* validate fds --preserve-fdsQi Wang2020-08-04
| | | | | | validate file descriptors passed from podman run and podman exec --preserve-fds. Signed-off-by: Qi Wang <qiwan@redhat.com>
* rootless: do not enable lingering modeGiuseppe Scrivano2019-10-17
| | | | | | | | do not automatically enable lingering mode. Closes: https://github.com/containers/libpod/issues/4224 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* pkg/util: use rootless function to read additional usersGiuseppe Scrivano2019-09-03
| | | | | | | make pkg/rootless.GetConfiguredMappings public so that it can be used from pkg/util. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: detect user namespace configuration changesGiuseppe Scrivano2019-09-03
| | | | | | | | | | | detect if the current user namespace doesn't match the configuration in the /etc/subuid and /etc/subgid files. If there is a mismatch, raise a warning and suggest the user to recreate the user namespace with "system migrate", that also restarts the containers.

* rootless: allow to build without cgoGiuseppe Scrivano2019-07-02
| | | | | | | unfortunately rootless won't work without cgo, as most of the implementation is in C, but at least allow to build libpod. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: enable linger if /run/user/UID not existsGiuseppe Scrivano2019-06-27
| | | | | | | | | | | | | at least on Fedora 30 it creates the /run/user/UID directory for the user logged in via ssh. This needs to be done very early so that every other check when we create the default configuration file will point to the correct location. Closes: https://github.com/containers/libpod/issues/3410 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: make JoinUserAndMountNS privateGiuseppe Scrivano2019-05-25
| | | | | | as it is used only by the rootless package now. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: new function to join existing conmon processesGiuseppe Scrivano2019-05-25
| | | | | | | | | | | | | | | move the logic for joining existing namespaces down to the rootless package. In main_local we still retrieve the list of conmon pid files and use it from the rootless package. In addition, create a temporary user namespace for reading these files, as the unprivileged user might not have enough privileges for reading the conmon pid file, for example when running with a different uidmap and root in the container is different than the rootless user.

* rootless: use a pause processGiuseppe Scrivano2019-05-17
| | | | | | | | | | | | | | | | | use a pause process to keep the user and mount namespace alive. The pause process is created immediately on reload, and all successive Podman processes will refer to it for joining the user&mount namespace. This solves all the race conditions we had on joining the correct namespaces using the conmon processes. As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.

* rootless: use a single user namespaceGiuseppe Scrivano2019-04-01
| | | | | | | | | | | | | | | | | | | | | simplify the rootless implementation to use a single user namespace for all the running containers. This makes the rootless implementation behave more like root Podman, where each container is created in the host environment. There are multiple advantages to it: 1) much simpler implementation as there is only one namespace to join. 2) we can join namespaces owned by different containers. 3) commands like ps won't be limited to what container they can access as previously we either had access to the storage from a new namespace or access to /proc when running from the host. 4) rootless varlink works. 5) there are only two ways to enter in a namespace, either by creating a new one if no containers are running or joining the existing one from any container. Containers created by older Podman versions must be restarted. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: remove SkipStorageSetup()Giuseppe Scrivano2019-04-01
| | | | | | | | in the few places where we care about skipping the storage initialization, we can simply use the process effective UID, instead of relying on a global boolean flag. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Add gating tasksbaude2019-03-13
| | | | | | | | | | | to protect against regressions, we need to add a few gating tasks: * build with varlink * build podman-remote * build podman-remote-darwin we already have a gating task for building without varlink Signed-off-by: baude <bbaude@redhat.com>
* rootless: support a custom arg to the new processGiuseppe Scrivano2019-03-11
| | | | | | | | | let the process running as euid != 0 pass down an argument to the process running in the user namespace. This will be useful for commands like rm -a that needs to join different namespaces, so that we can re-exec separately for each of them. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* 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. In this case we want to join only the first child in the new hierarchy, which is the user namespace that was used to create the container. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com> Closes: #1331 Approved by: rhatdan
* 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.

* more changes to compile darwinbaude2018-07-05
| | | | | | | | | | | | | | | | this should represent the last major changes to get darwin to **compile**. again, the purpose here is to get darwin to compile so that we can eventually implement a ci task that would protect against regressions for darwin compilation. i have left the manual darwin compilation largely static still and in fact now only interject (manually) two build tags to assist with the build. trevor king has great ideas on how to make this better and i will defer final implementation of those to him.
