glusterd: Bug fixes for IPv6 support
Backport of http://review.gluster.org/#/c/11988/
Problem:
Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration,
1. glusterd needs to listen on default port (240007) as IPv6 TCP listner.
2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe
needs to work using ipv6 addresses.
3. Bricks needs to listen on ipv6 addresses.
All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.
Fix:
When "option transport.address-family inet6" option is present in glusterd.vol
file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved
inside brick volume files used by glusterfsd brick process when they are starting.
Tests Run:
Regression tests using ./run-tests.sh
IPv4: Regression tests using ./run-tests.sh for release-3.7 branch verified by comparing with clean repo.
IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts)
Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here
