Any chance to backport #32224 to V255?

[Cody-Learner]

systemd version in use

Arch testing repo versions:
systemd 255.5-2
systemd-libs 255.5-2

Used distribution

Arch

CPU architectures issue was seen on

x86_64

Component

systemd-vmspawn

Is your feature request related to a problem? Please describe

$ mkosi -d arch -p systemd -p linux --autologin -o image.raw -f build
$ systemd-vmspawn --image=image.raw

Running: systemd-vmspawn --image=image.raw results in the following error:

Using vsock-stream:2:118463064
systemd-vmspawn error !!!! IA32 Exception Type - 0E(#PF - Page-Fault) CPU Apic ID - 00000000 !!!!
....

Describe the solution you'd like

Seems there is a fix that was applied to the 256 version. systemd/systemd#32224

I'd be cool to see the fix applied to 255 if possible, not taking into account when 256 may be available in the Arch testing repos.

Describe alternatives you've considered

Waiting for 256 to hit Arch testing would be the alternative.

The systemd version you checked that didn't have the feature you are asking for

255.5-2

I installed the AUR systemd-git package that provided the following packages:

$ systemctl --version systemd 256~rc1 (meson.version.r73257.132f6cfcfe-1-arch-g132f6cf^) +PAM +AUDIT -SELINUX -APPARMOR -IMA +SMACK +SECCOMP +GCRYPT +GNUTLS +OPENSSL +ACL +BLKID +CURL +ELFUTILS +FIDO2 +IDN2 -IDN +IPTC +KMOD +LIBCRYPTSETUP +LIBCRYPTSETUP_PLUGINS +LIBFDISK +PCRE2 -PWQUALITY +P11KIT -QRENCODE +TPM2 +BZIP2 +LZ4 +XZ +ZLIB +ZSTD +BPF_FRAMEWORK +XKBCOMMON +UTMP -SYSVINIT +LIBARCHIVE

systemd-git meson.version.r73257.132f6cfcfe-1
systemd-libs-git meson.version.r73257.132f6cfcfe-1
systemd-resolvconf-git meson.version.r73257.132f6cfcfe-1
systemd-sysvcompat-git meson.version.r73257.132f6cfcfe-1
systemd-ukify-git meson.version.r73257.132f6cfcfe-1

Now systemd-vmspawn works for the Arch image I had created earlier, however there are other issues.

1. I cannot create new images using mkosi due to the systemd-git package menson versions , ie:

$ mkosi -d arch -p systemd -p linux,base,base-devel,nano,wget,sudo,git --autologin -o image.raw -f build
‣ Syncing package manager metadata for default image
:: Synchronizing package databases...
core 123.7 KiB 53.2 KiB/s 00:02 [########################################] 100%

‣ Building default image
‣ Found '/usr/bin/systemd-repart' with version meson.version.r73257.132f6cfcfe-1-arch-g132f6cf^ but version 254 or newer is required to build disk images.
‣ (Use ToolsTree=default to get a newer version of 'systemd-repart'.)

2. I had to remove mkinitcpio to facilitate the install:
   :: systemd-git-meson.version.r73257.132f6cfcfe-1 and mkinitcpio-38.1-1 are in conflict (systemd). Remove mkinitcpio ? [y/N] y

The 2) issue caused me to preinstall 'dracut' to AFAIK, satisfy an initramfs generating tool dependency for/from the linux kernel.

I prefer to stay with mkinitcpio, so will be reverting back to the testing versions of systemd after this brief test. Unfortunately, due to these issues the AUR systemd-git packages aren't a viable option for me.

Unfortunately that patch doesn't apply cleanly, there were a bunch of reworks before it. I'd be happy to take a pull request, but I don't plan to backport it myself.
