1 | kmod 31 |
2 | ======= | |
3 | ||
4 | - Improvements | |
5 | ||
6 | - Allow passing a path to modprobe so the module is loaded from | |
7 | anywhere from the filesystem, but still handling the module | |
8 | dependencies recorded in the indexes. This is mostly intended for kernel | |
9 | developers to speedup testing their kernel modules without having to load the | |
10 | dependencies manually or override the module in /usr/lib/modules/. | |
11 | Now it's possible to do: | |
12 | ||
13 | # modprobe ./drivers/gpu/drm/i915/i915.ko | |
14 | ||
15 | As long as the dependencies didn't change, this should do the right thing | |
16 | ||
17 | - Use in-kernel decompression if available. This will check the runtime support | |
18 | in the kernel for decompressing modules and use it through finit_module(). | |
19 | Previously kmod would fallback to the older init_module() when using | |
20 | compressed modules since there wasn't a way to instruct the kernel to | |
21 | uncompress it on load or check if the kernel supported it or not. | |
22 | This requires a recent kernel (>= 6.4) to have that support and | |
23 | in-kernel decompression properly working in the kernel. | |
24 | ||
25 | - Make modprobe fallback to syslog when stderr is not available, as was | |
26 | documented in the man page, but not implemented | |
27 | ||
28 | - Better explaing `modprobe -r` and how it differentiates from rmmod | |
29 | ||
30 | - depmod learned a `-o <dir>` option to allow using a separate output | |
31 | directory. With this, it's possible to split the output files from | |
32 | the ones used as input from the kernel build system | |
33 | ||
34 | - Add compat with glibc >= 2.32.9000 that dropped __xstat | |
35 | ||
36 | - Improve testsuite to stop skipping tests when sysconfdir is something | |
37 | other than /etc | |
38 | ||
39 | - Build system improvements and updates | |
40 | ||
41 | - Change a few return codes from -ENOENT to -ENODATA to avoid confusing output | |
42 | in depmod when the module itself lacks a particular ELF section due to e.g. | |
43 | CONFIG_MODVERSIONS=n in the kernel. | |
44 | ||
45 | ||
46 | - Bug Fixes | |
47 | ||
48 | - Fix testsuite using uninitialized memory when testing module removal | |
49 | with --wait | |
50 | ||
51 | - Fix testsuite not correctly overriding the stat syscall on 32-bit | |
52 | platforms. For most architectures this was harmless, but for MIPS it | |
53 | was causing some tests to fail. | |
54 | ||
55 | - Fix handling unknown signature algorithm | |
56 | ||
57 | - Fix linking with a static liblzma, libzstd or zlib | |
58 | ||
59 | - Fix memory leak when removing module holders | |
60 | ||
61 | - Fix out-of-bounds access when using very long paths as argument to rmmod | |
62 | ||
63 | - Fix warnings reported by UBSan | |

