Class FirewallZone.Name

All Implemented Interfaces:
DtoFactory<FirewallZoneName>, Internable<FirewallZone.Name>, Serializable, Comparable<FirewallZone.Name>
Enclosing class:

public static final class FirewallZone.Name extends Object implements Comparable<FirewallZone.Name>, Serializable, DtoFactory<FirewallZoneName>, Internable<FirewallZone.Name>
Represents a name that may be used for a FirewallZone. Zones names must:
  • Be non-null
  • Be non-empty
  • Be between 1 and 17 characters
  • Contain the characters [a-z], [A-Z], [0-9], underscore (_), hyphen (-), and slash (/)
  • Not begin with a slash (/)
  • Not end with a slash (/)
  • Not contain more than one slash (/)

We're unable to find well-defined rules for valid zone names. The rules above are based on the source code for firewalld included with CentOS 7.

  1. See /usr/lib/python2.7/site-packages/firewall/core/io/, check_name.
  2. See /usr/lib/python2.7/site-packages/firewall/core/io/, check_name.
  3. See /usr/lib/python2.7/site-packages/firewall/, max_zone_name_len.

Additionally, we tried creating a new zone with some UTF-8 characters, specifically Japanese, and firewalld-cmd just stalled, not even responding to Ctrl-C. We are implementing with a strict ASCII-compatible definition of "alphanumeric".
