Subject: [PATCH] selinux: allow oddjobd to set up ipa_helper_t context for
execution
On Fedora 32+ and RHEL 8.3.0+ execution of ipa_helper_t context requires
SELinux policy permission to use 'noatsecure'. This comes most likely
from execve() setup by glibc.
Add SELinux interface ipa_helper_noatsecure() that can be called by
oddjob's SELinux policy definition.
In addition, if ipa_helper_t runs ipa-getkeytab, libkrb5 will attempt to
access SELinux configuration and produce AVC for that. Allow reading
general userspace SELinux configuration.
