Ticket 3674

Hi there. 

Just installed Slurm 17.02.2 and tested the slurm_pam_adopt module. It compiles,  loads and work fine, but it doesn't put the adopted processes in all the configured cgroups. 

During my tests, it correctly put the SSH adopted process in the "cpuset" and "freezer" subsystems, but misses "devices", "cpuacct" and "memory".

Illustration:

* Initial job submission:

sh-ln01 $ srun -w sh-101-59 -p test --pty bash
sh-101-59 $ cat /proc/$$/cgroup
11:hugetlb:/
10:freezer:/slurm/uid_215845/job_11354/step_0
9:memory:/slurm/uid_215845/job_11354/step_0
8:cpuacct,cpu:/slurm/uid_215845/job_11354/step_0/task_0
7:blkio:/
6:devices:/slurm/uid_215845/job_11354/step_0
5:pids:/
4:cpuset:/slurm/uid_215845/job_11354/step_0
3:net_prio,net_cls:/
2:perf_event:/
1:name=systemd:/system.slice/slurmd.service
[kilian@sh-101-59 ~]$


* SSH'ing to the node:

sh-ln01 $ ssh sh-101-59
sh-101-59 $ cat /proc/$$/cgroup
11:hugetlb:/
10:freezer:/slurm/uid_215845/job_11354/step_extern
9:memory:/
8:cpuacct,cpu:/
7:blkio:/
6:devices:/
5:pids:/
4:cpuset:/slurm/uid_215845/job_11354/step_extern
3:net_prio,net_cls:/
2:perf_event:/
1:name=systemd:/user.slice/user-215845.slice/session-2724.scope


And I can confirm that the shell from the SSH process is confined to the CPUs allocated to the job, but it can freely consume all the memory it wants.


We have the following config:

JobAcctGatherType       = jobacct_gather/cgroup
ProctrackType           = proctrack/cgroup
TaskPlugin              = task/cgroup
PrologFlags             = Alloc,Contain


Thanks!
