* Don't fail if /etc/passwd or /etc/group does not existsDaniel J Walsh2018-11-07
| | | | | | | | | | | Container images can be created without passwd or group file, currently if one of these containers gets run with a --user flag the container blows up complaining about t a missing /etc/passwd file. We just need to check if the error on read is ENOEXIST then allow the read to return, not fail. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| * rootless: do not add an additional /run to runrootGiuseppe Scrivano2018-10-31
| | | | | | | | | | | | | | | | | | we are currently using something like /run/user/UID/run as runroot, as it is already done by Buildah. This ends up with /run/user/UID/run/runc for the runc directory. Change to drop the additional /run so that runc will use /run/user/UID/runc. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

| * get user and group information using securejoin and runc's user librarybaude2018-10-29
| | | | | | | | | | | | | | | | | | | | | | for the purposes of performance and security, we use securejoin to contstruct the root fs's path so that symlinks are what they appear to be and no pointing to something naughty. then instead of chrooting to parse /etc/passwd|/etc/group, we now use the runc user/group methods which saves us quite a bit of performance.

* 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>

| * | rootless: fix an hang on older versions of setresuid/setresgidGiuseppe Scrivano2018-10-11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the issue is caused by the Go Runtime that messes up with the process signals, overriding SIGSETXID and SIGCANCEL which are used internally by glibc. They are used to inform all the threads to update their stored uid/gid information. This causes a hang on the set*id glibc wrappers since the handler installed by glibc is never invoked. Since we are running with only one thread, we don't really need to update other threads or even the current thread as we are not using getuid/getgid before the execvp.

* Drop libnetwork vendor and move the code into pkg/Matthew Heon2018-10-04
| | | | | | | | | | | The vendoring issues with libnetwork were significant (it was dragging in massive amounts of code) and were just not worth spending the time to work through. Highly unlikely we'll ever end up needing to update this code, so move it directly into pkg/ so we don't need to vendor libnetwork. Make a few small changes to remove the need for the remainder of libnetwork. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

* | Add ContainerStateExited and OCI delete() in cleanup()Matthew Heon2018-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To work better with Kata containers, we need to delete() from the OCI runtime as a part of cleanup, to ensure resources aren't retained longer than they need to be. To enable this, we need to add a new state to containers, ContainerStateExited. Containers transition from ContainerStateStopped to ContainerStateExited via cleanupRuntime which is invoked as part of cleanup(). A container in the Exited state is identical to Stopped, except it has been removed from the OCI runtime and thus will be handled differently when initializing the container.

* Pass on securityOpts from podInfraContainer to container added to pod.Daniel J Walsh2018-09-11
| | | | | | | | | | This is an incomplete fix, as it would be best for the libpod library to be in charge of coordinating the container's dependencies on the infra container. A TODO was left as such. UTS is a special case, because the docker library that namespace handling is based off of doesn't recognize a UTS based on another container as valid, despite the library being able to handle it correctly. Thus, it is left in the old way. Signed-off-by: haircommander <pehunt@redhat.com> Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #1347 Approved by: mheon
