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
