This plugin allows you do de/compress files during recovery copying with dd_rescue using the lzo family of algorithms. lzo algorithms are very fast to decompress and most algorithms are very fast to compress as well -- at the expense of somewhat worse compression than zlib's deflate. The plugin does offer a variety of options to handle corrupted .lzo files with some grace; it does skip over bad blocks (if the block headers are still intact) by default, but does offer an option (nodiscard) to allow to attempt decompression on faulty input, hoping to produce some usable bytes. It can also search for valid block headers after synchronization has been lost due to a corrupt one. The plugin also handles sparse files (files with holes) and supports appending to .lzo files, so it fits neatly into dd_rescue. Some fuzz testing has been applied to the plugin's decompression routines, though more will have to be done to feel confident about feeding untrusted data to the decompressor; the plugin is still young and might expose bugs.

2017-11-10 - firstname.lastname@example.org - Update to 1.99.7: * Work around gentoo dash echo -n breakage (reported by whissi). * Optimize away strlen() calls in format_int.
2017-11-04 - email@example.com - Update to 1.99.7-pre2: * ddr_crypt: compat for openssl enc -md sha256 KDF (openssl 1.1 default) with new opbkdf11 option
2017-11-02 - firstname.lastname@example.org - Update to 1.99.7-pre: * Fix for segfault on multi-overwrite with -2/-3/-4.
2017-09-04 - email@example.com - libddr_hash-round-down-static.diff: Mark inline function static.
2017-08-25 - firstname.lastname@example.org - Update to dd_rescue-1.99.6: * Merge previous SSE2 detection patch from Michael Matz. * Support calculating and validating checksums in the S3 multipart format.
2017-08-10 - email@example.com - Add dd_rescue-i586-sse2.diff to fix dd_rescue compile and runtime problems when GCC defaults to SSE2 also on i586 like with SLE-15.
2017-05-30 - firstname.lastname@example.org - Cleanup a bit the dependencies * Run %configure as separate comand properly in build phase - Remove support for < 12.0 - Add condition for openSSL to build with verison 1.0.0 on Factory
2016-12-29 - email@example.com - Update to dd_rescue-1.99.5: * Merge the two gcc7 patches from Martin Liska. * Better transfer length estimate (thus better progress report) * Optional ratecontrol (throttle transfer speed) * fmt_no was unsafe against undetermined length (pre=0) and visible digit grouping characters, resulting in memory corruption when using a -b logfile. Thanks to Marc Thomas for reporting and debugging! * A few more minor cleanups and bugfixes. * Fix segfault with graph in reverse direction with too large transfer limit. * Fix build with AES but not AVX2 support. - Update to dd_rescue-1.99: * ddr_crypt plugin: Add support for ARMv8 aes hardware acceleration (works as well in 32bit mode). * ddr_crypt: Fix CTR iv initialization. * ddr_crypt: Support for openSSL Salted__ header. * Support ranges in fault injection. * Clean up write retry logic. * Improved documentation, Makefiles and test coverage.
2016-12-23 - firstname.lastname@example.org - Add gcc7-fix-htonl.patch patch.
