   1 Features:
   2 =========
   3
   4 * config: configs that do not need to be matched by fnmatch() could be using a
   5   vector instead of a list. This way we could search in it by calling
   6   bsearch().
   7
   8 * index: drop the "open(), seek(), read()" implementation and use another one
   9   with mmap(). When lookup() is called and the file is not mmaped, mmap it.
  10
  11 * review API, maybe unify all of these setters:
  12    - kmod_module_version_get_symbol()
  13    - kmod_module_version_get_crc()
  14    - kmod_module_symbol_get_symbol()
  15    - kmod_module_symbol_get_crc()
  16    - kmod_module_dependency_symbol_get_symbol()
  17    - kmod_module_dependency_symbol_get_crc()
  18    - kmod_module_versions_free_list()
  19    - kmod_module_symbols_free_list()
  20    - kmod_module_dependency_symbols_free_list()
  21
  22 * unify code from modprobe and libkmod:
  23    - remove kmod_module_probe_insert() and turn it into
  24      kmod_module_probe_get_list(); this way modprobe can use it too
  25
  26 * provide modules.archive, a cache file with all modules compressed
  27   and a fast access. It's like a tar.gz, but with each entry
  28   compressed as opposed to the whole tar compressed, easy to pick
  29   individual entries, that is, more like .gz.tar. As zlib compression
  30   does not store the uncompressed file size, this could provide
  31   it. The file format should be something like:
  32      MAGIC-ID
  33      DIRECTORY-ENTRY-SIZE
  34      DIRECTORY (hash-like format, points to file offset and size)
  35      ENTRIES (each is a compressed module)
  36   Helper binary to:
  37      kmod-archive list
  38      kmod-archive add path.ko
  39      kmod-archive rm path.ko
  40      kmod-archive get path.ko
  41      kmod-archive exists path.ko
  42
  43 * Stop using system() inside the library and use fork + exec instead
  44
  45 Known Bugs:
  46 ===========
  47
  48
  49 Things to be added/removed in kernel (check what is really needed):
  50 ===================================================================
  51
  52 * list of currently loaded modules
  53         - readdir() in /sys/modules: dirs without a 'initstate' file mean the
  54           modules is builtin.
  55
  56 * module's size should be available under /sys
  57         - DONE in 3.3: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
  58
  59 * kill /proc/modules ?
  60         - Unlikely, given other tools might depend on it
  61
  62 Things that are different from module-init-tools on purpose (!TODO)
  63 ===================================================================
  64
  65 modprobe
  66 --------
  67
  68 * 'modprobe -l' was marked as deprecated and does not exist anymore
  69
  70 * 'modprobe -t' is gone, together with 'modprobe -l'
  71
  72 * there's and additional '--remove-dependencies' flags to kmod-modprobe so we
  73   can remove modules depending on that one
  74
  75 * kmod-modprobe doesn't parse configuration files whose name don't end on
  76   '.alias'  or '.conf'. modprobe used to warn about these files.
  77
  78 * kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
  79   files.
  80
  81 * we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
  82   module appearing on /sys/modules/* without a initstate file to determine if
  83   it is builtin.
  84
  85 * modprobe from m-i-t does not honour softdeps for install commands. E.g.:
  86   config:
  87
  88         install bli "echo bli"
  89         install bla "echo bla"
  90         softdep bla pre: bli
  91
  92   With m-i-t, the output of 'modprobe --show-depends bla' will be:
  93         install "echo bla"
  94
  95   While with kmod:
  96         install "echo bli"
  97         install "echo bla"
  98
  99 * kmod doesn't dump the configuration as is in the config files. Instead it
 100   dumps the configuration as it was parsed. Therefore, comments and file names
 101   are not dumped, but on the good side we know what the exact configuration
 102   kmod is using. We did this because if we only want to know the entire content
 103   of configuration files, it's enough to use find(1) in modprobe.d directories
 104
 105 depmod
 106 ------
 107
 108 * there's no 'depmod -m' option: legacy modules.*map files are gone
 109
 110 lsmod
 111 -----
 112
 113 * information is parsed from /sys instead of /proc/modules
