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 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 compiler the source code you need following software packages: - GCC compiler - GNU C library

Optional dependencies: - ZLIB library - LZMA library - ZSTD library - OPENSSL library (signature handling in modinfo)

Typical configuration: ./configure CFLAGS="-g -O2" --prefix=/usr
--sysconfdir=/etc --libdir=/usr/lib

Configure automatically searches for all required components and packages.

To compile and install run: make && make install

Hacking

Run 'autogen.sh' script before configure. If you want to accept the recommended flags, you just need to run 'autogen.sh c'.

Make sure to read the CODING-STYLE file and the other READMEs: libkmod/README and testsuite/README.

Compatibility with module-init-tools

kmod replaces module-init-tools, which is end-of-life. Most of its tools are rewritten on top of libkmod so it can be used as a drop in replacements. Somethings however were changed. Reasons vary from "the feature was already long deprecated on module-init-tools" to "it would be too much trouble to support it".

There are several features that are being added in kmod, but we don't keep track of them here.

modprobe

'modprobe -l' was marked as deprecated and does not exist anymore
'modprobe -t' is gone, together with 'modprobe -l'
modprobe doesn't parse configuration files with names not ending in '.alias' or '.conf'. modprobe used to warn about these files.
modprobe doesn't parse 'config' and 'include' commands in configuration files.
modprobe from m-i-t does not honour softdeps for install commands. E.g.: config:
```
  install bli "echo bli"
```
install bla "echo bla" softdep bla pre: bli

With m-i-t, the output of 'modprobe --show-depends bla' will be: install "echo bla"

While with kmod: install "echo bli" install "echo bla"
kmod doesn't dump the configuration as is in the config files. Instead it dumps the configuration as it was parsed. Therefore, comments and file names are not dumped, but on the good side we know what the exact configuration kmod is using. We did this because if we only want to know the entire content of configuration files, it's enough to use find(1) in modprobe.d directories

depmod

there's no 'depmod -m' option: legacy modules.*map files are gone

lsmod

module-init-tools used /proc/modules to parse module info. kmod uses /sys/module/*, but there's a fallback to /proc/modules if the latter isn't available

kmod's Issues

kmod 30 testsuite fails

kmod v30 testsuite fails on i586.

delta = 7

You're not initializing delta in test_backoff_time, and get_backoff_delta_msec then performs a read from uninitialized memory near !*delta.

Queried values not returned

kmov v.: 30

$ lsmod | grep -w ^tls
tls                   126976  0

Hello. Queried values are here returned. Nevertheless i am not competent to determine whether they are expected since i note that i am currently not in a script file.

# modinfo -l tls
Dual BSD/GPL
# modinfo -d tls
Transport Layer Security Support

This command still observes the previous semantic; which leads to expect that queried values are to be returned; as noticeable that is not the case.

# modinfo -d -l tls
Dual BSD/GPL

It might be the indication of an issue. Expected was

Excessive syscall usage, uncached data?

depmod (29) seems to do something out of the ordinary. This is with less than a handful of kernel modules.
Looks to me like it's re-reading the same data over and over again.
Unfortunately it leads to a very noticeable execution time using it during emulation due to the syscall heavy behavior.

$ strace -c depmod
% time seconds usecs/call calls errors syscall

When using multiple softdep for a module, only one of them have effects

Comments in the code suggest this might be intentional. But this is a surprising behavior. In addition to that, when there is already softdep commands in system's modules.softdep, user configured softdeps in /etc/modprobe.d will just be ignored, making it effectively non-user configurable. I think this is undesirable.

depmod: Allow output file location to be overridden

I've got a package build system that looks something like this:

stage dependencies into /
make / read-only (this is necessary not just to make sure we're not losing build output, but also due to the way build dependencies are stored in CAS)
stage sources into /work/dir, mark it writable. Create writeable /installdir
run build commands
everything inside of /installdir is the "output" of this package. Everything else gets discarded

I'd like to make a package that depends on the kernel & all the external modules I want, and runs depmod for this configuration. Then I can glue everything together at a later point (out of scope for this issue)

depmod isn't making this easy, because it always writes its output files into the kernel's directory. Since the kernel & modules are staged at /usr/lib/modules, and /usr/lib/modules is (necessarily) read-only, depmod will try and fail to write things into /usr/lib/modules/VERSION. I'd like a way to tell depmod to actually write into /installdir/usr/lib/modules/VERSION, or somewhere inside of /work/dir so that I could then manually install the files into the right place.

