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

With -Wstrict-aliasing=2 we get the following warning:
libkmod/libkmod-signature.c:124:20: note: in expansion of macro 'get_unaligned'
sig_len = be32toh(get_unaligned(&modsig->sig_len));
However there's nothing wrong with it. modsig->sig_len is uint32_t and
get_unaligned in this case returns uint32_t. There's notstrict aliasing
violation.

From Jan Engelhardt:
Program received signal SIGBUS, Bus error.
[Switching to process 11100]
0x00035278 in kmod_module_signature_info (file=0x4eeb8, sig_info=0xffffc254)
at libkmod/libkmod-signature.c:124
124 sig_len = be32toh(modsig->sig_len);
(gdb) p modsig
$1 = (const struct module_signature *) 0xf7dfe143
modsig->sig_len can be unaligned if modsig is unaligned, so the padding
in the struct has no effect since we are mapping it to the mem buffer.

Test depmod with search dirs "foo" and "foobar". Previously to 49b33c1
("depmod: do not allow partial matches with "search" directive") we were
failing this test due to matching the prefix without checking if
it's the full dir name.
We are adding 2 tests here in order to catch the case we only pass the
test due to processing the directories in a favourable order.

Currently e.g. "search foo foobar built-in" will cause unpredictable
results if baz.ko is in both foo/ and foobar/, since "foo" in search may
match both of those directories and the preferred module therefore
depends on processing order.
Fix the code to ensure that the match is performed on full pathname
components only.

Commit 51c409b ("Cache the offset of crc") unintentinally changed the
comparison "if (elf->class & KMOD_ELF_32)" to
"if (elf->class == KMOD_ELF_32)".
This has been reported by Serge Voilokov <serge0x76@gmail.com>:
On Raspberry PI elf->class equals KMOD_ELF_32|KMOD_ELF_LSB so
valid condition should be (elf->class & KMOD_ELF_32) instead of
(elf->class == KMOD_ELF_32).
This fixes "modprobe --dump-modversions" failing on 32b systems.

In a specific configuration (chroot with the linux32 personality), the
modprobe_install_cmd_loop test failed, because the bash process handling
the install command segfaulted. The backtrace showed a uname() call
during libpthread initialization, at which point the environ pointer
hadn't been initialized yet:
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x080c1591 in getenv (name=<optimized out>,
name@entry=0xf775f850 "TESTSUITE_UNAME_R") at getenv.c:81

(gdb) bt

I don't know why it only happend in the chroot, but glibc can call its
own functions and impose any restrictions before main() is started, so
we have to adapt.
Also, do not return error if there is an environment, but the
environment variable is not found. If uname() is called by kmod, then
the respective test will simply fail later. If it's something else
calling uname(), then we do not want to disturb the program.

Nowadays udev doesn't create nodes in /dev anymore. This role is rather
taken by systemd-tmpfiles on early boot so reference it generically as
systemd.

configure: Do not require xsltproc for installation of man pages
The release tarballs ship with pre-generated man pages, so we do not
need xsltproc for a typical end-user build.
Developers will probably have xsltproc anyway, but if not they will now
encounter a build-time failure instead of an error in configure.

These redirecting makefiles simplifies compiling from some editors and
when CWD is not the root of the source tree. This is similar to what was
introduced in systemd in 340d89e ("build-sys: add small redirecting
Makefiles to simplify compilation from within emacs")

In kcmdline it's possible to have a dot in the param's value. The
support for this was added in 66f3228 ("libkmod: Add support for '.' in
module parameter on kcmdline") and is needed to correctly support some
modules that depend on it.
This test was added in order to make sure the commit aa87854
("libkmod-config: Only match dot before '=' in /proc/cmdline") didn't
break it. Although that commit message says it's allowing to match a
dot before '=' it's actually enforcing the first part of the string to
be always in the format "<module-name>.param". Dots after '=' are still
correctly allowed.
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
Strings unrelated to modules and modprobe should be ignored and not
appear in the output of "modprobe -c".
This adds a test for the fix provided in aa87854 ("libkmod-config: Only
match dot before '=' in /proc/cmdline").
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | | |
We are not only checking if those options are correctly parsed from
kcmdline, but if in fact they are being passed to the final
(f)init_module call. This is why we use 'modprobe --show-depends'
instead of the simpler 'modprobe -c'.
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
Use "modprobe -c" to dump the configuration. Since we configure our
rootfs to have only a /proc/cmdline file, this should dump the knowledge
we have from its parsed content.
Test if <module>.option, without any value is correctly parsed, as fixed
in commit 493dc65 ("libkmod: Fix getting param with no value from kcmdline")
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
Otherwise, we also parse strings like
BOOT_IMAGE=/boot/vmlinuz-3.12.12-57.g5f654cf-default
In practice, this is not a problem, because there is no module named
BOOT_IMAGE=/boot/vmlinuz-3. It just disturbs in modprobe -c output.
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
If we can open it and read it, it's good enough for us. Otherwise, we
cannot use -C /dev/null to skip the system configuration for instance:
$ ./tools/modprobe -C /dev/null -c
libkmod: ERROR libkmod/libkmod-config.c:821 conf_files_list: unsupported
file mode /dev/null: 0x21b6
...
|
| | | |
| | |
| | |
| | |
| | | |
Store the file and elf pointer in the kmod_module structure and have it
freed together with the module.
|
| | | | |
|
| | | |
| | |
| | |
| | |
| | | |
If the test's uname -r is less that 3.8, return -ENOSYS from
finit_module(), so that the fallback is tested.
|
| | | |
| | |
| | |
| | |
| | | |
There is no check if the correct flags are passed to finit_module, but
at least we cover the respective code path in kmod.
|
| | | |
| | |
| | |
| | |
| | |
| | | |
Add a ->modules_loaded member to struct test, which is a comma-separated
list of modules that should be present after the test finishes. Both
missing and excess modules cause an error.

This patch removes the cmdopts declaration and the documentation. They
were leftover from the -w removal.

Also define noreturn w/o <stdnoreturn.h> and move it to macro.h instead
of in the testsuite.
