These tests verify that podman successfully adds (or fails to add) a connection to an SSH server based on the entries in the `~/.ssh/known_hosts` file. In particular `system connection add` should succeed if: - there is no `know_hosts` file - `known_hosts` has an entry that matches the first protocol/key returned by the SSH server - `known_hosts` has an entry that matches the first protocol/key returned by the SSH server - `known_hosts` has an entry for another SSH server, not for the target server It should fail if the `known_host` file has an entry for the target server that matches the protocol but not the key.

Package [golang.org/x/crypto/ssh/knownhosts](https://pkg.go.dev/golang.org/x/crypto/ssh/knownhosts) has an issue when an SSH server has many public keys (i.e. supports multiple crypto algorithms). For instance, if the local `known_hosts` file entries don't match the first SSH server key but match other keys of the SSH server, the handshake fails with a key mismatch error. See golang/go#29286 and containers/podman#23575. Package [github.com/skeema/knownhosts](https://github.com/skeema/knownhosts) is a wrapper of `x/crypto/ssh/knownhosts` that addresses this issue. This commit replaces the usage of `x/crypto/ssh/knownhosts` in containers/common with `github.com/skeema/knownhosts`. Signed-off-by: Mario Loriedo <[email protected]>

There was a problem hiding this comment.
this seems pointless, why check if the dir already exists. We could also just directly call mkdir and ignore ErrExist there
There was a problem hiding this comment.
Agreed. I just left as it was as it's not doing any harm (except that's hard to read with all those nested conditions...).

TL;DR This PR addresses this issue. In this containers/podman PR, I have added some specific tests.
The package golang.org/x/crypto/ssh/knownhosts has an issue when an SSH server has many public keys (i.e., supports multiple crypto algorithms).
For instance, if the local
known_hostsfile entries don't match the first SSH server key but match other SSH server keys, the handshake fails with a key mismatch error.See golang/go#29286 and containers/podman#23575.
Package github.com/skeema/knownhosts is a wrapper of
x/crypto/ssh/knownhoststhat addresses this issue.This commit replaces the usage of
x/crypto/ssh/knownhostsin containers/common withgithub.aaakk.us.kg/skeema/knownhosts.
