* libcli: Add ads_dns_query_srv_send()/recv()Volker Lendecke2020-12-113-0/+615
| | | | | | | | | | | | | This issues the "query" for SRV records site-aware and siteless. If there are SRV records returned without IP addresses, it will issue A and AAAA requests, waiting up to async_dns_timeout seconds. If that timeout is reached, ads_dns_query_srv_recv() returns whatever is around.

* libcli/dns: make 'clidns' private library out of DNS code in WAF buildAlexander Bokovoy2012-05-231-1/+1
| | | | | | | | | | | | | | | | 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.
* Introduce system MIT krb5 build with --with-system-mitkrb5 option.Alexander Bokovoy2012-05-233-5/+5
| | | | | | | | | | | | | | | | | System MIT krb5 build also enabled by specifying --without-ad-dc When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level configure in WAF build we are trying to detect and use system-wide MIT krb5 libraries. As result, Samba 4 DC functionality will be disabled due to the fact that it is currently impossible to implement embedded KDC server with MIT krb5. Thus, --with-system-mitkrb5/--without-ad-dc build will only produce * Samba 4 client libraries and their Python bindings * Samba 3 server (smbd, nmbd, winbindd from source3/) * Samba 3 client libraries In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture. This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
* dns: fix comments and make s4/libcli/resolve dns resolver workingAlexander Bokovoy2012-05-231-3/+3
| | | | | | | | After migrating to use libaddns, reply_to_addrs() needed to change the way answers are iterated through. Originally libroken implementation gave all answers as separate records with last one being explicitly NULL. libaddns unmarshalling code gives all non-NULL answers and should be iterated with explicit reply->num_answers in use.
