# arpresolve should check the interface fib for routes to a target when

|
# creating an ARP table entry. This is a regression for kern/167947, where
|

# arpresolve only checked the default route.
|
|
#
|
|
# Outline:
|
|
# Create two connected epair(4) interfaces
|
|
# Use nping (from security/nmap) to send an ICMP echo request from one
|
|
# interface to the other, spoofing the source IP. The source IP must be
|
|
# spoofed, or else it will already have an entry in the arp table.
|
|
# Check whether an arp entry exists for the spoofed IP

|
# for the destination. If more than one were available, it would choose the

# default route, then trying to send a UDP packet with SO_DONTROUTE set to an
|
|
# address which is not routable on that FIB. Absent the fix for this bug,

|
# in_pcbladdr would choose an interface on any FIB with a default route. With
