2019-10-01Prevent CAP_NET_RAW from appearing in execFabricio Voznika
'docker exec' was getting CAP_NET_RAW even when --net-raw=false because it was not filtered out from when copying container's capabilities. PiperOrigin-RevId: 272260451
2019-09-27bazel: use rules_pkg from https://github.com/bazelbuild/Andrei Vagin
BUILD:85:1: in _pkg_deb rule //runsc:runsc-debian: target '//runsc:runsc-debian' depends on deprecated target '@bazel_tools//tools/build_defs/pkg:make_deb': The internal version of make_deb is deprecated. Please use the replacement for pkg_deb from https://github.com/bazelbuild/rules_pkg/blob/master/pkg. PiperOrigin-RevId: 271590386

2019-09-23Always set HOME env var with `runsc exec`.Nicolas Lacasse
We already do this for `runsc run`, but need to do the same for `runsc exec`. PiperOrigin-RevId: 270793459

2019-09-19Fix documentation, clean up seccomp filter installation, rename helpers.Robert Tonic
Filter installation has been streamlined and functions renamed. Documentation has been fixed to be standards compliant, and missing documentation added. gofmt has also been applied to modified files.
2019-09-19Place the host UDS mounting behind --fsgofer-host-uds-allowed.Robert Tonic
This commit allows the use of the `--fsgofer-host-uds-allowed` flag to enable mounting sockets and add the appropriate seccomp filters.
2019-09-18Shard the runtime tests.Nicolas Lacasse
Default of 20 shards was arbitrary and will need fine-tuning in later CLs. PiperOrigin-RevId: 269922871

2019-09-10Fix `runsc --version` and add a test.Nicolas Lacasse
We need to include the `--stamp` flag in `tools/workspace_status.sh` for the version to be picked up by the linker. Not sure why. Also changes the VERSION string to STABLE_VERSION, which will cause the program to be re-linked if the string changes. Fixes #830

2019-09-05Ignore the root container when calculating oom_score_adj for the sandbox.Ian Lewis
This is done because the root container for CRI is the infrastructure (pause) container and always gets a low oom_score_adj. We do this to ensure that only the oom_score_adj of user containers is used to calculated the sandbox oom_score_adj. Implemented in runsc rather than the containerd shim as it's a bit cleaner to implement here (in the shim it would require overwriting the oomScoreAdj and re-writing out the config.json again). This processing is Kubernetes(CRI) specific but we are currently only supporting CRI for multi-container support anyway. PiperOrigin-RevId: 267507706

2019-09-04Resolve flakes with TestMultiContainerDestroyFabricio Voznika
Some processes are reparented to the root container depending on the kill order and the root container would not reap in time. So some zombie processes were still present when the test checked. Fix it by running the second container inside a PID namespace. PiperOrigin-RevId: 267278591
2019-09-03Impose order on test scripts.Adin Scannell
The simple test script has gotten out of control. Shard this script into different pieces and attempt to impose order on overall test structure. This change helps lay some of the foundations for future improvements. * The runsc/test directories are moved into just test/. * The runsc/test/testutil package is split into logical pieces. * The scripts/ directory contains new top-level targets. * Each test is now responsible for building targets it requires. * The install functionality is moved into `runsc` itself for simplicity. * The existing kokoro run_tests.sh file now just calls all (can be split). After this change is merged, I will create multiple distinct workflows for Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today, which should dramatically reduce the time-to-run for the Kokoro tests, and provides a better foundation for further improvements to the infrastructure.

This used to be the case, but regressed after a recent change. Also made a few fixes around it and clean up the code a bit. Closes #720 PiperOrigin-RevId: 265717496

This commit further restricts the seccomp filters required for Gofer access ot Unix Domain Sockets (UDS).
2019-08-27First pass at implementing Unix Domain Socket support. No tests.Robert Tonic
This commit adds support for detecting the socket file type, connecting to a Unix Domain Socket, and providing bidirectional communication (without file descriptor transfer support).

2019-08-08netstack: Don't start endpoint goroutines too soon on restore.Rahat Mahmood
Endpoint protocol goroutines were previously started as part of loading the endpoint. This is potentially too soon, as resources used by these goroutine may not have been loaded. Protocol goroutines may perform meaningful work as soon as they're started (ex: incoming connect) which can cause them to indirectly access resources that haven't been loaded yet. This CL defers resuming all protocol goroutines until the end of restore. PiperOrigin-RevId: 262409429

2019-08-02Stops container if gofer is killedFabricio Voznika
Each gofer now has a goroutine that polls on the FDs used to communicate with the sandbox. The respective gofer is destroyed if any of the FDs is closed. Closes #601 PiperOrigin-RevId: 261383725
2019-08-02Remove kernel.mounts.Nicolas Lacasse
We can get the mount namespace from the CreateProcessArgs in all cases where we need it. This also gets rid of kernel.Destroy method, since the only thing it was doing was DecRefing the mounts. Removing the need to call kernel.SetRootMountNamespace also allowed for some more simplifications in the container fs setup code. PiperOrigin-RevId: 261357060
2019-08-01Set sandbox oom_score_adjIan Lewis
Set /proc/self/oom_score_adj based on oomScoreAdj specified in the OCI bundle. When new containers are added to the sandbox oom_score_adj for the sandbox and all other gofers are adjusted so that oom_score_adj is equal to the lowest oom_score_adj of all containers in the sandbox.
