Summary0003449: restorecon breaks selinux contexts in /var/named/chroot/proc (which is bind mounted to /proc so breaks that too)
DescriptionThe /proc mount is set up to not be touched by restorecon. However, /var/named/chroot/proc inherits system_u:object_r:named_conf_t:s0, which then makes the main /proc filesystem a complete mess and causes thousands of SELinux denials from processes accessing their own file descriptors and sockets.

There needs to be a '<<None>>' rule for /var/named/chroot/proc(/.*)?

[root@gateway selinux]# semanage fcontext -l | grep ^/proc
/proc/.* all files <<None>>
/proc directory <<None>>
[root@gateway selinux]# semanage fcontext -l | grep ^/var/named/chroot

That looks like a policy bug/enhancement which should be handled upstream. Would you mind opening a bug report at https://bugzilla.redhat.com/ for this issue and give us the link to that bug report here?

Thank you.

Thanks for your quick response. I wasn't really sure how bug reporting worked for CentOS... I haven't paid for RHEL so I wasn't sure if they'd accept bug reports upstream. Are they happy for CentOS users to submit bugs there?

Yes. They even have a box where you can check external bugreports which has the CentOS bug tracker in it.
