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 Steve Grubb 2010-10-13 14:36:59 UTC 
Description of problem:
The currently shipped version of openscap is a mostly complete version that meets SCAP 1.0 requirements. Currently, NIST is certifying SCAP 1.1 tools. So, we need to update openscap so that it could be certified under NIST's 1.1 requirements. This means: 

Completing support for all required elements in all libraries
Updating OVAL to 5.6
Updating CPE to 2.2
Adding OCIL 2.0

It seems that this is not working properly, see attached enum-pattern-match.xml, it contains '<type operation="pattern match">ARPHRD_.*</type>':

# oscap oval eval enum-pattern-match.xml
1 1840 In file 'enum-pattern-match.xml' on line 48: Element '{http://oval.mitre.org/XMLSchema/oval-definitions-5#unix}type': [facet 'enumeration'] The value 'ARPHRD_.*' is not an element of the set {'ARPHRD_ETHER', 'ARPHRD_FDDI', 'ARPHRD_LOOPBACK', 'ARPHRD_VOID', 'ARPHRD_PPP', 'ARPHRD_SLIP', 'ARPHRD_PRONET', ''}.
1 1824 In file 'enum-pattern-match.xml' on line 48: Element '{http://oval.mitre.org/XMLSchema/oval-definitions-5#unix}type': 'ARPHRD_.*' is not a valid value of the local atomic type.
oscap was unable to validate the XML document you provided.
Please ensure that the XML document is valid and well-formed, and try again.

Validation failed. If I understand it well, interface type is an enumeration and in the latest openscap (more precisely, in the 5.6 language) it should be possible to specify a value from enumeration by a pattern.

hey Ondrej,

this seems to be a bug in official OVAL schemas. We will examines schemas and see if it's possible to fix them. But I hope this is not a blocker. 

btw. I have implemented new option called "--skip-valid" for oscap tool. This might be very helpful for you and other people when validation does not work properly (libxml2 issue or wrong schemas).

If I evaluate your content, I get
$ ./oscap oval eval --skip-valid  /home/pvrabec/a//enum-pattern-match.xml
Definition oval:1:def:1: true

To get this option into RHEL6.1 would require errata respin. If we have some more issues to fix I would recommend to go this way. ;)

Comment 25 Ondrej Moriš 2011-03-21 21:43:16 UTC 
Great, thanks a lot for this clarification. Since all new features were verified successfully, updated self-test is passing and oscap is able to evaluate SRT OVAL contents, I am moving this bug into VERIFIED state.
