I have a problem compiling a module that I am porting form 2.4 to 2.6 linux kernel.
Compiling with this Makefile:
DEBUG = y
KERNELDIR = /usr/src/linix.2.6.9
SUBDIR = $(KERNELDIR)/drivers/snoop
INCLUDEDIR = $(KERNELDIR)/include
obj-m := snoop.o
modules: $(MAKE) -C $(KERNELDIR) SUBDIR=$(SUBDIR) modules
clean:
rm -f *.o
rm -f *.ko
apperars some lines like:
***Warning: "snoop_ip_forward" [drivers/snoop/snoop] is COMMON symbol
***Warning: "snoop_ip_forward_finish" [drivers/snoop/snoop] is COMMON symbol
and I have insert in ip_forward.c some lines:
extern int (* snoop_ip_forward_finish) (struct sk_buff *);
and this is in function ip_forward():
if(snoop_ip_forward && (*snoop_ip_forward)(skb) == -6)
goto drop;
then when I try to install the module it repyes with:
insmod: error inserting 'snoop.ko': -1 Invalid module format
and in /var/log/message appears some lines line:
kernel: snoop: Unknown symbol __floatsidf
kernel: snoop: Unknown symbol __fixunsdfsi
kernel: snoop: Unknown symbol __adddf3
kernel: snoop: Unknown symbol __muldf3
I will be very pleased if you can help me in some way.
thank you for your time
regards,
Raffaele

I don't know what the ***Warning's are, but the first 2
problems to solve are:
a. use a proper 2.6 Makefile: see Documentation/kbuild/*
and http://lwn.net/Articles/driver-porting/
or see an example at
http://www.xenotime.net/linux/modprms/Makefile
IOW, you need to use the 2.6 build system.
b. The code is being generated with some floating point
operations in it. Linux kernel does not (generally)
allow/support FP operations in kernel code, so you'll
need to use some other method for those calculations.
(unless this problem goes away because of using the
correct 2.6 build system tools)
