Description Pekka Pietikäinen 2003-05-11 17:42:28 EDT
Description of problem:

loading the ipt_MASQUERADE module with modprobe fails with the following error
with 2.4.20-1.1988 (UP athlon)

init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o: insmod
/lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o failed
/lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o: insmod
ipt_MASQUERADE failed

Looking at the reason why it doesn't load the following dependancy is found
(ie. it tried to load ipchains.o, which fails since ip_tables is loaded)

        /lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o \

In a self-compiled 2.4.21-rc2-ac1 (just about identical kernel config
in the networking side) the dependancy is 

/lib/modules/2.4.21-rc2-ac1/kernel/net/ipv4/netfilter/iptable_nat.o \
        /lib/modules/2.4.21-rc2-ac1/kernel/net/ipv4/netfilter/ip_tables.o \

and everything works, so does 2.4.20-9. Nuking ipchains.o and ipfwadm.o in
2.4.20-1.1988 makes it work as well.
Comment 1 Philip Kelley 2003-05-16 11:43:02 EDT

change modules dependencies from

/lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ipchains.o \
        /lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ip_conntrack.o \


/lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/iptable_nat.o \
        /lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ip_conntrack.o \
Comment 2 Alexandre Oliva 2003-06-17 14:15:18 EDT
Still present in 2.4.20-20.1.2013.nptl
Comment 3 Gerald Teschl 2003-06-28 14:48:07 EDT
I just compiled 2.4.21 + acpi + swsusp and it has the same problem. I am using
the same config file (execpt for acpi turned on), so either this is a config
problem or it is in one of the patches 600 or above (I removed all patches
before 600 to make swsusp happy)
Comment 4 Pekka Pietikäinen 2003-07-22 08:29:00 EDT
Same bug has been reported as a public bug later -> make this one public and a
duplicate of that one
