4 - Handle bogus values from ELF, making sure they don't overflow while
6 - Fix leak in depmod when -b flag is passed multiple times
7 - Multiple minor fixes from static analysis by coverity and
9 - Fix race between loading modules and checking if it's loaded in the
13 - There's a change in behavior regarding builtin modules: we now only
14 consider as builtin those that are present in modules.builtin index.
15 Previously we were also checking the presence of
16 /sys/module/<module-name>, but this is racy and only modules that
17 contain parameters are the ones creating a directory in sysfs.
19 Now some commands will start to fail, e.g. "modprobe vt". Since vt
20 can't be compiled as a module it's not present in modules.builtin
21 index. Previously we would report at as builtin, but now we fail
22 because we couldn't find the module.
25 - Integration of gcov into the build. Currently libkmod is at ~70%
26 covered and tools at ~50% by tests in the testsuite. Utility
27 functions and structures in shared have more than 90% of coverage.
28 - Upload build to coverity
30 - Improvements to testsuite:
31 - Fix parsing return codes of init_module() calls
32 - Add tests for utility functions in shared/
33 - Add tests for kmod_module_remove_module()
34 - Add playground, in which our own modules are compiled
35 - Port all tests to use modules from module-playground instead of
36 copying prebuilt modules to the repository
37 - Properly handle binaries that exit with no output
38 - Besides comparing the output of commands, allow to copy to
45 - Fix missing CLOEXEC in library
46 - Fix error message while opening kmod's index
49 - Add kmod(8) man page
50 - Allow to build with libc's without be32toh()
51 - Move code around separating common code and data structures into a
52 shared directory. This allows to share more code between library and
53 tools, making the binary size of tools smaller.
54 - Clarify tools vs library licenses
55 - static-nodes: when writing in tmpfiles format, indicate that
56 creation of static nodes should only happen at boot. This is used and
57 required by systemd-217+.
59 - Improvements to testsuite:
60 - Add tests for newly created shared/ code
61 - Improve how tests are declared so there's less boilerplate code for
68 - Fix leaks in error paths
69 - Fix use-after-free in hash implementation causing a wrong index to be
70 generated by depmod with out-of-tree modules
73 - Calling depmod with modules creating a dependency loop will now make
74 depmod return an error and not update the indexes. This is to protect
75 the current index not being overridden by another index that may cause
76 a boot failure, depending on the buggy module. It's a necessary
77 change in behavior regarding previous kmod releases and
78 module-init-tools. The error message was also improved to output
79 the modules that caused the dependency cycle.
81 - Improvements to testsuite:
82 - Fix and improve expected-fail test
83 - Add tests for hashmap implementation
89 - Fix matching a "." in kernel cmdline, making garbage in the command
90 line be parsed as kmod options
91 - Fix man pages to clarify we don't fallback to parsing modules.dep
92 but instead we depend on modules.dep.bin (generated by depmod) to
94 - Fix ELF parsing on 32 bit systems assigning the wrong class.
95 - Fix partial matches of search directives in depmod. Previously having
96 a line in depmod.conf such as "search foo foobar built-in" would cause
97 unpretictable results because foo is a partial match of foobar as well.
