Fabrice Fontaine 3d1bd339ab configure.ac: fix link with -llzma 
Add liblzma_LIBS to LIBS to avoid the following build failure when
building with a static-only liblzma.a:

/home/autobuild/autobuild/instance-5/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/11.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: libkmod/.libs/libkmod-internal.a(libkmod-file.o):(.text.xz_uncompress+0x10): undefined reference to `lzma_code'

For consistency, also update libzstd, zlib and libcrypto

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'. Note that the recommended flags require cython be installed to compile successfully.

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
