Package: iputils-tracepath
Version: 3:20161105-1
Severity: important

Dear Maintainer,

It seems that traceroute6.iputils fails to work when given an address
instead of a hostname:

$ traceroute6.iputils localhost
traceroute to  (::1) from ::1, 30 hops max, 24 byte packets
 1  localhost (::1)  0.052 ms  0.021 ms  0.022 ms

$ traceroute6.iputils ::1
traceroute to ::1 (::1) from ::1, 30 hops max, 24 byte packets
sendto: Invalid argument
 1 traceroute: wrote ::1 24 chars, ret=-1
 *sendto: Invalid argument
traceroute: wrote ::1 24 chars, ret=-1
 *sendto: Invalid argument
traceroute: wrote ::1 24 chars, ret=-1
 *
sendto: Invalid argument
 2 traceroute: wrote ::1 24 chars, ret=-1
 *sendto: Invalid argument
traceroute: wrote ::1 24 chars, ret=-1

The differance in sendto seems to be the port number 33434 vs 0:

# strace traceroute6.iputils localhost
sendto(4, "\0\0\1\253\0\0\0\3\334\327.Y\0\0\0\0e\177\2\0\0\0\0\0", 24, 0, 
{sa_family=AF_INET6, sin6_port=htons(33434), inet_pton(AF_INET6, "::1", 
&sin6_addr), sin6_flowinfo=htonl(0), sin6_scope_id=0}, 28) = 24

# strace traceroute6.iputils ::1
sendto(4, "\0\0\1\232\0\0\0\3\227\327.Y\0\0\0\0\202\237\7\0\0\0\0\0", 24, 0, 
{sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::1", 
&sin6_addr), sin6_flowinfo=htonl(0), sin6_scope_id=0}, 28) = -1 EINVAL (Invalid 
argument)
