linux-libc-dev: Missing headers /usr/include/linux/dn.h and /usr/include/linux/netfilter_decnet.h

[velmafia]

Hi,
In linux-libc-dev package in focal (5.4.0-167.184), two headers file are missing:
- /usr/include/linux/dn.h
- /usr/include/linux/netfilter_decnet.h

In older package version (5.4.0-26.30) available in focal, headers are present.

This files are listed in packages.ubuntu.com: https://packages.ubuntu.com/en/focal/amd64/linux-libc-dev/filelist, but not exist in deb package. Also "searching by filename" show that this file should be part of linux-libc-dev package: https://packages.ubuntu.com/search?searchon=contents&keywords=dn.h&mode=exactfilename&suite=focal&arch=any

Problem exist also in jammy 5.15.0-89.99, but here the difference between the file list and the real package contents is greater: 3 file was added to deb package:
- /usr/include/linux/ipu-isys.h
- /usr/include/linux/ipu-psys.h
- /usr/include/scsi/scsi_bsg_mpi3mr.h
but files are not present in the package file list: https://packages.ubuntu.com/en/jammy/amd64/linux-libc-dev/filelist

I checked two above version for i386 and amd64 arch, but probably problem affected more packages.

OK, I found that this files were moved to linux-libc-dev-<arch>-cross packages.
So currently this is problem with metadata presentation on packages.ubuntu.com.

Second thing:
I found in our internal artifactory cache, that this was changed between 5.4.0-163.180 and 5.4.0-164.181 version (summer 2023). These versions is not longer available in official Ubuntu repository.

I'm not sure if this kind of changes should be delivered to stable repo more than 3 years after focal release.
