Subject: iputils.hh: NetmaskTree: Make the node_type key value const.
X-Git-Tag: auth-4.3.0-beta2~20^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0c4df7c3e67ff379f2747a522e6290618c18a2a1;p=thirdparty%2Fpdns.git

iputils.hh: NetmaskTree: Make the node_type key value const.

This prevents changing the key used by the tree, which would otherwise provide
an opportunity to corrupt the tree.
