See the "New features" item below. Measuring by commit count this is the biggest release since kmod-2! However most of it was due to improvements to the testsuite. In the beginning of this year I received complaints that kmod was shipping prebuilt GPL modules without distributing their source code. This happened because in order to test real world modules, I was taking any problematic module, putting it into the testsuite and writing tests for them. All the modules were GPL, coming from the kernel itself. Due to modversions I could even pinpoint the exact kernel version, but maybe this would not be sufficient for Debian. Instead of going this route, I decided to improve the testsuite, creating a "module-playground" in which we build our own modules tailored to the specific test. Some tests were rewritten, too. Now the only prebuilt modules we are shipping are the ones for different architectures since it would be too inconvenient to require cross-compilers on distro's build machines. But even those have rules in the build system to be recreated from source. For distros, what changes is that you need the kernel headers installed in order to run "make check". NEWS. - Bug fixes: - Handle bogus values from ELF, making sure they don't overflow whi= le parsing the file - Fix leak in depmod when -b flag is passed multiple times - Multiple minor fixes from static analysis by coverity and clang-analyze - Fix race between loading modules and checking if it's loaded in t= he kernel - New features: - There's a change in behavior regarding builtin modules: we now on= ly consider as builtin those that are present in modules.builtin ind= ex. Previously we were also checking the presence of /sys/module/, but this is racy and only modules that contain parameters are the ones creating a directory in sysfs. Now some commands will start to fail, e.g. "modprobe vt". Since v= t can't be compiled as a module it's not present in modules.builtin index. Previously we would report at as builtin, but now we fail because we couldn't find the module. - Improvements: - Integration of gcov into the build. Currently libkmod is at ~70% coverage and tools at ~50% by tests in the testsuite. Utility functions and structures in shared have more than 90% of coverage= . - Upload build to coverity - Improvements to testsuite: - Fix parsing return codes of init_module() calls - Add tests for utility functions in shared/ - Add tests for kmod_module_remove_module() - Add playground, in which our own modules are compiled - Port all tests to use modules from module-playground instead of copying prebuilt modules to the repository - Properly handle binaries that exit with no output - Besides comparing the output of commands, allow to copy to stdout/stderr Shortlog: Caio Marcelo de Oliveira Filho (6): tools: kmod: break iteration once a command is executed testsuite: add test for hash_add_unique testsuite: add test for growing then shrinking a hash testsuite: add more input cases to freadline_wrapped test util: remove dead code in freadline_wrapped testsuite: add tests for kmod_list Colin Walters (1): depmod: Fix crash in previous commit if root is not set David Herrmann (2): from systemd: build: check for build/link flags harder from systemd: build: make sure to test for -Wflag instead of -Wno-fla= g Harish Jenny K N (1): Fix race while loading modules Lucas De Marchi (78): NEWS: Fix typos README: move mailing list information to top build-sys: Don't add libkmod subdirectory to include path build-sys: Don't define LIBEXECDIR build-sys: set -e separately, rather than putting -e in the shebang l= ine Remove FSF mailing address Fix includes after change to build-sys libkmod-elf: Remove unused variables Fix include in python bindings build-sys: rename cflags/ldflags variable testsuite: do not overrid paths inside build build-sys: integrate coverage report testsuite: add test for array_pop() Update TODO CODING-STYLE: add include order tools: kmod: use streq testsuite: fix retcodes parsing shared: add STRINGFY macro testsuite: test kmod_module_remove_module for failure testsuite: prefer the use of streq() tools: prefer the use of streq() testsuite: improve assert report testsuite: improve coverage of shared/util.h build: enable LTO and _FORTIFY_SOURCE with optimization build: pass --no-undefined to linker Fix uninitialized warning Revert "build: enable LTO and _FORTIFY_SOURCE with optimization" Update TODO testsuite: beef up module-playground in the build system testsuite: use mod-simple.ko for search-order-same-prefix test testsuite: make test-dependencies use DEFINE_TEST testsuite: port test-dependencies to module-playground build: let touch on directory as last step testsuite: convert test-init function to use mod-simple.ko travis: use kernel headers for testsuite travis: also test with gcc 4.8 and 4.9 testsuite: port detect-loop test to module-playground build: add better check for builtin function build: check for required builtin functions testsuite: port show-depends tests to module-playground build: define to 0 if builtin is not available shared: add helper function to add and check for overflow libkmod: use helper function to check for overflow testsuite: port softdep-loop test to module-playground testsuite: port modprobe --force test to module-playground testsuite: port tests without finit_module() to module-playground testsuite: port alias-to-none test to module-playground testsuite: port install-cmd-loop test to module-playground testsuite: port kcmdline test to module-playground libkmod: consider empty signature key as invalid libkmod: better explain a signed module layout Update TODO testsuite: port modules-order-compressed to module-playground module-playground: allow to cross-compile modules testsuite: fix exiting with success on no output activity testsuite: add option to copy output from test testsuite: leave arch-specific modules in tree fixup!
