   1 kmod 18
   2 =======
   3
   4 - Bug fixes:
   5         - Fix leaks in error paths
   6         - Fix use-after-free in hash implementation causing a wrong index to be
   7           generated by depmod with out-of-tree modules
   8
   9 - New features:
  10         - Calling depmod with modules creating a dependency loop will now make
  11           depmod return an error and not update the indexes. This is to protect
  12           the current index not being overridden by another index that may cause
  13           a boot failure, depending on the buggy module. It's a necessary
  14           change in behavior regarding previous kmod releases and
  15           module-init-tools. The error message was also improved to output
  16           the modules that caused the dependency cycle.
  17
  18 - Improvements to testsuite:
  19         - Fix and improve expected-fail test
  20         - Add tests for hashmap implementation
  21
  22 kmod 17
  23 =======
  24
  25 - Bug fixes:
  26         - Fix matching a "." in kernel cmdline, making garbage in the command
  27           line be parsed as kmod options
  28         - Fix man pages to clarify we don't fallback to parsing modules.dep
  29           but instead we depend on modules.dep.bin (generated by depmod) to
  30           be present
  31         - Fix ELF parsing on 32 bit systems assigning the wrong class.
  32         - Fix partial matches of search directives in depmod. Previously having
  33           a line in depmod.conf such as "search foo foobar built-in" would cause
  34           unpretictable results because foo is a partial match of foobar as well.
  35         - Fix unaligned access in modinfo when getting the signature from a
  36           module
  37         - Make sure softdeps are treated as optional dependencies
  38
  39 - New features:
  40         - Accept special files given to "-C" switch in modprobe. This way it's
  41           possible to skip system configuration with "modprobe -C /dev/null"
  42         - Do not require xsltproc on released tarballs
  43         - Don't use Werror anymore
  44         - Add experimental python bindings, merged from python-kmod repository
  45           (https://github.com/agrover/python-kmod)
  46         - Parse softdeps exported by the kernel as
  47           /lib/modules/`uname -r`/modules.softdep
  48
  49 - Improvements to testsuite:
  50         - Check the list of loaded modules after a test
  51
  52 kmod 16
  53 =======
  54
  55 - Bug fixes:
  56         - Fix usage of readdir_r()
  57         - Add some missing checks for memory allocation errors
  58
  59 - New features:
  60         - Remove option from libkmod to allow waiting on module removal if
  61           the module is being used. It's dangerous since it can block the
  62           caller indefinitely.
  63         - Improve compatibility with musl libc
  64         - Add fallback implementation for compilers without _Static_assert(),
  65           e.g. gcc < 4.6
  66         - Minor optimizations to the hash table
  67         - Make depmod warn if a module has incorrect devname specification
  68         - Use cleanup attribute
  69
  70 kmod 15
  71 =======
  72
  73 - Bug fixes:
  74         - kmod static-nodes doesn't fail if modules.devname isn't available
  75         - Fix getting boolean parameter from kernel cmdline in case the value
  76           is omitted
  77         - Fix some mkdir_p() corner cases (used in testsuite and static-nodes)
  78
  79 - New features:
  80         - kmod static-nodes creates parent directories if given a -o option
  81         - kmod binary statically links to libkmod - if distro is only interested
  82           in the kmod tool (for example in an initrd) it can refrain from
  83           installing the library
  84         - Add shell completion for kmod tool
  85
  86 kmod 14
  87 =======
  88
  89 - Bug fixes:
  90         - Fix some format strings
  91         - Protect against NULL being passed around to index
  92         - Avoid calling syscall() with -1 when finit_module() is not available,
  93           since this doesn't always work
  94         - Fix not being able to remove alias due to checking the module's
  95           refcount
  96         - Minor fixes and refactors
  97
  98 - New features:
  99         - Improve libkmod documentation, particularly on how flags are dealt
 100           with.
 101         - Remove ability to build a static libkmod
 102         - Add static-nodes command to kmod that parses modules.devname
 103           generating output in useful formats
 104
 105 kmod 13
 106 =======
 107
 108 - Bug fixes:
 109         - Add the long option --symbol-prefix option to depmod (it was absent)
 110           and fix its behavior
 111         - Don't abort if there's a bogus line in configuration file like "alias
 112           psmouse off". Some distros are carrying this since the days of
 113           modutils
 114
 115 - New features:
 116         - Add support for finit_module(2). If the module is load straight from
 117           the disk and without compression we use finit_module() syscall when
 118           available, falling back to init_module() otherwise
 119         - kmod_module_get_info() also returns the signature if the module is
 120           signed and modinfo uses it
 121         - Use secure_getenv if available
 122         - rmmod understands builtin modules, just like modprobe does
 123         - Improve compatibility with musl-libc
 124         - Test cases exit with success when receiving a signal if they are
 125           xfail tests
 126
 127 kmod 12
 128 =======
 129
 130 - Bug fixes:
 131         - Fix removing vermagic from module when told to force load a module
 132         - Fix removing __versions section when told to force load a module: we
 133           need to mangle the section header, not the section.
