2004-09-24Patch from Egor DudaGlenn L McGrath
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. egor.
2004-08-19Patch from Mike Castle to cleanup some modutils issues, inEric Andersen
particular making alias support work better.

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

change formatting).
2004-08-11Patch from Phil Blundellto improve substring matchGlenn L McGrath
2004-08-11Willian Barsse wroteGlenn L McGrath
"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."

fixes two other issues (plus the previous as well) with a 2.4 kernel : - should be able to modprobe an already loaded module and get 0 return code : # modprobe <something> && modprobe <something> && echo "ok" || echo "failed" .... failed Well, hope this helps and that I didn't screw up again, - William
2004-07-22Patch from Mike Snitzer <snitzer@gmail.com>:Robert Griebl
Support for /etc/modprobe.conf (for 2.6 kernels) should likely be added to bb's modprobe, see attached patch. modprobe.conf is just a (even simpler) variant of modules.conf

Hi, There was some problem with busybox modprobe. For details see http://www.busybox.net/lists/busybox/2004-May/011507.html I made a patch against busybox-1.00-pre10 to fix that one. This is a slight variant of Patrick's patch with a slightly cleaner implementation of mod_strcmp() -Erik

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 line, or alias w/o the value like alias some-module (syntactically incorrect, but no need for coredumps either).

alias 'off' parsing fix. It is not alias off module it is alias module off
2004-04-06Michael Tokarev, mjt at tls dot msk dot ru writes:Eric Andersen
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)

I have found the problem in modprobe, so here is the promised patch At the current stage I can use it as modprobe while switching between 2.4 and 2.6 seemlesly...(that is good!)
2004-01-06Woody Suwalski writes:Eric Andersen
accept more then 1 dependency per modules.dep line. Also white space cleanup... I think that parsing still breaks sometimes, but is mostly functional now.

2003-12-19Patch from Woody Suwalski:Eric Andersen
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. -Steve
2003-09-08Busybox modprobe has a couple of irritating quirks:Glenn L McGrath
- attempting to modprobe a module that is already loaded yields "Failed to load module", whereas modutils quietly ignores such a request. - if a module genuinely can't be loaded due to missing symbols or similar problems, modprobe doesn't produce any useful diagnostics because the output from insmod has been redirected to /dev/null. Here's a patch to address these issue Patch by Philip Blundell
2003-06-20Fall back to looking in /lib/modules/modules.dep ifEric Andersen

2003-06-20Patch from Andrew Dennison:Eric Andersen
I've had some issues with modprobe which I reported a few months ago. This is still an issue so I decided to sort it out. The attached diff includes the changes against the unstable cvs tree that work for me. Changes are: mod_process() will report success if the module at the head of the list loads successfully. It will also report success if any module unloads successfully. The net result being that modprobe will succeed in the cases outlined below. I've also added error reporting to modprobe -r. Previously it would silently fail (but report success) if the module could not be unloaded. Andrew

2002-07-02David Frascone <dave@frascone.com> noticed two problems. First, modprobe wasEric Andersen
trying to call 'insmod -q', which wasn't supported. Secondly, when modprobe was fed blank lines from modules.dep, we ended up calling xstrndup(ptr, -1), which with suitably bad results. David provided a patch to catch the blank lines, and I have added insmod -q support. So modprobe should work again. -Erik
