commit 0eff79b00ba591400f0a6afde908647a83acbf93 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 17:09:39 2019 -0800 debian: Prepare for upload commit 116a21b293479f50f8ce239ef74561a0359521c0 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 17:08:20 2019 -0800 debian/xz-utils: Remove old NEWS.Debian This contains advice from 2010 about upgrading from a very early version of the package. It should not be relevant for new installations or for people upgrading from more recent versions, so remove the old news and avoid some clutter. commit 247c80e1191dc91b054a83964afa4d4332107bd2 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 17:06:41 2019 -0800 debian/control: New Debian policy version commit 0106f555736c5a94052b758cc09f7ca4ac40a454 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:54:58 2019 -0800 debian/watch: Download upstream source more securely Use https instead of http for transport for transport-layer privacy and integrity protection. More importantly, specify pgpsigurlmangle and a signing key to allow "uscan" to check that the tarball was genuinely released by Lasse Collin. Based on advice from Policy 4.11. While we're here, use the XZ compressed tarball, since it's a little smaller. commit a9c81252e0db470509cb4f618ffeb7c12d4ed37a Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:41:56 2019 -0800 debian/control: Follow current policy for Priority field Policy 2.5 explains: The priority of a package is determined solely by the functionality it provides directly to the user. The priority of a package should not be increased merely because another higher-priority package depends on it and: extra This priority is deprecated. Use the optional priority instead. This means we can treat liblzma5 and xzdec as optional now. commit d32587c9bc981ad0430f4ee6fcd60eb38ba60a0d Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:38:54 2019 -0800 debian/copyright: Use https URL for format According to Debian policy's upgrading checklist, the https form of the copyright-format URL is now allowed and preferred in the Format field. commit de2367985e1765c25e98f31053e1e3017ab3133f Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:27:23 2019 -0800 debian/copyright: Update based on upstream changes No major changes, but a few minor ones. commit 8b5e17be5de2ecd7b6b5c1583372fefa6eb1f385 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:21:09 2019 -0800 debian: Use https for upstream URLs tukaani.org once didn't support TLS, but nowadays it does. Use the https URL so that people clicking it get better privacy and integrity support. The latter is especially important for the website of a project like this so that people don't download tampered code. commit fa45221b588c2262f912107a4802cf1fa347f217 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sun Jan 27 16:13:43 2019 -0800 debian/control: Vcs-Git: https://repo.or.cz/r/xz/debian Alioth (git.debian.org) has been shut down. Point to a copy of the packaging repository on repo.or.cz that should be more stable over time. Another advantage is that this URL uses https, so it has better privacy and integrity properties. Fixes: https://bugs.debian.org/826382 commit 3ed34568d0b311a6998a1aa8f6352b13849483ed Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sat Jun 23 17:44:04 2012 -0500 debian/control: xz-utils is not pseudo-essential any more Since dpkg 1.16.4~6 (libdpkg: Add liblzma compression support, 2012-06-07), the xz command is no longer needed in a minimal Debian system. Based on its list of reverse-dependencies, it is even safe to lower the priority to optional. Let's make it "standard", since it is not part of the traditional Unix toolset but is a useful component even in reasonably small character-mode systems.

Requested-by: Josh Triplett <josh@joshtriplett.org> commit 8ab1be2e92f45ad9a10d6179107067b27e24a432 Author: Ximin Luo <infinity0@debian.org> Date: Wed Jun 28 17:10:00 2017 +0000 debian/rules: Use /bin/sh as POSIX shell regardless of build environment While working on the “reproducible builds” effort [1], we have noticed that xz-utils could not be built reproducibly. When dash is the default shell, the configure script m4/posix-shell.m4 will select /bin/bash as the “conforming POSIX shell”. When bash is the default shell, /bin/sh will be selected. The binary package currently in sid on amd64 uses /bin/bash. As bash is currently Essential:yes (#103284), this is probably not a problem. But I wonder if they would not be troubles if the package was built on an environment were bash is the default shell, but later installed on a system where /bin/dash is /bin/sh. So for reproducibility and safety reason, it would be best if the selected path to the shell would not depend on the build environment.

