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