From 660a06f2f79fc1edf68e286ee452ceb9dcd5e03a Mon Sep 17 00:00:00 2001 From: Giuseppe Scrivano Date: Wed, 10 Feb 2021 14:46:08 +0100 Subject: utils: takes the longest path on cgroup v1 now getCgroupProcess takes the longest path on cgroup v1, instead of complaining if the paths are different. This should help when --cgroups=split is used on cgroup v1 and the process cgroups look like: $ cat /proc/self/cgroup 11:pids:/user.slice/user-0.slice/session-4.scope 10:blkio:/ 9:cpuset:/ 8:devices:/user.slice 7:freezer:/ 6:memory:/user.slice/user-0.slice/session-4.scope 5:net_cls,net_prio:/ 4:hugetlb:/ 3:cpu,cpuacct:/ 2:perf_event:/ Signed-off-by: Giuseppe Scrivano --- utils/utils_supported.go | 11 ++--------- 1 file changed, 2 insertions(+), 9 deletions(-) (limited to 'utils') diff --git a/utils/utils_supported.go b/utils/utils_supported.go index 7a0417c6c..73313cf5e 100644 --- a/utils/utils_supported.go +++ b/utils/utils_supported.go @@ -81,16 +81,9 @@ func getCgroupProcess(procFile string) (string, error) { cgroup = line[3:] break } - // root cgroup, skip it - if parts[2] == "/" { - continue - } - // The process must have the same cgroup path for all controllers - // The OCI runtime spec file allow us to specify only one path. - if cgroup != "/" && cgroup != parts[2] { - return "", errors.Errorf("cgroup configuration not supported, the process is in two different cgroups") + if len(parts[2]) > len(cgroup) { + cgroup = parts[2] } - cgroup = parts[2] } if cgroup == "/" { return "", errors.Errorf("could not find cgroup mount in %q", procFile) -- cgit v1.2.3-54-g00ecf