65 | kmod 30 |
66 | ======= | |
67 | ||
68 | - Improvements | |
69 | - Stop adding duplicate information on modules.builtin.alias.bin, just use | |
70 | the modules.builtin.bin index | |
71 | ||
72 | - Speedup depmod, particularly under qemu with emulated arch, by | |
73 | avoiding a lot of open/read/close of modules.alias.bin. On an | |
74 | emulated ARM rootfs, depmod with only 2 modules was taking ~32s | |
75 | vs ~0.07s now. | |
76 | ||
77 | - Add kmod_module_new_from_name_lookup() which allows doing a lookup by | |
78 | module name, without considering the aliases. Other than that search | |
79 | order is similar to kmod_module_new_from_lookup(). | |
80 | ||
81 | - modinfo learned the --modname option to explicitely show information | |
82 | about the module, even if there is an alias with the same name. This | |
83 | allows showing information about e.g. kernel/lib/crc32.ko, even if | |
84 | kernel also exports a crc32 alias in modules.alias: | |
85 | ||
86 | alias crc32 crc32_pclmul | |
87 | alias crc32 crc32_generic | |
88 | ||
89 | Same behavior will be used to other modules and to aliases provided | |
90 | by user/distro. | |
91 | ||
92 | - depmod.conf learned a new "excludedir" directive so distro/user can | |
93 | configure more directories to be excluded from its search, besides | |
94 | the hardcoded values "build" and "source". | |
95 | ||
96 | - Better group modprobe options on help output under "Management, Query and General". | |
97 | ||
98 | - modprobe learned a --wait <MSEC> option to be used together with -r | |
99 | when removing a module. This allows modprobe to keep trying the | |
100 | removal if it fails because the module is still in use. An exponential backoff | |
101 | time is used for further retries. | |
102 | ||
103 | The wait behavior provided by the kernel when not passing O_NONBLOCK | |
104 | to delete_module() was removed in v3.13 due to not be used and the | |
105 | consequences of having to support it in the kernel. However there may | |
106 | be some users, particularly on testsuites for individual susbsystems, that | |
107 | would want that. So provide a userspace implementation inside modprobe for | |
108 | such users. "rmmod" doesn't have a --wait as it remains a bare minimal over | |
109 | the API provided by the kernel. In future the --wait behavior can be added | |
110 | to libkmod for testsuites not exec'ing modprobe for module removal. | |
111 | ||
112 | - kmod_module_remove_module() learned a new flag to silence output when | |
113 | caller wants to handle them - this is particularly important for the | |
114 | --wait flag to modprobe, as it's not desired to keep seeing error messages | |
115 | while waiting for the module to be unused. | |
116 | ||
117 | - Add SM3 hash algo support to modinfo output, as already available in the kernel. | |
118 | ||
119 | - Bug Fixes | |
120 | - Fix modinfo output when showing information for a .ko module when running | |
121 | on a kernel that has that module as builtin. | |
122 | ||
123 | - Fix kmod_module_new_from_lookup() returning > 0 rather than 0 | |
124 | when it matches an alias. | |
125 | ||
126 | - Fix modinfo segfault when module doesn't exist. | |
127 | ||
128 | - Add missing function in the html documentation: kmod_get_dirname(). | |
129 | ||
130 | - Fix modprobe incorrectly handling number of arguments when prepending values from | |
131 | MODPROBE_OPTIONS environment variable. | |
132 | ||
133 | - Fix modprobe -r --remove-dependencies and since "dependencies" was a | |
134 | misnomer, add the preferred argument option: "--remove-holders". This | |
135 | is the same name used by the kernel. It allows users to also remove | |
136 | other modules holding the one that is being removed. | |
137 | ||
138 | - Fix off-by-one in max module name length in depmod. | |
139 | ||
140 | - Infra/internal | |
141 | - Start some changes in the out-of-tree test modules in kmod so they are useful | |
142 | for being really inserted in the kernel rather than relying on kmod's mock | |
143 | interface. This helps manual testing and may be used to exercise to test | |
144 | changes in the kernel. | |

146 | kmod 29 |
147 | ======= | |
148 | ||
149 | - Improvements | |
150 | - Add support to use /usr/local as a place for configuration files. This makes it easier | |
151 | to install locally without overriding distro files. | |
152 | ||
153 | - Bug fixes | |
154 | - Fix `modinfo -F` when module is builtin: when we asked by a specific field from modinfo, | |
155 | it was not working correctly if the module was builtin | |
156 | ||
157 | - Documentation fixes on precedence order of /etc and /run: the correct order is | |
158 | /etc/modprobe.d, /run/modprobe.d, /lib/modprobe.d | |
159 | ||
160 | - Fix the priority order that we use for searching configuration files. The | |
161 | correct one is /etc, /run, /usr/local/lib, /lib, for both modprobe.d | |
162 | and depmo.d | |
163 | ||
164 | - Fix kernel command line parsing when there are quotes present. Grub | |
165 | mangles the command line and changes it from 'module.option="val with | |
166 | spaces"' to '"module.option=val with spaces"'. Although this is weird | |
167 | behavior and grub could have been fixed, the kernel understands it | |
168 | correctly for builtin modules. So change libkmod to also parse it | |
169 | correctly. This also brings another hidden behavior from the kernel: | |
170 | newline in the kernel command line is also allowed and can be used to | |
171 | separate options. | |
172 | ||
173 | - Fix a memory leak, overflow and double free on error path | |
174 | ||
175 | - Fix documentation for return value from kmod_module_get_info(): we | |
176 | return the number of entries we added to the list | |
177 | ||
178 | - Fix output of modules.builtin.alias.bin index: we were writing an empty file due to | |
179 | the misuse of kmod_module_get_info() | |
180 | ||
181 | - Infra/internal | |
182 | - Retire integration with semaphoreci | |
183 | ||
184 | - Declare the github mirror also as an official upstream source: now besides accepting | |
185 | patches via mailing list, PRs on github are also acceptable | |
186 | ||
187 | - Misc improvements to testsuite, so we can use it reliably regardless | |
188 | of the configuration used: now tests will skip if we don't have the | |
189 | build dependencies) | |

