   1 kmod 16
   2 =======
   3
   4 - New features:
   5         - Remove option from libkmod to allow waiting on module removal if
   6           the module is being used. It's dangerous since it can block the
   7           caller indefinitely.
   8
   9 kmod 15
  10 =======
  11
  12 - Bug fixes:
  13         - kmod static-nodes doesn't fail if modules.devname isn't available
  14         - Fix getting boolean parameter from kernel cmdline in case the value
  15           is omitted
  16         - Fix some mkdir_p() corner cases (used in testsuite and static-nodes)
  17
  18 - New features:
  19         - kmod static-nodes creates parent directories if given a -o option
  20         - kmod binary statically links to libkmod - if distro is only interested
  21           in the kmod tool (for example in an initrd) it can refrain from
  22           installing the library
  23         - Add shell completion for kmod tool
  24
  25 kmod 14
  26 =======
  27
  28 - Bug fixes:
  29         - Fix some format strings
  30         - Protect against NULL being passed around to index
  31         - Avoid calling syscall() with -1 when finit_module() is not available,
  32           since this doesn't always work
  33         - Fix not being able to remove alias due to checking the module's
  34           refcount
  35         - Minor fixes and refactors
  36
  37 - New features:
  38         - Improve libkmod documentation, particularly on how flags are dealt
  39           with.
  40         - Remove ability to build a static libkmod
  41         - Add static-nodes command to kmod that parses modules.devname
  42           generating output in useful formats
  43
  44 kmod 13
  45 =======
  46
  47 - Bug fixes:
  48         - Add the long option --symbol-prefix option to depmod (it was absent)
  49           and fix its behavior
  50         - Don't abort if there's a bogus line in configuration file like "alias
  51           psmouse off". Some distros are carrying this since the days of
  52           modutils
  53
  54 - New features:
  55         - Add support for finit_module(2). If the module is load straight from
  56           the disk and without compression we use finit_module() syscall when
  57           available, falling back to init_module() otherwise
  58         - kmod_module_get_info() also returns the signature if the module is
  59           signed and modinfo uses it
  60         - Use secure_getenv if available
  61         - rmmod understands builtin modules, just like modprobe does
  62         - Improve compatibility with musl-libc
  63         - Test cases exit with success when receiving a signal if they are
  64           xfail tests
  65
  66 kmod 12
  67 =======
  68
  69 - Bug fixes:
  70         - Fix removing vermagic from module when told to force load a module
  71         - Fix removing __versions section when told to force load a module: we
  72           need to mangle the section header, not the section.
  73         - modinfo no longer fails while loading a module from file when path
  74           contains ".ko" substring
  75
  76 kmod 11
  77 =======
  78
  79 - Improvements to testsuite:
  80         - Fix testsuite defining symbols twice on 32 bit systems
  81         - Allow to check generated files against correct ones
  82
  83 - New features:
  84         - libkmod now keeps a file opened after the first call to
  85           kmod_module_get_{info,versions,symbols,dependency_symbols}. This
  86           reduces signficantly the amount of time depmod tool takes to
  87           execute. Particularly if compressed modules are used.
  88         - Remove --with-rootprefix from build system. It was not a great idea
  89           after all and should not be use since it causes more harm then
  90           benefits.
  91         - Hide --wait option on rmmod. This feature is being targeted for
  92           removal from kernel. rmmod still accepts this option, but it's hidden
  93           now: man page and usage() say nothing about it and if it's used,
  94           user will get a 10s sleep. This way we can check and help if anyone
  95           is using this feature.
  96         - Refactor message logging on all tools, giving proper prefix, routing
  97           everything to syslog when asked for, etc.
  98
  99 - Bug fixes:
 100         - Fix parsing of modules.order when using compressed modules
 101         - Usage messages go to stdout instead of stderr
 102         - Fix memory leak in hash implementation
 103
 104 kmod 10
 105 =======
 106
 107 - New features:
 108         - Read coresize from /sys if supported
 109
 110         - Add flag to kmod_module_probe_insert() to apply blacklisting during
 111           probe only if mod is an alias. Now modprobe uses this flag by default.
