[bug-inetutils] [PATCH] traceroute: Remove geteuid test.

[Mats Erik Andersson]

Dear all,

the present code "src/traceroute.c" contains a test that the
effective user be "root" at execution time. The corresponding
test is lacking in "ping/ping.c" and "ping/ping6.c". The outcome
is that in GNU/Linux

   setcap cap_net_raw=ep ping/ping
   setcap cap_net_raw=ep ping/ping6

provide full functionality without use of the set-uid-bit.
In contrast,

   setcap cap_net_raw=ep src/traceroute

does not have any effect, since the code aborts prior
to the use of the relevant capability.

Using the following patch, any distributor or administrator
gets the option of continued use of the set-uid-bit, or a new
use of file capabilities for either of

    ping, ping6, or traceroute

when built from our sources.


Best regards,
  Mats