191 | kmod 28 |
192 | ======= | |
193 | ||
194 | - Improvements | |
195 | - Add Zstandard to the supported compression formats using libzstd | |
196 | (pass --with-zstd to configure) | |
197 | ||
198 | - Bug fixes | |
199 | - Ignore ill-formed kernel command line, e.g. with "ivrs_acpihid[00:14.5]=AMD0020:0" | |
200 | option in it | |
201 | - Fix some memory leaks | |
202 | - Fix 0-length builtin.alias.bin: it needs at least the index header | |
203 | ||

204 | kmod 27 |
205 | ======= | |
206 | ||
207 | - Improvements | |
208 | - Link to libcrypto rather than requiring openssl | |
209 | ||
210 | - Print a better error message when kernel doesn't support module unload | |
211 | ||
212 | - Use PKCS#7 instead of CMS for parsing module signature to be | |
213 | compatible with LibreSSL and OpenSSL < 1.1.0 | |
214 | ||
215 | - Teach modinfo to parse modules.builtin.modinfo. When using Linux kernel | |
216 | >= v5.2-rc1 it's possible to get module information from this new file. Now | |
217 | modinfo is able to show it instead of an error message that the module is | |
218 | built-in: | |
219 | ||
220 | Before: | |
221 | $ modinfo ext4 | |
222 | modinfo: ERROR: Module ext4 not found. | |
223 | ||
224 | After: | |
225 | $ modinfo ext4 | |
226 | name: ext4 | |

238 | - Bug fixes | |
239 | - Do not link python bindings with libpython to be compatible with | |
240 | python3.8 | |
241 | ||
242 | - Fix module removal with `modprobe -r` when a dependency is built-in. | |
243 | Now it properly ignores them and proceed with removal of other | |
244 | dependencies | |
245 | ||
246 | - Fix propagation of return code from install/remove commands to the | |
247 | the probe function. The return values of kmod_module_probe_insert_module() | |
248 | have very specific meanings, do not confuse the caller by return codes | |
249 | from system() | |
250 | ||
251 | - Fix softdep config parsing leading to buffer overflow | |

253 | kmod 26 |
254 | ======= | |
255 | ||
256 | - Improvements | |
257 | - Add more error-checking in library functions and remove warnings on newer | |
258 | toolchains | |
259 | ||
260 | - Depmod now handles parallel invoctions better by protecting the temporary | |
261 | files being used | |
262 | ||
263 | - Improvements to testsuite and added tests to check the our behavior | |
264 | regardless of the features enabled in the kernel, or libraries we link to | |
265 | ||
266 | - Teach the --show-exports option to modprobe. This works similarly to | |
267 | --show-modversions, but it reports the exported symbols from that module. | |
268 | Under the hood this reads the .symtab and .strtab section rather than | |
269 | __versions so it shows useful data even if kernel is configured without | |
270 | modversions (CONFIG_MODVERSIONS) | |
271 | ||
272 | - Teach pkcs7 parsing to modinfo by using openssl. This allows modinfo to | |
273 | correctly parse the signature appended to a module by the kernel build | |
274 | system when configured with CONFIG_MODULE_SIG_ALL, or when externally | |
275 | signed by the distro. Traditionally modules were signed and a struct | |
276 | was appended together with the signature to the end of the module. | |
277 | This has changed on the kernel for pkcs#7 and now the structure isn't | |
278 | filled out with useful information. So we have to parse the signature | |
279 | block in order to return useful data to the user. | |
280 | ||
281 | If kmod is linked with openssl we parse the signature and return the | |
282 | fields as we do for other signatures. An example of the relevant part | |
283 | on the output of modinfo is below: | |
284 | ||
285 | Before: | |
286 | sig_id: PKCS#7 | |
287 | signer: | |
288 | sig_key: | |
289 | sig_hashalgo: md4 | |
290 | After: | |
291 | sig_id: PKCS#7 | |
292 | signer: Fedora kernel signing key | |
293 | sig_key: 51:C4:0C:6D:7E:A5:6C:D8:8F:B4:3A:DF:91:78:4F:18:BC:D5:E4:C5 | |
294 | sig_hashalgo: sha256 | |
295 | ||
296 | If kmod is not linked to openssl we just start printing "unknonwn" in the | |
297 | sig_hashalgo field rather than the bogus value. | |