98 - Fix unaligned access in modinfo when getting the signature from a
100 - Make sure softdeps are treated as optional dependencies
103 - Accept special files given to "-C" switch in modprobe. This way it's
104 possible to skip system configuration with "modprobe -C /dev/null"
105 - Do not require xsltproc on released tarballs
106 - Don't use Werror anymore
107 - Add experimental python bindings, merged from python-kmod repository
108 (https://github.com/agrover/python-kmod)
109 - Parse softdeps exported by the kernel as
110 /lib/modules/`uname -r`/modules.softdep
112 - Improvements to testsuite:
113 - Check the list of loaded modules after a test
119 - Fix usage of readdir_r()
120 - Add some missing checks for memory allocation errors
123 - Remove option from libkmod to allow waiting on module removal if
124 the module is being used. It's dangerous since it can block the
126 - Improve compatibility with musl libc
127 - Add fallback implementation for compilers without _Static_assert(),
129 - Minor optimizations to the hash table
130 - Make depmod warn if a module has incorrect devname specification
131 - Use cleanup attribute
137 - kmod static-nodes doesn't fail if modules.devname isn't available
138 - Fix getting boolean parameter from kernel cmdline in case the value
140 - Fix some mkdir_p() corner cases (used in testsuite and static-nodes)
143 - kmod static-nodes creates parent directories if given a -o option
144 - kmod binary statically links to libkmod - if distro is only interested
145 in the kmod tool (for example in an initrd) it can refrain from
146 installing the library
147 - Add shell completion for kmod tool
153 - Fix some format strings
154 - Protect against NULL being passed around to index
155 - Avoid calling syscall() with -1 when finit_module() is not available,
156 since this doesn't always work
157 - Fix not being able to remove alias due to checking the module's
159 - Minor fixes and refactors
162 - Improve libkmod documentation, particularly on how flags are dealt
164 - Remove ability to build a static libkmod
165 - Add static-nodes command to kmod that parses modules.devname
166 generating output in useful formats
172 - Add the long option --symbol-prefix option to depmod (it was absent)
174 - Don't abort if there's a bogus line in configuration file like "alias
175 psmouse off". Some distros are carrying this since the days of
179 - Add support for finit_module(2). If the module is load straight from
180 the disk and without compression we use finit_module() syscall when
181 available, falling back to init_module() otherwise
182 - kmod_module_get_info() also returns the signature if the module is
183 signed and modinfo uses it
184 - Use secure_getenv if available
185 - rmmod understands builtin modules, just like modprobe does
186 - Improve compatibility with musl-libc
187 - Test cases exit with success when receiving a signal if they are
194 - Fix removing vermagic from module when told to force load a module
195 - Fix removing __versions section when told to force load a module: we
196 need to mangle the section header, not the section.
197 - modinfo no longer fails while loading a module from file when path
198 contains ".ko" substring
203 - Improvements to testsuite:
204 - Fix testsuite defining symbols twice on 32 bit systems
205 - Allow to check generated files against correct ones
208 - libkmod now keeps a file opened after the first call to
209 kmod_module_get_{info,versions,symbols,dependency_symbols}. This
210 reduces signficantly the amount of time depmod tool takes to
211 execute. Particularly if compressed modules are used.
212 - Remove --with-rootprefix from build system. It was not a great idea
213 after all and should not be use since it causes more harm then
215 - Hide --wait option on rmmod. This feature is being targeted for
216 removal from kernel. rmmod still accepts this option, but it's hidden
217 now: man page and usage() say nothing about it and if it's used,
218 user will get a 10s sleep. This way we can check and help if anyone
219 is using this feature.
220 - Refactor message logging on all tools, giving proper prefix, routing
221 everything to syslog when asked for, etc.
224 - Fix parsing of modules.order when using compressed modules
225 - Usage messages go to stdout instead of stderr
226 - Fix memory leak in hash implementation
232 - Read coresize from /sys if supported
234 - Add flag to kmod_module_probe_insert() to apply blacklisting during
235 probe only if mod is an alias. Now modprobe uses this flag by default.
236 This is needed to fix a change in behavior regarding module-init-tools
237 and ultimately makes us loading a blacklisted module.
239 - Better formatting in man pages
241 - Add option to disable building man pages at build time
243 - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries
245 - Re-licensing testsuite as LGPL
250 - Improvements to the testsuite:
251 - Check for correct handling of softdep loops
252 - Check for correct handling of install command loops
255 - Fix build with compilers that don't support --gc-sections
256 - Handle errors when dealing with gzipped modules
257 - depmod now handles errors while writing indices, so it doesn't end up
258 with a corrupted index without telling the user
263 - No new features, small bug fixes only.
264 - Fix a bug in "modprobe -c" output: be compatible with
267 - Give a useful error message when init_module fails due to bad
268 parameter or unknown symbols
275 - Re-order dirs for configuration files to match the change in systemd and
276 udev: now the priority is:
281 - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not
282 allowing the user to set his preferences.
285 - Return same error codes of module-init-tools when removing modules
287 - Fix builtin output in "--show-depends" when target kernel is not the
288 same of the running kernel
289 - 'modprobe -r' always look at all command line arguments
290 - Fix '-q' usage in modprobe
295 - New API in libkmod:
296 - kmod_module_apply_filter(): a generic function to apply filters in a
297 list of modules. This deprecates the use of
298 kmod_module_get_filtered_blacklist()
300 - More tests in testsuite
302 - Add compatibility with uClibc again
304 - Lookup modules.builtin.bin to decide if a module is built in kernel
306 - Downgrade some log messages so we don't annoy people with useless messages
309 - Flag --ignore-loaded was not being properly handled
310 - Infinite loop with softdeps
311 - Infinite loop with dumb user configuration with install commands
312 - Fix leak in index when there's a partial match
314 - Move repository and tarballs to kernel.org
319 - Break libkmod's API to insert a module like modprobe does. It now accepts
320 extra an extra argument to print its action and acceptable flags were
323 - Share more code between modprobe and libkmod: using the new version of
324 kmod_module_probe_insert_module() it's possible to share a great amount of
325 code between modprobe and libkmod
327 - modprobe no longer works with paths: it only accepts module names and/or
330 - testsuite was added to repository, allowing automated tests to be run and
331 easing the way bugs are reproduced.
