Xlunzip is similar to lunzip, but it uses the lzip_decompress +linux module as a backend. Xlunzip tests the module for stream, +buffer-to-buffer and mixed decompression modes, including in-place +decompression (using the same buffer for input and output). You can use +xlunzip to verify that the module produces correct results when +decompressing single member files, multimember files, or the +concatenation of two or more compressed files. Xlunzip can be used with +unzcrash to test the robustness of the module to the decompression of +corrupted data. + +Note that the in-place decompression of concatenated files can't be +guaranteed to work because an arbitrarily low compression ratio of the +last part of the data can be achieved by appending enough empty +compressed members to a file. + +The xlunzip tarball contains a copy of the lzip_decompress module and +can be compiled and tested without downloading or applying the patch to +the kernel. + +My lzip patch for linux can be found at +http://download.savannah.gnu.org/releases/lzip/kernel/ + +Lzip related components in the kernel +===================================== + +The lzip_decompress module in lib/lzip.c provides a versatile lzip +decompression function able to do buffer to buffer decompression or +stream decompression with fill and flush callback functions. The usage +of the function is documented in include/linux/lzip.h. + +For decompressing the kernel image, initramfs, and initrd, there is a +wrapper function in lib/decompress_lunzip.c providing the same common +interface as the other decompress_*.c files, which is defined in +include/linux/decompress/generic.h. + + +Copyright (C) 2016-2018 Antonio Diaz Diaz. + +This file is free documentation: you have unlimited permission to copy, +distribute and modify it. + +The file Makefile.in is a data file used by configure to produce the +Makefile. It has the same copyright owner and permissions that configure +itself. |
