   1 kmod 19
   2 =======
   3
   4 - Bug fixes:
   5         - Fix missing CLOEXEC in library
   6         - Fix error message while opening kmod's index
   7
   8 - New features:
   9         - Add kmod(8) man page
  10         - Allow to build with libc's without be32toh()
  11         - Move code around separating common code and data structures into a
  12           shared directory. This allows to share more code between library and
  13           tools, making the binary size of tools shorter.
  14         - Clarify tools vs library licenses
  15         - static-nodes: when writting in tmpfiles format, indicate that
  16           creation of static nodes should only happen at boot. This is used and
  17           required by systemd-217+.
  18
  19 - Improvements to testsuite:
  20         - Add tests for newly created shared/ code
  21         - Improve how tests are declared so there's less boilerplate code for
  22           each test.
  23
  24 kmod 18
  25 =======
  26
  27 - Bug fixes:
  28         - Fix leaks in error paths
  29         - Fix use-after-free in hash implementation causing a wrong index to be
  30           generated by depmod with out-of-tree modules
  31
  32 - New features:
  33         - Calling depmod with modules creating a dependency loop will now make
  34           depmod return an error and not update the indexes. This is to protect
  35           the current index not being overridden by another index that may cause
  36           a boot failure, depending on the buggy module. It's a necessary
  37           change in behavior regarding previous kmod releases and
  38           module-init-tools. The error message was also improved to output
  39           the modules that caused the dependency cycle.
  40
  41 - Improvements to testsuite:
  42         - Fix and improve expected-fail test
  43         - Add tests for hashmap implementation
  44
  45 kmod 17
  46 =======
  47
  48 - Bug fixes:
  49         - Fix matching a "." in kernel cmdline, making garbage in the command
  50           line be parsed as kmod options
  51         - Fix man pages to clarify we don't fallback to parsing modules.dep
  52           but instead we depend on modules.dep.bin (generated by depmod) to
  53           be present
  54         - Fix ELF parsing on 32 bit systems assigning the wrong class.
  55         - Fix partial matches of search directives in depmod. Previously having
  56           a line in depmod.conf such as "search foo foobar built-in" would cause
  57           unpretictable results because foo is a partial match of foobar as well.
  58         - Fix unaligned access in modinfo when getting the signature from a
  59           module
  60         - Make sure softdeps are treated as optional dependencies
  61
  62 - New features:
  63         - Accept special files given to "-C" switch in modprobe. This way it's
  64           possible to skip system configuration with "modprobe -C /dev/null"
  65         - Do not require xsltproc on released tarballs
  66         - Don't use Werror anymore
  67         - Add experimental python bindings, merged from python-kmod repository
  68           (https://github.com/agrover/python-kmod)
  69         - Parse softdeps exported by the kernel as
  70           /lib/modules/`uname -r`/modules.softdep
  71
  72 - Improvements to testsuite:
  73         - Check the list of loaded modules after a test
  74
  75 kmod 16
  76 =======
  77
  78 - Bug fixes:
  79         - Fix usage of readdir_r()
  80         - Add some missing checks for memory allocation errors
  81
  82 - New features:
  83         - Remove option from libkmod to allow waiting on module removal if
  84           the module is being used. It's dangerous since it can block the
  85           caller indefinitely.
  86         - Improve compatibility with musl libc
  87         - Add fallback implementation for compilers without _Static_assert(),
  88           e.g. gcc < 4.6
  89         - Minor optimizations to the hash table
  90         - Make depmod warn if a module has incorrect devname specification
  91         - Use cleanup attribute
  92
  93 kmod 15
  94 =======
  95
  96 - Bug fixes:
  97         - kmod static-nodes doesn't fail if modules.devname isn't available
  98         - Fix getting boolean parameter from kernel cmdline in case the value
  99           is omitted
 100         - Fix some mkdir_p() corner cases (used in testsuite and static-nodes)
 101
 102 - New features:
 103         - kmod static-nodes creates parent directories if given a -o option
 104         - kmod binary statically links to libkmod - if distro is only interested
 105           in the kmod tool (for example in an initrd) it can refrain from
 106           installing the library
 107         - Add shell completion for kmod tool
 108
 109 kmod 14
 110 =======
 111
 112 - Bug fixes:
 113         - Fix some format strings
 114         - Protect against NULL being passed around to index
 115         - Avoid calling syscall() with -1 when finit_module() is not available,
 116           since this doesn't always work
 117         - Fix not being able to remove alias due to checking the module's
 118           refcount
 119         - Minor fixes and refactors
 120
 121 - New features:
 122         - Improve libkmod documentation, particularly on how flags are dealt
 123           with.
