If we are accessing a file inside the build directory we should really
not trap the path. Right now this isn't important because we never do
such accesses. However it will be needed when gcov is integrated because
it dumps files to the same place where the binaries are located.
Make the includes be libkmod/libkmod.h for code outside of library. This
fixes the broken build after 1315123 ('build-sys: Don't add libkmod
subdirectory to include path').
It has changed in the past, and these days, anyone can get a copy of the
LGPL via the web rather than by post.
Like 657a122 (Remove FSF mailing address) in libabc by Josh Tripplet,
but let the FSF website in which the license can be found.
The -fdiagnostics-color flag is only available on GCC >= 4.9, for
older versions this could raise an error in certain circumstances
(such as when using ccache). Instead, since -fdiagnostic-color=auto
by default in gcc-4.9, simply set the required environment variable
to the default one if it's undefined.
Based mostly on the systemd commit f44541bc by Michal Schmidt.
Instead of repeating all documentation, point to the documentation
available in libkmod-index.c
This also removes INDEX_PRIORITY_MIN that was not being used.
Just like other source files, keep the index and comments in the source
file rather than the header.
This also removes INDEX_PRIORITY_MIN that was never being used.
udev will only manage static nodes that exist at the time udev is started, so
creating static nodes later on will likely not behave as expected. In
particular, recreating the static nodes at run-time will reset any permissions
udev may have applied to the nodes at boot.
See <https://bugzilla.redhat.com/show_bug.cgi?id=1147248> and the discussion
following <http://permalink.gmane.org/gmane.comp.sysutils.systemd.devel/23795>.
Note that this requires (the yet to be released) systemd v217 or a backport
of systemd patch 8c94052ee543c3598a3c7b0c46688150aa2c6168.
Using 2048 as buffer sizer for strbuf is a bit exaggerated. strbuf is
used much more when we are not using mmapped indexes, but it's used for
mmapped when for example searching for an alias. A quick and dirty hack
to output the size of our strbufs is to print buf->used inside
strbuf_str(). Doing this and creating some statistics with:
while read xxx alias xxx; do
tools/modprobe -R "$alias" > /dev/null;
done < /lib/modules/$(uname -r)/modules.alias 2>&1 | \
Rscript -e 'summary (as.numeric (readLines ("stdin")))'
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's
1.00 29.00 31.00 31.55 38.00 92.00 26
So, reduce the step to 128, which is still greater than the maximum in
these cases. In the worst case this can only create a few calls to
realloc(), while keeping the memory footprint low for the common cases.
Intead of having to declare an array of tests, tweak the definition of
DEFINE_TEST and TESTSUITE_MAIN so they know the tests are put in a
particular section of the ELF file.
This avoids the mistake of adding a test and forgetting to add it to the
array. Now once a test is defined, it's ready to run, so one less step
to define new tests.
The removal of the arrays is left for another patch so not to clutter
the diff on this one.

It doesn't really matter in the end result since the compiler won't
generate any code for it. But let's keep it clean. It wasn't needed
until now, so probably it won't be anymore.
Move underscores() to shared/. It's the same as alias_normalize(), but
it rather operates in place, with the same string being passed.
The difference now that it's in shared/ is that it's a non-logging
function.
This makes us a little bit more verbose: we don't accept partially
correct module and aliases names in kcmdline and in configuration files.
We log an error instead.
This function was declared as always-inline so there was not really a
problem in returning prioname, that could possibly point to the local
buf[] variable.
However static analysis tools are often confused about this and being
always-inline was just a workaround to make it work.
So, let's move the buffer to the caller. We have only 2 callers so it
doesn't matter much. This always reduce the size of log.o, since now the
function is not inlined anymore. Below is the size for "-g -O2" with
gcc:
before:
text data bss dec hex filename
1325 4 1 1330 532 tools/log.o
after:
text data bss dec hex filename
1171 4 1 1176 498 tools/log.o
The only user outside of libkmod-util is depmod, which really only needs
to get the string for the extension of uncompressed modules. It doesn't
need to access the array itself.
