15d3f7f143 Takeharu Kato's patch added 2.6 support to lsmod; this changes menuconfig
dependencies so 2.6 support depends on insmod or lsmod...

I found that lsmod in busybox does not support linux-2.6.
I fix this issue(it is caused by changes of /proc/modules format).
If you use lsmod in busybox with kernel-2.6, please use this patch.

Hi!

I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.

That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.

I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.

'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.

One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

bdf6319d3a Patch from Egor Duda
Attached patch prevents modprobe from trying to call 'insmod (null)'
whenever nonexistent module is either passed to modprobe via command
line or mentioned in modules.dep

this replaces cryptic error
sh: Syntax error: word unexpected (expecting ")")
with
modprobe: module some-module not found.

45a0513a64 Based on patches from Mike Frysinger, add insmod support for
sparc and ia64 (itanium).

Also, reorganize the insmod architecture support code to be
alphasorted and less messy.

Update the readme to list current insmod arch support.

Hello,

function build_dep in modprobe.c assumes that dependencies of one module
have not more than 255 chars;
that is not sufficient in kernel 2.6.7 (alsa sound modules). - Below is
a diff that solves the problem for me.

With regards, Christian Ostheimer

"There seems to be a slight problem with the "mod_strcmp" function in
modprobe.c, it scans for the first occurence of the module name in the
"mod_path" variable and expects it to be the last path element. ie
/lib/modules/2.4.22-debug/kernel/fs/vfat in my example. The comparison
will always fail if mod_path contains another substring matching the
module name."

Robert McQueen wrote
"Although William Barsse's patch fixed mod_strcmp for 2.4 kernels, there
was a remaining problem which prevented it from working for me. I've
just tracked it down - when you enable kernel 2.6 module support it
hard-wired the extension to .ko instead of checking at runtime like the
other places where 2.4 differs from 2.6. The attached patch fixes this
for me."

Hi,

    There was some problem with busybox modprobe. For details see

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be
passed to the upstream authors.

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?

Good luck on the 1.00 release!

Fix parsing of all tag-value pairs (in modules.conf in particular).
Without this fix, code chokes badly on lines where either value or
both tag+value are missing, like bare

 alias some-module

Initialize all fields of struct dep_t.
Without that, e.g. `busybox modprobe -v char-major-10-144' *sometimes*
fails this way (strace):

 write(1, "insmod    nvram `\213\f\10\n", 21) = 21

Note the garbage after module name which is taken from the m_options field,
which is not initialized in the alias reading/parsing part.
(Shell properly complains to this command, telling it can't find the
closing backtick)

3f47c453da Christian Grigis, christian.grigis at smartdata dot ch writes:
Hello everyone,

Busybox's insmod fails to locate a module when that module is the only one
existing in the /lib/modules directory (with a unique name).

Example:

# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
# insmod bios
insmod: bios.o: no module by that name found
# touch /lib/modules/dummy
# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
/lib/modules/dummy
# insmod bios
Using /lib/modules/kernel/drivers/char/bios.o

As long as there is another file in the /lib/modules directory, insmod
finds it OK.

I tracked the problem down to 'check_module_name_match()' in insmod.c:

It returns TRUE when a match is found, and FALSE otherwise. In the case
where there is only one module in the /lib/modules directory (or more that
one module, but all with the same name), 'recursive_action()' will return
TRUE and we end up on line 4196 in 'insmod.c' which returns an error.
[The reason it works with more than one module with different
names is that in this case there will always be one not matching,
'recursive_action()' will return FALSE and we end up in line 4189.]

Now, from the implementation of 'recursive_action()' and from other
usages of it (tar.c, etc.), it seems to me that FALSE should be returned
to indicate that we want to stop the recursion, so TRUE and FALSE should
be inverted in 'check_module_name_match()'.

At the same time, 'recursive_action()' continues to recurse even after
the recursive call has returned FALSE; again in my understanding and
other usages of it, we can safely stop recursing at this point.


Here is my patch against 1.00-pre8:

03d8091859 Patch from Woody Suwalski:
Erik, I think we have met online some time ago when I was in Corel/Rebel
    Netwinder project....

Anyway, I would like to use BB on 2.6.0 initrd. 1.00-pre4 works OK, if
insmod is actually presented with a full path to the module. Otherwise -
problems (not to mention conflicts when 2.4 modutil is enabled)

Here are some patches for insmod and modprobe which try to walk around
the default ".o" module format for 2.2/2.4 modules (you have probably
noticed it is now .ko in 2.6 ;-)) Trying to steal as little space as
possible if 2.6 not enabled...

The modprobe is still not perfect on 2.6 - seems to be jamming on some
dependencies, but works with some (to be debugged). Anyway after the
patches it at least tries to work....

Will there be a 1.00-pre5 coming any time soon?

Thanks, Woody

Hey guys. I've found a bug in modprobe where it generates bad strings and
makes sytem calls with them. The following patch seems to have fixed the
problem. It is rather inherited elsewhere, as there seems to be incorrect
entries in the list which results in more dependencies than really exist for
a given call to mod_process. But, this patch prevents the bad text from
going to the screen. You will notice there are cases where lcmd goes
unmodified before calling system.

Please consider the following patch.

Thanks.
