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