Title:
make-kpkg strips modules when CONFIG_MODULE_SIG is set, breaking
Please note that after I logged this bug I realised that the issue is
not actually INSTALL_MOD_STRIP as the kernel signs the modules *after*
they are stripped, so the signatures should be OK.
I believe the issue is that *after* doing the module install make-kpkg
then runs objcopy on the modules
** Description changed:
- Problem:
+ After doing a module install make-kpkg runs objcopy on the modules to
+ copy out the debug sections for a debug package. It then uses objcopy
+ to remove those same debug sections (along with the crypto signature of
+ the module) from the ones in the main
Status changed to 'Confirmed' because the bug affects multiple users.
** Changed in: kernel-package (Ubuntu)
Status: New = Confirmed

In fact, I tested this:
modprobe crc7
cat /var/log/syslog | grep Disabling lock
kernel: [ 1209.080510] Disabling lock debugging due to kernel taint
cat /proc/sys/kernel/tainted
2
cat /proc/modules
crc7 1290 0 - Live 0x 0x (F)
** Also affects: kernel-package
This is likely an upstream bug, but looking at its bugreports it doesn't
appear to be maintained any more in Debian. :-(
