2019-01-15libcli/dns: Add dns_lookupVolker Lendecke4-0/+435
Wrapper function to parse resolv.conf and talk to multiple nameservers. This is the code where we might want to add a "working nameserver" cache. glibc always looks at the first configured nameserver. If that's dead, glibc runs into a timeout and only then asks the second one that might succeed. When more than one dns query is to be performed, these timeouts add up.

2019-01-15libcli/dns: Add resolv.conf parsingVolker Lendecke4-1/+248
Right now this only looks at the nameserver setting. It is initally made for asynchronous AD DC lookup routines, where we don't need the "search", "domain" and other settings. When we convert general "net", "smbclient" and others to use this, we might either add "domain" handling to this code or look at something like c-ares which already does it.

Same signature as the UDP client in the same file. This opens and closes the socket per request. In the future, we might want to create a persistent TCP connection for our internal DNS server's forwarder. That will require proper handling of in-flight requests. Something for another day.

2012-05-23libcli/dns: make 'clidns' private library out of DNS code in WAF buildAlexander Bokovoy1-7/+5
After consolidating DNS resolver code to lib/addns, there is one piece that still needs to be moved into a common DNS resolver library: DNS_HOSTS_FILE subsystem. Unfortunately, direct move would require lib/addns to depend on libcli/util/{ntstatus.h,werror.h} (provided by errors subsystem). In addition, moving libcli/dns/* code to lib/addns/ would make conflicting the dns_tkey_record struct. The conflict comes from source4/dns_server/ and is due to use of IDL to define the struct. lib/addns/ library also provides its own definition so we either need to keep them in sync (rewrite code in lib/addns/ a bit) or depend on generated IDL headers. Thus, making a private library and subsystem clidns is an intermediate step that allows to buy some time fore refactoring.

2011-04-26libcli/dns Improve dns_hosts_file, using Samba3's struct dns_rr_srvAndrew Bartlett2-0/+483
By reworking the 'fake DNS' file to use struct dns_rr_srv it should be possible to emulate that resolver layer as well as the Samba4 sockaddr_storage* based layer. This will then give us a common DNS emulation for 'make test'. Andrew Bartlett