 134         - modinfo no longer fails while loading a module from file when path
 135           contains ".ko" substring
 136
 137 kmod 11
 138 =======
 139
 140 - Improvements to testsuite:
 141         - Fix testsuite defining symbols twice on 32 bit systems
 142         - Allow to check generated files against correct ones
 143
 144 - New features:
 145         - libkmod now keeps a file opened after the first call to
 146           kmod_module_get_{info,versions,symbols,dependency_symbols}. This
 147           reduces signficantly the amount of time depmod tool takes to
 148           execute. Particularly if compressed modules are used.
 149         - Remove --with-rootprefix from build system. It was not a great idea
 150           after all and should not be use since it causes more harm then
 151           benefits.
 152         - Hide --wait option on rmmod. This feature is being targeted for
 153           removal from kernel. rmmod still accepts this option, but it's hidden
 154           now: man page and usage() say nothing about it and if it's used,
 155           user will get a 10s sleep. This way we can check and help if anyone
 156           is using this feature.
 157         - Refactor message logging on all tools, giving proper prefix, routing
 158           everything to syslog when asked for, etc.
 159
 160 - Bug fixes:
 161         - Fix parsing of modules.order when using compressed modules
 162         - Usage messages go to stdout instead of stderr
 163         - Fix memory leak in hash implementation
 164
 165 kmod 10
 166 =======
 167
 168 - New features:
 169         - Read coresize from /sys if supported
 170
 171         - Add flag to kmod_module_probe_insert() to apply blacklisting during
 172           probe only if mod is an alias. Now modprobe uses this flag by default.
 173           This is needed to fix a change in behavior regarding module-init-tools
 174           and ultimately makes us loading a blacklisted module.
 175
 176 - Better formatting in man pages
 177
 178 - Add option to disable building man pages at build time
 179
 180 - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries
 181
 182 - Re-licensing testsuite as LGPL
 183
 184 kmod 9
 185 ======
 186
 187 - Improvements to the testsuite:
 188         - Check for correct handling of softdep loops
 189         - Check for correct handling of install command loops
 190
 191 - Bug fixes:
 192         - Fix build with compilers that don't support --gc-sections
 193         - Handle errors when dealing with gzipped modules
 194         - depmod now handles errors while writing indices, so it doesn't end up
 195           with a corrupted index without telling the user
 196
 197 kmod 8
 198 ======
 199
 200 - No new features, small bug fixes only.
 201         - Fix a bug in "modprobe -c" output: be compatible with
 202           module-init-tools
 203
 204         - Give a useful error message when init_module fails due to bad
 205           parameter or unknown symbols
 206
 207         - Fix doc generation
 208
 209 kmod 7
 210 ======
 211
 212 - Re-order dirs for configuration files to match the change in systemd and
 213   udev: now the priority is:
 214         1. /etc/modprobe.d
 215         2. /run/modprobe.d
 216         3. /lib/modprobe.d
 217
 218 - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not
 219   allowing the user to set his preferences.
 220
 221 - Bug fixes:
 222         - Return same error codes of module-init-tools when removing modules
 223           with modprobe
 224         - Fix builtin output in "--show-depends" when target kernel is not the
 225           same of the running kernel
 226         - 'modprobe -r' always look at all command line arguments
 227         - Fix '-q' usage in modprobe
 228
 229 kmod 6
 230 ======
 231
 232 - New API in libkmod:
 233         - kmod_module_apply_filter(): a generic function to apply filters in a
 234           list of modules. This deprecates the use of
 235           kmod_module_get_filtered_blacklist()
 236
 237 - More tests in testsuite
 238
 239 - Add compatibility with uClibc again
 240
 241 - Lookup modules.builtin.bin to decide if a module is built in kernel
 242
 243 - Downgrade some log messages so we don't annoy people with useless messages
 244
 245 - Bug fixes:
 246         - Flag --ignore-loaded was not being properly handled
 247         - Infinite loop with softdeps
 248         - Infinite loop with dumb user configuration with install commands
 249         - Fix leak in index when there's a partial match
 250
 251 - Move repository and tarballs to kernel.org
 252
 253 kmod 5
 254 ======
 255
 256 - Break libkmod's API to insert a module like modprobe does. It now accepts
 257   extra an extra argument to print its action and acceptable flags were
 258   sanitized.
 259
 260 - Share more code between modprobe and libkmod: using the new version of
 261   kmod_module_probe_insert_module() it's possible to share a great amount of
 262   code between modprobe and libkmod
 263
 264 - modprobe no longer works with paths: it only accepts module names and/or
 265   aliases now.