300 | kmod 25 |
301 | ======= | |
302 | ||
303 | - Improvements | |
304 | - Add module signature to modinfo output | |
305 | ||
306 | - Add support for external directories in depmod: now there's a new | |
307 | "external" keyword parsed by depmod when calculating the dependencies. | |
308 | It allows to add modules to other directories which are not relative | |
309 | to where the modules are commonly installed. This results in | |
310 | modules.dep and friends now understanding absolute paths rather than | |
311 | relative paths only. For more information see depmod.d(1). | |
312 | ||
313 | - Add support for CONFIG_MODULE_REL_CRCS | |
314 | ||
315 | - Add missing documentation references in man pages | |
316 | ||
317 | - Handle the case in which module has a .TOC symbol already while | |
318 | calculating dependencies | |
319 | ||
320 | - Improve testsuite and allow to use mkosi to run testsuite in different | |
321 | distros | |
322 | ||

323 | kmod 24 |
324 | ======= | |
325 | ||
326 | - Improvements: | |
327 | - Add more information on dependency loop | |
328 | ||
329 | - Sanitize use of strcpy and allow to grow from small strings on stack | |
330 | (common case) to bigger strings on heap when needed | |
331 | ||
332 | - Bug fixes | |
333 | - Fix wrong dependency loops being reported by depmod | |
334 | ||
335 | - Fix crashes when reporting dependency loops | |
336 | ||
337 | - Fix parsing kernel command line containing quotes | |
338 | ||
339 | - Fix leaks on error paths | |

341 | kmod 23 |
342 | ======= | |
343 | ||
344 | - Improvements: | |
345 | - Don't add comment to modules.devname if it would otherwise be empty | |
346 | to play nice with tools detecting empty files | |
347 | ||
348 | - Allow building with BSD sed, that doesn't have -E flag | |
349 | ||
350 | - Ignore .TOC. symbols in depmod parsing as it's for PPC64 the | |
351 | equivalent of _GLOBAL_OFFSET_TABLE_ | |
352 | ||
353 | - Teach modinfo about PKCS#7 module signatures: it doesn't add any | |
354 | other info besides telling the user the module is signed since | |
355 | kernel doesn't add other info on the module section | |
356 | ||
357 | - Bug fixes | |
358 | ||
359 | - Fix -s and -p compat options to insmod triggering force flag | |
360 | ||
361 | - Fix long lines from /proc/modules not being handled correctly by | |
362 | kmod_module_new_from_loaded() and kmod_module_get_size() and several | |
363 | other library functions that use them | |
364 | ||
365 | - Fix crash on modinfo while checking for available signature of | |
366 | unknown type | |
367 | ||
368 | - Fix documentation generation with gtk-doc | |
369 | ||
42f32b8a LDM |
370 | kmod 22 |
371 | ======= | |
372 | ||
373 | - Tools: | |
374 | - Change defaul log level for tools to WARNING rather than ERROR and update | |
375 | some log levels for current messages | |
376 | ||
377 | - depmod doesn't fallback to uname if a bad version is passed in the command | |
378 | line anymore. We just exit with an error. | |
379 | ||
380 | - insmod was taught the -f flag, just like in modprobe. It was previously | |
381 | silently ignoring it. | |
382 | ||
383 | - libkmod | |
384 | - New kmod_get_dirname() API to get the module directory set in the | |
385 | context | |
386 | ||
387 | - Bug fixes: | |
388 | - Fix return code in error path of kmod_module_insert_module(). We were | |
389 | previously returning ENOSYS rather than ENOENT. | |
390 | ||
2bfcd7ef LDM |
391 | kmod 21 |
392 | ======= | |
393 | ||
394 | - New features: | |
395 | - kmod tool started to learn the "insert" and "remove" commands that | |
396 | are the simplified versions of the older modprobe tool. These | |
397 | commands are still work in progress so they are hidden behind a | |
398 | --enable-experimental flag during build. It should not be enabled | |
399 | unless you know what you're doing. | |
400 | - kmod tool now prints the relevant configuration options it was built | |
401 | with when the "--version" argument is passed. This helps to mitigate | |
402 | problems for example when the user is trying to load a compressed | |
403 | module but kmod was built without support for the compression method. | |
404 | ||
405 | - Improvements to testsuite: | |
406 | - Cache built modules so it is easier to run "make check" on build | |
407 | servers by distro maintainers. If kmod is configured with | |
408 | --disable-test-modules the modules from cache will be used by | |
409 | "make check". No changes to the tests are needed and all of them | |
410 | can run fine. | |
411 | ||
d9c71758 LDM |
412 | kmod 20 |
413 | ======= | |
414 | - Bug fixes: | |
415 | - Handle bogus values from ELF, making sure they don't overflow while | |
416 | parsing the file | |
417 | - Fix leak in depmod when -b flag is passed multiple times | |
418 | - Multiple minor fixes from static analysis by coverity and | |
419 | clang-analyze | |
420 | - Fix race between loading modules and checking if it's loaded in the | |
421 | kernel | |
422 | ||
423 | - New features: | |
424 | - There's a change in behavior regarding builtin modules: we now only | |
425 | consider as builtin those that are present in modules.builtin index. | |
426 | Previously we were also checking the presence of | |
427 | /sys/module/<module-name>, but this is racy and only modules that | |
428 | contain parameters are the ones creating a directory in sysfs. | |
429 | ||
430 | Now some commands will start to fail, e.g. "modprobe vt". Since vt | |
431 | can't be compiled as a module it's not present in modules.builtin | |
432 | index. Previously we would report at as builtin, but now we fail | |
433 | because we couldn't find the module. | |
434 | ||
435 | - Improvements: | |
436 | - Integration of gcov into the build. Currently libkmod is at ~70% | |
437 | covered and tools at ~50% by tests in the testsuite. Utility | |
438 | functions and structures in shared have more than 90% of coverage. | |
439 | - Upload build to coverity | |
440 | ||
441 | - Improvements to testsuite: | |
442 | - Fix parsing return codes of init_module() calls | |
443 | - Add tests for utility functions in shared/ | |
444 | - Add tests for kmod_module_remove_module() | |
445 | - Add playground, in which our own modules are compiled | |
446 | - Port all tests to use modules from module-playground instead of | |
447 | copying prebuilt modules to the repository | |
448 | - Properly handle binaries that exit with no output | |
449 | - Besides comparing the output of commands, allow to copy to | |
450 | stdout/stderr | |

