kmod can use xz to read lzma compressed modules, however kmod is
needed in foundation, which doesn't have xz

The reason to have a kmod-nolib binary is that we need to call kmod on
test cases (or a symlink to it) and for testing things in tree. Since
we are using libtool if we are dinamically linking to libkmod what we
end up having is a shell script that (depending on the version *)
changes argv[0] to contain an "lt-" prefix. Since this screws with our
compat stuff, we had a kmod-nolib that links statically.
This all workaround works fine iff we are using one of the compat
commands, i.e. we are using the symlinks insmod, rmmod, modprobe, etc.
However if we are actually trying the kmod binary, this doesn't work
because we can't create a kmod symlink since there's already a kmod
binary.
So, completely give up on libtool fixing their mess. Now we create a
tool/test/ directory and the symlinks and kmod is put there.

Do the same as done in systemd by Cristian Rodríguez
<crrodriguez@opensuse.org>. We use private symbols, not namespaced. So
don't pretend we support static linking.

At least in qemu 1.4.1 for vexpress/arm-cortexa9, this resulted in an
illegal instruction error. Solve that by returning an error when
__NR_finit_module is -1.

This reverts commit 38829712e5c411bc250aeae142fc6bf06e794d58. It fixes
the problem, but it breaks the testsuite for those who don't have
__NR_finit_module. The testsuite would have to make the same check.
Instead, I'm reverting this change and I'm going to apply another patch
from Jan Luebbe who got this right from the beginning.

There are several exported enums by libkmod without document, this patch
mainly added documentation for below enums like the way kmod_resources
be documented in.
* kmod_index
* kmod_remove
* kmod_insert
* kmod_probe
* kmod_filter
* kmod_module_initstate
This is not the best way to document these exported enums, however, it's
the simple way due to gtkdoc limits. It doesn't support export plain
enum like below: see https://bugzilla.gnome.org/show_bug.cgi?id=657444
---------8<-------head.h--------------8<-----------
...
enum foo {
...
};
...
---------8<-------end of head.h-------8<-----------
---------8<-------source.c------------8<-----------
...
/**
* document for foo here
*/
...
typedef enum foo foo;
...
---------8<-------end of source.c-----8<----------

The modprobe.d (5) documentation for the "install" command
states that you could specify
install fred /sbin/modprobe barney; /sbin/modprobe --ignore-install fred
This makes some sense, but then the loading of "barney" is
hidden from the user who did only "modprobe fred". Thus,
it seems it should be possible to be able to unload the
"fred" module with "modprobe -r fred" by configuring the
"barney" module to also be removed:
remove fred /sbin/rmmod barney fred
(or similar.)
Make this possible by not checking the refcount when an
unload command was configured.

When passing n=0, don't pass a NULL pointer, but instead pass anything
else (like the pointer to the start of the string).

Add __attribute__((format)) to log_filep() and _show() functions, fixing
the bugs they found in the source code.
For functions that receive va_list instead of being variadic functions
we put 0 in the last argument, so at least the string is checked and we
get warnings of -Wformat-nonliteral type. So, it's better than adding a
pragma here to shut up the warning.

kmod uses tab instead of spaces and tries to honour 80chr limit, when
that doesn't worsen the readability.

This file is created by depmod even if there's no node. In this case it
will be empty.
Previously 'kmod static-nodes' was segfaulting due to passing in==NULL
to fgets.

This tool reads modules.devname from the current kernel directory and outputs
the information. By default in a human-readable format, and optionally in
machine-readable formats.
For now only the tmpfiles.d(5) format is supported, but more could easily be
added in the future if there is a need.
This means nothing but kmod needs to reads the private files under
/lib/modules/. In particular systemd-udevd can stop reading modules.devname.
Tools that used to read /lib/modules/`uname -r`/modules.devname directly, can
now move to reading 'kmod static-nodes devname'.

Both GCC and clang already supports C11's _Static_assert, so use it
instead of defining our own macro.

Automake < 1.13 doesn't enable parallel tests by default, so add it to our
automake options.

Use an if instead of a case statemente. If __NR_finit_module is not
defined in system headers we define it to -1, causing a "duplicate case
value" error. Yet, we don't want to actually call our finit_module()
function if -1 is passed.
This also fix errno being set with negative value.

When we don't have finit_module() in libc (most likely because as of
today glibc didn't add it yet), we end up using
syscall(__NR_finit_module, ...). In this case we would not wrap the
function in the testsuite and thus having some tests failing:
TESTSUITE: ERR: could not insert module: Operation not permitted
This implementation relies on the fact that this is the only caller of
syscall(2), because we can't call libc's syscall(). There's an abort()
in place to be future safe: as soon as we need more calls to syscall(),
we can detect (and decide what to do).
Now we have all tests passing in the testsuite again.

Check for finit_module() and don't use our own static inline function if
there's such function in libc (or another lib).
In testsuite we need to unconditionally define HAVE_FINIT_MODULE because
we want to override this function, and never use the static inline one
in missing.h
|
| |
| |
| |
| |
| |
| |
| | |
Depending on kernel header and simply not passing the flags in
finit_module() if this header is not found is not good.
Add a missing.h header in which stuff like this should be added.

Putting something like "alias psmouse deadbeef" is a hackish way to
blacklist a module. While I don't encourage doing so, let's not explode
if we fiund such config files.
A small difference from the behavior of module-init-tools: we exit with
0 instead of 1.

Put this one /etc/modprobe.d/bougs.conf:
alias psmouse deaddood
`modprobe --show-depends --quiet psmouse` explodes in an assertion
(unless you have a module named deaddood). Some people and initrd's use
"alias psmouse off" to disable a module instead of blacklisting it or
adding a install rule.
Add a test with expected_fail == true before fixing this.
