This prevents a hard-to-diagnose issue where slurmstepd may fail to start due to a missing library. This now ensures slurmd will fail, and keep the node down until the library issue can be fixed. Bug 4645, 4644.

fatal() calls exit(1) which precludes getting a backtrace. That's fine on configuration issues and other types of problem, but for hitting "impossible" edge cases getting a core dump may be the only way to isolate the issue. Adding to 17.11 so we can easily provide diagnostic patches without needing users to back-port this implementation. Further use will come in 18.08. Bug 4599.

Wait for the prolog to complete, and then clean up after it. Otherwise orphaned "sleep" executables will be created by the still-launching step_extern. Bug 4718.

keyvalue_initialized is reset on 'scontrol reconfigure' and other cases, which can lead to additional atfork handlers being registered. These can eventually lead to a segfault if an excessive number of handlers have been re-registered. Set a separate boolean to protect against this. Clear that boolean as part of the atfork handler. Bug 4628.

UsePss was correct, but UsePSS and usepss would be silently ignored, leading to confusion as to whether the option was working or not. Treat all JobAcctGatherParams as case-insensitive to avoid confusion. Bug 4637.

Commit 818a09e8 introduced a new state JOB_OOM and a new state reason FAIL_OOM (OutOfMemory). The problem was that it based the decision upon the value of the different memory.[*].failcnt being > 0. That lead to "false positives" situations when the usage hit the limit but the Kernel was able to reclaim pages and the process managed to finish successfully. When this happens there might not necessary be OOM_KILL events happening. This patch makes it so the JOB_OOM state is set based upon OOM_KILL events detected instead of usage hitting the limit. The usage hit will still be logged as an info() message, and further work will be needed in the master branch to better discern both type of events, maybe changing the API and getting rid of the current SIG_OOM and a potential new SIG_OOM_KILL. OOM_KILL event is detected using the eventfd notification mechanism on the cgroup v1 control/event files: https://www.kernel.org/doc/Documentation/cgroup-v1/memory.txt If we plan to support cgroup v2, we should monitor 'memory.events' file modified events. That would mean that any of the available entries changed its value upon notification. Entries include: low, high, max, oom, oom_kill: https://www.kernel.org/doc/Documentation/cgroup-v2.txt https://patchwork.kernel.org/patch/9737381 but since this is a fairly recent change many sites might be running kernels still not supporting this feature. Bug 3820.

This reverts commit d3141dc9. Bug 4655 Turns out there are many ways to get this information directly from the slurmstepd. As you can already get this information from ps we decided to just revert back to the old non-authenticated way of doing things. If we do need this in the future we need to patch the stepd as well as the slurmd here in all the RPC's that try to grab this. A user could easily run scontrol (or their own home baked thing) on the node which will give them a direct contact with the slurmstepd.
