* rootless: propagate errors from infoGiuseppe Scrivano2019-03-08
| | | | | | | | | we use "podman info" to reconfigure the runtime after a reboot, but we don't propagate the error message back if something goes wrong. Closes: https://github.com/containers/libpod/issues/2584 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

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.

| | | | | | | | | | | Instead of passing in defaults via WithStorageConfig after computing them in cmd/podman/libpodruntime, do all defaults in libpod itself.

* When location of c/storage root changes, set VolumePathMatthew Heon2019-02-26
| | | | | | | | | | | | | | | 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.

|\ \ | |/ |/| Add lock renumbering
| * Do not make renumber shut down the runtimeMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original intent behind the requirement was to ensure that, if two SHM lock structs were open at the same time, we should not make such a runtime available to the user, and should clean it up instead. It turns out that we don't even need to open a second SHM lock struct - if we get an error mapping the first one due to a lock count mismatch, we can just delete it, and it cleans itself up when it errors. So there's no reason not to return a valid runtime. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Recreate SHM locks when renumbering on count mismatchMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we're renumbering locks, we're destroying all existing allocations anyways, so destroying the old lock struct is not a particularly big deal. Existing long-lived libpod instances will continue to use the old locks, but that will be solved in a followon. Also, solve an issue with returning error values in the C code. There were a few places where we return ERRNO where it was not set, so make them return actual error codes). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Move RenumberLocks into runtime initMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't do renumbering after init - we need to open a potentially invalid locks file (too many/too few locks), and then potentially delete the old locks and make new ones. We need to be in init to bypass the checks that would otherwise make this impossible. This leaves us with two choices: make RenumberLocks a separate entrypoint from NewRuntime, duplicating a lot of configuration load code (we need to know where the locks live, how many there are, etc) - or modify NewRuntime to allow renumbering during it. Previous experience says the first is not really a viable option and produces massive code bloat, so the second it is. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Remove locks from volumesMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was looking into why we have locks in volumes, and I'm fairly convinced they're unnecessary. We don't have a state whose accesses we need to guard with locks and syncs. The only real purpose for the lock was to prevent concurrent removal of the same volume. Looking at the code, concurrent removal ought to be fine with a bit of reordering - one or the other might fail, but we will successfully evict the volume from the state. Also, remove the 'prune' bool from RemoveVolume. None of our other API functions accept it, and it only served to toggle off more verbose error messages.
