RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
There is a bug in ruby stdlib Net::HTTP class which prevents connecting to hosts using IPv6.
Version-Release number of selected component (if applicable):
[root@rh72-node1:~]# ruby -v
ruby 2.0.0p598 (2014-11-13) [x86_64-linux]
[root@rh72-node1:~]# rpm -q ruby
ruby-2.0.0.598-25.el7_1.x86_64
How reproducible:
easily, always
Steps to Reproduce:
[root@rh72-node1:~]# irb
irb(main):001:0> require 'net/http'
=> true
irb(main):002:0> myhttp = Net::HTTP.new("::1")
=> #<Net::HTTP ::1:80 open=false>
irb(main):003:0> myhttp.start
URI::InvalidURIError: the scheme http does not accept registry part: ::1:80 (or bad hostname?)

from /usr/bin/irb:12:in `<main>'
irb(main):006:0>
Actual results:
Ruby does not even try to connect to localhost no matter if the address is enclosed in [] (which is wrong anyways) or not.
Expected results:
irb(main):001:0> require 'net/http'
=> true
irb(main):002:0> myhttp = Net::HTTP.new("::1")
=> #<Net::HTTP ::1:80 open=false>
irb(main):003:0> myhttp.start
Errno::ECONNREFUSED: Connection refused - connect(2) for "::1" port 80

from /usr/share/ruby/net/http.rb:879:in `open'
from /usr/share/ruby/net/http.rb:879:in `block in connect'

from /usr/share/ruby/net/http.rb:858:in `start'
from (irb):3
from /usr/bin/irb:11:in `<main>'
irb(main):004:0>
Ruby tries to connect to localhost. Since there is no HTTP server running, it gets Errno::ECONNREFUSED, that is not an issue.
