* Merge pull request #2501 from mtrmac/fixed-hook-orderOpenShift Merge Robot2019-04-14
|\ | | | | RFC: Make hooks sort order locale-independent
| * Potentially breaking: Make hooks sort order locale-independentMiloslav Trmač2019-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't sort OCI hooks using the locale collation order; it does not make sense for the same system-wide directory to be interpreted differently depending on the user's LC_COLLATE setting, and the language-specific collation order can even change over time. Besides, the current collation order determination code has never worked with the most common LC_COLLATE values like en_US.UTF-8. Ideally, we would like to just order based on Unicode code points to be reliably stable, but the existing implementation is case-insensitive, so we are forced to rely on the unicode case mapping tables at least. (This gives up on canonicalization and width-insensitivity, potentially breaking users who rely on these previously documented properties.) Signed-off-by: Miloslav Trmač <mitr@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | The SELinux label for the CRIU dump.log was explicitly set in Podman. The label for the restore.log, however, not. This just moves the code to label the log file into a function and calls that functions during checkpoint and restore. Signed-off-by: Adrian Reber <areber@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All IDs in libpod are stored as a full container ID. We can get a container by full ID faster with GetContainer (which directly retrieves) than LookupContainer (which finds a match, then retrieves). No reason to use Lookup when we have full IDs present and available. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'docker commit' will never include a container's volumes when committing, without an explicit request through '--change'. Podman, however, defaulted to including user volumes as image volumes. Make this behavior depend on a new flag, '--include-volumes', and make the default behavior match Docker.

| * | | userns: prevent /sys/kernel/* paths in the containerGiuseppe Scrivano2019-04-11
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when we run in a user namespace, there are cases where we have not enough privileges to mount a fresh sysfs on /sys. To circumvent this limitation, we rbind /sys from the host. This carries inside of the container also some mounts we probably don't want to. We are also limited by the kernel to use rbind instead of bind, as allowing a bind would uncover paths that were not previously visible. This is a slimmed down version of the intermediate mount namespace logic we had before, where we only set /sys to slave, so the umounts done to the storage by the cleanup process are propagated back to the host. We also don't setup any new directory, so there is no additional cleanup to do. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* | Fix E2E testsMatthew Heon2019-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Commit test is blatantly wrong and testing buggy behavior. We should be commiting the destination, if anything - and more likely nothing at all. When force-removing volumes, don't remove the volumes of containers we need to remove. This can lead to a chicken and the egg problem where the container removes the volume before we can. When we re-add volume locks this could lead to deadlocks. I don't really want to deal with this, and this doesn't seem a particularly harmful quirk, so we'll let this slide until we get a bug report. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | Now that named volumes must be explicitly enumerated rather than passed in with all other volumes, we need to split normal and named volumes up before passing them into libpod. This PR does this. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* | Switch Libpod over to new explicit named volumesMatthew Heon2019-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | This swaps the previous handling (parse all volume mounts on the container and look for ones that might refer to named volumes) for the new, explicit named volume lists stored per-container. It also deprecates force-removing volumes that are in use. I don't know how we want to handle this yet, but leaving containers that depend on a volume that no longer exists is definitely not correct.

| * 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>

There's no reason we have to do this, we're just going through it to get field names with reflect, so just make a new copy of the struct in question. Also, move this code, which is only for CLI display, into cmd/podman from libpod/image. Signed-off-by: Matthew Heon <mheon@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | Currently in rootless containers, we end up not using the blob cache. We also don't store the blob cache based on the users specified graph storage. This change will cause the cache directory to be stored with the rest of the containe images. While doing this patch, I found that we had duplicated GetSystemContext in two places in libpod.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have an issue in the current implementation where the cleanup process is not able to umount the storage as it is running in a separate namespace. Simplify the implementation for user namespaces by not using an intermediate mount namespace. For doing it, we need to relax the permissions on the parent directories and allow browsing them. Containers that are running without a user namespace, will still maintain mode 0700 on their directory. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
