2021-05-13Fix problem with grouped cgroupsFabricio Voznika
cgroup controllers can be grouped together (e.g. cpu,cpuacct) and that was confusing Cgroup.Install() into thinking that a cgroup directory was created by the caller, when it had being created by another controller that is grouped together. PiperOrigin-RevId: 373661336

2021-05-05Fixes to runsc cgroupsFabricio Voznika
When loading cgroups for another process, `/proc/self` was used in a few places, causing the end state to be a mix of the process and self. This is now fixes to always use the proper `/proc/[pid]` path. Added net_prio and net_cls to the list of optional controllers. This is to allow runsc to execute then these cgroups are disabled as long as there are no net_prio and net_cls limits that need to be applied. Deflake TestMultiContainerEvent.

The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in some places because the following don't seem to have an equivalent in unix package: - syscall.SysProcIDMap - syscall.Credential Updates #214 PiperOrigin-RevId: 361381490

2021-02-02Stub out basic `runsc events --stat` CPU functionalityKevin Krakauer
Because we lack gVisor-internal cgroups, we take the CPU usage of the entire pod and divide it proportionally according to sentry-internal usage stats. This fixes `kubectl top pods`, which gets a pod's CPU usage by summing the usage of its containers. Addresses #172. PiperOrigin-RevId: 355229833

2021-01-26runsc: check for nested cgroup when generating croup pathsDaniel Dao
in nested container, we see paths from host in /proc/self/cgroup, so we need to re-process that path to get a relative path to be used inside the container. Without it, runsc generates ugly paths that may trip other cgroup watchers that expect clean paths. An example of ugly path is: ``` /sys/fs/cgroup/memory/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93/cgroupPath ``` Notice duplication of `docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93` `/proc/1/cgroup` looks like ``` 12:perf_event:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 11:blkio:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 10:freezer:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 9:hugetlb:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 8:devices:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 7:rdma:/ 6:pids:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 5:cpuset:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 4:cpu,cpuacct:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 3:memory:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 2:net_cls,net_prio:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 1:name=systemd:/docker/e383892b29290ae8005d535f2dadc4a583bb354d5bb1ba8c10bf900d92c4db93 0::/system.slice/containerd.service ``` This is not necessary when the parent container was created with cgroup namespace, but that setup is not very common right now.

2019-12-15Set CPU number to CPU quotaAleksandr Razumov
When application is not cgroups-aware, it can spawn excessive threads which often defaults to CPU number. Introduce a opt-in flag that will set CPU number accordingly to CPU quota (if available). Fixes #1391
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.
