Description Tim Burke 2003-11-26 16:46:41 UTC
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.

Comment 2 Bill Nottingham 2003-11-26 17:29:45 UTC
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 20:29:58 UTC
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