For now, we've got a workaround that looks something like this:

link /usr/lib/modules/VERSION/kernel into /installdir/usr/lib/modules/VERSION/kernel
Copy /usr/lib/modules/VERSION/modules.order into /installdir/usr/lib/modules/VERSION/modules.order
Same with modules.builtin
Run depmod -a -b /installdir/usr VERSION
Delete /installdir/usr/lib/modules/VERSION/{kernel,modules.order,modules.builtin}
The files created by depmod remain in /installdir/usr/lib/modules/VERSION, as we'd like

Potential solutions for depmod:

depmod could respect an environment variable like DESTDIR or similar (like in autotools: for example in my use-case above DESTDIR=/installdir)
depmod could add a command line flag that plays a role similar to the DESTDIR env var
depmod could add a command line flag to just dump the files into the current working directory. From there they could manually be installed into wherever they need to go

This is a "golden image" use-case. There is no way depmod could run from userspace like it does in most other distros

Error:make

tools/kmod.c:173:12: error: use of undeclared identifier 'program_invocation_short_name'
if (streq(program_invocation_short_name, "kmod"))

depmod updates modules.* files even when not needed

Seems like depmod will eagerly overwrite many of the existing modules.* files, even if there are no changes vs the existing files.
Can we fix the tool to write the files, only as needed?

Thanks in advance

Simple reproducer:

#!/bin/bash

echo "1. Fetch checksums - file timestamps and contents"
mkdir before
for i in /usr/lib/modules/$(uname -r)/modules.*; do
  mname=$(basename $i)
  ls -la $i | sha256sum > before/$mname-ls.sum
  sha256sum $i > before/$mname.sum
done

echo "2. Kick off depmod"
depmod $(uname -r)

echo "3. Re-fetch checksums - file timestamps and contents"
mkdir after
for i in /usr/lib/modules/$(uname -r)/modules.*; do
  mname=$(basename $i)
  ls -la $i | sha256sum > after/$mname-ls.sum
  sha256sum $i > after/$mname.sum
done

echo "4. Compare - observe how most module.* timestamps have changed, yet contents are identical"
$ diff -rq before after

The changes ->
Files before/modules.alias.bin-ls.sum and after/modules.alias.bin-ls.sum differ
Files before/modules.alias-ls.sum and after/modules.alias-ls.sum differ
Files before/modules.builtin.alias.bin-ls.sum and after/modules.builtin.alias.bin-ls.sum differ
Files before/modules.builtin.bin-ls.sum and after/modules.builtin.bin-ls.sum differ

Files before/modules.devname-ls.sum and after/modules.devname-ls.sum differ
Files before/modules.softdep-ls.sum and after/modules.softdep-ls.sum differ
Files before/modules.symbols.bin-ls.sum and after/modules.symbols.bin-ls.sum differ

kmod-29

Worked fine.. until this
https://git.kernel.org/pub/scm/utils/kernel/kmod/kmod.git/commit/?id=82972710196442c503cc1068a05651c354a865fb
and.. that is happening on latest commit too ( https://git.kernel.org/pub/scm/utils/kernel/kmod/kmod.git/commit/?id=94f7683c5a5084b61756c6df29c14041efebcd94 )
The problem: doing modprobe or modinfo on unexisting module throws kmod into a segfault..
modinfo blahblah
Segmentation fault
Any ideea ?

