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