| 6 | tristate "DNS Resolver support" | |
| 7 | depends on NET && KEYS | |
| 8 | help | |
| 9 | Saying Y here will include support for the DNS Resolver key type | |
| 10 | which can be used to make upcalls to perform DNS lookups in | |
| 11 | userspace. | |
| 12 | ||
| 13 | DNS Resolver is used to query DNS server for information. Examples | |
| 14 | being resolving a UNC hostname element to an IP address for CIFS or | |
| 15 | performing a DNS query for AFSDB records so that AFS can locate a | |
| 16 | cell's volume location database servers. | |
| 17 | ||
| 18 | DNS Resolver is used by the CIFS and AFS modules, and would support | |
| 5227bbb0 | 19 | SMB2 later. DNS Resolver is supported by the userspace upcall |
| 1a4240f4 WL |
20 | helper "/sbin/dns.resolver" via /etc/request-key.conf. |
| 21 | ||
| 22 | See <file:Documentation/networking/dns_resolver.txt> for further | |
| 23 | information. | |
| 24 | ||
| 25 | To compile this as a module, choose M here: the module will be called | |
| 26 | dnsresolver. | |
| 27 | ||
| 28 | If unsure, say N. |