(This is a hypothetical scenario --- Debian librpm does not provide a static library.) If liblzma uses unpatched lzma_code() from XZ Utils >= 5.0, then during calls to librpm that try to compress or decompress an xz-compressed RPM, lzma_code’s reserved field checks will overflow the buffer and segfault. If liblzma uses the modified version of lzma_code() which asks libdl if liblzma.so.2 is resident and refrains from checking reserved fields past the end of the old lzma_stream struct when the answer is "yes", the behavior is no better. The dynamic library liblzma.so.2 is _not_ resident, so lzma_code() dutifully reads reserved fields past the end of the buffer --- segfault. So the only safe behavior in the static library is to unconditionally disable checks that might break for callers we want to continue to support. The new "./configure --enable-liblzma2-compat" option implements all three sets of semantics: - "./configure --disable-liblzma2-compat" means to check the full set of reserved fields unconditionally. You can use this to check how your application would behave with the unpatched library. - "./configure --enable-liblzma2-compat=auto" means to skip checks of reserved fields past the old end of struct lzma_stream when liblzma.so.2 is resident. If a DSO built against liblzma2 shares the process image, the ABI-incompatible checks are skipped for safety, whereas in the usual case when no such DSO is resident, the full set of checks is run to help application developers remember to zero all reserved fields. - "./configure --enable-liblzma2-compat" makes liblzma skip the ABI-incompatible checks unconditionallty. You can use this if you want your copy of liblzma to be usable by static libraries that were built against the old library. Patch-Name: liblzma-make-dlopen-based-liblzma2-compatibility-opt.patch Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> commit 00a784e9a4ab33ebb0a42e35444c8b25a3a36bda Author: Jonathan Nieder <jrnieder@gmail.com> Date: Thu May 17 18:49:00 2012 -0500 liblzma: skip ABI-incompatible check when liblzma.so.2 is loaded When liblzma started using ELF symbol versioning at the same time as a soname bump (2 → 5) and a small increase in the reserved space at the end of the lzma_stream structure checked by lzma_code, introducing an unversioned compatibility symbol to ease the transition seemed like a great idea. After all: - most applications only use one version of the library (liblzma.so.2 or liblzma.so.5) and would obviously work fine - applications linking to the new version of the library (liblzma.so.5) should use the default, versioned lzma_code symbol so errors initializing the reserved space can be noticed - symbol versioning should ensure application/library mixtures independently making use of both versions of the library also work. Calls using the unversioned symbol names would be resolved using the old symbol from liblzma.so.2 or the compatibility symbol from liblzma.so.5, avoiding segfaults and spurious LZMA_OPTIONS_ERROR errors. - application/library mixtures using both versions of the library and passing lzma_stream objects between the two would break, but that was never supposed to be supported, anyway. Three toolchain bugs dash that plan. Current (2.22) versions of the gold linker cannot be used to build libraries providing versioned and unversioned symbols with the same name. On the other hand, BFD ld doesn't mind. So GNU gold refuses to link versions of liblzma including the compatibility symbol (PR12261): /usr/bin/ld: error: symbol lzma_code has undefined version Annoying, but livable. liblzma with the compatibility symbol just has to be built with BFD ld. More importantly, gold does not support linking to libraries providing versioned and unversioned symbols with the same name. If I link some code to a version of liblzma with the compatibility symbol: ld -o demo demo.o -llzma then the documented behavior, implemented by BFD ld, is to interpret calls to lzma_code as referring to the default version (lzma_code@XZ_5.0). Current versions of GNU gold treat such calls as referring to whichever symbol comes first in liblzma.so.5's symbol table. If the unversioned symbol comes first (and in Debian liblzma5 5.1.1alpha+20110809-3 it does), GNU gold will mislink new applications to use the unversioned compatibility symbol (PR13521): $ ld.gold -o test.gold test.o -llzma $ eu-readelf -s test.gold | grep lzma_code 1: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF lzma_code 5: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF lzma_code There is no warning. Worse, ld.so from glibc unpredictably will sometimes use the versioned symbol to resolve references to the unversioned base version when both are present (PR12977). Clearly no one has been testing mixtures of versioned and unversioned symbols at all, and we cannot trust the symbol resolution process to do anything in particular for them. This patch implements an alternative method to implement the same compatibility goals described above. - No more compatibility symbol. liblzma.so.5 will define lzma_code only once, with version XZ_5.0. - When initializing an lzma_stream object, use dlopen("liblzma.so.2", RTLD_NOLOAD) to detect whether the caller might have been expecting the old ABI, and store that information in the private stream->internal->liblzma2_compat field. - In lzma_code, when checking reserved fields, skip fields past the old end of the lzma_stream structure ifying reserved fields if and only if this->internal->liblzma2_compat is false. That's it. Hopefully this time it will work reliably. Thanks to Eduard Bloch for noticing PR13521 and to Ian Lance Taylor for PR12977.

