   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 * Add functions to dump configuration. Create a list with the config items
  15   (blacklist, aliases, etc) or just dump to a fd?
  16
  17 * Add functions to list all modules known by modules.dep
  18
  19 * provide 1:1 compatibility with module-init-tools's modprobe
  20    - dump configuration
  21    - deal with dependency loop
  22    - fix dependency listing in --show-depends
  23         $ modprobe -S 3.2.0-2-ARCH --show-depends ahci
  24         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz
  25         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz
  26         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/ata/libata.ko.gz
  27         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz
  28         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz
  29         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/ata/libata.ko.gz
  30         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/ata/libahci.ko.gz
  31         insmod /lib/modules/3.2.0-2-ARCH/kernel/drivers/ata/ahci.ko.gz
  32
  33 * Add manpages: copy them from module-init-tools and make the necessary changes
  34
  35 * review API, maybe unify all of these setters:
  36    - kmod_module_version_get_symbol()
  37    - kmod_module_version_get_crc()
  38    - kmod_module_symbol_get_symbol()
  39    - kmod_module_symbol_get_crc()
  40    - kmod_module_dependency_symbol_get_symbol()
  41    - kmod_module_dependency_symbol_get_crc()
  42    - kmod_module_versions_free_list()
  43    - kmod_module_symbols_free_list()
  44    - kmod_module_dependency_symbols_free_list()
  45
  46 * provide modules.archive, a cache file with all modules compressed
  47   and a fast access. It's like a tar.gz, but with each entry
  48   compressed as opposed to the whole tar compressed, easy to pick
  49   individual entries, that is, more like .gz.tar. As zlib compression
  50   does not store the uncompressed file size, this could provide
  51   it. The file format should be something like:
  52      MAGIC-ID
  53      DIRECTORY-ENTRY-SIZE
  54      DIRECTORY (hash-like format, points to file offset and size)
  55      ENTRIES (each is a compressed module)
  56   Helper binary to:
  57      kmod-archive list
  58      kmod-archive add path.ko
  59      kmod-archive rm path.ko
  60      kmod-archive get path.ko
  61      kmod-archive exists path.ko

  63 Known Bugs:
  64 ===========
  65
  66
  67 Things to be added/removed in kernel (check what is really needed):
  68 ===================================================================
  69
  70 * list of currently loaded modules
  71
  72 * module's size should be available under /sys
  73
  74 * kill /proc/modules ?
  75
  76 Things that are different from module-init-tools on purpose (!TODO)
  77 ===================================================================
  78
  79 modprobe
  80 --------
  81
  82 * 'modprobe -l' was marked as deprecated and does not exist anymore
  83
  84 * 'modprobe -t' is gone, together with 'modprobe -l'
  85
  86 * there's and additional '--remove-dependencies' flags to kmod-modprobe so we
  87   can remove modules depending on that one
  88
  89 * kmod-modprobe doesn't parse configuration files whose name don't end on
  90   '.alias'  or '.conf'. modprobe used to warn about these files.
  91
  92 * kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
  93   files.
  94
  95 * we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
  96   module appearing on /sys/modules/* without a initstate file to determine if
  97   it is builtin.
  98
  99 * modprobe from m-i-t does not honour softdeps for install commands. E.g.:
 100   config:
 101
 102         install bli "echo bli"
 103         install bla "echo bla"
 104         softdep bla pre: bli
 105
 106   With m-i-t, the output of 'modprobe --show-depends bla' will be:
 107         install "echo bla"
 108
 109   While with kmod:
 110         install "echo bli"
 111         install "echo bla"
 112
 113 depmod
 114 ------
 115
 116 * there's no 'depmod -m' option: legacy modules.*map files are gone
