libsqfs: Initialize the return value in sqfs_compressor_create

2022-12-01T17:46:52+00:00

Initialize the output compressor pointer to NULL, so if the function fails, the value is propperly initialized to a NULL pointer instead of relying on the function user to initialize it. Signed-off-by: David Oberhollenzer

libsquashfs: get rid of potentially unaligned access and VLAs

2021-06-25T13:12:41+00:00

The same problem with the meta data header again, 16 bit read from a buffer: copy the buffer data into a 16 bit variable instead of casting to something potentially unaligned. Signed-off-by: David Oberhollenzer

Cleanup: move zlib/lz4 code from lib/sqfs/comp/ to lib/

2020-08-04T17:27:42+00:00

The source code of a modified liblz4 and zlib are included with the option to compile them into libsquashfs if they are not available on the system. So far, the source code was included directly in the compressor sub directory within libsqsuashfs. This commit moves the libraries out into the lib directory. Signed-off-by: David Oberhollenzer

Cleanup: Pull compression level parameter out into compressor config

2020-06-04T05:24:52+00:00

Every compressor (except LC4) has a compression level parameter. This commit pulls the compression level field out into the generic configuration structure and applies some code clean ups as a result from this. Signed-off-by: David Oberhollenzer

lzma compressor: support micro management options

2020-06-04T02:57:08+00:00

The LZMA compressor (through the xz-utils library) supports basically the same options for micro management as the XZ compressor. This commit enables support for those options in the compressor, the option parser and adds an option field to the configuration structure. Signed-off-by: David Oberhollenzer

Fix: zstd: actually set the compression level from the options

2020-05-21T19:24:28+00:00

In the zstd compressor, the compression level from the configuration structure wasn't used at all. Instead, the zstd compressor was told to use level 0 and compressor options with that parameter were written to disk. This commit makes sure the level parameter is propperly initialized.
