   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
  40
  41 * testsuite:
  42    - when fake init_module() succeeds, create an entry in /sys/module
  43    - when fake delete_module() succeeds, remove its entry from /sys/module
  44    - add test for dependency loop _with install commands_ relying on module
  45      already been loaded in order to succeed. E.g.:
  46          install vboxdrv modprobe -i vboxdrv; modprobe -i vboxnetflt
  47    - check if vboxdrv bug is the same of alsa package in Debian
  48
  49 * add quirk so we don't calculate dependencies for modules already loaded -
  50   that shall fix the bug of vboxdrv and alsa above
  51
  52 * search /lib/modules/$(uname -r)/modules.builtin.bin before returning error
  53   that module was not found
  54
  55 Known Bugs:
  56 ===========
  57
  58
  59 Things to be added/removed in kernel (check what is really needed):
  60 ===================================================================
  61
  62 * list of currently loaded modules
  63         - readdir() in /sys/modules: dirs without a 'initstate' file mean the
  64           modules is builtin.
  65
  66 * module's size should be available under /sys
  67         - DONE in 3.3: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
  68
  69 * kill /proc/modules ?
  70         - Unlikely, given other tools might depend on it
  71
  72 Things that are different from module-init-tools on purpose (!TODO)
  73 ===================================================================
  74
  75 modprobe
  76 --------
  77
  78 * 'modprobe -l' was marked as deprecated and does not exist anymore
  79
  80 * 'modprobe -t' is gone, together with 'modprobe -l'
  81
  82 * there's and additional '--remove-dependencies' flags to kmod-modprobe so we
  83   can remove modules depending on that one
  84
  85 * kmod-modprobe doesn't parse configuration files whose name don't end on
  86   '.alias'  or '.conf'. modprobe used to warn about these files.
  87
  88 * kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
  89   files.
  90
  91 * we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
  92   module appearing on /sys/modules/* without a initstate file to determine if
  93   it is builtin.
  94
  95 * modprobe from m-i-t does not honour softdeps for install commands. E.g.:
  96   config:
  97
  98         install bli "echo bli"
  99         install bla "echo bla"
 100         softdep bla pre: bli
 101
 102   With m-i-t, the output of 'modprobe --show-depends bla' will be:
 103         install "echo bla"
 104
 105   While with kmod:
 106         install "echo bli"
 107         install "echo bla"
 108
 109 * kmod doesn't dump the configuration as is in the config files. Instead it
 110   dumps the configuration as it was parsed. Therefore, comments and file names
 111   are not dumped, but on the good side we know what the exact configuration
 112   kmod is using. We did this because if we only want to know the entire content
 113   of configuration files, it's enough to use find(1) in modprobe.d directories
 114
 115 depmod
 116 ------
 117
 118 * there's no 'depmod -m' option: legacy modules.*map files are gone
 119
 120 lsmod
 121 -----
 122
 123 * information is parsed from /sys instead of /proc/modules