452 | kmod 19 |
453 | ======= | |
454 | ||
455 | - Bug fixes: | |
456 | - Fix missing CLOEXEC in library | |
457 | - Fix error message while opening kmod's index | |
458 | ||
459 | - New features: | |
460 | - Add kmod(8) man page | |
461 | - Allow to build with libc's without be32toh() | |
462 | - Move code around separating common code and data structures into a | |
463 | shared directory. This allows to share more code between library and | |
3b058610 | 464 | tools, making the binary size of tools smaller. |
f9e2167b | 465 | - Clarify tools vs library licenses |
3b058610 | 466 | - static-nodes: when writing in tmpfiles format, indicate that |
f9e2167b LDM |
467 | creation of static nodes should only happen at boot. This is used and |
468 | required by systemd-217+. | |
469 | ||
470 | - Improvements to testsuite: | |
471 | - Add tests for newly created shared/ code | |
472 | - Improve how tests are declared so there's less boilerplate code for | |
473 | each test. | |

481 | generated by depmod with out-of-tree modules | |
482 | ||
483 | - New features: | |
484 | - Calling depmod with modules creating a dependency loop will now make | |
485 | depmod return an error and not update the indexes. This is to protect | |
486 | the current index not being overridden by another index that may cause | |
487 | a boot failure, depending on the buggy module. It's a necessary | |
488 | change in behavior regarding previous kmod releases and | |
489 | module-init-tools. The error message was also improved to output | |
490 | the modules that caused the dependency cycle. | |
491 | ||
492 | - Improvements to testsuite: | |
493 | - Fix and improve expected-fail test | |
494 | - Add tests for hashmap implementation | |

