Kir Kolyshkin 59897367c4 cgroups/systemd: allow to set -1 as pids.limit ... Currently, both systemd cgroup drivers (v1 and v2) only set "TasksMax" unit property if the value > 0, so there is no way to update the limit to -1 / unlimited / infinity / max. Since systemd driver is backed by fs driver, and both fs and fs2 set the limit of -1 properly, it works, but systemd still has the old value: # runc --systemd-cgroup update $CT --pids-limit 42 # systemctl show runc-$CT.scope | grep TasksMax TasksMax=42 # cat /sys/fs/cgroup/system.slice/runc-$CT.scope/pids.max 42 # ./runc --systemd-cgroup update $CT --pids-limit -1 # systemctl show runc-$CT.scope | grep TasksMax= TasksMax=42 # cat /sys/fs/cgroup/system.slice/runc-xx77.scope/pids.max max Fix by changing the condition to allow -1 as a valid value. NOTE other negative values are still being ignored by systemd drivers (as it was done before). I am not sure whether this is correct, or should we return an error. A test case is added.