So the repo above is git-dpm for now. I kept liblzma-make-dlopen-based-liblzma2-compatibility-opt.patch liblzma-skip-ABI-incompatible-check-when-liblzma.so.patch but I think that we shouldn't worry about liblzma2 since it is long gone. Anyway, it is there. The current changelog: | * switch to git-dpm for packaging (closes: #540405) | * New Upstream (closes: #731634) | - no more "xzless error in line 49" (closes: #693537) | - xzgrep -h works (closes: #780268) | * update symbol file I built pixz against it and the internal testsuite passed. I checked out all pristine-tar files from clamav (in the xz format) and the checkout worked.

As it happens, the perl build-dependency is entirely unnecessary. xz-utils only uses the bare perl interpreter, without modules (other than 'warnings' and 'strict'). As such, it has no need for non-Essential facilities, and can rely on the Essential perl-base. In private mail, Jonathan suggested rewriting in awk, but this is unnecessary; you really should just be able to rely on the Essentialness of the perl interpreter here, and the Perl policy sanctions this given that xz-utils is part of the base system. * Remove build-dependency on perl; we use no non-trivial Perl modules so the Essential perl-base is perfectly adequate, and an unadorned build-dependency on perl is problematic for cross-building.

Hopefully most developers on Debian will test using the shared library by default. We could have made this change by keying the behavior on __PIC__, but that seems a little too tricky and inflexible (maybe some platform uses PIC for ordinary static libraries) so instead we build the static and shared libraries in separate configure runs. One subtlety: because the Libs.private setting in the pkgconfig metadata file is only valid in the static build, the static lib is installed after the shared library. commit e6bb16b7fb87a0953eb18bb11e92206172e725f7 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sat Jun 16 05:59:49 2012 -0500 debian/xzdec: configure --disable-liblzma2-compat This just simplifies and shrinks xzdec and lzmadec a little. commit 531fceb2f990896f2d43b174f218c31f92f3c47d Merge: d468549 18a69a2 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sat Jun 16 05:58:50 2012 -0500 Merge branch 'jn/abi' Make the liblzma2-compat trickery more configurable, so we have the option of turning it off for xzdec and the static lib if appropriate to avoid a dependency on libdl. * jn/abi: liblzma: make dlopen()-based liblzma2 compatibility optional commit 18a69a29003d00e171f98ee69170a47f41d4fb80 Author: Jonathan Nieder <jrnieder@gmail.com> Date: Sat Jun 16 05:57:42 2012 -0500 liblzma: make dlopen()-based liblzma2 compatibility optional Suppose I want to build a statically linked program: gcc -static -o app app.c -lrpm -llzma Suppose further that librpm.a was built against a pre-5.0 version of liblzma so it does not allocate as much space for reserved fields at the end of lzma_stream as the current API requires.

So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return LZMA_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. Another situation where the bug can be triggered happens if the uncompressed size is zero bytes and no output space is provided. In this case the decompression can fail even if the whole input file is given to lzma_code().

In particular, after installing a perfectly good liblzma.a, we overwrite it with the copy from the xzdec build with all encoders disabled --- oops. The fix is simple: let the install rule for xzdec run _before_ the normal build. Probably this wasn't noticed before because static linking on Debian is not popular. The xz and lzmainfo commands, shared library, and scripts are all disabled when building xzdec, so this problem only affects the static library.

