* config: configs that do not need to be matched by fnmatch() could be using a
vector instead of a list. This way we could search in it by calling
* index: drop the "open(), seek(), read()" implementation and use another one
with mmap(). When lookup() is called and the file is not mmaped, mmap it.
* review API, maybe unify all of these setters:
- kmod_module_version_get_symbol()
- kmod_module_version_get_crc()
- kmod_module_symbol_get_symbol()
- kmod_module_symbol_get_crc()
- kmod_module_dependency_symbol_get_symbol()
- kmod_module_dependency_symbol_get_crc()
- kmod_module_versions_free_list()
- kmod_module_symbols_free_list()
- kmod_module_dependency_symbols_free_list()
* provide modules.archive, a cache file with all modules compressed
and a fast access. It's like a tar.gz, but with each entry
compressed as opposed to the whole tar compressed, easy to pick
individual entries, that is, more like .gz.tar. As zlib compression
does not store the uncompressed file size, this could provide
it. The file format should be something like:
DIRECTORY (hash-like format, points to file offset and size)
ENTRIES (each is a compressed module)
Helper binary to:
kmod-archive list
kmod-archive add path.ko
kmod-archive rm path.ko
kmod-archive get path.ko
kmod-archive exists path.ko
* Stop using system() inside the library and use fork + exec instead
Known Bugs:
Things to be added/removed in kernel (check what is really needed):
* list of currently loaded modules
- readdir() in /sys/modules: dirs without a 'initstate' file mean the
modules is builtin.
* module's size should be available under /sys
- DONE in 3.3:;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
* kill /proc/modules ?
- Unlikely, given other tools might depend on it
Things that are different from module-init-tools on purpose (!TODO)
* 'modprobe -l' was marked as deprecated and does not exist anymore
* 'modprobe -t' is gone, together with 'modprobe -l'
* there's and additional '--remove-dependencies' flags to kmod-modprobe so we
can remove modules depending on that one
* kmod-modprobe doesn't parse configuration files whose name don't end on
'.alias' or '.conf'. modprobe used to warn about these files.
* kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
* we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
module appearing on /sys/modules/* without a initstate file to determine if
it is builtin.
* modprobe from m-i-t does not honour softdeps for install commands. E.g.:
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
* there's no 'depmod -m' option: legacy modules.*map files are gone
* information is parsed from /sys instead of /proc/modules