 266
 267 - testsuite was added to repository, allowing automated tests to be run and
 268   easing the way bugs are reproduced.
 269
 270 - modprobe: when dumping configuration ('-c' option) separate config
 271   and indexes by adding a commented line between them.
 272
 273 - Fix bugs wrt normalizing aliases and module names
 274
 275 - Fix bug wrt inserting an alias that resolves to multiple modules: we should
 276   not stop on the first error, but rather continue to try loading other
 277   modules.
 278
 279 - Fix unaligned memory access in hash function, causing depmod to output wrong
 280   information in ARMv5
 281
 282 - Fix man page build and install: now they are only installed if tools are
 283   enabled
 284
 285 kmod 4
 286 ======
 287
 288 - New APIs in libkmod to:
 289         - Get configuration lists: blacklists, install commands, remove
 290           commands, aliases, options and softdeps
 291         - Dump indexes
 292
 293 - Several bugs fixed in libkmod, modprobe, depmod and modinfo
 294
 295 - API documentation: if configure with run with --enable-gtk-doc, the API doc
 296   will be generated by make. Gtk-doc is required for that.
 297
 298 - Man pages are built, which replace man pages from module-init-tools
 299
 300 - 'include' and 'config' options in *.conf files were deprecated
 301
 302 - configure is not run by autogen.sh. Instead, a common set of options is
 303   printed. If you are hacking on kmod, consider using bootstrap-configure
 304   script.
 305
 306 - 'modprobe -c' works as expected now. As opposed to module-init-tools, it
 307   dumps the parsed configuration, not only the file contents.
 308
 309 kmod 3
 310 ======
 311
 312 - New APIs in libkmod to:
 313         - Get symbols from module, parsing the ELF section
 314         - Get dependency symbols
 315         - Check if resources are still valid or if libkmod must be reloaded
 316         - Insert module like modprobe, checking (soft-)dependencies, commands,
 317           blacklist. It can run commands by itself and to call a callback
 318           function.
 319
 320 - Support to load modules compressed with xz
 321
 322 - Tools are now bundled together in a single tool called kmod. It can be
 323   called using symlinks with the same names as tools from module-init-tools.
 324   E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
 325   1:1 replacement of module-init-tools.
 326
 327 - The only missing tool, depmod, was added to kmod together with the necessary
 328   APIs in libkmod.
 329
 330 - If a program using libkmod runs for a long time, as for example udev, it must
 331   check if it doesn't have to re-load libkmod. A new helper function was added
 332   in libkmod to check if context is still valid and udev is already using it.
 333
 334 - An 'unaligned access' bug was fixed. So those architecture that does not
 335   handle unaligned access can use kmod, too.
 336
 337 kmod 2
 338 ======
 339
 340 Some bugs fixed: the worst of them was with an infinite loop when an alias
 341 matched more than one module.
 342
 343 - New APIs in libkmod to:
 344         - Get soft dependencies
 345         - Get info from module files parsing ELF
 346         - Get modversions from files parsing ELF
 347
 348 - Support to load gzipped kernel modules: kmod can be compiled with support to
 349   gzipped modules by giving the --enable-zlib flag
 350
 351 - Support to forcefully load modules, both vermagic and modversion
 352
 353 - Support to force and nowait removal flags
 354
 355 - Configuration files are parsed in the same order as modprobe: files are
 356   sorted alphabetically (independently of their dir) and files with the same
 357   name obey a precedence order
 358
 359 - New tool: kmod-modinfo
 360
 361 - kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
 362   The only missing things are the options '--showconfig' and '-t / -l'. These
 363   last ones have been deprecated long ago and they will be removed from
 364   modprobe. A lot of effort has been put on kmod-modprobe to ensure it
 365   maintains compabitility with modprobe.
 366
 367 - linux-modules@vger.kernel.org became the official mailing list for kmod
 368
 369 kmod 1
 370 ======
 371
 372 First version of kmod and its library, libkmod.
 373
 374 In the libkmod it's currently possible to:
 375         - List modules currently loaded
 376         - Get information about loaded modules such as initstate, refcount,
 377           holders, sections, address and size
 378         - Lookup modules by alias, module name or path
 379         - Insert modules: options from configuration and extra options can be
 380           passed, but flags are not implemented, yet
 381         - Remove modules
 382         - Filter list of modules using blacklist
 383         - For each module, get the its list of options and install/remove
 384           commands
 385         - Indexes can be loaded on startup to speedup lookups later
 386
 387 Tools provided with the same set of options as in module-init-tools:
 388         - kmod-lsmod
 389         - kmod-insmod
 390         - kmod-rmmod
 391         - kmod-modprobe, with some functionality still missing (use of softdep,
 392           dump configuration, show modversions)