 124         - Remove ability to build a static libkmod
 125         - Add static-nodes command to kmod that parses modules.devname
 126           generating output in useful formats
 127
 128 kmod 13
 129 =======
 130
 131 - Bug fixes:
 132         - Add the long option --symbol-prefix option to depmod (it was absent)
 133           and fix its behavior
 134         - Don't abort if there's a bogus line in configuration file like "alias
 135           psmouse off". Some distros are carrying this since the days of
 136           modutils
 137
 138 - New features:
 139         - Add support for finit_module(2). If the module is load straight from
 140           the disk and without compression we use finit_module() syscall when
 141           available, falling back to init_module() otherwise
 142         - kmod_module_get_info() also returns the signature if the module is
 143           signed and modinfo uses it
 144         - Use secure_getenv if available
 145         - rmmod understands builtin modules, just like modprobe does
 146         - Improve compatibility with musl-libc
 147         - Test cases exit with success when receiving a signal if they are
 148           xfail tests
 149
 150 kmod 12
 151 =======
 152
 153 - Bug fixes:
 154         - Fix removing vermagic from module when told to force load a module
 155         - Fix removing __versions section when told to force load a module: we
 156           need to mangle the section header, not the section.
 157         - modinfo no longer fails while loading a module from file when path
 158           contains ".ko" substring
 159
 160 kmod 11
 161 =======
 162
 163 - Improvements to testsuite:
 164         - Fix testsuite defining symbols twice on 32 bit systems
 165         - Allow to check generated files against correct ones
 166
 167 - New features:
 168         - libkmod now keeps a file opened after the first call to
 169           kmod_module_get_{info,versions,symbols,dependency_symbols}. This
 170           reduces signficantly the amount of time depmod tool takes to
 171           execute. Particularly if compressed modules are used.
 172         - Remove --with-rootprefix from build system. It was not a great idea
 173           after all and should not be use since it causes more harm then
 174           benefits.
 175         - Hide --wait option on rmmod. This feature is being targeted for
 176           removal from kernel. rmmod still accepts this option, but it's hidden
 177           now: man page and usage() say nothing about it and if it's used,
 178           user will get a 10s sleep. This way we can check and help if anyone
 179           is using this feature.
 180         - Refactor message logging on all tools, giving proper prefix, routing
 181           everything to syslog when asked for, etc.
 182
 183 - Bug fixes:
 184         - Fix parsing of modules.order when using compressed modules
 185         - Usage messages go to stdout instead of stderr
 186         - Fix memory leak in hash implementation
 187
 188 kmod 10
 189 =======
 190
 191 - New features:
 192         - Read coresize from /sys if supported
 193
 194         - Add flag to kmod_module_probe_insert() to apply blacklisting during
 195           probe only if mod is an alias. Now modprobe uses this flag by default.
 196           This is needed to fix a change in behavior regarding module-init-tools
 197           and ultimately makes us loading a blacklisted module.
 198
 199 - Better formatting in man pages
 200
 201 - Add option to disable building man pages at build time
 202
 203 - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries
 204
 205 - Re-licensing testsuite as LGPL
 206
 207 kmod 9
 208 ======
 209
 210 - Improvements to the testsuite:
 211         - Check for correct handling of softdep loops
 212         - Check for correct handling of install command loops
 213
 214 - Bug fixes:
 215         - Fix build with compilers that don't support --gc-sections
 216         - Handle errors when dealing with gzipped modules
 217         - depmod now handles errors while writing indices, so it doesn't end up
 218           with a corrupted index without telling the user
 219
 220 kmod 8
 221 ======
 222
 223 - No new features, small bug fixes only.
 224         - Fix a bug in "modprobe -c" output: be compatible with
 225           module-init-tools
 226
 227         - Give a useful error message when init_module fails due to bad
 228           parameter or unknown symbols
 229
 230         - Fix doc generation
 231
 232 kmod 7
 233 ======
 234
 235 - Re-order dirs for configuration files to match the change in systemd and
 236   udev: now the priority is:
 237         1. /etc/modprobe.d
 238         2. /run/modprobe.d
 239         3. /lib/modprobe.d
 240
 241 - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not
 242   allowing the user to set his preferences.
 243
 244 - Bug fixes:
 245         - Return same error codes of module-init-tools when removing modules
 246           with modprobe
 247         - Fix builtin output in "--show-depends" when target kernel is not the
 248           same of the running kernel
 249         - 'modprobe -r' always look at all command line arguments
 250         - Fix '-q' usage in modprobe
 251
 252 kmod 6
 253 ======
 254
 255 - New API in libkmod:
 256         - kmod_module_apply_filter(): a generic function to apply filters in a
 257           list of modules. This deprecates the use of
 258           kmod_module_get_filtered_blacklist()
 259
 260 - More tests in testsuite
 261
 262 - Add compatibility with uClibc again
 263
 264 - Lookup modules.builtin.bin to decide if a module is built in kernel
 265
 266 - Downgrade some log messages so we don't annoy people with useless messages
 267
 268 - Bug fixes:
 269         - Flag --ignore-loaded was not being properly handled
 270         - Infinite loop with softdeps
 271         - Infinite loop with dumb user configuration with install commands
 272         - Fix leak in index when there's a partial match
 273
 274 - Move repository and tarballs to kernel.org
 275
 276 kmod 5
 277 ======
 278
 279 - Break libkmod's API to insert a module like modprobe does. It now accepts
 280   extra an extra argument to print its action and acceptable flags were
 281   sanitized.
