| * Fix: Prevent OCI runtime directory remainToshiki Sonoda2022-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was introduced in https://github.com/containers/podman/pull/8906. When we use 'podman rm/restart/stop/kill etc...' command to the container running with --rm, the OCI runtime directory remains at /run/<runtime name> (root user) or /run/user/<user id>/<runtime name> (rootless user). This bug could cause other bugs. For example, when we checkpoint the container running with --rm (podman checkpoint --export) and restore it (podman restore --import) with crun, error message "Error: OCI runtime error: crun: container `<container id>` already exists" is outputted. This error is caused by an attempt to restore the container with the same container ID as the remaining OCI runtime's container ID. Therefore, I fix that the cleanupRuntime() function runs to remove the OCI runtime directory, even if the container has already been removed by --rm option.

* | libpod: fix wait and exit-code logicValentin Rothberg2022-06-23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit addresses three intertwined bugs to fix an issue when using Gitlab runner on Podman. The three bug fixes are not split into separate commits as tests won't pass otherwise; avoidable noise when bisecting future issues. 1) Podman conflated states: even when asking to wait for the `exited` state, Podman returned as soon as a container transitioned to `stopped`. The issues surfaced in Gitlab tests to fail [1] as `conmon`'s buffers have not (yet) been emptied when attaching to a container right after a wait. The race window was extremely narrow, and I only managed to reproduce with the Gitlab runner [1] unit tests. 2) The clearer separation between `exited` and `stopped` revealed a race condition predating the changes. If a container is configured for autoremoval (e.g., via `run --rm`), the "run" process competes with the "cleanup" process running in the background. The window of the race condition was sufficiently large that the "cleanup" process has already removed the container and storage before the "run" process could read the exit code and hence waited indefinitely. Address the exit-code race condition by recording exit codes in the main libpod database. Exit codes can now be read from a database. When waiting for a container to exit, Podman first waits for the container to transition to `exited` and will then query the database for its exit code. Outdated exit codes are pruned during cleanup (i.e., non-performance critical) and when refreshing the database after a reboot. An exit code is considered outdated when it is older than 5 minutes. While the race condition predates this change, the waiting process has apparently always been fast enough in catching the exit code due to issue 1): `exited` and `stopped` were conflated. The waiting process hence caught the exit code after the container transitioned to `stopped` but before it `exited` and got removed. 3) With 1) and 2), Podman is now waiting for a container to properly transition to the `exited` state. Some tests did not pass after 1) and 2) which revealed the third bug: `conmon` was executed with its working directory pointing to the OCI runtime bundle of the container. The changed working directory broke resolving relative paths in the "cleanup" process. The "cleanup" process error'ed before actually cleaning up the container and waiting "main" process ran indefinitely - or until hitting a timeout. Fix the issue by executing `conmon` with the same working directory as Podman. Note that fixing 3) *may* address a number of issues we have seen in the past where for *some* reason cleanup processes did not fire.

* | libpod: store network status when userns is usedPaul Holzinger2022-06-07
|/ | | | | | | | | | | | | | | | | | When a container with a userns is created the network setup is special. Normally the netns is setup before the oci runtime container is created, however with a userns the container is created first and then the network is setup. In the second case we never saved the container state afterwards. Because of it, podman inspect would not show the network info and network teardown will not happen. This worked with local podman because there was a save() call later in the code path which then also saved the network status. But in the podman API code path this save never happened thus all containers started via API had this problem. Fixes #14465 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* pod: add exit policiesValentin Rothberg2022-05-02
| | | | | | | | | | | | | | | | | | | | | | | | Add the notion of an "exit policy" to a pod. This policy controls the behaviour when the last container of pod exits. Initially, there are two policies: - "continue" : the pod continues running. This is the default policy when creating a pod. - "stop" : stop the pod when the last container exits. This is the default behaviour for `play kube`. In order to implement the deferred stop of a pod, add a worker queue to the libpod runtime. The queue will pick up work items and in this case helps resolve dead locks that would otherwise occur if we attempted to stop a pod during container cleanup. Note that the default restart policy of `play kube` is "Always". Hence, in order to really solve #13464, the YAML files must set a custom restart policy; the tests use "OnFailure".

* Add support for checkpoint imageRadostin Stoyanov2022-04-20
| | | | | | | | | | | | | | | | | | | | | | | | This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image <image>` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.

