   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 * provide modules.archive, a cache file with all modules compressed
  23   and a fast access. It's like a tar.gz, but with each entry
  24   compressed as opposed to the whole tar compressed, easy to pick
  25   individual entries, that is, more like .gz.tar. As zlib compression
  26   does not store the uncompressed file size, this could provide
  27   it. The file format should be something like:
  28      MAGIC-ID
  29      DIRECTORY-ENTRY-SIZE
  30      DIRECTORY (hash-like format, points to file offset and size)
  31      ENTRIES (each is a compressed module)
  32   Helper binary to:
  33      kmod-archive list
  34      kmod-archive add path.ko
  35      kmod-archive rm path.ko
  36      kmod-archive get path.ko
  37      kmod-archive exists path.ko
  38
  39 * Stop using system() inside the library and use fork + exec instead

  41 Known Bugs:
  42 ===========
  43
  44
  45 Things to be added/removed in kernel (check what is really needed):
  46 ===================================================================
  47
  48 * list of currently loaded modules
  49         - readdir() in /sys/modules: dirs without a 'initstate' file mean the
  50           modules is builtin.
  51
  52 * module's size should be available under /sys
  53         - DONE in 3.3: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
  54
  55 * kill /proc/modules ?
  56         - Unlikely, given other tools might depend on it
  57
  58 Things that are different from module-init-tools on purpose (!TODO)
  59 ===================================================================
  60
  61 modprobe
  62 --------
  63
  64 * 'modprobe -l' was marked as deprecated and does not exist anymore
  65
  66 * 'modprobe -t' is gone, together with 'modprobe -l'
  67
  68 * there's and additional '--remove-dependencies' flags to kmod-modprobe so we
  69   can remove modules depending on that one
  70
  71 * kmod-modprobe doesn't parse configuration files whose name don't end on
  72   '.alias'  or '.conf'. modprobe used to warn about these files.
  73
  74 * kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
  75   files.
  76
  77 * we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
  78   module appearing on /sys/modules/* without a initstate file to determine if
  79   it is builtin.
  80
  81 * modprobe from m-i-t does not honour softdeps for install commands. E.g.:
  82   config:
  83
  84         install bli "echo bli"
  85         install bla "echo bla"
  86         softdep bla pre: bli
  87
  88   With m-i-t, the output of 'modprobe --show-depends bla' will be:
  89         install "echo bla"
  90
  91   While with kmod:
  92         install "echo bli"
  93         install "echo bla"
  94
  95 * kmod doesn't dump the configuration as is in the config files. Instead it
  96   dumps the configuration as it was parsed. Therefore, comments and file names
  97   are not dumped, but on the good side we know what the exact configuration
  98   kmod is using. We did this because if we only want to know the entire content
  99   of configuration files, it's enough to use find(1) in modprobe.d directories
 100
 101 depmod
 102 ------
 103
 104 * there's no 'depmod -m' option: legacy modules.*map files are gone
 105
 106 lsmod
 107 -----
 108
 109 * information is parsed from /sys instead of /proc/modules
