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