frr-8.5.1-4 Selinux policy changes: - Allow watch,read on /var/run/netns directory and its content - Add sys_admin capability It seems like sys_admin is needed because frr is using setns function to change the actual namespace.

Allow frr daemons bind generic sockets to tcp ports The vrrpd and pathd daemons need to bind to ports 2619/tcp and 2621/tcp. This commit can be reverted if the inter-process communication changes to using unix sockets in the future.
