- Improvements
- Allow to handle compressed modules even without decompression
libraries linked in. Previously we would detect if the kernel
supported the decompression algorithm and pass the module directly
through finit_module(). However it wouldn't consider the file if
the respective decompression library was compiled out. Now it's
possible to completely disable all libraries and still have module
load working with libkmod.
Tools that inspect module content themselves like modinfo and depmod
won't work if the decompression library is not enabled.
- Add weak dependencies - these are similar to pre softdep, but they
don't cause the dependency to be loaded by libkmod: when a module has
a weak dependency, it is expected that module may or may not be used,
with decision happening in runtime by the kernel. It's purpose is to
be informational for other tools like ones used to create initramfs,
so the module is made available before switch_root(), but doesn't
imply it to be loaded when not needed.
- Improve compatibility with non-gnu libc like musl and uClibc. Now it's
possible to build and use libkmod and tools without any additional compat
patches.
- Move manpages from xsltproc to scdoc, which is now needed during build.
- Improve documentation in manpages, fixing typos, rewording sentences,
detailing how configuration files are handled with precedence order
and making all the manpages more consistent on how to reference options,
environment variables, configuration, authors, etc.
- Speed up zstd decompression, particularly when not using glibc.
- Stop parsing .alias files from modprobe.d directories. Configuration files
were always documented as needing the .conf extension. For compatibility
reason with module-init-tools, kmod also parsed .alias files. However that
was also done in module-init-tools for compatibility reasons and not
documented anywhere. From inspection on what distros are using, none use
.alias files in practice, so stop parsing those files and follow what's
documented.
- Adopt SPDX for license and cleanup comments on individual files.
- Since kmod 29 there's a github mirror for the repository. Now it's
also used for issues and improvement tracking. With that, the old
TODO file has been removed and distros/users are encouraged to file
issues in github.
- Bug fixes
- Move kmod.pc to the right dir, ${datadir}/pkgconfig, as it's related
to kmod, not libkmod.
- Fix error handling while loading a file and mmap fails.
- Fix error handling while handling errors from the decompression
libraries.
- Add missing documentation for KMOD_INDEX_MODULES_BUILTIN that was
added in v27 breaking the ABI. A wide search has found one external
tool using it, which hasn't been updated in the past 12 years. It
was deemed safe to simply update the documentation to include the
missing enum.
- Move kmod_module_new_from_name_lookup() to the correct symbol
version. It was added by mistake to @LIBKMOD_5 when v30 got released.
No external user of this API was found, so it was considered safe
to just move it.
- Fix undefined behavior while parsing builtins
- Others
- Overwrite symlinks when installing tools.
- General cleanup of how (de)compression libraries are integrated.
- Add CI infrastructure to automatically test in several distros
before applying commit series. Currently the latest versions of
Alpine, Archlinux, Fedora and Ubuntu are covered. More distros are
easy to add as they are all containerized.
