Check for end of the input buffer when skipping over the filename field in
the .gz file header.

Decompressors: include in

2011-01-13T16:03:23+00:00

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

Decompressors: get rid of set_error_fn() macro

2011-01-13T16:03:23+00:00

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.

lzma/gzip: fix potential oops when input data is truncated

2009-09-24T14:21:05+00:00

If the lzma/gzip decompressors are called with insufficient input data
(len > 0 & fill = NULL), they will attempt to call the fill function to
obtain more data, leading to a kernel oops.

lib/decompress_*: only include if STATIC is not defined

2009-08-07T17:39:56+00:00

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.

bzip2/lzma/gzip: fix comments describing decompressor API

2009-08-07T17:39:56+00:00

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.

kmemtrace, kbuild: fix slab.h dependency problem in lib/decompress_inflate.c

2009-04-03T10:21:36+00:00

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: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.

bzip2/lzma: fix decompress_inflate.c vs multi-block-with-embedded-filename

2009-01-08T23:10:19+00:00

Impact: Bug fix

Fix gunzip uncompression, so that it also works with files with
embedded filenames that are larger than one block.

bzip2/lzma: fix constant in decompress_inflate

2009-01-08T23:09:12+00:00

Impact: Cleanup

Fix constant 0x8100 /* 32K */; according to Alain the value 0x8100 was
left over test code to test misalignment, the correct value is indeed
0x8000 == 32K.
