   1 kmod 12
   2 =======
   3
   4 - Bug fixes:
   5         - Fix removing vermagic from module when told to force load a module
   6         - Fix removing __versions section when told to force load a module: we
   7           need to mangle the section header, not the section.
   8         - modinfo no longer fails while loading a module from file when path
   9           contains ".ko" substring
  10
  11 kmod 11
  12 =======
  13
  14 - Improvements to testsuite:
  15         - Fix testsuite defining symbols twice on 32 bit systems
  16         - Allow to check generated files against correct ones
  17
  18 - New features:
  19         - libkmod now keeps a file opened after the first call to
  20           kmod_module_get_{info,versions,symbols,dependency_symbols}. This
  21           reduces signficantly the amount of time depmod tool takes to
  22           execute. Particularly if compressed modules are used.
  23         - Remove --with-rootprefix from build system. It was not a great idea
  24           after all and should not be use since it causes more harm then
  25           benefits.
  26         - Hide --wait option on rmmod. This feature is being targeted for
  27           removal from kernel. rmmod still accepts this option, but it's hidden
  28           now: man page and usage() says nothing about it and if it's used,
  29           user will get a 10s sleep. This way we can check and help if anyone
  30           is using this feature.
  31         - Refactor message logging on all tools, giving proper prefix, routing
  32           everything to syslog when asked for, etc.
  33
  34 - Bug fixes:
  35         - Fix parsing of modules.order when using compressed modules
  36         - Usage messages go to stdout instead of stderr
  37         - Fix memory leak in hash implementation
  38
  39 kmod 10
  40 =======
  41
  42 - New features:
  43         - Read coresize from /sys if supported
  44
  45         - Add flag to kmod_module_probe_insert() to apply blacklisting during
  46           probe only if mod is an alias. Now modprobe uses this flag by default.
  47           This is needed to fix a change in behavior regarding module-init-tools
  48           and ultimately makes us loading a blacklisted module.
  49
  50 - Better formatting in man pages
  51
  52 - Add option to disable building man pages at build time
  53
  54 - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries
  55
  56 - Re-licensing testsuite as LGPL
  57
  58 kmod 9
  59 ======
  60
  61 - Improvements to the testsuite:
  62         - Check for correct handling of softdep loops
  63         - Check for correct handling of install command loops
  64
  65 - Bug fixes:
  66         - Fix build with compilers that don't support --gc-sections
  67         - Handle errors when dealing with gzipped modules
  68         - depmod now handles errors while writing indices, so it doesn't end up
  69           with a corrupted index without telling the user
  70
  71 kmod 8
  72 ======
  73
  74 - No new features, small bug fixes only.
  75         - Fix a bug in "modprobe -c" output: be compatible with
  76           module-init-tools
  77
  78         - Give a useful error message when init_module fails due to bad
  79           parameter or unknown symbols
  80
  81         - Fix doc generation
  82
  83 kmod 7
  84 ======
  85
  86 - Re-order dirs for configuration files to match the change in systemd and
  87   udev: now the priority is:
  88         1. /etc/modprobe.d
  89         2. /run/modprobe.d
  90         3. /lib/modprobe.d
  91
  92 - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not
  93   allowing the user to set his preferences.
  94
  95 - Bug fixes:
  96         - Return same error codes of module-init-tools when removing modules
  97           with modprobe
  98         - Fix builtin output in "--show-depends" when target kernel is not the
  99           same of the running kernel
 100         - 'modprobe -r' always look at all command line arguments
 101         - Fix '-q' usage in modprobe
 102
 103 kmod 6
 104 ======
 105
 106 - New API in libkmod:
 107         - kmod_module_apply_filter(): a generic function to apply filters in a
 108           list of modules. This deprecates the use of
 109           kmod_module_get_filtered_blacklist()
 110
 111 - More tests in testsuite
 112
 113 - Add compatibility with uClibc again
 114
 115 - Lookup modules.builtin.bin to decide if a module is built in kernel
 116
 117 - Downgrade some log messages so we don't annoy people with useless messages
 118
 119 - Bug fixes:
 120         - Flag --ignore-loaded was not being properly handled
 121         - Infinite loop with softdeps
 122         - Infinite loop with dumb user configuration with install commands
 123         - Fix leak in index when there's a partial match
 124
 125 - Move repository and tarballs to kernel.org
 126
 127 kmod 5
 128 ======
 129
 130 - Break libkmod's API to insert a module like modprobe does. It now accepts
 131   extra an extra argument to print its action and acceptable flags were
 132   sanitized.
 133
 134 - Share more code between modprobe and libkmod: using the new version of
 135   kmod_module_probe_insert_module() it's possible to share a great amount of
 136   code between modprobe and libkmod
 137
 138 - modprobe no longer works with paths: it only accepts module names and/or
 139   aliases now.
