function ‘kfree’
    make[1]: *** [lib/decompress_inflate.o] Error 1
    make: *** [lib/] Error 2

    It gets included implicitly currently - but this will not be the
    case with upcoming kmemtrace changes.

  • bc22c17e1   bzip2/lzma: library support for gzip, bzip2 and lzma decompression ... Browse Code »

    Impact: Replaces inflate.c with a wrapper around zlib_inflate; new library code

    This is the first part of the bzip2/lzma patch

    The bzip patch is based on an idea by Christian Ludwig, includes support for
    compressing the kernel with bzip2 or lzma rather than gzip. Both
    compressors give smaller sizes than gzip. Lzma's decompresses faster
    than bzip2.

    It also supports ramdisks and initramfs' compressed using these two
    compressors.

    The functionality has been successfully used for a couple of years by
    the udpcast project

    This version applies to "tip" kernel 2.6.28

    This part contains:
    - changed inflate.c to accomodate rest of patch
    - implementation of bzip2 compression (not used at this stage yet)
    - implementation of lzma compression (not used at this stage yet)
    - Makefile routines to support bzip2 and lzma kernel compression
