* Wire network interface into libpodPaul Holzinger2021-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make use of the new network interface in libpod. This commit contains several breaking changes: - podman network create only outputs the new network name and not file path. - podman network ls shows the network driver instead of the cni version and plugins. - podman network inspect outputs the new network struct and not the cni conflist. - The bindings and libpod api endpoints have been changed to use the new network structure. The container network status is stored in a new field in the state. The status should be received with the new `c.getNetworkStatus`. This will migrate the old status to the new format. Therefore old containers should contine to work correctly in all cases even when network connect/ disconnect is used. New features: - podman network reload keeps the ip and mac for more than one network. - podman container restore keeps the ip and mac for more than one network. - The network create compat endpoint can now use more than one ipam config. The man pages and the swagger doc are updated to reflect the latest changes. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* | 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>

* | | pkg/bindings/images.nTar(): set ownership of build context to 0:0Nalin Dahyabhai2021-09-07
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When attempting to run remote builds, users with UID/GID values that were high enough that they wouldn't be mapped into their default user namespace configurations would see their builds fail when the server attempted to extract the build contexts that they supplied, and failed to set ownership of the build context content to the UID/GID that were originally assigned to them. When archiving the build context at the client, set ownership of everything to 0:0, which we know is always mapped. Both ADD and COPY require that we set the ownership of newly-added content to 0:0 (unless the --chown flag is used), so throwing away the original ownership information doesn't hurt, anyway. As usual, tarballs that we extract as part of ADD aren't going to be affected. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>

* | generate systemd: use --cidfile againValentin Rothberg2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9ac5267 changed the type of the generated systemd units from `forking` to `notify`. It further stopped using `--cidfile` and instead intended systemd to take care of stopping the container, which turned out to be a bad idea. Systemd will send the stop/kill signals to conmon which in turn may exit non-zero, depending on the signal, and ultimately breaking container cleanup. Hence, we need to use --cidfile again and let podman stop and remove the container to make sure that everything's in order. Fixes: #11304 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* | Revert "generate systemd: custom stop signal"Valentin Rothberg2021-08-24

It turns out that letting systemd handle stopping the container is not working as I thought it will. Conmon is receiving the stop/kill signals and may exit non-zero, which in turn lets the systemd service transition into the `failed` state. We need to get back to letting Podman stop the containers and do a partial revert of commit 9ac5267 which removed using --cidfile. Happening in a following commit.

* | generate systemd: custom stop signalValentin Rothberg2021-08-24
|/ | | | | | | | | | | | | | | | | | | Commit 9ac5267598c3 changed the type of the generated systemd units from forking to notify. Parts of these changes was also removing the need to pass any information via the file system (e.g., PIDFILE, container ID). That in turn implies that systemd takes care of stopping the container. By default, systemd first sends a SIGTERM and after a certain timeout, it'll send a SIGKILL. That's pretty much what Podman is doing, unless the container was created with a custom stop signal which is the case when the --stop-signal flag was used or systemd is mounted. Account for that by using systemd's KillSignal option which allows for changing SIGTERM to another signal. Also make sure that we're using the correct timeout for units generated with --new.

* Implement SD-NOTIFY proxy in conmonDaniel J Walsh2021-08-20
| | | | | | | | | | | | | | | | This leverages conmon's ability to proxy the SD-NOTIFY socket. This prevents locking caused by OCI runtime blocking, waiting for SD-NOTIFY messages, and instead passes the messages directly up to the host. NOTE: Also re-enable the auto-update tests which has been disabled due to flakiness. With this change, Podman properly integrates into systemd.

* Fix rootless cni dns without systemd stub resolverPaul Holzinger2021-08-16
| | | | | | | | | | | | | | | | | 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. This fixes a regression which was introduced in e73d4829900c. Fixes #11222 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* auto-update: simple rollbackValentin Rothberg2021-08-05
| | | | | | | | | | | | | | | | | | | Add support for simple rollbacks during `podman auto-update`. Rollbacks are enabled by default. If a systemd unit cannot be restarted after an update, the previous image will be retagged and the unit will be restarted a second time. Add system tests for rollbacks. Also fix a bug in the restart sequence; we have to use the channel to actually know whether the restart was successful or not. NOTE: To make rollbacks really useful, users must run their containers with `--sdnotify=container` such that the containers send the ready message over the (mounted) socket. This way, restarting the systemd units during auto update will block until the message has been received (or a timeout kicked in). Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* podman info: try qfile before equeryEd Santiago2021-08-03
| | | | | | | | | | | | | | | | | | podman info takes >20s on Gentoo, because equery is s..l..o..w. qfile is much faster and, I suspect, present in most Gentoo installations, so let's try it first. And, because packageVersion() was scarily unmaintainable, refactor it. Define a simple (string) list of packaging tools to query (rpm, dpkg, ...) and iterate until we find one that works. IMPORTANT NOTE: the Debian (and, presumably, Ubuntu) query does not include version number! There is no standard way on Debian to get a package version from a file path, you can only do it via pipes of chained commands, and I have no desire to implement that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rootlessport forwarder requires a child IP to be set. This must be a valid ip in the container network namespace. The problem is that after a network disconnect and connect the eth0 ip changed. Therefore the packages are dropped since the source ip does no longer exists in the netns. One solution is to set the child IP to 127.0.0.1, however this is a security problem. [1] To fix this we have to recreate the ports after network connect and disconnect. To make this work the rootlessport process exposes a socket where podman network connect/disconnect connect to and send to new child IP to rootlessport. The rootlessport process will remove all ports and recreate them with the new correct child IP. Also bump rootlesskit to v0.14.3 to fix a race with RemovePort().
