Description Andrew Price 2015-03-30 13:15:24 UTC 
Description of problem:

pcs cluster stop --all (and similar commands) fails due to SSL certificate verification failure.

Version-Release number of selected component (if applicable):

pcs-0.9.139-3.fc23.x86_64
python-2.7.9-5.fc22.x86_64

How reproducible:
100%

Steps to Reproduce:
1. On one node, do pcs cluster stop --all

Actual results:

[root@rawhide1 ~]# pcs cluster stop --all
rawhide2: Unable to connect to rawhide2 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))
rawhide3: Unable to connect to rawhide3 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))
rawhide1: Unable to connect to rawhide1 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))
Error: unable to stop all nodes
rawhide2: Unable to connect to rawhide2 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))
rawhide3: Unable to connect to rawhide3 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))
rawhide1: Unable to connect to rawhide1 ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581))


Expected results:

Cluster stops on all nodes.

Additional info:

This is caused by a recent tightening of urllib2's SSL cert checking:  https://www.python.org/dev/peps/pep-0476/

The previous cert checking behaviour (which is prone to MITM attacks) could be reinstated using something like

    sslcontext = ssl._create_unverified_context()
    opener = urllib2.build_opener(
        urllib2.HTTPSHandler(context=sslcontext),
        urllib2.HTTPCookieProcessor()
    )

in sendHTTPRequest() in pcs/utils.py.
