   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 * create test-mock library to be LD_PRELOAD'ed before running the binaries
  12   so we're able to create unit tests
  13
  14 * review API, maybe unify all of these setters:
  15    - kmod_module_version_get_symbol()
  16    - kmod_module_version_get_crc()
  17    - kmod_module_symbol_get_symbol()
  18    - kmod_module_symbol_get_crc()
  19    - kmod_module_dependency_symbol_get_symbol()
  20    - kmod_module_dependency_symbol_get_crc()
  21    - kmod_module_versions_free_list()
  22    - kmod_module_symbols_free_list()
  23    - kmod_module_dependency_symbols_free_list()
  24
  25 * unify code from modprobe and libkmod:
  26    - remove kmod_module_probe_insert() and turn it into
  27      kmod_module_probe_get_list(); this way modprobe can use it too
  28
  29 * provide modules.archive, a cache file with all modules compressed
  30   and a fast access. It's like a tar.gz, but with each entry
  31   compressed as opposed to the whole tar compressed, easy to pick
  32   individual entries, that is, more like .gz.tar. As zlib compression
  33   does not store the uncompressed file size, this could provide
  34   it. The file format should be something like:
  35      MAGIC-ID
  36      DIRECTORY-ENTRY-SIZE
  37      DIRECTORY (hash-like format, points to file offset and size)
  38      ENTRIES (each is a compressed module)
  39   Helper binary to:
  40      kmod-archive list
  41      kmod-archive add path.ko
  42      kmod-archive rm path.ko
  43      kmod-archive get path.ko
  44      kmod-archive exists path.ko
  45
  46 * Stop using system() inside the library and use fork + exec instead

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