496 | kmod 17 |
497 | ======= | |
498 | ||
499 | - Bug fixes: | |
500 | - Fix matching a "." in kernel cmdline, making garbage in the command | |
501 | line be parsed as kmod options | |
502 | - Fix man pages to clarify we don't fallback to parsing modules.dep | |
503 | but instead we depend on modules.dep.bin (generated by depmod) to | |
504 | be present | |
505 | - Fix ELF parsing on 32 bit systems assigning the wrong class. | |
506 | - Fix partial matches of search directives in depmod. Previously having | |
507 | a line in depmod.conf such as "search foo foobar built-in" would cause | |
508 | unpretictable results because foo is a partial match of foobar as well. | |
509 | - Fix unaligned access in modinfo when getting the signature from a | |
510 | module | |
511 | - Make sure softdeps are treated as optional dependencies | |
512 | ||
513 | - New features: | |
514 | - Accept special files given to "-C" switch in modprobe. This way it's | |
515 | possible to skip system configuration with "modprobe -C /dev/null" | |
516 | - Do not require xsltproc on released tarballs | |
517 | - Don't use Werror anymore | |
518 | - Add experimental python bindings, merged from python-kmod repository | |
519 | (https://github.com/agrover/python-kmod) | |
520 | - Parse softdeps exported by the kernel as | |
521 | /lib/modules/`uname -r`/modules.softdep | |
522 | ||
523 | - Improvements to testsuite: | |
524 | - Check the list of loaded modules after a test | |

36c4bb92 | 531 | - Add some missing checks for memory allocation errors |
8f67ab53 | 532 | |
7ab88044 LDM |
533 | - New features: |
534 | - Remove option from libkmod to allow waiting on module removal if | |
535 | the module is being used. It's dangerous since it can block the | |
536 | caller indefinitely. | |
8f67ab53 LDM |
537 | - Improve compatibility with musl libc |
538 | - Add fallback implementation for compilers without _Static_assert(), | |
539 | e.g. gcc < 4.6 | |
540 | - Minor optimizations to the hash table | |
541 | - Make depmod warn if a module has incorrect devname specification | |
36c4bb92 | 542 | - Use cleanup attribute |

18811d22 LDM |
549 | - Fix getting boolean parameter from kernel cmdline in case the value |
550 | is omitted | |
551 | - Fix some mkdir_p() corner cases (used in testsuite and static-nodes) | |
b3e19ce9 LDM |
552 | |
553 | - New features: | |
554 | - kmod static-nodes creates parent directories if given a -o option | |
18811d22 LDM |
555 | - kmod binary statically links to libkmod - if distro is only interested |
556 | in the kmod tool (for example in an initrd) it can refrain from | |
557 | installing the library | |
558 | - Add shell completion for kmod tool | |

563 | - Bug fixes: | |
564 | - Fix some format strings | |
565 | - Protect against NULL being passed around to index | |
566 | - Avoid calling syscall() with -1 when finit_module() is not available, | |
567 | since this doesn't always work | |
568 | - Fix not being able to remove alias due to checking the module's | |
569 | refcount | |
570 | - Minor fixes and refactors | |
571 | ||
572 | - New features: | |
573 | - Improve libkmod documentation, particularly on how flags are dealt | |
574 | with. | |
575 | - Remove ability to build a static libkmod | |
576 | - Add static-nodes command to kmod that parses modules.devname | |
577 | generating output in useful formats | |

580 | ======= | |

582 | - Bug fixes: | |
583 | - Add the long option --symbol-prefix option to depmod (it was absent) | |
584 | and fix its behavior | |
585 | - Don't abort if there's a bogus line in configuration file like "alias | |
586 | psmouse off". Some distros are carrying this since the days of | |
587 | modutils | |
588 | ||
589 | - New features: | |
590 | - Add support for finit_module(2). If the module is load straight from | |
591 | the disk and without compression we use finit_module() syscall when | |
592 | available, falling back to init_module() otherwise | |
593 | - kmod_module_get_info() also returns the signature if the module is | |
594 | signed and modinfo uses it | |
595 | - Use secure_getenv if available | |
596 | - rmmod understands builtin modules, just like modprobe does | |
597 | - Improve compatibility with musl-libc | |
598 | - Test cases exit with success when receiving a signal if they are | |
599 | xfail tests | |

602 | ======= | |
603 | ||
604 | - Bug fixes: | |
605 | - Fix removing vermagic from module when told to force load a module | |
606 | - Fix removing __versions section when told to force load a module: we | |
607 | need to mangle the section header, not the section. | |
608 | - modinfo no longer fails while loading a module from file when path | |
609 | contains ".ko" substring | |

