Description of problem: loading the ipt_MASQUERADE module with modprobe fails with the following error with 2.4.20-1.1988 (UP athlon) /lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o: 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/ipt_MASQUERADE.o:/lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_tables.o \ /lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ip_conntrack.o \ /lib/modules/2.4.20-1.1988/kernel/net/ipv4/netfilter/ipchains.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/ipt_MASQUERADE.o: /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 \ /lib/modules/2.4.21-rc2-ac1/kernel/net/ipv4/netfilter/ip_conntrack.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.
fix: change modules dependencies from /lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ipt_MASQUERADE.o: /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/ip_tables.o to /lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ipt_MASQUERADE.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 \ /lib/modules/2.4.20-1.1992smp/kernel/net/ipv4/netfilter/ip_tables.o
Still present in 2.4.20-20.1.2013.nptl
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)
Same bug has been reported as a public bug later -> make this one public and a duplicate of that one *** This bug has been marked as a duplicate of 98241 ***
