The inet(4) manpages describes it as: ip.process_options Integer: control IP options processing. By setting this variable to 0, all IP options in the incoming packets will be ignored, and the packets will be passed unmodified. By setting to 1, IP options in the incoming packets will be processed accordingly. By setting to 2, an ICMP ``prohibited by filter'' message will be sent back in respose to incoming packets with IP options. Default is 1. This sysctl(8) variable affects packets destined for a local host as well as packets forwarded to some other host. >How-To-Repeat: Either search for "process_options" in the FreeBSD Kernel Cross Reference: http://fxr.watson.org/fxr/search?string=process_options or run: /usr/bin/fgrep -l process_options /usr/src >Fix: Either patch inet(4) and delete the sysctl, or implement such functionality. >Release-Note: >Audit-Trail: >Unformatted:
