[Bug 1794346] Re: check and fix zkey required kernel modules locations in debs, udebs, and initramfs

[Seth Forshee]

I've updated the crypto-modules list to include these modules in the
udeb.

As far as unifying the udebs and linux-modules packages, the udeb lists
are in a format specified by kernel-wedge that afaict does not allow
wildcards. Possibly we could add some tooling around all of it to
automatically generate or update the udeb lists. We may be able to look
into that but it's definitely not going to happen for cosmic.

Title:
  check and fix zkey required kernel modules locations in debs, udebs,
  and initramfs

Status in linux package in Ubuntu:
  Triaged
Status in s390-tools package in Ubuntu:
  Fix Committed

Bug description:
  todo: check that these modules are included in the initramfs as well.

  === linux crypto-modules udeb task ==
  linux-modules-4.18.0-8-generic has:
  ./lib/modules/4.18.0-8-generic/kernel/arch/s390/crypto/paes_s390.ko
  ./lib/modules/4.18.0-8-generic/kernel/drivers/s390/crypto/pkey.ko
  ./lib/modules/4.18.0-8-generic/kernel/drivers/s390/crypto/zcrypt.ko
  ./lib/modules/4.18.0-8-generic/kernel/drivers/s390/crypto/zcrypt_cex2a.ko
  ./lib/modules/4.18.0-8-generic/kernel/drivers/s390/crypto/zcrypt_cex4.ko
  ./lib/modules/4.18.0-8-generic/kernel/drivers/s390/crypto/zcrypt_pcixcc.ko

  All of the above appear to be missing from the crypto-modules-4.18.0-8
  -generic-di, please ship them in crypto-modules udeb.

  To avoid discrepancies as to what crypto is supported by the installed
  system, versus d-i environment, it would be nice to make udebs and
  linux-modules packages roughly the same.

  Does it at all make sense to ship matching set of kernel/{arch,drivers}/s390/crypto/*.ko in crypto-modules udeb, as shilled in linux-modules deb?
