--- Comment #6 from Steve McDaniel <steve.mcdaniel at bitplatter.com> ---
It looks like this bug still exists in 4.0.

See:
https://github.com/gluster/glusterfs/blob/release-4.0/xlators/features/selinux/src/selinux.c#L192

and:

https://github.com/gluster/glusterfs/blob/release-4.0/xlators/features/selinux/src/selinux.c#L150

Excerpt from original report:
   > Should line 150 and 192 xlators/features/selinux/src/selinux.c of be

   > if (!priv->selinux_enabled || !dict)

   > instead of

   > if (!priv->selinux_enabled && !dict)



Bug was reported against Gluster 3.13.2 and is still present in 3.13.x

See bug report here: https://bugzilla.redhat.com/show_bug.cgi?id=1552228


This bug will cause the brick process to SEGFAULT due to a NULL ptr deref, and
the whole gluster volume will go down.


Bug is reproducible during a gluster rebalance if selinux is set to a DISABLED
state on the gluster node.
