kmod - Linux kernel module handling
OVERVIEW
kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.
These tools are designed on top of libkmod, a library that is shipped with kmod. See libkmod/README.md for more details on this library and how to use it. The aim is to be compatible with tools, configurations and indexes from module-init-tools project.

Compilation and installation
In order to compile the source code you need:
- C11 compiler, supporting a range of GNU extensions - GCC 8+, Clang 6+
- POSIX.1-2008 C runtime library - Bionic, GNU C library, musl
Optional dependencies, required with the default build configuration:
- ZLIB library
- LZMA library
- ZSTD library
- OPENSSL library (signature handling in modinfo)
Typical configuration and installation
meson setup builddir/
meson compile -C builddir/
sudo meson install -C builddir/
For end-user and distributions builds, it's recommended to use:
meson setup --buildtype release builddir/
Hacking
When working on kmod, use the included build-dev.ini file, as:
meson setup --native-file build-dev.ini builddir/
The testsuite can be executed with:
meson test -C builddir
It builds test kernel modules, so kernel headers need to be pre-installed. By
default it tries to use the kernel header for the currently running kernel.
KDIR=any environment variable can be used to tell it to use any installed
kernel header or KDIR=/path/to/specific/headers when a specific one is
needed. Example:
KDIR=any meson test -C builddir
Make sure to read our contributing guide and the other READMEs: libkmod and testsuite.
Compatibility with module-init-tools
kmod replaced module-init-tools, which was EOL'ed in 2011. All the tools were rewritten on top of libkmod and they can be used as drop in replacements. Along the years there were a few behavior changes and new features implemented, following feedback from Linux kernel community and distros.
