Here's what seems to have happened: - A job was pending, waiting for resources. - slurm.conf was changed to remove some nodes, and a scontrol reconfigure was done. - As a result of the reconfigure, the pending job became non-runnable, due to "Requested node configuration is not available". The scheduler set the job state to JOB_FAILED and called delete_job_details. - scontrol reconfigure was done again. - read_slurm_conf called _restore_job_dependencies. - _restore_job_dependencies called build_feature_list for each job in the job list - When build_feature_list tried to reference the now deleted job details for the failed job, it got a segmentation fault. The problem was reported by a customer on Slurm 2.2.7. I have not been able to reproduce it on 2.4.0-pre3, although the relevant code looks the same. There may be a timing window. The attached patch attempts to fix the problem by adding a check to _restore_job_dependencies. If the job state is JOB_FAILED, the job is skipped.

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.

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.
