* Drop LocalVolumes from our the databaseMatthew Heon2019-04-04
| | | | | | | | We were never using it. It's actually a potentially quite sizable field (very expensive to decode an array of structs!). Removing it should do no harm. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Major rework of --volumes-from flagMatthew Heon2019-04-04
| | | | | | | | | | The flag should be substantially more durable, and no longer relies on the create artifact. This should allow it to properly handle our new named volume implementation. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add handling for new named volumes code in pkg/specMatthew Heon2019-04-04
| | | | | | | | | Now that named volumes must be explicitly enumerated rather than passed in with all other volumes, we need to split normal and named volumes up before passing them into libpod. This PR does this. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* rootless: remove SkipStorageSetup()Giuseppe Scrivano2019-04-01
| | | | | | | | in the few places where we care about skipping the storage initialization, we can simply use the process effective UID, instead of relying on a global boolean flag. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Ensure that we make a netns for CNI non-default netsMatthew Heon2019-03-28
| | | | | | | | | | | | | | | | | We accidentally patched this out trying to enable ns:/path/to/ns This should restore the ability to configure nondefault CNI networks with Podman, by ensuring that they request creation of a network namespace. Completely remove the WithNetNS() call when we do use an explicit namespace from a path. We use that call to indicate that a netns is going to be created - there should not be any question about whether it actually does. Fixes #2795 Signed-off-by: Matthew Heon <mheon@redhat.com>
* Remove ulele/deepcopier in favor of JSON deep copyMatthew Heon2019-03-27
| | | | | | | | | | | | | We have a very high performance JSON library that doesn't need to perform code generation. Let's use it instead of our questionably performant, reflection-dependent deep copy library. Most changes because some functions can now return errors. Also converts cmd/podman to use jsoniter, instead of pkg/json, for increased performance. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com> Vendors in fsouza/docker-client, docker/docker and a few more related. Of particular note, changes to the TweakCapabilities() function from docker/docker along with the parse.IDMappingOptions() function from Buildah. Please pay particular attention to the related changes in the call from libpod to those functions during the review. Passes baseline tests.

|/ | | | | | | | | | | | | Currently if you turn on --net=host on a rootless container and have selinux-policy installed in the image, tools running with SELinux will see that the system is SELinux enabled in rootless mode. This patch mounts a tmpfs over /sys/fs/selinux blocking this behaviour. This patch also fixes the fact that if you shared --pid=host we were not masking over certin /proc paths.

* Fix manual detach from containers to not wait for exitMatthew Heon2019-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | At present, when manually detaching from an attached container (using the detach hotkeys, default C-p C-q), Podman will still wait for the container to exit to obtain its exit code (so we can set Podman's exit code to match). This is correct in the case where attach finished because the container exited, but very wrong for the manual detach case. As a result of this, we can no longer guarantee that the cleanup and --rm functions will fire at the end of 'podman run' - we may be exiting before we get that far. Cleanup is easy enough - we swap to unconditionally using the cleanup processes we've used for detached and rootless containers all along. To duplicate --rm we need to also teach 'podman cleanup' to optionally remove containers instead of cleaning them up. (There is an argument for just using 'podman rm' instead of 'podman cleanup --rm', but cleanup does have different semantics given that we only ever expect it to run when the container has just exited. I think it might be useful to keep the two separate for things like 'podman events'...) Signed-off-by: Matthew Heon <mheon@redhat.com>

* rootless: do not override /dev/pts if not neededGiuseppe Scrivano2019-02-06
| | | | | | | | | | when running in rootless mode we were unconditionally overriding /dev/pts to take ride of gid=5. This is not needed when multiple gids are present in the namespace, which is always the case except when running the tests suite with only one mapping. So change it to check how many gids are present before overriding the default mount. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* apparmor: apply default profile at container initializationValentin Rothberg2019-01-09
| | | | | | | | | | | | | | | | | | | Apply the default AppArmor profile at container initialization to cover all possible code paths (i.e., podman-{start,run}) before executing the runtime. This allows moving most of the logic into pkg/apparmor. Also make the loading and application of the default AppArmor profile versio-indepenent by checking for the `libpod-default-` prefix and over-writing the profile in the run-time spec if needed. The intitial run-time spec of the container differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container. To fix that, load the container config from the file system if present and use it to display the data. Fixes: #2107 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* | add container-init supportValentin Rothberg2019-01-04
|/ | | | | | | | | | | | | | | | | | | Add support for executing an init binary as PID 1 in a container to forward signals and reap processes. When the `--init` flag is set for podman-create or podman-run, the init binary is bind-mounted to `/dev/init` in the container and "/dev/init --" is prepended to the container's command. The default base path of the container-init binary is `/usr/libexec/podman` while the default binary is catatonit [1]. This default can be changed permanently via the `init_path` field in the `libpod.conf` configuration file (which is recommended for packaging) or temporarily via the `--init-path` flag of podman-create and podman-run.
