Description Tim Burke 2003-11-26 11:46:41 EST
Description of problem:
Everyone knows that the kernel binary compat is a big deal in the RHEL
family.  (Well, especially for x86.)  In RHEL2.1 there was a change in
modutils to allow partner supplied kernel modules to load without
requiring the -f option.  That was done because the partners
complained that it would introduce too much support load if usage of
-f was required.

The behavior in RHEL 3 as it stands now should be modified to be
functionally comparable to RHEL2.1.  For example, to compare the major
version only, not the EXTRAVERSION if crcs are present.

Note that there was no change to allow this to work in RHEL2.1; it
just happened to work because of an upstream bug.
Comment 3 Bill Nottingham 2003-11-26 15:29:58 EST
modutils-2.4.25-11.EL will load the modules and print the following:

Warning: kernel-module version mismatch
  loop.o was compiled for kernel version 2.4.21-4.EL
  while this kernel is version 2.4.21-4.17.EL
Warning: loading loop.o will taint the kernel: forced load
 See http://www.tux.org/lkml/#export-tainted for information about
tainted modules
