kmod 5
======
- Break libkmod's API to insert a module like modprobe does. It now accepts
extra an extra argument to print its action and acceptable flags were
sanitized.
- Share more code between modprobe and libkmod: using the new version of
kmod_module_probe_insert_module() it's possible to share a great amount of
code between modprobe and libkmod
- modprobe no longer works with paths: it only accepts module names and/or
aliases now.
- testsuite was added to repository, allowing automated tests to be run and
easing the way bugs are reproduced.
- modprobe: when dumping configuration ('-c' option) separate config
and indexes by adding a commented line between them.
- Fix bugs wrt normalizing aliases and module names
- Fix bug wrt inserting an alias that resolves to multiple modules: we should
not stop on the first error, but rather continue to try loading other
modules.
- Fix unaligned memory access in hash function, causing depmod to output wrong
information in ARMv5
- Fix man page build and install: now they are only installed if tools are
enabled
kmod 4
======
- New APIs in libkmod to:
- Get configuration lists: blacklists, install commands, remove
commands, aliases, options and softdeps
- Dump indexes
- Several bugs fixed in libkmod, modprobe, depmod and modinfo
- API documentation: if configure with run with --enable-gtk-doc, the API doc
will be generated by make. Gtk-doc is required for that.
- Man pages are built, which replace man pages from module-init-tools
- 'include' and 'config' options in *.conf files were deprecated
- configure is not run by autogen.sh. Instead, a common set of options is
printed. If you are hacking on kmod, consider using bootstrap-configure
script.
- 'modprobe -c' works as expected now. As opposed to module-init-tools, it
dumps the parsed configuration, not only the file contents.
kmod 3
======
- New APIs in libkmod to:
- Get symbols from module, parsing the ELF section
- Get dependency symbols
- Check if resources are still valid or if libkmod must be reloaded
- Insert module like modprobe, checking (soft-)dependencies, commands,
blacklist. It can run commands by itself and to call a callback
function.
- Support to load modules compressed with xz
- Tools are now bundled together in a single tool called kmod. It can be
called using symlinks with the same names as tools from module-init-tools.
E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
1:1 replacement of module-init-tools.
- The only missing tool, depmod, was added to kmod together with the necessary
APIs in libkmod.
- If a program using libkmod runs for a long time, as for example udev, it must
check if it doesn't have to re-load libkmod. A new helper function was added
in libkmod to check if context is still valid and udev is already using it.
- An 'unaligned access' bug was fixed. So those architecture that does not
handle unaligned access can use kmod, too.
kmod 2
======
Some bugs fixed: the worst of them was with an infinite loop when an alias
matched more than one module.
- New APIs in libkmod to:
- Get soft dependencies
- Get info from module files parsing ELF
- Get modversions from files parsing ELF
- Support to load gzipped kernel modules: kmod can be compiled with support to
gzipped modules by giving the --enable-zlib flag
- Support to forcefully load modules, both vermagic and modversion
- Support to force and nowait removal flags
- Configuration files are parsed in the same order as modprobe: files are
sorted alphabetically (independently of their dir) and files with the same
name obey a precedence order
- New tool: kmod-modinfo
- kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
The only missing things are the options '--showconfig' and '-t / -l'. These
last ones have been deprecated long ago and they will be removed from
modprobe. A lot of effort has been put on kmod-modprobe to ensure it
maintains compabitility with modprobe.
- linux-modules@vger.kernel.org became the official mailing list for kmod
kmod 1
======
First version of kmod and its library, libkmod.
In the libkmod it's currently possible to:
- List modules currently loaded
- Get information about loaded modules such as initstate, refcount,
holders, sections, address and size
- Lookup modules by alias, module name or path
- Insert modules: options from configuration and extra options can be
passed, but flags are not implemented, yet
- Remove modules
- Filter list of modules using blacklist
- For each module, get the its list of options and install/remove
commands
- Indexes can be loaded on startup to speedup lookups later
Tools provided with the same set of options as in module-init-tools:
- kmod-lsmod
- kmod-insmod
- kmod-rmmod
- kmod-modprobe, with some functionality still missing (use of softdep,
dump configuration, show modversions)