After all: - most applications only use one version of the library (liblzma.so.2 or liblzma.so.5) and would obviously work fine - applications linking to the new version of the library (liblzma.so.5) should use the default, versioned lzma_code symbol so errors initializing the reserved space can be noticed - symbol versioning should ensure application/library mixtures independently making use of both versions of the library also work. Calls using the unversioned symbol names would be resolved using the old symbol from liblzma.so.2 or the compatibility symbol from liblzma.so.5, avoiding segfaults and spurious LZMA_OPTIONS_ERROR errors. - application/library mixtures using both versions of the library and passing lzma_stream objects between the two would break, but that was never supposed to be supported, anyway. Three toolchain bugs dash that plan. Current (2.22) versions of the gold linker cannot be used to build libraries providing versioned and unversioned symbols with the same name. On the other hand, BFD ld doesn't mind. So GNU gold refuses to link versions of liblzma including the compatibility symbol (PR12261): /usr/bin/ld: error: symbol lzma_code has undefined version Annoying, but livable. liblzma with the compatibility symbol just has to be built with BFD ld. More importantly, gold does not support linking to libraries providing versioned and unversioned symbols with the same name. If I link some code to a version of liblzma with the compatibility symbol: ld -o demo demo.o -llzma then the documented behavior, implemented by BFD ld, is to interpret calls to lzma_code as referring to the default version (lzma_code@XZ_5.0). Current versions of GNU gold treat such calls as referring to whichever symbol comes first in liblzma.so.5's symbol table. If the unversioned symbol comes first (and in Debian liblzma5 5.1.1alpha+20110809-3 it does), GNU gold will mislink new applications to use the unversioned compatibility symbol (PR13521): $ ld.gold -o test.gold test.o -llzma $ eu-readelf -s test.gold | grep lzma_code 1: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF lzma_code 5: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF lzma_code There is no warning. Worse, ld.so from glibc unpredictably will sometimes use the versioned symbol to resolve references to the unversioned base version when both are present (PR12977). Clearly no one has been testing mixtures of versioned and unversioned symbols at all, and we cannot trust the symbol resolution process to do anything in particular for them. This patch implements an alternative method to implement the same compatibility goals described above. - No more compatibility symbol. liblzma.so.5 will define lzma_code only once, with version XZ_5.0. - When initializing an lzma_stream object, use dlopen("liblzma.so.2", RTLD_NOLOAD) to detect whether the caller might have been expecting the old ABI, and store that information in the private stream->internal->liblzma2_compat field. - In lzma_code, when checking reserved fields, skip fields past the old end of the lzma_stream structure ifying reserved fields if and only if this->internal->liblzma2_compat is false. That's it. Hopefully this time it will work reliably. Thanks to Eduard Bloch for noticing PR13521 and to Ian Lance Taylor for PR12977.

When grepping binary files, grep may exit before it has read all the input. In this case, gzip -q returns 2 (eating SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status (e.g. 141). This causes wrong exit status when grepping xz- or bzip2-compressed binary files. The fix checks for the special exit status that indicates SIGPIPE. It uses kill -l which should be supported everywhere since it is in both SUSv2 (1997) and POSIX.1-2008.

Requested-by: Jakub Wilk <jwilk@debian.org> commit 000c7895c66a6ed4e0a6c9427deaf3cf97cb15da Author: Jonathan Nieder <jrnieder@gmail.com> Date: Thu Oct 20 21:17:22 2011 -0500 debian: correct lzma_code@Base rationale debian/patches/abi-liblzma2-compat says: | Applications linked directly to liblzma2 and indirectly to liblzma5 use | the implementation from liblzma5 As Jakub Wilk explained, that doesn't seem to be the case. If a program is linked to two versions of a library, one of which doesn't use versioned symbols, then the symbols from the directly-linked one shadow the indirectly-linked one. Annoyingly, I noticed the same thing last year and then promptly forgot about it. Luckily in cases where liblzma2 wins the right to provide lzma_code(), that just means the lib checks a few fewer reserved fields and the patch is not needed, and in cases where liblzma5 wins, the patch works.

Use an invalid dependency for this, based on an idea by Modestas Vainius from <http://bugs.debian.org/630344>. This way, attempts to build a Debian package linking to the compatibility symbol will be caught early. dpkg-shlibdeps: warning: can't parse dependency liblzma_private_symbols dpkg-shlibdeps: error: invalid dependency got generated: liblzma_private_symbols, libc6 (>= 2.4) dh_shlibdeps: dpkg-shlibdeps -Tdebian/test-prog.substvars debian/test-prog/usr/bin/testme returned exit code 2
