Though I hope everyone is putting the bash shellshock patching in their rearview mirror, it might still help to be aware of a change to function exports that the latest version introduced. Instead of the corresponding environment variable being named "myfunction", it's now "BASH_FUNC_myfunction()".
This caused a bit of trouble for us when we patched some head nodes before compute nodes. Since job environments are created on the submission host, but run on the compute host, the compute hosts didn't understand/accept the environment variable definition. Along with the error message, our jobs lost the ability to load software environment modules (which is implemented with bash functions). Though not specific to Slurm, I think it's relevant here because of the sharing of environments across hosts that comes up in this context. We wrote up a bit more detail here: https://rc.fas.harvard.edu/shellshock-update-issue-temporarily-affecting-slurm-jobs-software-modules/ Hope that helps someone, John John Brunelle Harvard University FAS Research Computing, Informatics and Scientific Applications john_brune...@harvard.edu @jabrcx
