| 82The 83.Nm 84policy works similar to 85.Xr ipfw 8 86or by using a 87.Em first match semantic . 88This means that not all rules are applied, 89only the first matched rule; thus if 90Rule A allows access and Rule B blocks 91access, Rule B will never be applied. 92.Pp 93.Ss Sysctls 94The following sysctls may be used to tweak the behavior of 95.Nm : 96.Bl -tag -width indent 97.It Va security.mac.bsdextended.enabled 98Set to zero or one to toggle the policy on or off. 99.It Va security.mac.bsdextended.rule_count 100List the number of defined rules, the maximum rule count is 101current set at 256. 102.It Va security.mac.bsdextended.rule_slots 103List the number of rule slots currently being used. 104.It Va security.mac.bsdextended.debugging 105Toggle between debugging mode, currently this does 106nothing and will soon be removed. 107.It Va security.mac.bsdextended.firstmatch_enabled 108Toggle between the old all rules match functionality 109and the new first rule matches functionality. 110.It Va security.mac.bsdextended.logging 111Log all access violations via the 112.Dv AUTHPRIV 113.Xr syslog 3 114facility. 115.It Va security.mac.bsdextended.rules 116Currently does nothing interesting. |
