[ptxdist] [PATCH v2] iputils: update s20121221 -> s20161105

[Clemens Gruber]

The current version of iputils ping can handle IPv4 and IPv6 but
requires a crypto library dependency for ICMPv6 NI queries.
Add all possible choices: libgcrypt, nettle, openssl or none

tracepath works with IPv4 as well as IPv6 and it does not have to run as
root.
traceroute6 only works with IPv6 and requires superuser privileges.

on Debian traceroute6.iputils isn't setuid root and works for me. It has
caps set however:

	$ ls -l /usr/bin/traceroute6.iputils
	-rwxr-xr-x 1 root root 18936 Nov 10 07:23 /usr/bin/traceroute6.iputils

	$ /sbin/getcap /usr/bin/traceroute6.iputils
	/usr/bin/traceroute6.iputils = cap_net_raw+ep

Would that work here, too?

Best regards
Uwe

In theory yes, but I think our image generation tools cannot handle this.

mk2fs from e2fsprogs can generate images with extended attributed. I
used it to build imagea with ima/evm attributes.

OK, but we should probably do this in a separate patch and maybe not
only for traceroute6 but for all binaries for which ptxdist currently sets
the setuid bit?
(ping in inetutils, mtr, pppd, gst-ptp-helper in gstreamer1, ..)

Thanks,
Clemens
