LGTM once the tests are hip and @edsantiago 's comments are addressed. |

Need another PR in c/common. I am pretty happy about the test as it's quite helpful in finding (more) issues. |

Commit 97961a6 took a first stab at making operating on the layer tree more resilient by detecting unknown-image errors. Testing in containers/podman/pull/18980 revealed that we also need to detect unknown-layer and -size errors as well. Move the errors checks into a convenience function and update the relevant call sites to facilitate future changes. Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

Now vendoring containers/common#1522 which is needed to address more errors that popped up. I've been running the test for the past 20 mins on my machine but let's see what CI says. |

Testing in containers/podman/pull/18980 revealed that we also need to detect unknown-layer and -size errors as well. Move the errors checks into a convenience function and update the relevant call sites to facilitate future changes. Export the function since Podman needs the very same checks when operating on images, for instance, when looking up image labels. Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

Handle more TOCTOUs operating on listed images. Also pull in containers/common/pull/1520 and containers/common/pull/1522 which do the same on the internal layer tree. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2216700 Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

@vrothberg this is a new (to me) error: Is there any chance your code could've caused this? |
It is not obvious to me but "never say never". Let's keep an eye on it. |
