* Add buildah version and distribution to infobaude2018-09-28
| | | | | | | | For the sake of debug and problem reporting, we would benefit from knowing what buildah version was vendored into podman. Also, knowing the distribution and distribution version would also be handy. Signed-off-by: baude <bbaude@redhat.com>

* Refactor Wait() to not require a timeoutMatthew Heon2018-09-21
| | | | | | | | | | | We added a timeout for convenience, but most invocations don't care about it. Refactor it into WaitWithTimeout() and add a Wait() that doesn't require a timeout and uses the default. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1527 Approved by: mheon

* rootless: error out if there are not enough UIDs/GIDs availableGiuseppe Scrivano2018-09-21

* Add new field to libpod to indicate whether or not to use labellingDaniel J Walsh2018-09-20
| | | | | | | | | | | | | | | Also update some missing fields libpod.conf obtions in man pages. Fix sort order of security options and add a note about disabling labeling. When a process requests a new label. libpod needs to reserve all labels to make sure that their are no conflicts. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #1406 Approved by: mheon

* 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.

* 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
* Replace existing iptables handler with firewall codeMatthew Heon2018-09-10
| | | | | | | | | | | | Use the new firewall code vendored from CNI to replace the existing iptables rule addition handler we had in place. This adds proper support for firewalld and should be much better at interacting with the firewall. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1431 Approved by: baude
* Vendor CNI plugins firewall codeMatthew Heon2018-09-10
| | | | | | | | | | | | | | The upstream CNI project has a PR open for adding iptables and firewalld support, but this has been stalled for the better part of a year upstream. On advice of several maintainers, we are vendoring this code into libpod, to perform the relevant firewall configuration ourselves.

* 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.

* rootless: exec handle processes that create an user namespaceGiuseppe Scrivano2018-08-26
| | | | | | | | | | | | | | Manage the case where the main process of the container creates and joins a new user namespace.

* rootless: fix execGiuseppe Scrivano2018-08-26
| | | | | | | | | | | | | | | | | | | | | We cannot re-exec into a new user namespace to gain privileges and access an existing as the new namespace is not the owner of the existing container. "unshare" is used to join the user namespace of the target container. The current implementation assumes that the main process of the container didn't create a new user namespace. Since in the setup phase we are not running with euid=0, we must skip the setup for containers/storage.

* Changed GetContainerStats to return ErrCtrStateInvalidhaircommander2018-08-23
| | | | | | | | | | | | | | This results in some functionality changes: If a ErrCtrStateInvalid is returned to GetPodStats, the container is ommitted from the stats. As such, if an empty slice of Container stats are returned to GetPodStats in varlink, an error will occur. GetContainerStats will return the ErrCtrStateInvalid as well. Finally, if ErrCtrStateInvalid is returned to the podman stats call, the container will be ommitted from the stats. Signed-off-by: haircommander <pehunt@redhat.com> Closes: #1319 Approved by: baude
