tristate "DNS Resolver support"

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.txt> for further
|
|
information.
|
|
|
|
To compile this as a module, choose M here: the module will be called
|
|
dnsresolver.
|
|
|
|
If unsure, say N.
