Hi,

With slurm 2.3.2 (or 2.3.3), I encounter the following error when
trying to launch as root a command attached to a running user's job
even if I use the --uid=<user> option :

sila@suse112:~> squeue
   JOBID PARTITION     NAME     USER    STATE      TIME TIMELIMIT
NODES   CPUS NODELIST(REASON)
     551     debug mysleep.     sila  RUNNING      0:02 UNLIMITED
1      1 n1

root@suse112:~ # srun --jobid=551 hostname
srun: error: Unable to create job step: Access/permission denied
<--normal behaviour

root@suse112:~ # srun --jobid=551 --uid=sila hostname
srun: error: Unable to create job step: Invalid user id <--problem

By increasing slurmctld verbosity, the log files displays the follwing
error :

slurmctld: debug2: Processing RPC: REQUEST_JOB_ALLOCATION_INFO_LITE from
uid=0
slurmctld: debug:  _slurm_rpc_job_alloc_info_lite JobId=551 NodeList=n1
usec=1442
slurmctld: debug2: Processing RPC: REQUEST_JOB_STEP_CREATE from uid=0
slurmctld: error: Security violation, JOB_STEP_CREATE RPC from uid=0 to
run as uid 1001

which occurs in function : _slurm_rpc_job_step_create
(src/slurmctld/proc_req.c)

Here's my patch to prevent the command from failing (but I'm not sure
that there is no side effects) :

to give a correct priority on the first decay cycle after a restart of the
slurmctld. Patch from Martin Perry, Bull.
