[Buildroot] [PATCH v2 0/3] Upgrade systemd to v255

[Buildroot] [PATCH v2 0/3] Upgrade systemd to v255

[Jarkko Sakkinen]

The goal here is to upgrade systemd version to v255, which is the final
version version with sysvinit compatibility. I also cherry-picked couple of
bug fixes from the systemd upstream, which address errors complaining of
missing superblocks:

1. Filesystem found in kernel header but not in \
   filesystems-gperf.gperf: BCACHEFS_SUPER_MAGIC
1. Filesystem found in kernel header but not in \
   filesystems-gperf.gperf: PID_FS_MAGIC

On feature side v255 has a nice tool called 'systemd-pcrlock', which can
be used for creating and experimenting with TPM2 authorization policies,
which is very useful.

I also upgraded tpm2-tools to 5.7 because it has a useful conversion
tool called 'tpm2_encodeobject".

[Buildroot] [PATCH v2 1/3] package/tpm2-tools: bump version to 5.7

[Jarkko Sakkinen]

tpm2_encodeobject is essential for testing RSAPKCS1 and ECDSA TPM2 signing
keys, as the key blob is loaded to the chip in DER format defined by ASN.1
schema.

[Buildroot] [PATCH v2 2/3] package/systemd: bump to version 255

[Jarkko Sakkinen]

The last version with System V init scripts and cgroups v1 support. After
this version the upgrade will take mostly a longer period of time.

[Buildroot] [PATCH v2 3/3] package/systemd: add the missing superblock identifiers

[Jarkko Sakkinen]

The following superblock identifiers are missing:

1. BCACHEFS_SUPER_MAGIC
2. PID_FS_MAGIC

In my testing at least Linux 6.{9,10} have failed to compile because of
this.

Cherry-pick upstream fixes, which address them.

> The following superblock identifiers are missing:

Does that already happen with systemd 254?

  - if yes, then this change should be sent before the version bump:
    first, bug fixes, then new features;
  - if not, then this patch should be included in the patch that does
    the version bump, otherwise the version bump by itself is broken.

Yann E. MORIN.

As far as I know, in Buildroot we do not use that compatibility layer,
as we do pass the followign option at build: -Dsysvinit-path=

So we should not be impacted by that removal, correct?

> and cgroups v1 support.

It's not entirely clear to me how dropping cgroups v1 suport will be
impactful... AFAIK, the kernel has long had cgroups v2, so virtually all
systems where we would deply systemd 256+ would have a recent-enough
kernel.

Did you address the comments above? If so, can you elaborate (even
slightly) in the commit log why nothing changed in those respects,
please?

You forgot to add an "Upstream:" tag:

    https://buildroot.org/downloads/manual/manual.html#_additional_patch_documentation

Applicalble to both bundled patches.