* Added optional container restore statisticsAdrian Reber2021-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the parameter '--print-stats' to 'podman container restore'. With '--print-stats' Podman will measure how long Podman itself, the OCI runtime and CRIU requires to restore a checkpoint and print out these information. CRIU already creates process restore statistics which are just read in addition to the added measurements. In contrast to just printing out the ID of the restored container, Podman will now print out JSON: # podman container restore --latest --print-stats { "podman_restore_duration": 305871, "container_statistics": [ { "Id": "47b02e1d474b5d5fe917825e91ac653efa757c91e5a81a368d771a78f6b5ed20", "runtime_restore_duration": 140614, "criu_statistics": { "forking_time": 5, "restore_time": 67672, "pages_restored": 14 } } ] } The output contains 'podman_restore_duration' which contains the number of microseconds Podman required to restore the checkpoint. The output also includes 'runtime_restore_duration' which is the time the runtime needed to restore that specific container. Each container also includes 'criu_statistics' which displays the timing information collected by CRIU. Signed-off-by: Adrian Reber <areber@redhat.com>

So if a users forwards a range of 1k ports with podman run -p 1001-2000 we have to store each of the thousand ports individually as array element. This bloats the db and makes the JSON encoding and decoding much slower. In many places we already use a better port struct type which supports ranges, e.g. `pkg/specgen` or the new network interface. Because of this we have to do many runtime conversions between the two port formats. If everything uses the new format we can skip the runtime conversions. This commit adds logic to replace all occurrences of the old format with the new one. The database will automatically migrate the ports to new format when the container config is read for the first time after the update. The `ParsePortMapping` function is `pkg/specgen/generate` has been reworked to better work with the new format. The new logic is able to deduplicate the given ports. This is necessary the ensure we store them efficiently in the DB. The new code should also be more performant than the old one. To prove that the code is fast enough I added go benchmarks. Parsing 1 million ports took less than 0.5 seconds on my laptop. Benchmark normalize PortMappings in specgen: Please note that the 1 million ports are actually 20x 50k ranges because we cannot have bigger ranges than 65535 ports. ``` $ go test -bench=. -benchmem ./pkg/specgen/generate/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/pkg/specgen/generate cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz BenchmarkParsePortMappingNoPorts-12 480821532 2.230 ns/op 0 B/op 0 allocs/op BenchmarkParsePortMapping1-12 38972 30183 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMapping100-12 18752 60688 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMapping1k-12 3104 331719 ns/op 223840 B/op 3018 allocs/op BenchmarkParsePortMapping10k-12 376 3122930 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMapping1m-12 3 390869926 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingReverse100-12 18940 63414 ns/op 141088 B/op 315 allocs/op BenchmarkParsePortMappingReverse1k-12 3015 362500 ns/op 223841 B/op 3018 allocs/op BenchmarkParsePortMappingReverse10k-12 343 3318135 ns/op 1223650 B/op 30027 allocs/op BenchmarkParsePortMappingReverse1m-12 3 403392469 ns/op 124593840 B/op 4000624 allocs/op BenchmarkParsePortMappingRange1-12 37635 28756 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange100-12 39604 28935 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1k-12 38384 29921 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange10k-12 29479 40381 ns/op 131584 B/op 9 allocs/op BenchmarkParsePortMappingRange1m-12 927 1279369 ns/op 143022 B/op 164 allocs/op PASS ok github.com/containers/podman/v3/pkg/specgen/generate 25.492s ``` Benchmark convert old port format to new one: ``` go test -bench=. -benchmem ./libpod/ goos: linux goarch: amd64 pkg: github.com/containers/podman/v3/libpod cpu: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Benchmark_ocicniPortsToNetTypesPortsNoPorts-12 663526126 1.663 ns/op 0 B/op 0 allocs/op Benchmark_ocicniPortsToNetTypesPorts1-12 7858082 141.9 ns/op 72 B/op 2 allocs/op Benchmark_ocicniPortsToNetTypesPorts10-12 2065347 571.0 ns/op 536 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts100-12 138478 8641 ns/op 4216 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1k-12 9414 120964 ns/op 41080 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts10k-12 781 1490526 ns/op 401528 B/op 4 allocs/op Benchmark_ocicniPortsToNetTypesPorts1m-12 4 250579010 ns/op 40001656 B/op 4 allocs/op PASS ok github.com/containers/podman/v3/libpod 11.727s ``` Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* libpod: do not call (*container).Spec()Valentin Rothberg2021-09-29
| | | | | | | | | | | | Access the container's spec field directly inside of libpod instead of calling Spec() which in turn creates expensive JSON deep copies. Accessing the field directly drops memory consumption of a simple podman run --rm busybox true from ~700kB to ~600kB. [NO TESTS NEEDED] Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* libpod: do not call (*container).Config()Valentin Rothberg2021-09-28
| | | | | | | | | | | | Access the container's config field directly inside of libpod instead of calling `Config()` which in turn creates expensive JSON deep copies. Accessing the field directly drops memory consumption of a simple `podman run --rm busybox true` from 1245kB to 410kB. [NO TESTS NEEDED] Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
