* Fix conmon attach socket buffer sizePaul Holzinger2021-09-09
| | | | | | | | | | | | | | | The conmon buffer size is 8192, however the attach socket needs two extra bytes. The first byte of each message will be the STREAM type. The last byte is a null byte. So when we want to read 8192 message bytes we need to read 8193 bytes since the first one is special. check https://github.com/containers/conmon/blob/1ef246896b4f6566964ed861b98cd32d0e7bf7a2/src/ctr_stdio.c#L101-L107 This problem can be seen in podman-remote run/exec when it prints output with 8192 or more bytes. The output will miss the 8192 byte. Fixes #11496 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern <cdoern@redhat.com>

The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, Podman would unconditionally remove volumes from the DB, even if they failed to be removed from the volume plugin; this was a safety measure to ensure that `volume rm` can always remove a volume from the database, even if the plugin is misbehaving. However, this is a significant deivation from Docker, which refuses to remove if the plugin errors. These errors can be legitimate configuration issues which the user should address before the volume is removed, so Podman should also use this behaviour.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a host uses systemd-resolved but not the resolved stub resolver the following symlinks are created: `/etc/resolv.conf` -> `/run/systemd/resolve/stub-resolv.conf` -> `/run/systemd/resolve/resolv.conf`. Because the code uses filepath.EvalSymlinks we put the new resolv.conf to `/run/systemd/resolve/resolv.conf` but the `/run/systemd/resolve/stub-resolv.conf` link does not exists in the mount ns. To fix this we will walk the symlinks manually until we reach the first one under `/run` and use this for the resolv.conf file destination.
