Hi David
The purpose of this patch was to allow the transparent proxy application
to block the specific socket ranges to prevent the communication on the
specific ports.
Dropping packets for this particular port using iptables could lead to
applications on the system getting stuck without getting a socket error.
If bind fails explicitly, the application can atleast retry for some
other
port.
Is there some alternate existing mechanism to achieve this already?