 112           This is needed to fix a change in behavior regarding module-init-tools
 113           and ultimately makes us loading a blacklisted module.
 114
 115 - Better formatting in man pages
 116
 117 - Add option to disable building man pages at build time
 118
 119 - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries
 120
 121 - Re-licensing testsuite as LGPL
 122
 123 kmod 9
 124 ======
 125
 126 - Improvements to the testsuite:
 127         - Check for correct handling of softdep loops
 128         - Check for correct handling of install command loops
 129
 130 - Bug fixes:
 131         - Fix build with compilers that don't support --gc-sections
 132         - Handle errors when dealing with gzipped modules
 133         - depmod now handles errors while writing indices, so it doesn't end up
 134           with a corrupted index without telling the user
 135
 136 kmod 8
 137 ======
 138
 139 - No new features, small bug fixes only.
 140         - Fix a bug in "modprobe -c" output: be compatible with
 141           module-init-tools
 142
 143         - Give a useful error message when init_module fails due to bad
 144           parameter or unknown symbols
 145
 146         - Fix doc generation
 147
 148 kmod 7
 149 ======
 150
 151 - Re-order dirs for configuration files to match the change in systemd and
 152   udev: now the priority is:
 153         1. /etc/modprobe.d
 154         2. /run/modprobe.d
 155         3. /lib/modprobe.d
 156
 157 - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not
 158   allowing the user to set his preferences.
 159
 160 - Bug fixes:
 161         - Return same error codes of module-init-tools when removing modules
 162           with modprobe
 163         - Fix builtin output in "--show-depends" when target kernel is not the
 164           same of the running kernel
 165         - 'modprobe -r' always look at all command line arguments
 166         - Fix '-q' usage in modprobe
 167
 168 kmod 6
 169 ======
 170
 171 - New API in libkmod:
 172         - kmod_module_apply_filter(): a generic function to apply filters in a
 173           list of modules. This deprecates the use of
 174           kmod_module_get_filtered_blacklist()
 175
 176 - More tests in testsuite
 177
 178 - Add compatibility with uClibc again
 179
 180 - Lookup modules.builtin.bin to decide if a module is built in kernel
 181
 182 - Downgrade some log messages so we don't annoy people with useless messages
 183
 184 - Bug fixes:
 185         - Flag --ignore-loaded was not being properly handled
 186         - Infinite loop with softdeps
 187         - Infinite loop with dumb user configuration with install commands
 188         - Fix leak in index when there's a partial match
 189
 190 - Move repository and tarballs to kernel.org
 191
 192 kmod 5
 193 ======
 194
 195 - Break libkmod's API to insert a module like modprobe does. It now accepts
 196   extra an extra argument to print its action and acceptable flags were
 197   sanitized.
 198
 199 - Share more code between modprobe and libkmod: using the new version of
 200   kmod_module_probe_insert_module() it's possible to share a great amount of
 201   code between modprobe and libkmod
 202
 203 - modprobe no longer works with paths: it only accepts module names and/or
 204   aliases now.
 205
 206 - testsuite was added to repository, allowing automated tests to be run and
 207   easing the way bugs are reproduced.
 208
 209 - modprobe: when dumping configuration ('-c' option) separate config
 210   and indexes by adding a commented line between them.
 211
 212 - Fix bugs wrt normalizing aliases and module names
 213
 214 - Fix bug wrt inserting an alias that resolves to multiple modules: we should
 215   not stop on the first error, but rather continue to try loading other
 216   modules.
