| * Add 'relabel' to --mount optionsDaniel J Walsh2019-09-16
| | | | | | | | | | | | | | | | | | Currently if a user specifies a --mount option, their is no way to tell SELinux to relabel the mount point. This patch addes the relabel=shared and relabel=private options. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Merge pull request #3876 from mheon/fix_mount_flagsOpenShift Merge Robot2019-09-04
|\ | | | | Allow suid, exec, dev mount options to cancel nosuid/noexec/nodev
| * Fix addition of mount options when using RO tmpfsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | For read-only containers set to create tmpfs filesystems over /run and other common destinations, we were incorrectly setting mount options, resulting in duplicate mount options. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Set base mount options for bind mounts from base systemMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I mount, say, /usr/bin into my container - I expect to be able to run the executables in that mount. Unconditionally applying noexec would be a bad idea. Before my patches to change mount options and allow exec/dev/suid being set explicitly, we inferred the mount options from where on the base system the mount originated, and the options it had there. Implement the same functionality for the new option handling. There's a lot of performance left on the table here, but I don't know that this is ever going to take enough time to make it worth optimizing. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Don't double-process tmpfs optionsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | We already process the options on all tmpfs filesystems during final addition of mounts to the spec. We don't need to do it before that in parseVolumes. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Add support for 'exec', 'suid', 'dev' mount flagsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we explicitly set noexec/nosuid/nodev on every mount, with no ability to disable them. The 'mount' command on Linux will accept their inverses without complaint, though - 'noexec' is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support for passing these options at the command line to disable our explicit forcing of security options. This also cleans up mount option handling significantly. We are still parsing options in more than one place, which isn't good, but option parsing for bind and tmpfs mounts has been unified.

| * When populating CMD, do not include EntrypointMatthew Heon2019-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we use CreateConfig's Command to populate container Command (which is used as CMD for Inspect and Commit). Unfortunately, CreateConfig's Command is the container's full command, including a prepend of Entrypoint - so we duplicate Entrypoint for images that include it. Maintain a separate UserCommand in CreateConfig that does not include the entrypoint, and use that instead. Fixes #3708 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to run Podman with VM-based runtimes unprivileged, the network must be set up prior to the container creation.

* Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.

| | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).
