* | | Replace tab with spaces in MarshalIndent in libpodMatthew Heon2019-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | The json-iterator package will panic on attempting to use MarshalIndent with a non-space indentation. This is sort of silly but swapping from tabs to spaces is not a big issue for us, so let's work around the silly panic. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | If we are not able to make arbitrary changes to the RLIMIT_NOFILE when lacking CAP_SYS_RESOURCE, don't fail but bump the limit to the maximum allowed. In this way the same code path works with rootless mode. Closes: https://github.com/containers/libpod/issues/2123 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

|\ \ | |/ |/| apparmor: apply default profile at container initialization
| * 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differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container.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>

|\ | | | | Use existing interface to request IP address during restore
| * Use existing interface to request IP address during restoreAdrian Reber2019-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial implementation to request the same IP address for a container during a restore was based on environment variables influencing CNI. With this commit the IP address selection switches to Podman's internal static IP API. This commit does a comment change in libpod/container_easyjson.go to avoid unnecessary re-generation of libpod/container_easyjson.go during build as this fails in CI. The reason for this is that make sees that libpod/container_easyjson.go needs to be re-created. The commit, however, only changes a part of libpod/container.go which is marked as 'ffjson: skip'.

* | hooks: Add pre-create hooks for runtime-config manipulationW. Trevor King2019-01-08
|/ | | | | | | | | | | | | | | | | | | | | | | There's been a lot of discussion over in [1] about how to support the NVIDIA folks and others who want to be able to create devices (possibly after having loaded kernel modules) and bind userspace libraries into the container. Currently that's happening in the middle of runc's create-time mount handling before the container pivots to its new root directory with runc's incorrectly-timed prestart hook trigger [2]. With this commit, we extend hooks with a 'precreate' stage to allow trusted parties to manipulate the config JSON before calling the runtime's 'create'. I'm recycling the existing Hook schema from pkg/hooks for this, because we'll want Timeout for reliability and When to avoid the expense of fork/exec when a given hook does not need to make config changes [3].

| | | | | | | | | | | | | | | | | | | | | | | | | | | Don't initialize the lock manager until almost the end of libpod init, so we can guarantee our tmp dir is properly set up and exists.

* | | When refreshing libpod, if SHM locks exist, remove themMatthew Heon2019-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will hopefully help cases where libpod is initialized multiple times on the same system (as on our CI tests). We still run into potential issues where multiple Podmans with multiple tmp paths try to run on the same system - we could end up thrashing the locks. I think we need a file locks driver for situations like that. We can also see about storing paths in the SHM segment, to make sure multiple libpod instances aren't using the same one.

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.
