* Do not error on installing duplicate shutdown handlerMatthew Heon2020-12-07
| | | | | | | | | | | | | | Installing a duplicate shutdown handler fails, but if a handler with the same name is already present, we should be set to go. There's no reason to print a user-facing error about it. This comes up almost nowhere because Podman never makes more than one Libpod runtime, but there is one exception (`system reset`) and the error messages, while harmless, were making people very confused (we got several bug reports that `system reset` was nonfunctional).

* Drop default log-level from error to warnDaniel J Walsh2020-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our users are missing certain warning messages that would make debugging issues with Podman easier. For example if you do a podman build with a Containerfile that contains the SHELL directive, the Derective is silently ignored. If you run with the log-level warn you get a warning message explainging what happened. $ podman build --no-cache -f /tmp/Containerfile1 /tmp/ STEP 1: FROM ubi8 STEP 2: SHELL ["/bin/bash", "-c"] STEP 3: COMMIT --> 7a207be102a 7a207be102aa8993eceb32802e6ceb9d2603ceed9dee0fee341df63e6300882e $ podman --log-level=warn build --no-cache -f /tmp/Containerfile1 /tmp/ STEP 1: FROM ubi8 STEP 2: SHELL ["/bin/bash", "-c"] STEP 3: COMMIT WARN[0000] SHELL is not supported for OCI image format, [/bin/bash -c] will be ignored.

* Use Libpod tmpdir for pause pathMatthew Heon2020-12-02
| | | | | | | | | | | | | | | | | | | | | Previously, we always computed pause path from the Rootless runtime directory. Problem: this does not match the behavior of Libpod when the directory changes. Libpod will continue to use the previous directory, cached in the database; Pause pidfiles will swap to the new path. This is problematic when the directory needs to exist to write the pidfile, and Libpod is what creates the directory. There are two potential solutions - allow the pause pidfile to move and just make the directory when we want to write it, or use the cached Libpod paths for a guaranteed location. This patch does the second, because it seems safer - we will never miss a previously-existing pidfile because the location is now consistent.

|\ | | | | Fix missing OCI Runtime
| * When given OCI runtime by path, use path as nameMatthew Heon2020-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Say I start a container with the flag `--runtime /usr/local/sbin/crun`. I then stop the container, and restart it without the flag. We previously stored the runtime in use by a container only by basename when given a path, so the container only knows that it's using the `crun` OCI runtime - and on being restarted without the flag, it will use the system crun, not my special crun build. Using the full path as the name in these cases ensures we will still use the correct runtime, even on subsequent runs of Podman. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | Enforce LIFO ordering for shutdown handlersMatthew Heon2020-10-13
| | | | | | | | | | | | | | | | | | | | | | This allows us to run both the Libpod and Server handlers at the same time without unregistering one. Also, pass the signal that killed us into the handlers, in case they want to use it to determine what to do (e.g. what exit code to set). Signed-off-by: Matthew Heon <mheon@redhat.com>
* | Enable masking stop signals within container creationMatthew Heon2020-10-12
|/ | | | | | | | | | | | | | | | | Expand the use of the Shutdown package such that we now use it to handle signals any time we run Libpod. From there, add code to container creation to use the Inhibit function to prevent a shutdown from occuring during the critical parts of container creation. We also need to turn off signal handling when --sig-proxy is invoked - we don't want to catch the signals ourselves then, but instead to forward them into the container via the existing sig-proxy handler.

* Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

* Unconditionally retrieve pod names via APIMatthew Heon2020-08-10
| | | | | | | | | | | | | | | | | | The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.

* Remove all instances of named return "err" from LibpodMatthew Heon2020-07-09
| | | | | | | | | | | | | | | | | This was inspired by https://github.com/cri-o/cri-o/pull/3934 and much of the logic for it is contained there. However, in brief, a named return called "err" can cause lots of code confusion and encourages using the wrong err variable in defer statements, which can make them work incorrectly. Using a separate name which is not used elsewhere makes it very clear what the defer should be doing. As part of this, remove a large number of named returns that were not used anywhere. Most of them were once needed, but are no longer necessary after previous refactors (but were accidentally retained). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules.

* compat handlers: add X-Registry-Auth header supportValentin Rothberg2020-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Support the `X-Registry-Auth` http-request header. * The content of the header is a base64 encoded JSON payload which can either be a single auth config or a map of auth configs (user+pw or token) with the corresponding registries being the keys. Vanilla Docker, projectatomic Docker and the bindings are transparantly supported. * Add a hidden `--registries-conf` flag. Buildah exposes the same flag, mostly for testing purposes. * Do all credential parsing in the client (i.e., `cmd/podman`) pass the username and password in the backend instead of unparsed credentials. * Add a `pkg/auth` which handles most of the heavy lifting. * Go through the authentication-handling code of most commands, bindings and endpoints. Migrate them to the new code and fix issues as seen. A final evaluation and more tests is still required *after* this change. * The manifest-push endpoint is missing certain parameters and should use the ABI function instead. Adding auth-support isn't really possible without these parts working. * The container commands and endpoints (i.e., create and run) have not been changed yet. The APIs don't yet account for the authfile. * Add authentication tests to `pkg/bindings`. Fixes: #6384 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Ensure volumes reacquire locks on state refreshMatthew Heon2019-12-02
| | | | | | | | | | | | | | | | | | | | | | | | After a restart, pods and containers both run a refresh() function to prepare to run after a reboot. Until now, volumes have not had a similar function, because they had no per-boot setup to perform. Unfortunately, this was not noticed when in-memory locking was introduced to volumes. The refresh() routine is, among other things, responsible for ensuring that locks are reserved after a reboot, ensuring they cannot be taken by a freshly-created container, pod, or volume. If this reservation is not done, we can end up with two objects using the same lock, potentially needing to lock each other for some operations - classic recipe for deadlocks. Add a refresh() function to volumes to perform lock reservation and ensure it is called as part of overall refresh(). Fixes #4605 Fixes #4621 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
