* podman: fix ro bind mounts if no* opts are on the sourceGiuseppe Scrivano2019-02-25
| | | | | | | | | | | | | | This is a workaround for the runc issue: https://github.com/opencontainers/runc/issues/1247 If the source of a bind mount has any of nosuid, noexec or nodev, be sure to propagate them to the bind mount so that when runc tries to remount using MS_RDONLY, these options are also used. Closes: https://github.com/containers/libpod/issues/2312 Signed-off-by: Giuseppe Scrivano <gscrivan@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>
* rootless: fix --pid=host without --privilegedGiuseppe Scrivano2019-01-18
| | | | | | | When using --pid=host don't try to cover /proc paths, as they are coming from the /proc bind mounted from the host. 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differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container.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>
* Update vendor of runcDaniel J Walsh2019-01-04
| | | | | | | | | | | | | | Updating the vendor or runc to pull in some fixes that we need. In order to get this vendor to work, we needed to update the vendor of docker/docker, which causes all sorts of issues, just to fix the docker/pkg/sysinfo. Rather then doing this, I pulled in pkg/sysinfo into libpod and fixed the code locally. I then switched the use of docker/pkg/sysinfo to libpod/pkg/sysinfo. I also switched out the docker/pkg/mount to containers/storage/pkg/mount Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Fixes to handle /dev/shm correctly.Daniel J Walsh2018-12-24
| | | | | | | | | | | | | | | | | | We had two problems with /dev/shm, first, you mount the container read/only then /dev/shm was mounted read/only. This is a bug a tmpfs directory should be read/write within a read-only container. The second problem is we were ignoring users mounted /dev/shm from the host. If user specified podman run -d -v /dev/shm:/dev/shm ... We were dropping this mount and still using the internal mount. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Allow users to specify a directory for additonal devicesDaniel J Walsh2018-12-21
| | | | | | | Podman will search through the directory and will add any device nodes that it finds. If no devices are found we return an error. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Mount proper cgroup for systemd to manage inside of the container.Daniel J Walsh2018-10-15
| | | | | | | | | | | | We are still requiring oci-systemd-hook to be installed in order to run systemd within a container. This patch properly mounts /sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container. Since we need the UUID of the container, we needed to move Systemd to be a config option of the container. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| | | | | | | | | | | | | | | Also update some missing fields libpod.conf obtions in man pages. Fix sort order of security options and add a note about disabling labeling.

* Small updates to OCI spec generationMatthew Heon2018-09-17
| | | | | | | | | | | | | Firstly, when adding the privileged catch-all resource device, first remove the spec's default catch-all resource device. Second, remove our default rootfs propogation config - Docker does not set this by default, so I don't think we should either.

* Respect user-added mounts over default spec mountsMatthew Heon2018-09-07
| | | | | | | | | | | | | | When there was a conflict between a user-added volume and a mount already in the spec, we previously respected the mount already in the spec and discarded the user-added mount. This is counter to expected behavior - if I volume-mount /dev into the container, I epxect it will override the default /dev in the container, and not be ignored.

| | | | | | | | | | | | | | | Do not set any hostname value in the OCI configuration when --uts=host is used and the user didn't specify any value. This prevents an error from the OCI runtime as it cannot set the hostname without a new UTS namespace. Differently, the HOSTNAME environment variable is always set. When --uts=host is used, HOSTNAME gets the value from the host. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com> Closes: #1280 Approved by: baude
