Bug 35061 – lufs has several unresolved symbols when attempting to modprobe

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sumit Khanna 2003-12-04 08:18:05 UTC]

I'm using lufs 0.9.7 with gcc 3.3.2-r3 and gentoo-test-sources
(linux-2.4.22-gentoo-r1). Lufs compiles fine, however when I try to modprobe it,
I get the following unresolved symbols.

/lib/modules/2.4.22-gentoo-test-r1/kernel/fs/lufs/lufs.o: insmod lufs failed
[/code]

I realize the gentoo kernel adds several patches to the original kernel source.
Is there anyway to change my kernel config so that lufs will work with it, do I
simply need to use vanilla-sources, or does lufs just need to be patched for
newer kernels? 

Reproducible: Always
Steps to Reproduce:
1. boot gentoo with gentoo-test-sources (linux -2.4.22-gentoo-r1)
2. emerge lufs (make sure /usr/src/linux points to the right sources)
3. modprobe lufs

Actual Results:  
the lufs module fails to load

Expected Results:  
load the lufs module

I can confirm this same behaviour with gs-sources-2.4.23_pre8-r1 as well.

[Comment 2 Brian Jackson (RETIRED) 2003-12-05 11:20:25 UTC]

I see some symbols that are specific to the patches in the new gentoo-sources, but then there are some symbols (kmalloc, kfree, etc.) that would be in every kernel. None of those symbols are tied to any one config option, so I don't think it's a matter of changing a config option. It looks like lufs is some how not finding the right stuff from gentoo-sources. I'll take a peek at how lufs finds all the stuff it needs.

[Comment 3 Matthew Almond 2003-12-10 12:29:36 UTC]

I believe this is the same problem as:

http://sourceforge.net/forum/forum.php?thread_id=972236&forum_id=192378

I've made a patch that seems to apply okay (it modifies configure.in, so I re-run autoconf after) but it bombs out with a sandbox error, any ideas?

Not quite, but nearly working ebuild

This doesn't build yet, but it does include the patch described (I think!) -
the bit that doesn't work is the depmod - it comes up with the following error:


make[5]: Entering directory
`/var/tmp/portage/lufs-0.9.7-r1/work/lufs-0.9.7/kernel/Linux/2.4'
depmod -aq
ACCESS DENIED  open_wr:   /lib/modules/2.4.22-gentoo-r1/modules.dep

Any ideas?

[Comment 5 Robin Wood 2003-12-18 15:37:55 UTC]

I get the large list of unresolved symbols similar to below if I try to compile from source but the following if I use lufs-0.9.7.ebuild.

depmod: *** Unresolved symbols in /lib/modules/2.4.20-gentoo-r9/kernel/fs/lufs/lufs.o

I am on kernel 2.4.20-gentoo-r9.

[Comment 6 Jason Cox (RETIRED) 2004-04-08 21:05:34 UTC]

Is this problem still around? Have you tried a newer kernel?

[Comment 7 Jason Cox (RETIRED) 2004-04-09 08:00:33 UTC]

Four months. Just a tad old. Marking closed.

> Is this problem still around? Have you tried a newer kernel?

Yes and yes. The problem persists with 2.4.25 gentoo-sources kernel (as can be expected after reading the forum linked to in an older comment). Submitted patch fixes it, can it please be applied to CVS?

Attached patch fixes reported sandbox violation (the patch is against CVS
version and contains both violation fix and fix for unresolved symbols from
previously submitted ebuild update).
