the signed template together with the binary package(s) containing the unsigned
files form the input to our secure boot signing service.
the signed template consists of
- files.json (specifying which files are signed how and by which key)
- packaging template used to build the signed package(s)
the signing service
- extracts and checks the signed-template binary package
- extracts the unsigned package(s)
- signs the needed files
- packs up the signatures + the template contained in the signed-template
package into the signed source package
the signed source package can then be built in the regular fashion (in case of
the kernel packages, it will copy the kernel image, modules and some helper
files from the unsigned package, attach the signature created by the signing
service, and re-pack the result as signed-kernel package).

it's really not just ZFS and AMDGPU modules, but way more and
generating scary looking messages for these "issues" is just noise
that drown real issues. Disable this for now, maybe in another few
years.

it's mostly noise for users, and quiet some interpret this as real
problem and report it to us.
Ideally we'd either educate them, or take time ourself, to report this
upstream and see if the situation can be improved overall, but
currently that's not feasible. We should check this out a few releases
down, if the lower hanging fruits got fixed and noise got lower we
could enable it again to catch the more rare cases.

We have a slightly better fix where only a few targeted ZFS module
parts are added to the UBSAN ignore-list, so the rest of the kernel
still gets exposure.

into zfs.ko") we only have two modules to care about.

this is required for secure boot support.
at build time, an ephemeral key pair will be generated and all built modules
will be signed with it. the private key is discarded, and the public key
embedded in the kernel image for signature validation at module load time.
this change means that every kernel release must be considered an ABI change
from now on, else the signatures of on-disk modules and the signing key
embedded in the running kernel image might not match.

long overdue, and avoids the issue of the meta packages version going down
after being folded in from the pve-kernel-meta repository.
the ABI needs to be bumped for every published kernel package now that modules
are signed, else the booted kernel image containing the public part of the
ephemeral signing key, and the on-disk (potentially upgraded in-place) signed
module files can disagree, and module loading would fail.
