Unbound regex in config options

[Jim Rollenhagen]

Oslo.config uses re.search() to check config values against the allowed regex. This checks if the regex matches anywhere in the string, rather than checking if the entire string matches the regex.

Nova has three config options that appear as if the entire string should match the given regex:
* DEFAULT.instance_usage_audit_period
* cinder.catalog_info
* serial_console.port_range

However, these are not bounded with ^ and $ to ensure the entire string matches.

    Ensure config regexes match the entire string

    Oslo.config uses re.search() to check config values against the allowed
    regex. This checks if the regex matches anywhere in the string, rather
    than checking if the entire string matches the regex.

    Make sure config options where the entire string should match the given
    regex actually do so.