611 | kmod 11 |
612 | ======= | |
613 | ||
614 | - Improvements to testsuite: | |
615 | - Fix testsuite defining symbols twice on 32 bit systems | |
616 | - Allow to check generated files against correct ones | |
617 | ||
618 | - New features: | |
619 | - libkmod now keeps a file opened after the first call to | |
620 | kmod_module_get_{info,versions,symbols,dependency_symbols}. This | |
c7243325 | 621 | reduces significantly the amount of time depmod tool takes to |
c599606f LDM |
622 | execute. Particularly if compressed modules are used. |
623 | - Remove --with-rootprefix from build system. It was not a great idea | |
624 | after all and should not be use since it causes more harm then | |
625 | benefits. | |
626 | - Hide --wait option on rmmod. This feature is being targeted for | |
627 | removal from kernel. rmmod still accepts this option, but it's hidden | |
7ab88044 | 628 | now: man page and usage() say nothing about it and if it's used, |
c599606f LDM |
629 | user will get a 10s sleep. This way we can check and help if anyone |
630 | is using this feature. | |
631 | - Refactor message logging on all tools, giving proper prefix, routing | |
632 | everything to syslog when asked for, etc. | |
633 | ||
634 | - Bug fixes: | |
635 | - Fix parsing of modules.order when using compressed modules | |
636 | - Usage messages go to stdout instead of stderr | |
637 | - Fix memory leak in hash implementation | |

644 | ||
a7fbae03 JE |
645 | - Add flag to kmod_module_probe_insert() to apply blacklisting during |
646 | probe only if mod is an alias. Now modprobe uses this flag by default. | |
40758602 | 647 | This is needed to fix a change in behavior regarding module-init-tools |
a7fbae03 | 648 | and ultimately makes us loading a blacklisted module. |
40758602 LDM |
649 | |
650 | - Better formatting in man pages | |

664 | ||
665 | - Bug fixes: | |
666 | - Fix build with compilers that don't support --gc-sections | |
a7fbae03 JE |
667 | - Handle errors when dealing with gzipped modules |
668 | - depmod now handles errors while writing indices, so it doesn't end up | |

