Replace two xstrcat() calls per argument with a single xmalloc() call. This significantly speeds up handling of REQUEST_JOB_INFO RPCs when some jobs have long argument lists.

Change argc from uint16_t to uint32_t in slurmctld and slurmstepd. Rest of the code already use uint32_t for argc.

In current version of slurm initscript, a stop action returns a non null exit code as slurmstatus exit code is directly used and the daemons are stopped. Ensure that when called from slurmstop, slurmstatus error code is reversed to correctly match the attended error code of the stop stage.

is a convenience function in BSD and glibc that internally calls the equivalent of int masterfd = open("/dev/ptmx", flags); grantpt (masterfd); unlockpt (masterfd); int slavefd = open (slave, O_RDRW|O_NOCTTY); (in psuedocode) On Linux, with some combinations of glibc/kernel (in this case glibc-2.14/Linux-3.1), the equivalent of grantpt(3) was failing in slurmstepd with EPERM, because the allocated pty was getting root ownership instead of the user running the slurm job. From the POSIX description of grantpt: "The grantpt() function shall change the mode and ownership of the slave pseudo-terminal device... The user ID of the slave shall be set to the real UID of the calling process..." http://pubs.opengroup.org/onlinepubs/007904875/functions/grantpt.html This means that for POSIX-compliance, the real user id of slurmstepd must be the user executing the SLURM job at the time openpty(3) is called. Unfortunately, the real user id of slurmstepd at this point is still root, and only the effective uid is set to the user. This patch is a work-around that uses the (non-portable) setresuid(2) system call to reset the real and effective uids of the slurmstepd process to the job user, but keep the saved uid of root. Then after the openpty(3) call, the previous credentials are reestablished using the same call.

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) :
