   1 Features:
   2 =========
   3
   4 * testsuite:
   5    - when fake delete_module() succeeds, remove its entry from /sys/module
   6
   7 * review API, maybe unify all of these getters:
   8    - kmod_module_version_get_symbol()
   9    - kmod_module_version_get_crc()
  10    - kmod_module_symbol_get_symbol()
  11    - kmod_module_symbol_get_crc()
  12    - kmod_module_dependency_symbol_get_symbol()
  13    - kmod_module_dependency_symbol_get_crc()
  14    - kmod_module_versions_free_list()
  15    - kmod_module_symbols_free_list()
  16    - kmod_module_dependency_symbols_free_list(
  17
  18    Main reason for this is that they need to open and read the module to get
  19    this information. If module is compressed, that means uncompressing +
  20    allocating necessary space + deallocating for each of them. depmod uses most
  21    of these functions and in the end it uncompresses the module ~6x times more
  22    than needed, which makes depmod very slow if compared to module-init-tools.
  23
  24    We might want to either cache the elf file within kmod_module or create
  25    another struct that the user ref()/unref().
  26
  27 * Stop using system() inside the library and use fork + exec instead
  28
  29 * config: configs that do not need to be matched by fnmatch() could be using a
  30   vector instead of a list. This way we could search in it by calling
  31   bsearch().
  32
  33 * index: drop the "open(), seek(), read()" implementation and use another one
  34   with mmap(). When lookup() is called and the file is not mmaped, mmap it.
  35
  36 * Implement actions in kmod tool like 'insert', 'remove', 'info', etc
  37
  38 Things to be added/removed in kernel (check what is really needed):
  39 ===================================================================
  40
  41 * list of currently loaded modules
  42         - readdir() in /sys/modules: dir without a 'initstate' file means the
  43           module is builtin.
  44
  45 * module's size should be available under /sys
  46         - DONE in 3.3: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
  47
  48 * kill /proc/modules ?
  49         - Unlikely, given other tools might depend on it
  50
  51 Things that are different from module-init-tools on purpose (!TODO)
  52 ===================================================================
  53
  54 modprobe
  55 --------
  56
  57 * 'modprobe -l' was marked as deprecated and does not exist anymore
  58
  59 * 'modprobe -t' is gone, together with 'modprobe -l'
  60
  61 * there's and additional '--remove-dependencies' flags to modprobe so we
  62   can remove modules depending on that one
  63
  64 * modprobe doesn't parse configuration files with names not ending in
  65   '.alias' or '.conf'. modprobe used to warn about these files.
  66
  67 * modprobe doesn't parse 'config' and 'include' commands in configuration
  68   files.
  69
  70 * modprobe from m-i-t does not honour softdeps for install commands. E.g.:
  71   config:
  72
  73         install bli "echo bli"
  74         install bla "echo bla"
  75         softdep bla pre: bli
  76
  77   With m-i-t, the output of 'modprobe --show-depends bla' will be:
  78         install "echo bla"
  79
  80   While with kmod:
  81         install "echo bli"
  82         install "echo bla"
  83
  84 * kmod doesn't dump the configuration as is in the config files. Instead it
  85   dumps the configuration as it was parsed. Therefore, comments and file names
  86   are not dumped, but on the good side we know what the exact configuration
  87   kmod is using. We did this because if we only want to know the entire content
  88   of configuration files, it's enough to use find(1) in modprobe.d directories
  89
  90 depmod
  91 ------
  92
  93 * there's no 'depmod -m' option: legacy modules.*map files are gone
  94
  95 lsmod
  96 -----
  97
  98 * information is parsed from /sys instead of /proc/modules