333 - modprobe: when dumping configuration ('-c' option) separate config
334 and indexes by adding a commented line between them.
336 - Fix bugs wrt normalizing aliases and module names
338 - Fix bug wrt inserting an alias that resolves to multiple modules: we should
339 not stop on the first error, but rather continue to try loading other
342 - Fix unaligned memory access in hash function, causing depmod to output wrong
345 - Fix man page build and install: now they are only installed if tools are
351 - New APIs in libkmod to:
352 - Get configuration lists: blacklists, install commands, remove
353 commands, aliases, options and softdeps
356 - Several bugs fixed in libkmod, modprobe, depmod and modinfo
358 - API documentation: if configure with run with --enable-gtk-doc, the API doc
359 will be generated by make. Gtk-doc is required for that.
361 - Man pages are built, which replace man pages from module-init-tools
363 - 'include' and 'config' options in *.conf files were deprecated
365 - configure is not run by autogen.sh. Instead, a common set of options is
366 printed. If you are hacking on kmod, consider using bootstrap-configure
369 - 'modprobe -c' works as expected now. As opposed to module-init-tools, it
370 dumps the parsed configuration, not only the file contents.
375 - New APIs in libkmod to:
376 - Get symbols from module, parsing the ELF section
377 - Get dependency symbols
378 - Check if resources are still valid or if libkmod must be reloaded
379 - Insert module like modprobe, checking (soft-)dependencies, commands,
380 blacklist. It can run commands by itself and to call a callback
383 - Support to load modules compressed with xz
385 - Tools are now bundled together in a single tool called kmod. It can be
386 called using symlinks with the same names as tools from module-init-tools.
387 E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a
388 1:1 replacement of module-init-tools.
390 - The only missing tool, depmod, was added to kmod together with the necessary
393 - If a program using libkmod runs for a long time, as for example udev, it must
394 check if it doesn't have to re-load libkmod. A new helper function was added
395 in libkmod to check if context is still valid and udev is already using it.
397 - An 'unaligned access' bug was fixed. So those architecture that does not
398 handle unaligned access can use kmod, too.
403 Some bugs fixed: the worst of them was with an infinite loop when an alias
404 matched more than one module.
406 - New APIs in libkmod to:
407 - Get soft dependencies
408 - Get info from module files parsing ELF
409 - Get modversions from files parsing ELF
411 - Support to load gzipped kernel modules: kmod can be compiled with support to
412 gzipped modules by giving the --enable-zlib flag
414 - Support to forcefully load modules, both vermagic and modversion
416 - Support to force and nowait removal flags
418 - Configuration files are parsed in the same order as modprobe: files are
419 sorted alphabetically (independently of their dir) and files with the same
420 name obey a precedence order
422 - New tool: kmod-modinfo
424 - kmod-modprobe gained several features to be a 1:1 replacement for modprobe.
425 The only missing things are the options '--showconfig' and '-t / -l'. These
426 last ones have been deprecated long ago and they will be removed from
427 modprobe. A lot of effort has been put on kmod-modprobe to ensure it
428 maintains compabitility with modprobe.
430 - linux-modules@vger.kernel.org became the official mailing list for kmod
435 First version of kmod and its library, libkmod.
437 In the libkmod it's currently possible to:
438 - List modules currently loaded
439 - Get information about loaded modules such as initstate, refcount,
440 holders, sections, address and size
441 - Lookup modules by alias, module name or path
442 - Insert modules: options from configuration and extra options can be
443 passed, but flags are not implemented, yet
445 - Filter list of modules using blacklist
446 - For each module, get the its list of options and install/remove
448 - Indexes can be loaded on startup to speedup lookups later
450 Tools provided with the same set of options as in module-init-tools:
454 - kmod-modprobe, with some functionality still missing (use of softdep,
455 dump configuration, show modversions)
