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