Is there anyone here that builds kernel modules that might

provide some insight into what might have changed in the kernel between 2.6.25.3-18.fc9.i686 and 2.6.25.4-30.fc9.i686 to cause an invalid module format to be built? These are, I believe the next to last and last kernel updates, respectively.

The builds under both kernels appear to run correctly (no

error messages) but when you try install the module it errors:

[root@wimsey vpnclient]# /etc/init.d/vpnclient_init start
Starting /opt/cisco-vpnclient/bin/vpnclient: insmod: error

inserting '/lib/modules/2.6.25.4-30.fc9.i686/CiscoVPN/cisco_ipsec.ko': -1 Invalid module format

Failed (insmod)

After building the packages run dmesg to see how they are loaded. $ su -

password:
# modprobe cisco_ipsec

what does it give you?

then run dmesg on the same terminal or another tabbed one
$ dmesg

should output something back about compatibility.

This is the vpnclient-linux-x86_64-4.8.01.0640-k9_f8.tar.gz build from Cisco (obtainable from ftp://ftp.tu-graz.ac.at/vc-graz/vpn/vpnclient-linux-x86_64-4.8.01.0640-k9.tar.gz

as modified by the patch from
http://projects.tuxx-home.at/ciscovpn/patches/vpnclient-linux-2.6.24-final.diff

The patch is for 2.6.24 kernels right?, there were some changes in the newer 2.6.25 kernels, the fastcall, FASTCALL() procedures were removed. I had a problem with building drivers for a modem, I have an external modem, but could not connect with Fedora using it, only with SLAX. Anyhow the Makefile had EXTRA_CFLAGS += ???? and changing it to EXTRA_CPPFLAGS += ????

fixed it for me. Give it a try and report back.

-EXTRA_CFLAGS += -DKMARTIAN_STAMP=20061202
+EXTRA_CPPFLAGS += -DKMARTIAN_STAMP=20061202

HTH,

Antonio

The tar file contains an install script that uses make but,

while I can read the make file, I'm a relative newby when it comes to modules so any insight will be helpful.

Thanks,

So somehow, it still thinks it has and old kernel. Maybe a 'make clean".?

Thanks for your assistance.
