| Summary: Data copying in the presence of I/O Errors | |
dd_rescue helps when nothing else can: your disk has crashed and you try to copy it over to another one. While standard Unix tools like cp, cat, and dd will "abort" on every I/O error, dd_rescue does not. dd_rescue has many other goodies; optimization by using large blocks as long as no errors are in sight and falling back to small ones; reverse direction copy; splice in-kernel zerocopy; O_DIRECT support; preallocation with fallocate(). dd_rescue also provides data protection features by overwriting files or disks with fast random numbers, optionally multiple times. dd_rescue supports plugins; currently a hash, an lzo and a crypt plugin exist, supporting on the fly hash/HMAC calculation/validation, lzo de/compression and de/encryption. The lzo plugin is packaged in the dd_rescue-lzo, the crypt plugin in the dd_rescue-crypt subpackage.
GPL-2.0-only OR GPL-3.0-only
* Mon Jan 20 2025 kurt@garloff.de
- Update to dd_rescue-1.99.20:
* Fix an overrun in sparse block detection.
* Fix an off-by-one memory handling issue in ddr_lzo, resulting
in breakage on s390x. (Surprisingly, glibc memory allocator
was graceful on most architectures.)
* Better test coverage, including chains with sparse files.
* Documented (and somewhat cleaner) design of handling sparse
files through chains of plugins.
* Test and support compression+encryption (and reverse
decryption+decompression) chains.
* Improved debug output, including numbering plugins.
* Mon Jan 06 2025 kurt@garloff.de
- Update to dd_rescue-1.99.19:
* ddr_crypt: Clean hole support with and without skiphole.
(This works cleanly only for CTR and ECB modes.)
* ddr_crypt: Fix backwards copies including holes. Note that
this could result in different files from the forward copies
before (bug). Add test case for the latter.
* Many more testcases for sparse files with plugins: Also use
odd sizes and holes at the beginning and end of the file.
* Also skip over holes with -a when copying in reverse dir.
* Allow setting unsparse and some other flags for ddr_null for
testing.
* Fix lzma compression with hole at the end.
* Warn on lzma buf error (was debug msg only before).
* Sun Dec 29 2024 kurt@garloff.de
- Update to dd_rescue-1.99.18:
* Cleanup libddr_lzma flags and memory handling; support sparse
input. Default preset to 4 now.
* Detect sparse output from unsparse plugins (decompression
and decryption may benefit from this).
* Testcase for (de)compression with sparse files.
* Fix calchmac.py for Python 3.12, so HMAC tests succeed again.
* Rationalize log level handling (control by -q, -v, -E).
* Move cache prefetching fomr plugins to main program.
* Sat Nov 02 2024 kurt@garloff.de
- Update to dd_rescue-1.99.17:
* Plugin libddr_lzma.so: LZMA2/xz de/compression from Dmitrii
Ivanov. Covering the other end of the spectrum of LZO, with
high compression ratios at high CPU cost for compression.
(Decompression is cheap for both.)
* Code review and streamlining for dd_rescue integration by
Kurt Garloff.
* Sun Sep 29 2024 kurt@garloff.de
- Update to dd_rescue-1.99.16:
* Refactoring: Move CPU feature detection to archdep.c.
* libddr_cypt: Support passing in password via pipe and passfd=
* Add testcase for this
* Support sha256 acceleration on x86-64 and armv8.
* Improve detection of armv8 crypto (aes) acceleration (32bit).
* Tue Sep 17 2024 kurt@garloff.de
- Update to dd_rescue-1.99.15:
* Build issue: Detect pread64() and pwrite64() support separately
and provide individual replacement functions.
Thanks to David Geiger for reporting (Mageia).
* Bugfix: printstatus() would not be called with odd offsets,
resulting in missing progress report and missing sync (-y) and
write throttling (-C).
* Optimization: Some unrolling for the hash functions gives up to
10% better performance (on Zen4).
* Optimization: Rationalize prefetching for hash functions and
clear memory after using (avoid cleartext data on the stack).
