Summary

0000459: insmod on linux 2.4 x86_64 kernel fails with relocation errors

Description

Inserting a module into a Linux 2.4 x86_64 kernel using busybox.insmod failed due to relocation errors.

# ./modprobe e100
Using /lib/modules/2.4.21-15.EL/kernel/drivers/net/e100/e100.o
Warning: unhandled reloc 2
insmod: Unhandled relocation of type 2 for __const_udelay_Rsmp_eae3dfd6
Warning: unhandled reloc 2
insmod: Unhandled relocation of type 2 for e100_wait_scb
Warning: unhandled reloc 2
insmod: Unhandled relocation of type 2 for e100_exec_cmplx
Warning: unhandled reloc 2
insmod: Unhandled relocation of type 2 for alloc_etherdev_Rsmp_42ba5d18
Warning: unhandled reloc 11

The relocation code for x86_64 is missing from modutils/insmod.c. The supplied patch (from modutils-2.4.27) fixes the problem. I tested the patch with busybox-1.01 and busybox-20050930. I tested basic module loading but did not try to exercise every path through the new code. Here's how I applied the patch:

cd busybox-1.01
patch -p0 < ../insmod.patch
