* Ensure that tmpfs mounts do not have symlinksMatthew Heon2019-03-11
| | | | | | | | | | | | When mounting a tmpfs, runc attempts to make the directory it will be mounted at. Unfortunately, Golang's os.MkdirAll deals very poorly with symlinks being part of the path. I looked into fixing this in runc, but it's honestly much easier to just ensure we don't trigger the issue on our end. Fixes BZ #1686610 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Buffer stdin to a file when importing "-"Nalin Dahyabhai2019-03-11
| | | | | | | | When importing an image from a file somewhere, we already know how to download data from a URL to a file, so do the same for stdin, in case it's unexpectedly large. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>

* Fix generation of infra container commandMatthew Heon2019-03-10
| | | | | | | | | | | | When sourcing from an image, we need to grab its entrypoint first and then add command on to mimic the behavior of Docker. The default Kube pause image just sets ENTRYPOINT, and not CMD, so nothing changes there, but this ought to fix other images (for example, nginx would try to run the pause command instead of an nginx process without this patch) Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Don't delete another container's resolv and hosts filesMatthew Heon2019-03-10
| | | | | | | | | | | The logic of deleting and recreating /etc/hosts and /etc/resolv.conf only makes sense when we're the one that creates the files - when we don't, it just removes them, and there's nothing left to use. Fixes #2602 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Fix a potential segfault during infra container createMatthew Heon2019-03-10

Language tags have the form [1]: language ["-" script] ["-" region] *("-" variant) *("-" extension) ["-" privateuse] and locales have the form [2]: [language[_territory][.codeset][@modifier]] The modifier is useful for collation, but Go's language-based API [3] does not provide a way for us to supply it. This code converts our locale to a BCP 47 language by stripping the dot and later and replacing the first underscore, if any, with a hyphen. This will avoid errors like [4]: WARN[0000] failed to parse language "en_US.UTF-8": language: tag is not well-formed when feeding language.Parse(...).

| * | Change LookupContainer logic to match DockerMatthew Heon2019-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When looking up a container or pod by from user input, we handle collisions between names and IDs differently than Docker at present. In Docker, when there is a container with an ID starting with "c1" and a container named "c1", commands on "c1" will always act on the container named "c1". For the same scenario in podman, we throw an error about name collision. Change Podman to follow Docker, by returning the named container or pod instead of erroring. This should also have a positive effect on performance in the lookup-by-full-name case, which no longer needs to fully traverse the list of all pods or containers.

While inefficient (you add a container for no reason), it shouldn't be a fatal failure.

| | | | | | | | | | | Instead of passing in defaults via WithStorageConfig after computing them in cmd/podman/libpodruntime, do all defaults in libpod itself. This can alleviate ordering issues which caused settings in the libpod config (most notably, volume path) to be ignored. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | When removing volumes with rm --volumes we want to only remove volumes that were created with the container.

| | | | | | | | | | | | | | | We want named volumes to be created in a subdirectory of the c/storage graph root, the same as the libpod root directory is now. As such, we need to adjust its location when the graph root changes location. Also, make a change to how we set the default. There's no need to explicitly set it every time we initialize via an option - that might conflict with WithStorageConfig setting it based on graph root changes. Instead, just initialize it in the default config like our other settings. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

|\ | | | | Fix one (of two) SELinux denials during checkpointing
| * Label CRIU log files correctlyAdrian Reber2019-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRIU creates a log file during checkpointing in .../userdata/dump.log. The problem with this file is, is that CRIU injects a parasite code into the container processes and this parasite code also writes to the same log file. At this point a process from the inside of the container is trying to access the log file on the outside of the container and SELinux prohibits this. To enable writing to the log file from the injected parasite code, this commit creates an empty log file and labels the log file with c.MountLabel(). CRIU uses existing files when writing it logs so the log file label persists and now, with the correct label, SELinux no longer blocks access to the log file.
