It's from Gentoo commit 5b974a3c903327b37f46a0212bf397ef634a67fd.
None of these modifications are Flatcar-specific. We are trying to upstream them in gentoo/gentoo#31615. When they reach Gentoo, we can move net-misc/openssh to portage-stable.
- Import and update configs for ssh client and daemon from the flatcar/init repository. These configs have now became snippets that the main configuration file will include. - Install a drop-in file for the ssh.socket unit disabling the rate limiting. - Install compatibility symlinks in old ssh config locations that will point to respective files in /usr/share/flatcar/etc. - Make all these actions optional - openssh USE flag needs to be enabled. That way, generic images can pull those changes, while SDK can avoid doing so.

CI passed. The only test that has failed was some nvidia stuff on azure arm64. Looks unrelated. |

Hm, looks like I forgot to actually paste a link to the Jenkins build: http://jenkins.infra.kinvolk.io:8080/job/container/job/packages_all_arches/2610/cldsv/ Currently I'm rerunning image changes jobs with a fix, so I can see the full report. |

The configs were moved to coreos-base/misc-files. In the meantime, update python compatibility and drop unused USE flag and an obsolete README file.
The sshd config provided by this package is now marked as provided for compatibility only - it will be there in case there is still a symlink in /etc pointing to it. The new config snippet will be used by the enable oslogin stuff in the updated coreos-base/oem-gce package in following commits.
This commit updates our Flatcar patch with a code that will install an sshd config snippet instead of editing the main sshd config file if snippets directory exists.
We will be installing an sshd config snippet instead of replacing the whole sshd config. In order to pull this off, we need to make sure that the snippets directory exists and the main sshd config file actually includes the snippets in the directory.
The configs provided by the openssh and Gentoo projects usually keep everything commented out, meaning that the default values will be used. On top of that, they will also include snippets in the snippet directory. As such, start installing the default configs. We only mask a snippet that defines sftp subsystem, because we provide our own config snippet from coreos-base/misc-files that defines it.

This does mainly two changes:
/etc/ssh/ssh{,d}_config.d/. Adapt other packages that were messing with sshd config to start using snippets instead.The openssh ebuild changes are mostly dropping all the third-party high-performance patches that we weren't even using. In Gentoo, these patches were moved to a separate package,
net-misc/openssh-contrib.Fixes flatcar/Flatcar#1062.
