Description Gerd Hoffmann 2007-07-12 15:02:28 UTC
Description of problem:
/sbin/weak-modules fails to handle inter-module symbol references.

Version-Release number of selected component (if applicable):
module-init-tools-3.3-0.pre3.1.16.0.1.el5

How reproducible:
grab xenpv-kmod packages from
http://devserv.devel.redhat.com/~ghoffman/brew/rhel51-xen/$arch/, install them.

Actual results:
Only xen-platform-pci.ko gets symlinked into weak-symbols

Expected results:
all xen-*.ko modules get symlinked into weak-symbols

Additional info:
xen-platform-pci.ko provides symbols referenced by the other modules.

Comment 1 Gerd Hoffmann 2007-07-19 16:17:29 UTC
Bug is in the module_is_compatible() function.

modprobe prints 8-char-wide crc's.
nm dumps 16-char-wide addresses.
thus they don't look identical to the join utility.

Probably happens on x86_64 only.
