Hi,
I'd like to come back to this topic. We've discussed this before on IRC
but there's still no acceptable solution implemented.
3rd party kernel-modules are build against the official Red Hat kernels,
to make them work with the TaoLinux/CentOS kernels there are specific
requirements:
+ kernel RPM package should provide the same version/release
+ kernel version/release should be the same for
o /lib/modules/kernel-version-release
o /boot/vmlinuz-version-release
This means there's not much room for customization if you want 3rd party
modules to work. You can have a different version in the RPM as long as
the Red Hat version/release is also provided by the package and the
kernel-files/directories have the exact version/release.
To give you a better understanding of the pitfalls:
| Installing a kernel-module, beware that I already do not require an
| exact version for the kernel RPM package, because that has other
| problems. Still I need to make sure I have an exact kernel and that's
| why we use the vmlinuz file.
[root at breeg root]# rpm -ihvU
kernel-module-openswan-2.4.21-15.0.2.EL-2.1.2-1.1.el3.dag.i586.rpm
error: Failed dependencies:
/boot/vmlinuz-2.4.21-15.0.2.EL is needed by
kernel-module-openswan-2.4.21-15.0.2.EL-2.1.2-1.1.el3.dag
| Loading a module (I --nodeps installed the module), gives the following
| warning. Beware that the module is placed in
| /lib/modules/version-release which is different currently than the one
| from TaoLinux. So people can't just do "modprobe ipsec":
[root at breeg modules]# insmod
/lib/modules/2.4.21-15.0.2.EL/kernel/net/openswan/ipsec.o
Warning: kernel-module version mismatch
2.4.21-15.0.2.EL/kernel/net/openswan/ipsec.o was compiled for kernel
version 2.4.21-15.0.2.EL
while this kernel is version 2.4.21-15.TL2
Warning: loading 2.4.21-15.0.2.EL/kernel/net/openswan/ipsec.o will taint the
kernel: forced load
See http://www.tux.org/lkml/#export-tainted for information about tainted
modules
Module ipsec loaded, with warnings
Although I can make it work like this, this is far from optimal and for
other 3rd party kernel modules this isn't even guaranteed to work.
PS I tried with a CentOS kernel, but I can't seem to find a i586 kernel on
the website.
