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 Vitezslav Crhonek 2016-03-22 09:43:02 UTC 
Description of problem:
Currently, tog-pegasus stores SSL certificates in /etc/Pegasus directory. There is a requset to move them to better place (at least beacause of SELinux), see rhbz#1308809. It seems reasonable to move them to /etc/pki/Pegasus.

However, wbemcli has /etc/Pegasus hardcoded as default path to required certificate 'client.pem'. If the path changes, common https connection (without '-noverify' flag) will fail:

# wbemcli ei -nl 'https://root:$PASS@localhost:5989/root/cimv2:PG_OperatingSystem'
*
* wbemcli: Http Exception: Could not open CA certificate file: /etc/Pegasus/client.pem (No such file or directory)
*

Of course, it could be fixed by '-cacert /etc/pki/Pegasus' (or '-noverify'), but until that time any script using wbemcli would be broken - regression.
Comment 4 Alois Mahdal 2017-06-13 20:05:24 UTC 
I tried to reproduce this by running TC#289077 /CoreOS/sblim/tools/wbemcli-command-segfaults-when-called-with-https-scheme on a RHEL-7.4 compose with downgraded wbemcli:

    # rpm -ql tog-pegasus | grep pem$
    /etc/pki/Pegasus/client.pem
    /etc/pki/Pegasus/file.pem
    /etc/pki/Pegasus/server.pem
    /etc/pki/ca-trust/source/anchors/localhost-pegasus.pem
    # rpm -q tog-pegasus sblim-wbemcli
    tog-pegasus-2.14.1-5.el7.x86_64
    sblim-wbemcli-1.6.2-10.el7.x86_64
    # 


I get different message, though:

    :: [  BEGIN   ] :: Running 'wbemcli ei 'https://pegasus:test@localhost:5989/root/cimv2:Linux_BlockStorageStatisticalData' > TESTOUT'
    *
    * wbemcli: Http Exception: Problem with the SSL CA cert (path? access rights?)
    *

Is it possible that the error message has changed?  Or I'm doing something wrong?

The message in comment#1 is from the latest version of sblim-wbemcli and it differs from the version shipped within RHEL7.
Comment 6 Alois Mahdal 2017-06-16 03:46:49 UTC 
OK, so I tried running a slightly modified version of test TC#289077 (just to run something with HTTPS) with following version combinations:

    tog-pegasus   | sblim-wbemcli || result
    ==============|===============||========
     2.14.1-3.el7 | 1.6.2-10.el7  || pass
     2.14.1-3.el7 | 1.6.2-11.el7  || fail
     2.14.1-5.el7 | 1.6.2-10.el7  || fail
     2.14.1-5.el7 | 1.6.2-11.el7  || pass

This is expected behavior: if tog-pegasus is updated, sblim-wbemcli must be updated as well.  (Errata dependencies are set in a way that guarrantees that either both or none will be available at the same time.)
