Most visible change is a change in behavior regarding builtin modules.
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 while
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 the
kernel
- New features:
- There's a change in behavior regarding builtin modules: we now only
consider as builtin those that are present in modules.builtin index.
Previously we were also checking the presence of
/sys/module/<module-name>, 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 vt
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
