Lasse Collin f9cf4c05ed CMake: Fix sabotaged Landlock sandbox check.
It never enabled it.

Lasse Collin 49324b711f Build: Use only the generic symbol versioning with NVIDIA HPC Compiler.
This does the previous commit with CMake.

AC_EGREP_CPP uses AC_REQUIRE so the outermost if-commands must
be changed to AS_IF to ensure that things wont break some day.
See 5a5bd7f871.

Lasse Collin c273123ed0 CMake: Use only the generic symbol versioning with NVIDIA HPC Compiler.
It doesn't support the __symver__ attribute or __asm__(".symver ...").
The generic symbol versioning can still be used since it only needs
linker support.

Sergey Kosukhin 096bc0e3f8 liblzma: Fix building with NVHPC (NVIDIA HPC SDK).
NVHPC compiler has several issues that make it impossible to
build liblzma:
  - the compiler cannot handle unions that contain pointers that
    are not the first members;
  - the compiler cannot handle the assembler code in range_decoder.h
    (LZMA_RANGE_DECODER_CONFIG has to be set to zero);
  - the compiler fails to produce valid code for delta_decode if the
    vectorization is enabled, which results in failed tests.

This introduces NVHPC-specific workarounds that address the issues.

Lasse Collin 2ad7fad670 CMake: Disable symbol versioning on non-glibc Linux.
This better matches what configure.ac does. For example, musl has
only basic symbol versioning support:


configure.ac tries to enable symbol versioning only with glibc
so now CMake does the same.

Lasse Collin 82f0c0d39e CMake: Make symbol versioning configurable. 2024-03-15 17:30:50 +02:00
Lasse Collin 45d33bfc45 Build: Style tweaks to configure.ac.
The AC_MSG_ERROR line is overlong anyway as are a few other
AC_MSG_ERROR lines already.

Sergey Kosukhin f56ed6fac6 Build: Let the users override the symbol versioning variant.
There are cases when the users want to decide themselves whether
they want to have the generic (even on GNU/Linux) or the linux
(even if we do not recommend that) symbol versioning variant.
The former might be needed to circumvent compiler issues (i.e.
the compiler does not support all features that are required
for the linux versioning), the latter might help in overriding
the assumptions made in the configure script.

Jia Tan 82ecc53819 liblzma: Fix false Valgrind error report with GCC.
With GCC and a certain combination of flags, Valgrind will falsely
trigger an invalid write. This appears to be due to the omission of
instructions to properly save, set up, and restore the frame pointer.

The IFUNC resolver is a leaf function since it only calls a function
that is inlined. So sometimes GCC omits the frame pointer instructions
in the resolver unless this optimization is explictly disabled.

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=2267598.

Jia Tan 72d2933bfa liblzma: Use attribute no_profile_instrument_function with ifunc.
Thanks to Sam James for determining this was the attribute needed to
workaround the GCC bug and for his version of the patch in Gentoo.

Jia Tan e5faaebbcf Build: Require attribute no_profile_instrument_function for ifunc usage.
Using __attribute__((__no_profile_instrument_function__)) on the ifunc
resolver works around a bug in GCC -fprofile-generate:
it adds profiling code even to ifunc resolvers which can make
the ifunc resolver crash at program startup. This attribute
was not introduced until GCC 7 and Clang 13, so ifunc won't
be used with prior versions of these compilers.

This bug was brought to our attention by:


And was reported to upstream GCC by:

Jia Tan bbf112e323 xz: Change logging level for thread reduction to highest verbosity only.
Now that multi threaded encoding is the default, users do not need to
see a warning message everytime the number of threads is reduced. On
some machines, this could happen very often. It is not unreasonable for
users to need to set double verbose mode to see this kind of

To see these warning messages -vv or --verbose --verbose must be passed
to set xz into the highest possible verbosity mode.

These warnings had caused automated testing frameworks to fail when they
expected no output to stderr.

Thanks to Sebastian Andrzej Siewior for reporting this and for the
initial version of the patch.

Jia Tan 328c52da8a Build: Fix Linux Landlock feature test in Autotools and CMake builds.
The previous Linux Landlock feature test assumed that having the

Jia Tan 5d8d915ebe Bump version and soname for 5.7.0alpha.
Like 5.5.0alpha, 5.7.0alpha won't be released, it's just to mark that
the branch is not stable.

Once again there is no API/ABI stability for new features in devel
versions. The major soname won't be bumped even if API/ABI of new
features breaks between devel releases.

The French and Brazilian Portuguese man page translations have not been
updated since the switch from public domain to 0BSD. The old GPLv2

This will be fixed in the next round of translations, but this avoids
having a fuzzy match or not fixing the English version.

user_abort_pipe[] was still being used instead of the parameters.

Jia Tan 32b0a3ce19 Build: Fix ARM64 CRC32 instruction feature test.
Old versions of Clang reported the unsupported function attribute and
__crc32d() function as warnings instead of errors, so the feature test
passed when it shouldn't have, causing a compile error at build time.
-Werror was added to this feature test to fix this. The change is not
needed for CMake because check_c_source_compiles() also performs
linking and the error is caught then.

Thanks to Sebastian Andrzej Siewior for reporting this.

Lasse Collin de4337fd89 xz: Landlock: Fix error message if input file is a directory.
If xz is given a directory, it should look like this:

    $ xz /usr/bin
    xz: /usr/bin: Is a directory, skipping

The Landlock rules didn't allow opening directories for reading:

    $ xz /usr/bin
    xz: /usr/bin: Permission denied

The simplest fix was to allow opening directories for reading.
While it's a bit silly to allow it solely for the error message,
it shouldn't make the sandbox significantly weaker.

The single-file use case (like when called from GNU tar) is
still as strict as possible: all Landlock restrictions are
enabled before (de)compression starts.
