According to the source tarball's NEWS file:
- Improvements
- Allow passing a path to modprobe so the module is loaded from
anywhere from the filesystem, but still handling the module
dependencies recorded in the indexes. This is mostly intended for kernel
developers to speedup testing their kernel modules without having to load the
dependencies manually or override the module in /usr/lib/modules/.
Now it's possible to do:
# modprobe ./drivers/gpu/drm/i915/i915.ko
As long as the dependencies didn't change, this should do the right thing
- Use in-kernel decompression if available. This will check the runtime support
in the kernel for decompressing modules and use it through finit_module().
Previously kmod would fallback to the older init_module() when using
compressed modules since there wasn't a way to instruct the kernel to
uncompress it on load or check if the kernel supported it or not.
This requires a recent kernel (>= 6.4) to have that support and
in-kernel decompression properly working in the kernel.
- Make modprobe fallback to syslog when stderr is not available, as was
documented in the man page, but not implemented
- Better explaing `modprobe -r` and how it differentiates from rmmod
- depmod learned a `-o <dir>` option to allow using a separate output
directory. With this, it's possible to split the output files from
the ones used as input from the kernel build system
- Add compat with glibc >= 2.32.9000 that dropped __xstat
- Improve testsuite to stop skipping tests when sysconfdir is something
other than /etc
- Build system improvements and updates
- Change a few return codes from -ENOENT to -ENODATA to avoid confusing output
in depmod when the module itself lacks a particular ELF section due to e.g.
CONFIG_MODVERSIONS=n in the kernel.
- Bug Fixes
- Fix testsuite using uninitialized memory when testing module removal
with --wait
- Fix testsuite not correctly overriding the stat syscall on 32-bit
platforms. For most architectures this was harmless, but for MIPS it
was causing some tests to fail.
- Fix handling unknown signature algorithm
- Fix linking with a static liblzma, libzstd or zlib
- Fix memory leak when removing module holders
- Fix out-of-bounds access when using very long paths as argument to rmmod
- Fix warnings reported by UBSan

kmod 29
=======
- Improvements
- Add support to use /usr/local as a place for configuration files. This makes it easier
to install locally without overriding distro files.
- Bug fixes
- Fix `modinfo -F` when module is builtin: when we asked by a specific field from modinfo,
it was not working correctly if the module was builtin
- Documentation fixes on precedence order of /etc and /run: the correct order is
/etc/modprobe.d, /run/modprobe.d, /lib/modprobe.d
- Fix the priority order that we use for searching configuration files. The
correct one is /etc, /run, /usr/local/lib, /lib, for both modprobe.d
and depmo.d
- Fix kernel command line parsing when there are quotes present. Grub
mangles the command line and changes it from 'module.option="val with
spaces"' to '"module.option=val with spaces"'. Although this is weird
behavior and grub could have been fixed, the kernel understands it
correctly for builtin modules. So change libkmod to also parse it
correctly. This also brings another hidden behavior from the kernel:
newline in the kernel command line is also allowed and can be used to
separate options.
- Fix a memory leak, overflow and double free on error path
- Fix documentation for return value from kmod_module_get_info(): we
return the number of entries we added to the list
- Fix output of modules.builtin.alias.bin index: we were writing an empty file due to
the misuse of kmod_module_get_info()
- Infra/internal
- Retire integration with semaphoreci
- Declare the github mirror also as an official upstream source: now besides accepting
patches via mailing list, PRs on github are also acceptable
- Misc improvements to testsuite, so we can use it reliably regardless
of the configuration used: now tests will skip if we don't have the
build dependencies)

This patch links kmod against OpenSSL which is required to
decode the kernel modules' PKCS#7 signatures.