* Optimization: Save function calls for fault injection and for
graph updates when unneeded.
* Usability: Better handle progress update frequency.
* Build improvement: Add -target linux-aarch64/arm-android28
automatically where needed.
* Drop: ddr-autoconf-no-fortify.diff (included upstream).
* Thu Aug 22 2024 kurt@garloff.de
- Avoid setting _FORTIFY_SOURCE in configure script, it may
conflict with flags passed in otherwise (e.g. rpmbuild).
* Thu Aug 22 2024 kurt@garloff.de
- Update to dd_rescue-1.99.14:
* Drop patches dd_rescue-u-emptyout-segfault.diff:,
dd_rescue-fuzz-test-more-err.diff:,
dd_rescue-md5-unaligned-armv7.diff:,
dd_rescue-ossl3-evpcipherctx.diff: All integrated upstream.
* Fix detection of LFS function availability for musl.
* Include headers and settings to make it work on musl.
* Replaced basename() with mybasename.h.
* Prefetch lookup table for sha hashing.
* Fix verbose output when falling back to small blocksize.
* Fix clearing of errno (unaligned writes at EOF on musl)
- Final tarball with fixes for Android Makefiles.
* Mon Aug 12 2024 kurt@garloff.de
- dd_rescue-u-emptyout-segfault.diff: Prevent (cosmetic) segfault
in cleanup path with option -u and empty output file name.
* Sun Mar 03 2024 kurt@garloff.de
- dd_rescue-md5-unaligned-armv7.diff: gcc-12 does make unaligned
accesses on armv7 work sometimes, which breaks a configure test
and then makes the make check fail with SIGBUS when using hash
after lzo compression. Hardcode knowledge about armv7.
- Drop %setup (not needed if using %autosetup, thanks Valentin!)
- Mention [bsc#1219882], as suggested by Valentin Lefebvre.
* Thu Feb 29 2024 kurt@garloff.de
- Fix openssl version detection for 3.0.x.
- dd_rescue-ossl3-evpcipherctx.diff: There's an additional field
in the (private) struct _evp_cipher_ctx_st in openssl-3 since
3.0.6, which makes a difference on 32bit. (On 64bit, the effect
is hidden by the compiler's alignment rules.)
* Wed Feb 28 2024 kurt@garloff.de
- Specify libopenssl-devel as BuildRequirements. This will select
openssl-3 on new distributions.
This fixes [bsc#1219882].
* Fri Mar 17 2023 kurt@garloff.de
- Readd detached signature.
* Tue Feb 28 2023 Dirk Müller <dmueller@suse.com>
- temporarily remove not-really-detached-signature
* Fri Feb 24 2023 kurt@garloff.de
- Update to 1.99.13:
* Drop fuzz-lzo-* patches, as they have been merged upstream.
* Allow overriding strip binary (not used in this build).
* Make -fanalyzer more happy: abort() and assert()ions to ensure
we always react to failed memory allocations.
* ddr_hash: Support reading/writing checksums from stdin/out "-".
* Fix aliasing issue with XORN function (in aes.h), spotted by
gcc-13: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108695
Drop workaround from Martin Liška again.
* Higher optimization level for aes.c driver is beneficial for
key setup speed.
* Wed Feb 08 2023 Martin Liška <mliska@suse.cz>
- Disable strict aliasing due to its violation:
https://sourceforge.net/p/ddrescue/tickets/6/
* Tue Dec 27 2022 Ludwig Nussel <lnussel@suse.com>
- Replace transitional %usrmerged macro with regular version check (boo#1206798)
* Tue Jul 26 2022 kurt@garloff.de
- Update to dd_rescue-1.99.12:
* Works with openssl-3.0 now (using EVP_Cipher_Init to set IV).
* openssl-1.1 performs significantly better so we keep building
against it if available.
* nosalthdr option for libddr_crypt for compatibility with
openssl-3, no longer writing header when salt is passed.
* ARMv7 crypto support successfully compiles with clang now.
- Drop no-python2.patch (included in dd_rescue-1.99.12).
