[Bug-tar] paxutils: unable to work over ipv6

[Pavel Raiskup]

Hi,

$Subject is truth because of gethostbyname call from paxutils which works
for ipv4 only.  We should use getaddrinfo these days for checking for
existing hostname/ip address.

Steps to reproduce (linux):

  $ sudo ifconfig em1 inet6 add         aaaa:aaaa:2:1::aaaa:1/64
  $ sudo route -A inet6 add default gw  aaaa:aaaa:2:1::1
  $ sudo su - -c 'echo "aaaa:aaaa:2:1::aaaa:1 test_domain"  >> /etc/hosts'
  $ ping6 test_domain 
  PING test_domain(test_domain) 56 data bytes
  64 bytes from test_domain: icmp_seq=1 ttl=64 time=0.047 ms
  ^C
  --- test_domain ping statistics ---
  1 packets transmitted, 1 received, 0% packet loss, time 0ms
  rtt min/avg/max/mdev = 0.047/0.047/0.047/0.000 ms
  $ # Configure tar with $RSH & --with-rmt pointing to correct binaries
  $ RSH=/usr/bin/ssh ./configure --with-rmt=/usr/sbin/rmt
  $ ./src/tar -cvf test_domain:/tmp/test.tar Makefile
  tar: Cannot connect to test_domain: resolve failed

Fix for paxutils attached.
