+Subject: [PATCH] resolved: do not allocate packets with minimum size
+
+dns_packet_new() is sometimes called with mtu == 0, and in that case we should
+allocate more than the absolute minimum (which is the dns packet header size),
+otherwise we have to resize immediately again after appending the first data to
+the packet.
+
+This partially reverts the previous commit.