New release?🤔

v30...master shows +30 commits since last release which was more than year ago.
Do you have any plans to release new version soon? 🤔

May I know, how to avoid the warning?

modprobe fails w/ error if module is built into the kernel

Let's try out this new official github!

I'm running kmod 28 on my own in-dev distro. modprobe will now fail and report that it could not find a module if you try to load a module that is built-into the kernel. I ran into this w/ dracut in my initramfs:

Dracut runs modprobe overlay to load the overlayfs module, which is built-in. In kmod 27, modprobe exits silently w/ an exit code of 0. In kmod 28, modprobe prints an error about how it couldn't find the module in /lib/modules/5.10.19, then exits with a code of 1. Dracut picks this up, assumes that it cannot properly mount the rootfs because of the missing module, and refuses to boot.

Is this an intentional change or a bug?

testsuite failures on mipsel

The latest upload of kmod in Debian enabled the testsuite to be run during build. This caused the testsuite to fail on mipsel.

lsmod: fallback to procfs

On Linux 5.15.12, kmod-29, inside an nspawn container, I observe, somewhat expectedly:

$ lsmod 2>&1 | grep twofish_comm
libkmod: kmod_module_get_holders: could not open '/sys/module/twofish_common/holders': No such file or directory
twofish_common            -2  -2

Since /proc/modules is already opened by libkmod to discover the list of loaded modules, wouldn't it be possible to also source the other information from there as a fallback?

$ grep twofish_com /proc/modules
twofish_common 24576 4 twofish_generic,twofish_avx_x86_64,twofish_x86_64_3way,twofish_x86_64, Live 0x0000000000000000 (E)

Segmentation fault when running depmod/kmod

Hi :)

I first reported the bug here: https://bugs.archlinux.org/task/77868 but since it is an upstream issue, I want to report it here as well.

I built a custom Linux kernel with debugging information. If I'm correct the bug occurs when keeping the debug information in the modules. Excerpt from the PKGBUILD file (Arch Linux):

  echo "Installing modules..."
  make INSTALL_MOD_PATH="$pkgdir/usr" INSTALL_MOD_STRIP="--only-keep-debug" \
    DEPMOD=/doesnt/exist modules_install  # Suppress depmod

INSTALL_MOD_STRIP="--only-keep-debug" was INSTALL_MOD_STRIP=1 before the modification.

While running sudo pacman -U linux-dbg-6.2.6.arch1-1-x86_64.pkg.tar.zst and with

gdb -ex "set disassembly-flavor intel" -ex "run" -ex "bt full" -ex "info registers" -ex 'x/50i $pc' -ex 'x/50gx $sp' -args depmod -b "$BUILDROOT" "$KERNELVERSION"

I could upload the linux-dbg-6.2.6.arch1-1-x86_64.pkg.tar.zst package somewhere if necessary.

depmod: built-in module is updated into modules.dep instead of the duplicated one in "extra" dir

Hello,

As we know, module in "extra" has higher priority than the duplicate one in kernel.

But it looks like when we run depmod, inside it, the readdir() read sub-dirs of /lib/modules/5.18.0-0.bpo.1-rt-amd64/, it does not always read out "extra" before "kernel" and this makes ko path in built-in kernel is updated into modules.dep, but what we want is the path in "extra".

I was using isar: https://github.com/ilbers/isar to build a system img
and in the img, i have one ko as kernel built-in and a duplicated one in "extra"
before start the img, i chroot into the rootfs of the img on the build machine, but when I run "depmod -a $(ls /lib/modules/)", it will put built-in ko into modules.dep and I found readdir read kernel dir firstly instead of extra dir.

kernel is read firstly by readdir():

module in extra is set as lower prio:

usb:btusb's problem

I have a question for kmod.
There is a soft connection file usb:btusb existing in kmod/testsuite/rootfs-pristine/test-loaded/sys/module/btusb, Who’s link object of the file is empty.
The testsuite file does not affect the main functions. But I want to make sure whether it is a problem.

Thanks!
