>Description:
My ssh daemon is running on port 8691, uid for that process is 22, gid is 22.
Kernel security is enabled and kern.securelevel is set as 1337.

Compiled kernel with options:
options MAC
options MAC_PORTACL

Specified kernel tunables in sysctl.conf:
security.mac.portacl.enabled=1
security.mac.portacl.rules=uid:80:tcp:80,uid:80:tcp:443,uid:22:tcp:8691

On system boot, when the tunables are read from sysctl.conf, a page error occurs when reading the rules. I believe this to happen because the highest port that portacl is configured (by default) to watch is 1023 but my ruleset was configured to have portacl active on 8691.
