Subject: [parisc-linux] kernel module relocation bug
Date: Fri, 26 Nov 2004 22:47:10 -0800	[thread overview]
Message-ID: <20041127064710.GL9148@tausq.org> (raw)

currently the kernel module loader does not support long branch stubs.
using the debian 2.6.8-1 kernel, when loading the ipv6 module, i see:

legolas[6:43] linux-2.6% sudo modprobe ipv6
FATAL: Error inserting ipv6 (/lib/modules/2.6.8-1-32-smp/kernel/net/ipv6/ipv6.ko): Invalid module format

in syslog, i get:
module ipv6 relocation of symbol fold_prot_inuse is out of range (0x3ffeffe2 in 17 bits)

these are the other modules i have loaded at the moment:

legolas[6:26] linux-2.6% lsmod

sd_mod                 24416  5
sym53c8xx             105004  4

the kernel i have is:
Linux legolas 2.6.8-1-32-smp #1 SMP Tue Nov 2 13:07:05 MST 2004 parisc
GNU/Linux

to fix this we will probably need to introduce long branch stubs into 
into the kernel module loader. anybody want to give this a shot?
