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