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