* We need to change the SELinux label of the conmon process to s0Daniel J Walsh2018-05-31
| | | | | | | | | | | | | If SELinux is enabled, we are leaking in pipes into the container owned by conmon. The container processes are not allowed to use these pipes, if the calling process is fully ranged. By changing the level of the conmon process to s0, this allows container processes to use the pipes. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #854 Approved by: mheon

* hooks: Order injection by collated JSON filenameW. Trevor King2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | We also considered ordering with sort.Strings, but Matthew rejected that because it uses a byte-by-byte UTF-8 comparison [1] which would fail many language-specific conventions [2]. There's some more discussion of the localeToLanguage mapping in [3]. Currently language.Parse does not handle either 'C' or 'POSIX', returning: und, language: tag is not well-formed for both.

* libpod: Add HooksDirNotExistFatalW. Trevor King2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And add an argument to WithHooksDir to set it. If the hook dir doesn't exist, the new hooks package considers that a fatal error. When a podman caller sets --hooks-dir-path=/some/typoed/directory, a fatal error is more helpful than silently not loading any hooks. However, callers who call podman without setting --hooks-dir-path may not need hooks at all. We don't want to pester those callers with not-exist errors. With this commit, we: * Assume the caller knows what they're doing if they set --hooks-dir-path and set HooksDirNotExistFatal. * If the caller does not explicitly set --hooks-dir-path, assume they won't mind if the hook directory is missing and set HooksDirNotExistFatal false. We also considered checking for the directory's existence in the code calling WithHooksDir or from within WithHooksDir, but checks there would race with the underlying ioutil.ReadDir in the hooks package. By pushing the warn/error decision down into libpod's implementation, we avoid a racy "do we expect this to work once libpod gets to it?" pre-check. I've also added a check to error if WithHooksDir is called with an empty-string argument, because we haven't defined the semantics of that (is it clearing a previous value? Is it effectively the same as the current directory?). I agree with Matthew that a separate WithNoHooks, or a *string argument to WithHooks, or some such would be a better API for clearing previous values [1]. But for now, I'm just erroring out to fail early for callers who might otherwise be surprised that libpod ignores empty-string HooksDir.

* pkg/hooks: Version the hook structure and add 1.0.0 hooksW. Trevor King2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shifts the matching logic out of libpod/container_internal and into the hook package, where we can reuse it after vendoring into CRI-O. It also adds unit tests with almost-complete coverage. Now libpod is even more isolated from the hook internals, which makes it fairly straightforward to bump the hook config file to 1.0.0. I've dubbed the old format 0.1.0, although it doesn't specify an explicit version. Motivation for some of my changes with 1.0.0: * Add an explicit version field. This will make any future JSON structure migrations more straightforward by avoiding the need for version-guessing heuristics. * Collect the matching properties in a new When sub-structure. This makes the root Hook structure easier to understand, because you don't have to read over all the matching properties when wrapping your head around Hook. * Replace the old 'hook' and 'arguments' with a direct embedding of the runtime-spec's hook structure. This provides access to additional upstream properties (args[0], env, and timeout) and avoids the complication of a CRI-O-specific analog structure. * Add a 'when.always' property. You can usually accomplish this effect in another way (e.g. when.commands = [".*"]), but having a boolean explicitly for this use-case makes for easier reading and writing. * Replace the previous annotations array with an annotations map. The 0.1.0 approach matched only the values regardless of key, and that seems unreliable. * Replace 'cmds' with 'when.commands', because while there are a few ways to abbreviate "commands", there's only one way to write it out in full ;). This gives folks one less thing to remember when writing hook JSON. * Replace the old "inject if any specified condition matches" with "inject if all specified conditions match". This allows for more precise targeting. Users that need more generous targeting can recover the previous behavior by creating a separate 1.0.0 hook file for each specified 0.1.0 condition. I've added doc-compat support for the various pluralizations of the 0.1.0 properties. Previously, the docs and code were not in agreement. More on this particular facet in [1]. I've updated the docs to point out that the annotations being matched are the OCI config annotations. This differs from CRI-O, where the annotations used are the Kubernetes-supplied annotations [2,3]. For example, io.kubernetes.cri-o.Volumes [4] is part of CRI-O's runtime config annotations [5], but not part of the Kubernetes-supplied annotations CRI-O uses for matching hooks. The Monitor method supports the CRI-O use-case [6]. podman doesn't need it directly, but CRI-O will need it when we vendor this package there. I've used nvidia-container-runtime-hook for the annotation examples because Dan mentioned the Nvidia folks as the motivation behind annotation matching. The environment variables are documented in [7]. The 0.1.0 hook config, which does not allow for environment variables, only works because runc currently leaks the host environment into the hooks [8]. I haven't been able to find documentation for their usual annotation trigger or hook-install path, so I'm just guessing there.