 282
 283 - Share more code between modprobe and libkmod: using the new version of
 284   kmod_module_probe_insert_module() it's possible to share a great amount of
 285   code between modprobe and libkmod
 286
 287 - modprobe no longer works with paths: it only accepts module names and/or
 288   aliases now.
 289
 290 - testsuite was added to repository, allowing automated tests to be run and
 291   easing the way bugs are reproduced.
 292
 293 - modprobe: when dumping configuration ('-c' option) separate config
 294   and indexes by adding a commented line between them.
 295
 296 - Fix bugs wrt normalizing aliases and module names
 297
 298 - Fix bug wrt inserting an alias that resolves to multiple modules: we should
 299   not stop on the first error, but rather continue to try loading other
 300   modules.
 301
 302 - Fix unaligned memory access in hash function, causing depmod to output wrong
 303   information in ARMv5
 304
 305 - Fix man page build and install: now they are only installed if tools are
 306   enabled
 307
 308 kmod 4
 309 ======
 310
 311 - New APIs in libkmod to:
 312         - Get configuration lists: blacklists, install commands, remove
 313           commands, aliases, options and softdeps
 314         - Dump indexes
 315
 316 - Several bugs fixed in libkmod, modprobe, depmod and modinfo
 317
 318 - API documentation: if configure with run with --enable-gtk-doc, the API doc
 319   will be generated by make. Gtk-doc is required for that.
 320
 321 - Man pages are built, which replace man pages from module-init-tools
 322
 323 - 'include' and 'config' options in *.conf files were deprecated
 324
 325 - configure is not run by autogen.sh. Instead, a common set of options is
 326   printed. If you are hacking on kmod, consider using bootstrap-configure
 327   script.
 328
 329 - 'modprobe -c' works as expected now. As opposed to module-init-tools, it
 330   dumps the parsed configuration, not only the file contents.
 331
 332 kmod 3
 333 ======
 334
 335 - New APIs in libkmod to:
 336         - Get symbols from module, parsing the ELF section
 337         - Get dependency symbols
 338         - Check if resources are still valid or if libkmod must be reloaded
 339         - Insert module like modprobe, checking (soft-)dependencies, commands,
 340           blacklist. It can run commands by itself and to call a callback
 341           function.
 342
 343 - Support to load modules compressed with xz
 344
 345 - Tools are now bundled together in a single tool called kmod. It can be
 346   called using symlinks with the same names as tools from module-init-tools.
 347   E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
 348   1:1 replacement of module-init-tools.
 349
 350 - The only missing tool, depmod, was added to kmod together with the necessary
 351   APIs in libkmod.
 352
 353 - If a program using libkmod runs for a long time, as for example udev, it must
 354   check if it doesn't have to re-load libkmod. A new helper function was added
 355   in libkmod to check if context is still valid and udev is already using it.
 356
 357 - An 'unaligned access' bug was fixed. So those architecture that does not
 358   handle unaligned access can use kmod, too.
 359
 360 kmod 2
 361 ======
 362
 363 Some bugs fixed: the worst of them was with an infinite loop when an alias
 364 matched more than one module.
 365
 366 - New APIs in libkmod to:
 367         - Get soft dependencies
 368         - Get info from module files parsing ELF
 369         - Get modversions from files parsing ELF
 370
 371 - Support to load gzipped kernel modules: kmod can be compiled with support to
 372   gzipped modules by giving the --enable-zlib flag
 373
 374 - Support to forcefully load modules, both vermagic and modversion
 375
 376 - Support to force and nowait removal flags
 377
 378 - Configuration files are parsed in the same order as modprobe: files are
 379   sorted alphabetically (independently of their dir) and files with the same
 380   name obey a precedence order
 381
 382 - New tool: kmod-modinfo
 383
 384 - kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
 385   The only missing things are the options '--showconfig' and '-t / -l'. These
 386   last ones have been deprecated long ago and they will be removed from
 387   modprobe. A lot of effort has been put on kmod-modprobe to ensure it
 388   maintains compabitility with modprobe.
 389
 390 - linux-modules@vger.kernel.org became the official mailing list for kmod
 391
 392 kmod 1
 393 ======
 394
 395 First version of kmod and its library, libkmod.
 396
 397 In the libkmod it's currently possible to:
 398         - List modules currently loaded
 399         - Get information about loaded modules such as initstate, refcount,
 400           holders, sections, address and size
 401         - Lookup modules by alias, module name or path
 402         - Insert modules: options from configuration and extra options can be
 403           passed, but flags are not implemented, yet
 404         - Remove modules
 405         - Filter list of modules using blacklist
 406         - For each module, get the its list of options and install/remove
 407           commands
 408         - Indexes can be loaded on startup to speedup lookups later
 409
 410 Tools provided with the same set of options as in module-init-tools:
 411         - kmod-lsmod
 412         - kmod-insmod
 413         - kmod-rmmod
 414         - kmod-modprobe, with some functionality still missing (use of softdep,
 415           dump configuration, show modversions)
