Lucas De Marchi5e690c52011-12-16 02:02:58 -02002=========
Lucas De Marchibf89f762011-12-01 18:23:47 -02003
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
Lucas De Marchic3325cf2011-12-02 14:49:57 -02008* 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
Gustavo Sverzut Barbieric3d0a5f2011-12-11 19:36:18 -020011* create test-mock library to be LD_PRELOAD'ed before running the binaries
Gustavo Sverzut Barbieri7fe602b2011-12-10 13:32:27 -020012 so we're able to create unit tests
Gustavo Sverzut Barbieric3d0a5f2011-12-11 19:36:18 -020013
Gustavo Sverzut Barbieri674f8592011-12-20 11:54:53 -020014* 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
Lucas De Marchid89d7cb2012-01-12 18:14:32 -020025* 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
Gustavo Sverzut Barbierif841e632011-12-19 11:37:08 -020029* 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

47===========
48
Lucas De Marchi5e690c52011-12-16 02:02:58 -020049
Lucas De Marchi3af535c2011-12-27 17:32:55 -020050Things to be added/removed in kernel (check what is really needed):
Lucas De Marchi5e690c52011-12-16 02:02:58 -020051===================================================================
52
53* list of currently loaded modules
Lucas De Marchi758428a2012-01-16 15:56:17 -020054 - readdir() in /sys/modules: dirs without a 'initstate' file mean the
55 modules is builtin.
Lucas De Marchi5e690c52011-12-16 02:02:58 -020056
57* module's size should be available under /sys
Lucas De Marchi758428a2012-01-16 15:56:17 -020058 - DONE in 3.3: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=cca3e707301862ca9b9327e6a732463982f8cd1b
Lucas De Marchi5e690c52011-12-16 02:02:58 -020059
60* kill /proc/modules ?
Lucas De Marchi758428a2012-01-16 15:56:17 -020061 - Unlikely, given other tools might depend on it
Lucas De Marchi5a96c5f2012-01-01 05:47:17 -020062
63Things that are different from module-init-tools on purpose (!TODO)
64===================================================================
65
66modprobe
67--------
68
69* 'modprobe -l' was marked as deprecated and does not exist anymore
70
71* 'modprobe -t' is gone, together with 'modprobe -l'
72
73* there's and additional '--remove-dependencies' flags to kmod-modprobe so we
74 can remove modules depending on that one
75
76* kmod-modprobe doesn't parse configuration files whose name don't end on
77 '.alias' or '.conf'. modprobe used to warn about these files.
78
Lucas De Marchi0ad5dd02012-01-11 00:28:12 -020079* kmod-modprobe doesn't parse 'config' and 'include' commands in configuration
80 files.
81
Lucas De Marchi92122612012-01-11 21:48:08 -020082* we don't use <module-dir>/modules.builtin{,.bin} indexes. Instead we rely on
83 module appearing on /sys/modules/* without a initstate file to determine if
84 it is builtin.
85
Lucas De Marchif5643942012-01-12 14:45:11 -020086* modprobe from m-i-t does not honour softdeps for install commands. E.g.:
87 config:
88
89 install bli "echo bli"
90 install bla "echo bla"
91 softdep bla pre: bli
92
93 With m-i-t, the output of 'modprobe --show-depends bla' will be:
94 install "echo bla"
95
96 While with kmod:
97 install "echo bli"
98 install "echo bla"
99
Lucas De Marchibc434962012-01-13 02:35:34 -0200100* kmod doesn't dump the configuration as is in the config files. Instead it
101 dumps the configuration as it was parsed. Therefore, comments and file names
102 are not dumped, but on the good side we know what the exact configuration
103 kmod is using. We did this because if we only want to know the entire content
104 of configuration files, it's enough to use find(1) in modprobe.d directories
105
Lucas De Marchi5a96c5f2012-01-01 05:47:17 -0200106depmod
107------
108
109* there's no 'depmod -m' option: legacy modules.*map files are gone
Lucas De Marchie85b6732012-01-12 15:28:19 -0200110
111lsmod
112-----
113
114* information is parsed from /sys instead of /proc/modules
