* add pkg/capabilitiesValentin Rothberg2020-02-14
| | | | | | | | | Add pkg/capabibilities to deal with capabilities. The code has been copied from Docker (and attributed with the copyright) but changed significantly to only do what we really need. The code has also been simplified and will perform better due to removed redundancy. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* | Do not copy up when volume is not emptyMatthew Heon2020-02-12
|/ | | | | | | | | | | | | | | | | When Docker performs a copy up, it first verifies that the volume being copied into is empty; thus, for volumes that have been modified elsewhere (e.g. manually copying into then), the copy up will not be performed at all. Duplicate this behavior in Podman by checking if the volume is empty before copying. Furthermore, move setting copyup to false further up. This will prevent a potential race where copy up could happen more than once if Podman was killed after some files had been copied but before the DB was updated. This resolves CVE-2020-1726.

| | | | | | | | | | | | | | | | | | | | | | Instead of the function updating image.InputName (the only reason for it to need an image), have it return the updated value separately.

| | | | | | | | | | | | | | | | | | | | This is not _trivially_ safe because newImage.getLocalImage() modifies newImage.ImageName, but we overwrite that value anyway.

* | Only modify conmon cgroup if we have running containersMatthew Heon2020-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | If there are no running containers - for example, if the pod was just created - the cgroup in question may not exist (under certain circumstances that we're not 100% sure about). However, regardless, we don't need to set a PID limit, as nothing will be making cleanup processes (no running conmon processes), so not changing the cgroup is safe regardless.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current Libpod pkg/spec has become a victim of the better part of three years of development that tied it extremely closely to the current Podman CLI. Defaults are spread across multiple places, there is no easy way to produce a CreateConfig that will actually produce a valid container, and the logic for generating configs has sprawled across at least three packages. This is an initial pass at a package that generates OCI specs that will supersede large parts of the current pkg/spec. The CreateConfig will still exist, but will effectively turn into a parsed CLI. This will be compiled down into the new SpecGenerator struct, which will generate the OCI spec and Libpod create options. The preferred integration point for plugging into Podman's Go API to create containers will be the new CreateConfig, as it's less tied to Podman's command line. CRI-O, for example, will likely tie in here. Signed-off-by: Matthew Heon <mheon@redhat.com>

* Deprecate & remove IsCtrSpecific in favor of IsAnonMatthew Heon2020-01-29
| | | | | | | | | | | | | | | | | | | In Podman 1.6.3, we added support for anonymous volumes - fixing our old, broken support for named volumes that were created with containers. Unfortunately, this reused the database field we used for the old implementation, and toggled volume removal on for `podman run --rm` - so now, we were removing *named* volumes created with older versions of Podman. We can't modify these old volumes in the DB, so the next-safest thing to do is swap to a new field to indicate volumes should be removed. Problem: Volumes created with 1.6.3 and up until this lands, even anonymous volumes, will not be removed. However, this is safer than removing too many volumes, as we were doing before.

* | Add an API for Attach over HTTP APIMatthew Heon2020-01-16
|/ | | | | | | | | | | | | | | | | | | | | | | | | | The new APIv2 branch provides an HTTP-based remote API to Podman. The requirements of this are, unfortunately, incompatible with the existing Attach API. For non-terminal attach, we need append a header to what was copied from the container, to multiplex STDOUT and STDERR; to do this with the old API, we'd need to copy into an intermediate buffer first, to handle the headers. To avoid this, provide a new API to handle all aspects of terminal and non-terminal attach, including closing the hijacked HTTP connection. This might be a bit too specific, but for now, it seems to be the simplest approach. At the same time, add a Resize endpoint. This needs to be a separate endpoint, so our existing channel approach does not work here. I wanted to rework the rest of attach at the same time (some parts of it, particularly how we start the Attach session and how we do resizing, are (in my opinion) handled much better here. That may still be on the table, but I wanted to avoid breaking existing APIs in this already massive change. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
