These ext4 modules were sent by Jon Master so we can test the result of
modinfo with modules generated for different architectures.
They are now added to testsuite and their output tested automatically.
Tests may put the correct output in a file and tell testsuite to check
if it matches the output from the test running.
Testsuite compares the outputs while running the test: it creates a pipe
between parent and child; parent reads both stdout and stderr from child
and compares with the correct output.
In order to locate where the shared libs to be preloaded are we need to
reference them using abs_top_buildir. Otherwise we are limited to
running tests from there.
Add trap to stat(): we need to trap other functions too, depending on
stat.h, the function from glibc that is actually called may be stat64 or
__xstat() too.
A certain config can add flags and each flag may be associated with a
lib to LD_PRELOAD. It's now done for uname(2), which requires uname.so
in order to trap the calls.
Other trap will be added in later commits.
Distro packagers should create them instead. It's too much trouble to
create them in the build system and every distro wants a different path
for them.
It was not on module-init-tools and it doesn't make much sense. It will
deal with dependencies, but looking at modules in the index. This might
not be the module we want if we are loading another from outside of the
tree.
Dealing with paths causes this bug (supposing there's a module names
squashfs):
# cd /
# touch squashfs
# modprobe squashfs
That is because it detects that squashfs exists as a file and it will
try to load it instead of the alias "squashfs".
If you need to load a module from a path, use insmod.
Thanks to Silvan Calarco <silvan.calarco@mambasoft.it> who reported the
bug and helped debugging it.
Not all libc's have a mtim member in struct stat (dietlibc doesn't).
Change ts_usec() to receive a struct stat as parameter and implement it
accordingly for both cases.
Index dump doesn't use stdio.h function and instead call write()
directly on STDOUT_FILENO file descriptor. Therefore we need to flush
stdio buffers before calling it, to be sure the configuration dump will
appear before index's.
Provide a function to dump the index files to a certain fd. It could be
more optimized (particularly the functions to dump the index that were
copied and pasted from m-i-t), but it seems like the only user of it is
'modprobe -c', used for debugging purposes. So, keep it as is.