 140
 141 - testsuite was added to repository, allowing automated tests to be run and
 142   easing the way bugs are reproduced.
 143
 144 - modprobe: when dumping configuration ('-c' option) separate config
 145   and indexes by adding a commented line between them.
 146
 147 - Fix bugs wrt normalizing aliases and module names
 148
 149 - Fix bug wrt inserting an alias that resolves to multiple modules: we should
 150   not stop on the first error, but rather continue to try loading other
 151   modules.
 152
 153 - Fix unaligned memory access in hash function, causing depmod to output wrong
 154   information in ARMv5
 155
 156 - Fix man page build and install: now they are only installed if tools are
 157   enabled
 158
 159 kmod 4
 160 ======
 161
 162 - New APIs in libkmod to:
 163         - Get configuration lists: blacklists, install commands, remove
 164           commands, aliases, options and softdeps
 165         - Dump indexes
 166
 167 - Several bugs fixed in libkmod, modprobe, depmod and modinfo
 168
 169 - API documentation: if configure with run with --enable-gtk-doc, the API doc
 170   will be generated by make. Gtk-doc is required for that.
 171
 172 - Man pages are built, which replace man pages from module-init-tools
 173
 174 - 'include' and 'config' options in *.conf files were deprecated
 175
 176 - configure is not run by autogen.sh. Instead, a common set of options is
 177   printed. If you are hacking on kmod, consider using bootstrap-configure
 178   script.
 179
 180 - 'modprobe -c' works as expected now. As opposed to module-init-tools, it
 181   dumps the parsed configuration, not only the file contents.
 182
 183 kmod 3
 184 ======
 185
 186 - New APIs in libkmod to:
 187         - Get symbols from module, parsing the ELF section
 188         - Get dependency symbols
 189         - Check if resources are still valid or if libkmod must be reloaded
 190         - Insert module like modprobe, checking (soft-)dependencies, commands,
 191           blacklist. It can run commands by itself and to call a callback
 192           function.
 193
 194 - Support to load modules compressed with xz
 195
 196 - Tools are now bundled together in a single tool called kmod. It can be
 197   called using symlinks with the same names as tools from module-init-tools.
 198   E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
 199   1:1 replacement of module-init-tools.
 200
 201 - The only missing tool, depmod, was added to kmod together with the necessary
 202   APIs in libkmod.
 203
 204 - If a program using libkmod runs for a long time, as for example udev, it must
 205   check if it doesn't have to re-load libkmod. A new helper function was added
 206   in libkmod to check if context is still valid and udev is already using it.
 207
 208 - An 'unaligned access' bug was fixed. So those architecture that does not
 209   handle unaligned access can use kmod, too.
 210
 211 kmod 2
 212 ======
 213
 214 Some bugs fixed: the worst of them was with an infinite loop when an alias
 215 matched more than one module.
 216
 217 - New APIs in libkmod to:
 218         - Get soft dependencies
 219         - Get info from module files parsing ELF
 220         - Get modversions from files parsing ELF
 221
 222 - Support to load gzipped kernel modules: kmod can be compiled with support to
 223   gzipped modules by giving the --enable-zlib flag
 224
 225 - Support to forcefully load modules, both vermagic and modversion
 226
 227 - Support to force and nowait removal flags
 228
 229 - Configuration files are parsed in the same order as modprobe: files are
 230   sorted alphabetically (independently of their dir) and files with the same
 231   name obey a precedence order
 232
 233 - New tool: kmod-modinfo
 234
 235 - kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
 236   The only missing things are the options '--showconfig' and '-t / -l'. These
 237   last ones have been deprecated long ago and they will be removed from
 238   modprobe. A lot of effort has been put on kmod-modprobe to ensure it
 239   maintains compabitility with modprobe.
 240
 241 - linux-modules@vger.kernel.org became the official mailing list for kmod
 242
 243 kmod 1
 244 ======
 245
 246 First version of kmod and its library, libkmod.
 247
 248 In the libkmod it's currently possible to:
 249         - List modules currently loaded
 250         - Get information about loaded modules such as initstate, refcount,
 251           holders, sections, address and size
 252         - Lookup modules by alias, module name or path
 253         - Insert modules: options from configuration and extra options can be
 254           passed, but flags are not implemented, yet
 255         - Remove modules
 256         - Filter list of modules using blacklist
 257         - For each module, get the its list of options and install/remove
 258           commands
 259         - Indexes can be loaded on startup to speedup lookups later
 260
 261 Tools provided with the same set of options as in module-init-tools:
 262         - kmod-lsmod
 263         - kmod-insmod
 264         - kmod-rmmod
 265         - kmod-modprobe, with some functionality still missing (use of softdep,
 266           dump configuration, show modversions)
