Author: syrinx Date: Fri Mar 19 09:53:25 2010 New Revision: 205312 URL: http://svn.freebsd.org/changeset/base/205312 Log: Make sure the snmp_pf module will first refresh its entires if necessary, then find a specific entry, and get the requested value. So far, it found the specific entry, refreshed the entry list if necessary, and got the requested value from the found entry. The problem is that refreshing nukes all old entries and replaces them with new ones and the obtained entry pointer was no longer valid after the refresh.
