  8. Saying Y here will include support for the DNS Resolver key type
  9. which can be used to make upcalls to perform DNS lookups in
  10. userspace.
  11. DNS Resolver is used to query DNS server for information. Examples
  12. being resolving a UNC hostname element to an IP address for CIFS or
  13. performing a DNS query for AFSDB records so that AFS can locate a
  14. cell's volume location database servers.
  15. DNS Resolver is used by the CIFS and AFS modules, and would support
  16. SMB2 later. DNS Resolver is supported by the userspace upcall
  17. helper "/sbin/dns.resolver" via /etc/request-key.conf.
  18. See <file:Documentation/networking/dns_resolver.txt> for further
  19. information.
  20. To compile this as a module, choose M here: the module will be called
  21. dnsresolver.
  22. If unsure, say N.