703 | kmod 6 |
704 | ====== | |
705 | ||
706 | - New API in libkmod: | |
707 | - kmod_module_apply_filter(): a generic function to apply filters in a | |
708 | list of modules. This deprecates the use of | |
709 | kmod_module_get_filtered_blacklist() | |
710 | ||
711 | - More tests in testsuite | |
712 | ||
713 | - Add compatibility with uClibc again | |
714 | ||
715 | - Lookup modules.builtin.bin to decide if a module is built in kernel | |
716 | ||
717 | - Downgrade some log messages so we don't annoy people with useless messages | |
718 | ||
719 | - Bug fixes: | |
720 | - Flag --ignore-loaded was not being properly handled | |
721 | - Infinite loop with softdeps | |
722 | - Infinite loop with dumb user configuration with install commands | |
723 | - Fix leak in index when there's a partial match | |
724 | ||
725 | - Move repository and tarballs to kernel.org | |
726 | ||
e479598b LDM |
727 | kmod 5 |
728 | ====== | |
729 | ||
730 | - Break libkmod's API to insert a module like modprobe does. It now accepts | |
731 | extra an extra argument to print its action and acceptable flags were | |
732 | sanitized. | |
733 | ||
734 | - Share more code between modprobe and libkmod: using the new version of | |
735 | kmod_module_probe_insert_module() it's possible to share a great amount of | |
736 | code between modprobe and libkmod | |
737 | ||
738 | - modprobe no longer works with paths: it only accepts module names and/or | |
739 | aliases now. | |
740 | ||
741 | - testsuite was added to repository, allowing automated tests to be run and | |
742 | easing the way bugs are reproduced. | |
743 | ||
744 | - modprobe: when dumping configuration ('-c' option) separate config | |
745 | and indexes by adding a commented line between them. | |
746 | ||
747 | - Fix bugs wrt normalizing aliases and module names | |
748 | ||
749 | - Fix bug wrt inserting an alias that resolves to multiple modules: we should | |
750 | not stop on the first error, but rather continue to try loading other | |
751 | modules. | |
752 | ||
753 | - Fix unaligned memory access in hash function, causing depmod to output wrong | |
754 | information in ARMv5 | |
755 | ||
756 | - Fix man page build and install: now they are only installed if tools are | |
757 | enabled | |
758 | ||
b53b7e32 LDM |
759 | kmod 4 |
760 | ====== | |
761 | ||
762 | - New APIs in libkmod to: | |
763 | - Get configuration lists: blacklists, install commands, remove | |
764 | commands, aliases, options and softdeps | |
765 | - Dump indexes | |
766 | ||
767 | - Several bugs fixed in libkmod, modprobe, depmod and modinfo | |
768 | ||
769 | - API documentation: if configure with run with --enable-gtk-doc, the API doc | |
770 | will be generated by make. Gtk-doc is required for that. | |
771 | ||
772 | - Man pages are built, which replace man pages from module-init-tools | |
773 | ||
774 | - 'include' and 'config' options in *.conf files were deprecated | |
775 | ||
776 | - configure is not run by autogen.sh. Instead, a common set of options is | |
777 | printed. If you are hacking on kmod, consider using bootstrap-configure | |
778 | script. | |
779 | ||
780 | - 'modprobe -c' works as expected now. As opposed to module-init-tools, it | |
781 | dumps the parsed configuration, not only the file contents. | |
782 | ||
b30a71b8 LDM |
783 | kmod 3 |
784 | ====== | |
785 | ||
786 | - New APIs in libkmod to: | |
787 | - Get symbols from module, parsing the ELF section | |
788 | - Get dependency symbols | |
789 | - Check if resources are still valid or if libkmod must be reloaded | |
790 | - Insert module like modprobe, checking (soft-)dependencies, commands, | |
791 | blacklist. It can run commands by itself and to call a callback | |
792 | function. | |
793 | ||
794 | - Support to load modules compressed with xz | |
795 | ||
796 | - Tools are now bundled together in a single tool called kmod. It can be | |
797 | called using symlinks with the same names as tools from module-init-tools. | |
798 | E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a | |
799 | 1:1 replacement of module-init-tools. | |
800 | ||
801 | - The only missing tool, depmod, was added to kmod together with the necessary | |
802 | APIs in libkmod. | |
803 | ||
804 | - If a program using libkmod runs for a long time, as for example udev, it must | |
805 | check if it doesn't have to re-load libkmod. A new helper function was added | |
806 | in libkmod to check if context is still valid and udev is already using it. | |
807 | ||
808 | - An 'unaligned access' bug was fixed. So those architecture that does not | |
809 | handle unaligned access can use kmod, too. | |
810 | ||
acc18b14 LDM |
811 | kmod 2 |
812 | ====== | |
813 | ||
814 | Some bugs fixed: the worst of them was with an infinite loop when an alias | |
815 | matched more than one module. | |
816 | ||
817 | - New APIs in libkmod to: | |
818 | - Get soft dependencies | |
819 | - Get info from module files parsing ELF | |
820 | - Get modversions from files parsing ELF | |
821 | ||
822 | - Support to load gzipped kernel modules: kmod can be compiled with support to | |
823 | gzipped modules by giving the --enable-zlib flag | |
824 | ||
825 | - Support to forcefully load modules, both vermagic and modversion | |
826 | ||
827 | - Support to force and nowait removal flags | |
828 | ||
829 | - Configuration files are parsed in the same order as modprobe: files are | |
830 | sorted alphabetically (independently of their dir) and files with the same | |
831 | name obey a precedence order | |
832 | ||
833 | - New tool: kmod-modinfo | |
834 | ||
835 | - kmod-modprobe gained several features to be a 1:1 replacement for modprobe. | |
836 | The only missing things are the options '--showconfig' and '-t / -l'. These | |
837 | last ones have been deprecated long ago and they will be removed from | |
838 | modprobe. A lot of effort has been put on kmod-modprobe to ensure it | |
839 | maintains compabitility with modprobe. | |
840 | ||
841 | - linux-modules@vger.kernel.org became the official mailing list for kmod | |
842 | ||
89eba7cb LDM |
843 | kmod 1 |
844 | ====== | |
ecd40ee4 | 845 | |
89eba7cb LDM |
846 | First version of kmod and its library, libkmod. |
847 | ||
848 | In the libkmod it's currently possible to: | |
849 | - List modules currently loaded | |
850 | - Get information about loaded modules such as initstate, refcount, | |
851 | holders, sections, address and size | |
852 | - Lookup modules by alias, module name or path | |
853 | - Insert modules: options from configuration and extra options can be | |
854 | passed, but flags are not implemented, yet | |
855 | - Remove modules | |
856 | - Filter list of modules using blacklist | |
857 | - For each module, get the its list of options and install/remove | |
858 | commands | |
859 | - Indexes can be loaded on startup to speedup lookups later | |
860 | ||
861 | Tools provided with the same set of options as in module-init-tools: | |
862 | - kmod-lsmod | |
863 | - kmod-insmod | |
864 | - kmod-rmmod | |
865 | - kmod-modprobe, with some functionality still missing (use of softdep, | |
866 | dump configuration, show modversions) |