 217
 218 - Fix unaligned memory access in hash function, causing depmod to output wrong
 219   information in ARMv5
 220
 221 - Fix man page build and install: now they are only installed if tools are
 222   enabled
 223
 224 kmod 4
 225 ======
 226
 227 - New APIs in libkmod to:
 228         - Get configuration lists: blacklists, install commands, remove
 229           commands, aliases, options and softdeps
 230         - Dump indexes
 231
 232 - Several bugs fixed in libkmod, modprobe, depmod and modinfo
 233
 234 - API documentation: if configure with run with --enable-gtk-doc, the API doc
 235   will be generated by make. Gtk-doc is required for that.
 236
 237 - Man pages are built, which replace man pages from module-init-tools
 238
 239 - 'include' and 'config' options in *.conf files were deprecated
 240
 241 - configure is not run by autogen.sh. Instead, a common set of options is
 242   printed. If you are hacking on kmod, consider using bootstrap-configure
 243   script.
 244
 245 - 'modprobe -c' works as expected now. As opposed to module-init-tools, it
 246   dumps the parsed configuration, not only the file contents.
 247
 248 kmod 3
 249 ======
 250
 251 - New APIs in libkmod to:
 252         - Get symbols from module, parsing the ELF section
 253         - Get dependency symbols
 254         - Check if resources are still valid or if libkmod must be reloaded
 255         - Insert module like modprobe, checking (soft-)dependencies, commands,
 256           blacklist. It can run commands by itself and to call a callback
 257           function.
 258
 259 - Support to load modules compressed with xz
 260
 261 - Tools are now bundled together in a single tool called kmod. It can be
 262   called using symlinks with the same names as tools from module-init-tools.
 263   E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
 264   1:1 replacement of module-init-tools.
 265
 266 - The only missing tool, depmod, was added to kmod together with the necessary
 267   APIs in libkmod.
 268
 269 - If a program using libkmod runs for a long time, as for example udev, it must
 270   check if it doesn't have to re-load libkmod. A new helper function was added
 271   in libkmod to check if context is still valid and udev is already using it.
 272
 273 - An 'unaligned access' bug was fixed. So those architecture that does not
 274   handle unaligned access can use kmod, too.
 275
 276 kmod 2
 277 ======
 278
 279 Some bugs fixed: the worst of them was with an infinite loop when an alias
 280 matched more than one module.
 281
 282 - New APIs in libkmod to:
 283         - Get soft dependencies
 284         - Get info from module files parsing ELF
 285         - Get modversions from files parsing ELF
 286
 287 - Support to load gzipped kernel modules: kmod can be compiled with support to
 288   gzipped modules by giving the --enable-zlib flag
 289
 290 - Support to forcefully load modules, both vermagic and modversion
 291
 292 - Support to force and nowait removal flags
 293
 294 - Configuration files are parsed in the same order as modprobe: files are
 295   sorted alphabetically (independently of their dir) and files with the same
 296   name obey a precedence order
 297
 298 - New tool: kmod-modinfo
 299
 300 - kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
 301   The only missing things are the options '--showconfig' and '-t / -l'. These
 302   last ones have been deprecated long ago and they will be removed from
 303   modprobe. A lot of effort has been put on kmod-modprobe to ensure it
 304   maintains compabitility with modprobe.
 305
 306 - linux-modules@vger.kernel.org became the official mailing list for kmod
 307
 308 kmod 1
 309 ======
 310
 311 First version of kmod and its library, libkmod.
 312
 313 In the libkmod it's currently possible to:
 314         - List modules currently loaded
 315         - Get information about loaded modules such as initstate, refcount,
 316           holders, sections, address and size
 317         - Lookup modules by alias, module name or path
 318         - Insert modules: options from configuration and extra options can be
 319           passed, but flags are not implemented, yet
 320         - Remove modules
 321         - Filter list of modules using blacklist
 322         - For each module, get the its list of options and install/remove
 323           commands
 324         - Indexes can be loaded on startup to speedup lookups later
 325
 326 Tools provided with the same set of options as in module-init-tools:
 327         - kmod-lsmod
 328         - kmod-insmod
 329         - kmod-rmmod
 330         - kmod-modprobe, with some functionality still missing (use of softdep,
 331           dump configuration, show modversions)
