Subject: Handle queries indefinitely on each TCP connection
X-Git-Tag: v9.21.7~45^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=575a8745822ea4da706e8c7a93ad234d04b3cd03;p=thirdparty%2Fbind9.git

Handle queries indefinitely on each TCP connection

Instead of closing every incoming TCP connection after handling a single
query, continue receiving queries on each TCP connection until the
client disconnects itself.  When coupled with response dropping, this
enables silently receiving all incoming data, simulating an unresponsive
server.
