New submission from Brett R :
We are seeing a crash apparently in crypt.py when invoked via SaltStack and
have narrowed it down to some change in the Linux kernel introduced by this
security update: https://access.redhat.com/errata/RHSA-2018:3083
Linux kernel 3.10.0-862.14.4.el7.x86_64 works fine
Linux kernel 3.10.0-957.el7.x86_64 and later show this error:
