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